Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic valves, in particular to a wired high-pressure electromagnetic emergency cut-off valve. Background Art

[0002] In order to ensure the safety of gas use, a gas emergency shut-off valve is set at the outlet of the gas storage tank / pipeline. The gas emergency shut-off valve is used to cut off the source of upstream hazardous materials in the event of equipment failure, corrosion damage, seal failure, leakage, or emergency, so as to avoid the expansion of the scope of the accident, control the impact of the accident, and reduce the loss of the accident. For example, a Chinese patent for an efficient electromagnetic gas emergency shut-off valve, patent number (CN206419519U), is provided with a blocking and a block. When the handle is turned, the threaded rod is driven to move in the threaded sleeve, so that the connecting rod drives the blocking block to move downward, so that the blocking block cooperates with the block to close the valve body, thereby blocking the gas. The threaded rod is inserted into the valve body, and the gas in the valve is easy to overflow from the gap between the threaded rod and the valve body, resulting in insufficient sealing.
