Abstract
The utility model belongs to an improvement of a high and medium pressure pipe joint, particularly is a fast pipe joint, which comprises that: joints are respectively connected fixedly at the ends of two pipes; the ends of the joints are provided with flanges whose outer side surfaces are ring shape inclined surfaces; the inner sides of the end surfaces of the flanges are provided with ring shape concave platforms; the outer circumference wall is provided with two semicircle slips with tapers; the inner circumference wall is provided with a groove whose two side surfaces are inclined surfaces; the two inclined surfaces of the slip groove are respectively matched with the outer side surfaces of the flanges of the two pipe end joints; the outer cone surfaces of the two semicircle slips are matched with the cone holes of a lock sleeve; stop-backing lock edges are arranged on the large end surfaces of the cone holes of the lock sleeve; ring shape sealing pads are arranged in ring shape grooves with fit clearance formed by the ring shape concave platforms arranged in the inner sides of the flange end surfaces of the two pipe joints. The pipe can be connected fast by the utility model; the utility model has the advantages of convenient installation, low cost, fine sealing performance and high pressure bearing capacity.
Description
Technical field: the utility model belongs to the improvement of high pressure pipe coupling, particularly quick coupling.
Background technique: the joint of the steel pipeline of existing conveyance fluid, adopt the flange plate Placement mostly.But during the steel pipeline construction that connects with flange plate, enough operating spaces must be arranged, and the fastening force of the uniform bolt of flange plate must be consistent, otherwise easy to leak.
The Placement of existing nonmetal pipeline: forms such as have hot melt to connect, the CONCENTRIC REDUCER socket joint of pipeline connects, and rubber seal sealing or socket joint are gluing.These connections all have withstand voltage low (in the 1.6Mpa), dismounting difficulty, leakage rate height.
Summary of the invention: the purpose of this utility model is to provide a kind of quick coupling, and pipeline is connected fast, and easy for installation, cost is low, and good sealing effect, bears the pressure height.
The purpose of this utility model is achieved in that a kind of quick coupling, the affixed respectively joint in end that comprises two pipes, the termination of joint has flange, the outer side surface of flange is annular plane of inclination, the inboard of the end face of flange is provided with annular concave platform, outer circle wall has two semicircle slips of tapering, its inner peripheral wall is provided with the groove that bi-side are the plane of inclination, match with the outer side surface of two pipe end joint flanges respectively in two plane of inclination of slips groove, the outer conical surface of two semicircle slips matches with the cone shape hole of lock tube, retaining lock seaming is being set on the big end end face of lock tube cone shape hole, and the annular concave platform two pipe coupling flange end face inboards constitutes in the annular groove with matching gap Gask-O-Seal is installed.
When using the utility model, install Gask-O-Seal in the annular groove with two tubes end connector end face of flange inboard, two tubes end connector flange is closed up, with special tool two joints are connect tightly, two pipe end joint flanges of groove alignment of the circular slips of two halves are constituted the annular plane of inclination of boss, utilize two lateral incline of slips groove to compress the outer lateral incline of two joint flanges, force two joint flanges to produce axial motion, make matching gap between the two joint flange exterior edge faces reduce to come Gask-O-Seal in the hold-down ring connected in star.The resiliently deformable decrement of sealing gasket is compressed in the reasonable range, when reaching sealing effect, has also prolonged the working life of sealing gasket.Then the lock tube that has cone shape hole is sleeved on the cone of two semicircle slips compositions, carries out the examination jade of pipeline, behind the pressure testing ne-leakage, the available dedicated instrument is locked retaining, prevents to become flexible.Like this, whole pipeline just can come into operation.The utility model is easy for installation, and sealing effect is very good, and it is time saving and energy saving fast to connect, and has reduced mounting cost, has guaranteed withstand voltage, the resistant to elevated temperatures usability that tubing connects.Operating space required during installation is little, loads and unloads all very convenient.
Description of drawings: accompanying drawing is a structural representation of the present utility model.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing, a kind of quick coupling, quick coupling for the composite anti-corrosive pipe, the affixed respectively joint in end that comprises two pipes, the termination of steel joint 1 has flange 4, the outer side surface of flange 4 is annular plane of inclination, the inboard of flange 4 end faces is provided with annular concave platform 6, the outside of flange 4 end faces of two symmetries is being provided with the annular concave, convex platform 8 that cooperatively interacts respectively, the effect that the annular concave, convex platform 8 that cooperatively interacts plays is: when the flange butt joint of two pipes, and the centering location.Outer circle wall has two semicircle slips 3 of tapering, its inner peripheral wall is provided with the groove 7 that bi-side are the plane of inclination, match with the outer side surface of two pipe end joint flanges 4 respectively in two plane of inclination of slips groove 7, the outer conical surface of two semicircle slips 3 matches with the cone shape hole of lock tube 2, and the tapering of two semicircle slips 3 outer conical surface is 1: 15-1: 8.Retaining lock seaming 9 is being set on the big end end face of lock tube 2 cone shape holes, and retaining lock seaming 9 is the annulus limit of uniform opening.When pipeline butt joint installs the utility model, with special tool retaining 9 bendings of lockstitching a border are fastened on the end of slips 3, make lock tube 2 with slips 3 lockings.Annular concave platform 6 two pipe coupling flange 4 end face inboards constitutes in the annular groove with matching gap Gask-O-Seal 5 is installed, and Gask-O-Seal 5 is the fluorine rubber pad, and the thickness of Gask-O-Seal 5 is greater than the height of annular groove.The utility model can be used for nonmetal pipeline, as chlorinated polynvinyl chloride (CPVC)/composite glass steel pipe, also can be used for steel pipeline.When with chlorinated polynvinyl chloride (CPVC)/composite glass steel pipe, with the internal diameter of the utility model steel joint flange hangnail groove of having got on the bus, bond together by the pipe end of Bond, and carry out flange through the composite pipe lining pipe with the good tapering of the inner hole grinding with hangnail groove of joint flange.When being used for steel pipeline, the end that steel joint flange of the present utility model firmly is welded on steel pipeline gets final product.
