Koob li qub, nrog lawv cov koob tshwj xeeb conical - zoo li lub valve core tsim, yog tsim rau cov ntawv thov tseem ceeb hauv qab no:
1. High-kev tswj xyuas qhov tseeb: Lub feeb qhov sib txawv ntawm lub valve tub ntxhais thiab lub rooj zaum (feem ntau tsawg dua 0.1mm) tso cai rau milliliter- theem kev tswj hwm, feem ntau siv hauv chav kuaj chromatographs, cov khoom siv tshuaj ntsuam xyuas roj, thiab lwm yam uas yuav tsum tau ntsuas kom meej.
2. High- tswj cov kua dej siab: Nrog rau siab txog li 1000 Bar (xa mus rau *Industrial Valve Technology Handbook*), haum rau siab - ib puag ncig siab xws li petrochemical pipelines thiab hydraulic systems.
3. Corrosive media tuav: Valve lub cev cov ntaub ntawv suav nrog 316 stainless hlau thiab Hastelloy, muaj peev xwm tiv taus cov kua qaub thiab alkalis, xws li hauv kev siv tshuaj electroplating kev thauj mus los lossis kev lag luam tshuaj.
4. Vacuum system sealing: The tight fit between the valve core and seat maintains a vacuum level of 10⁻³Pa, used in semiconductor manufacturing or vacuum coating equipment.
