高溫高中壓截止閥
截止閥（Globe Valve）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(zhuǎn)桿式（手輪與閥桿一起旋轉(zhuǎn)升降，螺母設(shè)在閥體上）。截止閥只適用于全開和全關(guān)，不允許作調(diào)節(jié)和節(jié)流。

結(jié)構(gòu)特點與用途：
Strucure features and usages:
- 全關(guān)時手輪按順時針方向旋轉(zhuǎn)；
- 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.
