Description

Technical Field

[0001] The utility model relates to the technical field of three-way pipes, in particular to an antifreeze dredging type PVC three-way pipe fitting. Background Art

[0002] Tee fittings are a common connection fitting in pipeline systems, mainly used to change the flow direction of fluid in pipelines or to realize pipeline branching. Its design allows pipelines in three directions to be interconnected, hence the name "tee". Tee fittings play a vital role in building water supply and drainage, petrochemicals, natural gas transportation, heating and ventilation, and other industrial fluid transmission systems. Tee fittings are mainly divided into two basic types according to their shapes: T-shaped and L-shaped. T-shaped tee makes three pipes meet at one point, one of which is usually at a 90-degree angle to the other two pipes. It is suitable for situations where a fluid source needs to be divided into two directions of flow. L-shaped tee is used for the diversion or convergence of pipelines, one of which is connected to the main line, and the other two ports form an angle, which is often used to change the flow direction of fluid without diverting it.

[0003] However, the existing three-way pipe fittings have relatively single functions, and have limitations in dealing with the challenges of pipe blockage and extreme weather conditions, especially three-way pipe fittings made of PVC. Due to their high thermal expansion coefficient, the low temperature in winter can easily cause the material to become brittle. Not only is the internal water easy to freeze and cause blockage, but the frost heave force may also cause the pipe fittings to freeze and crack, which seriously affects the normal operation and service life of the pipeline system. Therefore, it is necessary to propose a new type of anti-freeze and unblocking PVC three-way pipe fitting. Utility Model Content

[0004] The purpose of the utility model is to solve the limitations of three-way pipe fittings in dealing with the challenges of blockage inside the pipe and extreme weather conditions, the low temperature in winter easily causes the material to become brittle, and the internal water easily freezes and causes blockage, and to propose an anti-freeze and unblocking PVC three-way pipe fitting.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an antifreeze and dredging type PVC three-way pipe fitting, including a pipe body, a working box is fastened to one side of the surface wall of the pipe body, a motor is installed on one side of the inner wall of the working box, the output end of the motor is fastened to the first rotating shaft, the first rotating shaft is fastened to the first dredging plate on the peripheral side of the surface wall, a waterproof box is installed on one side of the surface wall of the first rotating shaft, a worm is fastened to one side of the surface wall of the first rotating shaft, the surface wall of the worm is meshingly connected to two worm wheels, the inner wall sides of the two worm wheels are fastened to the second rotating shaft, the second rotating shaft is fastened to the second dredging plate on the peripheral side of the surface wall, and the second rotating shaft and the waterproof box are rotatably connected.

[0006] Preferably, a waterproof pad is installed on one side of the inner wall of the tube body, and a heating plate is installed on one side of the surface wall of the tube body.

[0007] Preferably, a telescopic rod is installed on one side of the surface wall of the working box, and a bracket is fastened to one side of the surface wall of the telescopic rod.

[0008] Preferably, a sliding rod is fixedly connected to one side of the inner wall of the bracket, and a forward and reverse threaded screw rod is rotatably connected to one side of the inner wall of the bracket.
