Abstract
The invention discloses a pipeline quick service sleeve joint, wherein two sealing rings and one pair of tapered claws are respectively sleeved on pipe mouths of connected pipes and arranged in tapered holes of a locking sleeve, the taper of the outer tapered surfaces of the claws is matched with the taper of the tapered holes of the locking sleeve, inner holes of the claws are matched with outer diameters of the connected pipes, a sealing cushion is arranged at a place where pipe mouths of the two connected pipes are abutted, and is clamped by the pair of claws, and a clamping member is arranged on the locking sleeve. The locking sleeve is provided with a flange, and the flange is provided with bolt holes. The sleeve joint has the advantages of reasonable structure, good sealing property, high connection strength, simpleness in manufacture, and convenience and rapidness in installation and maintenance.
Description
Technical field
The present invention relates to pipe joint, especially a kind of pipeline quick service sleeve joint 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 the also more and more common welding of the Placement of pipeline and link exist following not enough: 1, receive the restriction of material easily, the tubing welding procedure property 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.Being threaded, it is following not enough to exist: 1, machining screw difficulty, and 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, the easy leakage.
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 objective of the invention is to overcome the deficiency of existing technology; Adapt to the needs that connect different tubing; Provide a kind of rational in infrastructure; Good seal performance, join strength be high, it is simple to make, installation and maintenance are efficient and convenient, need not special device can construct the pipeline quick service sleeve joint that efficiency of construction is high at the scene.
The present invention can realize through following technological scheme: pipeline quick service sleeve joint; 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 is arranged in the taper hole of lock sleeve, and 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, and described clamping element is installed on the lock sleeve, and described lock sleeve is provided with flange plate; On the described flange plate bolt hole is arranged, described clamping element is a bolt clip stressed joint structure.
Have three groups of bolts hole on the described flange plate at least, a pair of lock sleeve clamping is linked together with at least three group bolt and nuts.
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 present invention 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 invention is: 1, the locking Placement of cone locking cover, and simple and compact for structure, application operating is easy, and efficiency of construction is high, especially is fit to being tightly connected of big caliber 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.
