Abstract
The utility model discloses a flange for a thermoplastic pressure pipe. The flange consists of a plastic pressure pipe, a flange head, a sealing ring, a clamp ring, a tightening bolt and a fastening ring, wherein the flange head is provided with an inner housing; the inner housing is a round short pipe with a certain taper degree; the outer diameter of the front end of the inner housing is slightly smaller than the inner diameter of pipe material, and the outer diameter at the rear end of the inner housing is slightly larger than the inner diameter of the pipe material; the inner housing is provided with a convex-concave groove used for installing the sealing ring; and the clamp ring is a tapered round ring, and the inner diameter of the clamp ring is slightly larger than the outer diameter of the pipe material. During the installation of the flange, the clamp ring and the fastening ring are firstly sheathed on the pipe, then the inner housing is inserted in the pipe to the specified depth by external force, and finally the clamp ring is tightened, therefore a flange joint can be formed. The flange for the thermoplastic pressure pipe can realize construction on site only with simple universal tools and meet the construction requirements of various environments.

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of novel thermoplastic pipes flange is provided, and realizes utilizing simple tools at thermoplastic pressure tube termination upper flange, guarantee between tubing or tubing and pipe fittings between reliable the connection.
The utility model is achieved by the following technical programs:
A kind of thermoplastic pipes flange comprises the flange head, the seal ring that overlap in plastic pressure pipe, hold-down ring, retaining ring, tightening bolt, the band.
The interior cover of the flange head of cover is the round short tube with certain taper in the band, range of taper is 10 ° to 15 °, the front end external diameter of circle short tube is more smaller than the internal diameter of plastic pressure pipe, the rear end external diameter is more bigger than the internal diameter of plastic pressure pipe, simultaneously, the middle part of the interior cover of the flange head of cover is provided with tongue and groove to be used to install seal ring in the band.
The seal ring periphery is provided with hold-down ring, hold-down ring is the cone-shaped ring with oblique breach, anti-skidding double wedge is with in the inboard of hold-down ring, the outside of hold-down ring is a conical surface, the tapering in its outside is slightly larger than the tapering of the interior cover of the flange head of cover in the band, the range of taper of hold-down ring is 10 ° to 16 °, in addition, the space is arranged to be used to put into plastic pressure pipe between seal ring and the hold-down ring.
The hold-down ring periphery is provided with retaining ring, the inclined-plane of the inboard of retaining ring for matching with the outside of hold-down ring.
In general, be connected and fixed by tightening bolt between the flange head of cover in retaining ring and the band when plastic pressure pipe is big specification tubing, also can be connected and fixed between the flange head that overlaps in retaining ring and the band when plastic pressure pipe is small dimension tubing by screw thread.
Usefulness of the present utility model is:
The utility model provides a kind of thermoplastic pipes flange, only need utilize the simple tools just can be at thermoplastic pressure tube termination upper flange, simultaneously can also guarantee between tubing or tubing and pipe fittings between reliable the connection, do not need extra power supply and complicated instrument, be applicable to various special construction occasion and environment, have purposes and good practicability widely.
