Iimpawu zokusebenza kwevalve yokhuseleko lomphunga

Ivalve yokhuseleko lwe-steam generator yenye yezinto eziphambili zokhuseleko zejenereyitha yomphunga.Inokuthintela ngokuzenzekelayo uxinzelelo lomphunga kwibhoyila ekugqithiseni uluhlu oluvumelekileyo olumiselweyo, ngaloo ndlela iqinisekisa ukusebenza ngokukhuselekileyo kwebhoyila.Sisixhobo sokhuseleko soxinzelelo olugqithisileyo.

Isetyenziswa ngokubanzi nangakumbi ebomini bethu, kwaye idlala indima ekuqinisekiseni ukhuseleko lokusebenza kweejenereyitha zomphunga.Ngokuqhelekileyo, ukufakela, ukulungiswa, kunye nokugcinwa kufuneka kwenziwe ngokuhambelana nemimiselo.

Iimpawu zokusebenza kwevalve yokhuseleko lomphunga:

1. Ivalve yokhuseleko lomphunga kufuneka ifakwe ngokuthe nkqo kwindawo ephezulu yophawu lwentengiso ye-steam generator kunye nentloko.Akukho mibhobho yokukhupha umphunga okanye iivalvu ziya kufakelwa phakathi kwevalve yokhuseleko kunye negubu okanye iheader.

2. I-valve yokhuseleko lwe-steam yohlobo lwe-lever kufuneka ibe nesixhobo sokuthintela ubunzima ukuba bungahambi ngokwaso kunye nesikhokelo sokunciphisa ukuphambuka kwe-lever.Ivalve yokhuseleko lohlobo lwasentwasahlobo kufuneka ibe nesibambo sokuphakamisa kunye nesixhobo sokuthintela isikrufu sokulungelelanisa ukuba singajikwa ngokungaqhelekanga.

3. Kwiibhoyila ezinoxinzelelo olulinganisiweyo lomphunga ongaphantsi okanye olingana ne-3.82MPa, ububanzi bomqala wevalve yokhuseleko lomphunga akufanele ibe ngaphantsi kwe-25nm;kwiibhoyila ezinoxinzelelo lomphunga olulinganiswe ngaphezu kwe-3.82MPa, ububanzi bomqala wevalve yokhuseleko kufuneka bungabi ngaphantsi kwe-20mm.

4. Indawo enqamlezileyo yombhobho wokudibanisa phakathi kwevalve yokhuseleko lomphunga kunye nebhoyila ayifanele ibe ngaphantsi kwe-inlet cross-sectional area yevalve yokhuseleko.Ukuba iivalve ezininzi zokhuseleko zifakwe kunye kumbhobho omfutshane oqhagamshelwe ngokuthe ngqo kwigubu, indawo enqamlezileyo yombhobho omfutshane ayifanele ibe ngaphantsi kwe-1.25 amaxesha okukhutshwa kwazo zonke iivalvu zokhuseleko.

5. Iivalve zokhuseleko lomphunga kufuneka ngokuqhelekileyo zixhotyiswe ngemibhobho yokukhupha, ekufuneka iholele ngokuthe ngqo kwindawo ekhuselekileyo kwaye ibe nendawo eyaneleyo ye-cross-sectional ukuqinisekisa ukuhamba kakuhle kwe-exhaust steam.I-bottom ye-exhaust pipe ye-valve yokhuseleko kufuneka yenziwe ngathi i-drain pipe exhunywe kwindawo ekhuselekileyo.Iivalvu azivumelekanga ukuba zifakwe kumbhobho wokukhupha okanye umbhobho wokukhupha amanzi.

6. Iibhoyila ezinomthamo olinganisiweyo wokuphuphuma komphunga omkhulu kune-0.5t/h kufuneka zixhotyiswe ubuncinane ngeevalvu zokhuseleko ezimbini;iibhoyila ezinomthamo olinganisiweyo wokuphuphuma komphunga ngaphantsi okanye olingana ne-0.5t/h kufuneka zixhotyiswe ubuncinane ivelufa yokhuseleko enye.Iivalvu zokhuseleko kufuneka zifakwe kwindawo yokuphuma ye-economizer ekwahlulwayo kunye nendawo yokuphuma yesifudumezisi esikhulu somphunga.

7. I-valve yokukhusela i-steam yesitya soxinzelelo ifakwe ngokufanelekileyo ngokuthe ngqo kwindawo ephezulu ye-pressure body body.Ivalve yokhuseleko yetanki yokugcina igesi enyibilikisiweyo kufuneka ifakwe kwisigaba segesi.Ngokuqhelekileyo, umbhobho omfutshane ungasetyenziselwa ukudibanisa kwisitya, kwaye ububanzi bombhobho omfutshane wevalve yokhuseleko akufanele bube buncinci kunobubanzi bevalve yokhuseleko.

8. Iivalvu ngokuqhelekileyo azivumelekanga ukuba zifakwe phakathi kweevalve zokhuseleko lomphunga kunye nezikhongozeli.Kwizikhongozeli ezinokutsha, ukuqhuma okanye i-viscous media, ukwenzela ukuba kube lula ukucocwa okanye ukutshintshwa kwevalve yokhuseleko, i-valve yokumisa ingafakwa.Le valve yokumisa kufuneka ifakwe ngexesha lokusebenza okuqhelekileyo.Ivulwe ngokupheleleyo kwaye itywinwe ukunqanda ukuphazamisa.

9. Kwiinqanawa zoxinzelelo ezinomlilo ovuthayo, ukuqhuma okanye i-toxic media, i-media ekhutshwe yi-valve yokukhusela i-steam kufuneka ibe nezixhobo zokukhusela kunye neenkqubo zokubuyisela.Ukufakwa kwe-valve yokukhusela i-lever kufuneka kugcinwe indawo ethe nkqo, kwaye i-valve yokukhusela i-spring nayo ifakwe ngokufanelekileyo ngokuthe ngqo ukuphepha ukuchaphazela isenzo sayo.Ngethuba lokufakela, ingqalelo kufuneka ihlawulwe ngokufanelekileyo, i-coaxiality yamacandelo, kunye noxinzelelo olufanayo kwi-bolt nganye.

10. Iivalvu ezitsha zokhuseleko lomphunga kufuneka zikhatshwe sisiqinisekiso semveliso.Ngaphambi kofakelo, kufuneka zihlaziywe, zitywinwe kwaye zikhutshwe ngesatifikethi sokulinganisa ivalve yokhuseleko.

11. Ukuphuma kwevalve yokhuseleko lomphunga kufuneka kungabi nakuphikiswa ukuphepha ukunyanzeliswa ngasemva.Ukuba ipayipi yokukhupha ifakwe, ububanzi bayo bangaphakathi kufuneka bube bukhulu kunobubanzi bokukhutshwa kwevalve yokhuseleko.Indawo yokukhutshwa kwevalve yokhuseleko kufuneka ikhuselwe ekukhenkceni.Ayifanelanga isikhongozeli esinokutsha okanye esinetyhefu okanye esinetyhefu kakhulu.Kwimibhobho yemidiya, umbhobho wokukhupha kufuneka udibaniswe ngokuthe ngqo kwindawo engaphandle ekhuselekileyo okanye ube nezixhobo zokulahla ngokufanelekileyo.Akukho zivalo zivumelekileyo kumbhobho wokukhupha.

12. Akukho valve iya kufakwa phakathi kwesixhobo soxinzelelo kunye nevalve yokhuseleko lomphunga.Kwizikhongozeli eziphethe imidiya evuthayo, eqhumayo, enetyhefu okanye ebonakalayo, ukwenzela ukuba kube lula ukutshintshwa kunye nokucoca, ivalve yokumisa inokufakwa, kwaye isakhiwo sayo kunye nobukhulu bedayamitha abuyi kwahluka.Kufuneka kuthintele ukusebenza okuqhelekileyo kwevalve yokhuseleko.Ngethuba lokusebenza okuqhelekileyo, i-valve yokumisa kufuneka ivule ngokupheleleyo kwaye ivalwe.
