Description

Technical Field

[0001] The utility model relates to the technical field of non-negative pressure water supply equipment, in particular to a high-efficiency energy-saving pressure stabilizing device in non-negative pressure water supply equipment. Background Art

[0002] Non-negative pressure water supply equipment is a new type of water supply device that connects directly to the municipal water supply network. During operation, the device senses the pressure of the municipal water supply network through a pressure sensor. When the municipal water supply network pressure meets user needs, the device directly uses the municipal water supply network pressure to supply water. During this time, the device's water pump operates at a low speed or stops, thus achieving energy conservation. When the municipal water supply network pressure is insufficient, the device's water pump starts to operate. The device uses components such as a flow stabilization tank to buffer and regulate the municipal water supply to prevent negative pressure from affecting the municipal water supply network. At the same time, the water pump pressurizes the water before supplying it to the user, ensuring stable water pressure and volume.

[0003] In non-negative pressure water supply equipment, a pressure stabilizing device is required. Chinese utility model patent publication number CN208395916U discloses a non-negative pressure energy-saving water supply equipment for high-rise buildings. The equipment comprises a base plate, a mounting plate, and a non-negative pressure energy-saving water supply equipment body fixedly connected to the upper end of the mounting plate. The non-negative pressure energy-saving water supply equipment body comprises a flow stabilizing compensator, an intelligent frequency conversion control box, and a water pump. The flow stabilizing compensator is provided with an inlet pipe, the water inlet end of the water pump is connected to the flow stabilizing compensator, the water outlet end of the water pump is connected to an outlet pipe, the outlet pipe is connected to an air pressure tank, and the outlet pipe is provided with a check valve. The upper end of the base plate is provided with a mounting groove, and the mounting plate is located within the mounting groove. This utility model has an excellent shock absorption effect, reducing the vibration of the non-negative pressure energy-saving water supply equipment, thereby effectively protecting the equipment, and has good heat dissipation and ventilation effects, maintaining a normal operating temperature of the equipment.

[0004] However, during the use of this utility model, since the interior of the flow stabilizer compensator is usually used as a temporary water storage tank, the tap water entering the flow stabilizer compensator will more or less contain certain impurities, and these impurities may adhere to the inner wall of the flow stabilizer compensator, affecting the water quality of the tap water and failing to meet production needs. Therefore, a high-efficiency and energy-saving pressure-stabilizing device in a non-negative pressure water supply equipment is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a high-efficiency and energy-saving pressure-stabilizing device in a non-negative pressure water supply equipment, which has the advantage of facilitating the filtering of the tap water inside the flow stabilizer compensator. It solves the problem that the tap water entering the flow stabilizer compensator, which is usually used as a temporary water storage tank, will more or less contain certain impurities, and these impurities may adhere to the inner wall of the flow stabilizer compensator, affecting the water quality of the tap water and failing to meet production needs.

[0008] Furthermore, the filter hole diameter of the outer filter cartridge is smaller than the filter hole diameter of the inner filter cartridge, and the end of the water inlet pipe away from the flow stabilizing compensator is connected to the municipal pipe network.

[0009] Furthermore, a pressure gauge is fixedly installed on the top of the steady flow compensator, and a negative pressure suppressor is fixedly installed on the front of the top of the steady flow compensator.

[0010] Furthermore, a sewage pipe is fixedly connected to a side of the flow stabilizing compensator close to the water outlet pipe, and a support frame is fixedly connected between the flow stabilizing compensator and the mounting base.

The high-efficiency and energy-saving pressure-stabilizing device in the non-negative pressure water supply equipment, by providing an outer filter cartridge and an inner filter cartridge, can enable the water inlet pipe to directly transport tap water to the inner filter cartridge, thereby being able to perform secondary filtration on the tap water. By providing a sealing cover, it is convenient for the staff to remove the outer filter cartridge for cleaning. On the other hand, it will not affect the internal pressure of the flow stabilizing compensator during operation, thereby achieving the effect of filtering the tap water and improving the quality of the tap water.

[0016] 2. The high-efficiency and energy-saving pressure-stabilizing device in the non-negative pressure water supply equipment can adjust the water pressure inside the water outlet main by setting a pressure-stabilizing tank and a connecting pipe, so as to achieve a stable pressure inside the water outlet main, thereby achieving the effect of high-efficiency, energy-saving and pressure stabilization.
