(BS)進口英標(biāo)隔膜閥 主要性能 Main performance

BS英標(biāo)隔膜閥的啟閉件是一塊膜片，膜片是一種富有彈性的材料，用螺栓連接在閥桿上,操作時上下移動，當(dāng)膜片上升時閥打開，當(dāng)膜片下降時，閥關(guān)閉，隔膜閥適用于開關(guān)及節(jié)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.

特點∶ Performance characteristics

1.氣密好，無外部泄漏 Good air tightness and no external leakage

閥體與蓋被中間隔膜隔開，使得隔膜上方的閥蓋、閥桿等零件不受介質(zhì)侵蝕。而且無外部泄漏或外界空氣進入污染流體 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.閥座零泄漏 Zero leakage of valve seat

可撓性隔膜將流體隔斷，因此閥座無泄漏  The flexible diaphragm blocks the fluid, so the valve seat has no leakage

采用橡膠隔膜時，即使流體內(nèi)有些異物夾雜也能完全切斷 When using rubber diaphragm, even if there are some foreign matters in the fluid, it can be completely cut off

3.耐蝕性、耐化學(xué)性優(yōu)異 Excellent corrosion resistance and chemical resistance

通過橡膠、氟樹脂等各種襯里閥體和豐富的隔膜材料相組合，可制造適合各種流體規(guī)格的閥，性價比優(yōu)于特殊合金類材料 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..保養(yǎng)性優(yōu)異 Excellent maintenance

采用“驅(qū)動部”、“隔膜”、“閥體”的三單元方式，拆解和裝配方便 The three unit mode of "drive part", "diaphragm" and "valve body" is adopted, which makes disassembly and assembly convenient

采用頂部入口結(jié)構(gòu)，因此無需將閥從管道上拆下，只要將閥體和閥蓋的緊固螺栓和螺母卸下即可更換隔膜 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

各單元具有兼容性，手動閥也能方便地改為自動化等方式  Each unit has compatibility, and manual valves can be easily changed to automation
