電動V型對夾球閥產品概述

本公司生產的電動V型對夾球閥，由電子式電動執行機構和V型球閥組成，是一種由V型切口球面閥板在小開度范圍內貼著密封面旋轉而控制流體的角行程調節閥。V型切口球面板在增大調節比的同時，在截流時對密封環還有剪切作用，因此適用于要求大調節比的控制系統，以及對含纖維質流體、料漿類流體的控制。適用于兩位切斷、調節的場合，采用一體化結構，電動執行機構內置伺服系統，輸入4-20mA控制信號或1-5VDC及220VAC電源即可控制運轉。具有連線簡單，結構緊湊、尺寸小、重量輕、阻力小、動作穩定可靠等優點。廣泛應用于石油、化工、電力、冶金、鋼鐵、造紙、醫藥、食品、紡織、輕工等行業。

主要特點

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、當閥門關閉時，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，特別適用于管線結垢凍結或含有纖維和顆粒固體場合。
