Abstract

The utility model discloses a shockproof and leakproof pipe fitting, comprising a pipe fitting body and a locking nut matched on a bell and spigot opening of the pipe fitting body. The utility model is characterized in that a clamp spring and a pressing pad are successively matched between the locking nut and the bell and spigot opening, wherein, the inner wall of which is matched with a sealing part. The utility model has the advantages of convenient operation, wide application range, and good shockproof and leakproof performances.

Description

The anti-fistulae spare of antidetonation

The utility model relates to a kind of link of pipeline, especially a kind of water supply line link.

It all is that the hank knotting mouth connects that traditional pipeline connects.Along with the forbidding of Coating Steel Pipe, and after people knew that the metal inner surface water pipe can't be kept out the intrusion of the disinfectors such as tri-chlorination alkane in the tap water, countries in the world were all at the anti-corrosion composite material of development, as water supply line.The pipeline kind is numerous on the market, aluminium-plastic composite pipe is arranged, galvanized steel is moulded pipe again, copper pipe outsourcing plastic tube, ultra-thin-wall red copper plastic composite pipe and ultra-thin-wall plastic stainless-steel composite-tubes etc., mould the connection of pipe except galvanized steel again and still adopt the connection of hank knotting mouth, the even employing cutting ferrule of all multiple tubes is connected with the clamp band type pipe fitting.Though regrettably the plastics in the Coating Steel Pipe have solved the anti-corrosion problem of pipeline, the vital wound of corrosion is not still escaped in the attachment portion of pipe fitting.And those FERRULETYPE, clamp band type pipe fitting more or less all exist the hidden danger of infiltration on the market.Let alone antidetonation.Because the problem of the technical existence of pipe fitting, make manyly to have developed, colory pipeline, as ultra-thin-wall stainless steel and plastic composite pipe, luxury ultra-thin-wall red copper and plastic composite pipe, or the like novel pipeline can't introduce to the market in a large number.

It is a kind of easy to use that the purpose of this utility model is to provide, widely applicable and have an anti-pipe joint that leaks of better antidetonation.

To achieve these goals, the utility model adopts following technological scheme: the anti-fistulae spare of a kind of antidetonation, comprise main pipe body and the locking nut that is configured on the main pipe body joint socket, it is characterized in that: be furnished with jump ring and compress gasket between locking nut and joint socket successively, the inner wall arrangement Sealing of joint socket.

Good effect of the present utility model is: the structure of this design can antidetonation, the anti-leakage, and Sealing adopts silica gel, can prevent to expand with heat and contract with cold, and health is reliable.Particularly this pipe fitting is not only applicable to drinkable water, can also change ferrule-type pipe fitting and can not be used for the defective that gas pipeline connects.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is that preferred embodiment structure of the utility model is formed schematic representation;

Fig. 2 is that preferred embodiment pipeline of the utility model connects generalized section.

See also illustrated in figures 1 and 2.The utility model is made up of main pipe body 10 and the locking nut 20 that is configured on the three-dimensional joint socket 11 of pipe fitting, and joint socket adopts with locking nut and is threaded.11 of locking nut 20 and joint socket are furnished with jump ring 30 and compress gasket 40 successively, the inner wall arrangement Sealing 50 of joint socket 11, and the sealing part adopts the silicone rubber material.Main pipe body of the present utility model and locking nut are made with metal material.Main pipe body 10 can be multiple shape and structure, as being two logical, threeway, straight peen, elbow etc.During installation on the position of pipeline 60 regulation through rolling or pressing, form a groove 61, overlap upper locking nut 20, jump ring 30, compress gasket 40 and silicone rubber seal 50 successively, insert pipe fitting joint socket 11 again, locking nut 20 then, make parts such as pipeline groove 61, jump ring 30 form one, form a combination that is difficult to break away from.

Claims
