The advantages and disadvantages of insulation by the pneumatic valve

insulation by the pneumatic valve, is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other kinds of systems, with flow of high viscosity medium will under normal temperature solidification, BJW dc is jacketed heat preservation by pneumatic valve insulation between the two flanges of set of welding in the pneumatic valve, pneumatic valve at the bottom of the profile, set the heat preservation jacket two connectors. Dc insulation by the pneumatic valve is especially suitable for chemical industry, chemical fertilizer pipe road, jacketed connotation into the steam can prevent the crystallization medium. Thermal insulation by the pneumatic valve is widely used in petroleum, chemical, metallurgical, pharmaceutical and other kinds of systems.
the advantages of insulation by the pneumatic valve:
, simple structure, manufacture and maintenance more convenient.
, small work schedule, opening and closing time is short.
, good sealing, small friction between the sealing surface, long service life.
heat preservation by pneumatic valve disadvantages:
and fluid resistance is big, opening and closing the required force is larger.
, does not apply to take larger particles, viscosity, easy to coking of the medium.
and poor regulation performance.
