Description

Technical Field

[0001] The utility model relates to the technical field of pressure-stabilizing expansion water tanks, in particular to a fast-response pressure-stabilizing expansion water tank. Background Art

[0002] Water tanks are widely used in our daily life. Factories, mines, government offices, hospitals, schools and ordinary households all need boilers to supply hot water. Since the number of water supply points is determined according to usage, in the heating and water supply systems, fluctuations in system pressure may cause equipment damage or unstable water supply, making it difficult to determine the pressure of the water tank. Too high a water pressure wastes resources, and too low a water pressure does not flow out. The water tank pressure needs to be supplemented and adjusted.

[0003] A pressure-stabilizing expansion water tank is required during the operation of the heating and water supply system. During the use of the existing expansion water tank, when the internal pressure of the expansion water tank is too high or especially when the expansion water tank air tightness test is performed, the expansion water tank is prone to deformation or leakage due to the size of the expansion water tank and the different forces on each surface. The main reason is that the working pressure of the expansion water tank is small, the internal pressure bearing capacity is also small, and the air tightness test pressure is relatively high. In addition, the existing pressure-stabilizing expansion water tank has a slow response speed and limited adjustment ability, which cannot meet the needs of modern buildings for fast and stable pressure regulation and cannot meet the use requirements. Therefore, a fast-response pressure-stabilizing expansion water tank is proposed to solve the above problems. Utility Model Content

[0007] The buffer assembly includes an elastic telescopic rod fixedly mounted on the top of the water baffle and a reset spring fixed between the water baffle and the adjustment plate. One end of the elastic telescopic rod away from the water baffle is fixedly connected to the bottom of the adjustment plate.

[0008] Furthermore, the speed regulating motor is electrically connected to the controller, and a bearing adapted to the threaded rod is fixedly installed inside the sealing cover.

[0009] Furthermore, a limiting rod extending to the upper surface of the sealing cover is fixedly connected to the top of the adjustment plate, and the limiting rod is slidably connected to the inside of the sealing cover.

[0010] Furthermore, one end of the limiting rod away from the adjustment plate is fixedly connected to the limiting sleeve, and there are four limiting rods and four limiting sleeves. The four limiting rods are distributed in a rectangular shape on the upper surface of the adjustment plate.
