Abstract
The utility model discloses a double rack plate gate valve for the cement industry, which comprises a valve body, a valve plate, a guide pulley, a transmission shaft, gears, racks, sprockets, an industrial chain and an electric reduction box, wherein the electric reduction box is fixed on the valve plate, the guide pulley is arranged below the valve plate, two rows of racks are installed on the valve body, one sprocket is respectively arranged on the electric reduction box and the transmission shaft, the two sprockets are connected together via the industrial chain, and two gears which can move along the racks are installed on the transmission shaft. The valve plate of the utility model can stably and flexibly move, small friction is generated between the valve plate and the valve body, and the structure is compact and reasonable.
Description
Technical field
The utility model relates to a kind of plate valve, is 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 purpose of this utility model is in order to solve the deficiencies in the prior art, provides that a kind of stable drive is reliable, simple in structure, wearing and tearing cement industry double rack plate valve little, low cost of manufacture.
The technical solution of the utility model 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, connect 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 utility model 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.
The beneficial effects of the utility model: 1, wearing and tearing are little between steady, flexible 2, valve plate of valve plate motion and the valve body; 3, compact structure, rationally.
