Description

Connecting part for geothermal pipes

Technical Field

The utility model relates to a pipe connection technical field especially relates to a geothermal pipe connects dress.

Background

The geothermal pipeline leads to a heat supply pipeline of a building heat inlet from a heat source, a plurality of heat supply pipelines form a pipe network, the design pressure of a heat supply hot water medium is less than or equal to 2.5MPa, and the design temperature is less than or equal to 200 ℃; the design pressure of the heating steam medium is less than or equal to 1.6MPa, the design temperature is less than or equal to 350 ℃, and the geothermal pipeline is a pipeline specially used for extracting underground heat. Because in the in-process of in-service use, the position that the pipe connection spare is connected is mostly the weak position of pipeline intercommunication, and its leakproofness is relatively poor, takes place the condition of leaking even damage easily.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects in the prior art and providing a geothermal pipe connecting piece.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a geothermal pipe connects dress, includes the support ring, the equal fixed mounting in both ends of support ring has the screwed pipe, and has all cup jointed the nut on two screwed pipes, fixed mounting has the screw ring on the nut is close to the inner wall of support ring, and screw ring and screwed pipe threaded connection, the sealing washer has been cup jointed on the screwed pipe, and has cup jointed the stainless steel clip on the sealing washer, fixed mounting has the lug on the nut inner wall, and lug and stainless steel clip looks adaptation.

Preferably, the side of the two nuts far away from each other is provided with a hexagonal groove.

Preferably, the support ring and the threaded pipe are both made of nylon materials.

Preferably, the sealing ring is made of a silica gel material.

The utility model discloses in, a geothermal pipe connects dress spare, the adoption is nylon material, meets water and can tighten up more when installing the connection of geothermal pipe, is difficult to the takeoff, and the staff's of can being convenient for operation, sealing washer adopt silica gel material more high temperature resistant.

Drawings

Fig. 1 is a schematic structural view of a geothermal pipe connecting fitting provided by the present invention;

fig. 2 is a schematic structural diagram of a part a of a geothermal pipe connecting fitting according to the present invention.

In the figure: 1 support ring, 2 screw caps, 3 hexagonal grooves, 4 threaded pipes, 5 threaded rings, 6 sealing rings, 7 stainless steel clips and 8 bumps.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a geothermal pipe connecting piece comprises a support ring 1, threaded pipes 4 are fixedly mounted at two ends of the support ring 1, nuts 2 are sleeved on the two threaded pipes 4, a threaded ring 5 is fixedly mounted on the inner wall, close to the support ring 1, of each nut 2, the threaded ring 5 is in threaded connection with the corresponding threaded pipe 4, a seal ring 6 is sleeved on each threaded pipe 4, a stainless steel clip 7 is sleeved on each seal ring 6, a convex block 8 is fixedly mounted on the inner wall of each nut 2, and the convex block 8 is matched with the stainless steel clip 7.

The utility model discloses in, hexagonal groove 3 has been seted up to one side that two nuts 2 kept away from each other.

The utility model discloses in, support ring 1 and screwed pipe 4 all adopt the nylon material to make.

The utility model discloses in, sealing washer 6 adopts silica gel material to make.

In the utility model, the nylon material is adopted, when the geothermal pipe is installed, the nylon material is tightened up when meeting water, the pipe is not easy to fall off, the support ring is transparent, so that an installer can conveniently see the position of the pipe, the stainless steel clip is used for clamping to play a role in preventing the pipe from falling off, and the sealing ring is made of silica gel material and is more resistant to high temperature;

during the use, insert the pipeline in the screwed pipe, then spiral shell nut 2, nut 2 drives screw ring 5 and rotates on the screwed pipe, and simultaneously, the lug extrudees the stainless steel clip, and the stainless steel clip presss from both sides tight sealing washer, simultaneously, drives the screwed pipe and presss from both sides tight pipeline.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
