Abstract
The electricity plate unloading valve that surges belongs to the control valve technical field.This valve comprises valve body, push-pull valve and control gear, and three push-pull valves of upper, middle and lower and four valve bodies are arranged, and three push-pull valves, four interlaced serial connections of valve body connect, and a push-pull valve is set between two adjacent valve bodies; Last push-pull valve is provided with manual spiral control handwheel; In, the lower plugboard valve is respectively equipped with the Electrohydraulic push rod of hydraulic control, install by support between Electrohydraulic push rod and the push-pull valve to be connected.The utility model is rational in infrastructure simple, manufactures easily, and cost is low, and usability is good.Do not get stuck, do not leak material, maintenance is convenient, and the quantitative validity of discharging is good, high working efficiency, the long service life of equipment.Needing in the modern industry can be widely used in the field such as metallurgy, chemical industry, food of quantitative discharging, excellent popularization using value and wide market prospects are arranged.
Description
Technical field
The utility model relates to a kind of structure of Double-deck cinder discharge valve, belongs to the control valve technical field.
Background technique
Existing Double-deck cinder discharge valve is made of last unloading valve, following unloading valve, middle ash bin and drive unit etc., unloading valve disposes up and down by middle ash bin up and down, drive unit and unloading valve and middle ash bin relative fixed up and down, and the control switching of unloading valve up and down respectively.The high leak tightness Double-deck cinder discharge valve of number of patent application 03251527.8 for example, last unloading valve and following unloading valve are by valve body, valve seat and valve gap constitute, valve seat and valve body fix, valve gap is installed in rotation on the valve body by supporting axle, valve gap and back shaft fix, the working surface that matches with valve gap in the valve seat lower end is the plane, the valve seat working surface is provided with seal ring, one end of valve gap supporting axle stretches out valve body, and on the section of stretching out, fix a swing arm, swing arm is provided with the valve gap resetting means, the position of the swing arm on the two unloading valve valve gap supporting axles is corresponding up and down, be fixed with crank on the drive unit output shaft, the position of this crank and size are coordinated the position of valve gap back shaft top link separately mutually with unloading valve up and down.Existing Double-deck cinder discharge valve structure more complicated, control accuracy is poor, often occurs the phenomenon that gets stuck in the running, influences working efficiency and quality.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at existing unloading valve, provides a kind of rational in infrastructure, avoids getting stuck, and helps increasing work efficiency the electricity of the long service life plate unloading valve that surges.
The purpose of this utility model is to realize by the improvement to existing unloading valve, the electricity plate unloading valve that surges, comprise valve body, push-pull valve and control gear, it is characterized in that being provided with three push-pull valves of upper, middle and lower and four valve bodies, three push-pull valves, four interlaced serial connections of valve body connect, and a push-pull valve is set between two adjacent valve bodies; Last push-pull valve is provided with manual spiral control handwheel; In, the lower plugboard valve is respectively equipped with the Electrohydraulic push rod of hydraulic control, install by support between Electrohydraulic push rod and the push-pull valve to be connected.
Described push-pull valve is provided with edge of a knife plate, cutter type flashboard, U type Sealing and upper and lower Stamping Steel Ribbon, U type Sealing is arranged between the adpting flange of two adjacent valve bodies, edge of a knife plate be arranged on cutter type flashboard above, upper and lower Stamping Steel Ribbon is arranged on the upper and lower both sides of cutter type flashboard, and cutter type flashboard connects Electrohydraulic push rod.
Last push-pull valve is a normally open valve, generally is controlling plate on the handwheel rotary closing by spiral under maintenance or the case of emergency.In, the lower plugboard valve is operating valve, by in, the circulation of lower plugboard valve opens and closes, and carries out the repetition discharging.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, and usability is good.When wet feed sticked on the cutter type flashboard, push-pull valve will be eliminated by edge of a knife plate when opening or closing on the push-pull valve, reached not get stuck.When if cutter type flashboard can not lock puts in place during discharging,, improve the control accuracy of push-pull valve by will withdraw the automatically emersion again and can repeat automatic withdrawal and rise from again until cutter type flashboard lock and put in place of Electrohydraulic push rod self function and electrical equipment control cutter type flashboard.Maintenance is convenient, and general only need control plate on the handwheel rotary closing by spiral, does not need discharge system work is pulled down or stopped to push-pull valve, just can carry out timely maintenance service to equipment; After U type Sealing has had wearing and tearing, can regulate U type Sealing by peripheral bolt, reach and do not leak material, improve quantitative validity and the working efficiency of discharging, prolong the working life of equipment.
