Abstract
The utility model provides a full-sealed electric plate gate for cement industry, which has controllable valve plate lifting clearance and reasonable stroke control. The electric plate gate comprises a lower valve body, a valve plate, a valve seat, a sealed upper valve body, a transmission device and a stroke control device. Moreover, rolling wheels are disposed on lateral sides of the valve plate, and convex guide rails are arranged at the positions of the valve seat corresponding to the rolling wheels. When the valve plate is positioned at the bottom portion of the valve body, the guild rails are disconnected at the position of the rolling wheels. Furthermore, the stroke control device comprises a lead screw, a lead screw nut, a sliding rod, a locating block and a stroke switch. In addition, the transmission device employing pulley transmission includes a fixed pulley, a free pulley, a steel rope and a rope wheel, wherein the fixed pulley is arranged at the top end of the valve body, the free pulley is disposed at the top end of the valve plate, the steel rope and the rope wheel are used for traction, and the rope wheel is driven by a speed reducer. The utility model has the advantages that 1, the valve plate operation can be benefited as nearly no friction exists between the lifted valve plate, 2, controlling requirements can be satisfied as the stroke control device is mounted outside the valve body, 3, a steel wire pulley used for transmission is simple and reliable, and 4, the upper valve body is fully sealed.
Description
Technical field
The utility model relates to a kind of driven plate gate, is specifically related to the electronic bulkhgead gate of a kind of cement industry.
Background technique
In the existing cement industry, the working environment of this kind equipment is that temperature height, dust are many, and the specification that needs is many, present domestic this suitable series products that also do not have.
Summary of the invention
The purpose of this utility model provides that a kind of valve plate lifting gap is controlled, the electronic bulkhgead gate of the rational hermetically sealed cement industry of Stroke Control.
The technical solution of the utility model is: the electronic bulkhgead gate of a kind of cement industry, comprise valve body, valve plate, valve seat, sealing upper valve body, transmission device and travel control device down, the side of described valve plate is provided with roller, be provided with the guide rail of projection on the valve seat with the roller corresponding part, when valve plate was positioned at the valve body bottom, guide rail disconnected in the position of roller;
Described travel control device comprises screw mandrel, feed screw nut, slide bar, positioning block and position limit switch, described screw mandrel links to each other with speed reducer output shaft, screw mandrel is provided with the feed screw nut, the feed screw nut is connected with slide bar, slide bar is provided with positioning block, when valve plate drops to valve body bottom or is raised to the valve body top, positioning block touches position limit switch;
Described transmission device adopts the pulley transmission, comprises the static pulley that is arranged on the valve body top, is arranged on the movable pulley on valve plate top, the steel cable that is used to draw and rope sheave, and rope sheave is driven by speed reducer.
Because existing valve plate is in moving process, valve plate directly contacts with valve seat all the time, and the frictional force of surface of contact is bigger, has influenced the operation of valve plate.The utility model is provided with roller on the valve plate limit, when valve closing, valve plate still directly contacts with valve seat, is in air-tight state, when valve plate moves up, roller will roll on guide rail, valve plate breaks away from valve seat simultaneously, forms the gap, and valve plate does not directly contact with valve seat, the frictional force that big senior general is low between them, and can compensate thermal distortion.
Roller can respectively be provided with two on the both sides of valve plate, guide rail preferably is provided with the slope at gap, is convenient to roller and enters the guide rail operation.
When valve body is all-sealed structure, environment in the valve body is not suitable for installing position limit switch, the utility model is installed in travel control device outside the valve body, speed reducer output shaft drives screw mandrel and rotates, screw mandrel drives feed screw nut's to-and-fro motion, the feed screw nut drives positioning block and makes the position limit switch action, thus the control valve plate upper and lower position limit.
The beneficial effects of the utility model are: 1, during the valve plate lifting and valve seat frictional force almost do not have, help the operation of valve plate; 2, travel control device is installed in outside the valve body, has satisfied the control needs; 3, with fleet wheel transmission, simple and reliable; 4, upper valve body is hermetically sealed.
