Description

Technical Field

[0001] This invention relates to the field of valve technology, specifically to a valve capable of automatically dispensing liquid. Background Technology

Additionally, in existing technologies, when valves are in use, it is necessary to monitor the internal pressure in real time, but current technologies cannot effectively install sensors, resulting in reduced ease of use.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] Please see Figure 1-8An automatic liquid inlet valve includes a valve body 1, on which a control mechanism and a rust prevention mechanism are provided. The control mechanism includes a valve plate 2, a lifting rod 3, a first fixed plate 4, connecting bolts 5, an inner sealing tube 6, a limiting edge 7, a sealing head 8, a threaded sleeve 9, and a sealing seat 10. The valve plate 2 is mounted on the valve body 1, and the first fixed plate 4 is connected to the valve plate 2. Multiple connecting bolts 5 are provided, and each of the multiple connecting bolts 5 passes through the first fixed plate 4 and is threaded onto the valve plate 2. The inner sealing tube 6 is equipped with a limiting edge 7, which passes through the first fixed plate 4 and is fitted against the first fixed plate 4. The lifting rod 3 is slidably connected to the inner sealing tube 6, and a sealing head 8 is installed at the lower end of the lifting rod 3. A sealing seat 10 is installed on the threaded sleeve 9. A sleeve 9 is threaded onto the valve body 1, and a sealing head 8 is fitted onto a sealing seat 10. The valve body 1 is provided with a discharge pipe 11, a feed pipe 12, and a flange 13. The feed pipe 12 and the discharge pipe 11 are respectively connected to the valve body 1, and flanges 13 are respectively installed on the feed pipe 12 and the discharge pipe 11. A monitoring mechanism is provided on the valve body 1. The first fixed plate 4 is provided with a second fixed plate 14, a sealing nut 15, and a fixing bolt 16. The lifting rod 3 passes through the second fixed plate 14, and the fixing bolt 16 passes through the second fixed plate 14 and is threaded onto the first fixed plate 4. The sealing nut 15 is slidably connected to the lifting rod 3 and is threaded onto the second fixed plate 14. The second fixed plate 14 is provided with a side plate 17, a connecting column 18, and a sealing shell 19. The side plate 17... There are two side plates 17, each mounted on the second fixed plate 14. Each side plate 17 is connected to a connecting post 18, which is connected to a sealing shell 19. The sealing shell 19 has a sealing cover 20, a lifting plate 21, and a guide block 22. The sealing cover 20 is mounted on the sealing shell 19, and bolts are connected to the sealing cover 20 and the sealing shell 19 respectively. The lifting plate 21 is slidably connected to the sealing shell 19. The guide block 22 is installed inside the sealing shell 19. The lifting plate 21 has a guide groove 23, which is slidably connected to the guide block 22. The lifting plate 21 has a receiving nut 24, and the lifting rod 3 has a handwheel 25. There are two receiving nuts 24, which are threadedly connected to the receiving rod respectively. Two receiving nuts 24 are respectively attached to the receiving plate, and the handwheel 25 is threadedly connected to the lifting rod 3 and attached to the sealing cover 20.

Multiple springs 26 are provided, and multiple springs 26 are respectively connected to the sealing cover 20 and the lifting plate 21. The air outlet pipe 27 is connected to the lower end face of the sealing shell 19. First, the feed pipe 12 and the discharge pipe 11 are connected to the external equipment through the flange 13. When liquid exceeding the limit pressure flows into the valve body 1, the liquid will push the sealing head 8 to move upward. Since the sealing head 8 is installed on the lifting rod 3, and the lifting rod 3 is connected to the lifting plate 21, the guide groove 23 on the lifting plate 21 will slide along the guide block 22.This will then cause multiple springs 26 to move upwards, thus opening the valve and achieving automatic liquid inlet. When manual opening is required, simply turn the handwheel 25. Since the handwheel 25 is threaded onto the lifting rod 3, it will move the lifting rod 3 upwards, simultaneously causing the lifting plate 21 to compress the springs 26, thereby opening the valve and completing the opening process.

[0031] The rust prevention mechanism includes a rust-proof plate 28, a rust-proof battery 29, a cathode tube 30, and an anode tube 31. The rust-proof plate 28 is mounted on the valve body 1, and the rust-proof battery 29 is mounted on the rust-proof plate 28. The cathode tube 30 is electrically connected to the cathode of the rust-proof battery 29 and the valve body 1, respectively. The anode tube 31 is electrically connected to the anode of the rust-proof battery 29. The anode tube 31 is provided with a mounting seat 32 and an active block 33. The mounting seat 32 is mounted on the anode tube 31, and the active block 33 is snapped into the mounting seat 32 and electrically connected to the anode tube 31. During the rust prevention process, since the cathode tube 30 is electrically connected to the valve body 1 and the cathode of the rust-proof battery 29, the cathode of the rust-proof battery 29 provides electrons that are conducted to the valve body 1, reducing the degree of corrosion of the valve body 1. Through the electrons provided by the active block 33, the rust-proof battery 29 generates a potential difference, thereby completing the rust prevention process.

[0032] The monitoring mechanism includes an installation pipe 34, a detection pipe 35, a leak-proof plate 36, and a leak-proof gasket 37. The installation pipe 34 is connected to the valve body 1. The leak-proof plate 36 is installed on the detection pipe 35, and the leak-proof gasket 37 is installed on the leak-proof plate 36. The detection pipe 35 has a leak-proof groove 38 and is threaded into the installation pipe 34. The leak-proof gasket 37 is attached to the installation pipe 34. The detection pipe 35 has a sensor mounting hole 39, and a corresponding sensor is installed in the sensor mounting hole 39. The detection pipe 35 has a hexagonal segment 40 and a wire 41, and the hexagonal segment 40 is installed on the detection pipe 35. The wire 41 is installed inside the hexagonal segment 40 and is electrically connected to the sensor and the external device respectively. During the detection, the sensor is first installed in the sensor mounting hole 39. The sensor is preferably a Cyt206. The sensor is electrically connected to the wire 41 and the wire 41 is connected to the external device. Then, the detection tube 35 is threaded to the mounting tube 34. A sealing strip is installed in the anti-leakage groove 38 and is attached to the inside of the mounting tube 34. The anti-leakage gasket 37 is attached to the side of the mounting tube 34. The internal pressure is detected by the sensor to complete the whole process.

[0033] Example 2:

[0034] Please see Figure 1-8Based on Example 1, the inlet pipe 12 and outlet pipe 11 are first connected to external equipment via flange 13. When liquid exceeding the limit pressure flows into valve body 1, the liquid pushes the sealing head 8 upward. Since the sealing head 8 is mounted on the lifting rod 3, which is connected to the lifting plate 21, the guide groove 23 on the lifting plate 21 slides along the guide block 22, which in turn drives multiple springs 26 to move upward, thus opening the valve and achieving automatic liquid inlet. When manual opening is required, simply turn the handwheel 25. Since the handwheel 25 is threadedly connected to the lifting rod 3, This can drive the lifting rod 3 to move upward, which in turn drives the lifting plate 21 to compress the spring 26, and then open the valve, thus completing the opening process. When performing the test, first install the sensor in the sensor mounting hole 39. The sensor is preferably a CYT206. The sensor is electrically connected to the wire 41, which is connected to an external device. Then, the detection tube 35 is threaded onto the mounting tube 34. A sealing strip is installed in the anti-leakage groove 38 and is attached to the inside of the mounting tube 34. The anti-leakage gasket 37 is attached to the side of the mounting tube 34. The internal pressure is detected by the sensor, thus completing the entire process.

[0035] Example 3:

[0036] Please see Figure 1-8 Based on Example 2, during the rust prevention process, since the cathode tube 30 is electrically connected to the valve body 1 and the cathode of the rust-preventing battery 29, the cathode of the rust-preventing battery 29 provides electrons to the valve body 1, reducing the degree of corrosion of the valve body 1. Through the active block 33 providing electrons, the rust-preventing battery 29 generates a potential difference, thereby completing the rust prevention process.
