LNG special low temperature valve / Product

Product Name: Stainless steel low temperature double card sleeve ball valve

Model: Q91F-320R

Caliber: DW6-DW80mm

Pressure: 1.0-42.0MPa

Material: stainless steel, carbon steel

Product introduction

Zhongli stainless steel low temperature double card sleeve ball valve-is mainly a special high pressure ball valve developed for the use of medium for LNG. It can replace imported ball valves, and can be used for card sleeves and welded pipes (welding is recommended for large calibers). Under the working condition of ~ -196 ℃, the switch can be guaranteed more than 10,000 times, and seals can be replaced, which increases the service life and reduces user costs.

-主要是针对使用介质为 LNG 而开发研究的特殊高压球阀,能够代替进口球阀,并可以卡套和焊管双用(大口径建议选用焊接),在低温 -80℃~-196℃的工况下均保证开关万次以上,并可换密封件,增加使用寿命减少用户成本。 Zhongli stainless steel low temperature double card sleeve ball valve -It is mainly a special high pressure ball valve developed for the use of medium for LNG . It can replace imported ball valves and can be used for both sleeves and welded pipes (large diameter is recommended for welding). Under the working conditions of ℃ ~ -196 ℃, the switch can be guaranteed more than 10,000 times, and the seals can be replaced to increase the service life and reduce user costs.

Basic parameters of stainless steel low temperature double card sleeve ball valve:

1.0MPa~42.0MPa Nominal pressure: 1.0MPa ~ 42.0MPa

DN6~DN80mm Nominal diameter: DN6 ~ DN80mm

-80℃~-196℃ Applicable temperature: -80 ℃ ~ -196 ℃

:卡套、螺纹、法兰等 Connection : ferrule, thread, flange, etc.

LNG天然气制造材料:碳钢、不锈钢、1Cr18Ni9Ti﹑304﹑316、316L Applicable medium: LNG natural gas manufacturing materials: carbon steel, stainless steel, 1Cr18Ni9Ti, 304, 316, 316L

Principle of stainless steel low temperature double card sleeve ball valve:

150.0MPa。 Stainless steel low temperature double card sleeve ball valve, the valve body is made of high pressure impact forging, the shell is strengthened, and the test pressure can reach 150.0MPa. Applicable to the opening and closing device that controls the connection or cutoff of pipeline medium under various pressures, temperatures and media of medium and small diameter pipelines; the ball is pressed against the valve seat at the outlet end by the medium pressure, and its use pressure and diameter Limited by certain limits. With 90 ° drive, the switch is convenient and fast, and can be quickly opened and closed.

1. Through threaded mechanical advancement, the ferrule nut moves forward to push the rear ferrule forward, while the rear ferrule pushes the front ferrule forward.

,可以输送浆液及固体颗粒等介质. 2.The stainless steel low temperature double card sleeve ball valve channel is smooth and easy to clean the pipeline.It can transport slurry and solid particles and other media.

3.Use PTFE (Teflon) and other materials as the seal, which has good lubricity and elasticity, small friction with the ball, and long service life.

4.Opening and closing quickly, just turn the sphere 90 ° when opening and closing, convenient and fast.

,全开时球体通道、阀体通道和连接管道的截面积相等,并且成直线相通 ,介质流过球阀,相当于流过一段直通的管子,在各类阀门中球阀的流体阻力很小。 5.The stainless steel low temperature double card sleeve ball valve has small fluid resistance . When fully opened, the cross-sectional areas of the ball channel, the valve channel and the connecting pipe are equal, and they communicate in a straight line. Ball valves in all types of valves have very little fluid resistance .

6, stainless steel low temperature double card sleeve ball valve is widely used in water treatment equipment, chemical equipment, petrochemical equipment, petroleum equipment, papermaking equipment, mining equipment, etc., advance, the sleeve nut moves forward to push the rear ferrule forward, while the rear card The sleeve pushes the front card sleeve forward.

特点: Features of stainless steel low temperature double card sleeve ball valve :

1) For opening-cutting of the flow path ;

2) No adjustment capability, if the system needs to achieve flow adjustment, it must be completed by a series of regulating valves ;

20.6MPa 3) The working pressure of stainless steel low temperature double card sleeve ball valve can reach 20.6MPa ;

4) The standard form of stainless steel low temperature double card sleeve ball valve is horizontal valve, and angle valve can also be selected;

5) Can be panel mounted .
