Description

Technical Field

[0001] The utility model relates to the field of pipelines, in particular to a pipe fitting with high anti-freezing performance. Background Technique

[0002] Pipe fittings are a general term for components in a pipeline system that play roles such as connection, control, direction change, flow diversion, sealing, and support. They are an important part of connecting pipelines. According to the connection method, they can be divided into four categories: socket fittings, threaded fittings, flange fittings, and welded fittings. They are an indispensable part of the pipeline system, ensuring that the pipeline can safely and effectively transport fluids (such as water, gas, oil, etc.).

[0003] In cold regions, pipe fitting systems for water supply, heating, etc. often face the risk of freezing and cracking. Due to the shrinkage of the material itself and the ice expansion of water, pipe fittings are prone to brittle fracture, water leakage and other problems, seriously affecting the service life and safety of pipe fittings. Therefore, those skilled in the art have provided a pipe fitting with high anti-freezing performance to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pipe fitting with high anti-freezing performance to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A pipe fitting with high anti-freezing performance includes a pipe fitting main body. A waterproof layer is fixedly connected to the inner wall of the pipe fitting main body. An electric wire heating layer is fixedly connected to the inner wall of the waterproof layer. A pipe core is fixedly connected to the inner wall of the electric wire heating layer. A mounting seat is fixedly connected to the inner wall of the pipe core. A temperature sensor is fixedly connected to the bottom surface of the mounting seat. An inner pressure-resistant layer is arranged inside the pipe core. A middle heat-insulating layer is fixedly connected to the outer surface of the inner pressure-resistant layer. An anti-freezing layer is fixedly connected to the outer surface of the middle heat-insulating layer.

[0007] As a further scheme of the utility model: Mounting plates are fixedly connected to both the left side surface and the right side surface of the pipe fitting main body. A group of positioning holes are opened on the side surfaces of the two mounting plates away from each other. Fixed pins are threadedly connected to the inner walls of one group of the positioning holes.

[0008] As a further scheme of the utility model: Sealing gaskets are fixedly connected to the side surfaces of the two mounting plates away from each other. The material of the sealing gaskets is rubber.

[0009] As a further scheme of the utility model: An anti-corrosion coating is fixedly connected to the outer surface of the pipe fitting main body. A protective sleeve is sleeved on the outer surface of the pipe fitting main body.

[0010] As a further solution of the present utility model: a marking parameter plate is provided on the front of the pipe fitting main body, and the back of the marking parameter plate is fixedly connected to the front of the pipe fitting main body.

[0011] As a further solution of the present utility model: a potential seat is fixedly connected to the back of the pipe fitting main body, and a power supply interface is fixedly inlaid on the back of the potential seat.

[0012] As a further solution of the present utility model: a controller is fixedly connected to the inner wall of the potential seat, and a status display lamp is fixedly connected to the back of the controller.

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

[0014] The pipe fitting with high anti-freezing performance can, through the controller, set the temperature range and alarm threshold inside the pipe core, then start the electric wire heating layer to heat the pipe fitting main body according to the preset requirements. At the same time, the temperature sensor is used to monitor the temperature inside the pipe core in real time. When the temperature drops to the preset threshold, the controller can automatically start the electric wire heating layer to heat the pipe core and the pipe fitting main body, which can prevent the liquid inside the pipe fitting from freezing, thereby avoiding leakage and damage caused by freezing cracks. It not only improves the reliability of the entire pipe fitting, but also extends its service life. When in use, through the provided middle heat preservation layer, anti-freezing layer and inner pressure-resistant layer, the pipe fitting main body has good cold resistance, ensuring that the pipe fitting can still maintain its structural integrity and normal function in a low-temperature environment.
