A self-cleaning pneumatic valve

Abstract

The invention discloses a self-cleaning type pneumatic valve. The self-cleaning type pneumatic valve comprises a base, a valve body and a pneumatic device. The valve body is mounted on a base, and theupper end face of the valve body is provided with the pneumatic device. The self-cleaning type pneumatic valve has the advantages of being simple in structure, precise in control and good in cleaningeffect. The base, the valve body and the pneumatic device are combined to conduct throttle control over a fused salt pipe; the flow of the fused salt pipe can be controlled conveniently through a pneumatic valve according to the production need; meanwhile, a cleaning structure is arranged on a valve element, and fused salt liquid residues on the valve element can be cleared through compressed airby means of the cleaning structure arranged on the valve element; the problem that the valve elements deforms when being heated, and jamming occurs in the switching-on and switching-off processes, sothat precise control cannot be achieved conveniently is prevented; meanwhile, normal conveying of fused salt liquid can be controlled precisely, and normal circulation of the fused salt liquid is guaranteed; and the production efficiency can be improved conveniently, and the production cost can be lowered conveniently.

Description

technical field [0001] The invention relates to the technical field of pneumatic valves, in particular to a self-cleaning pneumatic valve. Background technique [0002] Pneumatic valves are valves driven by compressed air. When purchasing pneumatic valves, it is not perfect in the current market economic environment to only specify the specifications, categories, and working pressure to meet the procurement requirements. Because of the competition of products, pneumatic valve manufacturers carry out different innovations under the concept of unified design of pneumatic valves, forming their own corporate standards and product personalities. Molten salts, melts formed after melting salts, such as alkali Melts of metals, alkaline earth metal halides, nitrates, and sulfates. Molten salt is a molten body composed of metal cations and non-metal anions. Put the molten salt into the molten salt tank and heat it directly to melt, or add a small amount of water to the molten salt a...
