進(jìn)口V型球閥德國洛克品牌原裝

 

進(jìn)口V型球閥結(jié)構(gòu)特點(diǎn)：

1、V型球閥|V型球心閥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、V型球閥|V型球心閥具有一個(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、V型球閥|V型球心閥當(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，特別適用于高粘度、懸浮液、紙漿等不干凈、含纖維介質(zhì)場合。

進(jìn)口V型球閥工作原理：

這種球閥屬于固定球閥，也是單閥座密封球閥，調(diào)節(jié)性能是球閥中*的，流量特性是等百分比的，可調(diào)比達(dá)100:1。它的V型切口與金屬閥座之間具有剪切作用，特別適合含纖維、微小固體顆粒、料漿等介質(zhì)。球閥它具有相同的旋轉(zhuǎn)90度的動(dòng)作，不同的是旋塞體是球體，有圓形通孔或通道通過其軸線。球閥在管路中主要用來做切斷、分配和改變介質(zhì)的流動(dòng)方向，它只需要用旋轉(zhuǎn)90度的操作和很小的轉(zhuǎn)動(dòng)力矩就能關(guān)閉嚴(yán)密。

Working principle of imported V-type ball valve:
This kind of ball valve belongs to fixed ball valve and single seat sealed ball valve. Its regulating performance is the best among the ball valves. Its flow characteristic is equal percentage and its adjustable ratio is 100:1. Its V-notch has shear action with metal valve seat, which is especially suitable for medium containing fiber, micro solid particles, slurry and so on. The ball valve has the same action of rotating 90 degrees, but the difference is that the cock body is a ball, with a circular through hole or channel through its axis. Ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small torque to close tightly.

進(jìn)口V型球閥產(chǎn)品簡介：

德國洛克《DE LOCKE》進(jìn)口V型球閥球芯帶有Ｖ型結(jié)構(gòu)，閥芯是1/4球殼，開有V型缺口，流通能力大，可調(diào)范圍大、具有剪切力，能關(guān)閉嚴(yán)密等特點(diǎn)，特別適用于流體物質(zhì)帶纖維狀的工況。 一般情況下V型球閥都是單密封球閥。不適合用來雙向使用。

Introduction of imported V-type ball valve products:
The ball core of V-type ball valve imported from German Locke has V-type structure. The valve core is 1 / 4 spherical shell with V-type notch. It has the characteristics of large flow capacity, large adjustable range, shear force and tight closing. It is especially suitable for the working condition of fluid material with fibrous shape. In general, V-type ball valves are single seal ball valves. Not suitable for two-way use.
