Description
Technical field:
The present invention relates to a kind of infant industry high temperature liquid seal valve, particularly relate to a kind of low melting point, high activity metal (as: lithium, sodium, calcium, magnesium) in the high temperature refining process, have safe and reliable, the stable effectively valve of operation.
Background technique:
Low melting point, high activity metal (as: lithium, sodium, calcium, magnesium) never have a kind of safe, reliable, stable, effective pipeline valve and are applied in the industrialized production in high temperature refining production process.And the common hot industry valve that generally uses at present, owing to adopt nonmetal Sealing, operating temperature is all below 300 ℃; And the valve that adopts metal seal under the higher temperature condition, to work, owing to use movable valve to open and close valve, can not effectively solve valve inner and extraneous sealing problem under high temperature condition, the reactive metal that causes valve valve inner in use often to occur contacts with ambient air and chemical reaction takes place, produce metallic oxide, knot makes valve can not normally use, cause life of valve very short extremely at valve inner, and has big potential safety hazard.
The model utility content:
The utility model provides a kind of safe and reliable, stable in high temperature (300 °～800 ℃) refining process, effective pipeline high temperature hydraulic valve of high activity metal of guaranteeing at the deficiencies in the prior art.
For realizing above purpose, the technical solution adopted in the utility model is as follows:
A kind of infant industry high temperature liquid seal valve is made up of valve body, heating unit, thermal insulator, temperature measuring equipment, water-cooling tube, discharge nozzle, lower flange, cooling chamber, dividing plate, the disconnected chamber of envelope, supply pipe, upper flange, pure metal seal ring, electrical equipment control; Wherein the valve outer wall mounted on surface has heating unit, thermal insulator is arranged on the valve body periphery, the valve body two ends are welded with discharge nozzle and supply pipe respectively, be welded with lower flange and upper flange on discharge nozzle and the supply pipe respectively, valve inner is divided into disconnected chamber of envelope and cooling chamber by dividing plate, valve inner is provided with temperature measuring equipment, and cooling chamber is provided with water-cooling tube and communicates with cooling chamber inside.
Described heating unit, cooling tube and temperature measuring equipment link to each other with electrical equipment control respectively.
Described supply pipe and discharge nozzle form misconstruction at valve inner.
Each parts of described valve inner adopt no seam welding.
Described discharge nozzle, supply pipe adopt the pure metal seal ring to be connected by lower flange, upper flange with other pipelines.
The utility model can solve following technical problem: (1) utilizes the physical and chemical performance of material itself, and under heated condition, when the valve inner material reached fusing point and is in a liquid state, valve body was in opening state; (2) valve inner supply pipe and discharge nozzle form misconstruction at valve inner, can be made as the Liquid sealing valve of 180 °, 90 ° and other various angles, after making that each blowing is finished, can there be a small amount of material in the valve body, the cooling valve body, a small amount of material that its inside has is become solid-state by liquid state, the valve inner supply pipe is all sealed, valve body is in closed condition, and pipeline is sealed fully; (3) each parts of valve body adopt seamless welded seal to connect, adopt metal o-ring sealed type flange to be connected between valve and the pipeline, thereby definitely guaranteed can any contact do not taken place with ambient air at the reactive metal of condition of high temperature lower valve inside, any chemical reaction takes place, guarantee that high activity metal (as: lithium, sodium, calcium, magnesium) and alloy thereof are safe in the refining process, effectively stable under high temperature (300 °～800 ℃) condition thereby provide a kind of, in the industrial production applicable to the high activity metal refining.
Description of drawings:
Fig. 1 is the utility model structural representation;
Embodiment:
Plant infant industry high temperature liquid seal valve, form by valve body 1, heating unit 2, thermal insulator 3, temperature measuring equipment 4, water-cooling tube 5, discharge nozzle 6, lower flange 7, cooling chamber 8, dividing plate 9, the disconnected chamber 10 of envelope, supply pipe 11, upper flange 12, pure metal seal ring 13, electrical equipment control 14.
During concrete enforcement, liquid metal enters the disconnected chamber 10 of envelope through supply pipe 11, can in the disconnected chamber 10 of envelope, retain a small amount of liquid metal after flowing through, open cooling water by electrical equipment control 14 and enter cooling chamber 8 through water-cooling tube 5, the liquid metals that will seal in the disconnected chamber 10 by dividing plate 9 heat transfers are cooled to solid-state, thereby valve body 1 inner supply pipe 11 is shut, reached the closed state of valve, close cooling water simultaneously.During Open valve, connect heating unit 2 by electrical equipment control 14 and begin heating, the solid metallic of heating valve body 1 inside is to liquid, and then valve is in opening state.The opening and closing of valve are controlled according to the fusing point of controlled metal voluntarily by valve body 1 internal measurement device 4.Repeat said process and can realize the automatic control that pipeline valve is opened or closed under high temperature (300 °～800 ℃) condition.
Each parts all adopts welding to connect in the valve body 1, and Liquid sealing valve adopts pressure type pure metal seal ring 13 to be connected with upper flange 12 by lower flange 7 with other pipe-line equipment, has guaranteed valve and the pipeline sealing under high temperature condition.Valve opening is when closing, and valve body 1 is in the static sealing state all the time, prevents from the valve that reactive metal contact with ambient air the possible of chemical reaction taken place under high temperature condition.
The utility model is owing to adopt the said structure design, and compactness rational in infrastructure is easy and simple to handle, can realize the automation control of overall process heating and cooling, guarantees the safe and stable operation in the high activity metal refining process.
