Description
Technical Field
The utility model belongs to the technical field of the valve, a brass forging and pressing double-piston relief pressure valve is related to.
Background
The piston type pressure reducing valve adopts the opening degree of an opening and closing part in a control valve body to adjust the flow of a medium, reduces the pressure of the medium, adjusts the opening degree of the opening and closing part by means of the action of the pressure behind the valve, keeps the pressure behind the valve within a certain range, keeps the pressure at an outlet within a set range under the condition that the pressure at the inlet is continuously changed, protects the subsequent life and production appliances, and the valve is generally horizontally installed in a pipeline.
However, the diameter of a flow passage of the existing brass forging piston type pressure reducing valve does not meet the standard and the use requirement seriously, and the traditional piston type pressure reducing valve adopts a three-cavity structure and an upper inlet and lower outlet structure, so that the pressure drop is overlarge when the water consumption at the rear end is large, and the noise problem caused by the overhigh water pressure at a user end and the overlarge pressure difference between the front and the rear of the pressure reducing valve is caused.
Disclosure of Invention
The utility model aims at providing a brass forging and pressing double-piston relief pressure valve to the above-mentioned problem that exists among the prior art, solve above problem.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides a brass forging and pressing double-piston pressure reducing valve, is including the valve body that has the runner, the bottom that is located the upper cover of valve body top and is located the valve body below, the valve body right side sets up the water inlet, and the left side is provided with the delivery port, a serial communication port, on cover and wear to be equipped with holding screw, holding screw is located one end in the upper cover and is provided with the pressure regulating pad, be provided with the piston in the valve body, be provided with the pressure regulating spring in the upper cover, pressure regulating spring one end is supported and is leaned on installing on the pressure regulating pad, and the other end is supported and is leaned on installing on the piston, be provided with down piston assembly in the bottom, piston assembly installs in piston one end down.
In the above brass forging double-piston pressure reducing valve, the lower piston assembly is composed of a lower piston sleeved on the piston, a sealing gasket positioned between the piston and the lower piston, and an auxiliary spring positioned in the lower piston and having one end abutted against the other end of the piston and abutted against the bottom cover, and an O-shaped sealing ring I is arranged between the outer peripheral wall of the lower piston and the inner peripheral wall of the bottom cover.
In foretell two piston relief pressure valves of brass forging and pressing, piston one end is provided with supplies pressure regulating spring to support and leans on the installation step of installation, O type sealing washer two has between installation step and the valve body internal perisporium, the piston other end is provided with supplies down the bellying that the piston supports and leans on the installation, just sealed pad is located between bellying and the lower piston.
In the brass forging double-piston pressure reducing valve, the pressure gauge plugging cap of the pressure reducing valve is arranged on the left side of the valve body.
Compared with the prior art, this brass forging and pressing double-piston reducing valve structural design is reasonable, change the structure that traditional reducing valve went into down, adopt the structural design who advances to go out from top to bottom, and change traditional three chambeies into two chamber structures, realized increaseing the runner diameter, the pressure balance of piston has been realized, it is too big to have solved the big time pressure drop of rear end water consumption simultaneously, lead to the noise problem that the high velocity of flow that the too big leads to of user side water pressure low and pressure difference around the reducing valve causes, increase pressure balance design, make pressure fluctuation before the valve can not influence pressure after the valve.
