產(chǎn)品結(jié)構(gòu)特點 Construction features

1、產(chǎn)品按國家標(biāo)準(zhǔn)GB/T 12236設(shè)計制造，結(jié)構(gòu)合理，密封可靠，性能優(yōu)良。
2、閥瓣和閥座的密封面用鐵基合金或司太立（stellite）鈷基硬質(zhì)合金堆焊而成，耐磨、耐高溫、耐腐蝕，抗擦傷性能好，使用壽命長。
3、可采用各種配管法蘭標(biāo)準(zhǔn)及法密封面型式，滿足各種工程需要及用戶要求。
4、閥體材料品種齊全，墊片可根據(jù)實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。
5、閥瓣圍繞閥座外的銷軸旋轉(zhuǎn)，減少關(guān)閉時發(fā)生猛烈沖擊。
6、銷軸與閥瓣連接采用內(nèi)裝式結(jié)構(gòu)，不存在外泄漏點，使用更可靠。
1. The products are manufactured according to national standard GB/T 12236, with reasonable structure, reliable sealing and excellent performance.
2. The sealing surface of disc and seat is made of iron base alloy or stellite (stellite) cobalt base hard alloy. It is wear-resistant, high temperature resistant, corrosion resistant, good abrasion resistance and long service life.
3. All kinds of piping flange standard and sealing cover type can be used to meet various engineering needs and user requirements.
4. The valve body material is complete, the gasket can be selected according to the actual working conditions or users, and can be applied to various pressure, temperature and medium conditions.
5. The disc revolves around the pin shaft outside the seat and reduces the impact when it is closed.
6. The pin shaft and disc connection are built in an internal structure, and there is no leakage leakage point, and the use is more reliable.
