Description
Technical Field
The utility model relates to a sealing test's coupling, concretely relates to can outside pressure testing twine FRP pipe joint in succession.
Background
The continuous winding production technology of the glass fiber reinforced plastic pipeline is a new domestic process technology, and the performance of the product produced by continuous winding is superior to that of the product produced by fixed-length winding technology. Because of this characteristic of continuous winding production technology, continuously wound pipes are typically telescopically connected. The sleeve type joint is a joint form which is simple and convenient to install and can realize quick installation, and the aim of sealing is fulfilled by the rubber ring.
In order to verify the accuracy of field installation and the quality of products, the pipe joint needs to be subjected to a hydrostatic test after field installation to detect the tightness of the joint. However, in the case of the conventional sleeve joint, whether the joint is a full-width sealing ring or a double-rubber-ring sealing type, the on-site joint tightness test is difficult to perform, and the tightness test can be performed only by using special joint pressure testing equipment.
However, the above-mentioned purpose-built pressure testing devices have a number of disadvantages. Firstly, compressed gas is needed, the pressure of the gas generally reaches 5-7 kilograms, and the gas is a serious potential safety hazard for operators; secondly, because the pressure brought by the compressed gas needs to be borne, the equipment needs enough performance to support the pressure, so that the equipment is extremely heavy and difficult to operate, and the installation and test efficiency is greatly influenced; moreover, the test effect cannot reach the expected purpose, because of the limitation of compressed gas, the test pressure cannot be too high, and in addition, the field installation is complicated, and the pipeline may have deformation exceeding the expected deformation, so that the test effect is not ideal; finally, this test mode can only be performed internally, with high safety risks and difficult control.
Disclosure of Invention
In order to overcome the side deficiency of the prior art, the utility model provides a structural design is reasonable, but outside pressure testing, operation safe and reliable's winding glass steel pipe joint in succession. The utility model provides a joint form is different from full width formula sealed, also is different from two rubber ring seals, and its mode that adopts many rubber rings + copper mouth goes on, then reaches experimental purpose through the mode of outside pressure testing, can solve the various problems that the aforesaid exists.
The technical scheme is as follows: in order to realize the utility model discloses a purpose, the utility model discloses a technical scheme do:
a continuous winding glass steel pipe joint capable of being externally tested comprises a glass steel sleeve joint formed by continuous winding, a sealing ring mounting groove and an inhibition plug mounting groove which are formed in the glass steel sleeve joint, and a sealing ring and an inhibition plug which are respectively mounted in the sealing ring mounting groove and the inhibition plug mounting groove, wherein the sealing ring is positioned on two sides of the inhibition plug; the joint of the glass fiber reinforced plastic sleeve is provided with a pressure test hole, and the pressure test hole is connected with a pressure test copper nozzle;
the pressure test hole is positioned between the two sealing rings at the two sides of the suppression plug; the two sealing rings are arranged oppositely or in the same direction.
Above but continuous winding FRP pipe joint of outside pressure testing restrain the both sides of stopper and install 2 to 4 sealing washers respectively. Particularly preferably, 2 packing rings are attached to both sides of the suppression plug, respectively.
Preferably, the continuously wound glass fiber reinforced plastic pipe joint capable of being externally tested is characterized in that the copper nozzle for testing pressure is connected with a manual pressure testing pump.
Has the advantages that: the utility model provides a but continuous winding FRP pipe joint of outside pressure testing compares with prior art and has following advantage:
