The lower surface of handle 14 is fixedly connected with the upper surface of snap-gauge 15.
In the present embodiment, by setting shaft 131 and bearing 132, so that pressing down on handle 14 in worker makes snap-gauge
15 stick into after card slot 16, and swing handle 14 makes handle 14 that shaft 131 be driven to rotate in bearing 132, and then passes through snap-gauge
15 drive threaded posts 8 to rotate so that threaded post 8 is moved down with ovable valve stem 9 so that valve rod 9 drive flap 10 to
Through-hole 4 is blocked in lower movement.
Further, the outer surface of shaft 131 is socketed with spring 17, the top and bottom end of spring 17 respectively with handle 14
Lower surface is fixedly connected with the upper surface of bearing 132.
In the present embodiment, by the way that spring 17 is arranged, so that after swing handle 14 drives flap 10 to block through-hole 4, pine
The pressing to handle 14 is opened, makes the elongation of spring 17 that handle 14 be driven to move up under the elastic reaction of spring 17, thus band
Dynamic snap-gauge 15 is detached from card slot 16, so that flap 10 will not be driven to rotate when worker accidentally encounters handle 14, and then avoids
The problem of handle 14 leads to gas leakage is accidentally touched when worker's maintenance work.
Further, flap 10 is specially round table-like, the diameter of through-hole 4 flap 10 maximum diameter and minimum diameter it
Between.
In the present embodiment, by the way that the diameter of through-hole 4 is arranged between the maximum diameter and minimum diameter of flap 10, so that
When swing handle 14 drives flap 10 to move down, flap 10 can be blocked through-hole 4, so as to by gas pipeline and valve
The isolation of body 1 is come.
Further, the one side that flap 10 is contacted with through-hole 4 is provided with gasket.
In the present embodiment, gasket is arranged by the one side contacted in flap 10 with through-hole 4, so that in swing handle 14
It drives flap 10 to move down when blocking through-hole 4, comes so that valve body 1 and gas pipeline be completely cut off.
Further, the surface on 8 top of threaded post offers card slot 16, and 15 lower surface of snap-gauge and 16 inner sidewall of card slot paste
It closes.
In the present embodiment, by setting snap-gauge 15 and card slot 16, so that when carrying out maintenance work to valve body 1, Gong Renke
Move down slide bar 12 with moving slide-bar 12 by squeeze grip 14, and then snap-gauge 15 is driven to stick into card slot 16, then turned
To handle 14, so that handle 14 drives threaded post 8 to rotate, and then drives flap 10 to move down and blocks through-hole 4, then
No longer squeeze grip 14 makes spring 17 that handle 14 be driven to move up, so that snap-gauge using the elastic reaction of spring 17
15 are detached from card slot 16, and the problem of handle 14 drives flap 10 to rotate accidentally is touched so as to avoid worker.
The working principle and process for using of the utility model: it after the utility model installs, is needing to carry out valve body 1
When upkeep operation, worker's squeeze grip 14 moves down handle 14 with moving slide-bar 12, and then snap-gauge 15 is driven to move down
So that snap-gauge 15 sticks into card slot 16, then goes to handle 14 and make handle 14 that shaft 131 be driven to rotate, and then pass through snap-gauge 15
Threaded post 8 is driven to rotate, so that threaded post 8 drives flap 10 to move down while rotation by valve rod 9, so that flap
10 block through-hole 4, so as to which valve body 1 and gas pipeline isolation are come, then no longer squeeze grip 14, due to spring 17
Elastic reaction make spring 17 drive handle 14 move up, and then drive snap-gauge 15 move up be detached from card slot 16, thus
The upkeep operation to valve body 1 can be carried out, squeeze grip 14 makes snap-gauge 15 stick into card slot 16 after upkeep operation is completed, and anti-
Handle hand 14 drives flap 10 to move upwardly so that flap 10 no longer blocks through-hole 4.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
