Umgaqo-siseko woyilo kunye nohlalutyo lwendlela yokusebenza yeevalvu zokukhupha ezinyukayo nezisezantsi
Kwiinkqubo zolawulo oluzenzekelayo kwimizi-mveliso, iivalvu zokukhupha ezandisiweyo eziphezulu nasezantsi zidlala indima ebalulekileyo. Uyilo lwezivalvu luvumela izinto ukuba zingene ngokuchanekileyo okanye ziphume kwisitya phantsi kweemeko ezithile. Eli nqaku liza kunika uhlalutyo olucacileyo lwemigaqo yokuyila kunye neendlela zokusebenza kwezo zivalo zokukhupha.
umgaqo woyilo
Umahluko omkhulu phakathi kweevalve zokukhupha phezulu nangaphantsi yindlela yazo yokuvula. Xa ivalve yokukhupha eyongeziweyo ivuliwe, i-valve core ihambela phezulu ukuze ivule umjelo wokuhamba; Ivalve yokukhupha isandisi esisezantsi sifezekisa umphumo ofanayo ngokuhambisa i-valve core ezantsi. Olu luyilo lubavumela ukuba bafakwe ngaphandle kokuphazamiseka phantsi okanye phezulu kumbhobho.
- Uyilo lwesakhiwo: Ezi ntlobo zimbini zeevalvu zihlala zibandakanya umzimba wevalvu, isigqubuthelo sevalvu, isitulo sevalvu, kunye nombindi wevalvu. Phakathi kwazo, isihlalo sevalve kunye nesiseko sevalve zizinto eziphambili zokuqinisekisa ukusebenza kokutywinwa.
- Indlela yokutywina: Ukuqinisekisa isiphumo sokutywinwa, iivalvu ezikhuphayo ezingaphezulu nezisezantsi zisebenzisa imiphezulu echanekileyo ehambelana nomatshini phakathi kwesihlalo sevalve kunye nombindi wevalvu, kwaye ngokuqhelekileyo zisebenzisa imithombo yoxinzelelo kunye nezinye iindlela zokubonelela ngoxinzelelo olongezelelweyo ukunyusa ukutywinwa.
- Ukukhethwa kwezinto eziphathekayo: Ngokwezinto ezahlukeneyo zokucubungula, izinto ezahlukeneyo zingakhethwa kumzimba we-valve kunye nengundoqo, njengensimbi engenasici, i-carbon steel okanye i-alloys ekhethekileyo, kunye ne-rubber okanye i-PTFE (i-polytetrafluoroethylene) njengezinto zokutywina.
Indlela yokusebenza
- Ivalve yokukhupha eyongeziweyo:
-Xa imathiriyeli kufuneka ikhutshwe, sebenzisa amandla kwi-valve stem ngokusebenzisa i-hydraulic, i-pneumatic okanye i-actuator yombane ukuhambisa isiqu sevalve kunye ne-valve core egxininiswe kuyo phezulu.
-Phakamisa undoqo wevalve kwisihlalo sevalve, vula umjelo wokuhamba, kwaye uvumele izinto ukuba ziphume kwisitya.
-Xa ukukhutshwa kugqityiwe, i-actuator iyancipha kwaye i-valve core iphinda ihlaziywe ngenxa yobunzima bayo okanye i-spring yokuvala encedisayo, ukuvala umjelo wokuhamba.
- Ivalve yokukhupha eyongeziweyo ezantsi:
-Indlela yokusebenza yevalve yokukhupha isandisi esisezantsi iyafana naleyo yevalve eya phezulu, ngaphandle kokuba undoqo wevalve uhambela ezantsi ukuze uvule umjelo wokuhamba.
-I-actuator ityhala isiqu sevalve kunye nombindi ukuya ezantsi ukuvula umjelo kunye nokukhulula izinto.
-Xa ivaliwe, i-valve core iyaphakanyiswa kwaye iphinde ibuyiselwe ukubuyisela imeko yokutywinwa.
Ukuyila kwezi zivalo zimbini zokukhupha zivumela ukukhawuleza kunye nokulawulwa kokuhamba okuchanekileyo, okwenza ukuba zifaneleke ngokukodwa kwiimeko ezifuna ukuvulwa nokuvala rhoqo. Ingaba kukwandiswa okunyukayo okanye okuphantsi, ukuyila kwabo kukuqinisekisa ukuba izinto eziphathekayo zinokukhutshwa ngokukhawuleza kwaye zikhutshwe ngokupheleleyo xa kuyimfuneko, ngelixa zigcina ukusebenza kokutywinwa okuphezulu kakhulu kwimeko evaliweyo.
Isishwankathelo, i-valve yokukhupha i-up and down expansion, kunye noyilo lwazo olulodwa kunye nomgaqo-siseko wokusebenza, ukubonelela ngezisombululo ezisebenzayo nezithembekileyo zokulawula iinkqubo ezahlukeneyo zoshishino. Xa abasebenzisi bekhetha ukuyisebenzisa, kufuneka bathathele ingqalelo iimfuno ezithile zesicelo, kubandakanywa izinto ezifana nesantya sokuhamba, ukuhamba rhoqo, iimpawu zemathiriyeli, kunye neemeko zofakelo, ukuqinisekisa ukuba isiphumo esihle sokusebenza siyafezekiswa. Ngokuqhubela phambili okuqhubekayo kobuchwepheshe, uyilo kunye nomsebenzi wezi zivalo zokukhupha nazo zihlala ziphuculwa ukuhlangabezana neemfuno ezingqongqo zesicelo semizi-mveliso.
