Abstract

The invention discloses a tornado valve operating mechanism, comprising a main spiral arm, a plurality of auxiliary spiral arms, a transmission rod and an elastic piece, wherein the main spiral arm is connected with one end of the transmission rod; the elastic piece is connected with the other end of the transmission rod; a heavy punch is arranged on the main spiral arm; the auxiliary spiral arms are connected onto the transmission rod between the main spiral arm and the elastic piece; the main spiral arm and the auxiliary spiral arms are respectively sheathed on rotating shafts. According to the tornado valve operating mechanism, as an original executing mechanism and an original complexity control system which are high in manufacturing cost are replaced by a spring and heavy punch combined mechanism, not only is the cost lowered, but also the time on closing a valve in the coming of a tornado is less than 0.25s; therefore the damage caused by the tornado is furthest prevented; the cost is decreased greatly; due to no energy consumption of the executing mechanism, the energy is saved and the environment is protected; all functions are automatically finished, so that personal operation is needless.

Description

technical field [0001] The invention relates to the fields of heating, ventilation and air conditioning, in particular to a tornado valve operating mechanism. Background technique [0002] The existing tornado valve is operated by an actuator, and when a tornado comes, the closing time of the valve is as short as 0.5 seconds, and the closing time is longer, and the cost of the actuator is high and the production cost is high. Contents of the invention [0003] Purpose of the invention: In order to solve the deficiencies of the prior art, the present invention provides a tornado valve operating mechanism. [0004] Technical solution: a tornado valve operating mechanism, the operating mechanism includes a main swing arm, a secondary swing arm, a transmission rod and an elastic member, the main swing arm is connected to one end of the transmission rod, and the elastic member is connected to the other end of the transmission rod , the main swing arm is provided with a weight,...
