Some time ago, Sichuan Chengdu announced the development of a special high-pressure valve for urea and applied for patent protection.
A urea special high pressure regulating valve has a main valve body, a lower valve body and a valve core integrated with the valve rod. An outflow flow passage is arranged on one side of the main valve body, and an inflow flow is arranged on the lower valve body. The method is characterized in that a valve cage is fixedly arranged in the main valve body, and the valve core is inserted into the valve cage through one end of the valve cage opening, and the end surface of the valve cage is opened on the other end and the lower valve body. The outlet end surface of the flow channel closely contacts to form a sealing pair, and the inner wall of the cage has an inwardly shrinking neck opening. The neck opening constitutes a valve opening that matches with the valve core, and the inner wall of the cage and the valve core. A gap is formed between the side walls to form an inner flow cavity, and the valve port is communicated with the inner flow cavity, and a gap is formed between the outer wall of the cage and the main valve body to form an outer flow cavity. In communication with the outer flow chamber, there are at least two outflow holes in the side wall of the cage for communicating the inner and outer flow chambers.
