Description

Technical Field

[0001] The utility model relates to the technical field of chokes, in particular to a choke fixing device. Background Art

[0002] Electric emergency shut-off valves play a vital role in chemical production. Chlorine gas is highly toxic and corrosive, and a leak could have devastating consequences. Therefore, ensuring the safety of chlorine cylinders and dosing systems is crucial. Electric emergency shut-off valves can quickly shut off the flow path in an emergency, preventing further chlorine leakage, effectively preventing further accidents and ensuring the safety of personnel and equipment. Specifically, in the event of an emergency, such as when the temperature or pressure within the equipment exceeds set limits, the valve coil of the electric emergency shut-off valve is momentarily energized, triggering the valve to rapidly close and enter a self-locking state. At this point, even if power is removed, the valve remains closed and does not automatically reopen. This design ensures the reliability and stability of the electric emergency shut-off valve in critical moments.

[0003] However, the electric emergency shut-off valve needs to be fixed to the bottle mouth. The existing method uses a flat end seal between the angle valve and the bottle valve using a clamp. The seal preload is provided by a bolt on the clamp, which has no anti-loosening or anti-retraction measures. This structure is prone to chlorine leakage from the flat end face between the valves when the pipeline vibrates or the valve is opened and closed. This is harmful to the environment and operators. The leaked chlorine can corrode the metal parts in the chlorination room. Utility Model Content

[0034] In a possible implementation, the angle valve buckle 200 , the angle valve buckle lower cover 210 , and the movable joint conversion member 300 are all made of metal.

[0035] Specifically, since chlorine is corrosive to a certain extent, metal materials are used because metal has good corrosion resistance, which can extend the service life of the angle valve buckle 200, the angle valve buckle lower cover 210 and the flexible joint conversion part 300.

A pressure gasket is set. The pressure gasket is set inside the cover nut 310 and is suitable for connection with the delivery angle valve at the top of the second joint 330. Sealant is set at the connection position to better ensure the sealing and avoid the escape of chlorine.
