Description

Technical Field

[0001] This invention relates to the field of valve technology, specifically to an ultra-high pressure solenoid valve based on underwater detection. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation systems used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems, used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. The most common are check valves, safety valves, directional control valves, and speed control valves. They mainly consist of an electromagnetic coil, valve core, valve body, return spring, and seals.

[0003] Existing ultra-high pressure solenoid valves used in underwater detection equipment have an inherent characteristic of excessively short valve closing response time. During the rapid valve closing process, a sudden change in the flow velocity of the liquid in the pipeline is triggered, and the fluid momentum is instantly converted into a high-pressure water jet shock wave, which reciprocates between the valve body and the inner wall of the pipeline. This impact load easily causes the valve body to deviate and sway. On the one hand, this causes continuous wear on the mating surface between the valve body and the pipeline. After the mating accuracy is lost, it is easy to cause the valve body's valve closing sealing performance to deteriorate. On the other hand, the swaying of the valve body will simultaneously cause the valve stem to wobble, which will lead to a rigid collision between the valve body and the solenoid coil frame, which can easily cause structural damage to the components and affect the long-term operational reliability and service life of the solenoid valve.

[0004] To address the aforementioned issues, innovative design based on existing methods is urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide an ultra-high pressure solenoid valve based on underwater detection, in order to solve the technical problem in the prior art where, during the rapid closing process of the solenoid valve body, a sudden change in the flow velocity of the liquid in the pipeline is caused, and the fluid momentum is instantly converted into a high-pressure water hammer shock wave, which reciprocates between the valve body and the inner wall of the pipeline, causing continuous wear on the mating surface of the valve body and the pipeline, and the loss of fitting accuracy directly leads to the deterioration of the valve body's sealing performance when closing the valve. This invention provides a solution that is significantly different from the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ultra-high pressure solenoid valve based on underwater detection, comprising a connecting pipe, an electrically controlled valve stem mounted above the connecting pipe, a piston plate connected to the bottom end of the electrically controlled valve stem, the piston plate being slidably connected to the connecting pipe, a sealing block connected to the bottom of the piston plate, a conical groove formed on the inner side of the piston plate, a buffer block slidably connected to the conical groove, a transmission rod rotatably connected to the piston plate, the transmission rod being threadedly connected to the buffer block, and a rotating groove composed of curves and straight lines formed on the transmission rod. The inner wall of the connecting pipe is connected to a flow frame, and the flow frame is connected to the conical groove of the piston plate through a corrugated pipe. The outer side of the connecting pipe is connected to a buffer frame, and the flow frame is connected to the buffer frame. The buffer frame is connected to the connecting pipe through a flexible tube. A buffer plate is slidably connected to the inner side of the buffer frame. A fixed plate is connected to the inner side wall of the connecting pipe. An adjusting rod is rotatably connected to the fixed plate. A transmission plate is threadedly connected to the adjusting rod. The transmission plate has a hole, and a semi-circular protrusion is provided in the hole. The semi-circular protrusion is located in the rotation groove of the transmission rod. A reinforcing component is disposed inside the connecting pipe, and an adjusting component is disposed above the fixing plate.

[0007] Preferably, the reinforcing component includes a cross bar slidably connected above the transmission rod, a threaded rod connected to the top of the cross bar, an L-shaped rotating plate connected above the fixing plate and rotatably connected to the threaded rod, a lifting plate threadedly connected to the threaded rod, a compression ring connected above the lifting plate, a sealing frame connected to the bottom of the piston plate, a rubber pad provided inside the sealing frame and fitting against the compression ring.

[0008] Preferably, the adjusting assembly includes a waterproof motor connected to the outside of a connecting pipe, a rotating rod connected to the output end of the waterproof motor, and the rotating rod being rotatably connected to the connecting pipe. The rotating rod is connected to the adjusting rod via a bevel gear set.

[0009] Preferably, a sliding rod is connected to the inner side of the piston plate, and the sliding rod is slidably connected to the buffer block.

[0010] Preferably, a one-way valve is connected above the water inlet end of the connecting pipe, and the one-way valve is connected to the buffer frame through a hose. A one-way valve is provided at the connection between the flow frame and the buffer frame.

[0011] Preferably, a spring is connected to the top of the buffer plate, and the top of the spring is connected to the top of the inner side of the buffer plate.

[0012] Preferably, there are two sets of buffer blocks, and the bottom surface of both sets of buffer blocks is sloping.

[0013] Preferably, a guide rod is connected above the flow frame, and the guide rod is slidably connected to the lifting plate.

[0014] Preferably, a limiting rod is connected above the transmission plate, and the limiting rod is slidably connected to the fixed plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, when the piston plate moves downward to close the connecting pipe, it drives the transmission rod to rotate. The rotation of the transmission rod drives the buffer block to move upward, gradually opening the conical groove at the bottom of the sealing block. The impacting water flow can enter the inner side of the buffer frame through the gradually opening conical groove, thereby reducing the water flow pressure when the sealing block is closed and reducing the occurrence of damage to the sealing block and piston plate due to impact force. Furthermore, the buffer solution stored inside the buffer frame will flow back to the inlet end of the connecting pipe under the action of the spring.

[0016] 2. In this invention, the rotation of the transmission rod drives the rotation of the threaded rod, which in turn drives the vertical movement of the lifting plate. The movement of the lifting plate drives the movement of the extrusion ring, which in turn moves upward to extrude the rubber pad so that it fits tightly against the outside of the electric control valve stem. The rubber pad reinforces the valve stem and reduces the amplitude of the valve stem's sway due to water flow.

[0017] 3. In this invention, starting the waterproof motor drives the rotating rod to rotate. The rotation of the rotating rod adjusts the height of the transmission plate, thereby adjusting the number of rotations of the transmission rod. By adjusting the number of rotations of the transmission rod, the vertical movement amplitude of the lifting plate and the movement amplitude of the buffer block can be adjusted, making it convenient for staff to make adjustments according to the actual water pressure.

[0020] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0021] Please see Figures 1-9 This invention provides a technical solution: an ultra-high pressure solenoid valve based on underwater detection, including a connecting pipe 1, an electrically controlled valve stem 2 installed above the connecting pipe 1, a piston plate 3 connected to the bottom end of the electrically controlled valve stem 2, and the piston plate 3 slidably connected to the connecting pipe 1, a sealing block 4 connected to the bottom of the piston plate 3, a conical groove opened on the inner side of the piston plate 3, and a buffer block 6 slidably connected to the conical groove, a transmission rod 5 rotatably connected to the piston plate 3, and the transmission rod 5 threadedly connected to the buffer block 6, the transmission rod 5 having a rotating groove composed of curves and straight lines, a flow frame 7 connected to the inner wall of the connecting pipe 1, and the flow frame 7 connected to the conical groove of the piston plate 3 through a corrugated pipe, a buffer frame 8 connected to the outer side of the connecting pipe 1, and the flow frame 7 connected to the buffer frame 8, and the buffer frame 8 connected to the connecting pipe 1 through a flexible hose, the inner side of the buffer frame 8... A buffer plate 9 is slidably connected, and a fixed plate 10 is connected to the inner wall of the connecting pipe 1. An adjusting rod 11 is rotatably connected to the fixed plate 10, and a transmission plate 12 is threadedly connected to the adjusting rod 11. The transmission plate 12 has a hole, and a semi-circular protrusion is provided in the hole. The semi-circular protrusion is located in the rotation groove of the transmission rod 5. When the piston plate 3 moves downward to close the connecting pipe 1, it drives the transmission rod 5 to rotate. The rotation of the transmission rod 5 drives the buffer block 6 to move upward and gradually open the conical groove at the bottom of the sealing block 4. The impacting water flow can enter the inner side of the buffer frame 8 through the gradually opening conical groove, thereby reducing the water flow pressure when the sealing block 4 is closed and reducing the occurrence of damage to the sealing block 4 and piston plate 3 due to impact force. Furthermore, the buffer solution stored inside the buffer frame 8 will flow back to the inlet end of the connecting pipe 1 under the action of the spring. Reinforcing component 13 is disposed inside the connecting pipe 1, and adjusting component 14 is disposed above the fixing plate 10.

[0022] In one embodiment of the present invention, the reinforcing component 13 includes a cross rod 131 slidably connected above the transmission rod 5, a threaded rod 133 connected to the top of the cross rod 131, an L-shaped rotating plate 132 connected above the fixing plate 10, and the L-shaped rotating plate 132 rotatably connected to the threaded rod 133. The threaded rod 133 is threadedly connected to a lifting plate 134, a compression ring 135 is connected above the lifting plate 134, a sealing frame 136 is connected to the bottom of the piston plate 3, a rubber pad 137 is provided inside the sealing frame 136, and the rubber pad 137 is in contact with the compression ring 135. The transmission rod 5 rotates, causing the threaded rod 133 to rotate. The rotation of the threaded rod 133 causes the lifting plate 134 to move vertically. The movement of the lifting plate 134 causes the compression ring 135 to move. The compression ring 135 moves upward to compress the rubber pad 137 so that it fits tightly against the outside of the valve stem of the electric control valve 2. The valve stem is reinforced by the rubber pad 137, reducing the amplitude of the valve stem shaking due to water flow. In one embodiment of the present invention, the adjustment component 14 includes a waterproof motor 141 connected to the outside of a connecting pipe 1. A rotating rod 142 is connected to the output end of the waterproof motor 141, and the rotating rod 142 is rotatably connected to the connecting pipe 1. The rotating rod 142 is connected to the adjustment rod 11 through a bevel gear set. By starting the waterproof motor 141, the rotating rod 142 can be driven to rotate. The rotation of the rotating rod 142 adjusts the height of the transmission plate 12, thereby adjusting the number of rotations of the transmission rod 5. By adjusting the number of rotations of the transmission rod 5, the vertical movement amplitude of the lifting plate 134 and the movement amplitude of the buffer block 6 can be adjusted, which is convenient for the staff to adjust according to the actual water pressure. In one embodiment of the present invention, a sliding rod is connected to the inner side of the piston plate 3. The sliding rod is slidably connected to the buffer block 6. The buffer block 6 is limited by the sliding rod, thereby improving the stability of the buffer block 6 during vertical movement. As one embodiment of the present invention, a one-way valve is connected above the water inlet end of the connecting pipe 1. The one-way valve is connected to the buffer frame 8 through a hose. A one-way valve is provided at the connection between the flow frame 7 and the buffer frame 8. By providing a one-way valve, water flow from the water inlet end of the connecting pipe 1 is prevented from entering the inner side of the buffer frame 8. As one embodiment of the present invention, a spring is connected above the buffer plate 9, and the top of the spring is connected to the top of the inner side of the buffer plate 9. The spring can push the liquid inside the buffer frame 8 to re-enter the water inlet of the piston plate 3. As one embodiment of the present invention, two sets of buffer blocks 6 are provided. The bottom surface of both sets of buffer blocks 6 is sloping. By providing two sets of buffer blocks 6, the liquid input into the buffer frame 8 can be better buffered. In one embodiment of the present invention, a guide rod is connected above the flow frame 7, and the guide rod is slidably connected to the lifting plate 134. The guide rod can limit the lifting plate 134 and reduce the occurrence of vertical displacement of the lifting plate 134. In one embodiment of the present invention, a limiting rod is connected above the transmission plate 12, and the limiting rod is slidably connected to the fixed plate 10. By setting the limiting rod, the transmission plate 12 can be limited, thereby improving the stability of the transmission plate 12 during vertical movement.

[0023] Working principle: First, when the solenoid valve stem 2 is activated to close the connecting pipe 1, the solenoid valve stem 2 generates magnetic force, pushing the valve stem downward. The movement of the valve stem drives the piston plate 3 downward, which in turn drives the sealing block 4 to gradually fit against the inner side of the connecting pipe 1 for sealing. Since the sealing block 4 is rotatably connected to the transmission rod 5, the downward movement of the sealing block 4 drives the transmission rod 5 downward. Because the semi-circular protrusion of the transmission plate 12 is located in the rotating groove of the transmission rod 5, the downward movement of the transmission rod 5 will cause the semi-circular protrusion and the rotating groove to overlap. Under the influence of the transmission rod 5, the transmission rod 5 rotates. Since the transmission rod 5 is threadedly connected to the buffer block 6, the rotation of the transmission rod 5 drives the buffer block 6 to move upward, causing the opening of the conical groove of the sealing block 4 to gradually increase in size to meet the gradually increasing water pressure. Since the flow frame 7 is connected to the conical groove of the sealing block 4 through the bellows, some water will enter the flow frame 7 through the conical groove of the sealing block 4 and then enter the buffer frame 8 through the flow frame 7. By storing some of the water, the liquid impact force received by the sealing block 4 when it closes is reduced. Secondly, since the transmission rod 5 is slidably connected to the cross rod 131, the rotation of the transmission rod 5 will also drive the cross rod 131 to rotate. The rotation of the cross rod 131 will drive the threaded rod 133 to rotate. Since the threaded rod 133 is threadedly connected to the lifting plate 134 and the lifting plate 134 is slidably connected to the guide rod, the rotation of the threaded rod 133 will drive the lifting plate 134 to move upward. The upward movement of the lifting plate 134 will drive the compression ring 135 to move upward. The upward movement of the compression ring 135 will push the rubber pad 137 inside the sealing frame 136 to compress, which will increase the contact pressure between the rubber pad 137 and the valve stem, thereby gradually reinforcing the valve stem and reducing the valve stem from shaking due to water flow. Then, after the water flows into the inside of the buffer frame 8, it gradually pushes the buffer plate 9 upward. The upward movement of the buffer plate 9 causes the spring to deform. When the connecting pipe 1 is reopened, the upward movement of the valve stem will drive the buffer block 6 to move downward and close. Since the water pressure at the inlet of the buffer frame 8 is reduced, the spring will gradually recover its deformation and push to apply pressure to the liquid in the inner tank of the buffer frame 8. The liquid in the inner tank of the buffer frame 8 will enter the inlet end of the piston plate 3 through the hose, which facilitates the storage and buffering of subsequent liquids. Finally, when it is necessary to buffer the high-pressure water flow, the waterproof motor 141 is started. The operation of the waterproof motor 141 drives the rotating rod 142 to rotate. Since the rotating rod 142 is connected to the adjusting rod 11 through a bevel gear set, the rotation of the rotating rod 142 will drive the adjusting rod 11 to rotate. Since the adjusting rod 11 is threadedly connected to the transmission plate 12 and the transmission plate 12 is slidably connected to the limit rod, the rotation of the adjusting rod 11 will drive the transmission plate 12 to move downward, adjusting the initial height of the transmission plate 12. During the downward movement of the transmission rod 5, the curved position of the rotating groove can contact the semi-circular protrusion of the transmission plate 12 earlier, causing the transmission rod 5 to rotate. This increases the number of rotations of the transmission rod 5, thereby increasing the upward movement amplitude of the buffer block 6 and the upward movement amplitude of the squeezing ring 135. The upward movement amplitude of the buffer block 6 allows the water flow to enter the buffer frame 8 more quickly, improving the buffering capacity. The increased upward movement amplitude of the squeezing ring 135 increases the pressure of the rubber pad 137 on the valve stem, further improving the stability of the valve stem.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
