Abstract
The invention discloses a manual knife valve suitable for phosphoric acid extraction. The manual knife valve comprises a valve body, a valve rod protective sleeve (1), a valve rod (2), a knife plate lifting mechanism (3) and a valve plate (8), and is characterized in that the knife plate lifting mechanism (3) adopts a manual mechanism, wherein a throttle hole (7.1) is formed in middle of the valve plate (7); and a receiving tank (19) is arranged at the bottom of the valve body, and is connected with a drained liquid receiving pipe port (20). The manual knife valve is suitable for wear and corrosion damage of such mediums as pulp and phosphoric acid slurry with a solid content within 70% to a valve flowing part, is easy to be opened/closed, is short in closure distance, reduces the blockage, preferably solves the medium leakage collection, improves the operation environment, greatly prolongs the service life of the valve, reduces the use cost, and brings more benefits for production.
Description
Technical field
The invention belongs to damming in chemical industry ore dressing on pipeline, flow control valve, be especially applicable to the damming of phosphoric acid extraction, flow control valve structure technology.
Background technique
In existing chemical industry ore dressing plant production process, usually select the valves such as gate valve, tapered plug valve, ball valve for solid content damming within 70% on the medium transport such as ore pulp, phosphoric acid material pulp pipeline, Flow-rate adjustment; Material has cast steel, stainless steel (304,1Cr18Ni9Ti, 316L), PP, Fen Chuo plastics etc.What above valve all adopted is that electric lifting mechanism control valve opens and closes; In use electric lifting mechanism also exists the problems such as keying operation is difficult, control rhythm is unstable, valve price is high.Also there is the distance that dams, easy blocking, easily leak material, valve body can be caused to denude, corrode, form valve shortening in working life; The valve material price of this structure is high on the other hand, adds cost of production, have impact on the driving rate of equipment to a great extent.
Summary of the invention
Object of the present invention just in order to overcome the keying operation that above-mentioned original technology exists difficult, control that rhythm is unstable, valve body abrasion, the defect of valve body etching problem and not enough and a kind of phosphoric acid extraction hand knife valve being suitable for chemical industry, ore dressing is provided.
The present invention is achieved by the following technical solution.
Be applicable to a hand knife valve for phosphoric acid extraction, comprise valve body, valve guard pipe, valve rod, knife plate elevator mechanism, valve plate, feature of the present invention is: knife plate elevator mechanism adopts man-operated mechanism; Throttle orifice is offered in the middle of valve plate; Be provided with splicing case at body base to be connected with drain connection mouth.
The throttle orifice center of circle of the present invention to be opened on valve plate center line and to be positioned at valve plate bottom.
Splicing case upper end of the present invention adopts splicing case attachment bolt to be connected with body base by splicing case flange.
Knife plate elevator mechanism of the present invention adopts bevel gear transmission: by a handle wheel connection for transmission axle, driving sleeve is located on fixed case; Driving wheel is fixed with, sheathed follower on valve rod in transmission shaft termination; Taken turns by rocking-turn active handle, make driving wheel drive follower to rotate, thus valve rod is moved up and down.
The present invention carries out finishing structure and improves on traditional cutter valve, 1), manual knife plate elevator mechanism is adopted to be realized pneumatic, electronic transmission; 2), throttling is formed at valve plate central aperture; 3), increase splicing case and is connected with drain connection mouth, realize getting rid of leakage smoothly and expect.Valve latus rectum of the present invention is suitable for 50 ~ 1000mm; Temperature-20 DEG C ~ 120 DEG C; Working pressure≤0.6MPa, medium is ore pulp, the damming of phosphoric acid, phosphor ammonium slurry, Flow-rate adjustment.
The invention has the beneficial effects as follows, by at valve plate, valve body flow passage components finishing procedures, obtained be applicable to damming in the liquid delivery process of chemical industry ore dressing plant, the model utility cutter valve of Flow-rate adjustment solves temperature-20 DEG C ~ 120 DEG C preferably, working pressure≤0.6MPa, being applicable to medium is that ore pulp, phosphoric acid, phosphor ammonium slurry are to the abrasion of flow passage components, corrosion-damaged, open and close easily, solve the collection of dielectric leakage preferably, improve operating environment.Substantially prolongs the working life of valve, reduce user cost, bring very large benefit to production.
This cutter valve adopts perforate in plate, shortens distance of damming; Decrease abrasion, erosional surface; Manually-operable, cost of investment are low and open and close easily, divide into Material collecting box for harvesting, solve the collection of dielectric leakage preferably, improve operating environment.Substantially prolongs the working life of valve, reduce user cost, bring very large benefit to production.
