Technical field

This utility model is related to a kind of pipe joint, specifically refers to that a kind of two hold a flat threeway retaining connector.

Background technology

Three-way pipeline joint, is indispensable equipment in tubing, plays important in whole tubing Effect.Traditional three-way pipeline joint, is usually made up of the valve body and the adapting pipe for being connected to valve body right part of upper and lower insertion, The upper and lower end of valve body covers rubber ring by valve gap.When using, directly outside connecting tube is inserted into rubber ring through valve gap It is interior, so as to connect with valve body.With the passage of use time, the connecting tube of insertion easily departs from rubber ring, causes pipeline to connect , easily there is the problem that medium spills in the poor sealing of head, and to technical staff's maintenance great inconvenience is brought.

Utility model content

This utility model provides a kind of two and holds a flat threeway retaining connector, and its main purpose is to overcome existing three-way pipeline Joint is with connecting tube as the passage of use time can occur between the two the problem of disengaging.

In order to solve above-mentioned technical problem, this utility model is adopted the following technical scheme that and is achieved：

A kind of two hold a flat threeway retaining connector, including the valve body of a upper and lower insertion, and the right part of the valve body is provided with one and valve Body is connected and horizontally disposed adapting pipe, is arranged with rubber ring and lower rubber ring in the upper and lower part of the valve body respectively, described The bottom of the top of upper rubber ring and lower rubber ring is stretched out outside valve body, the bottom surface of the top surface of the upper rubber ring and lower rubber ring Fold respectively and be provided with elastic metallic trim ring and lower elastic metallic trim ring, the upper elastic metallic trim ring and lower elastic metallic trim ring set Having can make the breach of its each self expandable, and the inwall of the upper elastic metallic trim ring and lower elastic metallic trim ring is equipped with respectively multiple Upper and lower arranged for interval and inwardly protruded upper anticreep stricture of vagina and lower anticreep stricture of vagina, the upper anticreep stricture of vagina and lower anticreep stricture of vagina are respectively obliquely Arrange with oblique Shangdi, the top of the upper elastic metallic trim ring and the bottom of lower elastic metallic trim ring are covered with respectively upper and lower The bonnet, and bottom flange of insertion, the bonnet, and bottom flange it is detachably connected with valve body, the right-hand member of the adapting pipe It is provided with adpting flange.

Further, the upper inside wall and lower inner wall of the valve body is equipped with intilted first conical surface, it is described on The top of the bottom of rubber ring outer peripheral face and lower rubber ring outer peripheral face is equipped with bores with second that corresponding first conical surface is adapted Face, the upper rubber ring inwall and lower rubber ring inwall are equipped with sealing screw thread, the outer peripheral face of the upper elastic metallic trim ring The outer peripheral face bottom of top and lower elastic metallic trim ring is equipped with outward-dipping having three pyramidal faces, the inner peripheral surface of the bonnet, The inner peripheral surface bottom of top and bottom flange is equipped with the 4th conical surface being adapted with corresponding having three pyramidal faces.

Further, the angle between the first, second, third and fourth conical surface and vertical plane is 45 °.

Further, the bonnet, and bottom flange are bolted with valve body.

Further, the valve body, adapting pipe, adpting flange, upper elastic metallic trim ring, lower elastic metallic trim ring, upper valve Lid and bottom flange are made by spheroidal graphite cast-iron.

Further, the valve body, adapting pipe and adpting flange are integrally formed.

From the above-mentioned description to this utility model structure, compared to the prior art, this utility model has following excellent Point：This utility model is rational in infrastructure, design is ingenious, and when the upper and lower end of valve body accesses connecting tube, the connecting tube of upper end can wear Bonnet, and upper elastic metallic trim ring are crossed, is inserted in rubber ring and is connected with valve body；The connecting tube of lower end may pass through down Valve gap and lower elastic metallic trim ring, are inserted in lower rubber ring and connect with valve body, then again consolidate valve body with upper and lower valve gap Fixed connection, realizes connection procedure of the present utility model.The upper anticreep stricture of vagina and lower anticreep stricture of vagina set with oblique Shangdi obliquely respectively Put so that the direction that connecting tube is extracted is in opposite direction with upper and lower anticreep stricture of vagina, when connecting tube has the trend of outside disengaging, upper, Lower anticreep stricture of vagina can be engaged connecting tube, prevent connecting tube from departing from rubber ring.Relative to traditional pipe joint, this utility model The energy connecting tube that effectively fixed valve body upper and lower end is accessed so that the sealing of joint is better, can effectively solve the problem that tradition There is the problem of medium omission in pipe joint, so as to decrease the number of times of technical staff's maintenance.
