Its core function is to meet the equipment's demand for high-flow, low-pulsation fluid supply when switching operating conditions through efficient flow regulation, while also taking into account performance such as shock absorption, leakage prevention, and response speed.

[0003] Regarding the aforementioned technologies, the existing liquid supply valves have the following drawbacks: in high-pressure, high-flow-rate liquid supply scenarios, the fluid is prone to strong pulsations due to turbulence and sudden on / off cycles when flowing through the valve body, which can cause valve body resonance, leading to pipeline loosening and fatigue fracture of connecting parts. Therefore, this utility model provides a push-to-flow rapid liquid supply valve. Utility Model Content

[0009] Preferably, a fixing cylinder is provided on the outer side of the lifting rod, an upper flange is fixedly connected to the outer side of the fixing cylinder, and a lower flange adapted to the upper flange is provided on the outer side of the valve body.

[0023] Example 1: Reference Figure 1-4The push-to-feed quick-release valve shown includes a valve body 1, which serves as the overall mounting base, providing support and protection for the internal components. A buffer chamber 23 is provided on its inner side, which temporarily stores fluid and mitigates fluid pressure fluctuations. One end of the valve body 1 has a first valve port 16 communicating with the buffer chamber 23, serving as the channel for fluid to enter the buffer chamber 23. The other end of the valve body 1 has a second valve port 17 communicating with the buffer chamber 23, serving as the channel for fluid to flow out of the buffer chamber 23. A sealing plate 24 is fixedly connected to the inner wall of the buffer chamber 23, serving to separate the internal space of the buffer chamber 23 and enhance the sealing performance. A lifting rod 6 is provided through the inner side of the sealing plate 24. The lifting rod 6 can drive related components to move up and down to control the valve opening and closing state. One end of the lifting rod 6 is fixedly connected to a pressure block 18, which can transmit the force of the lifting rod 6 and exert pressure on the valve disc 19. The bottom end of the pressure block 18 is provided with a valve disc 19 that matches the first valve hole 16. The valve disc 19 opens or closes the first valve hole 16 by cooperating with the first valve hole 16. A buffer flow component is provided on the outer side of the pressure block 18. The buffer flow component can reduce the impact force when the fluid passes through and stabilize the flow rate. Multiple flow stabilizing components are provided in both the first valve hole 16 and the second valve hole 17. The flow stabilizing components can make the fluid flow... To ensure smoother movement and reduce turbulence, a connecting rod 22 is fixedly connected to the outer side of the pressure block 18. The connecting rod 22 transmits the movement of the pressure block 18 to the auxiliary valve disc 13. One end of the connecting rod 22 is fixedly connected to the auxiliary valve disc 13, which controls the opening and closing of the small flow channel 2. A small flow channel 2, which communicates with the first valve hole 16, is opened on the inner wall side of the buffer chamber 23. The small flow channel 2 provides an auxiliary flow path when the main channel flow is small. The auxiliary valve disc 13 is adapted to the small flow channel 2 to ensure the sealing effect of the small flow channel 2. The auxiliary valve disc 13 is slidably connected to the top position of the small flow channel 2, allowing the auxiliary valve disc 13 to move flexibly to open or close. Close the small flow channel 2; multiple adjacent flow stabilizing components are staggered to guide and stabilize the fluid from different angles. The flow stabilizing components include a fixing ring 20 fixedly connected to the inner wall of the first valve port 16 and the second valve port 17. The fixing ring 20 provides a mounting carrier for the grid plates 21 and enhances the structural stability of the flow stabilizing components. Multiple grid plates 21 are fixedly connected to the inner wall of the fixing ring 20. The grid plates 21 can divide the fluid and guide its orderly flow. The thickness of the grid plates 21 is gradually set, with the end closer to the inlet being thicker and the end farther from the inlet being thinner. This can reduce the resistance at the fluid inlet while ensuring the guiding effect at the outlet, further improving the flow stabilizing performance. Push-to-flow quick liquid supply valve, including valve body 1, serves as the basic component of the entire valve, providing structural support and installation space for internal components. A buffer chamber 23 is provided on the inner side of the valve body 1. The buffer chamber 23 is used to store liquid and buffer fluid pressure fluctuations, reducing the impact on the internal components of the valve.One end of the valve body 1 is provided with a first valve hole 16 communicating with the buffer chamber 23, which serves as the main channel for liquid to enter the valve. The other end of the valve body 1 is provided with a second valve hole 17 communicating with the buffer chamber 23, which serves as the main channel for liquid to exit the valve. A sealing plate 24 is fixedly connected to the inner wall of the buffer chamber 23, which is used to separate different areas of the buffer chamber 23 to prevent liquid leakage. A lifting rod 6 is provided through the inner side of the sealing plate 24, which can move up and down within the sealing plate 24 to transmit operating force. A pressure block 18 is fixedly connected to one end of the lifting rod 6, which moves with the lifting rod 6. A valve disc 19 adapted to the first valve hole 16 is provided at the bottom of the pressure block 18, which is used to control the opening and closing of the first valve hole 16 to regulate the liquid flow. A buffer flow assembly is provided on the outer side of the pressure block 18, which is used to buffer the impact force of the liquid flow and reduce pressure fluctuations. Multiple flow stabilizing components are installed in both the first valve port 16 and the second valve port 17. These components stabilize the liquid flow and reduce turbulence and eddies. A connecting rod 22 is fixedly connected to the outside of the pressure block 18. The connecting rod 22 connects the pressure block 18 and the auxiliary valve disc 13 to transmit motion. One end of the connecting rod 22 is fixedly connected to the auxiliary valve disc 13, which seals the small flow channel 2 and controls the small flow of liquid. A small flow channel 2, which communicates with the first valve port 16, is opened on the inner wall of the buffer chamber 23. The small flow channel 2 provides an additional liquid flow path when the main channel flow is low. The auxiliary valve disc 13 is adapted to the small flow channel 2 and is slidably connected to the top of the small flow channel 2 to ensure that the auxiliary valve disc 13 can accurately control the opening and closing of the small flow channel 2. Multiple adjacent flow stabilizing components are arranged in an alternating manner, which enhances the stabilization effect on the liquid flow. The flow stabilizing assembly includes a fixing ring 20 fixedly connected to the inner wall side of the first valve orifice 16 and the second valve orifice 17. The fixing ring 20 is used to fix the grid plates 21 and provide structural support. Multiple grid plates 21 are fixedly connected to the inner wall side of the fixing ring 20. The grid plates 21 are used to divide the liquid flow, making the liquid flow more uniform. The thickness of the grid plates 21 is gradually varied, with the end closer to the inlet being thicker and the end farther from the inlet being thinner. This gradual thickness design guides the liquid to flow smoothly and reduces energy loss.

[0024] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a pair of guide rods 15 are fixedly connected to the outer side of the lifting rod 6. The guide rods 15 can limit the movement direction of the lifting rod 6 and prevent it from deviating. A guide groove 14 adapted to the guide rod 15 is opened on the outer side of the sealing plate 24. The guide groove 14 provides a movement path for the guide rod 15 and ensures that the guiding function is stable. A fixed cylinder 5 is provided on the outer side of the lifting rod 6. The fixed cylinder 5 can provide installation space for internal components and play a protective role. An upper flange 3 is fixedly connected to the outer side of the fixed cylinder 5. The upper flange 3 can cooperate with the lower flange 4 to achieve a fixed connection. A lower flange 4 adapted to the upper flange 3 is provided on the outer side of the valve body 1. The combination of the lower flange 4 and the upper flange 3 can enhance the stability of the connection and ensure the stability of the overall structure. A sealing assembly is provided inside the fixed cylinder 5. The sealing assembly can enhance the sealing between the fixed cylinder 5 and the lifting rod 6. The sealing assembly includes sealing gaskets 1 arranged sequentially on the inner wall side of the fixed cylinder 5. 2. The elastic sealing compensation collar 11 and sealing gasket 12 can initially block fluid leakage. The elastic sealing compensation collar 11 can further improve the sealing effect by compensating for the sealing gap through its own elasticity. Multiple fixing rods 7 are fixedly connected to the outside of the fixed cylinder 5. The fixing rods 7 can connect the positioning ring 9 to the fixed cylinder 5 as a whole to ensure that the position of the positioning ring 9 is fixed. The positioning ring 9 is fixedly connected to one end of the fixing rod 7. The positioning ring 9 can play a positioning and support role for the threaded rod 8. The inner wall of the positioning ring 9 is provided with internal threads. The internal threads can cooperate with the external threads of the threaded rod 8 to realize thread transmission. One end of the lifting rod 6 is rotatably connected to the threaded rod 8 that is compatible with the positioning ring 9. When the threaded rod 8 rotates, it can drive the lifting rod 6 to move up and down. One end of the threaded rod 8 is fixedly connected to the handle 10. The handle 10 makes it easy for the operator to rotate the threaded rod 8, saving physical strength. The outer side of the handle 10 is provided with a rubber layer. The rubber layer can increase the friction between the hand and the handle 10, prevent slippage during operation, and improve the grip comfort.

[0025] The working principle of this utility model is as follows: Driving the handle 10 drives the threaded rod 8 to rotate, which in turn drives the lifting rod 6, the pressure block 18, and the valve disc 19 to move upward. The pressure block 18 drives the auxiliary valve disc 13 to move upward through the connecting rod 22, thereby releasing the blockage of the small flow channel 2 and preventing system pressure fluctuations caused by instantaneous large flow impacts. The lifting rod 6 continues to move, driving the pressure block 18 and the valve disc 19 to move, thereby releasing the blockage of the first valve hole 16. The flow stabilizing component is set up with staggered grid plates, which divide the high-speed liquid flow into multiple fine streams and reduce flow velocity pulsation.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
