Problems solved by technology

Once the pressure of municipal water supply cuts off or becomes zero, it will not only have an immediate impact on residents' water use, but also cause damage or burnt water supply equipment and water pumps due to negative pressure due to insufficient water supply.

Embodiment 1

[0010] see figure 1 , an automatic water replenishment device provided by the present invention is connected and arranged on any outlet pipe of the water inlet pipe 1, and includes a water storage tank 2, a one-way valve 3, a water replenishment pipe 4 and a liquid level float 5, and the one-way valve 3 It is fixed at the outlet end of the water inlet pipe 1. The check valve 3 is provided with a valve core 6, which is automatically adjusted according to the water flow in the water inlet pipe 1. When the municipal water supply pressure is normal, the valve core 6 is closed. The water flow is directly discharged from the water outlet pipe 7 connected with the water inlet pipe 1, thereby realizing continuous and normal water supply.

[0011] When the municipal water supply pressure decreases or the water is cut off, the valve core 6 opens, and the water in the water storage tank 2 passes through the rubber soft seal 8 connected to it, and enters the outlet pipe 7 through the one-...

Abstract

The invention discloses an automatic water replenishing device which comprises a water storage tank, a one-way valve, a water replenishing pipe disposed at a water inlet of the water storage tank and liquid level floater. The device is connected to an optional water outlet of a water inlet pipe. The liquid level floater is connected to the water replenishing pipe. The other end of the water replenishing pipe is connected with the water inlet pipe. The one-way valve is fixed to the exit of the water inlet pipe. A valve core which can automatically open when water pressure decreases is disposed inside the one-way valve. The automatic water replenishing device is simple in structure and convenient to manufacture. When municipal water supply pressure decreases or the water supply is cut off, water in the water tank can be replenished into the water inlet pipe through the water replenishing pipe, and accordingly continuous water supply is achieved, and water supply pressure is stabilized.

Description

technical field [0001] The invention relates to a water supply device, in particular to an automatic water replenishing device. Background technique [0002] During municipal water supply, it is usually necessary to use water supply equipment to pressurize the water before it can enter the place of use. Once the pressure of municipal water supply cuts off or becomes zero, it will not only have an immediate impact on residents' water use, but also cause damage or burnout of water supply equipment and water pumps due to negative pressure due to insufficient water supply. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an automatic water supply device. The present invention has a simple structure and can ensure continuous and stable water supply when the municipal water supply is insufficient. [0004] The object of the present invention is achieved through the following tec...
