Gasket in the type of the force - 2013-08-22 20:51:36
Gasketstress situationcan bedivided intomandatoryseal,from the tight sealand semi-self-tight sealingthree categories, Forcedsealcompletely rely onexternal forces(such as bolts)the M-chipload is appliedto achieve; From the tight sealmainly usemedium pressureon the gasketapplied load; Whohave boththe above two methods, it is calledsemi-tight seal. Press theoperating pressure, the sealcan be divided intothe low-pressureseals, high pressureseals andhigh pressureseals: o. 098wherep ≤ l. 568MPawhenlow pressureseal; 9.8 ≤ P <98MPahigh-pressure sealwhen; WhenP ≥ 98MPahigh pressureseal. The typicalgeneral structure ofgasket sealand gasketformedby the connectingelement,the connectionof differentcomponentsof differentsealinginitialpressing forceis appliedby bolts,with medium pressureincrease,the pressurepadis also increased. Since thetight seal structuregenerally used forhypertension.Formedium and low voltagestructure,self-tighteningeffectis not obvious, the leakagerate is higher,it is not appropriateto use.
