Description

Technical Field

[0001] This utility model relates to a water replenishment device, specifically a pressure-stabilizing automatic water replenishment device. Background Technology

[0002] Water replenishment systems, as a commonly used industrial water treatment system, have attracted much attention from industry professionals. Currently, most water replenishment systems on the market are manual. Staff manually replenish water according to the situation. This not only consumes a large amount of manpower, but also, because the timing of water replenishment is mostly based on the operator's experience, it is prone to errors, easily missing the optimal replenishment time, and sometimes even causing danger, resulting in a short equipment lifespan. Summary of the Invention

[0003] Purpose of the invention: The purpose of this utility model is to overcome the shortcomings of the prior art and provide a soft water pressure stabilizing automatic water replenishment device that ensures stable water pressure, smooth and reliable operation, and long service life in a closed-loop circulating water system.

[0004] Technical Solution: To solve the above-mentioned technical problems, the soft water pressure stabilizing automatic water replenishment device of this utility model includes a pressure stabilizing tank and a pump valve unit. The pump valve unit includes a mounting frame, on which two water replenishment pumps are mounted. A water inlet pipe is provided at the front end of the water replenishment pumps, and the rear end of the water replenishment pumps is connected to the pressure stabilizing tank through a connecting main pipe. A water supply valve is provided on the connecting main pipe. An air source box is provided on the mounting frame next to the water replenishment pumps. The air source box is connected to the pressure stabilizing tank through an air inlet pipe and a connecting pipe. The pressure stabilizing tank is connected to an air outlet pipe through a connecting pipe. A pressure reducing valve is provided on the air inlet pipe, and a pressure stabilizing valve is provided on the air outlet pipe. A drain pipe is provided on the mounting frame and is connected to the pressure stabilizing tank.

[0005] Furthermore, the water supply pump is divided into water supply pump I and water supply pump II. A butterfly valve III is provided on one side of water supply pump I and a check valve I is provided on the other side. A butterfly valve IV is provided on one side of water supply pump II and a check valve II is provided on the other side.

[0006] Furthermore, the water supply valve is a pneumatic water supply valve, with butterfly valve I on one side and butterfly valve II on the other side.

[0007] Furthermore, an electric ball valve is provided on the sewage pipe, and a butterfly valve V is provided on one side of the electric ball valve and a butterfly valve VI is provided on the other side.

[0008] Furthermore, the pressure reducing valve is a pneumatic regulating valve I, with a ball valve I on one side and a ball valve II on the other side. A pressure transmitter I is provided on one side of the ball valve I, and a gas safety valve is provided on one side of the ball valve II. A branch pipe I is provided below the air inlet pipe, and a ball valve III is provided on the branch pipe I.

[0009] Furthermore, the pressure regulating valve is a pneumatic regulating valve II, with a ball valve IV on one side and a ball valve V on the other side. A pressure transmitter II is provided on one side of the ball valve IV, a branch pipe II is provided below the outlet pipe, and a ball valve VI is provided on the branch pipe II.

[0010] Beneficial Effects: Compared with the prior art, the significant advantages of this utility model are: the overall structure of this utility model is reasonably designed, including a pressure stabilizing tank and a pump and valve unit. The pump and valve unit includes an integrated installation of pumps and valves, with a compact structure. The water replenishment pump adopts a one-in-one standby configuration. When water replenishment is needed, the water replenishment pump will determine whether to start or stop the pump based on the liquid level in the water replenishment tank. During the pump start-up process, if the pump at the working position fails, the standby pump will be started. When the water replenishment pump is in working condition, the water supply valve is closed. When the set liquid level is reached, the water replenishment pump stops working, and the water supply valve opens, connecting the pressure stabilizing tank and the soft water closed-loop system. The nitrogen inlet valve (pressure reducing valve) and nitrogen vent valve (pressure stabilizing valve) automatically operate according to the pressure of the pressure stabilizing tank to achieve constant pressure control of the pressure stabilizing tank. When the nitrogen pressure in the pressure stabilizing tank is greater than or less than the set value (liquid level rises or falls, leakage), the pressure stabilizing part will replenish gas to regulate and maintain a constant gas pressure in the tank. This device can ensure stable water pressure in the closed-loop circulating water system, smooth and reliable operation, and long service life. Attached Figure Description

This device can ensure stable water pressure in the closed-loop circulating water system, operate smoothly and reliably, and has a long service life.
