What are the commonly used materials for thermal insulation of cast basalt valves?

2021-09-03 05:03:22

The cast basalt valve, also known as the shut-off valve, is a forced sealing valve. Its opening and closing part is a plug-shaped valve disc, which is sealed with a flat or sea cone surface, and the valve disc moves linearly along the center line of the valve seat. Cast basalt valve is a common valve, which can be used to control the flow of various fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Due to the relatively short opening or closing stroke of the valve stem, this valve has a very reliable cutting function. The change of the valve seat hole pattern is directly proportional to the stroke of the valve disc, which is suitable for cutting or adjustment and throttling. Should industrial thermal insulation and cast basalt valve thermal insulation materials be used? The traditional thermal insulation method cannot be disassembled at one time. The use of thermal insulation materials for detachable ball valves can not only meet the thermal insulation requirements of the equipment, but also meet the detachability of the equipment, which is convenient for equipment maintenance. The products can be used for many times, and the utilization rate of thermal insulation sleeve can be improved. The common insulating materials of cast basalt valves are as follows: 1. Glass fiber felt. Glass fiber felt is a plate product made of continuous precursor or short cut precursor under the action of chemical binder or machinery. It is a kind of thermal insulation material with reasonable structure and good performance. It has good high temperature resistance and chemical stability. It is suitable for thermal insulation of high-temperature equipment, valves and pipelines of various heat sources (coal, electricity, oil and gas). 2. Ceramic fiber blanket. It is also called aluminum silicate fiber blanket, because one of its main components is alumina, which is the main component of ceramic fiber blanket, so it is called ceramic fiber blanket. Ceramic fiber blanket is mainly divided into ceramic fiber injection blanket and ceramic fiber silk carpet. Ceramic fiber silk carpet is mainly used as thermal insulation material for ball valve because of its long fiber length and low thermal conductivity. 3. aerogel felt. Aerogel felt is a flexible insulation felt made of carbon nanoscale or metal aerogel and made of carbon fiber or ceramic glass fiber cotton or pre oxidized fiber felt. It has the characteristics of low thermal conductivity, low tensile strength and low compressive strength. It belongs to a new type of thermal insulation material for ball valves.
