三分體式連接鍛鋼固定球閥，是將閥體在兩閥座部位沿與閥門通道軸線相垂直的截面分為三部分，整臺(tái)閥門沿閥桿中心軸左右對(duì)稱，它在管道上主要用于切斷、分配和改變介質(zhì)流動(dòng)方向。它的大樞軸結(jié)構(gòu)保證在高壓下準(zhǔn)確的球體中心位置，保證了閥門良好的操作性能；標(biāo)準(zhǔn)閥座采用彈簧結(jié)構(gòu)，將閥座推向球體，保證了良好的進(jìn)出口雙向密封性能；利用自帶的排放閥，閥體中腔可向外排放；樞軸采用防吹出保護(hù)結(jié)構(gòu)，有效地防止泄漏；低磨擦系數(shù)的軸承，使得扭矩減少到小，便于閥門啟閉；閥桿與閥體有效的接觸，使防靜電接地裝置性能*等。具有性能優(yōu)異，可靠性高，用途廣泛，價(jià)格合理等優(yōu)點(diǎn)。

The main parts of imported high-pressure ball valves are forged by professional manufacturers, which overcomes the potential defects of cast steel valves and maintains the uniformity of pressure resistance under the maximum working pressure. Applicable media: water, oil, gas and other non-corrosive media and acid-base corrosive media. Electric high-pressure ball valves are widely used in chemical industry, petroleum, natural gas, metallurgy, and other industries, as well as in natural gas pipelines with hydrogen sulfide medium, many impurities and serious corrosion. The main characteristics of the electric high pressure ball valve are as follows:

 

The three-body connection forged steel fixed ball valve divides the cross-section of the valve body at two seats perpendicular to the axis of the valve passage into three parts. The whole valve is symmetrical along the central axis of the valve stem. It is mainly used to cut off, distribute and change the direction of medium flow in the pipeline. Its large pivot structure ensures accurate ball center position under high pressure and good operation performance of the valve; the standard valve seat adopts spring structure to push the valve seat to the ball, which ensures good two-way sealing performance for inlet and outlet; the valve body cavity can be discharged outward by using the self-contained discharge valve; the pivot adopts blowout-proof protection. The structure can effectively prevent leakage; the bearing with low friction coefficient can minimize the torque and facilitate the opening and closing of the valve; the effective contact between the stem and the valve body can make the anti-static grounding device have superior performance. It has the advantages of excellent performance, high reliability, wide use and reasonable price.

【進(jìn)口高壓小型球閥】結(jié)構(gòu)特點(diǎn)：

①流體阻力小，球閥是所有閥類中流體阻力小的一種，即使是縮徑球閥，其流體阻力也相當(dāng)小。

②開關(guān)迅速、方便，只要閥桿轉(zhuǎn)動(dòng)90o，球閥就完成了全開或全關(guān)動(dòng)作，很容易實(shí)現(xiàn)快速啟閉。

③閥座密封性能好。大多數(shù)球閥的密封圈都采用聚四乙烯等彈性材料制造，軟密封結(jié)構(gòu)易于保證啟封，而且球閥的密封力隨著介質(zhì)壓力的增高而增大。

④閥桿密封可靠。球閥啟閉時(shí)閥桿只作旋轉(zhuǎn)運(yùn)動(dòng)而不作升降運(yùn)動(dòng)，閥桿的填料密封不易破壞，且閥桿倒密封的密封力隨著介質(zhì)壓力的增高而增大。

⑤由于聚四氟乙烯等材料具有良好的自潤(rùn)滑性，與球體的摩擦損小，故球閥的使用壽命長(zhǎng)。

⑥可配置氣動(dòng)、電動(dòng)、液動(dòng)等多種驅(qū)動(dòng)機(jī)構(gòu)，實(shí)現(xiàn)遠(yuǎn)距離控制和自動(dòng)化操作。

⑦閥體內(nèi)通道平整光滑，可以輸送粘性流體、漿液以及固體顆粒。

⑧安裝簡(jiǎn)便，能以任意方向安裝于管道中的任意部位。
