德國洛克進口電動V型調(diào)節(jié)球閥

一、進口電動V型調(diào)節(jié)球閥描述：

德國LOCKE洛克進口電動V型調(diào)節(jié)球閥是一種芯閥座采用金屬，或金屬對聚四氟乙烯密封配合的旋轉(zhuǎn)球閥，它將球閥和蝶閥的最佳控制特性結(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；LDRV型電動V型調(diào)節(jié)球閥為電動單元組合儀表中執(zhí)行單元，可實現(xiàn)比例調(diào)節(jié)，接收ON-OFF或4-20mAC或1-5VDC的信號進行比例動作的小型、堅固、高精度的電動執(zhí)行機構(gòu)，動作靈敏，并采用轉(zhuǎn)角直接指示和反饋，廣泛應(yīng)用于石油、化工、造紙、冶金、污水處理等行業(yè)，實現(xiàn)管道中介質(zhì)流量調(diào)節(jié)和切斷，以達到生產(chǎn)過程按一定的規(guī)范進行。

The electric V-type regulating ball valve imported from Germany locke is a rotary ball valve with metal core seat or metal to PTFE seal fit. It combines the best control characteristics of ball valve and butterfly valve, LDRV type electric V-type regulating ball valve is an executive unit in the combined instrument of electric unit, which can realize proportional adjustment and receive on-off or 4-20mac or 1-5vdc signal for proportional action. It is a small, solid and high-precision electric actuator with sensitive action, direct indication and feedback of angle, which is widely used in petroleum and chemical industry In the industry, papermaking, metallurgy, sewage treatment and other industries, the medium flow in the pipeline can be adjusted and cut off, so that the production process can be carried out according to certain specifications.

二、進口電動V型調(diào)節(jié)球閥主要參數(shù)：

三、進口電動V型調(diào)節(jié)球閥優(yōu)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(yīng)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(zhì)的情況下，也可在整個量程范圍內(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，通過一個合金的波紋彈簧進一步增強了閥座的結(jié)構(gòu)；

（４）當閥門關(guān)閉時，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)行機構(gòu)連接，具有結(jié)構(gòu)緊湊、尺寸小、重量輕、阻力小、動作穩(wěn)定可靠等優(yōu)點。

(1) The integral valve body without any pipe joint is not affected by pipe or bolt stress. Because the valve body has no pipe joint, the pressure shell will not be affected by pressure "mutation";

(2) It has a V-shaped valve body, which can ensure the accuracy of control in the whole range even in the case of small flow rate or high viscosity medium;

(3) The leakage proof and durable valve seat is lined with PTFE cup-shaped or O-ring with stainless steel inner core at its outer diameter. The valve seat is made of tungsten cobalt cemented carbide with large cross-section. The structure of the valve seat is further enhanced by an alloy corrugated spring;

(4) When the valve is closed, wedge shear action occurs between the V-notch and the valve seat, which not only has the function of self-cleaning, but also can prevent the ball core from sticking. It is especially suitable for pipeline scaling and freezing or containing fiber and particle solids. Suitable for high viscosity, suspension, pulp and other unclean, containing fiber media occasions. It has the advantages of compact structure, small size, light weight, small resistance, stable and reliable action.
