Recently, Jinbin valve workshop completed a high-pressure goggle valve production task, specifications are DN100, DN200, the working pressure is PN15 and PN25, the material is Q235B, the use of silicone rubber seal, the working medium is flue gas, blast furnace gas. After the inspection by the technicians of the workshop, this batch of high-pressure goggle valves have been packed and is ready to be sent to Russia.

So, what are the characteristics and advantages of high pressure sliding plate goggle valve?

High pressure energy

The nominal pressure design of PN16 (1.6MPa) and PN25 (2.5MPa) can be adapted to the high-pressure pipeline system. The diameter of DN100 and DN200 can meet the requirements of different flow media truncation, whether it is small and medium flow control or large diameter pipeline isolation, it can be stable pressure.

2. Reliable sealing performance

Precision sealing structure, with high quality sealing materials, even under high pressure conditions, can effectively block the leakage of the medium, to ensure the tightness of the pipeline system, to ensure production safety.

3. Superior material performance

The main body is made of Q235B carbon structural steel, which has good strength, toughness and processing properties, stable endurance, strong impact resistance, and can adapt to complex working conditions and extend the service life of the shaped blind valve.

4. Convenient operation and maintenance

Equipped with manual drive device, switch operation is simple and flexible, some models support remote control; Compact structure, small space, easy installation and disassembly, low maintenance cost.

The specific application scenario of high pressure goggle valve blast furnace

1. Petrochemical field: In high pressure pipelines such as crude oil transportation and chemical raw material processing, it is used for media isolation during equipment maintenance and pipeline segmentation to prevent the leakage of flammable and explosive media and ensure operation safety.

2. Power industry: It is suitable for high pressure systems such as steam pipelines in thermal power plants and circulating water pipelines in nuclear power plants to achieve medium truncation and equipment isolation and ensure system stability during maintenance or operation of power equipment.

3. Metallurgical industry: In the blast furnace gas transmission, oxygen/nitrogen pipeline and other scenarios, to cope with high temperature and high pressure conditions, complete the pipeline closure and media blocking, to meet the strict safety control needs in metallurgical production.

4. Gas transmission system: used for sectional control of urban high-pressure gas pipelines. During maintenance, blind valve is used to cut off air flow, avoid gas leakage, and ensure construction safety and reliability of urban gas supply.

With the characteristics of strong pressure, high seal and easy maintenance, this kind of high pressure blind valve has become the core equipment of medium truncation and safety isolation in industrial high pressure pipeline system.
