It is a pump that is immersed in a groundwater well for pumping and transporting water, and is widely used in farmland irrigation and drainage, industrial and mining enterprises, urban water supply and drainage, and sewage treatment, etc. Since the motor is submerged in water at the same time, the structural requirements for the motor are special compared with general motors. The structural forms of its motors are divided into 4 types: dry type, semi-dry type, oil-filled type, and wet type.

[0003] The integrated valve for deep well pumps in the prior art cannot regulate the pressure in the connected pipe. A large pressure will affect the flow of liquid and the stability of the pipeline, and the pressure in the integrated valve will indirectly affect the operating stability of the deep well pump. Therefore, those skilled in the art have provided a multi-functional integrated valve for deep well pumps to solve the problems raised in the above background art. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a multi-functional integrated valve for deep well pumps to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A multi-functional integrated valve for deep well pumps, including a valve body. Both sides of the valve body are communicated with connecting pipes. The top of the valve body is hermetically and rotationally connected with a valve rod. The bottom end of the valve rod extends into the valve body and is fixedly connected with a sealing ball. Two grooves are symmetrically formed on the outer wall of the sealing ball. A vent hole is formed through the top of one of the connecting pipes. A plurality of first tension springs are annularly arranged on the bottom inner wall of the vent hole, and the tops of the plurality of first tension springs are fixedly connected with the same sealing cover. The bottom of the sealing cover is hermetically attached to the top of the vent hole. A plurality of heat conduction pipes are annularly and fixedly connected to the outer wall of the other connecting pipe, and the same heater is fixedly embedded on the plurality of heat conduction pipes.

[0006] As a further solution of the utility model: A second filter cartridge and a first filter cartridge are respectively inserted through the two connecting pipes. Connecting rings are fixedly connected to the inner walls of the second filter cartridge and the first filter cartridge. A plurality of second tension springs are annularly arranged on one side of the two connecting rings facing the same direction. The ends of the plurality of second tension springs on both sides away from the connecting rings are respectively fixedly connected with a third sealing disc and a second sealing disc, and the second sealing disc and the third sealing disc are respectively hermetically attached to the two connecting rings.

[0007] As a further solution of the utility model: The second filter cartridge and the first filter cartridge are arranged oppositely, and the length of the second filter cartridge is less than the length of the first filter cartridge.

[0008] As a further solution of the utility model: the outer wall of the groove is sealed against the opposite openings of the two connecting pipes, and the top of the valve stem is fixedly connected with a rotating wheel.

[0009] As a further solution of the utility model: the sealing cover is located above the second filter cartridge, and the heat conduction pipe and the first filter cartridge are located on the same connecting pipe.

[0010] As a further solution of the utility model: the valve body is made of corrosion-resistant material, and the grooves are located on both sides below the valve stem.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The liquid entering from the left side will be filtered through the second filter cartridge and then push the third sealing disc open to release the seal on the connecting ring. The third sealing disc being pushed open will stretch multiple second tension springs. At this time, the liquid will flow into the valve body and then reach the position of the first filter cartridge, and then push the second sealing disc open. At this time, the second sealing disc will also stretch multiple second tension springs and release the seal on the connecting ring, and then flow out after being filtered again through the first filter cartridge. The liquid flowing back from the left side will not be able to push the second sealing disc open from the left side, thereby preventing the liquid from flowing back. Multiple second tension springs drive the second sealing disc and the third sealing disc to always fit the opening of the connecting ring through tension, thereby preventing the circulation of liquid in the non-working state. When the pressure in the valve body and the connecting pipe is too high, the internal air pressure will lift the sealing cover, and the sealing cover will rise to release the seal on the vent hole and stretch multiple first tension springs. When the air pressure decreases, the first tension spring will drive the sealing cover back to its original position through tension to re-seal the vent hole.

[0014] The utility model is simple to use. The second sealing disk and the third sealing disk are used in conjunction with multiple second tension springs to prevent liquid backflow. After the heater is started, the heat conduction pipe, the connecting pipe, and the valve body are heated, thereby heating the liquid medium input into the connecting pipe and the valve body to maintain temperature balance. When the air pressure in the connecting pipe and the valve body is too high, the sealing cover will be lifted up to open the vent hole for pressure relief to prevent affecting the liquid circulation.

Connecting pipes 2 are connected and communicated on both sides of the valve body 1. A valve rod 7 is hermetically and rotatably connected through the top of the valve body 1. The bottom end of the valve rod 7 extends into the valve body 1 and is fixedly connected with a sealing ball 11. Two grooves 12 are symmetrically formed on the outer wall of the sealing ball 11. A vent hole 9 is formed through the top of one of the connecting pipes 2. A plurality of first tension springs 10 are arranged in an annular array on the bottom inner wall of the vent hole 9, and the tops of the plurality of first tension springs 10 are fixedly connected to the same sealing cover 8. The bottom of the sealing cover 8 is hermetically attached to the top of the vent hole 9. A plurality of heat conduction pipes 5 are fixedly connected in an annular array on the outer wall of the other connecting pipe 2, and a heater 4 is fixedly embedded on the plurality of heat conduction pipes 5. After the heater 4 is started, it will heat the plurality of heat conduction pipes 5. The plurality of heat conduction pipes 5 can conduct heat to the connecting pipe 2 for heating. The heat can be conducted to the valve body 1 and the other connecting pipe 2 through this connecting pipe 2, so as to heat the liquid medium input into the connecting pipe 2 and the valve body 1 to maintain temperature balance. Rotating the runner can drive the valve rod 7 and the sealing ball 11 to rotate. After the sealing ball 11 rotates, it can drive the groove 12 to reach the inner opening position of the connecting pipe 2, and the liquid can flow through the groove 12 and the remaining space in the valve body 1.

[0023] In this embodiment, a second filter cartridge 13 and a first filter cartridge 6 are respectively inserted through the two connecting pipes 2. Connecting rings 17 are fixedly connected to the inner walls of the second filter cartridge 13 and the first filter cartridge 6. A plurality of second tension springs 14 are annularly arranged on one side of the two connecting rings 17 facing the same direction. The ends of the plurality of second tension springs 14 on both sides away from the connecting rings 17 are respectively fixedly connected to a third sealing disc 16 and a second sealing disc 15. The second sealing disc 15 and the third sealing disc 16 are respectively in sealing contact with the two connecting rings 17.

[0024] In this embodiment, the second filter cartridge 13 and the first filter cartridge 6 are arranged oppositely, and the length of the second filter cartridge 13 is less than the length of the first filter cartridge 6.

[0025] In this embodiment, the outer wall of the groove 12 is hermetically attached to the opposite openings of the two connecting pipes 2. A runner is fixedly connected to the top of the valve stem 7.

[0026] In this embodiment, the sealing cover 8 is located above the second filter cartridge 13. The heat conducting pipe 5 and the first filter cartridge 6 are on the same connecting pipe 2. The plurality of second tension springs 14 drive the second sealing disc 15 and the third sealing disc 16 to always fit on the openings of the connecting rings 17 through the tension, thereby preventing the flow of liquid in the non-working state. When the pressure in the valve body 1 and the connecting pipe 2 is too high, the internal air pressure will lift the sealing cover 8. The sealing cover 8 will rise to release the seal of the ventilation hole 9 and stretch a plurality of first tension springs 10.

[0027] In this embodiment, the valve body 1 is made of corrosion-resistant material. The grooves 12 are located on both sides below the valve stem 7.

[0028] In this embodiment, one side of the heater 4 is electrically connected to a power supply line 3. The power supply line 3 is located on one side of the connecting pipe 2.

[0029] The working principle of the present utility model is as follows: The power supply wire 3 can be connected to a power source to supply power to the heater 4. After the heater 4 is started, it will heat a plurality of heat conduction tubes 5. The plurality of heat conduction tubes 5 can conduct heat to the connecting tube 2 for heating. The heat can be conducted to the valve body 1 and the connecting tube 2 on the other side through the connecting tube 2 on this side, so as to heat the liquid medium input into the connecting tube 2 and the valve body 1 to maintain temperature balance. Rotating the runner can drive the valve rod 7 and the sealing ball 11 to rotate. After the sealing ball 11 rotates, it can drive the groove 12 to reach the inner opening position of the connecting tube 2. The liquid can flow through the groove 12 and the remaining space in the valve body 1. The liquid flow direction needs to be from right to left. The liquid entering from the left will pass through the second filter cartridge 13 and then push open the third sealing disc 16 to release the seal on the connecting ring 17. When the third sealing disc 16 is pushed open, it will stretch a plurality of second tension springs 14. At this time, the liquid will flow into the valve body 1, then reach the position of the first filter cartridge 6, and then push open the second sealing disc 15. At this time, the second sealing disc 15 will also stretch a plurality of second tension springs 14 and release the seal on the connecting ring 17, and then flow out after being filtered again by the first filter cartridge 6. The liquid flowing back from the left cannot push open the second sealing disc 15 from the left, so the liquid reflux can be prevented. The plurality of second tension springs 14 drive the second sealing disc 15 and the third sealing disc 16 to always fit on the opening of the connecting ring 17 through the tension, so as to prevent the liquid from flowing during the non-working state. When the pressure in the valve body 1 and the connecting tube 2 is too high, the internal air pressure will lift the sealing cover 8. The sealing cover 8 will rise to release the seal on the vent hole 9 and stretch a plurality of first tension springs 10. When the air pressure decreases, the first tension springs 10 will drive the sealing cover 8 back to its original position to re-seal the vent hole 9.
