Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, the utility model provides a valve combination quick connection mechanism, which comprises two arc pipe clamps 1, wherein the two pipe clamps 1 are mutually matched to form an annular clamping piece sleeved on a pipe fitting; every curved pipe strap 1 all is equipped with the link of two relative settings, and the link is connected the fastening through the bolt.

Referring to fig. 2 and 3, the quick connection mechanism further comprises a sealing ring 2 located in a sealing groove inside the clamping member, wherein the sealing ring 2 is connected with the connecting ends of the two pipelines and plays a role in sealing after the two pipelines are connected; the two ends of the sealing ring 2 are smoothly bent inwards along the insertion direction of the pipeline to form a bent angle 21, the bent angle 21 has a preset height b relative to the inner annular surface of the sealing ring 2, and the preset height b is 2-6mm in the utility model; the diameter of the interior anchor ring of sealing washer 2 is greater than the pipe fitting external diameter, the utility model discloses in, the diameter of the interior anchor ring of sealing washer 2 is greater than pipe fitting external diameter 1-3 mm.

Referring to fig. 3, in the application process of the seal ring 2, if the pipe fitting on one side of the seal ring 2 is inserted into the seal ring 2 from the direction a, since the diameter of the inner annular surface of the seal ring 2 is larger than the outer diameter of the pipe fitting, and the bend 21 has deformation performance, the pipe fitting can be inserted into the seal ring 2 very easily and quickly; in the same way, the pipe fitting on the other side of the sealing ring 2 can be quickly and conveniently inserted into the sealing ring 2. Simultaneously, all exert external force to outer anchor ring a week of sealing washer 2, make the anchor ring of whole sealing washer 2 compress tightly to the pipe fitting on, the anchor ring of sealing washer 2 can play certain sealed effect, in addition, when the anchor ring of sealing washer 2 compresses tightly to the pipe fitting on, the inside bent angle 21 of sealing washer 2 can be inseparabler laminate to the pipe fitting on, the sealed effect that plays that bent angle 21 can be better.

Fig. 1-3 show an embodiment of a one-way valve, and with continued reference to fig. 7, in use, one end of the sealing ring 2 is first quickly clamped to the connecting end 31 of the valve 3, and then the two pipe clamps 1 are assembled together, so as to keep the bolts at the connecting end loose to some extent. In the use of user, need not to assemble sealing washer 2 and two pipe strap 1 again, only need with the link plug of pipe fitting 4 to the other end of sealing washer 2, it can to screw up the bolt again. In the bolt screwing process, the two pipe clamps 1 are fastened to form an external force of one circle of the outer ring surface of the sealing ring 2, the inner ring surface of the sealing ring 2 and the bending angle 21 are pressed onto the pipe fitting, and the sealing performance is guaranteed. The inventor verifies through many times of experiments that the utility model discloses a quick connecting mechanism can guarantee the inside 2.5-5 MPa's of pipe fitting pressure, can reach the national standard requirement.

The utility model has the advantages that the sealing ring 2 with the inner ring surface diameter larger than the outer diameter of the pipe fitting is arranged, so that the quick-inserting function is realized between the sealing ring 2 and the pipe fitting 4, and the installation of the sealing ring 2 is simpler; the sealing ring 2, the two pipe clamps 1 and the valve are assembled without being disassembled, the pipe fitting 4 and the valve can be taken as a whole, the pipe fitting 4 and the whole are assembled only by inserting the pipe fitting 4 into the sealing ring 2 and then screwing the bolt, and the assembling process is simple, convenient and quick.

In order to further ensure the sealing performance of the quick connecting mechanism, in the utility model, the pipe clamp 1 is a semi-ellipse with deformation function, and the two pipe clamps 1 are mutually matched to form a complete ellipse clamping piece; each semi-elliptical pipe strap 1 is provided with two connecting ends respectively located at opposite ends of the elliptical clamping member in the length direction, i.e., referring to fig. 4, the two connecting ends of each semi-elliptical pipe strap 1 are respectively located at the c and d ends, but not at the e and f ends.

Because oval chucking spare is flat long, when assembling two pipe strap 1 to the outside of sealing washer 2, it is more convenient. In addition, because two pipe clamps 1 have the deformation function, when fastening through the bolt, pipe clamp 1 can take place deformation, becomes the identical shape with pipe fitting 4, and the inventor verifies through many times of experiments that oval-shaped chucking spare is more favorable to the leakproofness of sealing washer 2.

In order to further improve the pressing capability of the clamping piece consisting of the two pipe clamps 1 on the sealing ring 2, improve the sealing performance of the sealing ring 2 and avoid the leakage of the conveying medium in the pipe fitting 4, referring to fig. 2, it is preferable that both connecting ends of one pipe clamp 1 are provided with tongue pieces 11, and the other pipe clamp 1 matched with the two pipe clamps is provided with tongue grooves into which the tongue pieces 11 are inserted.

Referring to fig. 6-7, as another embodiment, the quick-connect mechanism of the present invention can be used in a two-way valve, and the quick-connect mechanism for the two-way valve comprises two clamping members, each of which is provided with a sealing ring 2. Referring to fig. 8, the utility model provides a quick connect mechanism can be used to on tee bend or the four-way valve for quick connect mechanism on tee bend or the four-way valve includes three or four chucking spare, all is equipped with sealing washer 2 in every chucking spare. When chucking spare is two, three or four, be located a plurality of pipe strap 1 of homonymy and can connect as an organic wholely, make two adjacent chucking spare sharing link, save the bolt quantity.

To sum up, the utility model discloses a set up the sealing washer that the diameter is greater than the pipe fitting external diameter in the inside of chucking spare, the sealing washer can be pegged graft the link of the valve that needs to connect or the pipe fitting by user's one hand, and the link of valve or pipe fitting is fastened to the sealing washer to the rethread chucking spare, and the inside bent angle of sealing washer plays sealed effect, and the user need not to dismantle parts such as valve, chucking spare and sealing washer when using, and the pipeline that directly will connect is pegged graft above-mentioned assembled structural can, realizes inserting the function soon. To sum up, the beneficial effects of the utility model are that: simple structure, the valve combination process is simple and easy convenient, and the user need not to be hard can realize pegging graft fast between valve and the pipe fitting, and the degree of difficulty is less, and saves user's time.
