The technological scheme that the problem that the utility model is the above-mentioned proposition of solution adopts is:
A kind of gas stop valve of oxygenerator, valve body 1 left end offers suction port 2, valve body 1 right-hand member sets out gas port 3, valve body 1 inside arranges valve seat 4, valve body 1 top arranges valve gap 5, valve rod 6 lower end is passed valve gap 5 and is stretched into valve body 1 inside, valve rod 6 lower end arranges flap 7, flap 7 arranged outside sealing gasket 8, sheathed spring 9 on valve rod 6, spring 9 lower end is pressed on the upside of valve gap 5, valve rod 6 upper end arranges pressing plate 10, spring 9 upper end is pressed on the downside of pressing plate 10, vertical bar 11 is symmetrical arranged on the upside of valve gap 5, vertical bar 11 is positioned at spring 9 surrounding, left, between right adjacent vertical bar 11, horizon bar 12 is set, round rectangle briquetting 13 by bearing pin A14 and horizon bar 12 hinged, depression bar 15 is set on the upside of round rectangle briquetting 13, between adjacent vertical bar 11, upper end arranges connecting rod 16.
Described flap 7 is frustoconic shape metal flap, and structural strength is large, long service life.
Described spring 9 is Compress Spring, has good compression performance.
Arrange bearing pin B17 between described forward and backward adjacent vertical bar 11, bearing pin B17 is positioned at above horizon bar 12, for pressing down the position limiting depression bar after flap stops ventilation.
Described depression bar 15 upper end arranges grip 18, is convenient to grasp.
Working principle of the present utility model: when air-suction state, spring is in diastole state, flap is positioned at above valve seat; Need to rotate depression bar to the left or to the right when stopping air feed, depression bar drives round rectangle briquetting half-twist, round rectangle briquetting presses down valve rod makes flap and valve seat close, and now spring is in compressive state, on the upside of the depression bar then making bearing pin B be arranged on now to be in level.
The beneficial effects of the utility model are: 1, structure is simple, are convenient to safeguard, solve common stop valve and cause screw mandrel serious wear owing to often using, easily produce the problem of stripped thread.2, flap is frustoconic shape metal flap, and structural strength is large, long service life.3, spring is Compress Spring, has good compression performance.4, arrange bearing pin B between forward and backward adjacent vertical bar, bearing pin B is positioned at above horizon bar, for pressing down the position limiting depression bar after flap stops ventilation.5, depression bar upper end arranges grip, is convenient to grasp.
