高溫截止閥J41Y,上海滬工閥門制造有限公司截止閥
截止閥的啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運動。閥桿的運動形式，有升降桿式（閥桿升降，手輪不升降），也有升降旋轉桿式（手輪與閥桿一起旋轉升降，螺母設在閥體上）。截止閥只適用于全開和全關，不允許作調(diào)節(jié)和節(jié)流。
結構特點與用途：
Strucure features and usages:
全關時手輪按順時針方向旋轉；
可以安裝在管道的任何位置上，介質(zhì)從下往上流；
不銹鋼截止閥適用于各類腐蝕性介質(zhì)的管道上，有良好的防腐性和足夠的強度；
合金鋼截止閥適用于耐高溫的蒸汽、油品管道上，具有耐高溫特點。
When fully closed,the handwheel rotates clockwise.
Able to be mounted on any position of the pipeline,the medium flows from down to up.
Stainless steel made stop valve is of good anti-corrosive property and enough strength and suitable for various pipelines with corrosive medium.
Alloy steel made stop valve features high-temperature resistance,suitable for high-temperature steam and oil goods pipelines.
