Description

Technical Field

[0001] The invention relates to the technical field of high-speed hydraulic valves, and in particular to an automated high-speed hydraulic valve with strong adaptability. Background Art

[0002] The operation of mechanical equipment is generally controlled by oil pressure, in which hydraulic valves are used. Hydraulic valves are an automation component operated by pressure oil. The control of the oil circuit is generally controlled by electromagnetic hydraulic valves. Electromagnetic hydraulic valves are simple to install, easy to maintain, and cheap. Therefore, in electro-hydraulic control systems, solenoid valves play an important role and are suitable for the push and retraction switching of hydraulic rods of various mechanical equipment. However, the existing hydraulic valves still have the following problems when used:

[0003] The existing electromagnetic hydraulic valve controls the internal valve core to be pushed to switch the hydraulic oil circuit through two sets of electromagnetic coils. When the electromagnetic coil fails, it is necessary to manually push the manual lever to switch the oil circuit, which is inconvenient to use. In addition, the electromagnetic coil pushes the guide rod to push the valve core to move, which can only complete the positioning movement of the valve core, and the hydraulic oil speed cannot be adjusted. It needs to be used in conjunction with a speed regulating valve.

[0004] After the existing hydraulic oil has been used for a period of time, the viscosity of the oil will increase, and the impurities in the oil will accumulate inside the hydraulic valve, causing the oil circuit to be blocked. When the hydraulic oil is purified by the existing filter element, the filter element needs to be removed and replaced regularly, causing the equipment to be shut down and the replacement of the filter element takes a long time, which is inconvenient to use;

[0005] The existing hydraulic valve is affected by the speed regulation and may cause high internal pressure. It needs to be used with a pressure relief structure. When the pressure is high, oil leakage may also occur between the hydraulic valve and the connecting pipe. For this reason, we propose an automated high-speed hydraulic valve with strong adaptability. Summary of the invention

Beneficial Effects

[0022] The present invention provides an automatic high-speed hydraulic valve with strong adaptability, which has the following beneficial effects:

[0023] (1) The highly adaptable automated high-speed hydraulic valve is provided with a valve body assembly and an electronic control assembly. The electronic control assembly can, when the electromagnetic coil module is working, enable the first electric push rod to assist the sliding of the limit valve core to adjust the gap between the oil inlet chamber and the oil outlet chamber to complete the hydraulic oil speed adjustment. At the same time, when the electromagnetic coil module is damaged, the first electric push rod can be used to assist the valve core switching operation. In this way, the oil speed adjustment of the hydraulic valve is realized so that the hydraulic rod can adjust the extension and retraction speed according to the demand, so that it does not need to be used with an external speed regulating valve, saving the use cost and parts, and ensuring that the electromagnetic coil module is damaged and the oil circuit operation can still be automatically switched, ensuring the normal operation of the equipment without manual operation.

[0024] (2) The highly adaptable automatic high-speed hydraulic valve is provided with an electric control component, a cleaning component, a pressure relief component and a sealing component. When the cleaning component is in normal use, the filter block can clean and filter the hydraulic oil. At this time, the first clamping block and the second clamping block in the sealing component are constrained by the sealing plate to squeeze the first sealing block and the second sealing block to improve the sealing effect, thereby ensuring the sealing of the inlet and outlet oil; the two groups of first electric push rods in the electric control component are sequentially driven, so that the blocking cylinder in the cleaning component rotates clockwise in sequence to connect the cleaning groove, and the high-pressure clean hydraulic oil is connected to the oil circuit through the electric control ball valve in the pressure relief component. The oil circuit is switched to enter the oil outlet cavity from the pressure relief pipe, so that the hydraulic oil can flow from the inside of the filter block to remove impurities on the side of the flusher. At the same time, the trigger block in the sealing component unlocks the fourth spring, so that the flushed hydraulic oil can enter the waste oil tank through the linkage block, thereby ensuring the cleanliness of the hydraulic valve during use. After a fixed time of use, the hydraulic valve can perform self-cleaning operation to avoid the hydraulic valve being too dirty and affecting the use of the oil circuit.

[0025] (3) The highly adaptable automated high-speed hydraulic valve is provided with a pressure relief component and a sealing component. When the oil pressure of the pressure relief component is too high, the internal pressure block is forced out of the first fixed block by external force, so that the hydraulic oil can be connected to the return oil outlet chamber through the pressure relief pipe for pressure relief. At the same time, a pressure detector is provided inside the installation chamber. When the pressure is too high and continues for more than a set time, the trigger block inside the sealing component is disengaged from the fourth spring, so that the hydraulic oil can enter the waste oil tank through the oil drain groove to complete auxiliary pressure relief. At the same time, the one-way rod inside the oil inlet groove is oppositely arranged to complete a similar one-way valve to prevent the hydraulic oil from flowing back into the oil inlet groove. In this way, it is ensured that the internal pressure of the hydraulic valve will not be too high, and damage to the hydraulic valve and oil leakage due to excessive pressure can be avoided.

[0058] Working principle of the present invention:

[0059] During normal use, as shown in the valve body assembly 18 and the valve body assembly 19, the valve body assembly 1 switches the oil circuit normally, the electronic control assembly 2 drives and adjusts the oil speed, the cleaning assembly 3 performs normal filtering and cleaning, the pressure relief assembly 4 performs normal oil return state, and the sealing assembly 5 seals the interface. Specifically: the electromagnetic coil module 21 on one side is energized to drive the internal guide rod 23 to slide inside the guide cavity 221, pushing the valve core 16 to slide and switch inside the installation cavity 12, so that one group of oil outlet cavities 14 is connected to the oil inlet cavity 13, and the other group of oil outlet cavities 14 is connected to the oil return cavity 15. The hydraulic oil is transported into the oil inlet groove 131 through the oil pump, and the hydraulic oil is filtered by the filter block 31 for impurities. The hydraulic oil is discharged from the oil inlet cavity 13 to the connected oil outlet The inside of the chamber 14 is discharged from the corresponding oil outlet groove 141 to the inside of the hydraulic rod oil chamber. When the synchronous hydraulic rod is pushed, the oil chamber on the other side returns the hydraulic oil from another group of oil outlet grooves 141 to the inside of the other group of oil outlet chambers 14, and then returns the oil from the inside of the return oil chamber 15 through the return oil groove 151 to the inside of the oil tank, completing the pushing or contraction movement of the hydraulic rod. When the oil outlet groove 51 on one side is energized, the first electric push rod 28 on the other side pushes the manual rod 26 to force the guide rod 23 to reach the predetermined position, so that the valve core 16 is limited when being pushed, so as to adjust the gap size at the connection point between the oil inlet chamber 13 and the oil outlet chamber 14, and adjust the hydraulic oil flow rate so that the pushing speed of the hydraulic rod can be adjusted; wherein, before the first electric push rod 28 is installed, it is threadedly installed on the installation block 271 The first electric push rod 28 is driven to perform telescopic movement inside the groove 27. When the detection block 281 contacts the matching block 261 and obtains a signal, it is set to zero position, which is convenient for the subsequent first electric push rod 28 to accurately push the manual rod 26. When the guide rod 23 on one side pushes the valve core 16, the guide rod 23 pushes the trigger rod 341 to slide inside the trigger chamber 34 constrained by the constraint block 342, so that the second movable block 332 contacts and squeezes the first movable block 331. At this time, the second movable block 332 only pushes the first movable block 331 to rotate clockwise or counterclockwise by a certain angle, and the movable rod 322 drives the blocking cylinder 321 to rotate. At this time, the cleaning groove 36 is not connected. When the electromagnetic coil module 21 is not energized, the first spring 25 elastically Under the support, the limit ring 24 constrains the valve core 16 to reset to the center position of the installation chamber 12, and the trigger rod 341 and the movable rod 322 reset under the elastic force of the second spring 343 and the torsion spring 323; at the same time, the second electric push rod 542 pulls the sealing plate 54 so that the first clamping block 53 is inside the matching groove 541, and the trigger block 57 is squeezed on the side of the fourth spring 564, so that the first clamping block 53 and the second connecting block 52 are squeezed to squeeze the first sealing block 531 to form a seal, and the linkage block 562 is squeezed on the side of the one-way rod 551 at the corresponding position to limit and close the oil drain groove 51 oil circuit, and when the electromagnetic coil module 21 fails, the first electric push rod 28 can be used to forcibly push the manual rod 26 to make the guide rod 23 slide and switch the oil circuit for use.

[0060] When the oil pressure is too high, as shown in the electronic control component 20, the valve body component 1 switches the oil circuit normally, the electronic control component 2 drives and adjusts the oil speed, the cleaning component 3 performs normal filtering and cleaning, the pressure relief component 4 performs connected pressure relief, and the sealing component 5 performs auxiliary pressure relief. Specifically: when the oil circuit is switched normally and the oil speed is adjusted as above, the oil pressure inside the installation cavity 12 is too high. At this time, the internal pressure of the oil outlet cavity 14 connected to the oil inlet cavity 13 is too high, and the corresponding position pressure block 46 is squeezed to deform the third spring 49. The pressure block 46 is constrained by the pressure relief rod 48 to slide out of the first fixed block 45 to the connected oil circuit, and the hydraulic oil is discharged into the pressure relief pipe 42 to the position of another group of oil outlet chambers 14. At this time, the corresponding pressure block 46 is also pushed by the hydraulic oil to slide out of the first fixed block 45 in the opposite direction, so that the hydraulic oil of the oil outlet chamber 14 of the oil inlet is discharged from the pressure relief pipe 42 into the oil outlet chamber 14 of the return oil. The pressure is released. At this time, the electric-controlled ball valve 43 electrically opens the oil circuit at the oil outlet pipe 152 and closes the oil circuit of the connecting pipe 44. A pressure detector is arranged inside the synchronous installation chamber 12. After the pressure is too high and continues for more than the set time, the second electric push rod 542 pushes the sealing plate 54 to move upward. At this time, the trigger block 57 disengages from the side position of the limit block 563. The fourth spring 564 elastically pushes the limit block 563 to drive the linkage block 562 to move accordingly. The linkage block 562 slides to the position of the second sealing block 561. At this time, the hydraulic oil inside the oil inlet chamber 13 can enter the oil drain groove 51 to push the one-way rod 551 to slide. The hydraulic oil is discharged from the inside of the second fixed block 55 and enters the linkage block 562. From its side oil pipe, it enters the waste oil tank to complete the auxiliary pressure relief. The one-way rod 551 inside the synchronous oil inlet groove 131 is arranged in the opposite direction to complete a similar one-way valve to prevent the hydraulic oil in the oil inlet groove 131 from flowing back.

[0061] During self-cleaning, as shown in the electromagnetic coil module 21, the valve body assembly 1 resets the oil circuit, the electronic control assembly 2 switches the drive, the cleaning assembly 3 switches the oil circuit to the self-cleaning state, the pressure relief assembly 4 switches the closed oil return, and the sealing assembly 5 discharges the waste oil. Specifically: the two sets of electromagnetic coil modules 21 are in a non-energized state, the electronically controlled ball valve 43 is electronically switched so that the oil outlet pipe 152 closes the connecting pipe 44 and is in an open state, and the valve core 16 is reset and set in the 12-shaped position of the installation cavity. At this time, the first electric push rod 28 on the left side is energized to push the guide rod 23 to squeeze the trigger rod 341 at the corresponding position so that the second movable block 332 pushes the first movable block 331 to rotate a certain angle in the clockwise direction. At this time, the first movable block 331 on the other side rotates accordingly to the previous position of the first movable block 331, and then the first electric push rod 28 on the right side is energized to push the second movable block 332 to contact the first movable block 331 at this time, and the second movable block 332 can continue to push the first movable block 331 to rotate a certain angle in the clockwise direction. At this time, the movable rod 322 drives the blocking cylinder 321 to rotate so that the cleaning groove 36 is in a connected state, and the side of the electric control ball valve 43 is connected with high-pressure impurity-free hydraulic oil, and the hydraulic oil passes from the connecting pipe 44 through the pressure relief pipe 42 to the inside of the oil outlet chamber 14. The hydraulic oil in the oil outlet chamber 14 enters the inside of the cleaning chamber 32 from the corresponding cleaning groove 36 and then is discharged from the cleaning groove 36 at the corresponding position of the filter block 31. At this time, the sealing plate 54 is pushed by the second electric push rod 542 to push the trigger block 57 away from the side position of the limit block 563. The hydraulic oil is discharged from the inner side of the filter block 31 to flush the impurities on the side of the filter block 31. The oil is discharged from the inside of the oil drain groove 51 inside the oil inlet chamber 13 and flows to the waste oil tank. The inside of the oil inlet groove 131 is one-way blocked, and the oil outlet groove 141 is in a constant pressure blocked state because there is oil inside the hydraulic rod cylinder at this time. The second electric push rod 542 pushes the sealing plate 54 completely upward, and the first clamping block 53 and the second clamping block 56 slide out of the matching groove 541 without restraint, and the first clamping block 53 and the second clamping block 56 can be directly pulled out for disassembly.
