Kelly 42 is rotated, valve ball 2 can be driven to rotate, Open valve, when spring 41, which rebounds, to be restored, valve ball 2 is inverted, and valve is closed, card
It is detached between bar 42 and deck 43.
The handle 5 is fixedly connected with kelly 42, fixed by screw 51 between handle 5 and kelly 42, as peripheral operation people
When member's rotational handle 5, kelly 42 can be driven to rotate.
Such as Fig. 3 and Fig. 4, specifically, the deck 43 includes annular convex platform 432 and pilot sleeve 433, the annular convex platform 432
Pilot sleeve 433 is arranged in be coaxially disposed close to one end of valve rod 3, annular convex platform 432 and pilot sleeve 433,42 activity of kelly
It is arranged in pilot sleeve 433, annular convex platform 432 is symmetrically arranged with the flat slot 434 of 1/4 ring and card slot 435 close to one end of valve rod 3,
The opening of the flat slot 434 of 1/4 ring is equipped with the flat slot 434 of 436,1/4 ring of limited block and is connected with card slot 435, flat 434 He of slot of 1/4 ring
The depth of card slot 435 is different, and card slot 435 is deep compared with the flat slot 434 of 1/4 ring；Kelly 42 includes cylinder 421 and convex flat 422, convex flat
Cylinder 421 is arranged in close to one end of valve rod 3 in side 422, convex flat 422 respectively with the flat slot 434 of 1/4 ring, card slot 435 and limited block
436 match.Cylinder 421 is movably arranged in pilot sleeve 433, can be moved along the axis direction of pilot sleeve 433, in movement
In the process, when convex flat 422 is embedded in card slot 435, kelly 42 is not able to rotate, and valve is closed state at this time, when
When convex flat 422 is deeply embedded in card slot 435 again, kelly 42 is rotated at this time, and the convex flat 422 of kelly 42 can turn to 1/
In the flat slot 434 of 4 rings, the flat slot 434 of 1/4 ring is turned, convex flat 422 is limited the limit of block 436 and is not able to rotate, holding position, at this time
Valve is open state.It is equipped with protrusion 437 close to one end of valve rod 3 in annular convex platform 432, valve body 1 is equipped with the slot matched
Mouthful, which is embedded in notch, can limit the rotation of deck 43, be fixed on deck 43 in valve chamber 11.
Such as Fig. 5 and Fig. 6, the self-locking gas valve when in use, when the valve 4 is in a closed state, the convex flat 422 of kelly 42
It is stuck in the card slot 435 of deck 43, handle 5 is not able to rotate, and valve is lock state at this time, cannot be opened；When pressing handle 5,
Since handle 5 is fixedly connected with kelly 42, kelly 42 can be in the pilot sleeve 433 of deck 43 along 433 axis side of pilot sleeve
To movement, continuing to press handle 5, kelly 42 is driven to continue to move to, the convex flat 422 of kelly 42 is deeply embedded in card slot 435,
Rotational handle 5 at this time drive kelly 42 to rotate, and the convex flat 422 of kelly 42 rotates in the flat slot 434 of 1/4 ring, while kelly 42
The limit of fluting 32 of the elastic force and valve rod 3 of spring 41 is overcome to connect, handle 5 continues to rotate, and handle 5 drives kelly 42, kelly 42
Band ovable valve stem 3, valve rod 3 drives valve ball 2 to rotate, to realize the unlatching of valve, release handle 5 at this time, kelly 42 is in 41 bullet of spring
It is withstood under the action of power on the limited block 436 of deck 43, limited block 436 limits the opening angle of valve, and guarantees valve
Holding position is not moved in the on state, and spring 41 is in compressive state always.When needing to close valve, flicking handle 5 is simultaneously
It rotates backward, the convex flat 422 of kelly 42 inversely enters the flat slot 434 of 1/4 ring, and kelly 42 drives valve ball 2 with ovable valve stem 3, valve rod 3
Rotation, valve progressively close off, and since spring 41 is in compressive state always, spring 41 has an active force to kelly 42, with kelly
The convex flat 422 of 42 backwards rotation, kelly 42 is transferred to card slot 435, and kelly 42 is ejected under the elastic force effect of spring 41, extensive
Multiple valve-closed state.
