Embodiment
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
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 are set
There is handwheel, valve rod 1 inserts bonnet 2, and bonnet 2 is fixedly connected by bonnet body with valve seal, the valve between handwheel and bonnet 2
Air bag 3 is cased with bar 1, sets air-source inflow passage and source of the gas outlet passageway, the air inlet and exhaust of air bag 3 to pass through electricity on air bag 3
Magnet valve is realized；It is respectively arranged with the upper and lower surface of air bag 3 and air bag 3 is pressed into lid 4 and air-bag base 5 on the air bag of folder, on air bag
Lid 4 and air-bag base 5 are fixed by screws on air bag 3, are provided with the power transmission shaft 6 of through its center on lid 4 on air bag,
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 cunning on air-bag base 5
Air bag 3 is cased with outside dynamic installation, power transmission shaft 6 and mobile sleeve pipe 7, when air bag 3 inflate two similar in power transmission shaft 6 and movement sleeve pipe 7
Individual end face has spacing, and the spacing is stroke when valve is opened；The spring seat of honour is fixed with the top of the described inner chamber of bonnet 2
9, 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, it is slidably matched between the spring seat of honour 9 and valve rod 1, the spring seat of honour 9 and bullet
Spring 10 is additionally provided with spring between 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
It is equipped with multiple sealings.
Further, anti-extrusion sleeve pipe 14 is cased between described power transmission shaft 6 and the adjacent termination of mobile sleeve pipe 7, it is anti-extrusion
Air bag 3 is cased with outside gland pipe 14, the length value of anti-extrusion sleeve pipe 14 is smaller than the height value of air bag 3.
In the present embodiment, support ring is provided between described stuffing-box 11 and air-bag base 5, support ring one end withstands on gas
