Embodiment 1

[0018] Such as figure 1 As shown, the circular gas pressure reducing valve includes a circular chamber A (301) and a circular chamber B (302). One end of the air inlet (1) is set on the circular chamber A (301). The other end of the port (1) is provided with a solenoid valve (6), and the solenoid valve 6 acts as a pressure reducing valve switch. The lower end of the circular chamber A301 is provided with a bottom cover 1001, and the top of the circular chamber B302 is provided with a top cover 1002. 8. Mainly adjust the pressure of the pressure reducing valve at the air outlet. The water inlet 2 is arranged on the circular chamber A301, and the water outlet 7 is arranged on the top cover 1002. Water inlet 2 and water outlet 7 are arranged on the decompression valve, the cooling system of the present invention and engine is connected, and hot water flows in from water inlet 2, and hot water can guarantee that decompression valve works for a long time at the temperature of abo...

Embodiment 2

[0020] On the basis of Example 1, it also includes a gasket A901 and a gasket B902, the circular chamber A301 and the bottom cover 1001 are airtightly connected through the gasket A901, and the function of using the gasket A is to ensure The circular chamber A is perfectly sealed with the bottom cover. The circular chamber B302 is airtightly connected to the top cover 1002 through a sealing gasket B902, and the function of using the sealing gasket B is to ensure a perfect seal between the circular chamber B and the top cover.

Embodiment 3

[0022] On the basis of Embodiment 1, the operating voltage of the solenoid valve 6 is 12V, and the solenoid valve 6 needs to be connected with a car battery, and 12V can meet the usage requirements.

Abstract

The invention discloses a circular gas pressure reducing valve, comprising a circular cavity A (301) and a circular cavity B (302), wherein a gas inlet (1) is formed in the circular cavity A (301); an electromagnetic valve (6) is arranged on the gas inlet (1); the lower end of the circular cavity A (301) is provided with a bottom cover (1001); the upper end of the circular cavity B (302) is provided with a top cover (1002); a gas outlet (5) is formed in the circular cavity B (302); the top cover (1002) is internally provided with a spring control end (8); a water inlet (2) is formed in the circular cavity A (301); a water outlet (7) is formed in the top cover (1002). The circular gas pressure reducing valve has the advantages and the beneficial effects that the circular gas pressure reducing valve is communicated with a cooling system of an engine; hot water flows in from the water inlet; the hot water can guarantee the long-term work of the gas pressure reducing valve under about 50 DEG C temperature, so that the service life of the gas pressure reducing valve can be prolonged.

Description

technical field [0001] The invention relates to the technical field of gas valve devices, in particular to a circular gas pressure reducing valve. Background technique [0002] The gas 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 working principle of the p...
