Description

Groove pipeline clamp

Technical field

The utility model belongs to pipe fittings manufacturing technology field, is specifically related to a kind of groove pipeline clamp.

Background technique

The docking that pipeline clamp is applied to pipeline enclosure connects.There is following deficiency in existing pipeline clamp:

1, insufficient strength, easily there is opening when pressure increase in pipeline clamp, causes the joint of pipeline to produce water leakage phenomenon.

2, sealing is poor, and the joint of pipeline also can be caused to produce water leakage phenomenon.

Therefore, be necessary to carry out improvement and bring new ideas to the structure of existing pipeline clamp, overcome above-mentioned defect to make it.

Summary of the invention

For solving the above-mentioned technical problem that prior art exists, the utility model discloses a kind of groove pipeline clamp.

The utility model takes following technological scheme: groove pipeline clamp, comprises two clamp rings, bolt, nut, and clamp ring forms semicircular notch, and the notch of two clamp rings is spliced to form a circular channel relatively; The two ends of clamp ring body form lug respectively, and the corresponding lug of two clamp rings all reserves perforation; The both sides lug of two clamp rings is corresponding respectively, and is fixedly connected with through tightening nut after the perforation of corresponding lug by bolt; The both sides convex of clamp ring lug, and the transition position of lug and body is in skewed inwardly.

Preferably, along the circumferential direction form semicircular embedded groove in the middle part of the inwall of clamp ring, the embedded groove that after two clamp ring splicings, formation one is annular, the embedded groove of this annular is embedded in the seal ring suitable with its shape.

Preferably, along the circumferential direction annular groove is formed in the middle part of the inwall of seal ring.

Preferably, the dual-side of clamp ring body is along convex, and dual-side edge is skewed extension inwardly to notch direction.

The utility model groove pipeline clamp can be applied in the connection of groove pipeline, slot rolling pipeline, grooving pipeline, and goes for the groove pipeline clamp of various pressure range.

The utility model groove pipeline clamp has that intensity is high, the advantage of good airproof performance, thus makes the joint of pipeline enclosure not easily produce water leakage phenomenon.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the three-dimensional structure diagram of clamp ring.

Fig. 3 is the other direction three-dimensional structure diagram of clamp ring.

Embodiment

Below in conjunction with accompanying drawing, the utility model preferred embodiment is elaborated.

See Fig. 1-3, the present embodiment groove pipeline clamp, comprise two clamp rings 1, seal ring 2, bolt 3 and nut 4, clamp ring 1 forms semicircular notch 1-1, the clamp ring of a monolithic that the notch of two clamp rings 1 is spliced relatively, the clamp ring of this monolithic has a circular channel, and during for connecting two pipelines, the end of two pipelines to be stretched in this circular channel and clamped by two clamp rings 1.

Along the circumferential direction form semicircular embedded groove 1-2 in the middle part of (notch place) inwall of clamp ring 1, after two clamp rings 1 splice, form an annular embedded groove, the embedded groove of this annular is embedded in the seal ring 2 suitable with its shape.Annular groove 2-1 is along the circumferential direction formed in the middle part of the inwall of seal ring 2.When connection two pipelines, the butt joint of two pipelines is just positioned at the annular groove 2-1 of this seal ring.By seal ring, the butt joint sealing transition of two pipelines is coordinated.

The two ends (towards two side directions) of clamp ring 1 body form lug 1-3 respectively, and lug 1-3 reserves screw.The both sides lug 1-3 of two clamp rings 1 is corresponding respectively, and by bolt 3 through after corresponding screw, tightening nut 4 and being fixedly connected with.

The both sides of clamp ring lug 1-3 (i.e. pipeline stretch through direction) convex, and the transition position 1-4 of itself and body is in skewed inwardly.Adopt angular way to thicken lug, can effectively resist because internal pressure strengthens the two clamp ring junction openings produced.And adopt Platform Designing, make clip easily occur opening when pressure increase, cause the generation of water leakage phenomenon.

The both sides of clamp ring body (i.e. pipeline stretch through direction) edge 1-5 convex; it is skewed extension inwardly to notch 1-1; this place adopts angular way being subject to stress maximum position thickening shoulder key; effectively can resist transverse stress; reduce again the use of material simultaneously; avoid clip to rupture under large pressure or water hammer situation, effectively protect the safe operation of whole pipe-line system.Meanwhile, make again clip more attractive in appearance.According to flat mouth, need whole thickening, expense can be caused to expect and off size routine.

In pipeline connects, first seal ring is enclosed within the groove pipe end face of docking, the notch of two clamp rings is stuck in the both sides of pipeline, and encases seal ring, and last bolt is through preformed hole, and fastening nut simultaneously.When have in pipeline medium by time can produce certain pressure, pressure presses to the inner chamber of seal ring, and seal ring is owing to being close to clip clamp ring, therefore manifold pressure is larger, and the sealability of seal ring is better.

Above preferred embodiment of the present utility model is described in detail; for those of ordinary skill in the art; according to the thought that the utility model provides, embodiment will change, and these changes also should be considered as protection domain of the present utility model.
