進(jìn)口軌道球閥德國(guó)洛克品牌

進(jìn)口軌道球閥結(jié)構(gòu)特點(diǎn)：

1、無(wú)關(guān)無(wú)磨損:球體偏離閥座后再轉(zhuǎn)動(dòng)消除了閥座的磨擦，解決了傳統(tǒng)球閥、閘閥、旋塞閥的閥座磨損問(wèn)題。

2、單閥座設(shè)計(jì):軌道閥門(mén)的靜態(tài)單閥座能夠保障零泄露，避免了雙向閥座閥門(mén)的內(nèi)腔壓力升高的問(wèn)題。

3 流體特性:全通徑和縮徑閥門(mén)在開(kāi)位時(shí)都有很高的Cv值。提高泵了的系統(tǒng)效率，并且使腐蝕問(wèn)題降到了*程度。

4、頂裝式設(shè)計(jì):在系統(tǒng)泄壓后，可以在線檢查和維修，使維護(hù)簡(jiǎn)魚(yú)化。

5、雙閥桿導(dǎo)向銷:硬性閥桿導(dǎo)槽與導(dǎo)銷控制閥桿的升降和轉(zhuǎn)動(dòng)。

6、自清洗:當(dāng)閥芯傾離閥座時(shí)，流體沿密封面360度將一些外來(lái)的雜物沖洗干凈。

7、低扭矩操作:除特大尺寸外，其他尺寸的閥門(mén)均可配置小手輪而無(wú)需齒輪箱。因?yàn)檐壍篱y門(mén)密封面無(wú)摩擦，轉(zhuǎn)動(dòng)特別容易。

8、杭磨閥芯硬密封面:閥芯表面堆焊了一層硬質(zhì)拋光密封面，能夠在不損壞密封完整性的情況下滿足非?？量坦r的密封要求。

9、機(jī)械楔形密封:閥桿下端的斜面提供一個(gè)機(jī)械的楔緊力以保證持續(xù)的緊密封。

Structural features of imported orbital ball valve:

1. Irrelevant and wear-free: the ball deviates from the valve seat and then rotates to eliminate the friction of the valve seat, and solves the valve seat wear problem of the traditional ball valve, gate valve and plug valve.

2. Single seat design: the static single seat of rail valve can ensure zero leakage and avoid the problem of cavity pressure rise of double seat valve.

3 fluid characteristics: both full bore and reduced size valves have high CV values in open position. The efficiency of the pump system is improved and the corrosion problem is reduced to the degree of *.

4. Top mounted design: after the system is depressurized, online inspection and maintenance can be carried out to simplify the maintenance.

5. Double stem guide pin: rigid stem guide groove and guide pin control the lifting and rotation of the valve stem.

6. Self cleaning: when the valve core leans away from the valve seat, the fluid will flush some foreign debris along the sealing surface 360 degrees.

7. Low torque operation: except for extra large size, valves of other sizes can be equipped with small handwheels without gearbox. Because there is no friction on the sealing surface of rail valve, it is very easy to rotate.

8. Hard sealing surface of hangmo valve core: the surface of valve core is overlaid with a layer of hard polished sealing surface, which can meet the sealing requirements under very harsh working conditions without damaging the sealing integrity.

9. Mechanical wedge seal: the bevel at the lower end of the stem provides a mechanical wedge force to ensure continuous tight seal.

進(jìn)口軌道球閥工作原理：

順時(shí)針轉(zhuǎn)動(dòng)手輪，閥桿上設(shè)有準(zhǔn)確導(dǎo)向槽使球體順時(shí)針轉(zhuǎn)動(dòng)90度，在閥桿的楔臂作用下球體向前擺動(dòng)迫使球體密封面靠貼閥座密封面，達(dá)到密封效果。逆時(shí)針轉(zhuǎn)動(dòng)手輪使閥桿上升，球芯在閥桿楔臂和閥桿準(zhǔn)確導(dǎo)向槽的作用下，先離開(kāi)密封面(無(wú)摩擦)后球體逆時(shí)針轉(zhuǎn)動(dòng)90度，達(dá)到軌道球閥 的開(kāi)啟。

凸輪的原理使得閥球在旋轉(zhuǎn)中與閥座密封面脫離，旋轉(zhuǎn)到位后再將閥球推向閥座實(shí)現(xiàn)密封。當(dāng)閥門(mén)處于全開(kāi)位置時(shí)，瞬時(shí)針轉(zhuǎn)動(dòng)手輪，在閥桿螺母與止推軸承配合下，閥桿開(kāi)始下降并帶動(dòng)球體開(kāi)始旋轉(zhuǎn)。連接轉(zhuǎn)動(dòng)手輪，閥桿上的精密螺旋曲線槽軌道，與嵌于其內(nèi)的導(dǎo)向銷相互作用，帶動(dòng)球體隨閥桿不停地按順時(shí)針?lè)较蜣D(zhuǎn)動(dòng)。當(dāng)閥門(mén)將要關(guān)閉時(shí)，閥桿帶動(dòng)球體在與閥座密封面完全無(wú)摩擦的情況下旋轉(zhuǎn)了90°。繼續(xù)轉(zhuǎn)動(dòng)手輪，再次下降的閥桿通過(guò)閥桿下端的凸輪結(jié)構(gòu)機(jī)械地壓迫球體，使球體密封面與閥座密封面緊密接觸，從而達(dá)到密封的目的。軌道硬密封球閥處于全關(guān)位置時(shí)逆時(shí)針轉(zhuǎn)動(dòng)手輪，在閥桿螺母與止推軸承的配合下，閥桿開(kāi)始上升，并帶動(dòng)球體開(kāi)始旋轉(zhuǎn)，。連續(xù)轉(zhuǎn)動(dòng)手輪，閥桿會(huì)在向上升的同時(shí)帶動(dòng)球體趨向閥座。軌道硬密封球閥將要開(kāi)啟時(shí)，閥桿上的精密螺旋曲線槽軌道與嵌于其中的導(dǎo)向銷相互作用帶動(dòng)球體在與閥座密封面完全無(wú)摩擦的情況下不停地按逆時(shí)針?lè)较蜣D(zhuǎn)動(dòng)。繼續(xù)轉(zhuǎn)動(dòng)手輪，當(dāng)閥桿升到極限位置時(shí)，此時(shí)球也已隨閥桿倒轉(zhuǎn)了90°，閥門(mén)已處于全開(kāi)位置。軌道硬密封球閥結(jié)構(gòu)特點(diǎn)：傳統(tǒng)的球閥，無(wú)論是浮動(dòng)式或固定式，球體與閥座始終接觸，開(kāi)關(guān)扭矩大，密封面容易損傷，軌道球論著啟閉時(shí)，球體先偏轉(zhuǎn)-δ角，然后轉(zhuǎn)動(dòng)，開(kāi)關(guān)全過(guò)程中球體與閥座脫離，故閥座不會(huì)被擦傷，并且啟閉扭矩小。
