產(chǎn)品描述-
美國(guó)泰樂TYLER進(jìn)口高溫高壓焊接截止閥閥瓣、閥座的密封面采用司太立鈷基硬質(zhì)合金堆焊而成，耐磨、耐高溫，抗擦傷,啟閉時(shí)閥瓣行程小，啟閉時(shí)間短,中腔采用壓力自緊式密封結(jié)構(gòu)，密封性能越好。
性能特點(diǎn)-
閥桿經(jīng)調(diào)質(zhì)和表面氮化處理，有良好的搞腐蝕性和抗擦傷性;
閥瓣、閥座的密封面采用司太立鈷基硬質(zhì)合金堆焊而成，耐磨、耐高溫，抗擦傷性能好;
滑油不易流失、摩擦力小、閥門啟閉輕松、動(dòng)作靈敏;
啟閉時(shí)閥瓣行程小，時(shí)間短,工藝性能好;
具有上密封結(jié)構(gòu)，保證閥門開啟運(yùn)行時(shí)不經(jīng)閥桿外漏;
應(yīng)用范圍-
高溫高壓焊接截止閥適用于ANSI Class150～2500LB，工作溫度-20～570℃的石油、化工、火力電站等各種工況的管路上，切斷或接通介質(zhì),適用介質(zhì)為：水、油品、蒸汽等。

American Taylor TYLER imported high temperature and high pressure welding globe valves
Product description -
American wessing TYLER imported high temperature and high pressure welding cut-off valve disc and seat sealing surface using department too vertical cobalt-based hard alloy surfacing and become, wear-resisting, high temperature resistance, resistance to abrasion, open/close the valve stroke is small, opening and closing time is short, lumen self-tightening seal structure is adopted, and the sealing performance is better.
Performance characteristics -
The valve stem has good corrosion and abrasion resistance after adjustment and surface nitrification.
The sealing surface of disc and seat is made of stack-cobalt hard alloy. It is durable and high temperature resistant and good abrasion resistance.
The lubricating oil is not easy to lose, the friction is small, the valve is open and easy, the movement is sensitive.
The valve disc has a short stroke, short time and good process performance.
The upper sealing structure ensures that the valve opens and runs without the stem leakage;
Application scope -
Welding of high temperature and high pressure cut-off valve is suitable for the ANSI Class150 ~ 2500 lb, working temperature - 20 ~ 570 ℃ in the petroleum, chemical, thermal power plant under various working conditions such as the pipeline, cut off or connect medium, applicable medium: water, oil, steam, etc.
Technical parameters -
Size: 3/8 ~ 4.
Nominal pressure: PN16-PN320BAR;
Working temperature: - 20 ℃ to 570 ℃;
Stem material: chromium nickel steel;
Body material: A105, F304, F316, F316L, F321, WC6, WC9;
Transmission mode: manual;
