Umahluko Phakathi kweValve yokuVala ngokukhawuleza kunye neValve yokuZivala

Kwiinkqubo zaselwandle nakwimizi-mveliso, ukhuseleko kunye nokusebenza kakuhle kuxhomekeke ekubeni ivalvu inokusabela ngokukhawuleza kangakanani kwimeko engxamisekileyo. Iindidi ezimbini zeevalvu ezidla ngokubhidaniswa zeziivalvu yokuvala ngokukhawulezakwaye iivalvu ezivala ngokwayoNangona amagama azo evakala efana, ulwakhiwo lwazo, imigaqo yokusebenza, kunye nokusetyenziswa kwazo kwahlukile. Ukuqonda umahluko kunceda ukuqinisekisa ukuba ivalvu efanelekileyo isetyenziswa kwinkqubo efanelekileyo.

Yintoni iValve yokuvala ngokukhawuleza

Ivalvu yokuvala ngokukhawuleza yenzelwe ukuvala ukuhamba kolwelo okanye igesi ngoko nangoko xa kukho imeko engxamisekileyo. Ixhaphake kakhulu kwimibhobho yeoyile yepetroli yaselwandle, kwiinkqubo zokuthambisa, nakwiindawo zeenjini apho impendulo ekhawulezileyo ibalulekile ukuthintela umlilo okanye ukuvuza.

Ivalvu isebenza ngesixhobo sokulawula kude—ngokuqhelekileyo ucingo okanye i-lever eqhagamshelwe kwisibambo esingaphandle kwegumbi lenjini. Xa itsalwa, iyayikhulula ivalvu, ivumela ukuba ivale ngokukhawuleza ngamandla entwasahlobo. Olu phawu luvumela amalungu eqela ukuba ahlukanise inkqubo yepetroli ngoko nangoko ngaphandle kokungena kwindawo enobungozi.

Iimpawu eziphambili zeeValve zokuvala ngokukhawuleza

• ①Isebenza kude ukuze ikhuseleke xa kukho umlilo okanye ukuvuza.

• ②Ivala ngoko nangoko ukuze kunqunyulwe ulwelo.

• ③Ngokuqhelekileyo ifakwa entwasahlobo okanye incediswa yi-pneumatic.

• ④Yenziwe ngebronze okanye ngentsimbi engatyiwayo ukuze isetyenziswe elwandle.

• ⑤Ifakwe kwiitanki zenkonzo yeoyile yepetroli, kwiitanki zedizili, nakwiintambo zeoyile zehydraulic.

Iivalvu zokuvala ngokukhawuleza ziyinxalenye ebalulekileyo yeenkqubo zokhuseleko lwaselwandle. Kwiimeko ezingxamisekileyo, zinceda ekuthinteleni ukusasazeka komlilo kwaye zinciphise umonakalo, zikhusela abasebenzi kunye nezixhobo.

Yintoni iValve eZivalayo

Kwelinye icala, ivalvu ezivala ngokwayo ivala ngokuzenzekelayo emva kokusebenza ngaphandle kokufuna amandla angaphandle okanye ulawulo olukude. Yenzelwe iinkqubo ezifuna ukuyeka ukuhamba kolwelo ngokuzenzekelayo emva kokuba ukuzaliswa okanye ukutsalwa kwamanzi kugqityiwe.

Uhlobo oluqhelekileyo yivalvu yokubuyisela intwasahlobo, apho isiphatho kufuneka sibanjwe sivulekile ngesandla. Nje ukuba sikhutshwe, indlela yentwasahlobo inyanzela ivalvu ukuba ivale. Ezi valve zihlala zifumaneka kwiindawo zokugcwalisa ipetroli, kwiindlela zokukhupha amanzi, nakwiindawo zokukhupha amanzi kwiinqanawa nakwizixhobo zoshishino.

Iimpawu eziphambili zeeValve ezizivalayo

• ①Ivala ngokuzenzekelayo xa isiphatho sikhululiwe.

• ②Ithintela ukuzaliswa kakhulu ngengozi okanye ukukhutshwa rhoqo.

• ③Isakhiwo esilula, kulula ukuyisebenzisa nokuyigcina ikwimeko entle.

• ④Ilungele izitishi ze-bunker, imigca yokuhambisa ipetroli, kunye neenkqubo zokukhupha amanzi kwidekhi.

Nangona kungenzelwanga ukuvalwa kwezixhobo ngexesha likaxakeka, iivalvu ezizivalayo zonyusa ukhuseleko lokusebenza kwaye zinciphisa umngcipheko wokuchitheka kwezixhobo ngexesha lemisebenzi eqhelekileyo.
