I-American Standard Rising Stem Flanged Gate Valve

Isimiso Esisebenzayo se-ASME Rising Stem Flanged Gate Valve

Lapho u-opharetha ephendula isondo lesandla, isondo lesandla lishayela isiqu se-valve ukuze sijikeleze. Intambo ye-trapezoidal ekugcineni kwesiqu se-valve ihlangana ne-valve stem nut, iguqule ukunyakaza okujikelezayo kube ukunyakaza kwe-axial linear. Njengoba isiqu se-valve nesango kuxhunyiwe, isiqu se-valve sizoshayela isango ukuze likhuphuke noma liwe ndawonye.

Ukuze uvule i-valve, jikisa isondo lesandla ngokuphambene newashi. Isiqu se-valve sishayela isango ukuthi liye phezulu ngokunyakaza okulandelanayo, okwenza isango liphume esihlalweni. Lapho isango liphakanyiselwe ukuphakama elilingana nobubanzi obuphindwe kabili be-valve, umzila owuketshezi awuvimbeki ngokuphelele, futhi i-valve isendaweni evulekile ngokugcwele. Ngesikhathi sokusebenza, isondo lesandla livamise ukujikelwa endaweni lapho lingakwazi ukuqhubekela phambili khona, bese libuyiselwa emuva uhhafu wokujika liye kwelinye ukuze lifinyelele indawo evuleke ngokugcwele, livimbele isiqu se-valve ekukhiyeni ngenxa yokushintsha kwezinga lokushisa.

Ukuvala i-valve, vula isondo lesandla ngokwewashi. Isiqu se-valve sishayela isango ukuthi liye phansi ngokunyakaza okulandelanayo, okwenza isango licindezele isihlalo sevalvu. I-torque esetshenziswa isondo lesandla ikhiqiza amandla okuvala ngempoqo, futhi ukucindezela kwendawo ephakathi epayipini iphinde icindezele isango kwesinye isihlalo se-valve, okwenza umphumela wokuzivala. Lesi senzo esikabili siqinisekisa ukuvuza okuyiziro uma kuvaliwe.

Isici esiyinhloko se-valve yesango le-stem elikhuphukayo ukuthi isiqu se-valve siyakhuphuka futhi siwe ngokuhambisana nesango. Ama-opharetha angakwazi ukubona ngeso lengqondo isimo sevalvu evulekile/evaliwe ngokubheka ubude besiqu se-valve esidlulela ngale kwesembozo se-valve—uma isiqu sinwebeka, ivalvu ivuleka kakhulu; lapho isiqu sihoxisiwe ngokugcwele, i-valve ivaliwe.

Kubaluleke kakhulu ukuqaphela ukuthi i-ASME (American Standard) amavalvu esango le-stem flange ekhuphukayo angasetshenziswa kuphela ezindaweni ezivuleke ngokugcwele noma ezivalwe ngokugcwele futhi angeke asetshenziswe njengamavalvu okulawula. Uma ishiywe endaweni evuleke kancane isikhathi eside, indawo egeleza ngesivinini esiphezulu izoguguleka indawo yokuvala, ibangele ukuguga kwesango nesihlalo, ekugcineni kuholele ekuvuzeni kwamavalvu. Ngaphezu kwalokho, i-medium ingageleza isuka nhlangothi zombili zevalvu yesango kunoma iyiphi indlela, isuse isidingo sokucabangela ukugeleza kokuqondisa ngesikhathi sokufakwa kanye nokwenza lula ukwakheka kwesayithi.

Amapharamitha womkhiqizo

Izinga Lokushisa Eziphezulu kanye Nokumelana Nokucindezela Okuphezulu

I-Shenchi ASME Standard Rising Stem Flanged Gate Valves iqhosha ngezinzuzo ezimbili zokusebenza eziyinhloko: ukumelana nokushisa okuphezulu nokumelana nokucindezela okuphezulu. Impahla ye-WCB ingamelana namazinga okushisa afika ku-425 ℃, kuyilapho insimbi engagqwali ifanele izinga lokushisa elibanzi. Isilinganiso sokucindezela se-Class 150, ingcindezi yokusebenza ifinyelela ku-1.9MPa ekamelweni lokushisa, idlula izinga le-PN16. Izivalo zitholakala nge-PPL ekwazi ukumelana nezinga lokushisa eliphezulu noma ngezinhlobo ze-EPDM ezingangeni emanzini. Yenziwe e-China, i-Shenchi isebenzisa ukulawulwa kwekhwalithi okuphelele kusuka ezintweni ezingavuthiwe kuya emikhiqizweni eqediwe, iqinisekisa ukusebenza okuzinzile kwesikhathi eside ngaphansi kwezinga lokushisa eliphezulu nezimo zengcindezi ephezulu.

Ukusebenza okuthembekile kokucindezela okuphezulu okudlula amazinga e-Class 150

I-Shenchi's ASME B16.10 standard rising stem flange valvu iqhosha ngokumelana okuthembekile kwengcindezi ephezulu. Uxhumano lwe-flange luhambisana namazinga e-ASME B16.10, anamabhawodi aqiniswe ngokulinganayo kanye nokusabalalisa kwengcindezi efanayo kuma-gaskets. Isilinganiso se-Class 150 sinikeza ingcindezi yokusebenza engu-1.9 MPa ekamelweni lokushisa, ngemajini eyanele yokucindezela elinganiselwe. Ukujiya kodonga lomzimba we-valve kuklanywe ngokuvumelana namazinga e-ASME, adlula izindinganiso zikazwelonke zokuphepha okuthuthukisiwe. I-Shenchi inikeza ama-valve esango esango le-ASME elinesaphulelo elikhuphukayo; ukuthenga ngobuningi kufaneleka ukuthola izaphulelo futhi kuqinisekise ukusebenza okuzinzile kwesikhathi eside ngaphansi kwezimo zengcindezi ephezulu.

I-Factory Direct Procurement kanye Nokwesekwa Kokwenza Ngokwezifiso kwe-OEM

I-Shenchi, njengomphakeli we-ASME (American Standard) amavalvu esango le-stem flange akhuphukayo, inikeza izinsizakalo zokwenza isampula. Sinikeza amavalvu esango le-ASME akhuphukayo akhuphukayo ngamanani efekthri asobala, sisusa ama-middlemen markups. Sisekela i-ODM ne-OEM ngokwezifiso; izinto zokwakha, ububanzi, amazinga e-flange, nezindlela zokusebenza konke kungalungiswa ngokwezidingo zakho. Amavalvu esango esango le-ASME akhuphukayo kulula ukuwagcina, anesakhiwo esilula kanye nezindleko zokunakekela eziphansi. Kwenziwe e-China, i-Shenchi ASME ama-valve esango le-stem flange akhuphukayo athembekile ngekhwalithi futhi anezikhathi zokulethwa ezizinzile. Amakhasimende omhlaba amukelekile ukuthi athinte i-Shenchi ukuze uthole imininingwane enemininingwane yemibandela yobuchwepheshe kanye nezingcaphuno zakamuva ezithandwayo.
