Abstract

A self-inspection type three-way copper pipe fitting, belonging to the technical field of manufacturing copper pipe fittings, mainly consists of a joint body (2) with three interfaces (6), placed in the interface (6) with an O-shaped sealing ring (3 ) of the sealing groove (4), opened in the detection hole (5) in the sealing groove (4) and so on. When in use, put O-rings of corresponding specifications on the sealing grooves in the three interfaces of the joint body, insert the pipes into the three interfaces, and press them with a special presser. If there is a missing card during use, there will be obvious leakage at the detection hole 5 during the pressure test, and it will be found that the card is missing. It can effectively avoid the failure to be discovered in time during the pressure test, and the leakage phenomenon will be found in the future use.

Description

Self-inspection tee copper pipe fittings

technical field

The utility model relates to a self-inspection type three-way copper pipe fitting, which belongs to the technical field of manufacturing copper pipe fittings.

Background technique

The existing clamping type three-way copper pipe fitting is composed of a joint body. The interface of the joint body is provided with a protruding sealing groove, and a sealing ring is arranged in the groove. The two sides of the sealing groove are sockets. When using, the pipe is inserted into the interface and sealed. Inside the circle, press it with a special presser. However, in the process of use, there is often a phenomenon of card leakage, and it is not discovered in time during the pressure test, and leakage is found in future use.

Contents of the invention

The purpose of the utility model is to provide a self-inspection type three-way copper pipe fitting with reasonable design, simple structure, convenient and practical operation, and reliable operation.

The utility model is a self-inspection type three-way copper pipe fitting, which includes a joint body with three interfaces, and is placed in a sealing groove with an O-shaped sealing ring in the interface, and is characterized in that a detection hole is opened in the sealing groove.

The utility model has a reasonable design, and a detection hole is respectively added to the three protruding sealing grooves of the existing clamping type tee. Leakage phenomenon.

Description of drawings

Fig. 1 is a half-sectional view of the overall structure of the utility model;

Fig. 2 is a cross-sectional view of the A-A plane structure shown in Fig. 1 .

In the figure, 1 is a pipe, 2 is a joint body, 3 is an O-ring, 4 is a sealing groove, 5 is a detection hole, and 6 is an interface.

Detailed ways

The utility model is mainly composed of a joint body 2 with three interfaces 6, a sealing groove 4 with an O-shaped sealing ring 3 placed in the interface 6, a detection hole 5 opened in the sealing groove 4, and the like.

When in use, put O-rings 3 of corresponding specifications on the sealing grooves 4 in the three interfaces 6 of the joint body 2, insert the pipe 1 into the three interfaces 6, and press with a special presser. If there is a missing card during use, there will be obvious leakage at the detection hole 5 during the pressure test, and it will be found that the card is missing. It can effectively avoid the failure to be discovered in time during the pressure test, and the problem of leakage will be found in the future use.

Claims (1)

1, a kind of self-checking type triplet copper pipe spare comprises the fittings body (2) with three interfaces (6), places the seal groove (4) of band O RunddichtringO (3) in the interface (6), it is characterized in that offering in the seal groove (4) detection hole (5).
