Serious gas leakage phenomenon is caused, there are serious security risk.
The content of the invention
The technical problem to be solved in the present invention is, there is provided a kind of anti-dropout valve body, it is intended to solve operating personnel and easily forget
The problem of quick coupling is extracted, produces security risk by note valve body.
The technical solution adopted by the present invention to solve the technical problems is：There is provided a kind of anti-dropout valve body, including tube body with
And valve and the handle of rotating valve installed in tube body one end, the other end of the tube body are equipped with steel ball, in the steel ball hole
The steel ball in tube body is stretched into equipped with a part；The valve body further includes the sliding sleeve of compressible steel ball and is provided for sliding sleeve
The elastic component of restoring force, the sliding sleeve are slidably set in outside tube body；When valve is in open mode, the slip
Sleeve compresses steel ball, and the handle supports the sliding sleeve；When valve is closed, the sliding sleeve can be to handle
One Slideslip of hand simultaneously unclamps steel ball.
Further, the tube wall is equipped with first boss, and the sliding sleeve is internally provided with for compressing steel ball
Second boss, the elastic component are compressed between first boss and second boss.
Further, the elastic component is spring.
Further, one end outer wall of the tube body installation sliding sleeve is equipped with the first card slot, is set in first card slot
There is the snap ring for preventing sliding sleeve from coming off.
Further, the inboard wall of tube body is further opened with the second card slot, and sealing ring is equipped with second card slot.
Further, the steel ball has three, and three steel balls are uniformly distributed around the tube body central axes.
Further, the sliding sleeve outer wall is additionally provided with the annular knurl of increasing friction force.
Further, the sliding sleeve is made of copper.
Relative to the prior art, a kind of anti-dropout valve body provided by the invention, in use, valve body is connected with quick coupling,
And quick coupling is pinned by steel ball.When valve is in open mode, the sliding sleeve compresses steel ball, and handle is supported described
Sliding sleeve；When valve is closed, the sliding sleeve to one Slideslip of handle and can unclamp steel ball.So operate
Member cannot unlock quick coupling by mobile sliding sleeve, can effectively avoid fast in the state of valve is not turned off
Before quick coupling is extracted, forget to close valve, so as to cause the security risks such as leakage.
Brief description of the drawings
Below in conjunction with accompanying drawings and embodiments, the invention will be further described, in attached drawing：
Fig. 1 is the schematic cross-sectional view of anti-dropout valve body provided by the invention；
Fig. 2 is the decomposition diagram of anti-dropout valve body；
Fig. 3 is the schematic cross-sectional view that anti-dropout valve body coordinates with quick coupling.
Embodiment
In conjunction with attached drawing, elaborate to presently preferred embodiments of the present invention.
As illustrated in fig. 1 and 2, the present invention provides a kind of anti-dropout valve body 100, including tube body 10 and installed in tube body 10 1
The valve (not shown) at end and the handle 20 of rotating valve.The other end of tube body 10 is equipped with steel ball 11, and one is equipped with steel ball hole 11
The steel ball 30 in tube body 10 is stretched into part.Valve body 100 further includes the sliding sleeve 40 of compressible steel ball 30 and is sliding sleeve 40
The elastic component 50 of restoring force is provided, sliding sleeve 40 is slidably set in outside tube body 10.Such as Fig. 3, in use, valve body 100 with
Quick coupling 200 connects, and pins quick coupling 200 by steel ball 30.When valve is in open mode, sliding sleeve 40 is pressed
Tight steel ball 30, handle 20 support sliding sleeve 40；When valve is closed, sliding sleeve 40 can break away to handle 20 1
Move and unclamp steel ball 30.So operator is that cannot be solved by mobile sliding sleeve 40 in the state of valve is not turned off
Quick coupling 200 is locked, before effectively avoiding quick coupling 200 from extracting, forgets to close valve, so as to cause the safety such as leakage hidden
Suffer from.
In the present embodiment, elastic component 50 is spring.10 outer wall of tube body is equipped with first boss 12, is set inside sliding sleeve 40
It is useful for compressing the second boss 41 of steel ball 30, elastic component 50 is compressed between first boss 12 and second boss 41.When with outer
Power by sliding sleeve 40 to handle 20 move when, elastic component 50 is compressed, when decontroling sliding sleeve 40, elastic component 50 promote slide
Moving sleeve 40 resets.
Further, one end outer wall of the installation of tube body 10 sliding sleeve 40 is equipped with the first card slot 13, is set in the first card slot 13
There is the snap ring 60 for preventing sliding sleeve 40 from coming off.So elastic component 50 can be avoided to release sliding sleeve 40 outside tube body 10, caused
Sliding sleeve 40 comes off.
Specifically, 10 inner wall of tube body is further opened with the second card slot 14, and sealing ring 70 is equipped with the second card slot 14.When fast quick access
In first 200 insertion tube body 10, sealing ring 50 can prevent the gap of gas or liquid between tube body 10 and quick coupling 200 from letting out
Leakage.
In the present embodiment, steel ball 30 has three, and three steel balls 30 are uniformly distributed around 10 central axes of tube body, so can be steady
Fixed pinning quick coupling 200, avoids quick coupling from rocking.40 outer wall of sliding sleeve is additionally provided with the annular knurl 42 of increasing friction force.
Sliding sleeve 40 is made of copper, and can also be made certainly of metals such as stainless steel, aluminium.
In conclusion a kind of anti-dropout valve body provided by the invention, is to pass through in the state of valve is not turned off
Sliding sleeve 40 is moved to unlock quick coupling, only after rotating handles 20, could be solved by mobile sliding sleeve 40
Quick coupling is locked, before effectively avoiding quick coupling from extracting, forgets to close valve, so as to cause the security risks such as leakage.
It should be appreciated that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations, to ability
