Description

Technical Field

[0001] The utility model relates to the technical field of cold-rolled stainless steel, in particular to a high-pressure stable water supply system for cold-rolled stainless steel. Background Art

[0002] At present, stainless steel needs to be pickled during cold rolling. After pickling, the stainless steel needs to be rinsed with water to remove the acid and impurities on the surface of the steel plate to ensure the surface is clean. If the temperature of the stainless steel rises during the cold rolling process, it also needs to be cooled with water. Therefore, high-pressure water is required for cold rolling of stainless steel.

[0003] In the related technology, the commonly used high-pressure water supply system consists of a water pump, a water tank, a water pressure switch, etc. The water pump supplies water to the water tank to a certain pressure, and the water pressure switch controls the water pump to shut down. When water is used, the water tank pressure decreases, and the water pressure switch controls the water pump to start replenishing water and pressurizing.

[0004] When such a commonly used high-pressure water supply system is supplying water, the water pressure switch controls the opening and closing of the water pump according to the pressure changes in the water tank. Therefore, when the water pump is turned on, the water pressure may suddenly increase. When water is used, the water tank pressure decreases, the water output also decreases, the water output pressure is unstable, and it is difficult to adjust the water output pressure according to demand. Utility Model Content

[0005] The utility model aims to provide a high-pressure stable water supply system for cold-rolled stainless steel to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a high-pressure stable water supply system for cold-rolled stainless steel, comprising a water tank and a water pump, the water tank is connected to a drain pipe, the water pump is connected to the water tank and the drain pipe, a constant flow valve is installed on the drain pipe, the water tank can store high-pressure water, and provide high-pressure water for cold-rolled stainless steel, and the constant flow valve can control the stability of the water outlet pressure to avoid the influence of water pressure changes on the stability of the water outlet;

[0007] The upper surface of the water tank is connected to an air filling tube, and the other end of the air filling tube is connected to an air pump, through which the water can be pressurized, and the water pressure can be adjusted according to demand to increase the water outlet pressure. A water level gauge and a barometer are installed on the upper surface of the water tank;

[0008] The water pump, air pump, water level gauge and barometer are electrically connected to a controller, and the controller is used to achieve pressure stabilization and water replenishment of the water tank, so that water can be supplied continuously.

[0009] Furthermore, the water inlet and outlet ends of the water pump are respectively equipped with valves and one-way valves. A connecting pipe is provided on the lower surface of the water tank, and a valve is also installed on the connecting pipe. The connecting pipe is connected to the water pump and the drain pipe, and a one-way valve is also installed on the drain pipe. A one-way valve is also installed on the inflation pipe to ensure that the pressure in the water tank is stable and that the water in the water tank only flows toward the sprinkler head, so that the water path can be better controlled.

[0010] Furthermore, a pressure relief valve is installed on the upper surface of the water tank. When the air pressure in the water tank is too high, air is discharged through the pressure relief valve, which can reduce the pressure in the water tank and prevent the water tank from being damaged.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The water pump and air pump supply water and inflate the water tank, which can adjust the pressure in the water tank, making it easier to change the water outlet pressure according to demand. The constant flow valve can maintain a stable water outlet pressure. When the water pressure discharged from the water tank changes, it will not affect the water spraying pressure of the sprinkler head, and the water supply pressure is more stable.

[0013] (2) The water level meter detects the water level in the water tank. When the water level drops to the set threshold, the controller controls the water pump to replenish water to the water tank. At the same time, the water pump can also supply water to the sprinkler head. When the water tank leaks, it can also supply water to the sprinkler head, which has a better fault tolerance rate.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example:

[0018] See also Figure 1The utility model provides a technical solution: a high-pressure stable water supply system for cold-rolled stainless steel, comprising a water tank 1 and a water pump 7, wherein the water tank 1 is connected to a drain pipe 6, wherein the water pump 7 is connected to the water tank 1 and the drain pipe 6, wherein a constant flow valve 13 is installed on the drain pipe 6, wherein the constant flow valve 13 mainly realizes constant flow control for the drainage of the water tank 1, thereby ensuring that the water pressure does not fluctuate during drainage, and the formula for cold-rolled stainless steel is stable;

[0019] The upper surface of the water tank 1 is connected to an air filling pipe 2, and the other end of the air filling pipe 2 is connected to an air pump 3. A water level gauge 9 and a barometer 10 are installed on the upper surface of the water tank 1. The barometer 10 detects the pressure of the water tank 1. When the pressure of the water tank 1 is less than a preset value, the air pump 3 can inflate and pressurize the water tank 1 in time.

[0020] The water pump 7, air pump 3, water level gauge 9 and barometer 10 are electrically connected to the controller 4. The controller 4 controls the operation of the water pump 7 and the air pump 3 according to the detection results of the water level gauge 9 and the barometer 10, so as to realize automatic water replenishment and pressure stabilization of the water tank 1 without manual control.

[0021] In this embodiment, if Figure 1 As shown, the water inlet and outlet ends of the water pump 7 are respectively installed with a valve 8 and a one-way valve 5. When the water pump 7 needs to be repaired, just close the valve 8. The multiple water pumps 7 work independently of each other and will not affect the normal water replenishment of the water tank 1.

[0022] In this embodiment, if Figure 1 As shown, a connecting pipe 11 is provided on the lower surface of the water tank 1, and a valve 8 is also installed on the connecting pipe 11. The connecting pipe 11 is connected to the water pump 7 and the drain pipe 6. A one-way valve 5 is also installed on the drain pipe 6. When the water tank 1 needs to be cleaned or repaired, the valve 8 is closed and the water pump 7 can directly supply water to the spray head 14 without affecting the use of water.

[0023] In this embodiment, if Figure 1 As shown, a one-way valve 5 is also installed on the inflation tube 2 to prevent the gas in the water tank 1 from flowing back into the air pump 3, thereby protecting the air pump 3.

[0024] In this embodiment, if Figure 1 As shown, a pressure relief valve 15 is installed on the upper surface of the water tank 1. When the threshold value of the pressure of the water tank 1 is greater than the pressure relief valve 15, the pressure relief valve 15 opens to reduce the pressure of the water tank 1 to prevent the water tank 1 from being over-pressurized.

[0025] In this embodiment, if Figure 1 As shown, a spray head 14 and an electric valve 12 are also installed on the drain pipe 6. The electric valve 12 can automatically control the water spraying of the spray head 14, and the spray head 14 delivers water to a designated location.

[0026] Specifically, when in use, the water inlet of the water pump 7 is connected to the water source, the water pump 7 pumps water and sends the water to the water tank 1, so that the pressure in the water tank 1 increases, and the water level gauge 9 monitors the water level of the water tank 1. After the water level reaches the standard, the controller 4 turns off the water pump 7 based on the signal of the water level gauge 9. If the barometer 10 detects that the pressure in the water tank 1 is insufficient, the controller 4 controls the air pump 3 to increase the pressure of the water tank 1. When the electric valve 12 is opened, the water in the water tank 1 is sprayed out by the spray head 14 through the drain pipe 6 and the constant flow valve 13. The constant flow valve 13 can keep the water outlet pressure stable, ensuring that the water pressure of the water sprayed from the spray head 14 will not fluctuate, thereby achieving stable high-pressure water supply.
