Description
Technical field
The utility model relates to a kind of quick-detachment connection valve.
Background technique
The Placement of existing equipment on pipeline generally adopts connecting tube to connect, and valve is set on connecting tube, to realize the break-make of medium channel, the defect that this Placement exists is complicated structure on the one hand, the turnover two ends of valve all obtain to arrange separately and connect short tube and corresponding reducer pipe etc., two is operation more complicated, needs special throttle down during device maintenance.
Model utility content
In order to overcome the above-mentioned defect of prior art, the utility model provides a kind of quick-detachment connection valve, and this connection valve can be used for the connection on pipeline, structure is simple, need not water source be closed during maintenance, just can directly the part needed repairing be split out from pipeline, very convenient and practical.
The technological scheme that the utility model adopts: a kind of quick-detachment connection valve, it is characterized in that comprising the left body of docking mutually and right body, a described left side, the joint cover of right body has sleeve pipe, described sleeve pipe respectively with a described left side, right body is fixedly connected with in releasable connection mode, the inwall of described sleeve pipe and a described left side, Sealing is equipped with between right body, a described left side, respective elastic force normally close valve is respectively equipped with in right body, lay respectively at a described left side, two in right body described elastic force normally close valves are oppositely arranged, described elastic force normally close valve comprises the flap that can move axially and forms the valve seat of sealing pair with described flap, described valve seat is positioned at the axially inner side of described flap, described valve seat is provided with the sealing surface of seat of the annular matched with the sealing surface of described flap, and be provided with the center through hole forming medium channel, the front end of described flap is provided with can through the axial extension of the center through hole of described valve seat, the axial length of described axial extension is the length that the front end of the described axial extension when this elastic force normally close valve is in closed condition exceeds the inner end face of related pipe body.
Working principle of the present utility model and beneficial effect are: the valve seat of elastic force normally close valve in two bodys under normal circumstances, flap, the pre compressed magnitude of spring and spring all should be identical, by a described left side, after right body becomes quick-detachment connection valve with sleeve-assembled, the front end, axial extension of the flap of described two elastic force normally close valves withstands on together, two flaps are pushed away corresponding valve seat separately, the distance pushed away equals front end, axial extension under valve seal pair closes (contact with each other and form sealing) state and surmounts the distance (when not considering relevant gap) of the inner end face of related pipe body, the elastic force normally close valve in two bodys is made to be in opening state, the medium channel of two bodys is communicated with, medium is allowed to flow in valve from the outer end port of arbitrary body, medium channel in valve flows out from the outer end port of another body, can by suitably arranging the described length of axial extension and the structure of other associated parts and size, suitable setting or the distance between adjustment flap and valve seat, to adapt to the parameter request to elastic force normally close valve aperture and resistance etc. under correlation circumstance.After being removed by arbitrary body, the elastic force normally close valve in two bodys all relies on self spring force to push flap to valve seat, cuts off the medium channel in body, realizes automatically closing.This quick detach connection valve is used for pipeline as connecting tube connect, such as one end connects liquid or gas pipeline, the import or export of the other end connection device, when the relevant device that needs repairing (or pipeline, lower same) time, the body directly connecting this equipment can be removed together with this equipment, or this body is removed separately (equipment that also just achieves thus is from the dismounting pipeline), the elastic force normally close valve be connected in another body on pipeline will cut out automatically, therefore without the need to arranging valve based on the object of maintenance and dismounting separately on corresponding connecting tube, the valve of Focus Control connecting tube MEDIA FLOW is not needed whether to close yet, after apparatus modifications is complete, to reinstall on sleeve pipe together with this equipment with this equipment connection body together, quick-detachment connection valve recovers on state automatically, be very easy to relevant operation thus.
