Abstract
The utility model relates to a special pressure testing device for steel-plastic composite pipes, which is composed of a left blocking core and a right blocking core, wherein, the left blocking core is composed of a lining core, a sealing ring, a sleeve cylinder, a pressing block, and large screw nuts. The lining core is provided with the through hole of the shaft center; the left side of the lining core which is the external end of the lining core is provided with pipe threads which are used for being connected with a pressure test pump; the external column surface of the lining core is provided with screw threads which are matched with the large screw nuts; the right end of the liner core is a conical circular arc surface which is provided with the sealing ring; the lining core and the sealing ring are in the steel-plastic composite pipes for testing or in the left end holes of the pipe fittings, and the steel-plastic composite pipes on the end or the external column surfaces of the pipe fittings are tightly hooked with a pressing block which is provided with an annular groove. The end cover-type sleeve cylinder of the bearing is arranged on the lining core; the right end holds the sealing ring; the external end is embedded into the groove of the pressing block; the lining core on the external end of the sleeve cylinder is screwed with the large screw nuts, and the structures of the right blocking core and the left blocking core are the same. The special pressure testing device for a steel-plastic composite pipe has the advantages of firm clamp, simple structure, and convenient operation.
Description
(1), technical field
The utility model relates to a kind of special-purpose pressure testing device of steel-plastics composite pipe.
(2), background technology
Any pipe must be done various tests such as a series of pressure in process of production, and the used frock jig of whether accurate and test of test findings has confidential relation.All there is the test frock of oneself in the factory of present various pipes, and these test frocks can only be used for its different separately field.Because steel is moulded tube outer surface plasticity is arranged,, bring unnecessary economic loss to enterprise so use the structure for pressure test of steel pipe to come tested steel plastic composite and pipe fitting often owing to the mistake test does not tightly appear in folder.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of steel-plastics composite pipe special-purpose structure for pressure test, and not only clamping is firm for it, and simple in structure, easy to operate.
The technical scheme in the invention for solving the technical problem is: it comprises stifled core in a left side and right stifled core, wherein the stifled core in a left side comprises the lining core, O-ring seal, sleeve, briquetting and big nut, the lining core has axis through-hole, on the axis through-hole inwall pipe thread is arranged, be used for connecing test pump, on the external cylindrical surface of lining core the screw thread that cooperates with big nut is arranged, the right-hand member of lining core is the arc surface of taper, O-ring seal is arranged herein, above-mentioned lining core and O-ring seal are in the left end hole of tested steel-plastics composite pipe or pipe fitting, lock ring has briquetting on the external cylindrical surface of this end steel-plastics composite pipe or pipe fitting, briquetting has the groove of annular, the sleeve of bearing (ball) cover type is through on the lining core, and right-hand member withstands O-ring seal, and the outer end is embedded in the groove of briquetting, screw big nut on the lining core of sleeve outer end, screw big nut, O-ring seal can be held out against between lining core and steel-plastics composite pipe, make its secure seal; Right stifled core is identical with the stifled cored structure in a left side, and the axis hole of the lining core of the stifled core in a left side is equipped with air release outward.
In order to increase holding force of the present utility model, the hangnail that increases friction force is arranged on the briquetting inner hole wall that contacts with steel-plastics composite pipe.
Owing on the briquetting hangnail is arranged, increased the holding force of the utility model and tested steel-plastics composite pipe greatly, impermeability is good, and is simple in structure, easy to operate.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model cut-open view.
(5), embodiment
The utility model comprises stifled core in a left side and right stifled core, and wherein the stifled core in a left side comprises lining core 6, O-ring seal 5, sleeve 4, briquetting 3 and big nut 2, as shown in drawings.Lining core 6 has axis through-hole 1, and it is that the outer end has pipe thread that its left side is surveyed, and is used for connecing test pump.On the external cylindrical surface of lining core 6 screw thread that cooperates with big nut 2 is arranged, the right-hand member of lining core 6 is the arc surface of taper, and O-ring seal 5 is arranged herein.Above-mentioned lining core 6 and O-ring seal 5 are in the left end hole of tested steel-plastics composite pipe 7, lock ring has briquetting 3 on the external cylindrical surface of this end steel-plastics composite pipe 7, briquetting 3 has the groove of annular, in order to increase holding force of the present utility model, the hangnail that increases friction force is arranged on briquetting 3 inner hole walls that contact with steel-plastics composite pipe 7.The sleeve 4 of bearing (ball) cover type is through on the lining core 6, and right-hand member withstands O-ring seal 5, and the outer end is embedded in the groove of briquetting 3.Screw big nut 2 on the lining core 6 of sleeve 4 outer ends, screw big nut 2, O-ring seal 5 can be held out against between lining core 6 and steel-plastics composite pipe 7, make its secure seal.Right stifled core is identical with the stifled cored structure in a left side, and the axis hole of the lining core of the stifled core in a left side is equipped with air release 8 outward.
During use, with the two-port place of liner core plug at pipe, install briquetting, and briquetting is loaded with bolt, screw the big nut at two ends, sleeve compresses O-ring seal, relies on the tapering on the liner core that O-ring seal is outwards slided, thereby make O-ring seal being fitted on the tube inner wall tightly, reach the effect of sealing.On briquetting this moment the embracing on the outer wall of pipe tightly, briquetting and inside surface that pipe contacts many hangnails are arranged, these hangnails will embed in the outer plastic layer of pipe, thereby reach anti-slip purpose.Open air release, and with fills with water in the pipe, the bolt of air release is screwed, pressure rises to required test pressure and gets final product.
