Technical field

Background technique

Copper valves are devices used to control the direction, pressure, and flow of fluids in fluid systems. Valves are devices that allow the media (liquid, gas, powder) in pipes and equipment to flow or stop and control their flow. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are control components in pipeline fluid transportation systems. They are used to change The passage section and medium flow direction have the functions of diversion, cutoff, throttling, check, diverting or overflow pressure relief.

Existing copper valves are forced to shut off manually and cannot automatically adjust the flow rate through the valve. When the flow rate is too fast, it means that the water pipeline is broken and leaking, and it is easy to waste water resources.

During operation, when the water flow rate continues to be at the maximum, the push rod 502 is pushed inward under the action of the lever 415. The push rod 502 is placed outside the outer wall of the first piston rod 2 and compresses the second spring 501 inward. The push rod 502 is in the movable groove. The inside of 503 slides inward, and the push rod 502 pushes the pressure plate 506 inward and compresses the third spring 505. The pressure plate 506 drives the valve plate 507 to move inside the gas tank 504. At this time, the valve plate 507 cannot block the nozzle 508, and the gas The compressed gas inside the tank 504 enters the inside of the channel 509 through the nozzle 508, thereby inflating the inside of the channel 509 and pushing the second piston block 510.

Control and save water resources to prevent waste of water resources.

Working principle: In the initial state, the swing rod 409 is in a vertical and intermediate position under the action of the balance spring 408. Under the action of the swing rod 409, the stop block 410 is at the outermost position of the first movable opening 407, and the first spring 412 is at the outermost position. The first movable port 407 is in an extended state, the lever 415 is in a horizontal state under the action of the movable plate 413, so that the first piston rod 2 drives the first piston block 3 to the outermost position, and the second spring 501 is in an extended state. The push rod 502 is at the outermost position. Under the stretching action of the third spring 505, the valve plate 507 is driven by the pressure plate 506 to block the nozzle 508. At the same time, under the stretching action of the fourth spring 516, the flow stop plate 517 is driven at the outermost position. When the flow is stopped, the push rod 502 is at the outermost position. Under the action of the plate 517, the inclined block 512 is pushed to the innermost side of the first slide groove 513. At the same time, the inclined block 512 drives the second piston block 510 to the innermost side of the channel 509 through the second piston rod 511.

During the working process, the water source flows into the interior of the copper valve body 1, causing water resistance between the water source and the fan blade 405, and then the fan blade 405 rotates under the action of the water source. At normal flow speed, the water resistance against the fan blade 405 is small. The water resistance is less than the elastic force of the balance spring 408. The swing rod 409 is stabilized in the middle position of the slide 406 under the action of the balance spring 408, ensuring the normal flow rate of water resources, preventing the flow of water from being reduced under normal flow rates, and improving the practicality of the equipment. property, but when the flow rate of the water flow is too high, the water resistance generated by the water flow and the fan blade 405 is greater than the elastic force of the balance spring 408, which in turn causes the fan blade 405 to rotate around the rotating shaft 404 as the axis. The rotating shaft 404 drives the swing rod in the middle of the bearing 403 409 rotates, the swing rod 409 drives the back block 410 to rotate inside the slide 406. At the same time, the back block 410 compresses the balance spring 408 on one side and stretches the balance spring 408 on the other side, so that the balance spring 408 can stabilize the back block 410. Rotate so that the stop block 410 can detect the flow rate of water resources to the maximum extent. Because the stop block 410 rotates to one side inside the slide 406, the stop block 410 cannot contact the inside of the movable plate 413. The movable plate 413 is in the Under the action of a spring 412, the inside of the first movable port 407 moves toward the inside of the slide 406. At the same time, the outer end of the movable plate 413 drives the lever 415 to rotate downward with the support plate 414 as the axis, ensuring that short-distance movement can be long. The distance transmission ensures the power of the device to control water resources. The inner side of the lever 415 drives the first piston rod 2 to converge inward. At the same time, the lever 415 only indirectly pushes the push rod 502 to move inward and does not trigger the flow stop. Mechanism 5 works, and the first piston rod 2 drives the first piston block 3 to move toward the middle. The first piston block 3 will not block the flow of water through the copper valve body 1 no matter how large the water flow is, thus effectively ensuring The water flow is controlled under the action of the water flow velocity. At the same time, the water flow itself can cooperate with the first piston block 3 to make the water flow tend to be stable inside the copper valve body 1, preventing the problem of the water flow velocity being too fast. It improves the equipment's control over water resources and ensures the use of water resources.

When the water flow rate is at the maximum for a long time, it means that there is damage in the water pipeline. Then under the action of the lever 415, the push rod 502 will be at the innermost position for a long time, and the flow limiting mechanism 4 will drive the flow stopping mechanism 5 through the operation of the flow limiting mechanism 4. The push rod 502 is placed outside the outer wall of the first piston rod 2 and compresses the second spring 501 inward for a long time. The push rod 502 is in the movable groove 503. The inside slides inward, and the push rod 502 pushes the pressure plate 506 inward and compresses the third spring 505. The pressure plate 506 drives the valve plate 507 to move inside the gas tank 504. At this time, the valve plate 507 cannot block the nozzle 508 and is compressed. The gas is transmitted to ensure the delay of the transmission of the equipment. The compressed gas inside the gas tank 504 enters the inside of the channel 509 through the nozzle 508. When the gas inside the channel 509 continues to grow, the air inside the channel 509 is inflated to push the second piston. Block 510, the second piston block 510 pushes the second piston rod 511 outward inside the channel 509, and the second piston rod 511 drives the inclined block 512 to slide outward inside the first slide groove 513. Under the action of the inclined block 512 The flow stop plate 517 is converged toward the middle of the second chute 519 inside the second movable port 514 and compresses the fourth spring 516. The flow stop plate 517 drives the flow stop plate 518 to converge, which can block the water source flow such as the copper valve body 1. Internally, it prevents the loss of water resources caused by excessive flow speed, and at the same time ensures the control of water resources by the equipment, saves water resources and prevents the waste of water resources.
