Ivalve sisixhobo esiqhele ukusetyenziswa kwizityalo zamandla. Isebenza ngomqheba okanye ivili lesandla. Ngaphantsi kweemeko eziqhelekileyo, ukujikeleza kwesiphatho kunye ne-handwheel clockwise kuchazwa njengendlela yokuvala, kwaye ukujikeleza kwe-counterclockwise kuchazwa njengendlela yokuvula. Nangona kunjalo, isalathiso sokuvula kunye nokuvala ezinye iivalve zichasene nale ngasentla, kwaye kufuneka ubeke ingqalelo ukujonga iimpawu zokuvula nokuvala ngaphambi kokuba usebenze.
Kumsebenzi oqhelekileyo, ukuba awuyihoyi indlela yokusebenza echanekileyo, iya kubangela umonakalo wevalve ngaphambi kwexesha kwaye ibangele ingozi. Ukuziqhelanisa kubonakalise ukuba ukusebenza ngendlela engeyiyo kwesivalo kunokonakalisa ngokulula ivili lesandla sesivalo kunye nomqheba, ukukrwela isiqu sevalve kunye nomphezulu wokutywina, okanye kude kutyumze umphezulu wokutywina, kubangele ukonakala kwevalvu, okuya kuba nempembelelo enkulu kwimveliso eqhelekileyo yesixhobo sombane.
Ukusebenza kwevalvu ngesandla:
1. Isitshixo esifanelekileyo kufuneka sisetyenziswe ekusebenzeni kwevalvu yezandla. Kuvinjelwe ngokungqongqo ukusebenzisa i-valve encinci kunye ne-wrench enkulu, kwaye i-valve enkulu iqhutywe nge-wrench encinci. Kunqatshelwe ngokungqongqo ukongeza i-stiffener kwi-wrench.
2. Yima kwicala lesandla sevalve xa usebenzisa ivalve. Akuvumelekanga ngokungqongqo ukuma kwicala elijongene nesiqu sevalve ukunqanda indawo ephakathi kumbhobho ekuvuzeni ekupakishweni kwevalve kwaye yenzakalise abantu.
3. Sebenzisa isitshixo ukusebenzisa umnyango wesandla. Ngaphambi kokusebenza, isitshixo kunye nevili lesandla sevalvu kufuneka zitshixelwe ngokuqinileyo ukuthintela ukwenzakala okubangelwa kukutyibilika. (Ingakumbi ukuma emhlabeni onokutyibilika)
4. Umsebenzi kufuneka wenziwe ngamandla engalo, kwaye kunqatshelwe ngokungqongqo ukuthembela kubunzima bomzimba ukukhusela i-wrench ekuphumeni nasekuweni.
5. Xa i-valve yokusebenza ye-asidi kunye nemibhobho ye-alkaline, kukho ithuba lokuvuza kwenkqubo. Iivalvu ezinxibelelana ngokuthe ngqo nee-asidi kunye neealkali kufuneka zinxibe iimpahla zokhuselo lwabasebenzi ezikhusela ukonakaliswa kweasidi kunye nealkali, kwaye zibe nabasebenzi abakhethekileyo bokubeka iliso kwaye bathathe amanyathelo okuthintela.
6. Ukusebenza kwevalve yesampulu yesoda nganye kufuneka kwenziwe ngesandla. Akuvumelekanga ngokungqongqo ukusebenzisa i-wrench. Iiglavu kufuneka zinxitywe ngexesha lomsebenzi ukuthintela ukutsha. Ukuba kukho indawo evuzayo, iimpahla ezingatshiyo kufuneka zinxitywe.
7. Ukusebenza kocango oluphindwe kabini lwempompo yamanzi kwibhoyili kufuneka kwenziwe ngesandla, kwaye ii-handwheels ezimbini kufuneka zitshintshwe.
8. Ngethuba lotyando, ukuba luvakala lunzima, buyela emva kwaye uphinde wenze kwakhona, kwaye ngokutshintshana usebenze de kuvulwe okanye kuvalwe ivalve.
