Description

Technical Field

[0001] This utility model relates to the field of power pipe technology, specifically a pressure-resistant CPVC power pipe. Background Technology

[0002] CPVC power pipes have excellent corrosion resistance, insulation and high temperature resistance, which can effectively protect cables from external environmental erosion and interference, extend the service life of cables and improve the stability of power systems. Therefore, they have been widely used in power engineering.

[0003] Traditional CPVC power pipes have certain limitations when connecting pipes of different diameters. Conventional connection methods such as socket connection and flange connection are not well adapted to diameter-changing connections, often requiring additional diameter-changing fittings, which increases the complexity and cost of the connection, and may also reduce the sealing and pressure resistance of the connection. Therefore, we propose a new type of pressure-resistant CPVC power pipe. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a pressure-resistant CPVC power pipe, including a power pipe body 1, a connection port 2 fixedly installed at one end of the power pipe body 1, a multi-diameter connector 3 at the other end of the power pipe body 1, a connection groove 21 opened in the connection port 2, the inner diameter of the connection groove 21 gradually increases from left to right in a stepped manner, the side wall surface of the connection groove 21 is provided with internal threads, and a drainage structure is provided inside the power pipe body 1;

[0021] The multi-diameter connector 3 includes a first connector 31, a second connector 32, and a third connector 33. The third connector 33 is fixedly connected to one end of the power pipe body 1. The outer surfaces of the third connector 33 and the second connector 32 are provided with external threads, and the inner sidewalls of the second connector 32 and the first connector 31 are provided with internal threads. The third connector 33 is connected to the internal thread of the inner sidewall of the second connector 32 through the external thread on its outer surface, and the second connector 32 is connected to the internal thread of the inner sidewall of the first connector 31 through the external thread on its outer surface.

[0022] In an optional embodiment: the drainage structure includes a threaded groove 4, which is formed on the inner wall of the power pipe body 1. The threaded groove 4 is threaded, and drainage holes 5 are formed at both ends of the threaded groove 4. The drainage holes 5 penetrate the side wall of the power pipe body 1, and the longitudinal section of the drainage holes 5 is vertical.

[0023] It should be noted that during the use of electrical conduits, water may accumulate inside the conduits for various reasons, such as rainwater seepage and condensation. The threaded groove 4 can guide the water inside the conduit to flow along the direction of the thread, playing a guiding role, so that the water can flow more smoothly to the drain hole 5, improving drainage efficiency and reducing the adverse effects of water accumulation inside the conduit on the conduit and cables.

[0024] In an optional embodiment, a debris-proof mesh 6 is fixedly installed on the inner surface of the drain hole 5. The debris-proof mesh 6 is made of stainless steel.

[0025] It should be noted that if impurities enter the drain hole 5 and accumulate inside the pipe, they may cause wear, corrosion and other adverse effects on the inner wall of the power pipe and the cable. The anti-impurity mesh 6 can intercept impurities, maintain a relatively clean environment inside the pipe, and help extend the service life of the power pipe and cable.

[0026] In an optional embodiment: a first sealing ring 7 is installed at each step of the connecting groove 21, and the first sealing ring 7 is made of rubber.

[0027] It should be noted that rubber has excellent elasticity and flexibility, which can fit tightly to the connection parts of CPVC power pipes, effectively preventing water, moisture, dust and other external substances from entering the pipe, avoiding damage to the cable, and ensuring safe and stable power transmission. It has a certain degree of elasticity and flexibility, making it easy to operate during installation and allowing for quick and accurate installation on CPVC power pipe connectors.

[0028] In an optional embodiment, a second sealing ring 8 is fixedly installed on the side end of the third connector 33 and the side end of the second connector 32, and the second sealing ring 8 is made of rubber.

[0029] It should be noted that rubber has excellent elasticity and flexibility, which can fit tightly to the connection parts of CPVC power pipes, effectively preventing water, moisture, dust and other external substances from entering the pipe, avoiding damage to the cable, and ensuring safe and stable power transmission. It has a certain degree of elasticity and flexibility, making it easy to operate during installation and allowing for quick and accurate installation on CPVC power pipe connectors.

[0030] In an optional embodiment: the power pipe body 1 includes an outer layer 11 and an inner layer 12, the inner layer 12 is fixedly installed on the inner surface of the outer layer 11, the outer layer 11 is made of chlorinated polyvinyl chloride, and the inner layer 12 is a metal composite layer.

[0031] It should be noted that chlorinated polyvinyl chloride (PVC) has excellent corrosion resistance, resisting the erosion of various chemicals and ensuring that the pipes are not corroded under different soil environments and harsh conditions. Its insulation properties are excellent, effectively isolating current, preventing leakage accidents, and ensuring the safety of power transmission. The metal material has extremely high strength and rigidity, able to withstand greater pressure and impact, providing the power pipe with strong pressure resistance and deformation resistance. The metal composite layer can also play a certain role in electromagnetic shielding, reducing the impact of external electromagnetic interference on power transmission.

[0032] In practical use, the working principle of this utility model is as follows:

[0033] When the power conduit body 1 needs to connect power conduits of different diameters, it connects the power conduit to be connected to the external thread of the third connector 33, or connects the internal thread of the second connector 32 to the external thread of the third connector 33, and then connects the external pipe to the external thread of the second connector 32. In this way, connectors of different diameters can be used to adjust the diameter of the interface. Then, the multi-diameter connectors 3 of different diameters are threaded to the connecting groove 21. The connecting groove 21 is designed in a stepped manner, so the multi-diameter connectors 3 of different diameters can correspond to the connecting grooves 21 of different diameters. During the use of the power conduit, water may accumulate in the pipe due to various reasons, such as rainwater seepage and condensation. The threaded groove 4 can guide the water in the pipe to flow along the direction of the thread, playing a guiding role, so that the water can flow more smoothly to the drain hole 5, reducing the adverse effects of water accumulation in the pipe on the pipe and cable.

[0034] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
