Ndihlala ndidibana nemibuzo yabathengi efana nale ilandelayo: "Molo Beria, ndifuna ivalvu yesango, ungasicaphulela?" Iivalvu zesango ziimveliso zethu, kwaye siqhelene nazo kakhulu. Ixabiso alikho ngxaki, kodwa ndingamnika njani isaphulelo ngokusekelwe kulo mbuzo? Indlela yokucaphulela inokunceda abathengi bafumane iiodolo, okanye bathenge iimveliso abathengi abazidingayo? Ngokucacileyo, le datha yodwa ayanelanga. Okwangoku, ndihlala ndibuza umthengi "luhlobo luni lwevalvu yesango oyifunayo, yintoni uxinzelelo, ingakanani ubungakanani, unayo na iqondo eliphakathi kunye nobushushu?" Abanye abathengi baya kucaphuka kakhulu, ndifuna nje ixabiso, undibuza imibuzo emininzi, ukuba awungochwepheshe kangakanani. Abanye abazange babuze mibuzo, kwaye bandinike nje isaphulelo. Kodwa, ngaba ngokwenene asingochwepheshe? Ngokuchasene noko, kungenxa yokuba singochwepheshe kwaye sinoxanduva kuwe ukuba sibuze le mibuzo. Ewe, kulula ukucaphulela, kodwa akulula ukunceda abathengi bafumane iiodolo. Ngoku, makhe sihlalutye amanqaku ekufuneka anikelwe ingqalelo kumbuzo kunye nesicatshulwa seevalvu zesango ukusuka kwezi zinto zilandelayo.
Ngokubanzi, izinto ezicatshulweyo zeevalvu zesango ziquka imo (intonga evulekileyo okanye intonga emnyama), uxinzelelo, ububanzi, izinto ezisetyenziswayo, kunye nobunzima. Kweli nqaku, sixoxa kuphela ngeevalvu zesango ezitywiniweyo ezithambileyo.
1. Uhlobo: Kukho iintlobo ezimbini zeevalvu zesango ezitywiniweyo ezithambileyo, ivalvu yesango lesiqu esinyukayo kunye nevalvu yesango lesiqu esifihliweyo. Ivalvu yesango lesiqu esinyukayo ifuna indawo enkulu yokusebenza kwaye ifanelekile ngakumbi kwiiprojekthi zemibhobho emhlabeni. Isiqu sevalvu asishukumi phezulu nasezantsi, ngoko ke sifanelekile kwiiprojekthi zemibhobho engaphantsi komhlaba.
2. Uxinzelelo: Kwiivalvu zesango ezitywiniweyo ezithambileyo, uxinzelelo oluqhelekileyo olusetyenziswayo yiPN10-PN16, Class150. Nokuba uxinzelelo luphezulu kangakanani na, ipleyiti egqunywe ngerabha iya kuba nokukhubazeka. Asicebisi ukusetyenziswa kweevalvu zesango ezitywiniweyo ezithambileyo;
3. Ubungakanani: Oku kulula kakhulu, okukhona i-caliber inkulu, kokukhona ivalvu ibiza kakhulu;
4. Izinto: Ngokwezinto eziphathekayo, zineenkcukacha ezithe vetshe. Ngokwesiqhelo sithetha ngezinto eziphathekayo kwezi zinto zilandelayo, umzimba wevalvu, ipleyiti yevalvu, umngxuma; kwiivalvu zesango ezitywiniweyo ezithambileyo, izinto zomzimba wevalvu ezisetyenziswa kakhulu yi-ductile iron body. Ipleyiti yevalvu yipleyiti yerabha egqunywe yintsimbi egudileyo. Kukho iindlela ezininzi zokukhetha umngxuma wevalvu, umngxuma wentsimbi yekhabhoni, umngxuma we-2cr13, umngxuma wentsimbi engagqwaliyo, kwaye i-gland yevalvu yesango yahlukile kwi-iron gland kunye ne-brass gland. Kwi-corrosive media, ngokuqhelekileyo Kucetyiswa ukusebenzisa ii-brass nuts kunye nee-brass glands, ezingenazo ii-corrosive media, kwaye ii-iron nuts kunye nee-iron glands eziqhelekileyo zanele.
5. Ubunzima: Ubunzima apha bubhekisa kubunzima bevalvu enye, nto leyo ekwayinto elula ukuyihoya. Ngaba izinto ezisetyenzisiweyo zimiselwe, kwaye ixabiso limiselwe ivalvu yesango lobukhulu obufanayo? Impendulo imbi. Ukuze kuhlangatyezwane neemfuno ezahlukeneyo zemarike, abavelisi beevalvu benza ubukhulu beevalvu bahluke, nto leyo ebangela ukuba nokuba izinto ziyafana, ubungakanani buyafana, ubude besakhiwo buyafana, ububanzi bangaphandle beflange kunye nomgama osembindini womngxuma weflange buyafana, kodwa ubukhulu bomzimba wevalvu abufani, kwaye ubunzima bevalvu yesango lobukhulu obufanayo buya kwahluka kakhulu. Umzekelo, ivalvu yesango ye-DN100 efanayo, i-DIN F4 emnyama, sineentlobo ezi-6 zobunzima, i-10.5kg, i-12kg, i-14kg, i-17kg, i-19kg, i-21kg, ngokucacileyo, okukhona ubunzima bunzima, kokukhona ixabiso libiza kakhulu. Njengomthengi oqeqeshiweyo, kufuneka wazi ukuba imveliso oyifunayo isetyenziswa kwimeko yokusebenza enjani, umgangatho ofunekayo kumthengi, kunye nohlobo lwexabiso umthengi alwamkelayo. Kwifektri yethu, ngokuqinisekileyo sifuna abathengi bathenge iimveliso ezikumgangatho ophezulu, ukuze emva kokuthengisa kube kuncinci kakhulu. Nangona kunjalo, ngenxa yemfuno yemarike, kufuneka sahlukanise iimveliso zethu ukuze sifumane isabelo esingakumbi semarike.
Ngokuhlalutya ezi nkalo zingasentla, ndikholelwa ukuba kufuneka ube nokuqonda okungcono ngokuthenga iivalvu zesango ezitywiniweyo ezithambileyo. Ukuba usenemibuzo malunga nokuthenga iivalvu zesango, nceda unxibelelane neZhongfa Valve, kwaye siya kwenza konke okusemandleni ethu ukukunceda usombulule ezi ngxaki.
