Abstract

The utility model discloses an urgent repair clamp for water pipes. The utility model comprises iron shells which are embraced into a pipe shape by half, a sealing rubber cushion which is arranged on the iron shells and is sealed along the connecting seam, and bolts which cause the two half iron shells to be fastened and embraced. The sealing rubber cushion is integrally formed with a sealing ring along the end openings of the iron shells. The sealing ring is inlaid in ring grooves of the end openings of the iron shells. The inner ring end surface of the sealing ring forms a double arc surface ring shape. Through the design, the utility model forms the line contact type sealing with the required pipelines, and the sealing achieves more than two layers. The utility model has the advantages of good sealing effect, no water leakage, no gas leakage, convenient and rapid construction and repair, etc.

Description

Water pipe repairing folder

The utility model relates to the technical field of water pipe line maintenance unit, particularly a kind of pipe clamp of rushing to repair usefulness.

The pipe clamp of water pipe repairing usefulness, its effect is the maintenance of carrying out pipeline burst, seepage etc. under the situation of cutting off the water of need not operating a switch, when certain section explosion appears on the water pipe line, when leaking, the pipe clamp of two halves is set on the pipeline of explosion, clamping bolt closes pipe clamp tightly, the environmental sealing pipeline, thus avoid cutting off the water, excavate road, more renew the trouble of pipe etc.But what its port sealing circle of traditional pipe clamp adopted is zigzag three fan RunddichtringOs, when the pipe clamp obvolvent clamps with quilt repairing pipeline, the sealing circle contacts with the surface formation face of being rushed to repair pipeline, as long as pipeline Surface deformation degree is big slightly, perhaps the seal ring position of putting coincide inadequately, just be easy to cause phenomenons such as leaking appears in sealing repairing place, gas leakage, influence repairing effect.

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and the water pipe repairing folder of a kind of convenient and quick construction, good sealing effect is provided.

The purpose of this utility model is achieved by the following technical solution: water pipe repairing folder, include the iron-clad that half-and-half to fill the span of a man's arms into tubulose, be loaded on the iron-clad and along the seal rubber pad of joint close sealing, with the fastening bolt of filling the span of a man's arms of two halves iron-clad, it is characterized in that: iron-clad port, seal rubber pad upper edge is one-body molded seal ring, seal ring is embedded in the annular groove of iron-clad port, and the interior ring end face of seal ring is two cambered surface annulars.Further, the cross section of the interior ring of seal ring end face is two arcs of midfeather.Certainly, further, the ring end face can be three or above cambered surface annular in the seal ring.

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

Fig. 2 is the A-A sectional drawing of Fig. 1;

Fig. 3 is that schematic representation is looked on the left side that Fig. 1 removes bolt;

Fig. 4 is the enlarged diagram of the part of Fig. 3 seal ring.

Below in conjunction with drawings and Examples structure of the present utility model and advantage are described further.

Referring to Fig. 1-Fig. 4, present embodiment is mainly by a pair of spheroidal graphite cast iron shell 1 of filling the span of a man's arms into tubulose, be put in the seal rubber pad 2 on iron-clad 1 joint close, with two iron-clads 1 fill the span of a man's arms the back fastening, the sealing bolt 3, and constitute with the seal ring 4 of seal rubber pad 2 disjunctor moulding, seal ring 4 can be embedded in the annular groove 11 of iron-clad 1 port, and two cambered surfaces 41 of spacing are arranged in the middle of the working seal face of seal ring 4 is, the interior ring end face that is seal ring 4 is two cambered surface annulars, but has between two cambered surfaces at interval.Like this, when pipeline that repairing folder clamp leaks, the working seal face of seal ring 4 with formed line by the surface of repairing pipeline and contact, and be the contact of two-wire line, when bolt 3 tightens up, iron-clad 1 and quilt are rushed to repair between the pipeline are formed double-layer seal.Certainly, here only enumerated a kind of preferred implementation, in fact in the working seal face of seal ring 4-promptly the ring end face can be three gapless continuous cambered surface annulars or more than three in the middle of spaced cambered surface, decide on concrete applicable cases, repeat no more here.

In sum, the utlity model has obvious advantage:

1, sealing ring adopts the working face of arc surfaced, makes it and rushed to repair pipeline formation line to connect Touch, better with the equal pressure seal performance;

2, two or more arc surfaced reaches two-layer or above sealing, the sealing reliability height;

3, the construction repairing is convenient and swift, non-leakage, water-tight.

Claims

1, water pipe repairing folder, include the iron-clad that half-and-half to fill the span of a man's arms into tubulose, be loaded on the iron-clad and along the seal rubber pad of joint close sealing, with the fastening bolt of filling the span of a man's arms of two halves iron-clad, it is characterized in that: iron-clad port, seal rubber pad upper edge is one-body molded seal ring, seal ring is embedded in the annular groove of iron-clad port, and the interior ring end face of seal ring is two cambered surface annulars.

2, repairing folder according to claim 1 is characterized in that the cross section of ring end face in the seal ring is two arcs of midfeather.

3, repairing folder according to claim 1 and 2 is characterized in that the ring end face can be three or above cambered surface annular in the seal ring.
