Description

Technical Field

[0001] This utility model relates to the field of fire pump technology, and in particular to a fire pump pressure stabilizing device. Background Technology

[0002] Firefighting pump pressure stabilization devices play a crucial role in ensuring fire safety. They mainly consist of a pressure stabilizing pump, a pressure tank, and a control box. The pressure stabilizing pump acts as a tireless guardian, continuously operating to ensure stable water pressure within the pipeline network and promptly replenishing pressure lost due to leaks. The pressure tank stores energy during low-water-use periods and releases it during peak periods, working in conjunction with the pressure stabilizing pump to maintain water pressure balance and prevent significant pressure fluctuations. This pressure stabilization device features an intelligent control system that monitors pipeline water pressure in real time using high-precision pressure sensors. If the water pressure deviates from the set range, the control box quickly issues commands to precisely regulate the start and stop of the pressure stabilizing pump. This not only greatly improves work efficiency but also reduces energy waste, ensuring firefighting water is always on standby and providing a solid support for fire suppression, effectively protecting the safety of buildings and people's lives and property.

[0003] A search revealed Chinese Patent Publication No. CN209244794U, which discloses a pressure stabilizing device for a fire-fighting engineering water pump, relating to the field of fire-fighting equipment technology. The device includes a pressure stabilizing tank and a water tank. A rubber diaphragm is fixedly installed inside the pressure stabilizing tank. An air chamber is formed between the inner wall of the pressure stabilizing tank and the rubber diaphragm. A water chamber is formed between the inner walls of the rubber diaphragm and the inner wall of the pressure stabilizing tank. A pressure sensor is fixedly installed on the right side of the pressure stabilizing tank and connected to the air chamber. An air inlet pipe is fixedly installed on the right side of the right side of the upper surface of the pressure stabilizing tank. An exhaust pipe is fixedly installed on the middle of the upper surface of the pressure stabilizing tank. This invention stabilizes the water pressure pumped by the water pump through a pressure stabilizing tank, resulting in a more stable water output from the fire hydrant and better fire extinguishing effect. Simultaneously, a second electric regulating valve adjusts the water output of the second water pump, making its operation more stable and ensuring its normal use, while also extending its service life. However, while this device achieves the goal of adjusting the water output of the second water pump and ensuring its stable operation, it cannot solve the problem of unstable water pressure during use, which leads to poor fire extinguishing effect.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, water flows into the pressure stabilizing tank through the inlet valve and then flows out through the outlet valve. When the pressure inside the pressure stabilizing tank increases, the piston column will rise, compressing the spring. At the same time, gas flows up through the circular hole on the piston column, and the pressure regulating valve is opened, allowing the gas to be discharged until the gas pressure inside the pressure stabilizing tank stabilizes. When the pressure is too low, the pressure regulating valve closes, maintaining a stable gas pressure inside the pressure stabilizing tank. This ensures that the gas pressure inside the pressure stabilizing tank is continuously kept stable, preventing it from being too high or too low and thus affecting the performance of the product.

[0031] 2. In this utility model, pressing the pressure regulating valve will cause the orifice cylinder to slide downwards, and the crossbar will move upwards relative to the irregular hole. When the pressure regulating valve is rotated, the pressure regulating valve will cause the orifice cylinder to rotate, and the crossbar will move to the other end of the irregular hole. At this time, the pressure regulating valve can be removed and a new valve can be installed, thus achieving the effect of replacing the pressure regulating valve. Attached Figure Description
