Description

Technical Field

[0001] The utility model relates to the field of water purification equipment, and particularly relates to a control main board of a purification equipment with compressive protection. Background Art

[0002] The control main board of the purification equipment is one of the main accessories of the purification equipment. When the purification equipment accesses and outputs water sources, it controls the input and output of the water sources, which can facilitate the control and use of the purification equipment and is an indispensable part when the purification equipment is in use;

[0003] However, the existing control main board of the purification equipment generally controls the entry and discharge of the water source. However, the water source can only be input and discharged singly, and the water pressure in the purification equipment cannot be controlled. The water pressure requirement in the purification equipment is crucial for its normal operation and water purification effect. If the water pressure is too low, it may lead to insufficient water output of the filter element, affecting the water purification effect. If the water pressure is too high, it may cause the filter element to be worn out excessively in a short time, shortening its service life;

[0004] Therefore, this case proposes a control main board of a purification equipment with compressive protection to solve the above technical problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a control main board of a purification equipment with compressive protection, which can effectively solve the technical problems in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A control main board of a purification device with compressive protection, comprising a main body mounting plate and a main controller. The main controller is fixedly installed at the front end of the main body mounting plate. A drain pipe is fixedly installed below the main controller at the front end of the main body mounting plate. One end of the drain pipe is fixedly installed with a drain valve pipe. A drain solenoid valve is embedded on the outer side of the drain valve pipe. A plurality of filter element outlet pipes are installed through the outer side of the drain pipe. A pressure relief valve pipe is fixedly installed on the outer side of the filter element outlet pipe. A pressure relief solenoid valve is embedded on the outer side of the pressure relief valve pipe. A first water pressure sensor is embedded on the outer side of the filter element outlet pipe on one side of the pressure relief valve pipe. An inlet pipe is fixedly installed on one side of the main body mounting plate. An inlet valve pipe is fixedly installed at the upper end of the inlet pipe. An inlet solenoid valve is embedded on one side of the inlet valve pipe. A plurality of filter element inlet pipes are installed through the outer side of the inlet valve pipe. A second pressure sensor and a booster solenoid valve are embedded on the outer side of the filter element inlet pipe, and the second pressure sensor is located on one side of the booster solenoid valve. A booster pump switch is fixedly installed on the front end of the main body mounting plate on one side of the drain pipe. A pressure discharge conveying pipe is connected between the booster pump switch and the pressure relief valve pipe. A booster conveying pipe is connected between the booster pump switch and the booster solenoid valve.

[0008] As a further solution of the present utility model, the pressure relief solenoid valve and the first water pressure sensor are both embedded inside the filter element outlet pipe. Each filter element outlet pipe and each filter element inlet pipe are inserted into the filter element as a group.

[0009] As a further solution of the present utility model, the drain valve pipe is connected to a direct lead water pipe, and the inlet valve pipe is connected to a tap water pipe.

[0010] As a further solution of the present utility model, the booster conveying pipe is connected to the inside of the filter element inlet pipe through the booster solenoid valve, and the pressure discharge conveying pipe is connected to the inside of the filter element outlet pipe through the pressure relief valve pipe.

[0011] As a further solution of the present utility model, the first water pressure sensor and the second pressure sensor are electrically connected to the signal input end of the main controller, and the drain solenoid valve, the pressure relief solenoid valve, the inlet solenoid valve, the booster solenoid valve and the booster pump switch are electrically connected to the signal output end of the main controller.

[0012] As a further solution of the present utility model, the main controller includes a central processing unit, a control module, an interaction module and an alarm module. The central processing unit is used for processing and calculating various data. The control module is used for controlling the operation of each solenoid valve. The interaction module is used for receiving manual control signals. The alarm module is used for receiving pressure alarm signals.

[0013] The first water pressure sensor and the second pressure sensor are connected to an alarm module. The alarm range of the alarm module is above 0.4 MPa detected by the first water pressure sensor and below 0.1 MPa detected by the second pressure sensor;

[0014] The inlet water solenoid valve, the booster solenoid valve, and the booster pump switch are connected to the main controller and the control module, and the opening control is realized by the control module.

[0015] The beneficial effects of the present utility model are as follows:

[0016] When the water pressure discharged from the filter element is too high, the first water pressure sensor detects the water pressure in the water outlet pipe of the filter element and sends a signal to the alarm module. When the water pressure exceeds 0.4 MPa (4 kgf / cm²) or more, the alarm module sends an instruction to the control module, causing the control module to control the pressure relief solenoid valve to open. Therefore, the pressure relief valve pipe discharges the pressure of the water outlet pipe of the filter element, reducing the pressure value in the water outlet pipe and the filter element, preventing excessive wear, and achieving stable drainage output;

[0017] When the pressure relief valve pipe discharges water, the discharged water enters the pressure discharge conveying pipe, and then is input into the booster pump switch through the pressure discharge conveying pipe, enabling the booster pump switch to store backup water source. The water source discharged by the pressure relief can be pressurized again, reducing the use loss and waste of the equipment.

[0018] When the water pressure discharged from the filter element is too low, the second pressure sensor detects the water pressure in the water inlet pipe of the filter element and sends a signal to the alarm module. When the water pressure is below 0.1 MPa (1 kgf / cm²) or less, the alarm module sends an instruction to the control module, causing the control module to control the booster pump switch and the booster solenoid valve to open. Therefore, the backup water source in the booster pump switch is conveyed to the water inlet pipe and the filter element of the filter element through the booster conveying pipe, increasing the water pressure in the filter element, preventing the pressure in the equipment from being too low, and enabling the filter element to operate normally for filtration.

One side of the main body mounting plate 1 is fixedly installed with a water inlet pipe 11. The upper end of the water inlet pipe 11 is fixedly installed with a water inlet valve pipe 12. A water inlet solenoid valve 13 is embedded on one side of the water inlet valve pipe 12. A plurality of filter element inlet pipes 14 are installed through the outer side of the water inlet valve pipe 12. A second pressure sensor 15 and a booster solenoid valve 16 are embedded on the outer side of the filter element inlet pipe 14, and the second pressure sensor 15 is located on one side of the booster solenoid valve 16. A booster pump switch 18 is fixedly installed on the front end of the main body mounting plate 1 on one side of the drain pipe 3. A pressure discharge conveying pipe 7 is connected between the booster pump switch 18 and the pressure relief valve pipe 8. A booster conveying pipe 17 is connected between the booster pump switch 18 and the booster solenoid valve 16.

[0024] In this embodiment, the pressure relief solenoid valve 9 and the first water pressure sensor 10 are both embedded inside the filter element outlet pipe 6. Each filter element outlet pipe 6 and each filter element inlet pipe 14 are inserted into the filter element as a group. The filter element outlet pipe 6 and the filter element inlet pipe 14 are used for installing inside the filter element to convey and drain water.

[0025] In this embodiment, the drain valve pipe 4 is connected to a direct lead water pipe, the water inlet valve pipe 12 is connected to a tap water pipe, the water inlet valve pipe 12 is the water inlet end, and the drain valve pipe 4 is the water outlet end.

[0026] In this embodiment, the booster conveying pipe 17 is connected to the inside of the filter element inlet pipe 14 through the booster solenoid valve 16, and the pressure discharge conveying pipe 7 is connected to the inside of the filter element outlet pipe 6 through the pressure relief valve pipe 8. The booster conveying pipe 17 has the effect of sending water into the filter element inlet pipe 14, and the pressure discharge conveying pipe 7 has the effect of draining water from the filter element outlet pipe 6.

[0027] In this embodiment, the first water pressure sensor 10 and the second pressure sensor 15 are electrically connected to the signal input end of the main controller 2, and the drain solenoid valve 5, the pressure relief solenoid valve 9, the water inlet solenoid valve 13, the booster solenoid valve 16 and the booster pump switch 18 are electrically connected to the signal output end of the main controller 2.

[0028] In this embodiment, the main controller 2 includes a central processing unit, a control module, an interaction module and an alarm module. The central processing unit is used to process and calculate various data. The control module is used to control the operation of each solenoid valve. The interaction module is used to receive manual control signals. The alarm module is used to receive pressure alarm signals;

[0029] The first water pressure sensor 10 and the second pressure sensor 15 are connected to the alarm module. The alarm range of the alarm module is above 0.4 MPa detected by the first water pressure sensor 10 and below 0.1 MPa detected by the second pressure sensor 15;

[0030] The water inlet solenoid valve 13, the booster solenoid valve 16 and the booster pump switch 18 are connected to the control module of the main controller 2, and the opening control is realized by the control module.

[0031] It should be noted that the present utility model is a main control board for controlling a purification device with compressive protection. When in use, the drain valve pipe 4 is connected to the direct water pipe, the water inlet valve pipe 12 is connected to the tap water pipe, and then the filter element outlet pipe 6 and the filter element inlet pipe 14 are inserted into the filter element as a group. The interaction module and the control module in the main controller 2 output control signals to the water inlet solenoid valve 13, so that tap water enters through the water inlet valve pipe 12. The tap water then enters the filter element through the inlet water pipe 11 and the filter element inlet pipe 14. Then, the interaction module and the control module in the main controller 2 output control signals to the drain solenoid valve 5, so that the drain valve pipe 4 is in an open state. The filtered tap water in the filter element is discharged from the drain valve pipe 4 through the filter element outlet pipe 6 and the discharge pipe 3 to control the input and output of the purification device;

[0032] When the water pressure in the filter element during drainage is too high, the first water pressure sensor 10 detects the water pressure in the filter element outlet pipe 6 and sends a signal to the alarm module. When the water pressure exceeds 0.4 MPa and above 4 kgf / cm2, the alarm module sends an instruction to the control module, so that the control module controls the pressure relief solenoid valve 9 to open. Therefore, the pressure relief valve pipe 8 discharges the pressure of the filter element outlet pipe 6, reducing the pressure value in the outlet pipe 6 and the filter element, and achieving stable drainage output;

[0033] When the pressure relief valve pipe 8 drains water, the drained water enters the pressure discharge conveying pipe 7, and then is input into the booster pump switch 18 through the pressure discharge conveying pipe 7, so that the booster pump switch 18 stores the standby water source to recycle the water source generated by the pressure relief.

[0034] When the water discharge pressure in the filter element is too low, the second pressure sensor 15 detects the water discharge pressure in the water inlet pipe 14 of the filter element and sends a signal to the alarm module. When the water pressure is lower than 0.1 MPa and 1 kgf / cm2, the alarm module sends an instruction to the control module, causing the control module to control the booster pump switch 18 and the booster solenoid valve 16 to open. Therefore, the reserved water source in the booster pump switch 18 is transported to the water inlet pipe 14 of the filter element and into the filter element through the booster delivery pipe 17, increasing the water pressure in the filter element and enabling the filter element to filter the tooling normally.
