Connecting hole is connected with locking piece, with locking two valve group safety lockset.Concrete, the second of the first locking closure 1
Side is the side relative with the first side of the first locking closure 1, and the second side of the second locking closure 2 is and
The side that the first side of two locking closures 2 is relative.By respectively in the second side and second of the first locking closure 1
Connecting hole is set on the second side of locking closure 2, and by locking piece through connecting hole, thus realize two valves
Two valve groups are locked in two valve group safety locksets, prevent two valve groups from opening by the blocking function of group safety lockset
Mouth end directly sprays compressed gas in outside atmosphere, causes security incident.
Further, the first overhanging flat board 6 also can be set on the second side of the first locking closure 1,
The second overhanging flat board 7 is set on the second side of the second locking closure 2.
Wherein, the first flat board 6 is provided with at least one first lockhole 61；Second flat board 7 is provided with at least
One the second lockhole 71, the first lockhole 61 and the second lockhole 71 are symmetrical to form connecting hole.Use
Time, the first lockhole 61 and the second lockhole 71 can be each passed through by locking piece, it is achieved to two valve group safety
The locking of lockset, and optionally, this locking piece can be lock 8.
Preferably, the quantity of above-mentioned first lockhole 61 and the second lockhole 71 is 3.
Further, also rubber blanket can be respectively provided with on the contact surface of the first locking closure 1 and the second locking closure 2,
I.e. surround the edge of cavity at the first locking closure 1 and the second locking closure 2 and be respectively provided with rubber gasket, Qi Zhongye
Including the first groove 4 and the second groove 5, so that the first locking closure 1 and the second locking closure 2 realize being tightly connected.
So that when two valve groups are locked in two valve group safety locksets, the stop needle valve in two valve groups because of
After mechanical breakdown or the reason such as aging are unlocked, in can being prevented effectively from two valve groups, gas directly leaks to air
In, cause security incident, be conducive to safety in production.
The present embodiment provide two valve group safety locksets, by setting have symmetrical structure the first locking closure and
Two valve groups are locked in the cavity being made up of the first locking closure and the second locking closure by the second locking closure, can be the most anti-
The only impulse channel blockage of two valve groups, it is to avoid the two open-ended oil gas of valve group are directly let out and are exposed on the external in air,
Cause security incident, improve the safety of two valve groups.
Last it is noted that various embodiments above is only in order to illustrate the technical solution of the utility model, and
Non-to its restriction；Although this utility model being described in detail with reference to foregoing embodiments, ability
The those of ordinary skill in territory is it is understood that it still can be to the technical scheme described in foregoing embodiments
