Most of the existing stop valves are fixed to the pipeline by bolts, which is extremely troublesome during the loading and unloading process.

Description

Technical Field

[0001] The invention relates to the technical field of valves, and in particular to a stop valve applied to a fluid containing sediment particles. Background Art

[0002] The stop valve usually closes the connecting hole by the cooperation of the valve disc and the valve seat. The valve seat is fixedly installed in the connecting hole. Therefore, the through hole in the valve seat is blocked by rotating the valve disc to prevent water from flowing through.

[0003] If there is sand or hard particles in the medium, they will easily settle on the sealing surface of the valve seat, causing the valve seat and the valve disc to not be tightly sealed, affecting the normal use of the stop valve.

[0004] However, as for the current traditional stop valve used for fluids containing mud and sand particles, the structure of its valve disc is imperfect, so that when the valve disc is closed, mud and hard particles will be stuck between the valve disc and the valve seat, thereby affecting the sealing of the stop valve. In addition, the existing stop valves for fluids containing mud and sand particles lack a structure that is easy to load and unload. When in use, the stop valve is often blocked due to the flow of fluid containing particles inside, and it needs to be disassembled and unblocked frequently. Most of the existing stop valves are fixed to the pipeline by bolts, which is extremely troublesome during the loading and unloading process. Summary of the invention

When the valve needs to be closed, the slider is moved up by pulling the sliding rod so that the slider fits with the bottom of the partition, thereby blocking the lower end of the through hole in the partition. By arranging a roller at the outer end of the slider, when a granular object is stuck between the slider and the partition, the rotating shaft can be driven to rotate by the push of the fluid to push the granular object away. By opening a through hole on the slider, when the slider blocks the through hole on the partition, the fluid without particles can continue to pass through the partition and flush the partition.
