Description

Technical Field

[0001] The utility model relates to the technical field of water flow control, in particular to a fluid one-way valve. Background Art

[0002] One-way valves are used in pipeline containers to limit pressure or flow direction. General one-way valves are composed of pipelines, sealing balls, springs and conical structures. When the pressure at one end of the pipeline is high, the ball at the conical hole is pushed open to allow the valve body to be conducted. When the reverse pressure is high, the ball seals the conical hole, prohibiting the fluid from passing through, thus completing one-way conduction. This traditional one-way valve generally cannot control the flow rate of the liquid.

[0003] The Chinese patent number "CN117814973A" discloses an anti-reflux biliary stent based on a Tesla valve, which includes: a biliary stent body; a fixing member, which is arranged inside the biliary stent body; a valve channel, which is arranged on the fixing member, and the two ends of the valve channel are respectively connected to the inner cavity of the biliary stent body at the two ends of the fixing member; a sliding member, which is arranged inside the biliary stent body and is slidably connected to the fixing member; and a valve body, which is arranged on the sliding member, and the valve body is slidably arranged in the valve channel, and is used to switch the unidirectional or bidirectional opening state of the valve channel. This application uses the unique structural design of the Tesla valve to ensure smooth drainage in the bile discharge direction, while preventing intestinal reflux from passing through, thereby reducing the occurrence of reflux cholangitis and improving the quality of life of patients.

[0004] The Tesla valve structure design of the device can be used for water flow control, but it cannot control the flow rate and flow rate of the water flow. Therefore, an improvement is proposed to control the flow rate and flow rate of the water flow by controlling the number of valve bodies of the Tesla valve. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A fluid one-way valve is designed, comprising a valve body plate, a valve channel is provided inside the valve body plate, a plurality of lifting grooves are provided inside the valve channel, a valve body assembly is slid up and down inside the lifting groove, a lower valve plate is provided below the valve body plate, and a driving assembly for lifting the valve body assembly is provided inside the lower valve plate;

[0008] The driving assembly includes two sets of sliding grooves opened inside the lower valve plate, and the sliding grooves are slidably connected with a lifting plate inside. The length of the lifting plate is set to half of the sliding groove, and the upper end surface of the lifting plate slides against the lower end surface of the valve body assembly.

[0009] The valve body assembly includes a blocking valve body slidably connected to the inside of the lifting groove, the lower end surface of the blocking valve body is fixedly connected to a fixing plate, one side end surface of the fixing plate is fixedly connected to a lifting block, and the upper end surface of the lifting plate slides against the lower end surface of the lifting block.

[0010] A lifting slope is provided on one side of the lifting plate, and the lifting plate slides and abuts against the lifting block from one side of the lifting slope.

[0011] The interior of the sliding groove is rotatably connected with a screw rod penetrating the lifting plate, and the outer end surface of the lower valve plate is fixedly mounted with a motor, and the output shaft of the motor is transmission-connected with the screw rod.

[0012] The lower end surface of the valve body plate is fixedly connected with a support bar, the lower end surface of the support bar movably abuts against the lower valve plate, and the height of the support bar is equal to the distance of the up and down movement of the valve body assembly.

[0013] An upper valve plate sealingly covering the valve channel is arranged above the valve body plate, and sealing fixing members are fixedly connected to the front and rear sides of the valve body plate by bolts, and the sealing fixing members fix the upper valve plate, the lower valve plate and the valve body plate so that they cannot be separated.

[0014] Preferably, a plurality of limit grooves are provided inside the valve body plate, a plurality of limit rods are fixedly connected to the lower end surface of the upper valve plate, and the limit rods are movably inserted into the limit grooves.

[0015] Preferably, a valve body groove cooperating with the valve body assembly is provided inside the upper valve plate, and the top of the valve body assembly is movably plugged into the inside of the valve body groove.

Through the cooperation of the valve body assembly and the valve body groove, the strength of the valve body assembly can be strengthened to avoid it from being deflected by the impact of water flow, thereby ensuring that the device can operate stably.

DETAILED DESCRIPTION

[0026] 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 of the embodiments.

[0027] Reference Figure 1-7 A fluid one-way valve comprises a valve body plate 3, a valve channel 301 is provided inside the valve body plate 3, a plurality of lifting grooves 303 are provided inside the valve channel 301, a valve body assembly is slid up and down inside the lifting grooves 303, a lower valve plate 2 is provided below the valve body plate 3, a driving assembly for lifting the valve body assembly is provided inside the lower valve plate 2;

[0028] The driving assembly includes two sets of sliding grooves 201 opened inside the lower valve plate 2. The sliding grooves 201 are slidably connected to the inside of the lifting plate 6. The length of the lifting plate 6 is set to half of the sliding groove 201. The upper end surface of the lifting plate 6 slides against the lower end surface of the valve body assembly. The valve body assembly is lifted by the lifting plate 6. By controlling the number of valve body assemblies that make up the Tesla valve, the flow rate and flow velocity of the one-way valve can be accurately controlled, which facilitates the use of the one-way valve.

[0029] The valve body assembly includes a blocking valve body 4 slidably connected to the inside of the lifting groove 303, the lower end face of the blocking valve body 4 is fixedly connected to a fixing plate 401, and one side end face of the fixing plate 401 is fixedly connected to a lifting block 402, and the upper end face of the lifting plate 6 slides against the lower end face of the lifting block 402. The blocking valve body 4 can be fixed by the fixing plate 401, so that the blocking valve body 4 can be conveniently controlled to move up and down, and the lifting block 402 is arranged on a single side of the valve body assembly. Through two groups of symmetrical lifting plates 6, the valve body assemblies on different sides of the lifting block 402 can be controlled respectively. At the same time, because the lifting block 402 is not arranged on the other side of the valve body assembly, the valve body assembly is effectively prevented from being affected by the lifting plate 6.

[0030] A lifting slope is provided on one side of the lifting plate 6, and the lifting plate 6 slides against the lifting block 402 from one side of the lifting slope. By providing the lifting slope, the lifting plate 6 can lift the valve body assembly well to avoid collision.

[0031] The internal rotation of the sliding groove 201 is connected with a screw rod 5 that passes through the lifting plate 6. The outer end surface of the lower valve plate 2 is fixedly installed with a motor 501. The output shaft of the motor 501 is transmission-connected to the screw rod 5. The screw rod 5 is driven to rotate by the motor 501, which can drive the lifting plate 6 to move.

[0032] The lower end surface of the valve body plate 3 is fixedly connected to a support bar 302, and the lower end surface of the support bar 302 movably abuts against the lower valve plate 2. The height of the support bar 302 is equal to the distance that the valve body assembly moves up and down. The valve body plate 3 can be supported by the support bar 302 to ensure space for the valve body assembly to move up and down. The valve body assembly can be completely separated from the valve channel 301 to prevent the valve body assembly from affecting the flowability of the valve channel 301.

[0033] An upper valve plate 1 sealingly covering the valve channel 301 is arranged above the valve body plate 3. The front and rear sides of the valve body plate 3 are fixedly connected with sealing fixing parts 7 by means of bolts. The sealing fixing parts 7 fix the upper valve plate 1, the lower valve plate 2 and the valve body plate 3 so that they cannot be separated. Through the cooperation of the sealing fixing parts 7, the upper valve plate 1, the lower valve plate 2 and the valve body plate 3 can be fixed to make them tightly sealed to avoid leakage.

[0034] A plurality of limit grooves 304 are provided inside the valve body plate 3, and a plurality of limit rods 102 are fixedly connected to the lower end surface of the upper valve plate 1. The limit rods 102 are movably inserted into the limit grooves 304. Through the cooperation between the limit rods 102 and the limit grooves 304, the upper valve plate 1 and the valve body plate 3 can be fixed to ensure the accuracy of their fixation.

[0035] A valve body groove 101 that cooperates with the valve body assembly is opened inside the upper valve plate 1. The top of the valve body assembly is movably inserted into the inside of the valve body groove 101. Through the cooperation between the valve body assembly and the valve body groove 101, the strength of the valve body assembly can be enhanced to prevent it from being deflected by the impact of water flow, thereby ensuring that the device can operate stably.

[0036] Working mode: When working, the motor 501 will drive the screw rod 5 to rotate. At this time, the lifting plate 6 will slide along the sliding groove 201. The lifting plate 6 will gradually contact the lifting block 402 of the valve body assembly from one side of the lifting slope, and the lifting block 402 is arranged on a single side of the valve body assembly. In this way, two groups of symmetrical lifting plates 6 are used to control the valve body assemblies on different sides of the lifting block 402 respectively. At the same time, because the lifting block 402 is not arranged on the other side of the valve body assembly, the valve body assembly is effectively prevented from being affected by the lifting plate 6. In this way, the valve body assembly moves upward to the inside of the valve channel 301 to form a Tesla valve. The device can accurately control the flow rate and flow velocity of the one-way valve by controlling the number of valve bodies that make up the Tesla valve, thereby facilitating the use of the one-way valve. It has a simple structure and a good use effect.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
