全焊接球閥
Full welded ball valve
閥門由全焊接的閥體和碳增強(qiáng)氟隆密封墊組成，可以在頻繁操作，有雜質(zhì)及化學(xué)物質(zhì)的情況下長壽命運(yùn)行。研磨精細(xì)的不銹鋼球體可以保證多年開閉自如，運(yùn)行可靠。
采用浮球結(jié)構(gòu)，斜面彈性保證密封圈緊壓在球體之上，即使在壓力不穩(wěn)定的情況下，閥門可以保證嚴(yán)密。
閥桿的防泄漏結(jié)構(gòu)使用兩“Q"型圈，使閥桿轉(zhuǎn)動(dòng)自如且密封嚴(yán)密。
特性：
不需要維護(hù)，調(diào)整及潤滑，易于安裝，在低運(yùn)行費(fèi)用下*可靠運(yùn)行。
閥桿可以加長、易于保溫。
操作手柄可以拆下，換向安裝。
閥體不含沉重且不可靠的鑄件。
安裝調(diào)節(jié)機(jī)構(gòu)，非常簡便。

Gate valve is composed of body of full-welded and packing seal of carbon fiber Teflon. It can prolong its life with impurities and chemical substances when it’s operated frequently. Fine grinding of stainless steel ball can guarantee opening and close for several years and reliability service.
Using float structure, flexibility of slope can ensure sealing ring pressing in the ball, even if in instability pressure, valve also can guarantee sealing efficiency.
Anti-leakage of stem with O-ring makes stem turning convenient.
Character:
Needn’t maintenance, adjustable and lubrication, it also can be operated for a long time in low fee.
Stem can be lengthened and it’s easy to heat.
Operating handle can be removed to change the installed.
Body does not contain heavy and unreliable castings.
It’s easy to install adjustment.
