Abstract
The utility model discloses a gas returning port with convenient installation and no potential safety hazard, which comprises an adapter seat, wherein a spring seat is movably arranged in an inner chamber of the adapter seat, a jacking rod movably penetrates the spring seat, a valve top is arranged at the top of the jacking rod, a spring is sleeved on the jacking rod, and a limiting seat is arranged behind the spring seat in the inner chamber of the adapter seat through threads. The adapter seat of the utility model adopts an integrated structure, greatly facilitates the installation of the whole gas returning port, eliminates leaking points, and ensuring the safety of the gas returning port.
Description
Technical field
The utility model relates to gets back to return-air mouth in the storage tank with the gas of residue in the gas cylinder or self gasification.
Background technique
Gas cylinder is being carried out in the topping up process, and the gas of residue or self gasification can make the pressure in the gas cylinder constantly raise in the gas cylinder, when the pressure in the gas cylinder surpasses pressure in the storage tank, just can't continue topping up to gas cylinder; For this reason, just the gas of residue in the gas cylinder or self gasification need be discharged, if the directly emptying of the gas of discharge certainly will cause the wasting of resources, moreover some inflammable gas is not allow direct emptying.Therefore, allowing this part gas get back in the storage tank by the return-air mouth, both avoided the wasting of resources, avoided environmental pollution again, is to kill two birds with one stone.The return-air mouth that uses is installed cumbersome now; And, because its stub (tube) is assembled by two parts, during installation,, thereby cause leakage because often misoperation makes the attaching nut loosening, there is potential safety hazard, make the Security of return-air mouth can not get reliable guarantee.
The model utility content
Technical problem to be solved in the utility model is: a kind of easy for installation, return-air mouth of not having potential safety hazard is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the return-air mouth, comprise: stub (tube), be movably set with spring seat in the inner chamber of stub (tube), activity is equipped with push rod in the spring seat, the top of push rod is provided with the valve top, is set with spring on the push rod, and the back at spring seat in the inner chamber of described stub (tube) also is provided with position limit socket by screw thread.
Back at position limit socket in the inner chamber of described stub (tube) also is provided with jump ring.
The beneficial effects of the utility model are: stub (tube) of the present utility model adopts integral structure, greatly facilitates the installation of whole return-air mouth, has eliminated leakage point, has guaranteed the Security of return-air mouth.
