鑫盛源内螺纹针型阀优点：

1、两截阀杆设计，上阀杆螺纹淡化工艺处理

2、下阀杆表经经滚压硬化处理上阀杆螺纹的润滑脂与系统介质隔离

3、无旋转的下阀杆垂直运动代替旋转升降，减少阀杆行程对填料的磨擦，手感更轻便

4、阀门在全开位置具有背密封功能

5、可选面板安装

6、可安装手柄或者手轮操作，稳固耐用多种颜色手柄可供选择

7、每只阀门在出厂前均按设计压力的1.1倍进行氮气密封测试,并按额定工作压力的1.5倍水压进行壳体强度测试

内螺纹针型阀

内螺纹针型阀是一种采用内螺纹连接方式的针型阀，主要用于对流体流量进行精密调节和截断，适用于小流量、高压的工况环境。其阀芯呈针状，与阀座形成紧密配合，密封性能稳定，能有效防止介质泄漏。

内螺纹针型阀阀体通常选用碳钢、不锈钢（如304、316）等材质，以适应水、油、蒸汽及部分腐蚀性介质的输送需求。内螺纹连接（如NPT、G、M等标准螺纹）具有结构紧凑、安装便捷的特点，无需额外法兰或管道配件，适合空间受限的管路系统。

内螺纹针型阀广泛应用于石油、化工、电力、冶金等行业的高压管道中，常作为压力表、流量计等仪表的控制阀门，或用于调节精密设备的介质流量。

The female thread needle valve is a type of needle valve with female thread connection, mainly used for precise regulation shut-off of fluid flow, suitable for small-flow high-pressure working conditions. Its valve core is needle-shaped, forming a tight fit with the valve seat, which provides excellent sealing performance can effectively prevent medium leakage.

The valve body is usually made of materials such as carbon steel, stainless steel (e.g., 304, 316), etc., to adapt to the transportation needs of water, oil, steam some corrosive media. The female thread connection (such as NPT, G, M other standard threads) features a compact structure convenient installation, without the need for additional flanges pipeline fittings, making it suitable for pipeline systems with limited space.

This valve is widely used in high-pressure pipelines in industries such as petroleum, chemical industry, electric power, metallurgy. It is often used as a control valve for instruments like pressure gauges flow meters, for regulating the medium flow of precision equipment.
