Blockage-proof and leakage-proof angular fused salt regulating valve

Abstract

The invention discloses an anti-blocking and anti-leakage molten salt angular regulating valve, which comprises a valve body, a valve core, a valve stem, a valve cover, a sealing gasket, a bellows assembly, a sealing packing, a packing gland, a thermal insulation jacket and a fastening The valve body is an integral angular valve body, and its inlet and outlet channels are in the shape of a Venturi tube. The upper part of the outlet channel of the valve body is directly processed with a sealing cone that is suitable for sealing with the valve core. The valve cover is fixed A bellows assembly is installed in the upper end of the valve body and the inner cavity of the bonnet. The upper end of the bellows assembly is welded to a proper position in the middle of the valve stem. The sealing gasket is a 316L toothed gasket. Insulation jackets are added. The beneficial effect is that the flow path of the valve cavity is smooth, the inner cavity has no dead angle, good self-cleaning performance, excellent corrosion resistance, and the easy-to-solidify crystalline medium is not easy to deposit and block, especially suitable for industrial molten salt and other easy-to-solidify, crystalline medium working conditions. , The product has a long service life.

Description

technical field [0001] The invention relates to a regulating valve, in particular to an anti-blocking and anti-leakage molten salt angular regulating valve. Background technique [0002] Because of its compact structure and low flow resistance, the angle regulating valve is especially beneficial to the regulation of fluids with high viscosity, suspended solids and granular substances, so it is widely used in pipeline systems in chemical, metallurgical, petroleum and other industries. [0003] Molten salt is a kind of industrial salt that is solid at room temperature and molten liquid when the temperature rises. It is a common industrial medium widely used in modern chemical and pharmaceutical industries because of its strong corrosiveness, high concentration, It is easy to crystallize and solidify, and it is easy to cause deposition, jamming, poor circulation and other faults in the pipeline, especially the inner cavity of the valve. It cannot meet the technical requirements...

Problems solved by technology

[0003] Molten salt is a kind of industrial salt that is solid at room temperature and molten liquid when the temperature rises. It is a common industrial medium widely used in modern chemical and pharmaceutical industries because of its strong corrosiveness, high concentration, It is easy to crystallize and solidify, and it is easy to cause deposition, jamming, poor circulation and other faults in the pipeline, especially the inner cavity of the valve. It cannot meet the technical requirements for the adjustment and control of process parameters such as flow and pressure, and often affects the normal operation of process equipment. For safe operation, it is urgent to solve the technical problems of corrosion resistance, non-jamming and long service life of such valves
