Description

Technical Field

[0001] This utility model relates to the field of water supply in water conservancy or municipal engineering, specifically a pressure regulating device with two pump stations in parallel. Background Technology

[0002] Municipal water supply refers to the provision of safe and hygienic drinking water to urban residents by government agencies or relevant departments. It is a crucial component of modern urban infrastructure and plays a vital role in maintaining the quality of life for urban residents and ensuring the healthy development of the city.

[0003] Currently, due to the different design flow rates and heads of the two pumping stations, as well as the different diameters and lengths of the water supply pipes at the junction of the two pumping stations, the water head at the junction of the two pumping stations is different. This can lead to water blockage in one of the pumping stations, increasing the energy consumption of the pumping station. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a pressure regulating device for parallel dual pump stations. A pressure regulating facility is installed before the water collection point of each of the dual pump stations. The pressure is identified by a pressure gauge in the water supply pipes of the dual pump stations, and the pressure before the water collection point is automatically adjusted so that both pump stations are at their highest efficiency, thus saving energy consumption of the pump stations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-pump station parallel pressure regulating device, comprising a parallel pressure regulating unit, a confluence pipe connected below the parallel pressure regulating unit, a pipe rack installed at one end of the confluence pipe, and a support frame installed at the other end of the confluence pipe; the parallel pressure regulating unit contains a plurality of pressure regulators, and a plurality of parallel frames are connected between the plurality of pressure regulators; a plurality of locking lugs are fixed to the outer wall of the parallel frames, and locking bolts are connected to each locking lug; a top support block is fixed below one of the parallel frames. The parallel frames are mainly used to fix two pressure regulators, placing them at opposite ends of the parallel frames, with one pressure regulator connected to an external reservoir water flow pipe and the other pressure regulator connected to an external forebay water flow pipe.

[0006] Furthermore, the pressure regulator is equipped with an adjusting pressure wheel, on which an inlet pipe and an outlet pipe are mounted. A pressure sensing rod extends through the side wall of the adjusting pressure wheel, and an electrically controlled sensing push rod is connected to the top of the pressure sensing rod. An external fixing bracket is fixed to the outer wall of the adjusting pressure wheel. After the inlet pipes are connected, they work in conjunction with the adjusting pressure wheel to adjust the pressure, ensuring that the outlet pressures of the two pressure regulators are the same, thus preventing water blockage at the water collection point.

[0007] Furthermore, the electrically controlled induction push rod is embedded inside the external fixing frame, the water inlet pipe is used to connect to an external reservoir or forebay, the water outlet pipe is connected to the confluence conduit, and the locking bolt is connected to the surface of the adjusting pressure wheel. The locking bolt is mainly used to penetrate the locking bolt lug and connect to the outer wall of the adjusting pressure wheel, thereby firmly fixing the pressure adjusting wheel to both ends of the parallel frame.

[0008] Furthermore, both ends of the parallel frame are connected to the pressure regulator, and the bottom of the top support block is fixed to the outer wall of the confluence pipe. The adjusting pressure wheel mainly works with the pressure sensing rod to regulate the water flow pressure. The top support block mainly supports the pressure regulator, allowing it to be mounted above the confluence pipe. Together with the pipe frame on the confluence pipe, it completes the connection of the water supply pipe, which then merges into the confluence pipe after pressure regulation.

[0009] Furthermore, the pressure sensing rod is equipped with a sensor to work in conjunction with the electrically controlled induction push rod to achieve pressure regulation. The sensor on the pressure sensing rod mainly performs pressure measurement, thereby triggering and adjusting the electrically controlled induction push rod based on the setting or pressure change, allowing the pressure regulators connected to two different pipes to achieve pressure equalization. Beneficial effects

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention installs a parallel pressure regulating device on the confluence pipe after the two pump stations, sets a pressure regulator before each water collection point, and uses a sensor on the pressure sensing rod to measure the pressure and identify the pressure of the water supply pipe of the two pump stations. This triggers an electronically controlled induction push rod to automatically adjust the pressure before the water collection point, thus preventing water blockage at one of the pump stations and indirectly ensuring that both pump stations are at their highest efficiency, thereby saving pump station energy consumption.

[0020] The working principle of this utility model is explained below:

[0021] This utility model involves placing the confluence pipe 1, pipe rack 2, and support frame 3 at a designated position, and installing a parallel pressure regulating device 4 above it. The parallel frame 42, with locking lugs 43 and locking bolts 44, fixes pressure regulators 41 to both ends of the parallel frame 42. One pressure regulator 41 is connected to the reservoir's pipeline, and after pressurization at pump station A, water is supplied to the inlet pipe 412 of one pressure regulator 41. The other pressure regulator 41 is connected to the forebay's pipeline, and after pressurization at pump station B, water is supplied to the inlet pipe 412 of the other pressure regulator 41. The two... The different water pressures after pressurization impact the pressure sensing rod 414, causing it to flow from the outlet pipe 413 into the confluence pipe 1. To prevent water blockage at the confluence point, the electrically controlled induction push rod 416 on the external mounting bracket 415, in conjunction with the sensor on the pressure sensing rod 414, completes pressure sensing, thereby triggering the electrically controlled induction push rod 416 to push inward or retract outward, so that the water pressure at the confluence point of the two pressure regulators connected to different water supplies is the same, preventing water blockage in one pump station, and indirectly ensuring that both pump stations are at their highest efficiency, thus saving pump station energy consumption.
