Abstract

The invention discloses a fire-proof emergency cut-off ball valve with rapid response. The fire-proof emergency cut-off ball valve comprises a ball valve main body, a valve rod, a fire-resistant box,an executing mechanism, a fixed screwing part, a movable screwing part and a main fire-proof sealing ring; and the valve rod is arranged on the ball valve main body, the valve rod extends into the fire-resistant box, the fixed screwing part is arranged at the top end of the valve rod, the main fire-proof sealing ring is arranged at the joint between the valve rod and the fire-resistant box, the executing mechanism capable of being remotely controlled is arranged in the fire-resistant box, an action rod is arranged on the executing mechanism, the executing mechanism can drive the action rod toperform lifting and rotating actions, and the movable screwing part matched with the fixed screwing part is fixed at the bottom of the action rod. According to the fire-proof emergency cut-off ball valve, the valve can be quickly and effectively closed through the executing mechanism under emergency conditions such as a fire disaster through the combination of the fixed screwing part and the movable screwing part.

Description

【Technical field】 [0001] The invention relates to the technical field of valves, in particular to the technical field of fireproof emergency shut-off ball valves. 【Background technique】 [0002] With the shortage of international energy sources, countries around the world have developed a large number of reserve oil industries and increased reserve oil depots. With the development of technology, the capacity of oil pipelines and the scale of tank farms are also increasing, and the requirements for fire prevention are becoming more and more stringent. For the safety of the tank area, it is necessary to take isolation measures at the root of the spherical tank. When a fire occurs, the communication between the tanks is cut off through the valve to reduce the danger of the fire and reduce the loss. The reliability of the existing emergency cut-off ball valve is not ideal enough, and the response is not fast enough. 【Content of invention】 [0003] The purpose of the present ...
