进口高灵敏度蒸汽减压阀Product description:

进口高灵敏度蒸汽减压阀It belongs to pilot piston type pressure reducing valve. The highly sensitive steam pressure reducing valve consists of a main valve and a pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The pilot valve is mainly composed of valve seat, valve disc, diaphragm, spring, adjusting spring and other parts. Set the outlet pressure by adjusting the spring pressure, use the diaphragm to sense the change of outlet pressure, and adjust the size of the overflow area of the throttle part of the main valve by opening and closing the pilot valve to achieve the function of pressure reduction and stabilization. Working principle of high sensitivity steam pressure reducing valve: the high sensitivity steam pressure reducing valve is a valve that reduces the inlet pressure to a required outlet pressure through regulation, and automatically keeps the outlet pressure stable by relying on the energy of the medium itself. From the point of view of fluid mechanics, the pressure reducing valve is a throttling element whose local resistance can be changed,进口高灵敏度蒸汽减压阀 that is, by changing the throttling area, the flow rate and kinetic energy of the fluid can be changed, resulting in different pressure losses, so as to achieve the purpose of pressure reduction. Then, depending on the adjustment of the control and regulation system, the fluctuation of the pressure behind the valve is balanced with the spring force, so that the pressure behind the valve remains constant within a certain error range. Product features of high sensitivity steam pressure reducing valve: Based on the common pressure reducing valve, the following improvements have been made for the high sensitivity steam pressure reducing valve, increasing the piston area, changing the throttling structure, changing the sealing form, and improving the guide valve structure and regulating spring form, thus improving the product performance from the following aspects. ① The sensing efficiency and sensitivity of outlet pressure change are improved, and the pressure deviation caused by upstream pressure change and flow change is greatly reduced. ② The streamline distribution is improved and the noise is reduced.进口高灵敏度蒸汽减压阀 ③ The structure of the sealing surface is improved, and the service life of the sealing surface is prolonged. This product is mainly used for steam pipeline, which is suitable for steam pipeline with large inlet pressure change and flow change. High sensitivity steam pressure reducing valve is mainly used for steam pipeline, which is suitable for steam pipeline with large inlet pressure change and flow change.
