Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hydraulically controlled water valves, and in particular relates to an oil-water immiscible slide valve type hydraulically controlled water valve. Background Art
[0002] The oil-water immiscible slide valve type hydraulically controlled water valve is a specially designed valve that combines the working principle of the slide valve with the advantages of hydraulic control technology and is used to control the water flow in the oil-water immiscible system.
[0003] The operating principle of a spool-type hydraulically controlled water valve is to control the flow of fluids or regulate flow through the sliding motion of a spool. When a control signal is applied to the hydraulic control system, the hydraulic pressure pushes the spool within the valve body, thereby changing the flow path of the fluid. In oil-water immiscible systems, this valve effectively prevents the interpenetration of oil and water, ensuring normal system operation.
[0004] The spool portion of a spool-type hydraulically controlled water valve is typically designed with a precise clearance to ensure smooth sliding and sealing between the valve core and the valve body. However, when the feed water contains a large amount of impurities, these impurities can easily enter the spool clearance. Due to the varying size, shape, and hardness of these impurities, they can create friction and resistance during spool movement, directly hindering smooth spool motion. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Example 1
[0024] See also Figure 1-6 The utility model provides the following technical solutions: an oil-water non-mixing sliding valve type hydraulically controlled water valve, comprising a valve body 6, end covers 2 being installed at both ends of the valve body 6, the outer side walls of the two end covers 2 being connected to a spring seat 1, a water valve core 5 and a sealing member 7 being assembled inside the valve body 6, a control piston 4 being assembled inside the end covers 2, a return spring 3 being assembled inside one of the end covers 2, a first water inlet hole 9 and a second water inlet hole 10 being opened at the top of the valve body 6, a first oil filling hole 11 and a second oil filling hole 12 being opened on both sides of the top of the valve body 6, a positioning ring 13 and a support ring 14 being connected inside the first water inlet hole 9 and the second water inlet hole 10, and a filter cartridge 15 being arranged inside the first water inlet hole 9 and the second water inlet hole 10.
[0025] In the preferred embodiment, the diameter of the inner ring of the support ring 14 is smaller than the diameter of the inner ring of the positioning ring 13 , and the diameter of the inner ring of the positioning ring 13 is adapted to the size of the bottom end of the filter cartridge 15 .
[0026] In the preferred embodiment, a sealing ring 18 is connected to the outer side wall of the top end of the filter cartridge 15 , and a positioning bolt 17 is installed at the top end of the filter cartridge 15 .
[0027] In the preferred embodiment, the filter cartridge 15 is fixed to the positioning ring 13 by means of a threaded connection between the positioning bolts 17 , and a threaded groove adapted to the positioning bolts 17 is formed on the top of the positioning ring 13 .
[0028] In the preferred embodiment, the distance between the positioning ring 13 and the support ring 14 is the same as the height of the filter cartridge 15 , and the bottom end of the filter cartridge 15 is supported on the top end of the support ring 14 . A semicircular guide groove 16 is provided on the outer side wall of the support ring 14 .
[0029] In the embodiment, the application of the filter cartridge 15 effectively filters the liquid flowing in from the first water inlet hole 9 and the second water inlet hole 10, significantly reducing the accumulation of impurities inside the valve body 6, thereby preventing impurities from invading the gap between the control piston 4 and the valve body 6, reducing the wear of the control piston 4 caused by this, and ensuring that the normal operation of the control piston 4 is not affected.
[0030] Specifically, during operation, the valve body 6 receives liquid from the first and second water inlet holes 9, 10. This liquid first flows through the first and second water inlet holes 9, 10, and is then introduced into the filter cartridge 15. After being finely filtered by the filter cartridge 15, the liquid flows out through the mesh opening of the filter cartridge 15. A portion of the liquid flows along the outer wall of the filter cartridge 15 and smoothly enters the interior of the valve body 6 through the guide groove 16; another portion of the liquid flows directly into the valve body 6 from the bottom of the filter cartridge 15. This design significantly reduces the accumulation of impurities inside the valve body 6, effectively preventing impurities from invading the gap between the control piston 4 and the valve body 6, thereby reducing wear on the control piston 4 and ensuring its normal operation without interference.
[0031] In addition, the filter cartridge 15 is firmly fixed between the positioning ring 13 and the support ring 14 by the threaded connection between the positioning bolts 17 and the positioning ring 13. When the filter cartridge 15 is blocked, the positioning bolts 17 are simply removed to easily replace the filter cartridge 15 and continue to be put into use.
[0032] Example 2
[0033] See also Figure 1-6 A drain hole 8 is provided at the bottom end of the valve body 6, a drainage pipe 19 is connected to the bottom end of the end cover 2, a sealing valve 20 is installed at the end of the drainage pipe 19, and a temperature sensor 21 is installed on the surface of the drainage pipe 19.
[0034] In this embodiment, the introduction of drainage tube 19 and the installation of temperature sensor 21 allow easy drainage of control oil from first and second oil inlet holes 11, 12 via drainage tube 19, facilitating inspection of the control oil's condition and timely replacement to maintain efficient system operation. Furthermore, temperature sensor 21 monitors the control oil's temperature in real time, effectively preventing thermal degradation of the seal 7 within valve body 6 due to excessive oil temperature, further enhancing the durability and reliability of the entire system.
[0035] Specifically, during operation, valve body 6 receives control oil through first and second oil inlet holes 11, 12, which then flows into drainage tube 19. After use, temperature sensor 21 monitors and provides real-time feedback on the oil temperature, effectively preventing the risk of excessive oil temperature causing thermal degradation of seals 7 within valve body 6. Furthermore, opening sealing valve 20 allows for smooth drainage of the control oil from drainage tube 19, making it easier for operators to check the condition of the control oil and replace it promptly when necessary.
[0036] In summary, according to the descriptions of Examples 1 and 2, the filter cartridge 15 effectively filters the liquid in the first and second water inlet holes 9, 10, reducing impurities within the valve body 6 and preventing them from entering the clearance of the control piston 4, thereby reducing wear and ensuring proper operation. The addition of the drainage tube 19 and temperature sensor 21 facilitates the removal of control oil through the first and second oil inlet holes 11, 12, facilitating inspection and replacement. Furthermore, the oil temperature is monitored to prevent thermal aging of the seal 7, thereby enhancing the durability and reliability of the hydraulically controlled water valve.
[0037] It should be noted that: Reference Figure 1 The specific operating principle of the oil-water non-mixing spool-type hydraulically controlled water valve is as follows: the return spring 3 places the water valve core 5 in a predetermined initial state. Specifically, the water valve core 5 is on the right side of the valve body 6, and the first oil inlet 11 is filled with control oil. The water valve core 5 remains in the initial state, and the first water inlet 9 and the second water inlet 10 are disconnected. When the first oil inlet 11 is unloaded and the second oil inlet 12 is filled with control oil, the water valve core 5 switches direction and moves to the left, connecting the first water inlet 9 and the second water inlet 10.
[0038] It is worth mentioning that: Figure 1 A control piston 4 is provided between the first water inlet hole 9 and the first oil filling hole 11, and a seal is connected to the surface of the control piston 4. When water enters the first water inlet hole 9, the water pressure will not invade the first oil filling hole 11 from the control piston 4, so as to ensure that the oil and water will not mix. Similarly, the same is true between the second water inlet hole 10 and the second oil filling hole 12. The seal connected to the surface of the control piston 4 is used to prevent the oil and water from mixing.
[0039] In addition, also refer to Figure 1The bottom end of the valve body 6 is provided with a drain hole 8, and then two seals are connected to the surface of the control piston 4. In this way, if the first oil filling hole 11 invades the gap of the control piston 4, it will be blocked by the second seal. Then, when the control piston 4 moves to the right, the invading oil can be discharged from the drain hole 8. Similarly, the water entering the valve body 6 from the first water inlet hole 9 invades the gap of the control piston 4, and will also be discharged from the drain hole 8 when the control piston 4 moves to the left.
[0040] The same is true between the second water inlet 10 and the second oil filling hole 12 .
[0041] refer to Figure 2 , Figure 2 The original water control valve lacks a control piston 4 and a drain hole 8, so when the valve body 6 is subjected to high pressure, it is easy to cause oil and water to mix.
[0042] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
