Abstract

The utility model relates to an adaptor for a pipe, which belongs to the field of pipe joints, and solves the technical problem that the adaptor for a pipe can be connected with a pipe joint when screws are not processed. The adaptor for a pipe is characterized in that an outer circle installed on the end of the pipe joint is a rubber sealing ring of which both ends are in a conical shape; one end of the rubber sealing ring is sheathed in a bearing body which is provided with corresponding conical holes, and one end of a joint nut with corresponding conical holes issheathed on the other end; the other end of the joint nut is connected with the outer screw of the bearing body; when the joint nut is screwed tightly, the pipe joint is wrapped tightly by extruding force and the elasticity of the rubber sealing ring. The utility model has the advantages of labor saving, quick installation, etc. The adaptor for a pipe is used in all mine enterprises and engineering which need to convey low pressure media.

Description

The new-type joint of pipe fitting

The utility model relates to the new-type joint of a kind of pipe fitting, belongs to the pipe joint field.Thread connecting mode is generally adopted in the connection of pipes and tubes at present, be threaded will be on pipe fitting machining screw, time-consuming, take a lot of work, cost is higher, also will add paint, the sealing of money wet goods with the rope made of hemp or asbestos rope during installation, installation rate slowly, inconvenient maintenance.

The purpose of this utility model provides not machining screw of a kind of connecting end at pipe fitting, the new-type joint of a kind of pipe fitting that install rapidly, saves labor.

The purpose of this utility model is that following technical measures realize:

The new-type joint of pipe fitting is made up of Female connector fittings, rubber seal, pressure-bearing body, and the end face endoporus of pressure-bearing body is that big, inner little taper hole, its oblique angle, outer end is 6 °-10 °, and outer garden end face has screw thread.The pressure-bearing body is elbow unions, reducing socket, triangle pipe joint, union cross.The little two taper in two broad in the middle, outer garden of rubber seal, its oblique angle are that an end of endoporus has the end face back-up ring within 6 °-10 °; One of Female connector fittings endoporus has screw thread, the outer end, other end is little, the inner end is big taper hole, and its oblique angle is 6 °-10 °.Machining screw not on the pipe fitting has been installed rubber seal at the one end, and rubber seal connecting leg spare has been installed in together in the end taper hole of pressure-bearing body, and the other end of Female connector fittings is connected with the outside thread of pressure-bearing body; The end face of pipe fitting withstands on the step of pressure-bearing body endoporus by the back-up ring of seal ring, and having reached pipe fitting does not have the purpose that is threaded.

Excellent beneficial effect of the present utility model is: not be used in machining screw on the pipe fitting, thereby reduced the operation of machining screw, reduced cost owing to only Female connector fittings is rotated when mounted, therefore economize merit, laborsaving, increase work efficiency.

Description of drawings: Fig. 1 is that structural representation, Fig. 2 of the new-type joint of pipe fitting is that elbow unions structural representation, Fig. 3 are the reducing socket structural representation, and Fig. 4 is the tee union structural representation, and Fig. 5 is the union cross structural representation.

Below in conjunction with description of drawings embodiment of the present utility model:

The new-type joint of pipe fitting comprises that Female connector fittings 1, rubber seal 2, pressure-bearing body 3, pipe fitting are steel pipe or plastic tube, in its connecting end machining screw not, before installing with emery cloth sand fleece suit has been installed behind end face rubber seal 2, and its connecting leg spare is assemblied in together in the pressure-bearing body of corresponding taper hole, the end face of pipe fitting withstands on the step of pressure-bearing body taper hole bottom by the ring washer of rubber seal end face, an another awl end of rubber seal 2 and an end taper hole socket of Female connector fittings, the other end of Female connector fittings is connected with the outside thread of pressure-bearing body 3.When Female connector fittings is tightened in the pressure-bearing body, its inclined-plane produces extruding force to the rubber seal with respective ramp, thereby further resiliently deformable takes place and packs tightly pipe fitting in rubber seal, in order to reach Cui and maximum sealing and extruding force, the oblique angle on Female connector fittings, pressure-bearing body and the rubber seal is all elected 6 °-10 ° as.Thereby can bear the axial reaction force in the joint.The new-type joint of this pipe fitting is widely used in all engineerings, unit and the department that the blow-off line system of water supply pipe, industrial enterprise, large-scale water changing engineering etc. need to carry the low-pressure medium.

Claims

1, the new-type joint of pipe fitting, it comprises Female connector fittings (1), rubber seal (2), pressure-bearing body (3), it is characterized in that being equipped with in the end face taper hole of pressure-bearing body (3) an awl end of seal ring (2), one end taper hole socket of the other end of seal ring (2) and Female connector fittings (1), the other end of Female connector fittings (1) is connected with the outside thread of pressure-bearing body (3), and the end face of the pipe fitting of installing in the endoporus of seal ring (2) (4) withstands on the step of pressure-bearing body (3) endoporus by the back-up ring of seal ring.

2, the new-type joint of pipe fitting according to claim 1, the end face endoporus that it is characterized in that pressure-bearing body (3) is that big, inner little taper hole, its oblique angle, outer end is within 6 °-10 °, outer garden end face has screw thread, and pressure-bearing body (3) is reducing socket, three-way union, the union cross in elbow unions, different true footpaths.
