In his interview, Xiao Gang emphasized in particular that since the advent of the digital age, the Chinese people's advantages have been reflected in their vividness. 'Security has entered the digital age. China's labor cost advantage and excellent learning ability are all important reasons for fighting foreign companies and overseas legions. In recent years, in the collision with overseas security companies, second-tier or small and medium-sized security companies have repeatedly won overseas, and global security practitioners have ceased to superstition such top international brands as Bosch and Honeywell. '
In fact, in recent years, China's security market has rapidly emerged as an important force in the world's security industry. According to the “2014-2018 China Security Industry Market Preview and Investment Strategic Planning Analysis Report†data analysis, from 2006 to 2011, the security industry market scale increased from 120 billion yuan to 269.6 billion yuan, and the compound growth rate reached 17.61%. The conservative estimate of the compound annual growth rate for the next five years will also reach 15%. Reports issued by the HC Security Network Research Department also show that by 2015, China’s security market will have a minimum scale of 471.5 billion yuan and the highest level will reach 559 billion yuan.
With the improvement of the overall strength of China's security companies, more and more Chinese security companies have begun to focus their attention on overseas markets, presenting a collective maritime trend. Moreover, 'the market is no longer superstitious about the few leading companies in the country, and the overseas security market has grown into an opportunity for all security companies, rather than a few dedicated companies. As long as you do a good enough, fast enough, you can get a share in the current international security market. '
While affirming the future development prospects of China's security companies, Xiao Gang also stressed that not all security companies can succeed in future competition. 'Only those large and medium-sized companies that are willing to invest in technology or have a relatively stable development team and have more comprehensive product lines and solutions will be more likely to succeed in future competition. '
Xiao Gang said: 'China's security market is in a critical period of structural adjustment. After undergoing early rapid development, the security market will inevitably further shuffle the market and remove a number of vendors that do not possess core competitiveness, thus ensuring the rationalization of the entire industrial structure. In the next three years, the mainstream security market will be split between 15-20 core vendors. '
For this judgment, Xiao Gang made an extremely vivid description when he was interviewed by the “Security Market Newsâ€: The security industry has no genius, and everyone sees similar opportunities. The only difference is whether they can “step on pointâ€. The number of 'points' can even directly determine the company's 'life and death', because it involves probabilistic issues.
'For large companies that have the strength, they can lay out 100 points to 'step on', and as long as 50 successes can guarantee future development. For those small enterprises that can only step on one point or two points under the constraints of material, financial, and technical constraints, they will be eliminated once they step on the air. Therefore, in the long run, only those core manufacturers who have the strength will have more development potential. '
Of course, the accuracy of 'points' is also a direct test of the strength of enterprises and the wisdom of entrepreneurs. Take Blue Interstellar as an example. At present, BlueStar not only has a complete product line with high-medium and low-level cooperation, but also is the only security company with its own technology monitoring and management platform and hardware. The solutions provided by it are not only simple products, but also software management platforms supporting the products. This undoubtedly better meets customers' system integration and related compatibility issues.
In addition, in recent years, Blue Star has always adhered to a unique channel development strategy and adopted direct sales in areas where it is good at finance and education, and spent three years building its own distribution channels in other areas. In the process, despite encountering many difficulties, Blue Star has always insisted on its own initial choices, adopting a “friendship†approach with its partners to develop the market, and eventually succeeded. This point, as Xiao Gang said: 'There is no shortcut to the growth of the company. Only the direction is correct and incorrect, and the action persists and persists. We are fortunate that we have always insisted on being on the right path for ourselves. '
A ball check valve is a check valve in which the closing member, the movable part to block the flow, is a spherical ball. In some ball Check Valves, the ball is spring-loaded to help keep it shut. For those designs without a spring, reverse flow is required to move the ball toward the seat and create a seal. The interior surface of the main seats of ball check Valves are more or less conically-tapered to guide the ball into the seat and form a positive seal when stopping reverse flow.
Ball check valves are often very small, simple, and cheap. They are commonly used in liquid or gel minipump dispenser spigots, spray devices, some rubber bulbs for pumping air, etc., manual air pumps and some other pumps, and refillable dispensing syringes. Although the balls are most often made of metal, they can be made of other materials, or in some specialized cases out of artificial ruby. High pressure HPLC pumps and similar applications commonly use small inlet and outlet ball check valves with both balls and seats made of artificial ruby, for both hardness and chemical resistance. After prolonged use, such check valves can eventually wear out or the seat can develop a crack, requiring replacement. Therefore, such valves are made to be replaceable, sometimes placed in a small plastic body tightly-fitted inside a metal fitting which can withstand high pressure and which is screwed into the pump head.
There are similar check valves where the disc is not a ball, but some other shape, such as a poppet energized by a spring. Ball check valves should not be confused with Ball Valves, which is a different type of valve in which a ball acts as a controllable rotor to stop or direct flow.
A diaphragm check valve uses a flexing rubber diaphragm positioned to create a normally-closed valve. Pressure on the upstream side must be greater than the pressure on the downstream side by a certain amount, known as the pressure differential, for the check valve to open allowing flow. Once positive pressure stops, the diaphragm automatically flexes back to its original closed position.
A swing check valve or tilting disc check valve is check valve in which the disc, the movable part to block the flow, swings on a hinge or trunnion, either onto the seat to block reverse flow or off the seat to allow forward flow. The seat opening cross-section may be perpendicular to the centerline between the two ports or at an angle. Although swing check valves can come in various sizes, large check valves are often swing check valves. The flapper valve in a flush-toilet mechanism is an example of this type of valve. Tank pressure holding it closed is overcome by manual lift of the flapper. It then remains open until the tank drains and the flapper falls due to gravity. Another variation of this mechanism is the clapper valve, used in applications such firefighting and fire life safety systems. A hinged gate only remains open in the inflowing direction. The clapper valve often also has a spring that keeps the gate shut when there is no forward pressure. Another example is the backwater valve (for sanitary drainage system) that protects against flooding caused by return flow of sewage waters. Such risk occurs most often in sanitary drainage systems connected to combined sewerage systems and in rainwater drainage systems. It may be caused by intense rainfall, thaw or flood.
A stop-check valve is a check valve with override control to stop flow regardless of flow direction or pressure. In addition to closing in response to backflow or insufficient forward pressure (normal check-valve behavior), it can also be deliberately shut by an external mechanism, thereby preventing any flow regardless of forward pressure.
A lift-check valve is a check valve in which the disc, sometimes called a lift, can be lifted up off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side. A guide keeps motion of the disc on a vertical line, so the valve can later reseat properly. When the pressure is no longer higher, gravity or higher downstream pressure will cause the disc to lower onto its seat, shutting the valve to stop reverse flow.
An in-line check valve is a check valve similar to the lift check valve. However, this valve generally has a spring that will 'lift' when there is pressure on the upstream side of the valve. The pressure needed on the upstream side of the valve to overcome the spring tension is called the 'cracking pressure'. When the pressure going through the valve goes below the cracking pressure, the spring will close the valve to prevent back-flow in the process.
A duckbill valve is a check valve in which flow proceeds through a soft tube that protrudes into the downstream side. Back-pressure collapses this tube, cutting off flow.
A pneumatic non-return valve.
Multiple check valves can be connected in series. For example, a double check valve is often used as a backflow prevention device to keep potentially contaminated water from siphoning back into municipal water supply lines. There are also double ball check valves in which there are two ball/seat combinations sequentially in the same body to ensure positive leak-tight shutoff when blocking reverse flow; and piston check valves, wafer check valves, and ball-and-cone check valves.
