Abstract

The utility model relates to a pipe fitting for water central heating. The utility model comprises a pipe and a joint body connected with a pipe thread. The utility model is characterized in that the front end of pipe thread is provided with a cone. A conical surface matched with the cone of the pipe is arranged in the joint body. The front end of the conical surface of the joint body is provided with a flute. A sealing ring is positioned in the flute. Due to the adoption of the sealing structure of the conical surface and the sealing ring, the pipe fitting for water central heating has the advantages of reliable sealing performance, simple operation in construction, convenient installation, etc.

Description

Pipe fitting for water central heating
A kind of Pipe fitting for water central heating.
Existing Pipe fitting for water central heating, for example: fittings bodies such as free flow coupling, multiple way union, elbow, valve all adopt with pipe and are threaded.For the internal thread that prevents fittings body and the outside thread connection part of pipe leak, usually adopt ramie stripes, asbestos rope or material generation etc. as sealing material, it is wrapped in the screw thread circumference, fittings body is connected with pipe, exist poor sealing performance, sometimes leak, influence deficiencies such as pipeline working life.
The purpose of this utility model is to provide a kind of sealability reliable, simple to operate during construction operation, the Pipe fitting for water central heating being convenient to install.
The purpose of this utility model is realized by following technological scheme: a kind of Pipe fitting for water central heating, has pipe, the fittings body that is connected with pipe thread, its special way is: the front end at pipe thread is provided with cone, in fittings body, be provided with the conical surface that matches with the cone of pipe, conical surface front end at fittings body is provided with groove, is built-in with seal ring at groove.
Pipe fitting for water central heating of the present utility model is compared with existing Pipe fitting for water central heating, since pipe fitting of the present utility model change with ramie stripes, asbestos rope, material for etc. the traditional approach that seals as the filler in gap, threaded connection place, be sealed into the master, be sealed into secondary structure and adopt with seal ring with conical surface, it is reliable to have sealability, simple to operate during construction operation, be convenient to advantages such as installation.
The utility model is described in further detail to utilize an embodiment shown in the drawings below.
Fig. 1 is a structural representation of the present utility model.
With reference to Fig. 1, front end at pipe (4) screw thread is provided with cone (2), the conical surface (5) that matches with the cone (2) of pipe (4) is set in fittings body (1), and conical surface (5) front end in fittings body (1) is provided with groove, is built-in with seal ring (3) at groove.The groove of present embodiment is an annular, and seal ring (3) is an O type rubber ring.
