overview

As we all know, the urban pipe network in China is generally medium pressure transmission.The delivery pressure is generally

0.1-0.4mpa, and the gas pressure of direct fired equipment (gas boiler, direct fired medium pressure air conditioning unit, etc.) is generally 10-100kpa. Therefore, the company has developed a special pressure regulating (metering) box for such customers.

product characteristics

• this series of pressure regulating box is designed according to the characteristics of industrial gas (quick opening and closing, uninterrupted gas supply).
  The meter adopts two-way automatic switching to ensure uninterrupted gas supply.
  

• this series of pressure regulating box also has the characteristics of quick response, stable outlet pressure and high opening and closing accuracy of pressure regulating valve port under the condition of large flow range change.Can satisfy the work extremely
  Requirements for use of industrial users and Gongfu direct fired equipment.
  

• this series of pressure regulating box integrates filtering, pressure regulating, metering and other functions, with small floor area and low maintenance cost
  

• reasonable structure, perfect function, high reliability and good system coordination
  

• box material: carbon steel spray box, color steel box, stainless steel box

main structure

• 1+0(no bypass for pressure regulation of 1 circuit)
  

• 1+1(1 voltage regulation + 1 bypass)
  

• 2+0(no bypass for 2-way voltage regulation, one for use and one for standby)
  

• 2+1(2-way voltage regulation + 1-way bypass, one for use, one for standby and one for bypass)

main technical parameters

• Maximum inlet pressure: 0.2MPa, 0.4MPa, 0.8MPa, 1.6Mpa outlet pressure range: 1-30kpa, 30-100kpa, 100-150kpa, 150-200kpa
  

• 200-400kpa, 400-800kpa flow range: 100-20000nm / h3
  

• Voltage regulator: domestic main regulator, South Korea Huaying, Germany Elster, Germany echuang.
  

• Stabilization accuracy: AC ≤ 5% closing pressure: SG ≤ 10%
