BJ45W direct heat preservation stop valve, direct heat preservation stop valve, stop valve

BJ45W Direct heat preservation globe Valve Product introduction:

Installed between the two flanges of the valve, the side and bottom of the valve are provided with two connecting ports of the thermal insulation jacket. It is suitable for the pipeline of chemical industry and fertilizer industry, and the steam content of the jacket can prevent the crystallization of the medium, which is widely used in various systems such as petroleum, chemical industry, metallurgy, pharmaceutical, etc., to transport high-viscosity media that will not solidify at normal temperature.

Product implementation standards:

one Design and manufacture according to GB12234-89 GB12234-89

2. The structure length is GB12221-89 GB12221-89

3. Flange size according to JB/T79-94 JB/779-94

4. Valve inspection and test according to GB13927

Product working principle:

According to the welding jacket between the two flanges of the Y-type stop valve, the side and bottom of the valve are provided with two connection ports of the thermal insulation jacket for injecting steam or other thermal insulation and cold media to ensure that the medium in the valve can work normally. It has good thermal insulation and cold protection characteristics, and can effectively reduce the heat loss of the medium in the pipeline. Integrated jacket structure design, more uniform heat preservation, cold protection, the jacket using carbon steel pipe welding than casting more solid pressure. Jacket, body outside welded with jacket nozzle, allow steam or cold water up to 1MPa.

BJ45W direct flow insulation globe valve design features:

1) Simple structure, unique appearance design.

2) The sealing surface is hardened to resist wear.

3) The valve neck bushing material has a low friction coefficient, greatly reducing torque and axial surface wear, and eliminating surface scrapes.

4) The valve cavity device is composed of two parts, which is conducive to quick disassembly and internal repair in place.

5) The structure of the inclined axis and the shape of the optimal flow channel, reduce the change of flow direction and reduce the number of depressurization.

6) Overall surface hardening of the seat: provides reliable closure and long seat life.

7) Threaded cover: prevent stuck and easy to install and disassemble.

8) Valve shaft packing device: The soft graphite of the ring permeated with carbon fiber cracks is used as packing for the best leak-proof and durable.

9) Reciprocating test 10000 times without fault, reliable performance to prevent external leakage.

It is suitable for the pipeline of chemical industry and fertilizer industry, and the steam content of the jacket can prevent the crystallization of the medium, which is widely used in various systems such as petroleum, chemical industry, metallurgy, pharmaceutical, etc., to transport high-viscosity media that will not solidify at normal temperature
