Description

Technical Field

[0001] The invention relates to the technical field of valve equipment, in particular to a valve system capable of rapid opening and closing. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. 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. However, due to long-term use of existing valves, when the valve is opened, a gap will appear between the screw rod controlling the valve and the center line of the valve, causing liquid or gas leakage, resulting in poor sealing. At the same time, there are problems with the low practicality of existing valves and inconvenience in operation.

[0003] In the prior art, the opening or closing state of the valve is generally achieved by rotating a hand wheel, which makes it extremely inconvenient to close or open the valve and cannot be opened or closed quickly. Summary of the invention

[0005] To achieve the above purpose, the following technical solution is adopted: a valve system capable of rapid opening and closing comprises a housing, a fluid channel is arranged in the housing along the length direction, a slide groove is symmetrically arranged in the housing at the lower end of the fluid channel, a locking block is slidably connected in the slide groove, a first spring is arranged between the locking block and the bottom of the slide groove, and an upper locking rod and a lower locking rod are respectively connected to the upper and lower ends of the two locking blocks that are close to each other.

[0006] The housing is provided with valve slots symmetrically in the vertical direction, a matching valve plate is slidably connected to the valve slot, the upper ends of the two valve plates extend to the outside of the housing and are commonly connected to an upper pressure plate, the valve plate extends through a fluid channel to the inside of the valve slot and is connected to a second spring, the other end of the second spring is connected to the bottom of the valve slot, a locking hole is provided on the valve plate, a first through hole connected to the valve slot is provided on the upper end of one side close to the two slide slots, the upper locking rod passes through the first through hole and is clamped in the locking hole, and a valve port matching the fluid channel is provided on the valve plate.

[0007] The shell is provided with a chamber, and a second through hole connected to the chamber is provided at the lower end of the side close to the two slide grooves, and a guide hole connected to the outside of the shell is provided on the chamber, and a limiting hole is provided on the side of the chamber close to the fluid channel, and a guide rod is slidably connected to the guide hole, and one end of the guide rod extends to the inside of the limiting hole and is connected to a third spring, and the other end of the third spring is connected to the bottom of the limiting hole. The guide rod located in the chamber is symmetrically rotated and connected to a rotating rod, and the lower locking rod passes through the second through hole and is rotatably connected to the other end of the rotating rod. Its function or effect: when the upper pressure plate or the lower pressure plate is pressed, the fluid channel is quickly opened or closed, and then the valve is quickly opened or closed.

[0008] Preferably, when the fluid channel is connected, the locking rod passes through the first through hole and is locked inside the lock hole, and the end of the locking rod abuts against the notch provided on the groove wall of the valve groove. Its function or effect is: when the fluid channel is connected, the locking in this state is realized; that is, when the valve is in the open state, the valve in this state can be locked to avoid accidental touch.

[0009] Preferably, when the fluid channel is closed, the valve port provided on the valve plate is staggered with the fluid channel, and the locking rod passes through the first through hole and abuts against the side wall of the valve plate. Its function or effect is: when the fluid channel is closed, the locking in this state is achieved; that is, when the valve is in a closed state, the valve in this state can be locked to avoid accidental touch.

[0010] Preferably, the lower end of the valve slot is provided with limit slots on both sides, and the lower end of the valve plate is connected with sliders on both sides, and the sliders are slidably connected in the limit slots. Its function or effect is: when the valve plate moves up and down in the valve slot, it can move within a predetermined vertical distance to avoid separation. When the slider reaches the upper end of the limit slot, the valve is just in a closed state and locked; and when the slider reaches the lower end of the limit slot, the valve is just in an open state and locked.

[0011] Preferably, the upper end of the housing is provided with an upper pressure groove that cooperates with the upper pressure plate. Its function or effect is to enable the fluid channel, i.e., the valve to be opened when the upper pressure plate and the upper pressure groove cooperate with each other, so as to facilitate observation of whether the valve is in an open state.

[0012] Preferably, the other end of the guide rod extends outwardly and is connected to a lower pressure plate, and the lower end of the shell is provided with a lower pressure groove that cooperates with the lower pressure plate. Its function or effect is: when the lower pressure plate and the lower pressure groove cooperate with each other, the fluid channel, i.e., the valve, is closed, making it convenient to observe whether the valve is in a closed state.

[0013] The beneficial effects achieved by the present invention are as follows: the valve system capable of rapid opening and closing proposed by the present invention can realize rapid opening or closing of the valve, saving time and effort, making it faster to open or close the valve and improving time efficiency; and the valve can be locked in both open and closed states to avoid accidental touch; at the same time, when the valve is in the open or closed state, the upper pressure plate or the lower pressure plate is in a state of protruding outward, making it easy to observe whether the two states of the valve are in place.

[0020] See attached Figure 1-3The valve system capable of rapid opening and closing comprises a housing 1, wherein a fluid channel 2 is arranged in the housing 1 along the length direction, wherein a slide groove 3 is symmetrically arranged in the housing 1 at the lower end of the fluid channel 2, wherein a locking block 4 is slidably connected in the slide groove 3, wherein a first spring 5 is arranged between the locking block 4 and the bottom of the slide groove 3, and an upper locking rod 6 and a lower locking rod 7 are respectively connected to the upper and lower ends of the two locking blocks 4,

[0021] The housing 1 is provided with valve slots 8 symmetrically in the vertical direction, and a matching valve plate 9 is slidably connected to the valve slot 8. The upper ends of the two valve plates 9 extend to the outside of the housing 1 and are commonly connected to an upper pressure plate 10.

A first through hole 13 communicating with the valve slot 8 is provided on the upper end of one side close to the two slide slots 3. The upper locking rod 6 passes through the first through hole 13 and is clamped in the lock hole 12. A valve port 14 matching the fluid channel 2 is provided on the valve plate 9.

[0022] A chamber 15 is provided in the shell 1, and a second through hole 16 communicating with the chamber 15 is opened at the lower end of the side close to the two slide grooves 3. A guide hole 17 communicating with the outside of the shell 1 is provided on the chamber 15. A limiting hole 18 is provided on the side of the chamber 15 close to the fluid channel 2. A guide rod 19 is slidably connected to the guide hole 17. One end of the guide rod 19 extends to the inside of the limiting hole 18 and is connected to a third spring 20. The other end of the third spring 20 is connected to the bottom of the limiting hole 18. The guide rod 19 located in the chamber 15 is symmetrically rotatably connected to a rotating rod 21. The lower locking rod 7 passes through the second through hole 16 and is rotatably connected to the other end of the rotating rod 21.

[0023] When the fluid channel 2 is connected, the locking rod 6 passes through the first through hole 13 and is clamped in the locking hole 12 , and the end of the locking rod 6 abuts against the notch provided on the groove wall of the valve groove 8 .

[0024] When the fluid channel 2 is closed, the valve port 14 provided on the valve plate 9 and the fluid channel 2 are staggered with each other, and the locking rod 6 passes through the first through hole 13 and abuts against the side wall of the valve plate 9 .

[0025] Limiting grooves 22 are provided at both sides of the lower end of the valve groove 8 , and sliding blocks are connected to both sides of the lower end of the valve plate 9 . The sliding blocks are slidably connected in the limiting grooves 22 .

[0028] The working principle is as follows: Figure 1 When the valve is in the open state, that is, the fluid channel 2 is in the connected state, and it needs to be closed, the lower pressure plate 24 is pushed to move in the direction of the lower pressure groove 25, so that the lower pressure plate 24 and the lower pressure groove 25 cooperate with each other, so that the upper end of the guide rod 19 moves toward the bottom of the limiting hole 18, the third spring 20 is compressed, and the rotating rod 21 rotatably connected to the guide rod 19 pushes the lower locking rod 7 to move, and then pushes the locking block 4 to move toward the bottom of the groove 3, the first spring 5 is compressed, so that the upper locking rod 6 connected to the locking block 4 moves toward the bottom of the groove 3, so that the upper locking rod 6 disengages from the locking hole 12, at this time, the compressed second spring 11 restores the elastic force and pushes the valve plate 9 outward, so that the slider moves to the top of the limiting groove 22, so that the valve port 14 set on the valve plate 9 and the fluid channel 2 are staggered with each other, to achieve the closing of the valve; in the closed state, the upper pressure plate 10 is away from the upper pressure groove 23, and the lower pressure plate 24 and the lower pressure groove 25 cooperate with each other.

[0029] like Figure 2 When the valve is in a closed state, that is, the fluid channel 2 is in a closed state, when it needs to be opened, the upper pressure plate 10 is pushed to move toward the upper pressure groove 23, so that the upper pressure plate 10 and the upper pressure groove 23 cooperate with each other, that is, during the downward movement of the upper pressure plate 10, the valve plate 9 moves downward, and when the valve plate 9 moves downward to the specified position, that is, the slider connected to the valve plate 9 moves to the bottom of the limit groove 22, the second spring 11 is compressed, and the fluid channel 2 is connected to the valve port 14 at this time. The elastic force of the first spring 5 and the third spring 20 is restored to make the two locking blocks 4 approach each other, so that the upper locking rod 6 connected to the locking block 4 and the lock hole 12 cooperate with each other to lock, thereby realizing the opening of the valve. When the valve is open, the upper pressure plate 10 and the upper pressure groove 23 cooperate with each other, and the lower pressure plate 24 is away from the lower pressure groove 25.

[0030] In addition, the purpose of the symmetrically arranged components or parts in the figure is to improve the use effect and make the force more uniform, thereby increasing the service life.
