I-GB Hard and Soft Ukutywina iiValuvu zeBhola ezidadayo isishwankathelo: Ukusebenza, usetyenziso, kunye neMigangatho
Umgangatho wesizwe ivelufa yebhola ethambileyo netywiniweyo eqinileyo sisivalo esisetyenziselwa ukulawula amajelo olwelo, anokusebenza kakuhle kokutywinwa kunye nokuxhathisa ulwelo oluncinci. Kweli nqaku, siza kwazisa iimpawu, izicelo, kunye neenkcukacha eziphambili zokusebenza zomgangatho wesizwe othambileyo notywiniweyo wevalvu yebhola edadayo.
1. Iimpawu zemveliso
Umgangatho wesizwe ivelufa yebhola ethambileyo netywiniweyo eqinileyo inezi mpawu zilandelayo:
-Ukuxhathisa ulwelo oluphantsi: Iivalvu zebhola zinezona zithintelo zolwelo ezisezantsi phakathi kwazo zonke iintlobo zevalvu, nokuba kuncitshisiwe iivalvu zebhola, ukuxhathisa kwazo ulwelo kuncinci.
-Ukuvula nokuvala ngokukhawuleza kunye nokufanelekileyo: Ngethuba nje i-valve stem ijikeleza i-90 °, i-valve yebhola iya kugqiba ukuvulwa ngokupheleleyo okanye isenzo sokuvala ngokupheleleyo, okwenza kube lula ukufezekisa ukuvulwa nokuvala ngokukhawuleza.
-Ukusebenza kakuhle kokutywinwa: Isihlalo sevalve yebhola sivaliwe, kunye nokusebenza kakuhle kokutywinwa.
2. Ukusetyenziswa kweMveliso
Umgangatho wesizwe wevalve yebhola edadayo ethambileyo netywiniweyo ifanelekile kwipetroleum, igesi yendalo, imichiza, amayeza, ukutya, umbane, unikezelo lwamanzi, isinyithi, kunye namashishini okwakha. Ivalve yebhola edadayo yeflange yindlela yoqhagamshelo eqhelekileyo, ilungele iimeko ezahlukeneyo zokusebenza.
3. Iinkcukacha zokusebenza eziphambili
Uxinzelelo lwegama (MPa): Uluhlu loxinzelelo lwegama lomgangatho wesizwe ivelufa yebhola edadayo ethambileyo etywiniweyo eqinileyo yi-0.6 ~ 42.0 MPa, kwaye amanqanaba oxinzelelo afanelekileyo anokukhethwa ngokweemeko ezahlukeneyo zokusebenza.
Iqondo lobushushu elisebenzayo: Uluhlu lobushushu obusebenzayo kumgangatho wesizwe oqhelekileyo othambileyo notywiniweyo wevalvu yebhola edadayo yi-196 ℃ ~ 550 ℃, ngelixa iivalvu zebhola ezithambileyo ezitywiniweyo nezitywiniweyo zifanelekile kwirhasi yendalo, i-petroleum kunye nezinye izinto eziqulethe i-H2S. kunye ne-CO2.
Imidiya esebenzayo: Izivalo zebhola ezidadayo ezithambileyo nezitywiniweyo ezisemgangathweni zifanelekile kumajelo osasazo afana namanzi, umphunga, i-petroleum, irhasi enyibilikisiweyo, kunye nerhasi yendalo.
4. Izinto zecandelo eliphambili
Izinto eziphambili zecandelo lomgangatho wesizwe othambileyo notywiniweyo wevalve yebhola edadayo ibandakanya uthotho lwentsimbi yekhabhoni, uthotho lwensimbi engenasici, uthotho oluxhathisa isalfure, kunye nobushushu obuphantsi bentsimbi. Ezi zixhobo zinokuhlangabezana neemfuno zeemeko ezahlukeneyo zokusebenza, ukuqinisekisa ukuqina kunye nokuthembeka kwevalve.
5. Imigangatho yokwenziwa
Umgangatho wesizwe othambileyo notywiniweyo wevalve yebhola edadayo iyilwe kwaye yenziwe ngokuhambelana nemigangatho efana ne-GB/T12237, GB/T12221, GB/T12224, kunye ne-GB/T12220. Le migangatho ichaza iimfuno zobude besakhiwo, ukudibanisa i-flanges, ukuhlolwa kunye nokuhlolwa kwee-valve, ukuqinisekisa umgangatho othembekileyo wemveliso.
Ngamafutshane, umgangatho wesizwe othambileyo noqinileyo ivelufa yebhola edadayo etywiniweyo sisivalo esisebenza ngokugqwesileyo, esisetyenziswa ngokubanzi kumasimi ahlukeneyo oshishino. Ukuqonda iimpawu zayo, ukusetyenziswa, kunye neenkcukacha eziphambili zokusebenza kunokusinceda ukuba sikhethe ngcono kwaye sisebenzise olu hlobo lwesivalo.
