Briefly describes the basic structure and working principle of hydraulic pneumatic valve

on the working principle, hydraulic pneumatic valve pneumatic valve core has been used in the relative motion of the pneumatic valve body to control the on-off of pneumatic valve opening and make the size of the in order to realize the control pressure, flow and direction. All hydraulic pneumatic valve, pneumatic valve, pneumatic valve size, pneumatic valve into the mouth, the pressure difference between the oil outlet, and through the relationship between the pneumatic valve flow meet the orifice flow formula ( Q = KA Δ PM, just all kinds of pneumatic valve control the parameters of each are not identical. 。 Briefly describes the basic structure and working principle of hydraulic pneumatic valve mainly includes the basic structure of hydraulic pneumatic valve, pneumatic valve, pneumatic valve core and drives pneumatic valve core in the pneumatic valve body do relative movement of the operating device. The main form of pneumatic valve core has a slide pneumatic valve, pneumatic valve and ball valve cone; Pneumatic valve in addition to cooperate with pneumatic valve core of the pneumatic valve body hole or pneumatic valve seat hole, and external pipeline oil outlet and inlet and drain mouth; Driven by pneumatic valve core in the pneumatic valve body do relative movement of the device can be manual adjustment mechanism, can also be a spring or electromagnet, some places still driven by hydraulic pressure. On the working principle, hydraulic pneumatic valve pneumatic valve core has been used in the relative motion of the pneumatic valve body to control the on-off of pneumatic valve port and the size of the read, in order to realize the control pressure, flow and direction. Our main products are: pneumatic pneumatic valves, pneumatic ball valves, pneumatic butterfly valve, pneumatic actuators, http://www. /。
