Ivalve yebhola yePVCyivalve eyenziwe ngezinto zePVC, ezisetyenziselwa ukusika okanye ukudibanisa imidiya kwimibhobho, kunye nokulawula nokulawula ulwelo. Olu hlobo lwevalve lusetyenziswe kumashishini amaninzi ngenxa yobunzima bayo kunye nokuxhathisa okuqinileyo kwe-corrosion. Oku kulandelayo kuya kunika intshayelelo eneenkcukacha kwisakhiwo esisisiseko kunye neempawu zePVC iivalvu zebhola zeplastiki.
1. Umzimba weValve
Umzimba wevalvu lelinye lawona malungu aphambiliIivalvu zebhola zePVC, eyenza isakhelo esisisiseko se-valve yonke. Umzimba wevalvu yevalve yebhola ye-PVC udla ngokwenziwa ngezinto zePVC, ezinokumelana ne-corrosion elungileyo kwaye zinokuqhelana nonyango lwemithombo yeendaba eyonakalisayo. Ngokweendlela ezahlukeneyo zokudibanisa, iivalvu zebhola zePVC zinokwahlulwa zibe ziindidi ezahlukeneyo ezifana noqhagamshelo lweflange kunye noqhagamshelo olunentambo.
2. Ibhola yevalve
Ibhola yevalve ibekwe ngaphakathi kumzimba wevalve kwaye iyinxalenye engqukuva, eyenziwe ngemathiriyeli yePVC. Lawula ukuvuleka kunye nokuvala okuphakathi ngokujikelezisa ibhola yevalve. Xa umngxuma kwibhola yevalve ihambelana nombhobho, i-medium ingadlula; Xa ibhola yevalve ijikeleza kwindawo evaliweyo, ubuso bayo buya kuvala ngokupheleleyo indlela yokuhamba okuphakathi, ngaloo ndlela ifezekisa umphumo wokutywinwa.
3. Isihlalo seValve
Isihlalo sevalve yinxalenye ephambili edibana nebhola yevalve kwaye ibonelela ngesiphumo sokutywinwa. Kwiivalvu zebhola zePVC, isihlalo sevalve senziwa ngokubanzi ngemathiriyeli yePVC kwaye iyilwe ngesakhiwo segroove engqukuva ehambelana nebhola yevalve. Oku kunokwenza umsebenzi wokutywina kakuhle xa ibhola yevalve idityaniswe ngokuqinileyo kwisitulo sevalve, ukuthintela ukuvuza okuphakathi.
4. Umsesane wokutywina
Ukuze kuphuculwe ngakumbi ukusebenza kokutywinwa, iivalvu zebhola zeplastiki zePVC nazo zixhotyiswe ngamakhonkco okutywina. Ezi zindandatho zokutywina zihlala zenziwe ngezinto ezifana ne-EPDM okanye i-PTFE, engaqinisekanga kuphela ukusebenza kakuhle kokutywinwa, kodwa inokumelana nokutshintsha kobushushu phakathi koluhlu oluthile.
5. I-Arhente eLawulayo
NgombaneIivalvu zebhola zePVC, ngaphezu kwamacandelo asisiseko akhankanywe ngasentla, kukho kwakhona inxalenye ebalulekileyo - i-actuator yombane. I-actuator yombane ibandakanya amacandelo afana neenjini, iiseti zegiya, kunye neevalvu ze-solenoid, ezinoxanduva lokuqhuba ibhola yevalve ukujikeleza kunye nokulawula imeko yokuhamba kwendawo. Ukongeza, ii-actuator zombane zinokuxhasa ulawulo olukude oluzenzekelayo, okwenza ukusebenza kwenkqubo yonke kube lula ngakumbi kwaye kusebenze.
6. Indlela yoqhagamshelwano
Iivalvu zebhola zePVCukuxhasa iindlela ezininzi zoqhagamshelwano, kubandakanywa kodwa kungaphelelanga kwimidibaniso yentambo yangaphakathi, udibaniso lwentambo yangaphandle, udibaniso lwe-butt welding, udibaniso lwe-socket welding, kunye noqhagamshelwano lwe-flange. Ukukhethwa kwendlela yokudibanisa efanelekileyo kuxhomekeke kwimeko ethile yesicelo kunye neemfuno zobugcisa.
