Abstract

Disclosed is a valve mechanical linkage system. A valve comprises a main valve and a secondary valve; the system comprises a first transmission mechanism and a second transmission mechanism; the first transmission mechanism is connected with the main valve and used for converting the up-and-down reciprocating motion of the main valve into a rotational reciprocating motion; the first transmission mechanism and the second transmission mechanism are connected by means of a coupling (4), and the rotational force of the rotational reciprocating motion is transferred to the second transmission mechanism by means of the coupling (4); the second transmission mechanism is connected with the secondary valve, and achieves on-off control on the secondary valve by converting the rotational reciprocating motion into the up-and-down reciprocating motion.
