二、進(jìn)口高壓小型球閥結(jié)構(gòu)優(yōu)點(diǎn)：

1、止推軸承減小閥桿摩擦力矩，可使閥桿長(zhǎng)期操作平衡靈活。

2、高壓球閥閥座密封性能好，采用聚四氟乙烯等彈性材料制成的密封圈，結(jié)構(gòu)易于密封，而且球閥的密封能力隨著介質(zhì)壓力的增高而增大。

3、閥桿密封可靠，由于閥桿只作旋轉(zhuǎn)運(yùn)動(dòng)而不做升降運(yùn)動(dòng)，閥桿的填料密封不易破壞，且密封能力隨著介質(zhì)壓力增高而增大。

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

1. The thrust bearing reduces the friction torque of the valve rod, which makes the long-term operation balance of the valve rod flexible.

2. The sealing performance of the valve seat of high pressure ball valve is good. The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal, and the sealing capacity of the ball valve increases with the increase of medium pressure.

3. The valve rod seal is reliable, because the valve rod only rotates without lifting, the packing seal of the valve rod is not easy to be damaged, and the sealing capacity increases with the increase of medium pressure.

4. High pressure ball valve has a long service life because of its good self-lubricating property and small friction loss with the ball.

三、進(jìn)口高壓小型球閥描述：

德國(guó)《LOCKE》洛克進(jìn)口高壓小型球閥(High pressure ball valve)該球閥在開(kāi)啟時(shí)利用二塊式球體的優(yōu)點(diǎn),先水平收攏瞬間脫離閥座,然后再旋轉(zhuǎn)90度全開(kāi)。高壓球閥適用于Class 150～2500LB,工作溫度-28～600℃的石油,化工,火力電站等各種工況的管路上,其安全,耐惡劣環(huán)境性等的設(shè)計(jì)均已進(jìn)行特殊考慮,適用介質(zhì)為：水,蒸汽,油品,酸類,醋酸,尿素等腐蝕性和強(qiáng)氧化性介質(zhì)。操作方式有：手動(dòng),氣動(dòng),電動(dòng),液動(dòng)和氣液聯(lián)動(dòng)等。

The high pressure ball valve imported by Locke in Germany uses the advantages of two piece ball when it is opened. It first closes horizontally and breaks away from the valve seat, and then rotates 90 degrees to fully open. The high-pressure ball valve is applicable to the pipelines of class 150-2500lb, operating temperature - 28-600 ℃ in petroleum, chemical industry, thermal power station and other working conditions. The design of its safety and resistance to harsh environment has been specially considered. The applicable media are: water, steam, oil, acids, acetic acid, urea and other corrosive and strong oxidizing media. Operation mode: manual, pneumatic, electric, hydraulic and gas-liquid linkage.
