Hough section is a pipe leak stopper.Hough section and socket is hough section of pipeline repair device, socket hough section is on the socket of the two pipe joint leakage repair device, hough section is to repair the part other than the socket of the device, the device has simple structure only two ontology and two pieces of rubber mat, convenient installation, only the two ontologies involution in leaks tight nut can complete the repair of pipe,This device can not only save the time of water shutdown, but also reduce the cost of emergency repair.
The performance characteristics:
1. Using the combination of plastic contact seal and elastic contact seal technology, suitable for all kinds of materials of the pipeline, effectively control the leakage problem of the medium.
2. The site use effect is good, can do watertight, the use of block structure, the site construction speed is fast, no need to stop water, construction excavation is small, only need to dig a small pit can be operated, save a lot of manpower and material resources and time, quickly achieve the purpose of plugging.
3. Working pressure: 0.25-1.0MPa, suitable for all kinds of cast iron pipe and cement pipe, PVC pipe leakage maintenance.Product specifications are complete, applicable to a variety of national standard pipe diameter, non-standard processing can be customized.
There are many types of Haugh joint pipe fittings, including the following main types:
1. Bending pipe fittings, we contact more, is the straight pipe into different radius of curvature of the elbow, such as elbow, elbow and so on;
2 with flange and round flange pipe fittings, the former refers to the tube end to the inside or outside convex, the latter refers to the formation of a raised or grooved pipe fittings in the circumferential direction of the pipe;
3. For pipe fittings with crimping and sealing, increase the total strength of the pipe end to crimping the outer or inner side of the pipe or sealing the end of the pipe;
4. Enlarged pipe fittings, according to the requirements of the end or a part of the pipe fittings to expand into various shapes of pipe fittings;
5. Variable diameter pipe fitting means that the diameter of the pipe end or a department on the pipe decreases;
6. Variable wall thickness of pipe fittings refers to the change of wall thickness along the length of the pipe;There are also many kinds of pipe fitting processing methods.Many also belong to the category of mechanical processing, the most used is the stamping method, forging method, roller processing method, rolling method, bulging method, stretching method, bending method, and combined processing method.Pipe fitting processing is the organic combination of machining and metal pressure machining;
7. Change the section of the pipe fitting, according to the requirements, the circular section into square, oval, polygon and so on.
Mechanical properties of
It has excellent casting, cutting and wear resistance and certain elasticity. It is widely used in the manufacture of crankshafts, gears, pistons and other advanced castings as well as a variety of mechanical parts. The precision of Haff joint is high, generally up to CT4-6 (CT10~13 for sand casting, CT5~7 for die casting)., of course, as a result of the investment casting process is complex, the factors affected the accuracy of hough section size is more, such as mold material shrinkage and deformation of casting, shell in the process of heating and cooling line quantity change, alloy of shrinkage and deformation of castings in the solidification process, so the average size of investment castings although higher accuracy,But its consistency still needs to be improved (using medium and high temperature wax castings size consistency to improve a lot).
Hough section ring belongs to pipeline repair technology, specifically involves a hough section sealing ring, including Settings on both sides of the sealing ring, sealing ring connection Settings are referred to in each end of the first second sealing strip, sealing strip and described the first sealing strip symmetrical about the centerline of the sealing ring after the position and the position of the second sealing strip,That first sealing strip and second sealing strip on the centerline of the sealing ring is not relative, said hough section of the sealing ring this set mode makes the first sealing strip and the second sealing strip in the opposed when installation snuggle incomplete or do not stick together, through the sealing strip and sealing strip seal cooperate to achieve hough section of shell structure,Thus, the combination of shell and sealing strip greatly improves the high pressure resistance and water hammer resistance performance of the Haffle joint and ensures the sealing performance of the Haffle joint.
1. It does not need power supply and is not limited by distance valve. It works under pressure, especially suitable for underground operation in coal mine.
2. Under the normal operation conditions of the pipeline, the connection part has a sealing ring, which will not cause water leakage, oil leakage and other environmental pollution.
3. Suitable for underground engineering, chemical industry, water supply, underground various pipelines, etc.In the absence of power supply, complete temporary or permanent piping with pressure connection and water intake works.
4. Under the normal operation condition of 2 to 6 inches in diameter pipeline, the positioning connection can be quickly completed on any part of the pipeline without cutting off water or oil.It has the characteristics of high strength, small volume and easy operation.
5. The quick nozzler adopts manual operation without stopping production. It is applied to all kinds of water and oil pipelines without using any power.
6. It is mainly used for underground rescue and rescue in coal mines to drill water quickly on the pipeline to ensure the need of direct water fire extinguishing.
7. After use, close the gate valve and it can be restored to its original state.
