Description:
Performance requirements:
Temperature resistance, under the nominal pressure, the use of the
area of the valve temperature is divided into: general area of
-20~60 degrees Celsius. In the allowable temperature range, should
not leak.
Durability, under the nominal pressure, the valve structure for the
diaphragm structure, the whole trip open and close 1000 times, the
other structure of the valve full stroke open and close 4000 times,
there should be no leakage and other anomalies.
Safety device action, the safety device should be in the range of
1.2-1.5 times the nominal pressure action.

Structure:
1.Oxygen bottle valve is a valve to control the oxygen in and out
of the oxygen bottle.
2.Valve type bottle valve structure is mainly composed of a valve
body, a sealing washer, nut,
hand wheel, valve switch, the valve is composed of the reputation,
and the safety device and so on.
3. In addition to the handwheel, and piece, gasket, known more than
are made of brass or bronze
and pressing machine processing. In order to make the bottle mouth
and bottle valve tight according
to Fitch, the end of the valve body and the oxygen bottle with the
machined taper pipe thread,
by rotating horizontal cylinder mouth, the valve outlet, processed
into setting thread, used to
connect the regulator.
