进口内外螺纹针型阀，仪表阀性能参数 Performance parameter
内外螺纹针型阀通常入口为外螺纹,出口为内螺纹或者是M20X1.5,是一种可以精确调整的阀门,通常与压力表配合使用,是仪表测量管路系统中作开启或切断管路的开关阀 RETZ The internal and external thread needle valve usually has an external thread at the inlet and an internal thread or M20X1.5 at the outlet. It is a valve that can be accurately adjusted. It is usually used in conjunction with the pressure gauge. It is an on-off valve used to open or shut off the pipeline in the instrument measurement pipeline system
结构特征： 锥面密封,活动阀瓣 Structural features: cone seal, movable valve disc
