Description
Technical field
The present invention relates to field of mechanical technique, and in particular to a kind of gas valve.
Background technology
Currently used for the pressure regulator valve on gas transmission pipeline, its structure is generally that valve is connected with gas passage flange.It is above-mentioned
Deficiency present in the pressure-regulating gas-transferring valve of structure is that the sealing effectiveness between valve body and gas passage is poor, if improving sealing effectiveness
The raising of manufacturing cost certainly will be caused.
The content of the invention
Instant invention overcomes above-mentioned shortcoming, and provide a kind of gas valve.
To achieve these goals, the present invention is to realize by the following technical solutions：The gas valve includes body, entered
In gas port, the first valve, gas outlet, the second valve, decompression diaphragm, pressure-reducing valve and relief spring, the exterior bottom of the body
The first valve is installed at heart right angle setting air inlet, the middle part of air inlet, and the outside top center right angle setting gas outlet of body goes out
The middle part of gas port is installed and set on the second valve, the left side side wall of body decompression diaphragm, and the left side central portion of decompression diaphragm, which is set, to be subtracted
Pressure valve, the inside of pressure-reducing valve sets two relief springs；The body, air inlet, the first valve, gas outlet, the second valve, subtract
Pressuring film plate, pressure-reducing valve and relief spring are integrally formed.
It is preferred that, the body is cylinder.
It is preferred that, the air inlet is identical with the specification of gas outlet.
It is preferred that, the specification of first valve and the second valve is identical.
It is preferred that, the lateral cross of the air inlet is circle.
It is preferred that, the relief spring is engineering spring.
The beneficial effects of the invention are as follows：It is simple in construction, easy to use, the good sealing effect between valve body and gas passage,
Production cost is low, long service life, it is easy to overhaul.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
The implication of reference in figure, 1, body, 2, air inlet, the 3, first valve, 4, gas outlet, the 5, second valve, 6,
