Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fluid control, in particular to an intelligent electronically controlled hydraulic valve. Background Art
[0002] A hydraulic valve is an automated component operated by pressurized oil. Controlled by a pressure-controlled valve, it is typically used in conjunction with a solenoid-operated pressure-controlled valve to remotely control the on / off flow of oil, gas, and water pipelines in hydropower stations. It is commonly used for clamping, controlling, and lubricating oil circuits. With the development of modern industry, various hydraulic valves are playing an increasingly important role in various fields.
[0003] A one-way hydraulic valve is an existing hydraulic valve composed of a valve body, a pressure spring, a valve core, etc., which only allows liquid to flow in one direction. Under long-term high pressure, the internal spring and seal are easily damaged. When the one-way valve is damaged, it is necessary to close the valves at both ends of the pipeline, interrupting the pipeline to repair the one-way valve, resulting in interruption of oil, electricity and other supplies, which is inconvenient to use. Utility Model Content
[0004] The purpose of the utility model is to solve the following shortcomings in the prior art: the internal spring and seal are easily damaged under long-term high pressure. When the one-way valve is damaged, it is necessary to close the valves at both ends of the pipeline, interrupting the pipeline to repair the one-way valve, resulting in interruption of oil, electricity and other supplies, which is inconvenient to use. An intelligent electronically controlled hydraulic valve is proposed.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] An intelligent electrically controlled hydraulic valve comprises a housing and a main pipe, wherein two main pipes are fixedly connected to both ends of the housing respectively;
[0007] The cam is fixedly mounted on the support frame of the second control unit, and the cam is fixedly mounted on the support frame of the second control unit, wherein the cam is fixedly mounted on the support frame of the second control unit.
[0008] Preferably, a compression spring is fixedly connected between the adjustment block and the accommodating cavity, and the compression spring is sleeved on the outer surface of the limiting rod.
[0009] Preferably, a one-way valve body is fixedly connected in the secondary pipeline, and both ends of the secondary pipeline are respectively threadedly connected to the main pipeline.
[0010] Preferably, two limit blocks are fixedly connected to the inner side wall of the secondary pipe, and the two limit blocks are respectively arranged on both sides of the accommodating cavity.
[0011] Preferably, a through hole is provided on the side wall of the adjusting block, and a stop block is fixedly connected to the side wall of the baffle.
[0012] Preferably, a handle is fixedly connected to the side wall of the limiting rod, a partition door is provided on the side wall of the shell, and a switch is provided on the side wall of the secondary pipe.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. The valve works by installing two auxiliary pipes in the valve. When the one-way valve in one of the auxiliary pipes fails, the reverse flow of the fluid in the pipe drives the push plate to move, driving the baffle to slide and release the limit on the regulating block, so that the regulating block moves down to close the auxiliary pipe where the one-way valve fails. The first magnet and the second magnet cooperate with each other to move the regulating block in the other auxiliary pipe downward, allowing the liquid to flow normally from the other auxiliary pipe. When one of the one-way valves fails, the pipe can still work normally without causing reverse flow of the fluid in the pipe.
[0015] 2. When one of the one-way valves in the valve fails, the other one works normally. When the failed one-way valve is repaired and replaced, the pipeline can still work normally without interrupting the supply of oil, gas and electricity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0020] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.
[0021] Reference Figure 1-Figure 2 , an intelligent electronically controlled hydraulic valve, comprising a housing 1 and a main pipe 2, wherein two main pipes 2 are fixedly connected to both ends of the housing 1. During normal operation, the fluid flows from the left main pipe 2 into the upper secondary pipe 3 and then flows out from the right main pipe 2;
[0022] An adjusting assembly is provided in the shell 1, which includes an accommodating chamber 4, a limiting rod 5, an adjusting block 6, a baffle 7, a push plate 8, a first magnet 9, a second magnet 10, and a connecting rod 11. Two auxiliary pipes 3 are fixedly connected between the two main pipes 2, and a one-way valve body 13 is fixedly connected in the auxiliary pipe 3. The flow direction of the one-way valve body 13 is only from left to right. The two ends of the auxiliary pipe 3 are respectively threadedly connected to the main pipe 2. The accommodating chamber 4 is fixedly connected in the auxiliary pipe 3, and the limiting rod 5 is slidably connected in the accommodating chamber 4. The adjusting block 6 is fixedly connected to one end of the limiting rod 5. The adjusting block 6 is sealed and slidably connected in the accommodating chamber 4. The adjusting block 6 can only slide up and down. A through hole is provided on the side wall of the adjusting block 6, which is located above The through hole of the regulating block 6 is at the lower end of the regulating block 6. When the fluid flows normally from the auxiliary pipe 3 located above, the fluid flows out normally from the through hole. When the regulating block 6 moves downward, the through hole moves down into the accommodating chamber 4. The part without the through hole seals the auxiliary pipe 3, and the fluid cannot flow through. The through hole in the regulating block 6 located below is in the center. When the fluid flows normally from the auxiliary pipe 3 located above, the fluid below is blocked by the regulating block 6 below and cannot pass through, and the auxiliary pipe 3 below does not flow. When the upper regulating block 6 moves downward, the regulating block 6 below is also driven to move downward, driving the through hole part to overlap with the auxiliary pipe 3. The fluid can flow out from the through hole of the regulating block 6 located below, and the fluid flows normally from the auxiliary pipe 3 located below.
[0023] The baffle 7 is slidably connected to the side wall of the auxiliary pipe 3, the baffle 7 is slidably connected to the adjustment block 6, the push plate 8 is hinged at one end of the baffle 7, the first magnet 9 is fixedly connected to the side wall of the baffle 7, and two limit blocks 14 are fixedly connected to the inner wall of the auxiliary pipe 3. The two limit blocks 14 are respectively arranged on both sides of the accommodating chamber 4. The side wall of the baffle 7 is fixedly connected with a stopper 15. When the fluid flows from left to right in the auxiliary pipe 3, the push plate 8 is pushed to flip under the pressure of the fluid. Under the limit of the stopper 15, a certain angle is maintained between the push plate 8 and the baffle 7. The push plate 8 gives a certain pressure to the baffle 7, so that the baffle 7 is always close to the limit block 14 on the right. The baffle 7 also limits the adjusting block 6, so that the adjusting block 6 cannot fall. When the one-way valve located above fails after long-term use, the fluid flows in the opposite direction, and the fluid flows from right to left. The fluid pushes the push plate 8 to rotate, and the push plate 8 flips from right to left. After the inclined push plate 8 rotates to the vertical state, it reaches the maximum rotation range. The push plate 8 temporarily seals the auxiliary pipe 3 above. At the same time, the push plate 8 drives the baffle 7 to slide to the left under the impact force of the fluid until it contacts the left The baffle 7 slides to the left to release the limit on the adjusting block 6. The adjusting block 6 slides downward under the action of the extrusion spring 12. The part with the through hole slides to the bottom of the accommodating chamber 4. The solid part above seals the auxiliary pipe 3, and the fluid no longer circulates. The auxiliary pipe 3 located above stops working. The side wall of the auxiliary pipe 3 is provided with a slide groove, and the second magnet 10 is slidably connected in the slide groove. The connecting rod 11 is fixedly connected between the two second magnets 10. When the upper baffle 7 slides to the left, it drives the upper first magnet 9 to slide The first magnet 9 slides, driving the second magnet 10 to slide, driving the sliding rod connecting rod 11 to slide, the connecting rod 11 slides, driving the first magnet 9 and the second magnet 10 below to slide, and the first magnet 9 below slides to the left, driving the baffle 7 below to slide to the left, and the baffle 7 below slides to the left to release the limit on the lower adjusting block 6. The adjusting block 6 slides downward under the action of the extrusion spring 12, and the part with the through hole slides to the position of the auxiliary pipe 3 below. The fluid can pass through the through hole of the adjusting block 6 below, and the auxiliary pipe 3 below can circulate normally.
[0024] An extrusion spring 12 is fixedly connected between the adjustment block 6 and the accommodating chamber 4. The extrusion spring 12 is sleeved on the outer surface of the limit rod 5. A handle 16 is fixedly connected to the side wall of the limit rod 5. A partition door is provided on the side wall of the shell 1, and a switch is provided on the side wall of the auxiliary pipe 3. When the connecting rod 11 slides to the left, it pushes the switch, and the prompt light will light up to indicate that maintenance is needed. The device can be repaired by opening the partition door.
[0025] When the valve is in the upper side, the valve 1 is in the closed position, and the valve 1 is in the closed position, so the valve 1 is in the closed position, and the valve 1 is in the closed position, so the valve 1 is in the closed position, and the valve 1 is in the closed position, so the valve 1 is in the closed position, and the valve 1 is in the closed position, so the valve 1 is in the closed position, and the valve 1 is in the closed position, so the valve 1 is in the closed position, and the valve 1 is in the closed position, so the valve 1 is in the closed position, and the valve 1 is in the closed position, so the valve 1 is in the closed position, and the valve 1 is in the closed position, so the valve 1 is in the closed position, and the valve 1 is in the closed position, so the valve 1 is in the closed position, and the valve 1 is in the closed position, so the valve 1 is in the closed position, and the valve 1 is in the closed position, so the valve 1 is in the closed position, and the valve 1 is in the closed position, so the valve 1 is in the closed position, and the valve 1 is in the closed position, so the valve 1 is in the closed position, and the valve The secondary pipeline 3 is completely sealed, and at the same time, the baffle 7 located above drives the first magnet 9 to slide when sliding, and the sliding of the first magnet 9 drives the second magnet 10 to slide, which drives the connecting rod 11 to slide, and the sliding of the connecting rod 11 drives the second magnet 10 located below to slide. The sliding of the second magnet 10 below drives the first magnet 9 below to slide, and the sliding of the first magnet 9 below releases the limit on the adjusting block 6 below. The adjusting block 6 below slides downward, and the fluid flows out from the through hole of the adjusting block 6 below. The secondary pipeline 3 located below begins to circulate, and the fluid circulates normally from the secondary pipeline 3 located below, and a prompt is issued to remind the staff that the one-way valve above has failed and needs to be replaced in time.
