Abstract

The utility model relates to a connecting and fastening pipe sleeve. The connecting and fastening pipe sleeve comprises two arched pipe sleeve bodies (1), wherein the two arched pipe sleeve bodies (1) are placed oppositely, the two sides of one arched pipe sleeve body are fixed to the two sides of the other pipe sleeve body through bolts (2), and a passageway allowing a pipeline (3) to pass through is formed between the two arched pipe sleeve bodies (1); a cross groove is formed in the inner wall of each arched pipe sleeve body (1) to enable a cavity capable of surrounding the pipeline (3) to be formed inside after the two arched pipe sleeve bodies (1) are connected oppositely; an injection molding valve (5) is arranged on each arched pipe sleeve body (1), and the interior of each injection molding valve (5) is communicated with the cavity (4). The connecting and fastening pipe sleeve can be used for effectively sealing a leakage point of a pressure pipeline, so that the pressure pipeline can be used again, production cost is saved, the probability of potential safety hazards is reduced, and the problem that when the pressure pipeline leaks, the whole pipeline needs to be replaced or production needs to be stopped to carrying out welding is solved.

Description

A kind of connection fastening pipe sleeve

Technical field

The utility model belongs to the oil field equipment field, relates to a kind of connection fastening pipe sleeve, particularly a kind of connection fastening pipe sleeve for the pressure piping sealing.

Background technique

In field produces, the use of pressure piping is very general.From broadly understanding, pressure piping refers to all pipelines that bear interior pressure or external pressure, regardless of medium in its pipe." Safety Supervision on Special Equipment regulations " issued by the State Council clear, pressure piping and boiler, pressurized container, Hoisting Machinery are listed as the more special equipment of unsafe factor.The pressure born due to pressure piping is far longer than general pipeline, makes pressure piping easily leak, once and leak, the method that can adopt at present is exactly the pressure piping occur the leaked welding of changing or stop production.This kind of method wastes time and energy, and cost is very high, has very large potential safety hazard simultaneously.Therefore, need to for the problems referred to above invent a kind of can be by the device of the leakage point effective sealing of pressure piping.

Summary of the invention

The purpose of this utility model is to provide a kind of connection fastening pipe sleeve, solves in prior art that do not have can be by the device of the leakage point effective sealing of pressure piping, when pressure piping occurs to leak, and the problem of the welding of whole of pipeline can only being changed or stop production.

The utility model is achieved through the following technical solutions: a kind of connection fastening pipe sleeve, and this device comprises two arc pipe boxes, the staggered relatively and both sides of two arc pipe boxes are fixed with bolt, the passage that middle formation can be crossed for device for cleaning pipeline; Having translot on two arc pipe box inwalls makes two arc pipe boxes relatively can form the cavity that holds pipeline in the rear inside of connection; Two arc pipes put and are provided with the injection moulding valve, and injection moulding valve inside and cavity communicate.

Described injection moulding valve is at least two, and evenly arranges along two arc pipe box peripheries.

On the contact both sides face of described two arc pipe boxes, screw thread is arranged.

Adopt the good effect of technique scheme: the utility model can be sleeved on leakage point place, the pipeline outside, by to the pipeline outside high pressure, injecting sealing compound, reach the effect of closed conduit leakage point, make pressure piping to re-use, save production cost, and need not stop production, can guarantee normal operation and the environmental contamination reduction produced; Carry out installation and maintenance owing to having adopted the utility model not get angry, therefore reduced to greatest extent potential safety hazard, and can design the pipe box of different model according to the size of operating space, leakage point place and the actual demand of leak stopping, enlarge application area of the present utility model.

The accompanying drawing explanation

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

Fig. 2 is the longitudinal section of Fig. 1;

Fig. 3 is the plan view of Fig. 1.

In figure, 1 arc pipe box, 2 bolts, 3 pipelines, 4 cavitys, 5 injection moulding valves.

Embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but should not be construed as restriction of the present utility model:

Fig. 1 is structural representation of the present utility model, Fig. 2 is the longitudinal section of Fig. 1, Fig. 3 is the plan view of Fig. 1, shown in Fig. 1, Fig. 2, Fig. 3, a kind of connection fastening pipe sleeve, this device comprises that 1, two arc pipe box 1 of two arc pipe boxes is staggered relatively and both sides are fixing with bolt 2, the passage that middle formation can be passed through for pipeline 3.After connecting, two arc pipe boxes 1 pipeline tightly can be embraced.Have translot on two arc pipe box 1 inwalls and make two arc pipe boxes 1 relatively can form the cavity 4 that holds pipeline 3 in the rear inside of connection, cavity is for holding the sealing compound of shutoff leakage point.Two arc pipe boxes 1 are provided with injection moulding valve 5, and injection moulding valve 5 inside and cavity 4 communicate.The injection moulding valve connects injection gun outward, for sealing compound is injected.

Because sealing compound is solid colloid, uneven in order to prevent that sealing compound from injecting, cause partial high pressure, described injection moulding valve 5 is at least two, and a plurality of injection moulding valves 5 are evenly arranged along two arc pipe box 1 peripheries.

For enhanced leaktightness further, prevent from revealing, on the contact both sides face of described two arc pipe boxes 1, screw thread is arranged.

In production, when the somewhere of finding pressure piping occurs to reveal, two arc pipe boxes of the present utility model are staggered relatively in the pipeline outside, and the translot on arc pipe box inwall is corresponding with the position of pipe leakage point, as shown in Figure 2, then by the both sides bolton of two arc pipe boxes.After the injection moulding valve that injection gun is put with arc pipe is connected, directly inject sealing compound.After sealing compound enters the cavity that holds pipeline, the shutoff leakage point, because the pressure that injects sealing compound is far longer than the pressure of leaking medium, therefore leak and stopped by force, sealing compound self also can be maintained certain operating unit sealing load, and change elastomer into by plastomer at short notice, and form hard, a whippy new sealing layer, reach the purpose again be fastenedly connected.The utility model makes pressure piping to re-use, once solve, occur to leak must the whole problem of changing or stop production welding, has greatly saved the cost of production in oil field, has reduced potential safety hazard.
