Description

Technical Field

[0001] The invention relates to the technical field of pressure relief devices, in particular to a water supply pipeline pressure relief device. Background Art

[0002] The valve is a control component in the fluid conveying system, which has the functions of shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. The valves used in fluid control systems are of various types and specifications, from the simplest shut-off valve to the various valves used in extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard custom valves, etc. according to the material. When the water flow inside the pipeline is fast, the impact of the water flow is too large, and the sudden large amount of water flow may cause the water valve to burst, etc., which will seriously affect the residents' domestic water use. Based on the above possible situations, a valve that can effectively prevent the water valve from bursting under the action of water pressure is needed.

[0003] When performing pressure relief operations, the existing technologies mostly achieve pressure relief by directly releasing the domestic water in the pipes, but this will result in a large amount of water resource waste. Therefore, when the pressure requirement is not exceeded by much, the water in the pipes can be diverted to reduce the water volume in the pipes at the same time. After adjusting the water pressure at the source, the diverted water can be reintegrated to save water resources. Summary of the invention

[0004] The purpose of the present invention is to provide a water supply pipeline pressure relief device to solve the problems raised in the background technology.

[0005] An embodiment of the present application provides a water supply pipe pressure relief device, including a connecting pipe, a first pressure relief tank is fixedly installed on the connecting pipe, a first motor is fixedly installed on the first pressure relief tank, a flange is fixedly installed on the connecting pipe, an installation box is provided on the connecting pipe, a pressure gauge is provided on the installation box, a second pressure relief tank is fixedly installed on the connecting pipe, and a pipeline is provided between the first pressure relief tank and the second pressure relief tank.

[0006] By adopting the above technical scheme, the device is installed on the water supply pipe. When the water pressure in the water supply pipe is relatively large, the water pressure in the connecting pipe will increase. When the water pressure in the connecting pipe is relatively large, the water baffle in the first pressure relief box will be squeezed to move. When the water baffle moves to the top of the water outlet, water can enter the pipe through the water outlet. When water enters the second pressure relief box through the pipe and the water inlet, it will squeeze the blocking ball. When the amount of water in the second pressure relief box is large enough to squeeze the blocking ball downward, the second spring will contract, so that the blocking ball will move out of the circular groove, and water can flow into the connecting pipe again through the circular groove and the water outlet groove. When connecting to different water supply pipes, personnel can make adjustments according to the maximum water pressure value that the water supply pipe to be processed can withstand. Starting the first motor can drive the threaded rod to rotate. When the threaded rod rotates, it will drive the sleeve to move, thereby driving the moving block to move, thereby squeezing the first spring. When the first spring is squeezed, its impact on the bottom will increase. The pressure of the movable plate can be adjusted to adjust the pressure that the pressure relief box can release. At the same time, when the amount of water in the pipeline is large, it will drive the blades to rotate, thereby driving the first rotating wheel to rotate, thereby driving the first belt to rotate, thereby driving the second rotating wheel to rotate. When the second rotating wheel rotates, it will drive the rotating block to rotate, thereby driving the mechanism in the placement box to rotate, so that self-generation can be performed. The electricity generated by self-generation can be used for structures such as the PLC control board. A speed test sensor is provided on the first rotating wheel. When the sensor sends a large signal, it means that the water pressure in the pipeline is also large. At this time, the PLC control board can open the electric baffle on the second pressure relief box to release the internal pressure. After the above operation, when the pressure in the connecting pipe is large, it can be diverted, and the diverted water can be re-entered into the connecting pipe at the rear, saving water resources and providing a certain warning time. If the source of the connecting pipe is not processed in time, when the pressure in the pipeline also increases, the final water discharge and pressure relief operation will be performed on it.

[0012] By adopting the above technical solution, when the threaded rod rotates, it will drive the sleeve to move, thereby driving the moving block to move, thereby squeezing the first spring. When the first spring is squeezed, it will increase its pressure on the moving plate below, thereby adjusting the pressure that can be relieved by the pressure relief box.

[0013] Optionally, a connecting block is fixedly installed at the lower end of the movable plate, a water baffle is fixedly installed at the lower end of the connecting block, a water outlet is opened on the side wall of the first pressure relief box, and a pipe is arranged on the water outlet.

[0014] By adopting the above technical solution, when the water pressure in the connecting pipe is high, the water baffle in the first pressure relief box will be squeezed to move. When the water baffle moves to above the water outlet, water can enter the pipeline through the water outlet.

[0016] By adopting the above technical solution, when water enters the second pressure relief tank through the pipe and the water inlet, it will squeeze the blocking ball. When the amount of water in the second pressure relief tank is large enough to squeeze the blocking ball downward, the second spring can contract, thereby moving the blocking ball out of the circular groove, and the water can flow into the connecting pipe again through the circular groove and the water outlet groove.

The electricity generated by self-generation can be used for structures such as the PLC control board. A speed test sensor is provided on the first rotating wheel. When the sensor transmits a large signal, it means that the water pressure in the pipeline is also large.

[0031] By adopting the above technical solution, the device is installed on the water supply pipeline. When the water pressure in the water supply pipeline is large, the water pressure in the connecting pipe 1 will increase. When the water pressure in the connecting pipe 1 is large, the water baffle 12 in the first pressure relief box 3 will be squeezed to move. When the water baffle 12 moves to above the water outlet 13, water can enter the pipeline 5 through the water outlet 13.

When the second rotating wheel 23 rotates, it will drive the rotating block 25 to rotate, thereby driving the mechanism in the placement box 26 to rotate, so that self-generation can be performed.
