Description
Technical field
The invention belongs to the heating high temperature valve on the magnesium method titanium sponge production inverted U reduction distillation associating stove connection passageway.
Background technique
Magnesium method reduction distillation is produced in the titanium sponge technology, owing to reduce, distill and carry out in same reactor heating, is connected with the parallel drainer that is provided with in the distillation stage, therefore is called the inverted U reduction distillation and unites stove.Evaporating kettle that used reactor, the still-process of reduction process is used and the condenser of accepting distillation magnesium, magnesium chloride are the tank body that same specification can be exchanged use.For the key of finishing reduction, distillation, separation, crystallization Joint Production is by pipeline and valve will also steam reactor and condenser is connected to become joint production, so that in reduction process,, in still-process, must pass through the valve opening pipeline by the valve closing pipeline.Because still-process needs excess metal magnesium and the remaining magnesium chloride in the titanium sponge after the separated reduction under the high temperature about 1000 ℃, so valve and pipeline must guarantee at high temperature to work, and could guarantee magnesium metal and not condensation of magnesium chloride blocking pipeline.And the valve rod of existing valve is non-cooling structure, is not closed completely under the condition of high temperature, has gas leak phenomenon.The heating equipment of valve and pipeline is to adopt hanging structure to arrange electric heating wire on refractory piece, and so easy generation electric heating wire goes out the groove phenomenon and influences normally carrying out of production.
Summary of the invention
In order to overcome the defective that existing valve exists, following technological scheme is proposed.A kind of heating high temperature valve, its special way is in the valve body of three-port structure ring-shaped valve seats to be installed, at the valve flange of the upper end of valve body mounting strap cooling jacket, valve rod and driving mechanism all are installed on the flange bracket, link to each other with valve flange by flange bracket then.So-called flange bracket is by support upper and lower two flanges to be formed by connecting.The water-cooled leading screw is installed in the flange bracket, the water-cooled leading screw is hemispheric valve rod by valve rod connection joint with its lower end and links to each other, the bottom of valve rod flexibly connects the flap lid, the flap lid links to each other with valve petal body, it is conical that the surface that valve petal body contacts with valve seat is, the internal surface of valve petal body is concave spherical surface, and between the hemisphere face of valve rod lower end certain interval is arranged, be provided with cooling water pipeline in the water-cooled leading screw, the outer surface of upper of water-cooled leading screw has longitudinal fluting, upper side at support is equipped with the locating stud that matches with this longitudinal fluting, the upper end of water-cooled leading screw links to each other with handwheel, and the water-cooled leading screw can only be along the locating stud lifting when rotation hand wheel.In the lower flange flange of flange bracket, be provided with seal ring and cooling jacket; High-alumina refractory spare is installed around valve body; at high-alumina refractory spare internal surface reciprocative slot is set, wherein arranges electric heating wire, the A/F of groove is less than the screw diameter of electric heating wire; there is containment vessel the outside of high-alumina refractory spare, and the outer surface of containment vessel is provided with wiring terminal and temperature measuring hole.
Owing to around the valve body of this heating high temperature valve high-alumina refractory spare and electric heating wire are housed, can heat valve, valve is worked under the condition of high temperature about 1000 ℃, guarantee magnesium metal and not condensation of magnesium chloride obstruction passageway in still-process.Simultaneously owing to be provided with cooling jacket at valve flange, flange bracket place, inside at the water-cooled leading screw is provided with cooling water pipeline, can guarantee that like this drive part is near room temperature, be convenient to operator's rotation hand wheel, drive the water-cooled leading screw, valve rod connects joint, valve rod and flap lifting, realize valve opening or close.Because gapped between the internal surface of valve petal body and the lower end hemisphere face of valve rod, like this, even there is deviation at valve rod center and valve seat center, flap also can be with respect to valve seat automatic straightening center when descending, the throttle down with the linear sealing of valve seat.Owing near the seal ring cooling jacket is arranged, guarantees that sealing is reliable, all non-leakage in vacuum or state of rest.Because flap is to link to each other with valve body by flange with driving mechanism, be convenient to the installation or removal maintenance like this, also be convenient to the change of functions of the equipments, promptly when equipment uses as condenser, with flange bracket and driving mechanism dismounting (adding a cover blind plate at the valve flange place shuts), only stay valve body and heating part; And when equipment as reduction or during distillation reactor, flange bracket and driving mechanism can be installed on the valve flange, promptly constitute complete heating high temperature valve.
This heating high temperature valve is installed in the equipment that the magnesium method is produced titanium sponge---on the connection passageway of inverted U-shaped reduction distillation associating stove, so that throttle down when reduction reaction, and in still-process, open valve, and valve and pipeline are under the condition of high temperature, guarantee magnesium metal in the titanium sponge and not condensation of magnesium chloride blocking pipeline after reducing.
