Abstract
The utility model discloses a high-sealability high-pressure pipe joint, which is innovatively characterized in that the pipe joint comprises a joint body, a connecting pipe, a gland nut and a resilient pad, wherein the connecting pipe is cooperatively connected with the joint body, the gland nut is used for closely connecting the joint body with the connecting tube, the high-pressure pipe joint is made of 45 high-quality carbon steel, a sealing component is arranged between the joint body and the connecting pipe, one end of the gland nut is provided with an internal thread, the other end of the gland nut is provided with a pressing component, the inner circular end face of a pressing body is an inner circular conical surface, the inner circular conical surface of the pressing body is provided with an arc groove, the inner circular end face of the joint body is an inner circular conical surface, the inner circular conical surface of the joint body is provided with another arc groove, and the two ends of the resilient pad are respectively arranged in the arc groove on the inner circular conical surface of the pressing body and the another arc groove on the inner circular conical surface of the joint body. Through arranging the sealing component between the joint body and the connecting tube, the sealability of the pipe joint is improved; due to the setting of the resilient pad, the connection of the high-pressure pipe joint can be effectively prevented from being loosened in the process of shaking, and then the sealing reliability is further improved; the high-pressure pipe joint is simple in structure and convenient to install.
Description
Technical field
The utility model relates to a kind of high-pressure pipe connector, is specifically related to a kind of can effectively preventing and connects and become flexible when vibrations, has the high-pressure pipe connector of high leak tightness.
Background technique
Extensive use along with development and the non-metal kind high-pressure delivery pipeline of conveyance conduit, technical requirements to high voltage direct connection for bbreather pipe is also more and more higher, because high voltage direct is threaded a pipe, joint is the core component of conveying high-pressure fluid pipeline, it is directly connected to the Performance and quality of conveying high-pressure fluid pipeline, in known technology, existing high-pressure pipe connector is to be mainly shaped with connecting thread by a termination, axle center is shaped with high-pressure pipe connector main body and seal ring or the seal ring of through hole, overcoat connects gland pipe again, and in high-pressure pipe connector main body, be shaped with annular pawl and form, but limit by its structure, its complicated integral structure, cost is high, connect loaded down with trivial details, and sealing is poor, in actual fed highly pressurised liquid process, easily cause leakage.State Patent Office's disclosed utility application on July 26 " high-pressure pipe connector " in 1989, it comprises union body with the gland nut being connected with pipe joint screw thread and is pressed in the pipe box that also can move with gland nut on flared steel pipe, also comprises a center fixture with the large and small conical surface and two " O " shape O-ring seals.Center fixture is arranged between union body inward hole slope and the enlarging of flared steel pipe, large and small two conical surfaces of center fixture contact with enlarging and the union body inward hole slope of flared steel pipe respectively, two " O " shape O-ring seals be arranged on respectively on the large and small conical surface of center fixture with fixed groove in.Although this utility model patent has solved the not good problem of flared fitting sealing effect, also exist component more, assembling and the problems such as trouble are installed all, and high pressure easily causes pipe joint to become flexible.
Summary of the invention
The purpose of this utility model is to solve deficiency of the prior art, provides a kind of simple in structure, has the high-pressure pipe connector of high leak tightness.
For solving the problems of the technologies described above, the utility model adopts following technological scheme to realize:
A high-pressure pipe connector for high leak tightness, its innovative point is: high-pressure pipe connector adopts 45 Fine Steel Casting irons to make, and comprises gland nut, fittings body, adapter and resilient pad;
One gland nut, one end arranges the internal thread being connected with fittings body, and one end has the press body of compacting resilient pad, and press body inner circle end face has internal conical surface, on press body internal conical surface, arc groove is set;
One fittings body, the outside thread that the setting of fittings body head end and gland nut internal thread match, fittings body with take over relative end face on be provided with Sealing, the inner circle end face of fittings body has internal conical surface, and another arc groove is set on internal conical surface;
One takes over, and takes on the end face relative with fittings body and is provided with draw-in groove in the corresponding position of the Sealing with joint;
One resilient pad, for bowl-type metallic elastic pad, one end of resilient pad is arranged in the arc groove of press body inner side of gland nut, with press body close contact, the other end is arranged in another arc groove of internal conical surface of fittings body, with internal conical surface close contact, the surperficial close contact of the bottom of resilient pad and adapter.
Described high-pressure pipe connector is the plated item through the antirust processing of plating.
The beneficial effects of the utility model: the utility model high-pressure pipe connector adopts 45 Fine Steel Casting irons, it has good plasticity, intensity, fabulous voltage endurance capability; By Sealing is set on fittings body, Sealing makes together with the surface of contact of fittings body and adapter fits tightly, to improve sealability; The setting of metallic elastic pad, can effectively prevent that high-pressure pipe connector from connecting when vibrations loosening, further improves sealing reliability, simple in structure, easy for installation.
