Abstract
The invention relates to a joint for a helix reinforced pipe. The joint is provided with a neutron and a body, wherein the body is in abutting joint with the neutron; the neutron and the body are connected through a screw cap which is sleeved outside the body and the neutron; a radial slot is arranged on a matching surface of the outer wall of the neutron on the outermost minor caliber of the screw cap; an O-shaped sealing ring of the screw cap hermetically matched with the outer wall of the neutron is arranged in the radial slot; in the screw cap, an annular metal gasket is positioned between the front end surface of the neutron and the front end surface of an outside thread of the body; an annular groove is arranged on one side surface of the annular metal gasket; an O-shaped sealing ring is arranged in the annular groove; and an annular rubber gasket is arranged between the annular metal gasket and the front end surface of the outside thread of the body. The joint for the helix reinforced pipe is hermetic and labor-saving, and can make the pipe arbitrarily rotate so as to achieve double effects. Development of the product greatly reduces labor intensity of an operator, and also improves working efficiency.
Description
Technical field
The present invention relates to a kind of pipe joint, especially relate to a kind of improvement of rotary spiral reinforced pipe joint structure.
Background technique
The thread type spiral strengthens the suction Pipe joint, is to be connected sealing with neutron by nut by body, adopts internal thread between nut and the body and screws into the formula composite structure.In order to prevent to leak, the rubber sheet gasket sealing is adopted in the nut the inside.When internal and external threads screwed in, the outside thread front end on the body was just run into rubber sheet gasket, compresses rubber sheet gasket after running into, with face contact seal.In order to reach the purpose of sealing, must tighten joint, be screwed into last place, must extremely exert oneself.Therefore, prior art need be installed long handle in order to tighten joint on nut or body, perhaps need special tightening tool.By tightening later joint with this way, the water pipe that is connected on the joint can not produce revolution, so will operate very heavy suction sleeve the time, operation bothers very much.
Summary of the invention
To be that exploitation is a kind of tighten laborsavingly main purpose of the present invention, seals thread type connector for helically reinforced pipe easily.
Another object of the present invention is that water pipe can any rotating thread type connector for helically reinforced pipe after a kind of connection sealing of exploitation.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of connector for helically reinforced pipe, has neutron, the body that docks with neutron, neutron is connected with the nut of neutron outside by being socketed in body with body, described nut and neutron connecting end adopt along L shaped socket join structure, and nut and body connecting end adopt the internal and external screw thread linkage structure; On nut outermost end small-bore, have a radial groove with neutron outer wall fitting surface, in radial groove, be provided with a nut ○Xing Mifengquan that is sealed and matched with the neutron outer wall, make it play the seal action of nut and neutron; In the nut, between neutron front-end face and two end faces of this extracorporeal thread front-end face, be provided with the endless metal pad that adopts the aluminum or aluminum alloy gold to make, the internal diameter of endless metal pad is consistent with the neutron internal diameter, and external diameter matches with the nut internal diameter at corresponding position; On a side of endless metal pad, promptly an end face that cooperates with the neutron front end has a circular groove, and the pad ○Xing Mifengquan that protrudes in the plane is housed in the described circular groove; Be provided with a ring-shaped rubber pad between endless metal pad and this extracorporeal thread front-end face, the internal diameter of ring-shaped rubber pad is consistent with the neutron internal diameter, and external diameter matches with the nut internal diameter at corresponding position.
Therefore, the beneficial effect of the invention is: owing in the nut the inside metallic shim has been installed, the pad ○Xing Mifengquan has been installed between the surface of contact of metallic shim and neutron again.Like this, when pipe seal, be the ○Xing Mifengquan on the pad and the end face contact seal of neutron, pad and neutron end face are with line contact sealing, friction factor significantly reduces than the face contact of prior art.Therefore,, just can tighten sealing very doughtily, and after sealing, neutron can move commentaries on classics arbitrarily, drive the pipe revolution, play the laborsaving pipe that can make again of sealing and turn round arbitrarily, reach double effects as long as exert oneself slightly.Helically reinforced pipe is the conformal pipe, and bore is big and long, and because pipe can not turn round, it is very arduous to operate.This Products Development has alleviated operating personnel's labor intensity significantly, has also improved operating efficiency.

Accompanying drawing 2 is A-A sectional drawings of Fig. 1;
Accompanying drawing 3 is nut enlarged views of Fig. 2;
Accompanying drawing 4 is endless metal pad enlarged views of Fig. 2.
Embodiment
Below by embodiment also in conjunction with the accompanying drawings, technological scheme of the present invention is further described in detail.
Embodiment:
Pipe joint as shown in Figure 1 and Figure 2, has neutron 5, the neutron internal diameter is 69mm, the body 1 that docks with neutron, the body internal diameter is 69mm, neutron is connected with the nut 4 of neutron outside by being socketed in body with body, and nut 4 adopts along L shaped socket join structure with neutron 5 connecting ends, and nut 4 adopts internal and external screw thread 8 linkage structures with body 1 connecting end; On nut 4 outermost end small-bore, have a radial groove 41 (seeing shown in Figure 3) with neutron outer wall fitting surface, in radial groove, be provided with a nut ○Xing Mifengquan 6 that is sealed and matched with the neutron outer wall, make it play the seal action of nut and neutron; In the nut 4, between neutron front-end face and two end faces of this extracorporeal thread front-end face, be provided with the endless metal pad 3 that adopts aluminium to make, the internal diameter of endless metal pad is 69mm, and is consistent with the neutron internal diameter, and external diameter is 87.9mm; On a side of endless metal pad, promptly an end face that cooperates with the neutron front end has a circular groove 31 (seeing shown in Figure 4), annular groove width 2.1mm, and dark 1.5mm is equipped with the pad ○Xing Mifengquan 7 that protrudes in the plane in the groove; Be provided with a ring-shaped rubber pad 2 between endless metal pad 3 and body 1 outside thread front-end face, the internal diameter of ring-shaped rubber pad is consistent with neutron 5 internal diameters, and external diameter matches with the nut internal diameter at corresponding position.
The present invention with nut with neutron and body connection procedure in, adopt triple seal, the one, adopt nut ○Xing Mifengquan 6 and neutron outer wall fitted seal on the nut; The 2nd, the ring-shaped rubber pad 2 between neutron 5 and the body 1 reaches the plane sealing between neutron 5 and the body 1; Three are arranged on pad ○Xing Mifengquan 7 on the endless metal pad 3 and the line contact sealing between the neutron end face.Triple seal makes joint both have excellent sealing performance, makes operation easily again, and the neutron revolution freely under sealing state.
