一、軟密封對夾式V型球閥產品概述

V型對夾球閥具有一個V型閥體，即使在小流量或高粘度介質的情況下，也可在整個量程范圍內，保證控制的精確性；

二、軟密封對夾式V型球閥主要技術參數和性能

 三、產品特點

（1）不帶任何管接頭的整體式閥體，因此不受管道或螺栓應力影響，并且由于閥體無任何管接頭，故耐壓殼體不會受壓力“突變”的影響；

（2）具有一個V型閥體，即使在小流量或高粘度介質的情況下，也可在整個量程范圍內，保證控制的精確性；

（3）防漏耐用的閥座在其外徑處襯有帶不銹鋼內芯PTFE杯形或是O型密封圈，閥座用截面較大的鎢鈷硬質合金制成，通過一個合金的波紋彈簧進一步增強了閥座的結構；

（4）當法蘭V型球閥關閉時，V型缺口與閥座之間產生楔形剪切作用，并既具有自潔功能又可防止球芯卡死，手動V型球閥特別適用于管線結垢凍結或含有纖維和顆粒固體場合。

四、 缺球工藝處理 1、表面鍍硬鉻：球體表面鍍硬鉻，常用普通介質硬密封工藝 2、表面噴焊司太立合金：腐蝕性介質常用工藝 3、表面噴碳化鎢：固體顆粒性介質及要求長壽命工況 4、表面離子氮化：一般固體顆粒介質 5、小流量缺球：DN25以內要求精確調節流量的普通介質。
