Self-closing valve valve in stuffiness is to maintain long-term closed mode, and in ventilation, valve needs manually to lift, then
Valve can be kept it turned on.
The operation principle of the present embodiment is as follows：
The realization principle of valve opening：Open and lift draw ring 13 manually, drive and reset cap 16, diaphragm 12, disk 10, magnet
9th, pull bar 6 up moves together, while pull bar 6 can drive Rocker arm 5 to rotate, and Rocker arm 5 will promote slide bar 4 and sealing gasket 3 to turn left fortune
Dynamic, so as to realize opening valve flowing channel, now gas can be from runner by and filling space of the valve body diaphragm below 12.
How valve keeps long-term opening under regular operating pressures：
After gas filling valve body can in the upward atmospheric pressure formed below of diaphragm 12, now upward atmospheric pressure with downwards
Magnet 9 and supporting plate 7 between suction just balance, diaphragm 12, magnet 9, pull bar 6 can be maintained at open position, join therewith
Dynamic Rocker arm 5, litter 4, sealing gasket 3 equally can also be maintained at open position, therefore can realize and keep long-term opening.
Closing principle when air pressure is excessive：When atmospheric pressure is more than the suction between sucker 10 and magnet 9 upwards, due to magnet
9 are fixed on pull bar 6, and pull bar 6 can not be moved up by supporting plate 7 is spacing again, so when diaphragm 12 drive sucker 10 after
Continuous up to move, and magnet 9 is then down inhaled by supporting plate 7, magnet 9 drives pull bar 6 down to move, Rocker arm 5 also rotate with from
And drive litter 4 to be turned right with sealing gasket 3 and move closure valve flowing channel, realize closing function.
Atmospheric pressure is too small or closing principle when flow is excessive：
When atmospheric pressure is less than the suction between magnet 9 and supporting plate 7, magnet 9 drives pull bar 6 down to move and repeats to close above
Close action.
Wherein transmission parts slide bar 4 and pull bar 6 using working of plastics, Rocker arm 5 then using stainless steel punch forming,
Transmission parts are die forming, therefore homogeneity of product superperformance is stable.Transmission parts are resistant material simultaneously, so
Long-term stable operation can be realized, transmission parts are few in addition and are molded the conventional production process such as punching press so integral product cost
It is low.Screen pack 15 is housed on airintake direction in seal aspect valve body 1, can effectively prevent impurity iron rust from being influenceed into valve inner
Transmission and sealing effectiveness.
Specific embodiment of the utility model is the foregoing is only, but the technical characteristics of the utility model is not limited to
This, any those skilled in the art in field of the present utility model, all cover in this practicality newly by the change or modification made
Among the scope of the claims of type.
