德國奧萊斯OLES進(jìn)口電站止回閥
【進(jìn)口電站止回閥】詳細(xì)說明:
其遵循的溫度、壓力等級是*的,在一些管道中存在著某種互換關(guān)系。中部采用無閥蓋壓力自緊式,在高溫高壓工況下具有良好的密封性能。自密封圈有兩種材料:一種是低碳鋼,另一種是柔性石墨夾316絲(網(wǎng))。密封面堆焊鉆基硬質(zhì)合金。其加工后的純金屬層≥3mm,具有耐磨、耐高溫、抗腐蝕、抗擦傷、使用壽命長。適用于Class1500~2500Lb、工作溫度-29~570℃的石油、化工、火力電站等各種工況的管路上。適用介質(zhì)為:水、油品、蒸汽等。閥門中腔采用壓力自緊式密封結(jié)構(gòu),內(nèi)腔壓力越高密封性能越好。支管兩端為對焊連接,適應(yīng)不同的接管要求。
It follows the same temperature and pressure levels, and there is some exchange relationship in some pipelines. The middle part adopts pressure self-tightening type without valve cover, which has good sealing performance under high temperature and high pressure. There are two kinds of materials for self-sealing ring: one is low carbon steel, the other is flexible graphite clip 316 wire (mesh). Surfacing of sealing surface with drill-based cemented carbide. The processed pure metal layer (> 3mm) has wear resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life. It is suitable for pipelines of Class1500-2500Lb and working temperature-29-570 C in petroleum, chemical and thermal power stations. Applicable medium: water, oil, steam, etc. The inner chamber of the valve adopts pressure self-tightening sealing structure, the higher the pressure of the inner chamber, the better the sealing performance. The two ends of branch pipe are butt welded to meet different nozzle requirements.
【進(jìn)口電站止回閥】特點(diǎn):
產(chǎn)品設(shè)計(jì)結(jié)構(gòu)合理,密封可靠,性能優(yōu)良,造形美觀。閥瓣、閥座的密封面采用司太立(stellite)鈷基硬質(zhì)合金堆焊而成,耐磨、耐高溫,抗擦傷性能好、使用壽命長。可采用各種配管法蘭標(biāo)準(zhǔn)及法蘭密封面型式,滿足各種工程需要及用戶要求。 閥體材料品種齊全,填料、墊片根據(jù)實(shí)際工況或用戶要求合理選配,能適用于各種壓力、溫度及介質(zhì)工況。.閥瓣圍繞閥座外的銷軸旋轉(zhuǎn),減少關(guān)閉時(shí)發(fā)生猛烈沖擊。
銷軸與閥瓣連接采用內(nèi)裝式的銷軸結(jié)構(gòu),減小外泄漏點(diǎn),使用更可靠。
