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 (), and the rotational force of the rotational reciprocating motion is transferred to the second transmission mechanism by means of the coupling (); 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.

A double-plate gate valve includes a valve body, a valve cover, a valve stem, a guide plate, a goggle plate assembly, a diversion hole assembly, a disc spring assembly and a valve plate and wedge assembly. The goggle plate assembly provides mounting support for the diversion hole assembly and the valve plate and wedge assembly in the valve chamber, the goggle plate assembly is movable along with the diversion hole assembly and the valve plate and wedge assembly in the valve chamber, and floating seals are formed at a contact surface between the diversion hole assembly and the guide plate, and at a contact surface between the valve plate and wedge assembly and the guide plate. A face-to-face distance and a sealing force between a sealing surface of the diversion hole assembly and a sealing surface of the valve body are adjustable.

A disc valve with a diversion hole for a solid granule medium aims to solve the problem of material accumulation in a valve cavity and includes a valve body with a valve passage, the valve cavity communicated with the valve passage is formed in the valve body, a valve disc for closing and opening the passage is arranged in the valve cavity, the valve disc is fixedly connected with a valve rod through a valve rod connecting hole of an eyeglasses plate, and the eyeglasses plate is also provided with the diversion hole and a hole for placing the valve disc. The outer wall diameter of the diversion hole is greater than the diameter of the valve passage, and the height of the diversion hole is the same as the length of the valve passage passing through the valve cavity.
