Description

Technical Field

[0001] The invention relates to the technical field of sealing valves, in particular to a sealing valve used for the circulation of solid-liquid mixtures. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. They are valves used in fluid control systems.

[0003] The existing sealing valve has the following inconveniences:

[0004] In the process of not needing to transport materials, it is necessary to use a valve to cut off the materials to prevent the materials from continuing to flow. However, after the valve has been used for a long time, the internal seals will be corroded to a certain extent. At the same time, the flow of materials will impact the seals, which will also cause a certain amount of wear on the seals. When the seals are worn, they cannot provide a good sealing effect, and leakage will occur. The existing sealing valves on the market all close the valve by rotating the valve handle, but it takes a certain amount of time to close the valve in this way, and the valve cannot be closed instantly, so when an emergency occurs, it cannot be handled in time.

[0035] Embodiment 1, as Figure 1-4 As shown, when closing the valve, first press the pressure plate 5 downward, the pressure plate 5 drives the connecting rod A6, the push rod 3, the connecting plate 4, and the spring A7 to move downward, and compress the spring A7. When the push rod 3 moves down to the specified position, it squeezes the limit frame 8, so that the two sets of limit frames 8 gradually approach each other. When the push rod 3 moves down to the specified position, the limit frame 8 covers the top of the connecting plate 4, limits the connecting rod A6, and prevents the spring A7 from resetting.

[0036] Embodiment 2, as Figure 1-4 As shown, when the connecting rod A6 moves downward, the connecting rod A6 drives the stabilizing block 12, the connecting rod C18, the lower push plate 14, and the connecting rod B17 to move, and then drives the base 15, the sealing plug A13 and the sealing plug B21 to move downward. When the base 15 moves down to the bottom, the connecting rod B17 slides along the outer sleeve 24 and drives the spring C25 to be compressed. When the lower push plate 14 moves down to the specified position, the lower push plate 14 squeezes the two groups of sealing plugs A13, so that the two groups of sealing plugs A13 are separated, and then drives the sealing plugs A13 and the sealing plugs B21 to extend to both sides of the valve compartment 1, so that the valve is closed. When the sealing plug A13 moves to the specified position and no longer moves, the lower push plate 14 drives the moving rod 20 and the spring D27 to move through the guide block 16, so that the sealing plug B21 continues to extend, so that the sealing plug A13 and the sealing plug B21 seal the valve pair.

[0037] Working principle: When closing the valve, first press down the pressure plate 5, the pressure plate 5 drives the connecting rod A6, the push rod 3, the connecting plate 4, and the spring A7 to move downward, and compress the spring A7. When the push rod 3 moves down to the specified position, it squeezes the limit frame 8, so that the two sets of limit frames 8 gradually approach each other. When the push rod 3 moves down to the specified position, the limit frame 8 covers the top of the connecting plate 4, limits the connecting rod A6, and prevents the spring A7 from resetting.

[0038] When the connecting rod A6 moves downward, the connecting rod A6 drives the stabilizing block 12, the connecting rod C18, the lower push plate 14, and the connecting rod B17 to move, and then drives the base 15, the sealing plug A13, and the sealing plug B21 to move downward. When the base 15 moves down to the bottom, the connecting rod B17 slides along the outer sleeve 24 and drives the spring C25 to be compressed. When the lower push plate 14 moves down to the specified position, the lower push plate 14 squeezes the two groups of sealing plugs A13, so that the two groups of sealing plugs A13 are separated, and then drives the sealing plugs A13 and the sealing plugs B21 to extend to both sides of the valve compartment 1, so that the valve is closed. When the sealing plug A13 moves to the specified position and no longer moves, the lower push plate 14 drives the moving rod 20 and the spring D27 to move through the guide block 16, so that the sealing plug B21 continues to extend, so that the sealing plug A13 and the sealing plug B21 seal the valve pair;

[0039] When the valve needs to be opened, first pull the two sets of limit frames 8, the limit frames 8 are adsorbed on the magnet 9, and then the spring A7 is reset to push the connecting rod A6 upward, and the connecting rod A6 drives the stabilizing block 12, the connecting rod C18, the lower push plate 14, and the connecting rod B17 to move upward. At this time, the lower push plate 14 no longer limits the sealing plug A13 and the guide block 16, and then the spring B23 and the spring D27 are reset to make the sealing plug A13 and the sealing plug B21 return to the initial position and no longer seal the valve, and then the base 15, the sealing plug A13 and the sealing plug B21 move up to their original positions.

[0040] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
