The emergency leaking stoppage device for the cylinder valve is good in leaking stoppage effects, safe and reliable, convenient to operate, easy to learn, beautiful and decent, comfortable in feeling, economic, long in service life and the like.
Description
Technical field
The utility model relates to the leakage-baffling device of cylinder valves such as chlorine, ammonia, sulfur dioxide, specifically is a kind of cylinder valve emergency leakage blocking device.
Background technique
Under normal circumstances, cylinder filling; After transporting, storing and use; Close cylinder valve, and tighten a hexagon nut sealing again, prevent the hazardous gas leakage in the cylinder valve outlet port.The technical problem that exists: use in the hazardous gas in reality, exist cylinder valve and can not close valve fully, and the cylinder valve outlet port is because of thread abrasion, hexagon nut can't effectively be tightened again, produces hazardous gas to leak; Based on above reason, must design as early as possible, produce a kind of novel effective, safety, reliable, easy to operate cylinder valve emergency leakage blocking device.
The model utility content
The purpose of the utility model; Be fundamentally to solve at cylinder valve to close fully, cylinder valve outlet thread abrasion, hexagon nut can not effectively be tightened again; Produce the technical barrier that hazardous gas is leaked, and safe and reliable, effective, easy to operate cylinder valve emergency leakage blocking device is provided.
The technological scheme of the utility model is achieved in that
A kind of cylinder valve emergency leakage blocking device; It is characterized in that: it comprises bench vice type bearing 1, no screw thread hexagonal sealed cap 2, gasket seal 3, tightens screw rod 4, special spanner 6; Central position on described bench vice type bearing (1) top is provided with screw mouth; Tighten on the screw mouth that screw rod 4 just is screwed in bench vice type bearing top, the bottom of tightening screw rod 4 connects no screw thread hexagonal sealed cap 2, and no screw thread hexagonal sealed cap 2 bottoms are provided with gasket seal 3.
Also be provided with inclined-plane, bottom and the concave surface that plays the location and prevent the out-of-flatness effect of the cylinder valve back side in described bench vice type bearing 1 bottom.
Said no screw thread hexagonal sealed cap 2 is tightened connection location in screw rod 4 locating slots with the employing positioning screwn 5 that is connected of tightening screw rod 4 through no screw thread hexagonal sealed cap minor thread hole screw-in, and said gasket seal 3 embeds bottom the no screw thread hexagonal sealed cap.
The utility model by turning clockwise, arrives cylinder valve exit face and no screw thread hexagonal sealed cap to force transmission with special-purpose wrench through tightening screw rod and bench vice type bearing central upper portion position screw-internal thread fit; Make cylinder valve exit face and no screw thread hexagonal sealed cap fastening, the crush seal pad makes the gasket seal distortion; Make the gap of gasket seal blanket gas cylinder valve exit face and no screw thread hexagonal sealed cap surface of contact, thereby play purpose, and it is good to have a plugging effect the emergency leakage blocking of cylinder valve hazardous gas leakage; Safe and reliable, easy to operate, easy to learn; Big device comfortable feel attractive in appearance, economical and practical, advantages such as long service life.
Description of drawings
Fig. 1 is the internal structure schematic representation of the utility model.
Embodiment
A kind of cylinder valve hazardous gas emergency leakage blocking device; It comprises bench vice type bearing 1, no screw thread hexagonal sealed cap 2, gasket seal 3, tightens screw rod 4, positioning screwn 5, special-purpose wrench 6; Be provided with the leak stopping chamber in bench vice type bearing 1 inside; Central upper portion position at described bench vice type bearing 1 is provided with screw mouth; Tighten screw rod 4 and just be screwed in the screw mouth place on top, leak stopping chamber, the bottom of tightening screw rod 4 connects no screw thread hexagonal sealed cap 2, and said no screw thread hexagonal sealed cap 2 adopts positioning screwn 5 to tighten in screw rod 4 locating slots connection through no screw thread hexagonal sealed cap minor thread hole screw-in being connected of screw rod 4 to locate with tightening; Described no screw thread hexagonal sealed cap 2 bottoms are provided with the combination plane that the cylinder valve pelvic outlet plane matches, and gasket seal 3 just is embedded on this combination plane.
When the utility model leaks in cylinder valve 7 hazardous gases; Position between the cylinder valve emergency leakage blocking device overlaps cylinder valve 7 therein; The back side that is enclosed within cylinder valve to the inclined-plane of emergency device bench vice type bearing 1 bottom and concave surface position again; Play the location; Prevent the irregular effect in the cylinder valve back side, the pelvic outlet plane central position that is enclosed within cylinder valve 7 to no screw thread hexagonal sealed cap 2 makes the combination plane of no screw thread hexagonal sealed cap 2 bottoms match with pelvic outlet plane, and this moment, gasket seal 3 was compressed in combining between the plane of cylinder valve 7 pelvic outlet planes and no screw thread hexagon nut 2 bottoms; Tighten screw rod 4 by turning clockwise with special spanner 6 and arrive the gasket seal between cylinder valve 7 pelvic outlet planes and no screw thread hexagonal sealed cap 2 bottom surfaces to force transmission; Extruding makes gasket seal distortion and cylinder valve 7 pelvic outlet planes and no screw thread hexagonal sealed cap 2 surface of contact is sealed, thereby plays the purpose to the emergency leakage blocking of gas cylinder hazardous gas, and it is good to the utlity model has plugging effect; Safe and reliable; Easy to operate, easy to learn, big device comfortable feel attractive in appearance; Economical and practical, advantages such as long service life.
Though foregoing has shown the detailed embodiment of the utility model, obvious, those skilled in the art revises and changes can carry out part under the prerequisite of model utility; The content of mentioning in the description accompanying drawing of preceding text is not as the restriction to the utility model only as illustrative case; Have a kind of cylinder valve emergency leakage blocking device of technical characteristics described herein, all fall into this patent protection domain.
