Electric control type pressure reduction water conveying valve

Abstract

The invention belongs to the mechanical technical field and relates to fluid pressure execution mechanisms, particularly to an electric control type pressure reduction water conveying valve. The problems that the existing electric control type pressure reduction water conveying valve is poor in sealing performance and low in sensitivity are solved. The electric control type pressure reduction water conveying valve comprises a valve body and a valve cover, wherein the valve body comprises a cover opening and the valve cover is arranged on the valve opening; the valve cover is in an arched shape; a sealing platform is formed on the inner surface of the valve body in a protruding mode; a center line of the sealing platform and the axis of the cover opening are located on the same straight line; a cup is arranged between the valve cover and the valve body; circular-arc-shaped first reinforcing ribs are formed on the outer surface of the cup in a protruding mode; the first reinforcing ribs can abut against the sealing platform; a spring assembly is arranged between the valve cover and the cup; one end of the spring assembly is arranged on the cup; the other end of the spring assembly abuts against the inner surface of the valve cover. According to the electric control type pressure reduction water conveying valve, the sealing performance is good, the pressure in the valve body is stable, and the sensitivity is high.

Description

technical field [0001] The invention relates to a fluid pressure actuator, in particular to an electronically controlled decompression water delivery valve. Background technique [0002] The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure and relies on the energy of the medium itself to automatically maintain the outlet pressure. From the point of view of fluid mechanics, the pressure reducing valve is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid are changed, resulting in different pressure losses, so as to achieve the purpose of decompression. Then rely on the adjustment of the control and regulation system to balance the fluctuation of the post-valve pressure with the spring force, so that the post-valve pressure remains constant within a certain error range. [0003] The pressure reducing valve is a specia...

Problems solved by technology

[0004] However, in the prior art, the valve body and the bonnet are mostly connected by screws, and the influence of water flow impurities is not considered. The pressure reducing valve has a large volume, high production cost, low sensitivity, and low sealing performance. It is easy to cause water flow impurities to enter the water flow pressure reducing valve, which will affect the water flow pressure reducing effect and damage the water flow pressure reducing valve.
