Abstract
The utility model relates to a high-pressure refractory quick joint pipe piece, which is composed of a connecting body 1 with a through hole, a screw nut 4 connected with the connecting body 1, and a frame-shaped sleeve 2 and an annular tight sleeve 3 which are arranged between the connecting body 1 and the screw nut 4. The end head of the connecting body 1 is provided with a screw. The high-pressure refractory quick joint pipe piece is widely used for connecting water, steam and oil pipelines, and is refractory and resists high pressure. The utility model has the advantages of simple and quick operation, labor saving, and time saving; the high-pressure refractory quick joint pipe piece can increase the service life of pipes.
Description
The utility model belongs to pipe joint, the pipe fitting that particularly quick type connects.
Existing pipe joint all is by screw thread pipe to be linked up as pipe collar, threeway, elbow etc., must be to the pipe hitch during operation, and then pipe is screwed in the above-mentioned pipe fitting, like this, not only time-consuming, and the cover buckle of pipe corrodes easily, influences the tubing life-span.
The purpose of this utility model provides a kind of quickly jointed tubular workpieces easy, saving of work and time that assembles.
The utility model is wherein to have through hole, the screwed junctor 1 in termination to be conical nut 4 with its internal surface that links to each other with junctor 1 by screw thread by one, and places the FangXing Tao 2 between nut 4 and the junctor 1 to form.
Junctor 1 can be made into pipe collar, threeway or bending head type, also can be made into diameter reducing type, can also be made of one with valve, flange.Cover 2 is made of metal, and its material is decided on the material hardness and the surface state of coupled pipeline, guarantee under the state of fastening nut 4, and cover 2 has enough distortion, with the locking pipeline, and reaches sealing effect.
Pipeline is being had under the situation of specific (special) requirements, be oil, during vapour, or when under high-temperature high-pressure state, using, annular also can be installed between FangXing Tao 2 and junctor 1 tightly overlap 3 as the pipeline medium.The tight cover 3 of annular is made of metal.
The utility model has the advantages that pipe without hitch, directly insert in the junctor 1 of the present invention that fastening nut 4 then, will overlap 2 and tight cover 3 be enclosed within outer tube surface tightly, reach the purpose of sealed attachment.Simple to operation quick, and the working life that can improve pipe.This quickly jointed tubular workpieces is applicable to various water, vapour, the oil pipe line installation of φ 4-φ 20mm or 1/2-3 inch, high temperature high voltage resistant.
