Section is arc shape.The purpose being arranged in this way is to influence pressurization of the plug in air inlet pipe fitting by medium, medium convergence
In air reservoir, plug can be made to press closer and form sealing on leaning seat.
In above-mentioned gas valve, the elastic reset structure includes having spring in the looping pit of the leaning seat
Seat, is provided with spring, and one end resilient abutment of the spring is in the spring between the spring base and the plug
On seat, the medium position of the spherical outside surface of the other end of the spring and the plug is connected.When Spool rotating is opened, bullet
Property resetting structure work, which, which opens plug, makes plug and leaning seat there are spacing, this gas valve normal ventilation uses.
In above-mentioned gas valve, adapter is also threaded on the outlet pipe fitting, and the adapter is outer
End face has the oblique interconnecting piece for connecting with pipeline.The purpose being arranged in this way is when using gas-tpe fitting to dock with escape pipe
Sealing performance is more preferable, and safety is higher.
In above-mentioned gas valve, also have on the valve body and adjust runner, the valve rod is threaded through the tune
It throttles in road, connection ring is fixed on the outer wall of the adjusting runner lower end, is covered on the outer wall of the adjusting runner upper end
Equipped with upper cover, axial bolts are fixedly connected between the upper cover and the connection ring.The purpose being arranged in this way is to make valve body
It is more stable during installation, guarantee the normal use of this gas valve.
Compared with prior art, the advantages of this gas valve are as follows: structure is simple, in spool valve body, can make air inlet pipe
Air passage locking, highly-safe, long service life again in connector, it is easy for installation, stability is high.
