進(jìn)口V型球閥是一種芯閥座采用金屬，或金屬對(duì)聚四氟乙烯密封配合的旋轉(zhuǎn)球閥，它將球閥和蝶閥的控制特性結(jié)合成一體,既可用作控制調(diào)節(jié)閥，又可作關(guān)斷切斷閥。其主要特點(diǎn)是：
（１）不帶任何管接頭的整體式閥體，因此不受管道或螺栓應(yīng)力影響，并且由于閥體無任何管接頭，故耐壓殼體不會(huì)受壓力“突變"的影響；
（２）具有一個(gè)Ｖ型閥體，即使在小流量或高粘度介質(zhì)的情況下，也可在整個(gè)量程范圍內(nèi)，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(nèi)芯ＰＴＦＥ杯形或是Ｏ型密封圈，閥座用截面較大的鎢鈷硬質(zhì)合金制成，通過一個(gè)合金的波紋彈簧進(jìn)一步增強(qiáng)了閥座的結(jié)構(gòu)；
（４）當(dāng)閥門關(guān)閉時(shí)，Ｖ型缺口與閥座之間產(chǎn)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(jié)垢凍結(jié)或含有纖維和顆粒固體場合。
適用于高粘度、懸浮液、紙漿等不干凈、含纖維介質(zhì)場合。采用直連方式與執(zhí)行機(jī)構(gòu)連接，具有結(jié)構(gòu)緊湊、尺寸小、重量輕、阻力小、動(dòng)作穩(wěn)定可靠等優(yōu)點(diǎn)。執(zhí)行機(jī)構(gòu)根據(jù)用戶要求配置UNIC、PSQ、HQ、DHL等型號(hào)電子式電動(dòng)執(zhí)行機(jī)構(gòu)或GTX、AL等氣動(dòng)活塞式執(zhí)行機(jī)構(gòu)。 
Import V-ball valve seat of a core metal, or metal PTFE seal with rotating ball valve, it ball and butterfly valves control features combined into one, and both can be used as a control regulating valve, but alsofor off shut-off valve. Its main features are:
(1) without any pipe joint piece body without pipe or bolt stress, and because the body without any pipe joints, the pressure shell is not affected by the pressure "mutation" of the impact;
(2) has a V-shaped valve body, even in the case of small flow or high viscosity media, but also in the entire range to ensure the accuracy of the control;
(3) leakproof durability of the valve seat at its outer diameter, lined with stainless steel inner core PTFE cup-shaped or O-ring, the valve seat with a larger cross-section of the tungsten-cobalt cemented carbide by an alloy corrugated the spring further enhanced the seat structure;
(4) When the valve is closed, the V-notch between the valve seat wedge shearing, and both have a self-cleaning function and prevents the ball core stuck, especially suitable for pipeline scaling freeze or containing fibers and particles of solid occasions .
Applies to the high viscosity, suspensions, such as pulp is not clean, the fiber-containing media occasions. With Direct Connect connection with the executing agency, with a compact, small size, light weight, small resistance, stable and reliable action, etc.. Implementing agencies according to user requirements the model electronic electric actuators configure the UNIC PSQ, HQ, DHL or GTX, AL pneumatic piston actuator. |
