Description

A kind of clamp hoop check valve

Technical field

This utility model relates to a kind of check-valves, more specifically, it relates to a kind of clamp hoop check valve。

Background technology

It is known that the check-valves applied on the market at present is typically all flange form check-valves。Its main operational principle refers to the mobility relying on medium itself, promotes flap to automatically turn on and closes, preventing the valve that medium flows backwards。When medium in valve is by prescribed direction flowing, flap is opened by the effect of medium power；During medium counter flow, because flap deadweight and flap are by the effect of medium opposite force, make flap closely sealed with the sealing surface of valve seat and close, reach to stop the purpose of medium counter flow。Flange check valve is to be undertaken installing by the pipeline of nut with controlled media flow being connected, and very loaded down with trivial details when mounted can spend supernumerary's power material resources, add the installation cost of valve。

Utility model content

The purpose of this utility model is to provide a kind of check-valves being easy to quick installation, quick dismounting。

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of clamp hoop check valve, including the valve body being made up of the first housing and the second housing that can dismantle mutually docking, the docking port of described first housing and the second housing is rounded, the docking port of described first housing and the second housing is splicing mutually the flange that the cross section being subsequently formed a circle outwardly convex is triangular in shape, described first housing and the second housing realize removably connecting by clip, described clip includes compressed part that is mutually symmetrical with and that be pressed on valve body, described compressed part is provided with the depression matched with described flange relative to the side of valve body, the surface of described depression is provided with elastic layer。

Pass through such scheme, by the valve body of check-valves being divided into the first housing and the second housing, and connected by the mode of clip, achieve dismounting and the agility installed, and the flange that cross section by arranging evagination at the docking port place of the first housing and the second housing is triangular in shape and the recesses being arranged in clip compressed part close, serve the anticreep effect after the first housing and the second housing are fixed by clip, make connection more stable, and by the setting of elastic layer, make the flange can be further compacted, at the sealing function by elastic layer can also be received compressed, play the effect of leakproof。

It is optimized for further: described clip also includes being photographed the articulated section of two compressed part one end and is located at the tight lock part of two compressed part other ends, the briquetting of the U-lag that described tight lock part includes being located therein in a compressed part and the tie down screw being articulated with in another compressed part, described tie down screw, with the use of there being nut, can proceed to or produce the U-lag of described briquetting in the switching process of described tie down screw。

Pass through such scheme, clip is by adopting one end hinged, the mode of other end locking, can be more quick when operation, and tight lock part is arranged to tie down screw that one end is hinged on tight lock part and the cooperation of the briquetting with U-lag, so that clip can carry tie down screw, need not operation in another small change part, and simple to operate, it is only necessary to rotation lock screw rod is in the U-lag of briquetting, and then rotating nut just can realize fastening。

It is optimized for further: described nut is wing nut。

By such scheme, by nut is arranged to wing nut, thus improving operation ease, it is possible to directly manually twisting wing nut just can by locked clip device, it is not necessary to additionally look for spanner。

It is optimized for further: the section of the docking port between described first housing and the second housing is equipped with seal groove。

By such scheme, by being arranged on the seal groove on the docking port between the first housing and the second housing, it is possible to add sealing ring inside seal groove again, thus increasing the overall tightness of the valve body of this check-valves。

In sum, this utility model has the advantages that by the valve body of check-valves is divided into the first housing and the mode of the second housing, and material clip dismounts, it is achieved that check-valves fast dismount performance, it is simple to change and repairing；And by being arranged on coordinating of flange on the docking port of the first housing and the second housing and the depression in the compressed part of clip, considerably increase the clip connectivity robustness to valve body。

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail。

This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in right of the present utility model。

Embodiment, referring to accompanying drawing 1, state diagram when valve body being fixed for clip 3, concrete structure is referring to accompanying drawing 2 and accompanying drawing 3, valve body includes the first housing and the second housing, docking port at the first housing and the second housing is splicing mutually the flange 4 that the cross section being subsequently formed a circle outwardly convex is triangular in shape, accordingly, the compressed part 31 of clip 3 also is provided with the depression 311 matched with flange 4, thus after valve body is locked by clip 3, flange 4 will sink in depression 311, serve the anticreep effect after the first housing and the second housing are fixed by clip 3, make connection more stable；And in depression 311, it is additionally provided with elastic layer 8 so that flange 4 can be further compacted, at the sealing function by elastic layer 8 can also be received compressed, plays the effect of leakproof。

Refer again to Fig. 2, the section of the docking port between the first housing and the second housing is equipped with seal groove 5, cross the seal groove 5 on the docking port being arranged between the first housing and the second housing, it is possible to add sealing ring inside seal groove 5 again, thus increasing the overall tightness of the valve body of this check-valves。

When operating this clip 3 formula check-valves, can first by the first housing and the second housing to connecting, then at its peripheral set front band 3, flange 4 is made to be absorbed in the depression 311 of clip 3, then, upset clamping screw so that clamping screw snaps in the U-lag of briquetting 312, then the tight wing nut 7 of direct hand-screw, it is achieved the effect of Fast Installation。
