Izinto ezine ezithintelwayo zokufakelwa kweevalvu

1. Uvavanyo lwe-hydrstatic kubushushu obuphantsi ngexesha lokwakha ebusika.

Iziphumo: kuba ityhubhu iqanda ngokukhawuleza ngexesha lovavanyo lwe-hydraulic, ityhubhu iyaqanda.

Amanyathelo: zama ukwenza uvavanyo lwe-hydraulic ngaphambi kokusetyenziswa ebusika, kwaye emva kovavanyo loxinzelelo ukuze uvuthele amanzi, ingakumbi amanzi akwivalvu kufuneka asuswe kwinethi, kungenjalo ivalvu ingumhlwa omncinci, iqhekeke kakhulu. Le projekthi kufuneka yenziwe ebusika, phantsi kobushushu obuphakathi ngaphakathi, kwaye amanzi kufuneka avuthelwe acoceke emva kovavanyo loxinzelelo.

2. Indlela yokufaka ivalvu ayilunganga.

Umzekelo, indlela yokuhamba kwevalvu yokukhangela ichasene nophawu, isiqu sifakelwe ezantsi, ivalvu yokukhangela efakwe ngokuthe tye ifakwe ngokuthe nkqo, akukho ndawo ivulekileyo okanye ivaliweyo, kwaye isiqu sevalvu efihliweyo asijonganga emnyango wokuhlola.

Iziphumo: ukusilela kwevalvu, ukugcinwa kweswitshi kunzima, kwaye umngxuma wevalvu ojonge ezantsi udla ngokubangela ukuvuza kwamanzi.

Imilinganiselo: ngokungqongqo ngokwemiyalelo yokufakela ivalvu yokufakela, ivalvu yesango lentonga evulekileyo ukugcina ukuphakama kokuvulwa kwesiqu sevalvu, ivalvu yebhabhathane iqwalasela ngokupheleleyo indawo yokujikeleza kwesibambo, zonke iintlobo zentonga yevalvu azinakuba ngaphantsi kwendawo ethe tye, ingasathethwa ke ngokuhla. Ivalvu efihliweyo ayifanele imisele kuphela ucango lokuhlola ukuze luhlangabezane nokuvulwa nokuvalwa kwevalvu, kodwa isiqu sevalvu kufuneka sijonge ucango lokuhlola.

3. Iinkcukacha kunye neemodeli zevalvu efakiweyo azihlangabezani neemfuno zoyilo.

Umzekelo, uxinzelelo oluqhelekileyo lwevalvu lungaphantsi koxinzelelo lovavanyo lwenkqubo; ivalvu yesango yombhobho wamanzi okutya xa ububanzi bombhobho bungaphantsi okanye bulingana ne-50mm; i-dry kunye ne-risers zokufudumeza amanzi ashushu; kwaye umbhobho wokufunxa umbhobho womlilo usebenzisa ivalvu yebhabhathane.

Iziphumo: zichaphazela ukuvulwa nokuvalwa okuqhelekileyo kwevalvu kwaye zilungelelanise ukumelana, uxinzelelo kunye neminye imisebenzi. Nokuba ibangele ukusebenza kwenkqubo, umonakalo wevalvu uyanyanzeleka ukuba ulungiswe.

Amanyathelo: Yazi ububanzi bokusetyenziswa kweevalvu ezahlukeneyo, kwaye ukhethe iinkcukacha kunye neemodeli zeevalvu ngokweemfuno zoyilo. Uxinzelelo oluqhelekileyo lwevalvu kufuneka luhlangabezane neemfuno zoxinzelelo lovavanyo lwenkqubo. Ngokwekhowudi yokwakha: ivalvu yokumisa mayisetyenziswe xa ububanzi bombhobho bungaphantsi okanye bulingana ne-50mm; ivalvu yesango mayisetyenziswe xa ububanzi bombhobho bungaphezulu kwe-50mm. Ivalvu yokulawula eshushu yomile, ethe nkqo mayisetyenziswe ivalvu yesango, iphayiphi yokufunxa amanzi omlilo akufuneki isebenzise ivalvu yebhabhathane.

4. Ukufakelwa kweevalvu ngendlela engafanelekanga kwindawo enobushushu obuphezulu.

Iziphumo: kubangela ingozi yokuvuza

Imilinganiselo: ivalvu yobushushu obuphezulu engaphezulu kwama-200℃, kuba ukufakelwa kubushushu obuqhelekileyo, kwaye emva kokusetyenziswa okuqhelekileyo, ubushushu buyanyuka, i-bolt iyandisa ubushushu, umsantsa uyanda, ngoko ke kufuneka iqiniswe kwakhona, ebizwa ngokuba yi-"hot tight", abaqhubi kufuneka banikele ingqalelo kulo msebenzi, kungenjalo kulula ukuvuza.
