Description

A thin-walled stainless steel water pipe expansion joint

technical field

The utility model relates to a thin-wall stainless steel water pipe, in particular to a thin-wall stainless steel water pipe telescopic connector.

Background technique

Water pipes are water supply pipes. Modern decoration water pipes are built with buried walls. There are three types of water pipes. The first type is metal pipes, such as hot-dip cast iron pipes with plastic lining, copper pipes, and stainless steel pipes. The second category is plastic composite metal pipes, such as plastic composite steel pipes, aluminum-plastic composite pipes, etc. The third category is plastic pipes, such as PB, PP-R. Metal pipe stainless steel pipe has the characteristics of safety, hygiene, health, durability, etc., eliminates the pollution caused by plastic pipes, and the price is much cheaper than traditional steel pipes. It is the preferred water pipe material in the contemporary era.

In the connection of water channels, different stainless steel water pipe shapes are usually required to meet actual needs, or to replace stainless steel water pipes of different specifications and sizes according to actual needs. The traditional method is that one of the stainless steel water pipe rings is internally threaded, and the other stainless steel water pipe is externally threaded. , mutually screwed and fixed, but this method must additionally produce or purchase a separate threaded barrel, which increases the cost. There are other methods that weld the stainless steel water pipes that need to be connected to each other. This method needs to measure the distance between the welded stainless steel water pipes clearly, and there must be no slight difference. Even if the length of the corresponding stainless steel water pipes is measured and cut, the welding Seamless welding must be ensured during the process, otherwise leakage will occur and cause huge losses. In order to solve the above drawbacks, it is urgent to propose a thin-walled stainless steel water pipe telescopic connector.

Utility model content

The purpose of the utility model is to overcome the disadvantages of the existing technology, to provide a simple structure, uncomplicated manufacturing process, reduce the pressure caused by the length error, easy to operate, effectively improve the connection efficiency, and ensure the tightness of a thin Wall stainless steel water pipe expansion joints.

The purpose of this utility model is achieved in the following manner: a thin-walled stainless steel water pipe telescopic connector, characterized in that it includes a stainless steel main pipe and a stainless steel telescopic pipe set outside it, and the pipe wall of the stainless steel telescopic pipe protrudes outwards A sealing ring is formed, a sealing ring is installed in the sealing ring, and the sealing ring seals the gap between the stainless steel telescopic tube and the stainless steel main pipe.

The outer diameter of the stainless steel main pipe is less than or equal to the inner diameter of the stainless steel telescopic tube.

The sealing ring is integrally formed with the stainless steel telescopic tube.

The sealing ring is made of silicone material.

The beneficial effects of the utility model are: 1) The structure is simple, the production cost is low, and the market competitiveness is improved. 2) There is no need to deliberately cut the stainless steel main pipe of a specific length, the stainless steel main pipe can be properly lengthened to reduce errors. 3) Use the sealing ring in the sealing ring to fill the gap between the stainless steel telescopic tube and the stainless steel main pipe. The structure is simple and the manufacturing process is not complicated, which not only greatly reduces the production cost, but also is convenient and not cumbersome to operate, effectively improving the connection efficiency and ensuring the stainless steel water pipe. of tightness.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is specifically further described. A thin-walled stainless steel water pipe telescopic connector, characterized in that it includes a stainless steel main pipe 1 and a stainless steel telescopic pipe 2 set outside it, the pipe wall of the stainless steel telescopic pipe 2 protrudes outward to form a sealing ring 3, and the sealing ring 3 A sealing ring 4 is installed inside, and the sealing ring 4 seals the gap between the stainless steel telescopic tube 2 and the stainless steel main pipe 1 .

The outer diameter of the stainless steel main pipe 1 is less than or equal to the inner diameter of the stainless steel telescopic tube 2 .

The sealing ring 3 is integrally formed with the stainless steel telescopic tube 2 .

The sealing ring 4 is made of silicone material.

Working principle: In this case, the pipe wall of the stainless steel telescopic tube protrudes outward to form a sealing ring, and the sealing ring is installed in the sealing ring. When the stainless steel main tube extends into the stainless steel telescopic tube and passes through the inner ring of the sealing ring, the caliper is used to clamp the outer surface of the sealing ring, so that the sealing ring is pressed inward, and the sealing ring seals the gap between the stainless steel telescopic tube and the stainless steel main tube .

Compared with the traditional technology, the utility model does not need to specially cut the stainless steel main pipe of a specific length, the stainless steel main pipe can be stretched, and the user can freely adjust its length to achieve the best use length. After the stainless steel main tube is connected to the stainless steel telescopic tube, there is no need to use traditional welding, only need to apply pressure to the sealing ring, and the sealing ring in the sealing ring can be used to fill the gap between the stainless steel telescopic tube and the stainless steel main tube, the structure is simple, The production process is not complicated, which greatly reduces the production cost, and the operation is convenient and not cumbersome, which effectively improves the connection efficiency and ensures the tightness of the stainless steel water pipe
