Description

Technical Field

[0001] The present invention relates to the technical field of water delivery equipment, and in particular to a device and method for controlling water flow stable pressure regulation. Background Art

[0002] Water pipelines are tubular systems used to transport water (including drinking water, industrial water, agricultural irrigation water, and recycled water). They are a core infrastructure for water resource allocation, supply, and transportation. Through a closed network of pipes, they transport water from sources such as reservoirs, rivers, groundwater, and sewage treatment plants to end users (urban residents, factories, and farmland). They offer high transportation efficiency, minimal losses, and minimal environmental impact.

[0003] In existing water pipelines, personnel mostly only control the water flow through water valves. That is, when the water flow is large, the water valve is used to control the water pipe to increase the diameter of the water pipe. When the water flow is small, the water valve can be closed to reduce the diameter of the water pipe, so as to ensure the stability of the water flow. However, the above method requires personnel to frequently open and close the water valve, and this closing method needs to rely on manual adjustment or automatic adjustment. Manual adjustment requires frequent operation by personnel, which is inconvenient. Automatic adjustment needs to rely on sensors for control. Although it is easy to use, it is inconvenient to troubleshoot when a fault occurs, resulting in low maintenance efficiency. Therefore, there are shortcomings.

[0004] In summary, it is necessary to invent a device and method for controlling water flow to stabilize pressure. Summary of the Invention

In this way, the water pressure can be stabilized through the auxiliary water pipe, and the device can be automatically adjusted according to the water pressure, which is more convenient for people to use.

[0030] Refer to the attached Figures 1-6 The present invention provides a water flow control and stable pressure regulating device, which includes a main water supply pipe 100 and an auxiliary water supply pipe 200. A filter screen 110 is provided on the inner wall of the main water supply pipe 100 and on one side close to the water inlet end. The inner wall side ends of the main water supply pipe 100 are provided with limit blocks 120 for limiting the installation of the filter screen 110.

The auxiliary water supply pipe 200 can provide auxiliary water supply when the water flow inside the main water supply pipe 100 is too large.

[0031] The auxiliary water inlet 300 is provided with a control mechanism for controlling the drainage of the auxiliary water supply pipe 200, and the top structure of the auxiliary water inlet 300 can be set as a detachable structure, which makes it convenient for personnel to disassemble the auxiliary water inlet 300 later so that they can remove the control structure for cleaning and replacement. The control structure includes an adjustment plate 310, which is slidably connected to the inner wall of the auxiliary water inlet 300, and the top of the outer wall of the adjustment plate 310 is rotatably connected to the adjustment screw 320.

The valve core 330 can be installed at the bottom end of the inner wall of the auxiliary water inlet 300 to bear the water pressure and also seal the bottom end of the auxiliary water inlet 300. The valve core 330 can be controlled to move up and down to allow the water flow to be auxiliary transported through the auxiliary water pipe 200. A partition plate 340 is provided above the top of the outer wall of the valve core 330. The top of the outer wall of the valve core 330 is fixed with a second tightening spring 341.

When the water flow is too large, the water flow will push the valve core 330 upward, so that the second holding spring 341 and the first holding spring 342 can shrink, so that the bottom end of the auxiliary water inlet 300 is exposed, allowing water to flow into the auxiliary water supply pipe 200.

[0032] A side damping water-passing plate 210 is fixed to the inner wall of the auxiliary water supply pipe 200 and one side close to the auxiliary water inlet 300 through a groove, and the outer wall of the side damping water-passing plate 210 can be fixed at a corresponding position on the inner wall of the auxiliary water supply pipe 200, and the two side damping water-passing plates 210 are rotatably connected to the main damping water-passing plate 220 on the opposite side, and annular grooves are provided on both sides of the outer wall of the main damping water-passing plate 220, and the outer wall side end of the side damping water-passing plate 210 can be fixed and slidably connected to the inner wall of the annular groove, and the main damping water-passing plate 220 can be rotatably connected to the side damping water-passing plate 210 when needed. The auxiliary water pipe 200 is provided with a water hole 230 on both sides of the outer wall of the side damping water-passing plate 210 and the main damping water-passing plate 220, and the water hole 230 is provided to allow water to flow through the side damping water-passing plate 210 and the main damping water-passing plate 220. The side damping water-passing plate 210 and the water hole 230 can buffer the rapidly passing water flow, so as to keep the water flow more stable. The outer wall side end of the main damping water-passing plate 220 is fixed with a worm gear ring 221, and the outer wall top of the auxiliary water pipe 200 and above the worm gear ring 221 is provided with a rotation groove. The worm 240 is rotatably connected to the inner wall of the worm 240 on both sides and located above the worm ring 221. The outer walls of the worm 240 are meshed with the outer wall of the worm ring 221. A bevel gear set 241 is provided on one side of the outer wall of the worm 240. A rotating rod 242 is fixed to the top of the outer wall of the upper bevel gear set 241. The top of the outer wall of the auxiliary water supply pipe 200 is rotatably connected to the outer wall of the rotating rod 242 through an opening. The person can turn the rotating rod 242 to make the bevel gear set 241 drive the worm 240 to rotate.

[0033] The use process of the present invention is as follows: a person skilled in the art can first assemble the device according to the above description, then connect all electrical devices to an external power supply, and control the operation of the device through an external controller. The control programs of all electrical devices are edited in advance by the production personnel before production. The present invention does not make any technical improvements here, but only assumes that it can be used normally to meet the needs of personnel;

[0034] First, according to the specified water pressure, the operator can control the adjustment plate 310 to move up and down by rotating the adjustment screw 320. This can control the compression state of the second abutting spring 341 and the first abutting spring 342 to increase the elastic force applied to the valve core 330. In this way, the valve core 330 can be controlled to what water pressure it will withstand before it moves upward. The specific value can be determined in advance through testing.

[0035] After completion, the personnel can fix the filter screen 110 on the water inlet end of the main water supply pipe 100, and the water to be transported can be transported through the main water supply pipe 100. When the water flow is large, the large water pressure will cause the valve core 330 to move upward, and the second tightening spring 341 and the first tightening spring 342 provided will contract, and the water flow will enter the auxiliary water inlet 300 and the auxiliary water supply pipe 200, so that the auxiliary water supply pipe 200 can assist in transporting the water and ensure the stability of the water flow. At the same time, if the water pressure is too high, the personnel can By rotating the rotating rod 242, the main damping water plate 220 is rotated to align the water hole 230, so that the side damping water plate 210 and the main damping water plate 220 can buffer the passing water to avoid excessive water pressure in the auxiliary water pipe 200. When the water flow decreases, the water pressure will be less than the elastic force of the second clamping spring 341 and the first clamping spring 342, and the valve core 330 will move downward to seal the auxiliary water inlet 300 pipe mouth, so that the water flow is only transported along the main water pipe 100.
