Abstract
The invention relates to a pipe joint with a better sealing performance. The pipe joint with the better sealing performance comprises a joint body and connecting pipe, wherein an outer screw thread is arranged at the end part of the joint body; a blocking shoulder is arranged at the end part of the connecting pipe; a connecting piece between the joint body and the connecting pipe is an specially-shaped nut; a groove is also arranged at the end face of the connecting pipe; and a sealing piece which is arranged in the groove and comes into contact with the end face of the joint body is arranged between the joint body and the connecting pipe. The pipe joint with the better sealing performance disclosed by the invention has the advantages that: as the sealing piece, which is made of materials, such as red copper and the like and has better elasticity, has a good sealing effect, the pipe joint with the better sealing performance is particularly suitable for malicious environments, such as hydraulic equipment in a continuous casting workshop, with high temperature, high pressure, dustiness and the like.
Description
Technical field
The present invention relates to the better pipe joint of a kind of sealability.
Background technique
At present, many equipment use high-pressure medium as the transmission of power medium.At smelting industry, commonly used to medium transfer units such as hydraulic oil pipelines.Its working environment usually is the rugged environment of high temperature, many dirt, and the pressure requirement is also high, reaches 35Mpa, in the practice, waits and reduces pipeline medium and pressure leakage through using Stainless Steel Tube, high temperature high voltage resistant pipe, and effect is better, but the leakage at pipe joint place still exists.Original pipe joint comprises that the end is provided with the adapter and the special-shaped nut with matching of one section externally threaded fittings body, shouldered; The endoporus of special-shaped nut is a step hole; Macropore inwall processing oil internal thread, with the outside thread of fittings body group with, and can hold the end shoulder block of adapter; Aperture is the hole of inner wall smooth; With the adapter Spielpassung; Pipe joint relies on the pretightening force of nut that fittings body is compressed anti-heads with the end face that contacts, even but select machining accuracy, assembly precision is good, the sealed material performance is good pipe joint for use, the effect that the joint seals still is not an ideal very yet; And having influence on the normal operation of the equipment that uses this pipeline frequently, the leakage of medium also can bring environmental pollution problem.For example, for the casting machine system, hydraulic oil, oil leak get into water treatment system, increase the water treatment carrying capacity, and have brought unfavorable factor for later process.Such as, greasy dirt is too many, and the water treatment imperfection gets into cooling equipment through pumping system, causes faults such as spray nozzle encrustation obstruction, body encrustation.
Summary of the invention
The purpose of this invention is to provide the better pipe joint of a kind of sealability, not really desirable to overcome original pipe seal effect, can have influence on the normal operation of the equipment that uses this pipeline frequently, the leakage of medium also can bring the deficiency of environmental pollution problem.
The objective of the invention is to realize through following technological scheme:
The better pipe joint of a kind of sealability comprises fittings body and adapter, and the end of said fittings body is provided with outside thread; The end of taking over is provided with shoulder block; Link between fittings body and the adapter is special-shaped nut, and the end face of adapter also is provided with groove, is provided with Sealing between said fittings body and the adapter; Sealing places in the groove, contacts with the end face of fittings body.
Beneficial effect of the present invention is: materials such as application red copper are processed elasticity better seal part, and good sealing effect is arranged, and are particularly useful for rugged environment such as high temperature, high pressure, many dirt, on the hydraulic equipment like the continuous casting workshop.
Description of drawings
According to accompanying drawing the present invention is done further explain below.
Fig. 1 is the plan view of the better pipe joint of the described sealability of the embodiment of the invention.
Among the figure:
1, fittings body; 2, Sealing; 3, take over; 4, special-shaped nut; 5, external thread section; 6, shoulder block; 7, groove.
Embodiment
As shown in Figure 1, the better pipe joint of the described a kind of sealability of the embodiment of the invention comprises fittings body 1 and takes over 3; The end of said fittings body 1 is provided with one section outside thread 5, and the end of adapter 3 is provided with shoulder block 6, and fittings body 1 and the link of taking between 3 are special-shaped nut 4; Take over the groove 7 that 3 end face also is provided with annular, said fittings body 1 and take over and be provided with the Sealing 2 that red copper is processed between 3, Sealing 2 place fittings body 1 and take in the groove 7 that 3 end faces are provided with; Contact with the end face of fittings body 1; Rely on the red copper good ductility, under the pretightening force effect of special-shaped nut 4, Sealing 2 is close together with fittings body 1 and the surface of contact of taking over 3; Almost very close to each other, still have good sealing effect when using under the high pressure conditions thereby reach.
During concrete the use, can also can respectively fittings body or adapter be connected with T-shape pipe or " ten " font pipe etc., just can connect into needed pipeline in the end of straight tube welding upper connection body or adapter.
The present invention uses materials such as red copper and processes elasticity better seal part, and good sealing effect is arranged, and is particularly useful for rugged environment such as high temperature, high pressure, many dirt, on the hydraulic equipment like the continuous casting workshop.
