(BS)进口英标隔膜阀 主要性能 Main performance

BS英标隔膜阀的启闭件是一块膜片，膜片是一种富有弹性的材料，用螺栓连接在阀杆上,操作时上下移动，当膜片上升时阀打开，当膜片下降时，阀关闭，隔膜阀适用于开关及节流之用 RETZ opening and closing part of BS British standard diaphragm valve is a diaphragm. The diaphragm is a kind of elastic material. It is bolted to the valve stem and moves up and down during operation. When the diaphragm rises, the valve opens. When the diaphragm falls, the valve closes. The diaphragm valve is suitable for switching and throttling.

特点∶ Performance characteristics

1.气密好，无外部泄漏 Good air tightness and no external leakage

阀体与盖被中间隔膜隔开，使得隔膜上方的阀盖、阀杆等零件不受介质侵蚀。而且无外部泄漏或外界空气进入污染流体 The valve body and cover are separated by an intermediate diaphragm, so that the bonnet, valve stem and other parts above the diaphragm are not corroded by the medium. And there is no external leakage or outside air entering the contaminated fluid

2.阀座零泄漏 Zero leakage of valve seat

可挠性隔膜将流体隔断，因此阀座无泄漏  The flexible diaphragm blocks the fluid, so the valve seat has no leakage

采用橡胶隔膜时，即使流体内有些异物夹杂也能完全切断 When using rubber diaphragm, even if there are some foreign matters in the fluid, it can be completely cut off

3.耐蚀性、耐化学性优异 Excellent corrosion resistance and chemical resistance

通过橡胶、氟树脂等各种衬里阀体和丰富的隔膜材料相组合，可制造适合各种流体规格的阀，性价比优于特殊合金类材料 Through the combination of rubber, fluororesin and other lining valve bodies and abundant diaphragm materials, valves suitable for various fluid specifications can be manufactured, and the cost performance is better than that of special alloy materials

4..保养性优异 Excellent maintenance

采用“驱动部”、“隔膜”、“阀体”的三单元方式，拆解和装配方便 The three unit mode of "drive part", "diaphragm" and "valve body" is adopted, which makes disassembly and assembly convenient

采用顶部入口结构，因此无需将阀从管道上拆下，只要将阀体和阀盖的紧固螺栓和螺母卸下即可更换隔膜 The top inlet structure is adopted, so it is unnecessary to remove the valve from the pipeline. The diaphragm can be replaced by removing the fastening bolts and nuts of the valve body and bonnet

各单元具有兼容性，手动阀也能方便地改为自动化等方式  Each unit has compatibility, and manual valves can be easily changed to automation
