Abstract

The utility model relates to a flat plate valve gate used for controlling material flow rate. The flat plate valve gate comprises a valve body, valves arranged on the valve body, and a driving mechanism driving the valves to move, wherein the valves comprise a left valve and a right valve which are symmetrically arranged on the valve body. The flat plate valve gate has the advantages that firstly, through the adoption of the arrangement manner of the valves, material is guaranteed to drop down in the middle, and through the adoption of the size of openings of the valves, the flow rate of the material can be effectively controlled, so that the material can be timely conveyed after dropping down and the phenomenon of blockage cannot occur; and secondly, the flat plate valve gate is provided with a surrounding plate made of wear-resistant material, thereby prolonging the service life of the inner wall of the valve body.

Description

The flap type lock

Technical field

The utility model relates to a kind of flap type lock that is used to control mass flow, belongs to the load transfer device technical field.

Background technology

On the present domestic pipe conveying equipment, the unidirectional flat gate valve of the many employings of flow control, this valve is one-sided discharging, material all falls within on the inner-walls of duct of a side, latch up phenomenons such as easily arch camber, tubulose be logical overflows, interior sticking storehouse, and material causes the damage of inwall easily to the impact of inwall, to having a strong impact in service life of pipeline.

The utility model content

The utility model is at above-mentioned defective, and purpose is to provide a kind of material blanking placed in the middle, thereby guarantees the flap type lock of material smooth delivery of power.

The technical solution of the utility model is: the driver train that the utility model comprises valve body, is arranged on the valve on the valve body and drives valve motion, valve comprises left valve and the right valve that is symmetricly set on the valve body.

Described left valve, right valve be synchronous reverse motions under drive mechanism.

Establish coaming plate between left side valve, right valve and the valve interior wall.

An Electrohydraulic push rod is respectively established in the valve body both sides, and Electrohydraulic push rod connects corresponding valve separately.

The utility model has the advantages that: 1) set-up mode of the utility model valve guarantees that material falls between two parties, and the flow by the effective control material of being provided with of valve openings size, and backwardness can be carried timely, phenomenon of blocking can not take place; 2) the utility model is provided with the coaming plate of being made by high-abrasive material, has improved the service life of valve interior wall.
