The structure of the thermal insulation valve insulation jacket is roughly the same, which is mainly composed of a thermal insulation layer and a thermal insulation shell. The thermal insulation layer is generally directly wrapped on the valve, and the thermal insulation shell is sleeved on the outer surface of the thermal insulation layer. The disadvantage is that the installation and disassembly are inconvenient; the heat insulation layer cannot be reused as it is, and the cost is high.

New valve insulation method: use flexible and detachable insulation cover, which adopts high and low temperature resistant, fireproof insulation materials;

It consists of three layers: inner lining, middle insulation layer and outer protective layer;

According to the specific shape of the pipeline or valve equipment and its use environment, it is made through a special process after careful design, surveying and mapping.

The advantages of this valve insulation method are:

1. The valve insulation sleeve is simple in structure, easy to install, easy to disassemble, and easy to maintain.

2. The high strength of the valve insulation cover can effectively protect the safety of the valve, reduce the corrosion and anti-condensation of the valve, and prolong the service life of the valve; it can be reused and has a long service life.

3. The appearance of the valve insulation cover is beautiful and clean, and the surface is scrub-resistant; it is non-polluting and completely harmless to people and the environment.

The valve insulation method can be widely used in thermal and refrigeration equipment and valve insulation on various valve bodies in petrochemical, textile printing and dyeing, electrical metallurgy, paper printing, biopharmaceuticals, food and beverage, marine locomotives, HVAC and other fields.
