Description

Technical Field

[0001] The utility model relates to the technical field of PE water supply pipes, specifically a socket-and-spigot type impact-resistant PE water supply pipe. Background Art

[0002] With the continuous acceleration of urbanization and the increasing requirements of people for the quality of domestic water and the reliability of water supply systems, water supply pipes play a vital role in the entire water supply infrastructure. Traditional cast iron pipes, galvanized steel pipes, etc., although excellent in performance, are heavy, have high transportation and installation costs, and poor corrosion resistance. Therefore, PE water supply pipes have stood out and become the current mainstream pipeline material. However, the existing PE water supply pipes have poor impact resistance due to the characteristics of the material. At the same time, when installed with socket joints, the connection is unstable and easy to loosen and fall off, resulting in poor sealing. In addition, when supplying water, the water may contain impurities, which can easily cause pipe blockage. Therefore, a socket-type impact-resistant PE water supply pipe is needed.

[0003] The existing socket-and-spigot type PE water supply pipe has the problems of poor impact resistance, poor connection stability and inability to filter during operation. Therefore, there is an urgent need for a socket-and-spigot type impact-resistant PE water supply pipe. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a socket-type impact-resistant PE water supply pipe to solve the problems of poor impact resistance, poor connection stability and inability to filter in the existing socket-type PE water supply pipe during use.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a socket-and-spigot type impact-resistant PE water supply pipe, comprising a spigot pipe, the outer wall of which is provided with a rubber buffer sleeve, and the inner wall of which is provided with a buffer groove.

[0006] A limit spring is installed on the inner wall of the socket tube, a limit rod is installed on the outer wall of the limit spring, a slot is provided on the inner side wall of the socket tube, an outer sealing ring is installed on the outer wall of the socket tube, a socket tube is installed on the outer wall of the socket tube, and an inner sealing ring is installed on the inner wall of the socket tube.

[0007] A filter is installed on the inner wall of the socket tube, an adjusting rod is installed on the bottom of the filter, a fixing plate is installed on the outer wall of the filter, a clamping rod is installed on the side wall of the fixing plate, a return spring is installed on the outer wall of the clamping rod, a clamping strip is installed on the side of the return spring away from the fixing plate, and a clamping block is installed on the outer wall of the clamping strip.

[0008] Preferably, the rubber buffer sleeve is glued to the socket tube, and the buffer grooves are distributed in a ring array with the central axis of the rubber buffer sleeve as the center.

[0009] Preferably, the limiting rod forms a telescopic structure with the socket tube through a limiting spring, and the limiting rod is symmetrically arranged with the central axis of the socket tube as the center.

[0010] Preferably, the limiting rod is fixedly engaged with the socket pipe, and the outer sealing ring is sleeved with the socket pipe.

[0011] Preferably, the outer wall diameter of the filter screen matches the inner wall diameter of the socket tube, the clamping strip forms a telescopic structure with the fixing plate through a reset spring, and the reset spring is sleeved with the clamping rod.

[0012] Preferably, the card strip is elastically arranged, and the card block is engaged with the card slot.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is provided with a rubber buffer sleeve and a buffer groove. The buffer groove inside the rubber buffer sleeve is hollow. When the surface of the rubber buffer sleeve is impacted by external force, the buffer groove is used to buffer the pressure, thereby preventing the spigot pipe and the socket pipe from being directly impacted by the external force, thereby extending the service life of the spigot pipe and the socket pipe;

[0015] 2. The utility model provides a limit spring, a limit rod, an outer sealing ring and an inner sealing ring. After the limit rod is pressed inward and the spigot pipe is inserted into the socket pipe to a suitable position, the limit rod is pushed out by the elastic force of the limit spring, so that the limit rod and the socket pipe are engaged and fixed, thereby avoiding shaking and deviation when the spigot pipe and the socket pipe are connected, and improving the stability of the connection between the spigot pipe and the socket pipe. The outer sealing ring and the inner sealing ring are used in conjunction to improve the sealing performance of the connection between the spigot pipe and the socket pipe.

[0016] 3. The utility model is provided with a filter screen, an adjusting rod, a fixing plate, a clamping rod, a reset spring, a clamping strip and a clamping block. The clamping strip is pressed inward, and then the filter screen is placed in the socket pipe. The filter screen is adjusted to a suitable position by pulling the adjusting rod. The clamping strip is squeezed outward by the elastic force of the reset spring. At this time, the clamping block is engaged and fixed with the clamping slot. The setting of the filter screen filters the fluid medium inside the pipeline to avoid blockage. When the filter screen needs to be disassembled for cleaning, the clamping strip is pressed inward and the adjusting rod is pulled outward. The disassembly and assembly are convenient.
