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

1.雙重的密封設(shè)計(jì)（波紋管+填料）若波紋管失效，閥桿填料也會(huì)避免。
2.結(jié)構(gòu)合理、密封可靠、性能優(yōu)良、造型美觀。
3.沒(méi)有流體損失，降低能源損失，提高工廠(chǎng)設(shè)備安全。
4.密封面堆焊Co基硬質(zhì)合金、耐磨、耐腐、抗摩擦性能好、使用壽命長(zhǎng)，減少維修次數(shù)，降低經(jīng)營(yíng)成本。
5.堅(jiān)固耐用的波紋管密封設(shè)計(jì)，保證閥桿的零泄漏，提供無(wú)需維護(hù)的條件。
6.截止閥閥桿調(diào)質(zhì)及表面氮化處理，有良好的抗腐和抗摩擦性能；
7.閥桿升降位置指示更直觀。
1. Double seal design (bellows + filler) if bellows fail, stem packing will be avoided.
2. Reasonable structure, reliable sealing, excellent performance and beautiful appearance.
3. There is no fluid loss, reduce energy loss, and improve the safety of plant equipment.
4. The cover surfacing the Co base carbide, wear-resisting, anti-corrosion, anti-friction performance, the service life long, reduce the maintenance times, reduce the operating cost.
5. Strong and durable bellows seal design to ensure zero leakage of stem and provide conditions without maintenance.
6. The cut-off valve stem and surface nitride treatment have good anti-corrosion and anti-friction properties;
7. Valve stem elevation position indication is more intuitive.
