?進口高壓法蘭球閥描述--

RETZ高壓法蘭球閥材料是鍛造出來的，材質(zhì)的密度比鑄造的密度要大很多，特別適合高壓球閥的制造加工高壓鍛鋼球閥關(guān)閉件球體繞閥體中心線作旋轉(zhuǎn)來達到開啟、關(guān)閉的一種球閥，密封件嵌于不銹鋼閥座內(nèi)，金屬閥座尾端設(shè)有彈簧，當(dāng)密封面磨損或者燒毀時，在彈簧作用下推動閥座與球體形成金屬密封。其具有*的自動泄壓功能，當(dāng)閥門中腔介質(zhì)壓力超過彈簧預(yù)緊力，出口端閥座后退脫離球體，達到自動泄壓效果，泄壓后閥座自動復(fù)位.

RETZ high pressure flange ball valve material is forged. The density of material is much larger than that of casting. It is especially suitable for the manufacture and processing of high pressure ball valve. A ball valve that turns around the center line of the valve body of the high pressure forging ball valve is made to open and close. The seal is embedded in the stainless steel seat and the end of the metal seat is set at the end of the valve seat. When the sealing surface is worn or burned, the spring pushes the valve seat and the ball to form metal seal under the action of the spring. It has a unique automatic pressure relief function, when the medium pressure of the valve in the valve is more than the spring pretightening force, the outlet valve seat back out of the ball, to achieve the automatic pressure relief effect, the valve seat automatically reset after pressure relief.

?進口高壓法蘭球閥產(chǎn)品特點--

1.本產(chǎn)品所有部件均為鍛件

2.采用下裝式閥桿,設(shè)備倒密封結(jié)構(gòu)

3.采用鑲嵌式閥座,閥座背后設(shè)備O型圈,確保介質(zhì)不外漏

4.密封面采用尼龍,自然滑性材料,但抗彎曲強度和沖擊強度及較高的延性，與金屬不相上下

5.標(biāo)準(zhǔn)閥座采用彈簧結(jié)構(gòu)，將閥座推向球體，保證了良好的進出口雙向密封性能；

6.樞軸采用防吹出保護，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；

7.閥桿與閥體有效的接觸，使防靜電接地裝置性能*等。
