Pneumatic control valve usually pneumatic actuators and control valves connected to the installation of the formation of a combination of debugging. Pneumatic control valve installation and commissioning is extremely important, this article describes the pneumatic control valve installation details and tips: A. installation process should always follow the pneumatic control valve installation instructions and attention points; B. control valve working environment temperature (- 30 ~ +60) Relative humidity not more than 95% 95%, relative humidity not more than 95%; C. Regulating valve position should have a straight pipe section, the length of not less than 10 times the pipe diameter (10D) Too short to affect flow characteristics; D. Before installing the valve, read the instruction manual. Instruction Manual Describes the product and precautions and precautions to be observed before and during installation. E. Confirming Pipe Cleaning: Foreign objects in the pipe may damage the sealing surface of the valve or even impede movement of the valve plug, ball and disc Cause the valve can not be properly closed. In order to reduce the possibility of dangerous situations, it is necessary to clean all the pipes before installing the valve. Make sure to remove pipe dirt, metal debris, welding slag and other foreign objects. In addition, inspect the pipe flange to ensure that there is a smooth gasket surface. If the valve has a threaded end, apply a high grade pipe sealant to the male thread of the pipe. Do not apply sealant to the female thread because the excess sealant on the female thread will be squeezed into the body. Excess sealant can cause plugging or dirt accumulation on the spool resulting in the valve not closing properly. F. Carefully inspect the regulator: Prior to installation, inspect and remove all shipping stops, protective plugs or shims Surface cover, check the valve body to ensure that there is no foreign body; H. Regulating valve should be installed in the horizontal pipe, and up and down perpendicular to the pipeline, generally under the valve to be supported to ensure a solid and reliable. For special occasions, the need for regulating valve installed in the vertical pipe when the valve should also be supported (except for small-caliber control valve). Install to avoid additional stress on the regulator); G. Make sure there is enough space above and below the valve for easy disassembly of the actuator or valve plug for inspection and maintenance. For flanged valve bodies, make sure that the flange faces are properly aligned so that the gasket surface contacts evenly. After the flange is centered, gently tighten the bolts and finally tighten the bolts in a staggered pattern. Pneumatic control valve in the storage and installation precautions: A. The valve should be stored in a dry room, both ends of the pathway must be blocked, not allowed to heap storage; B. Long-term storage of the control valve should be regularly inspected to remove dirt in the The movement parts and the processing surface should be coated with anti-rust oil, to prevent rust; C. The valve should be installed in the horizontal pipe, compulsory vertical installation, valve stem upward; D. compulsory according to the arrow pointing finger medium installation .
