The pipe joint commonly used at present has the following structures: set up the external screw thread on the coupling lateral wall to and set up the light wall on the coupling lateral wall, be provided with the boss that has the external screw thread on the light wall, the pipe fitting union commonly used is when being connected with the coupling that the external screw thread set up on the lateral wall, and pipe fitting union and coupling directly can keep good sealing performance, and when being connected with the coupling that the external screw thread set up on the boss, can't keep fine sealing performance between the light wall of pipe fitting union and coupling.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a convenient processing, and can also ensure its pipe fitting union who connects sealing performance after a lot of dismouting.
In order to achieve the above object, the utility model adopts the following technical scheme: a tubular union, comprising: the connector comprises a connector body with a channel, an external thread section and an internal thread section are arranged at the lower end of the connector body, the internal thread section is communicated with the channel, a first sealing ring groove is formed in the end portion of the external thread section, a second sealing ring groove is formed in the end portion of the internal thread section, sealing rings are arranged in the first sealing ring groove and the second sealing ring groove, a third sealing ring groove is formed in the top of the connector body, a sealing ring is arranged in the third sealing ring groove, an outwards convex shoulder is arranged on the connector body, a conical connecting portion is arranged between the convex shoulder and the connector body, a loose joint nut is sleeved on the convex shoulder, a conical hole capable of being matched with the conical connecting portion is formed in the loose joint nut, and a blocking mechanism is arranged on the connector body below the convex shoulder.
Further, in the pipe fitting union, a connecting hole is formed in the top of the union body, and the connecting hole is communicated with the passage.
Further, in the pipe union, a fourth sealing ring groove is formed in the tapered connecting portion, and a sealing ring is arranged in the fourth sealing ring groove.
Further, in the pipe fitting union, the blocking mechanism is a retainer ring, an annular groove is formed in the outer side wall of the joint body located below the shoulder, and the retainer ring is clamped in the annular groove.
The utility model has the advantages that: simple structure, processing convenience, application scope are wide, can be connected with the coupling of multiple not isostructure, connecting pipe, seal through the sealing washer, just so only need change the sealing washer just can ensure the sealing performance of being connected between pipe fitting union and coupling, the connecting pipe, relapse the dismouting can not influence its and coupling, the connecting pipe between sealing performance of being connected, prolonged life greatly.
