Abstract

The utility model discloses a pipeline fast-repair thread casing joint. Two sealing rings and a pair of conical claws are respectively sleeved on an orifice of a pipeline connected and are disposed in a cone hole of a locking sleeve. The conicity of the external conical surface of the claws matches with that of the cone hole of the locking sleeve. An inner hole of the claws matches with the external diameter of the pipeline connected. A sealing gasket is arranged at the part where orifices of two pipelines connected are in butt joint and is clamped by the pair of claws. A clamping element is installed on the locking sleeve, which is of a cylindrical shape and is provided with threads at the outer wall. The clamping element, a thread sleeve with a cylindrical structure, is provided at the inner wall with threads which match with the threads on the outer wall of the locking sleeve. The casing joint is reasonable in structure, good in sealing property, high in joint strength, simple in manufacture and rapid and convenient in installation and maintenance.

Description

Pipeline quick service screwed connection
Technical field
The utility model relates to pipe joint, especially a kind of pipeline quick service screwed connection that is used for the pipeline connection.
Background technique
Sphere of life piping facility construction development industry, agricultural and people is very fast, and the demand of tubing, pipe fitting is increasing.The quick repairing of pipe-line system has been urgent problem, and there is following deficiency in the also more and more common welding of the Placement of pipeline and link: 1, be subjected to the restriction of material easily, the tubing welding procedure that has is bad, is not suitable for welding processing; 2, welding is easy to generate bigger hot melt distortion and stress, causes pipeline to produce damage even slight crack; 3, sealability is low, and anti-leakage is poor; 4, need special welding equipment, be unfavorable for site operation.Be threaded and have following deficiency: 1, machining screw difficulty, particularly all the more so to thin wall metal pipeline, plastic tube and composite metal-plastic pipe etc.; 2, after the machining screw such as thin wall metal pipeline, plastic tube and composite metal-plastic pipe, intensity obviously reduces; 3, sealing effect is poor, anti-leakage is poor.Flange connects the shortcoming that exists: 1, need set up flange plate at pipe end, consumptive material is many, installation, maintenance is very uneconomical; 2, owing to a little less than the ability that thin wall metal pipeline, plastic tube and composite metal-plastic pipe etc. meet with stresses, can not guarantee sealing effect, the flange connection generally is difficult to be applicable to being connected of thin wall metal pipeline, plastic tube and composite metal-plastic pipe etc.; 3, flange plate end face seal life-span weak point easily leaks.
There is complex structure in existing pipe joint, and sealing effect is poor, especially uses inconvenient, the inefficient shortcoming of installation are installed, and has prolonged the repairing time, brings inconvenience for production, life.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, adapt to the needs that connect different tubing, provide a kind of rational in infrastructure, good seal performance, join strength height, make simple, installation and maintenance are efficient and convenient, need not special device can construct the pipeline quick service screwed connection that efficiency of construction is high at the scene.The utility model can be realized by following technical solution: pipeline quick service screwed connection, comprise claw, lock sleeve, clamping element, sealing gasket, seal ring, the claw of described two seal rings and a pair of taper is set on the mouth of pipe of connected pipe, and be arranged in the taper hole of lock sleeve, the tapering of the tapering of described claw male cone (strobilus masculinus) and lock sleeve taper hole is complementary, the endoporus of described claw and connected tube outer diameter are complementary, described sealing gasket is arranged on the mouth of pipe joint of connected two tubes and is clamped by a pair of claw, described clamping element is installed on the lock sleeve, the external form of described lock sleeve is a cylinder type, and its outer wall is provided with screw thread; Described clamping element is the thread bush of cylindrical structure, and its inwall is provided with screw thread, and is complementary with screw thread on the outer wall of lock sleeve.
Hand of spiral on the described a pair of lock sleeve outer wall is opposite.
The male cone (strobilus masculinus) of the claw of described a pair of taper is provided with annular groove, and described lock sleeve inner conical surface is provided with the projection that is complementary with it.
The utility model is suitable as metal tube, plastic tube, composite metal-plastic pipe etc., especially the seal connector of PPR pipe or PE pipe.
Superiority of the present utility model is: 1, the locking Placement of cone locking cover, and simple and compact for structure, application operating is easy, and the efficiency of construction height especially is fit to being tightly connected of tubule footpath pipe.2, the male cone (strobilus masculinus) of taper claw is provided with annular groove, and described lock sleeve inner conical surface is provided with the projection that is complementary with it, has improved the join strength of connected pipe.3, adopt nose end face seal pad and pipe axial sealing ring double-layer sealing structure, good seal performance.4, shortened the repairing time, given and produce, live and provide convenience.
