Abstract
The utility model relates to a special composite pipe joint belonging to the field of pipe joints or pipe fittings, particularly pipe joints of composite pipes. The special composite pipe joint is composed of a joint body, a rubber ring, a sleeve ring, and a clamp nut. The joint body is provided with a contact body portion with a composite pipe inserted in. The inner surface of an end surface matched with the clamp nut on the joint body is provided with a tapered surface. The tapered surface is provided with an annular groove. The rubber ring is arranged in the annular groove. The utility model has the advantages of simple structure, easy manufacturing, convenient assembly and disassembly, multiple sealing performance, and high sealing reliability. The special composite pipe joint is suited to various pipe joints of special composite pipes.
Description
The utility model specific complex pipe joint belongs to the pipe joint in pipe joint or pipe fitting field, particularly composite pipe.
The pipe joint form of existing composite pipe has multiple, what generally adopt is to adopt on the fittings body to have the contact part of inserting composite pipe, the insertion portion of contact has many annular grooves on the outer surface, rubber ring is housed in the annular groove, the insertion portion of contact is inserted in the pipe, utilize tightening nut the collar to be fastened on the pipe of the insertion portion of contact on the fittings body, make rubber ring and pipe sealing in the annular groove, the processed complex of the pipe joint of this property formula, the dismounting inconvenience of pipe can be leaked between fittings body and the pipe.
The purpose of this utility model is to be to avoid the deficiencies in the prior art and to provide a kind of simple in structure, has the specific complex pipe joint of multi-sealed performance.
The utility model is according to the characteristics of specific complex pipe, in conjunction with prior art, a kind of pipe joint of triple seal is proposed, the purpose of this utility model reaches by following measure, it is by fittings body, rubber ring, the collar, tightening nut is formed, on fittings body, have the contact part of inserting composite pipe and the screw thread that matches with tightening nut, the end face internal surface that matches with tightening nut on fittings body has a conical surface, and an annular groove is arranged on conical surface, and rubber ring is placed in the annular groove, in the exterior edge face of the collar one conical surface is arranged, match with the end face conical surface on the fittings body, one conical surface is arranged, match with rubber ring in the annular groove on the conical surface on the fittings body at the interior edge face of the collar.When connecting the specific complex pipe, rubber ring, the collar and tightening nut are enclosed within on the composite pipe, the termination that the contact of the insertion composite pipe on the fittings body is partly inserted composite pipe, rubber ring is placed in the annular groove, the collar is held out against rubber ring, on the screw thread that tightening nut is screwed on the fittings body with tightening nut matches, utilize tightening nut the collar to be fastened on the insertion portion of contact on the fittings body, because the characteristics of specific complex pipe, the elasticity of plastics, between the contact of the insertion composite pipe on fittings body part and specific complex pipe, form first resealing, the annular groove place of placing at rubber ring forms second resealing, form triple seal between the internal surface of the collar and the specific complex pipe, improved the reliability of pipe seal.
The utility model goes for the adapter piece of various pipes, as three-way pipe etc., according to the Placement of pipe, can be to connect pipe, or another pipe joint.
The utility model is simple in structure, easy processing, and easy accessibility has multi-sealed performance, and the reliability height of sealing is suitable for the various pipe joints of specific complex pipe.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in drawings, the utility model is by fittings body 1, rubber ring 6, the collar 8, tightening nut 10 is formed, end at fittings body 1 has contact 5 parts of inserting composite pipe, on fittings body, have the screw thread 2 that matches with tightening nut, end at fittings body has connecting thread, and the end face internal surface that matches with tightening nut on fittings body has a conical surface 4, and an annular groove 3 is arranged on conical surface, one conical surface 7 is arranged in the exterior edge face of the collar, match with the end face conical surface on the fittings body, one conical surface 11 is arranged, match with rubber ring in the annular groove on the conical surface on the fittings body at the interior edge face of the collar.Rubber ring 6 is placed in the annular groove 3, there is a conical surface another exterior edge face at the collar, matches with screw thread chamfering in the tightening nut, because the effect of conical surface, the collar is slided between fittings body 1 and tightening nut 10, produce axially and radial compression; Play the effect of sealing, place the effect that rubber ring plays sealing in the annular groove on conical surface.
