Embodiment
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to as described below：
Air bag stop valve, as depicted in figs. 1 and 2, including handwheel, valve rod 1, bonnet 2 and valve body, the upper end of valve rod 1 is provided with hand
Wheel, the insertion bonnet 2 of valve rod 1, bonnet 2 is fixedly connected by bonnet body with valve seal, the valve rod 1 between handwheel and bonnet 2
On be cased with air bag 3, air bag 3 setting air-source inflow passage and source of the gas outlet passageway, the air inlet and exhaust of air bag 3 pass through magnetic valve
Realize；It is respectively arranged with the upper and lower surface of air bag 3 and air bag 3 is pressed on the air bag of folder lid 4 on lid 4 and air-bag base 5, air bag
It is fixed by screws in air-bag base 5 on air bag 3, the power transmission shaft 6 of through its center is installed on air bag, in gas on lid 4
The mobile sleeve pipe 7 of through its center is installed, power transmission shaft 6 and mobile sleeve pipe 7 are enclosed on valve rod 1 and are to slide on capsule base 5
Install, be cased with air bag 3 outside power transmission shaft 6 and mobile sleeve pipe 7, power transmission shaft 6 is close with mobile sleeve pipe 7 when air bag 3 is inflated two
End face has spacing, and the spacing is stroke when valve is opened；The spring seat of honour 9 is fixed with the top of the described inner chamber of bonnet 2,
The spring seat of honour 9 is against on the stuffing-box 11 of bonnet 2, and the bottom of the inner chamber of bonnet 2 is placed with the spring lower seat 8 that can be slided therewith, and
Coordinated between spring lower seat 8 and valve rod 1 by unthreaded hole, be slidably matched between the spring seat of honour 9 and valve rod 1, the spring seat of honour 9 and spring
Spring 10 is additionally provided between lower seat 8.
Further, as shown in figure 3, being provided with hole slot at the described upper surface of stuffing-box 11, valve rod 1 passes through the hole slot, should
Hole slot is disposed with multiple packing seal elements 12 and filler pressing 13 from bottom to up, valve rod 1 through filler pressing 13 and both
Coordinated by unthreaded hole, the lateral surface of filler pressing 13 is provided with partial threads, is all provided between filler pressing 13 and valve rod 1 and stuffing-box 11
