Abstract
The invention discloses a double-rack flat gate valve for the cement industry. The double-rack flat gate valve comprises a valve body, a valve plate, a guide wheel, a transmission shaft, gears, racks, chain wheels, an industrial chain and an electric speed reducer. The electric speed reducer is fixed on the valve plate; the guide wheel is arranged below the valve plate; the two rows of racks are arranged on the valve body; one chain wheel is mounted on the electric speed reducer and the transmission shaft respectively; the two chain wheels are connected through the industrial chain; and the two gears capable of moving along the racks are mounted on the transmission shaft. The invention has the advantages that the movement of the valve plate is stable and flexible, the abrasion between the valve plate and the valve body is less and the structure is compact and reasonable.
Description
Technical field
The present invention relates to a kind of plate valve, be specifically related to a kind of cement industry double rack plate valve.
Background technique
Cement industry uses the operating ambient temperature of plate valve below 300 ℃, bore big (usually more than 1600mm), as adopt general leading screw to pass, the valve plate bumpy motion, switching speed is slow, and leading screw is easy to wear, if adopt hydraulic jack to promote, inapplicable for large-scale gate valve, because stroke is long, the piston rod poor stability, piston rod is for a long time exposed in addition is operated in outdoorly, also is unallowed, and the manufacture cost height, also be inapplicable for large-scale gate valve, present domestic this suitable series products that lacks.
Summary of the invention
The objective of the invention is in order to solve the deficiencies in the prior art, provide a kind of stable drive reliable, simple in structure, wearing and tearing cement industry double rack plate valve little, low cost of manufacture.
Technological scheme of the present invention is: a kind of cement industry double rack plate valve, comprise valve body, valve plate, upper saw pulley, transmission shaft, gear, tooth bar, sprocket wheel, industrial chain and electric reducer, described electric reducer is fixed on the valve plate, the valve plate below is provided with upper saw pulley, two tooth-arranging strips are installed on the described valve body, a sprocket wheel respectively is installed on described electric reducer and the transmission shaft, is connected by industrial chain between two sprocket wheels, being equipped with two on the transmission shaft can be along the gear that moves on the tooth bar.
As preferably, rolling bearing is adopted in the supporting of described transmission shaft, and frictional force is little, rotates flexibly.
As preferably, described two tooth-arranging strips are fixed on the valve body with line parallel symmetry in the valve body.
As preferably, described valve plate is the seal case beam structure, and the intensity height is out of shape for a short time, and under the upper saw pulley supporting, valve plate does not contact with not having directly between the valve body in the opening and closing process, and is very flexible when making valve plate work.
Working principle of the present invention is: the electric reducer that sprocket wheel is housed is fixed on the valve plate, electric reducer rotates, driving transmission shaft by industrial chain rotates, gear is also rotated thereupon, because of tooth bar is fixed on the valve body motionless, gear then rotates on one side, moves forwards or backwards along tooth bar Yi Bian drive valve plate, is engaged in the unlatching of realization valve or closes.
Beneficial effect of the present invention: 1, wearing and tearing are little between steady, flexible 2, valve plate of valve plate motion and the valve body; 3, compact structure, rationally.
