Insulation jacket valve structure characteristics and working principle

Insulation jacket valve is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other systems, insulation jacket valve installed in the valve sleeve between the two flanges , the valve side, the bottom is provided with a jacket connector , The jacket can freely flow steam or other hot insulation medium, to ensure that the viscous medium can flow smoothly through the valve .

Insulation jacket valve for nominal pressure PN1.0 ~ 10.0MPa, Class150 ~ 600, JIS10K ~ 20K, operating temperature -29 ~ 425 ℃ (carbon steel), -40 ~ 500 ℃ (stainless steel) for opening and closing the pipeline , And can heat and prevent crystallization of the medium. Selection of different materials, respectively, for heavy oil, plastic, nitric acid, acetic acid, strong oxidizing media and urea and other media.

Insulation jacket valve structure

Insulation jacket valve Features:

Jacket welding installed in the valve between the two flanges, the valve side, the bottom of the jacket with a connection port. Connecting flange size than the same specifications of the ordinary valve connecting flange size one to two specifications, the same structure with the same length of the ordinary valve. The jacket can freely flow steam or other hot insulation medium, to ensure that the viscous medium can flow smoothly through the valve.

Insulation valve works:

Insulation valve has a good thermal insulation properties, and the valve diameter and diameter of the same, but can effectively reduce the pipeline medium heat loss. Has a good thermal insulation properties, while reducing the pipeline medium heat loss. Insulation valves in the petroleum, chemical, metallurgical, pharmaceutical and other systems are more applications, effectively reducing the heat loss of the pipeline medium, to prevent the crystallization medium, such as the appearance of solidification. Insulation valve is the role of high or low temperature conditions through the valve, the insulation material inside the valve insulation effect, so that the medium will not condense or stick in the valve body, so that the valve opening and closing to normal operation.

Insulation jacket valve standard:

Design and manufacture of standards: GB / T 12234

Structure length standard: GB / T

Connection flange standard: GB / T 9113

Pressure temperature grade: GB / T

Test test standards: GB / T

Insulation jacket valve parts materials and conditions:

Insulation valves and ordinary valves What is the difference:

Insulation valve and the difference between the ordinary valve is the insulation of the outer insulation interlayer insulation layer, there are two entrances and exits in the junction. You can use steam or hot oil as the insulation valve through the medium without temperature reduction and curing.

Shoe Polish

Shoe polish is a kind of product used to polish, repair leather shoes or boots, and strengthen their waterproof power, which can extend the life of shoes. Shoe polish is usually wax or paste. The utility model relates to a preparation for wiping the surface of leather shoes to make them clean and bright. It can be divided into liquid, emulsion, semi-solid and solid. The main component is wax.

Shoe polish is a substance used to shine and protect leather shoes. It can come in various forms such as paste, cream, or liquid and is typically made from a combination of wax, oil, and pigment. The polish is applied to the shoe using a brush or cloth and buffed to a shine. It helps to protect the leather from water damage, scuffs, and scratches, and can also restore the color of faded or worn-out shoes.

After applying shoe polish to the leather upper, the solvent evaporates, leaving a thin wax film, which can achieve the goals of waterproof, insect proof, shiny, protective leather, and enhancing aesthetics.
