Heating high temperature valve and uses thereof

Abstract

A heating hi-temperature valve installed on the connection passage of an equipment, namely a reversed U-like reduction distilling combine furnace, for producing sponge titanium by magnesium method is provided, which comprises a valve body, a heater out the valve body and a valve clack. In the valve body, a circular valve seat is mounted, the valve clack is mounted in a support flange, and is connected with the valve body through a flange. The drive mechanism includes a handwheel, a water-cooled lead screw, a valve-rod connector, a valve rod and a valve clack. The outer surface of the valve clack is conic, is in linear contact with the circular valve seat, so as to guarantee reliable sealing. The heating hi-temperature valve can work under a high temperature up to 1000 centigrade, guarantee free closing, opening and reliable sealing. And as circulating cooling water is provided in the water-cooled lead screw, and cooling water jacket is provided in the flange for cooling the lead screw, the hand wheel is under room temperature, and is easy to operate.

Description

technical field [0001] The invention belongs to the heating high-temperature valve on the connecting corridor of an inverted U-shaped reducing distillation combined furnace for producing sponge titanium by magnesium method. Background technique [0002] In the production process of sponge titanium by magnesium reduction distillation, since the reduction and distillation are carried out in the same heating reactor, it is connected with the parallel condensation tank in the distillation stage, so it is called an inverted U-shaped reduction distillation combined furnace. The reactor used in the reduction process, the evaporator used in the distillation process and the condenser receiving distilled magnesium and magnesium chloride are all interchangeable tank bodies of the same specification. The key to complete the joint production of reduction, distillation, separation and crystallization is to connect the distillation reactor and condenser to form a joint production device th...

Problems solved by technology

However, the valve stem of the existing valve is a non-cooling structure, which is not tightly closed under high temperature conditions, and there is an air leakage phenomenon.

The heating devices for valves and pipelines are installed on the refractory parts with a hanging structure to arrange the heating wires, which is easy to cause the heating wires to go out of the groove and affect the normal production
