HVH 黑水閥閥芯采用上導向結構，閥體流道呈帶斜面的球形空腔結構，閥座設計遵循文丘里加速原理，閥芯和閥座采用噴焊或整體燒結硬質合金，達到防沖刷、耐磨損的作用，該產品具有防堆堵，抗沖蝕，大流通能力，可調范圍廣等特點。主要適用于控制含有硬質顆粒的多相流體如煤漿水等。
調節閥配用薄膜式和氣缸活塞執行機構，其結構緊湊，輸出力大。
產品符合GB/T4213-2008標準。
Black Water Valve
HVH Black water valve has a top-guided valve plug, and a flow passage with the beveled global cavity structure. The design of valve seat follows Venturi Acceleration Principle. The plug and seat are spray welded or integral sintered carbides to prevent erosion and wearing. This product features blocking prohibition, anti-erosion, and allows a large flow capacity, wide rangeability. It is applicable to control multiphase fluid containing hard particles, as coal slurry .etc.
The actuator integrated with simplest mechanisms utilizes a compact yet powerful diaphragm actuator loaded with multiple springs or a cylinder.
This product complies with the GB/T4213-92 standards.
