Abstract
The utility model relates to an interior carminative joint of withholding, including connecting the inner tube, the joint outer tube has been cup jointed to the one end periphery that connects the inner tube, connects inside and outside guan shangjun and is equipped with the cusp draw -in groove, connecting the inner tube and connecting to form between the outer tube and seal the cavity, the valve body is installed to the tip of cavity, and the cavity passes through with the body that connects the inner tube is inside the valve body communicates with each other. The utility model discloses solved effectively that the inside gas of multilayer non -metallic pipe gathers and the body inefficacy problem that leads to, accessible time to intraductal emission when the gas pressure who connects the storage of inside and outside pipe clamp layer reaches the setting value, be adapted to deep water, the unable outside carminative field in the ground non -metallic pipe line of burying. The utility model discloses simple structure, sealing performance is good, the bearing capacity is strong, is suitable for batch production, can satisfy the demand and develop the market demand of this work.
Description
Technical field
The utility model relates to a kind of buckle press joint, and especially a kind of buckle press joint with interior degassing function, belongs to pipeline construction technology field.
Background technology
Pipe joint is in the market of a great variety, but in the use procedure of deep water, the nonmetal pipe line such as buried, due to the body Problem of Failure that in pipe, outwards exhaust causes multilayer non-metallic pipe internal gas to gather and then occur.
Utility model content
The technical problems to be solved in the utility model is the defect for prior art, provide a kind of easy to operate, rational in infrastructure, good seal performance, bearing capacity strong, can effectively solve that multilayer non-metallic pipe internal gas gathers and the interior exhaust joint pipe of the body Problem of Failure that causes.
The utility model is technical solution problem by the following technical programs, and a kind of buckle press joint of interior exhaust comprises joint inner tube, and one end periphery of joint inner tube is socketed with joint outer tube, is equipped with dentation draw-in groove on joint inner and outer pipe; Between joint inner tube and joint outer tube, form sealed cavity, the end of cavity is provided with valve body, and cavity communicates by described valve body with the body inside of joint inner tube.
Further, the junction block of aforesaid interior exhaust, is provided with outside dentation draw-in groove on the madial wall of joint inner tube, be provided with inside dentation draw-in groove on the lateral wall of joint outer tube.
Further, the junction block of aforesaid interior exhaust, draw-in groove is stepped tooth.
Further, the junction block of aforesaid interior exhaust, the rear of valve body is installed with non-metallic pipe.
Further, the junction block of aforesaid interior exhaust, the sealed cavity between the end of non-metallic pipe and joint inner and outer pipe is connected.
Further, the junction block of aforesaid interior exhaust, the end of joint outer tube has inside flanging, and the top of described flanging and joint inner tube fit.
Further, the junction block of aforesaid interior exhaust, joint outer tube is fixedly connected with by welding or connector with joint inner tube.
The beneficial effects of the utility model are: the junction block of the interior exhaust that the utility model provides, effectively solve that multilayer non-metallic pipe internal gas gathers and the body Problem of Failure that causes, reach setting value at the gas pressure of joint inner and outer pipe interlayer storage and time can in pipe, discharge in time, be adapted in deep water, buried nonmetal pipe line the outwards field of exhaust. The utility model is simple in structure, good seal performance, bearing capacity are strong, is suitable for batch production, can satisfy the demand and carry out the market demand of this work.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described.

Detailed description of the invention
Embodiment
As shown in Figure 1 and Figure 2, a kind of junction block of interior exhaust, comprises joint outer tube 1, joint inner tube 3, valve body 2 and non-metallic pipe 4 to the structure of the present embodiment.
Wherein, the periphery of joint inner tube is socketed with joint outer tube, and the two is fixedly connected with by the mode of welding. And pass through special crimping equipment by joint outer tube undergauge, and make the end of joint outer tube there is inside flanging, the top of this flanging and joint inner tube fit. And on the madial wall of joint inner tube, be provided with outside dentation draw-in groove, on the lateral wall of joint outer tube, be provided with inside dentation draw-in groove. This dentation draw-in groove is stepped tooth, along being circumferentially uniformly distributed of joint inner and outer pipe.
The cavity that has formed a sealing between joint inner tube and joint outer tube, is provided with valve body in the end of this cavity, discharges in pipe in order to the gas that non-metallic pipe interlayer is gathered.
The using method of the present embodiment is: first adopt the mode of welding that joint inner and outer pipe is welded together; In the time assembling with non-metallic pipe, first non-metallic pipe put into inner and outer pipe gap, then adopted special crimping equipment by outer tube undergauge, so that inner and outer pipe is fixed non-metallic pipe; And, between joint inner and outer pipe and non-metallic pipe, should be not less than 150MPa(P1) and keep sealing under pressure, the interlayer between joint inner and outer pipe can be stored the gas overflowing from non-metallic pipe intermediate layer. A Special valve body is installed in the interlayer between joint inner and outer pipe, as shown in Figure 2, Special valve body need bear on the one hand and be not less than 150MPa(P1) overpressure, on the other hand after overpressure removal, can be by the gas of joint interlayer place storage being no more than 0.05MPa(P2) in pipe, discharge when pressure.
In addition to the implementation, the utility model can also have other embodiments. All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
