Description

Weld-ring pipe clamp

Technical field

The utility model belongs to pipeline fixing device technical field, particularly relates to a kind of weld-ring pipe clamp.

Background technique

In current pipeline construction, mainly adopt for the mode that is fixedly connected with between pipeline and be threaded or the mode such as welding, the construction period is long, pipeline connection reliability is poor, maintenance difficulty large, connecting tube working pressure is low to utilize above-mentioned form of construction work generally to exist, generally bear pressure and be less than 5MPa, be therefore badly in need of a kind ofly connecting reliable, to bear the high and construction install convenience of working pressure linkage structure.

Model utility content

Technical problem to be solved in the utility model is: provide a kind of weld-ring pipe clamp, poor with the pipe connecting structure connection reliability solving existing use, bears the technical problem that working pressure is low.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of weld-ring pipe clamp, comprise the arc pipe clamp body linked together by fastening piece, the internal surface of described arc pipe clamp body is provided with the annular groove for holding seal ring, described pipe clamp also comprises two and connects ring body, described connection ring body is used for being fixedly connected with pipeline, and described connection ring body is arranged in the buckling groove in described arc pipe clamp body internal surface, and described buckling groove is positioned at the docking side of described arc pipe clamp body.

As improving further, described connection ring body is steel loop.

As improving further, described buckling groove opens wide to the inside.

After have employed technique scheme, the beneficial effects of the utility model are:

Owing to being provided with the buckling groove with connecting ring mates at the internal surface of arc pipe clamp body, by buckling groove and the axially locating that can realize arc pipe clamp body after corresponding connection ring body clamping, form very high join strength, bear pipeline Intermediate High Pressure, structure is simple, be easy to dismounting, in annular groove, use special pressure responsive sealing circle simultaneously, and the butt joint position that seal ring and two docks pipeline is corresponding, such manifold pressure makes seal ring tightly be attached on pipeline and forms sealing, sealing reliability is high, integral installation construction is simple, fast, be convenient to maintenance, antidetonation, resisted shrinkage expands.

Because connection ring body is steel loop, economical, energy-conservation, safety, health.

Because buckling groove opens wide to the inside, be convenient to processing, easy to install.

Embodiment

In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

Shown in common as shown in Figure 1 to Figure 4, a kind of weld-ring pipe clamp, comprise the arc pipe clamp body 1 linked together by fastening piece, the internal surface of arc pipe clamp body 1 is provided with the annular groove 3 for holding seal ring 4, pipe clamp also comprises two and connects ring body 5, connect ring body 5 for being fixedly connected with pipeline 6, connect ring body 5 and be arranged in the buckling groove 2 on arc pipe clamp body 1 internal surface, buckling groove 2 is positioned at the docking side of arc pipe clamp body 1.

Above-mentioned connection ring body 5 is steel loop, economical, energy-conservation, safety, health, and mounting cost connects overall cost than flange-type and saves about 30%, takes up space few simultaneously, only account for flanged 2/3rds after installing.

The concrete set-up mode connecting ring body 5 can according to the structural type of Fig. 3, being about to connect ring body 5 is fixed on the outer surface of pipe end by the mode of welding, certainly other means of fixation can also be adopted, what connect ring body 5 arranges the intensity that simultaneously can improve pipeline 6, and structural design is simple and reasonable.

Utilize buckling groove 2 and be connected after ring body 5 is connected, the axially locating between arc pipe clamp body 1 and two pipelines 6 can be realized, thus the connection realized between two pipelines, special pressure responsive sealing circle 4 is placed in annular groove 3 simultaneously between two buckling grooves 2, seal ring 4 is made to correspond to the butt joint place of two docking pipelines 6, utilize the internal pressure of pipeline 6 that seal ring is tightly attached on pipeline, thus complete sealing.

Wherein buckling groove 2 also can be set to following concrete structure, opens wide to the inside by buckling groove 2, adds like this and only produces a trough rim man-hour, is convenient to processing and installs.

As shown in Figure 4, pipe clamp connects the using state of two docking pipelines, wherein have employed three pipe clamps in Fig. 4 to connect two docking pipelines, during specific operation, now pressure response seal ring 4 is socketed on one of them pipe end, then another pipe end is also passed this seal ring 4, seal ring 4 is made to connect between ring body 5 two, and with two to dock the connecting sewing of pipeline corresponding, then the buckling groove 2 of arc pipe clamp body 1 internal surface is stuck on corresponding connection ring body 5, seal ring 4 is also corresponding is simultaneously placed in the annular groove 3 of arc pipe clamp body 1 internal surface, as shown in fig. 1, buckling groove 2 be connected ring body 5 clamping after, achieve the axially locating of arc pipe clamp body 1 on two docking pipelines 6, thus reach the object that pipeline is docked in connection two, simultaneously to dock the butt joint of pipeline 6 corresponding for seal ring 4 and two, the internal pressure of bearing pipeline is tightly attached on pipeline and forms sealing, another two pipe clamps are also installed in a manner mentioned above, just three pipe clamps share and have above-mentionedly overlapped the seal ring 4 connected, again adjacent is coupled together by clamping bolt 7 between pipe clamp between two after three pipe clamps install respectively, thus finally complete the connection of two pipelines, whole operating process is simple, be easy to operation, and join strength is high after connecting, comparing other mounting type has easy for installation, fast, sealing is reliable, antidetonation, the advantages such as resisted shrinkage expansion.

This pipe clamp structure is simple, be easy to dismounting, this pipe clamp structure produces certain drift angle and displacement after allowing pipeline to connect, and adopts this pipe clamp simultaneously and is connected ring body and is connected, effectively can prevent from overpressure from increasing uphold and pipeline be separated and leak, can guarantee that sealability reaches optimum efficiency.

Specific construction is simple, and can shorten for 1/3rd durations, sealing reliability is high, convenience easy to maintenance, and the mode using twice buckling groove to connect, improves use working pressure, solves the industry such as colliery, chemical industry pipeline and connects a difficult problem.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
