Embodiment 1

[0018] Such as figure 1 As shown, the end plate for controlling the pressure of the pressure reducing valve includes a cap-shaped end plate 1 , a pressure compensation port 3 is provided directly above the cap-shaped end plate 1 , and a mounting hole 2 is provided on the cap-shaped end plate 1 . The present invention is provided with a pressure compensation port on the hat-shaped end plate, which can ensure the long-term stable operation of the pressure reducing valve.

Embodiment 2

[0020] On the basis of Embodiment 1, a water outlet 4 is also included, and the water outlet 4 is arranged on the hat-shaped end plate 1 . The function of the water outlet is the water outlet of the circulating water when the pressure reducing valve heats up.

Embodiment 3

[0022] On the basis of Embodiment 1, at least three mounting holes 2 are provided on the hat-shaped end plate 1, so that the hat-shaped end plate can be firmly fixed on the valve body of the pressure reducing valve.

Abstract

The invention discloses an end plate for controlling the pressure of a pressure reducing valve. The end plate comprises cap-shaped end plate body (1). A pressure compensation opening (3) is formed right above the cap-shaped end plate body (1). A mounting hole (2) is formed in the cap-shaped end plate body (1). The end plate has the advantages that the pressure compensation opening is formed in the cap-shaped end plate body, and long-term stable operation of the pressure reducing valve can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of gas valves, in particular to an end plate for controlling the pressure of a pressure reducing valve. Background technique [0002] The pressure reducing valve is a special device that automatically reduces the working pressure of the pipeline. It can reduce the high liquid pressure in the pipeline before the valve to the level required by the pipeline after the valve. There are many structural types of pressure reducing valves, which can be divided into film type, spring film type, piston type, lever type and bellows type according to the structural form. According to the number of seats, it can be single-seat or double-seat. According to the position of the disc, it can be divided into positive action type and reverse action type. According to the medium, it can be divided into nitrogen pressure reducing valve, hydrogen pressure reducing valve, oxygen pressure reducing valve and so on. The basic w...
