KHB内螺纹高压球阀用于液压机械设备 液压开关 天然气 等。高压球阀问世于20世纪50年代,随着科学技术的飞速发展,生产工艺及产品结构的的不断改进,在短短的40年时间里,已迅速发展成为一种主要的阀类。在西方国家工业发达的国家,高压球阀的使用正在逐年不断的上升,在我国, KHB内螺纹高压球阀被广泛的应用在石油炼制、长输管线、化工、造纸、制药、水利、电力、市政、钢铁等行业,在国民经济中占有举足轻重的地位。
KHB内螺纹高压球阀主要用于截断或接通管路中的介质,亦可用于流体的调节与控制,其中硬密封V型球阀其V型球芯与堆焊硬质合金的金属阀座之间具有很强的剪切力,特别适用于含纤维、微小固体颗料等介质。而多通球阀在管道上不仅可灵活控制介质的合流、分流、及流向的切换,同时也可关闭任一通道而使另外两个通道相连。本类阀门在管道中一般应当水平安装。
KHB内螺纹高压球阀它具有旋转90度的动作,旋塞体为球体,有圆形通孔或通道通过其轴线。球阀在管路中主要用来做切断、分配和改变介质的流动方向,它只需要用旋转90度的操作和很小的转动力矩就能关闭严密。球阀适宜做开关、切断阀使用,但近来的发展已将球阀设计成使它具有节流和控制流量之用,如V型球阀。
KHB内螺纹高压球阀的主要特点是本身结构紧凑,密封稳定,结构简单,维修方便,密封面与球面常在闭合状态,不易被介质冲蚀,易于操作和维修,适用于水、溶剂、酸和天然气等一般工作介质,而且还适用于工作条件恶劣的介质,如氧气、过氧化氢、甲烷和乙烯等,在各行业得到广泛的应用。球阀阀体可以是整体的,也可以是组合式的。
KHB内螺纹高压球阀产品概述

Product Overview of KHB Female - threaded High - pressure Ball Valve
The KHB female - threaded high - pressure ball valve is a kind of valve used to control the flow cut - off of oil in hydraulic pipelines, featuring high - pressure resistance reliable sealing. The product overview is as follows :
- Pressure Caliber: The pressure range is usually between 1.6MPa 50MPa, the product caliber is DN15 - DN50 .
- Structural Design: It adopts a female - threaded connection mode, which is convenient for installation. The valve stem adopts a lower - mounted structure with back - seal. When the valve cavity is under abnormal pressure rise, the valve stem will be impacted. A 90° switch positioning mechanism can be set, a lock can be added as required to prevent misoperation .
- Material Selection: The valve body material is generally steel, stainless steel, etc. The ball material can be steel, brass stainless steel, which can adapt to different media working conditions. The sealing parts usually use NBR, fluororubber, etc., which have good sealing performance corrosion resistance .
- Working Principle: The valve is opened closed by rotating the valve core. It is generally manually operated, the handle can be rotated 90° to achieve full - open full - close .
- Performance Advantages: It has the characteristics of small flow resistance loss, reliable sealing performance convenient operation. The main body of some products is forged by high - pressure impact, the shell is strengthened, with high strength good impact resistance .
- Scope of Application: The applicable media include water, oil, gas, nitric acid, acetic acid, etc. The working temperature range is generally - 10℃ - + 80℃, the special model can reach 300℃ .
