Abstract
The utility model relates to a pipe fitting pressure test connecting device, in particular to a steel tube connecting device. The steel tube connecting device comprises a clamp connector, a positioning clamping sleeve and a seal ring. A boss is integrally fixed at the left end of the clamp connector and the inner diameter of the boss is smaller than that of the clamp connector. Threads are arranged on the left portion of the boss, and threads are arranged on the outer side of the right portion of the clamp connector. The inner side of the right end of the clamp connector is in the shape of a frustum which is narrow in the left and wide in the right. The left portion of the positioning clamping sleeve and the right portion of the clamp connector are fixedly connected together through the threads. A seal ring is arranged on the inner side of the right end of the clamp connector through the positioning clamping sleeve in an abutting-against mode. The steel tube connecting device is reasonable and compact in structure and convenient to use. Due to the fact that a rigid round tube and seal packing are pressed tightly through fastening threads, the seal effect is achieved, and mutual connection and seal between rigid round tubes are achieved. After pressure test is finished, the steel tube connecting device is convenient to disassemble. Therefore, working efficiency is improved, and meanwhile production cost is reduced.
Description
Technical field
The utility model relates to pipe fitting pressure testing connection set, is a kind of steel pipe connection set.
Background technique
To steel tube pressure-measuring the time, adopt the method for welding that many steel pipes are together in series at present usually and carry out pressure testing, after pressure testing finishes weld seam is cut the back rigidity pipe redundance is cut with flame or mechanical means.This method not only causes raw-material waste, and the auxilliary material and the manpower that drop into are also bigger, inefficiency.
Summary of the invention
The utility model provides a kind of steel pipe connection set, has overcome the deficiency of above-mentioned prior art, and it can effectively solve the existing ineffective problem of steel tube pressure-measuring connection set.
The technical solution of the utility model is achieved like this: a kind of steel pipe connection set comprises jig joint, positioning sleeve and seal ring; The left end one of jig joint fixedly has internal diameter less than the boss of jig joint internal diameter, left part at boss has screw thread, there is screw thread in the right part outside at the jig joint, the right-hand member inboard of jig joint is the wide taper type in the left narrow right side, the right part of the left part of positioning sleeve and jig joint is fixed together by screw thread, in the right-hand member inboard of jig joint the seal ring that holds out against by positioning sleeve is arranged.
Above-mentioned seal ring is and the inboard corresponding taper type of the right-hand member of jig joint.
The left end one of above-mentioned positioning sleeve fixedly has the annular boss that can withstand seal ring.
Be set with seal ring on the positioning sleeve in the above-mentioned annular boss outside.
The left part of above-mentioned boss has internal thread or outside thread.
Above-mentioned seal ring is graphite packing seal ring.
The utility model reasonable and compact in structure, easy to use, compress the rigidity pipe and sealed packing reaches sealing effect by binding thread, realize being connected to each other and sealing between the rigidity pipe, be convenient to dismounting after pressure testing finishes, therefore not only having improved working efficiency has also reduced cost of production.
Description of drawings
Fig. 1 is that master of the present utility model looks and cuts open structural representation.
Coding among the figure is respectively: 1 is the jig joint, and 2 is positioning sleeve, and 3 is seal ring, and 4 is boss, and 5 is annular boss, and 6 is seal ring, and 7 is steel pipe.
Embodiment
As shown in Figure 1, this steel pipe connection set comprises jig joint 1, positioning sleeve 2 and seal ring 3; The left end one of jig joint 1 fixedly has internal diameter less than the boss 4 of jig joint internal diameter, left part at boss 4 has screw thread, there is screw thread in the right part outside at jig joint 1, the right-hand member inboard of jig joint 1 is the wide taper type in the left narrow right side, the right part of the left part of positioning sleeve 2 and jig joint 1 is fixed together by screw thread, and the seal ring 3 that holds out against by positioning sleeve 2 is arranged in the right-hand member inboard of jig joint 1.During use, the left end of steel pipe 7 is withstood on the boss 4, seal ring 3 and positioning sleeve 2 are enclosed within on the steel pipe 7, the right part of the left part of positioning sleeve 2 and jig joint 1 is fixed together and seal ring 3 held out against the effect that on jig joint 1, can reach the sealing and fixing steel pipe by screw thread, after having good positioning, the other end that uses the same method steel pipe 7 is installed on another jig joint 1, again two boss 4 are connected with two other jig joint 1 by pipe joint, can install many with steel pipe 7.Be convenient to dismounting after pressure testing finishes, therefore not only having improved working efficiency has also reduced cost of production.
As shown in Figure 1, in order to increase sealing, seal ring 3 is and the inboard corresponding taper type of the right-hand member of jig joint 1.
As shown in Figure 1, as required, the left end one of positioning sleeve 2 fixedly has the annular boss 5 that can withstand seal ring 3.
As shown in Figure 1, in order to increase sealing, be set with seal ring 6 on the positioning sleeve 2 in annular boss 5 outsides.
As shown in Figure 1, according to the needs that reality connects, the left part of boss 4 has internal thread or outside thread.
As shown in Figure 1, in order to seal, seal ring 3 is graphite packing seal ring.
