Description
Technical field
The present invention relates to a kind of pipeline connecting parts, particularly a kind of quick joint easy to loading and unloading.
Background technique
At present, much all adopt being connected between tube and tube, pipe and the valve to be threaded or flange plate connects, waste time and energy, very inconvenient, so people have developed ready-packaged joint.
As CN101526162B, a kind of " two-way sealing pull-off resisting plug-in type rapid joint " disclosed, comprise joint body, lock nut, elastic pawl and O RunddichtringO; Joint body hollow, be provided with the body connecting port at joint body one end, be provided with the locking outside thread in outside, body connecting port, on the locking outside thread, lock nut is housed, in the body connecting port, elastic pawl is housed, between elastic pawl and inside, body connecting port, the O RunddichtringO is housed.
But its elastic pawl and lock nut are absolute construction, and the elastic pawl front end does not have positioning device, only depend on the conical surface that matches to compress the location, the easy and pipeline generation displacement of ratchet in use, thus leak, the ready-packaged joint that has can be established a location card at the elastic pawl front end, but if this location card of neglected loading, then also this type of leakage can take place, and elastic pawl and lock nut are separate structure, need distinguish during installation successively and install, assemble loaded down with trivial details; The ready-packaged joint that has is made as integrative-structure with ratchet and lock nut, can prevent seepage because of ratchet and pipeline generation displacement generation, but pipeline can be followed lock nut and rotated when mounted, thereby causes that sealing effect is bad, pipeline clamps not strongly admittedly, causes leakage problems equally.
The ready-packaged joint that has is not provided with seal ring with pipeline enclosure in the body connecting port, use easy to leak repeatedly, and the ready-packaged joint that has adopts the seal ring one-way sealing, has the problem of easy to leak equally; The ready-packaged joint that has is not provided with pipe clamp in its body connecting port, when pipeline bowlder not, easily produce the phenomenon of leaking.
At the other end of joint, be provided with the outside thread that is used for connecting tube and valve body, generally all adopt the raw meal belt sealing, labor intensity is big, and efficient is low, and tension is easy to crack, crosses loose easy to leak, installation personnel is required high.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of rational in infrastructure, the anti-leak performance is good, a kind of quick joint easy to loading and unloading conveniently installed and used.
Purpose of the present invention is achieved through the following technical solutions: a kind of quick joint easy to loading and unloading, it comprises joint, lock nut, movable ratchet and pipe clamp, the two ends of joint are equipped with outside thread, one end of joint is provided with the body connecting port, lock nut is equipped with in the outside of body connecting port, the inwall of body connecting port is provided with a tilted conical surface A, one end of lock nut is provided with the internal thread that matches with joint, on the inwall of the lock nut the other end, begin to be provided with two next-door neighbours' annular groove from its end, be respectively groove A and groove B, the external diameter of groove A is provided with movable ratchet greater than the external diameter of groove B in the groove B, movable ratchet is a hollow structure, its exterior edge face is tilted conical surface B, and tilted conical surface B matches with tilted conical surface A, and the internal surface of movable ratchet is provided with several ratchets, the end that movable ratchet cooperates with groove B is provided with an annular shirt rim, be provided with the close-fitting end cap with groove A in the groove A, the end cap center is provided with through hole, end cap with the shirt rim activity orientation in groove B.
One O type silica gel sealing ring A is housed between described movable ratchet and the inside, body connecting port.
Described body also is provided with a pipe clamp in the connecting port.
It is that orthohexagonal six planes surround by the cross section perpendicular to the lock nut axis that described lock nut is provided with annular groove one end outer wall, and lock nut the other end outer wall is provided with the straight burr decorative pattern.
The other end end that described joint is relative with the body connecting port is provided with a cylindrical hollow bump, and bump is provided with an O type silica gel sealing ring B.
Described ratchet is provided with two～eight.
The present invention has the following advantages:
1, movable ratchet of the present invention is provided with ratchet, movable ratchet and lock nut are the prepackage integrative-structure, conveniently install and use, and adopt this structure to make that movable when mounted ratchet can not take place relative to circumferentially rotating with pipeline, movable ratchet is only done with respect to pipeline and is axially fed motion, sealing effect is better like this, and loading and unloading can not influence airtight quality repeatedly.
2, lock nut of the present invention is the double-purpose nut, by manual direct control, is locked by spanner when being processed as convenient locking of part of hexagon nut when the part that outer surface is processed with the straight line decorative pattern allows when required sealing load little or prepackage nut.
3, joint is provided with an O type silica gel sealing ring B with respect to the bump of the other end of body connecting port, and convenient connected valve body or pipeline are realized directly sealing, need not adopt extra seal approach.
4, the inner multidirectional sealing of O type silica gel sealing ring A of installing in body connecting port, good leak-proof effect, safe and reliable, durable in use.
5, be provided with pipe clamp, can proofread and correct, keep the circularity of pipeline.
