"Indlela yokukhetha iValve yeGlobe ngokuchanekileyo: Isikhokelo kwiintlobo kunye neemeko zesicelo"
1,Isishwankathelo
Ivalve yeglowubhu luhlobo oluqhele ukusetyenziswa lwevalve, ikakhulu esetyenziselwa ukusika ulwelo kwimibhobho. Ukukhethwa okuchanekileyo kweevalve zokuvala kuyisitshixo sokuqinisekisa ukusebenza okuqhelekileyo kweenkqubo zemibhobho. Esi sikhokelo siya kukwazisa malunga nendlela yokukhetha ngokuchanekileyo i-valve yokuvala, kuquka uhlobo lwayo kunye nemeko yesicelo.
2,Uhlobo lwevalve yokuvala
1. Ihlelwa ngokwesakhiwo sevalvu:
a) Ngokuthe tye kwivalve yeglowubhu: Umjelo wolwelo uthe tye, unolwakhiwo olulula kunye nokumelana nokuhamba okuphantsi, okuwenza ukuba usetyenziswe ngokubanzi.
b) Ivalve yeglowubhu yeAngle: Umjelo wolwelo ukwi-engile ye-90 degree, uthatha indawo encinci kwaye ulungele iimeko ezinendawo encinci.
c) Ivalve yeglowubhu ethe ngqo: Umjelo we-fluid uthe tye kwaye unokumelana nokuhamba okuphezulu, okwenza ukuba ulungele iimeko ezinokuvulwa okuphantsi kunye nokuvala amaza.
2. Ihlelwa ngokwezixhobo zevalvu:
a) Ivalve yeglowubhu yentsimbi yeCarbon: ilungele ukusetyenziswa kwemizi-mveliso ngokubanzi kunye nemidiya efana namanzi, ioyile, umphunga, njl.
b) Ivalve yeglowubhu yentsimbi engenastainless: ilungele indawo ezineemfuno eziphakamileyo zococeko, ezinje ngolwelo oludlekayo, iigesi, iikhemikhali, njl.
c) Ivalve yeglowubhu ene-Fluorine: ilungele imeko-bume eneekhemikhali ezonakalisayo, ii-asidi ezomeleleyo, iialkalis ezomeleleyo, kunye nezinye imidiya.
3. Ihlelwa ngendlela yokuqhuba:
a) I-valve yokuvala i-valve ye-Manual: Lawula i-valve yokuvula kunye nokuvala ngokujikeleza ngesandla i-valve stem, elula kwaye kulula ukuyisebenzisa, ifanelekile kuxinzelelo oluphantsi kunye nezicelo ze-diameter encinci.
b) Ivalve yeglowubhu yombane: Ulawulo oluzenzekelayo luphunyezwa ngokuqhuba isiqu sevalve ukujikeleza ngemoto yombane, efanelekileyo kuxinzelelo oluphakathi kunye noluphezulu, usetyenziso lwedayamitha enkulu.
c) I-valve ye-pneumatic globe: Iqhutywa ngoxinzelelo lomoya ukujikeleza i-valve stem, ukufezekisa ulawulo oluzenzekelayo, olufanelekileyo kuxinzelelo oluphakathi kunye noluphezulu, iimeko ezinkulu zobubanzi.
3,Iimeko zokusetyenziswa kweevalvu zeglowubhu
1. Inkqubo yonikezelo lwamanzi: isetyenziselwa ukunqumla imithombo yamanzi, ukuphumeza ukuqaliswa kwenkqubo, ukuvalwa, kunye nokugcinwa.
2. Imboni yepetrochemical: isetyenziselwa ukunqumla imidiya eyahlukeneyo, njengeoli, igesi, amanzi, njl., Ukuqinisekisa ukhuseleko lwemveliso.
3. Ishishini lokuvelisa amandla e-Thermal: lisetyenziselwa ukunqumla imidiya efana namanzi ashushu kunye nomphunga, ukuqinisekisa ukusebenza ngokukhuselekileyo kweebhoyila kunye nezixhobo ze-thermal.
4. Ishishini lokutya kunye nesiselo: lisetyenziselwa ukunqumla imidiya efana nokutya kunye neziselo, ukuqinisekisa ukucoceka kwendawo yokuvelisa.
5. Umzi-mveliso wamachiza: usetyenziselwa ukusika izinto ezikrwada zamayeza, amayeza, kunye nolunye uhlobo losasazo ukuhlangabezana neemfuno ezingqongqo zemveliso.
6. Imboni yokukhusela indalo: isetyenziselwa ukunqumla imithombo yeendaba ezifana nogutyulo kunye ne-sludge, kunye nokufezekisa ukusebenza okuqhelekileyo kweendawo zokukhusela indalo.
4,Imigqaliselo yokukhetha iivalvu zokuvala
1. Khetha imathiriyeli yevalvu efanelekileyo ngokweempawu zesiphakathi (ezifana nokuhlwa, ubushushu, uxinzelelo, njl. njl.).
2. Khetha imodeli yevalvu efanelekileyo ngokoxinzelelo loyilo, ubushushu boyilo, kunye nobubanzi bombhobho.
3. Qwalasela imo yokuqhuba ivalve kwaye ukhethe iivalve ze-manual, zombane, okanye ze-pneumatic zokuvala ezisekelwe kwiimeko zesayithi kunye neemfuno.
4. Cinga indawo yokufakela kunye nolwalathiso lwevalve ukuqinisekisa ukusebenza kwayo okuqhelekileyo.
5. Khetha iivalve eziveliswe ngabavelisi abahloniphekileyo ukuqinisekisa umgangatho kunye nenkonzo yokuthengisa emva kweevalve.
Ngamafutshane, ukhetho oluchanekileyo lwee-valve zokuvala ludinga ukuqwalaselwa ngokupheleleyo kweempawu ze-medium, iiparameters zoyilo lombhobho, kunye neemeko zesicelo. Ndiyathemba ukuba esi sikhokelo siluncedo kuwe.
