[0002] Marine valves are valves designed to meet the environmental conditions of ships, and are mainly used to control the pressure, flow and flow direction of fluids in ship pipelines. Valves are control devices for fluid pipelines, and their basic functions are to connect or cut off the flow of pipeline media, change the flow of media, change the flow direction of media, adjust the pressure and flow of media, and protect the normal operation of pipeline equipment.

[0003] A Chinese patent with publication number CN216666590U discloses an automatic check valve, which is provided with an anti-backflow mechanism and can cause water to flow through the valve housing through water pressure. After the water pressure disappears, the inside of the valve housing can be automatically sealed through the elastic action of the spring, thereby achieving the anti-backflow effect; by providing a threaded groove, the valve housing can be conveniently installed on the pipeline, and the role of the sealing ring and the second sealing gasket is cooperated to further improve the sealing effect of the threaded groove and the pipeline after connection.

[0004] In the current prior art, welding or screw connection is usually used to connect the valves, which is extremely time-consuming and labor-intensive when disassembling and assembling the valves.

[0005] To this end, the present invention provides a marine valve. Summary of the invention

[0008] By placing the valve body on the fixed valve unit, the fixed valve unit fixes the valve body, and then the cover plate is placed on the round table, and the cover plate is rotated to connect the two through the tight fitting component between the cover plate and the round table. After the connection is completed, a complete valve is formed at this time. When disassembling, the opposite is true, which facilitates the assembly and disassembly of the valve. When stopping the flow, the motor on the top of the round table drives the rotating shaft to rotate, and the rotating shaft drives the blocking fluid to rotate in the valve body at the same time. When the blocking fluid rotates to be level with the valve body, the motor stops rotating at this time, and the blocking fluid will block the flow of the liquid flowing in the valve body, thereby stopping the flow. Through the setting of the tight fitting component between the round table and the cover plate and the fixed valve unit at the bottom of the valve body, when the valve is damaged and replaced, it is only necessary to take out the valve body and then replace the completed valve body, which facilitates the replacement of the valve body.

[0009] Preferably, the output shaft of the motor is fixedly mounted with a plurality of rotating rods, and the bottoms of the plurality of rotating rods are fixedly mounted with shafts, and the plurality of shafts slide in contact with the inner wall of the flow-stop handle. When stopping the flow, the motor drives the shaft to rotate through the rotating rod, and while the shaft rotates, the shaft pushes the flow-stop handle to rotate, and while the flow-stop handle rotates, it drives the blocking fluid to rotate through the rotating shaft, thereby stopping the flow and controlling the flow of the liquid.

When the rotating shaft drives the sealing ring to rotate, the oil in the oil storage box can provide a certain lubrication for the sealing ring when it rotates in the valve body, which can reduce the friction during rotation and facilitate the rotation of the rotating shaft.

When the round table rotates to a certain position, the push rod spring in the matrix box pushes the clamping rod to slide out. When the clamping rod slides out under the thrust, one end of the clamping rod will be stuck into the bayonet in the cover plate. At this time, the cover plate and the round table form a complete fixed state. When disassembling, just reverse the cover plate, eject the clamping rod from the bayonet, and then lift the round table down, which is convenient for connection and fixation. By fixing the cover plate and the round table, the two can form a complete valve body, which is convenient for assembly.

When the blocking body and the valve body are in the same horizontal line, the sealing ring on the blocking body is completely in contact with the inner wall of the valve body to seal and prevent blocking liquid and leakage. The handle is set to facilitate the operation of the cover plate.

[0013] Preferably, the valve fixing unit can be divided into a valve holding assembly and a fixing assembly.

During the sliding process, the gear rod on the fixing plate drives the other fixing plate to slide on the other end of the valve body through the rotating wheel. When one of the fixing plates contacts one side of the valve body, the other fixing plate will also be driven by it to contact the other side of the valve body.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 9 As shown, a marine valve according to an embodiment of the present invention comprises a valve body 1, a plugging body 7 is arranged inside the valve body 1, a rotating shaft 10 is fixedly installed on the top of the plugging body 7, a flow stop handle 26 is fixedly installed on the top of the rotating shaft 10, a group of screw holes 29 are fixedly opened at both ends of the valve body 1, a round platform 9 is fixedly installed on the top of the valve body 1, the rotating shaft 10 is rotatably connected to the inner wall of the round platform 9, a cover plate 8 is arranged on the top of the round platform 9, a motor 2 is fixedly installed on the top of the cover plate 8, a tightening component is arranged between the cover plate 8 and the round platform 9, the tightening component is used to connect the cover plate 8 and the round platform 9, and plays the role of tightly connecting the round platform 9 and the valve body 1, and a fixed valve unit is arranged at the bottom of the valve body 1, and the fixed valve unit is used to fix the valve to facilitate the removal of the valve and play the role of fixing the valve;

[0034] In the current prior art, when installing a valve, welding or screw connection is usually used for connection. This connection method is extremely time-consuming and labor-intensive when disassembling and assembling the valve.

[0035] By placing the valve body 1 on the fixed valve unit, the fixed valve unit fixes the valve body 1, and then the cover plate 8 is covered on the round table 9, and the cover plate 8 is rotated to connect the two through the tight fitting component between the cover plate 8 and the round table 9. After the connection is completed, a complete valve is formed at this time. When disassembling, the opposite is true, which facilitates the assembly and disassembly of the valve. When stopping the flow, the motor 2 on the top of the round table 9 drives the rotating shaft 10 to rotate. While the rotating shaft 10 rotates, it drives the blocking body 7 to rotate in the valve body 1. When the blocking body 7 rotates to be horizontal with the valve body 1, at this time, the motor 2 stops rotating, and the blocking body 7 will block the flow of the liquid flowing in the valve body 1, which plays a role in stopping the flow. Through the setting of the tight fitting component between the round table 9 and the cover plate 8 and the fixed valve unit at the bottom of the valve body 1, when the valve is damaged, it only needs to take out the valve body 1 and then replace the completed valve body 1, which facilitates the replacement of the valve body 1.

[0036] like Figures 1 to 7 As shown, the output shaft of the motor 2 is fixedly mounted with a plurality of rotating rods 25, the bottoms of the plurality of rotating rods 25 are fixedly mounted with shafts 27, and the plurality of shafts 27 are slidably fitted with the inner wall of the stop handle 26;

[0037] When stopping the flow, the motor 2 drives the shaft 27 to rotate through the rotating rod 25. When the shaft 27 rotates, the shaft 27 pushes the flow stop handle 26 to rotate. When the flow stop handle 26 rotates, it drives the blocking body 7 to rotate through the rotating shaft 10, thereby stopping the flow and playing a role in controlling the flow of liquid. It should be noted here that the shaft 27 at the bottom of the motor 2 passes through the flow stop handle 26, and the two are in a fit state.

[0038] like Figure 3 to Figure 4 As shown, an oil storage box 21 is fixedly installed in the middle of the inner wall of the truncated table 9, and a plurality of sealing rings 18 are fixedly installed at the bottom end of the rotating shaft 10, and oil grooves 19 are provided between the plurality of sealing rings 18 and the oil storage box 21;

[0039] When the shaft 10 is rotating, the oil in the oil storage box 21 flows to between the sealing ring 18 and the valve body 1 through the oil groove 19. When the shaft 10 drives the sealing ring 18 to rotate, the oil in the oil storage box 21 can provide a certain lubrication for the sealing ring 18 when it rotates in the valve body 1, thereby reducing the friction during rotation and facilitating the rotation of the shaft 10. The oil lubrication can also prevent the sealing ring 18 from sticking to the valve body 1 due to external factors.

[0040] like Figures 4 to 6As shown, the tightening assembly includes a rectangular box 23, and there are multiple rectangular boxes 23. The inner walls of the multiple rectangular boxes 23 are all slidably connected with a clamping rod 20. A push rod spring 22 is fixedly installed between the inner walls of the multiple rectangular boxes 23 and one side of the multiple clamping rods 20. One end of the multiple clamping rods 20 penetrates the rectangular box 23 and is slidably connected to the inner wall of the round table 9. The inner wall of the cover plate 8 is provided with multiple bayonet holes 24, and one end of the multiple clamping rods 20 is slidably connected to the inner walls of the multiple bayonet holes 24 respectively.

[0041] When connecting the cover plate 8 and the round table 9, the cover plate 8 is covered on the round table 9, and then the cover plate 8 is pressed down. When the cover plate 8 is pressed down, the clamping rod 20 is squeezed to move in the rectangular box 23. When the cover plate 8 is fully pressed in, the cover plate 8 is rotated to make it rotate on the round table 9. When the round table 9 is rotated to a certain position, the push rod spring 22 in the rectangular box 23 pushes the clamping rod 20 to slide out. When the clamping rod 20 slides out under the thrust, one end of the clamping rod 20 will be stuck in the bayonet 24 in the cover plate 8. At this time, the cover plate 8 and the round table 9 form a complete fixed state. When disassembling, just reverse the cover plate 8, discharge the clamping rod 20 from the bayonet 24, and then lift the round table 9 down, which facilitates the connection and fixation. By fixing the cover plate 8 and the round table 9, the two can form a complete valve body, which facilitates assembly.

[0042] like Figure 1 to Figure 2 As shown, a sealing ring 28 is fixedly installed on the outer edge of the blocking body 7, and the sealing ring 28 is slidably connected to the inner wall of the valve body 1, and a handle 6 is symmetrically fixedly installed on the outer wall of the cover plate 8;

[0043] When the blocking body 7 is blocking the flow, the sealing ring 28 on the outer edge of the blocking body 7 contacts and rotates with the inner wall of the valve body 1. When the blocking body 7 and the valve body 1 are at the same horizontal line, the sealing ring 28 on the blocking body 7 is completely in contact with the inner wall of the valve body 1 to seal and prevent liquid blocking and leakage. The setting of the handle 6 is to facilitate the operation of the cover plate 8.

[0044] like Figures 8 to 9 As shown, the valve fixing unit can be divided into a valve holding component and a fixing component. The valve holding component is used to clamp and fit the two sides of the valve to prevent the valve from shaking during operation, and plays the role of clamping the valve. The fixing component is used to fix the valve holding component after the valve holding component has clamped and fixed the valve, and plays the role of fixing the valve.

[0045] During assembly, the valve body 1 is placed on the valve holding assembly, and then the valve holding assembly clamps and fits the two sides of the valve body 1, and then the fixing assembly fixes the valve holding assembly, thereby fixing the valve body 1 on the valve holding assembly. The valve body 1 can be fixed in place through the mutual cooperation of the fixing assembly and the valve holding assembly. At the same time, through the cooperation of the two, valve bodies 1 of different specifications can be fixed, thereby adapting to valve bodies 1 of different specifications.

[0046] like Figures 8 to 9 As shown, the valve holding assembly includes a fixed valve disc 3, the inner wall of the fixed valve disc 3 is symmetrically provided with slide grooves 17, the inner walls of the two slide grooves 17 are slidably connected with fixed plates 11, the tops of the two fixed plates 11 are slidably connected with the two ends of the valve body 1, a valve bearing block 5 is fixedly installed in the middle of the top of the fixed valve disc 3, the top of the valve bearing block 5 is fitted with the bottom of the valve body 1, the inner sides of the two fixed plates 11 are symmetrically provided with gear rods 12, the inner wall of the round table 9 is symmetrically provided with two running wheels 13, and the teeth on the four gear rods 12 are respectively meshed with the teeth on the two running wheels 13 in pairs;

[0047] When fixing the valve, the valve body 1 is placed on the valve block 5, and the two ends of the valve body 1 are placed on the two fixing plates 11 respectively. After placement, push one fixing plate 11 to slide on one end of the valve body 1, and the bottom of the fixing plate 11 will slide in the slide groove 17 in the fixing valve disc 3. During the sliding process, the gear rod 12 on the fixing plate 11 drives the other fixing plate 11 to slide on the other end of the valve body 1 through the rotating wheel 13. When one of the fixing plates 11 contacts one side of the valve body 1, the other fixing plate 11 will also be driven by it to contact the other side of the valve body 1. The two sides of the valve body 1 are respectively fitted and clamped by the two fixing plates 11, so as to fix the valve body 1. When disassembling, the opposite is true. The two fixing plates 11 can be adjusted by sliding to adapt to valve bodies 1 of different specifications. The valve body 1 is fixed by placing it on the valve block 5, which facilitates the fixing and disassembly of the valve body 1.

[0048] like Figures 8 to 9 As shown, the inner wall of the valve block 5 is symmetrically fixed with sliding openings 30, and the four gear rods 12 are slidably connected to the inner walls of the four sliding openings 30 respectively;

[0049] When the fixed plate 11 moves, the fixed plate 11 pushes the gear rod 12 to move in the sliding opening 30 , thereby driving another fixed plate 11 to move. The setting of the sliding opening 30 provides a certain path for the gear rod 12 to slide.

[0050] like Figure 1 to Figure 2 As shown, the inner wall of the fixed valve disc 3 is symmetrically provided with screw holes 4, and there are two groups of screw holes 4;

[0051] The fixed valve disc 3 can be fixed on the shipboard through the screw hole 4. When installing the valve, it is only necessary to place the valve body 1 on the valve bearing block 5, which makes the installation easier.

[0052] like Figures 8 to 9 As shown, the fixing assembly includes a solid block 14, the solid block 14 is slidably connected to the inner wall of the solid valve disc 3, the solid block 14 is placed in the slide groove 17, the inner wall of the solid valve disc 3 is fixedly installed with a limited sliding rod 16, the inner wall of the solid block 14 is slidably connected to the outer wall of the limited sliding rod 16, a return spring 15 is arranged between the inner side of the solid block 14 and the inner wall of the solid valve disc 3, and the return spring 15 is placed outside the limited sliding rod 16;

[0053] When the fixed plate 11 slides in the slide groove 17, the fixed plate 11 squeezes the fixed block 14 to slide on the sliding limit rod 16. When the inner side of the fixed plate 11 contacts one side of the valve body 1, the fixed plate 11 stops moving. At this time, the solid block 14 at the position corresponding to the fixed plate 11 will be pushed out by the return spring 15, and then stuck into the fixed plate 11 for limiting and fixing, thereby fixing the valve body 1.

[0054] Working principle: by placing the valve body 1 on the fixed valve unit, the fixed valve unit fixes the valve body 1, and then the cover plate 8 is covered on the round table 9, and the cover plate 8 is rotated to connect the two through the tight fitting components between the cover plate 8 and the round table 9. After the connection is completed, a complete valve is formed at this time. When disassembling, it can be done in reverse, which facilitates the assembly and disassembly of the valve. When stopping the flow, the motor 2 on the top of the round table 9 drives the rotating shaft 10 to rotate. While the rotating shaft 10 rotates, it drives the blocking body 7 to rotate in the valve body 1. When the blocking body 7 rotates to be horizontal with the valve body 1, at this time, the motor 2 stops rotating, and the blocking body 7 will block the flow of the liquid flowing in the valve body 1, which plays a role in stopping the flow. Through the setting of the tight fitting components between the round table 9 and the cover plate 8 and the fixed valve unit at the bottom of the valve body 1, when the valve is damaged, when it is replaced, it only needs to take out the valve body 1, and then replace the completed valve body 1, which facilitates the replacement of the valve body 1.

[0055] When stopping the flow, the motor 2 drives the shaft 27 to rotate through the rotating rod 25. When the shaft 27 rotates, the shaft 27 pushes the flow-stopping handle 26 to rotate. When the flow-stopping handle 26 rotates, it drives the blocking body 7 to rotate through the rotating shaft 10, thereby stopping the flow and controlling the flow of the liquid. The shaft 27 at the bottom of the motor 2 passes through the flow-stopping handle 26, and the two are in a close fit state.

[0056] When the shaft 10 is rotating, the oil in the oil storage box 21 flows to between the sealing ring 18 and the valve body 1 through the oil groove 19. When the shaft 10 drives the sealing ring 18 to rotate, the oil in the oil storage box 21 can provide a certain lubricity for the sealing ring 18 when it rotates in the valve body 1, which can reduce the friction during rotation and facilitate the rotation of the shaft 10. The oil lubrication can also prevent the sealing ring 18 from sticking to the valve body 1 due to external factors.

[0057] When connecting the cover plate 8 and the round table 9, the cover plate 8 is covered on the round table 9, and then the cover plate 8 is pressed down. When the cover plate 8 is pressed down, the clamping rod 20 is squeezed to move in the rectangular box 23. When the cover plate 8 is fully pressed in, the cover plate 8 is rotated to rotate on the round table 9. When the round table 9 is rotated to a certain position, the push rod spring 22 in the rectangular box 23 pushes the clamping rod 20 to slide out. When the clamping rod 20 slides out under the thrust, one end of the clamping rod 20 will be stuck in the bayonet 24 in the cover plate 8. At this time, the cover plate 8 and the round table 9 form a complete fixed state. When disassembling, it is only necessary to reverse the cover plate 8, discharge the clamping rod 20 from the bayonet 24, and then lift the round table 9 down, which plays a role in facilitating connection and fixing. By fixing the cover plate 8 and the round table 9, the two can form a complete valve body, which plays a role in facilitating assembly.

[0058] When the blocking body 7 is blocking the flow, the sealing ring 28 on the outer edge of the blocking body 7 contacts and rotates with the inner wall of the valve body 1. When the blocking body 7 and the valve body 1 are at the same horizontal line, the sealing ring 28 on the blocking body 7 is completely in contact with the inner wall of the valve body 1 to seal and prevent the blocking liquid and leakage. The setting of the handle 6 is to facilitate the operation of the cover plate 8.

[0059] During assembly, the valve body 1 is placed on the valve holding assembly, and then the valve holding assembly clamps and fits the two sides of the valve body 1, and then the fixing assembly fixes the valve holding assembly, thereby fixing the valve body 1 on the valve holding assembly. The valve body 1 can be fixed in position through the cooperation of the fixing assembly and the valve holding assembly. At the same time, through the cooperation of the two, valve bodies 1 of different specifications can be fixed, so as to adapt to valve bodies 1 of different specifications.

[0060] When fixing the valve, the valve body 1 is placed on the valve bearing block 5, and the two ends of the valve body 1 are placed on the two fixing plates 11 respectively. After placement, push one fixing plate 11 to slide on one end of the valve body 1, and the bottom of the fixing plate 11 will slide in the slide groove 17 in the fixing valve disc 3. During the sliding process, the gear rod 12 on the fixing plate 11 drives the other fixing plate 11 to slide on the other end of the valve body 1 through the rotating wheel 13. When one of the fixing plates 11 contacts one side of the valve body 1, the other fixing plate 11 will also be driven by it to contact the other side of the valve body 1. The two sides of the valve body 1 are respectively fitted and clamped by the two fixing plates 11, so as to achieve the fixing of the valve body 1. When disassembling, it can be done vice versa. The two fixing plates 11 can be adjusted by sliding to adapt to valve bodies 1 of different specifications. The valve body 1 is fixed by placing it on the valve bearing block 5, which plays a role in facilitating the fixing and disassembly of the valve body 1.

[0061] When the fixed plate 11 moves, the fixed plate 11 pushes the gear rod 12 to move in the sliding opening 30, thereby driving another fixed plate 11 to move. The setting of the sliding opening 30 provides a certain path for the gear rod 12 to slide;

[0062] The fixed valve disc 3 can be fixed on the shipboard through the screw hole 4. When installing the valve, it is only necessary to place the valve body 1 on the valve block 5, which facilitates the installation.

[0063] When the fixed plate 11 slides in the slide groove 17, the fixed plate 11 squeezes the fixed block 14 to slide on the sliding limit rod 16. When the inner side of the fixed plate 11 contacts one side of the valve body 1, the fixed plate 11 stops moving. At this time, the solid block 14 at the position corresponding to the fixed plate 11 will be pushed out by the return spring 15, and then stuck into the fixed plate 11 for limiting and fixing, thereby fixing the valve body 1.
