產(chǎn)品結(jié)構(gòu)特點(diǎn) Construction features
1、產(chǎn)品設(shè)計(jì)制造按E101和JB/T 3595標(biāo)準(zhǔn)的規(guī)定,結(jié)構(gòu)合理,性能優(yōu)良,造型美觀。
2、閥門中腔采用壓力自緊式密封結(jié)構(gòu),介質(zhì)壓力越高,密封性能越好。
3、支管兩端為焊接結(jié)構(gòu),適應(yīng)不同的接管要求。
4、閥瓣、閥座密封面采用司太立(stellite)鈷基硬質(zhì)合金堆焊而成,耐磨、耐高溫、耐腐蝕、抗擦傷性能好、使用壽命長。
5、高溫耐壓部件采用優(yōu)質(zhì)耐熱合金鋼制造,安全可靠,性能穩(wěn)定,使用壽命長。
1. Product design and manufacturing shall be based on E101 and JB/T 3595 standard, with reasonable structure, excellent performance and beautiful appearance.
2. Pressure self-tightening seal structure is adopted in the valve middle cavity.The higher the medium pressure, the better the sealing performance.
3. The two ends of the branch are welded to meet different takeover requirements.
4. Disc, seat cover, and stellite (stellite) cobalt base alloy, which is used for hard wear, high temperature resistance, corrosion resistance, good abrasion resistance and long service life.
5. High temperature withstand pressure parts are made of high quality heat-resistant alloy steel, safe and reliable, stable performance and long service life.
