Ulwazi lofakelo lwevalvu

Kwinkqubo yolwelo, ivalve isetyenziselwa ukulawula indlela, uxinzelelo kunye nokuhamba kolwelo. Kwinkqubo yokwakha, umgangatho wofakelo lwe-valve luchaphazela ngokuthe ngqo ukusebenza okuqhelekileyo kwixesha elizayo, ngoko kufuneka lixabiswe kakhulu yiyunithi yokwakha kunye neyunithi yokuvelisa.

Ivalve iya kufakwa ngokuhambelana nencwadana yokusebenza kwevalvu kunye nemigaqo efanelekileyo. Kwinkqubo yokwakhiwa, ukuhlolwa ngononophelo kunye nokwakhiwa kuya kwenziwa. Ngaphambi kokufakwa kwevalve, ukufakela kuya kuqhutywa emva kokuba uvavanyo loxinzelelo lufanelekile. Hlola ngokucophelela ukuba inkcazo kunye nemodeli ye-valve ihambelana nomzobo, khangela ukuba zonke iinxalenye zevalve zikwimeko efanelekileyo, nokuba i-valve yokuvula kunye nokuvala ingajikeleza ngokukhululekileyo, nokuba indawo yokutywina yonakaliswe, njl njl. emva kokuqinisekisa, ukufakwa kungaqhutywa.

Xa i-valve ifakwe, indlela yokusebenza yevalve kufuneka ibe malunga ne-1.2m kude nomhlaba wokusebenza, omele uhlanjululwe ngesifuba. Xa iziko levalve kunye nevili lesandla lingaphezulu kwe-1.8m kude nomhlaba wokusebenza, iqonga lokusebenza liya kumiselwa ivalve kunye nevalve yokhuseleko ngokusebenza ngakumbi. Kwimibhobho eneevalve ezininzi, iivalve ziya kugxininiswa kwiqonga kangangoko kunokwenzeka ukuba usebenze ngokulula.

Kwivalve enye engaphezulu kwe-1.8m kwaye ingasetyenziswa rhoqo, izixhobo ezifana nevili letsheyini, intonga yolwandiso, iqonga elishukumayo kunye neleli eshukumayo zingasetyenziswa. Xa i-valve ifakwe ngaphantsi kwendawo yokusebenza, intonga yokwandisa iya kusekwa, kwaye i-valve yomhlaba iya kusekwa kunye nomhlaba kakuhle. Ukwenzela ukhuseleko, iqula lomhlaba liya kugqunywa.

Kwisiqu sevalve kumbhobho othe tyaba, kungcono ukuya phezulu ngokuthe nkqo, kunofakelo olusezantsi lwesikhondo sevalve. I-valve stem ifakwe ezantsi, engafanelekanga ekusebenzeni nasekugcinweni, kwaye kulula ukuyidlakalisa ivalve. Ivalve yokumisa ayiyi kufakwa i-askew ukuphepha ukusebenza kakubi.

Iivalvu kumbhobho wecala necala ziya kuba nendawo yokusebenza, ukugcinwa kunye nokuqhaqha. Umgama ocacileyo phakathi kwamavili ezandla awuyi kuba ngaphantsi kwe-100mm. Ukuba umgama wombhobho umxinwa, iivalvu ziya kugxagxanyiswa.

Kwiivalve ezinamandla amakhulu okuvula, amandla aphantsi, ukunyanzeliswa okuphezulu kunye nobunzima obunzima, i-valve yokuxhasa i-valve iya kusekwa ngaphambi kokufakwa ukunciphisa uxinzelelo lokuqalisa.

Xa ufaka i-valve, iitoni zombhobho ziya kusetyenziselwa imibhobho ekufutshane nevalve, ngelixa i-spanners eqhelekileyo iya kusetyenziselwa ivalve ngokwayo. Ngexesha elifanayo, ngexesha lofakelo, i-valve iya kuba kwindawo evaliweyo yokuthintela ukujikeleza kunye nokuguqulwa kwevalve.

Ufakelo oluchanekileyo lwevalve luya kwenza ifom yesakhiwo sangaphakathi ihambelane nolwalathiso lokuhamba kwe-medium, kwaye ifom yofakelo ihambelane neemfuno ezikhethekileyo kunye neemfuno zokusebenza zesakhiwo sevalve. Kwiimeko ezikhethekileyo, nikela ingqalelo ekufakweni kweevalve ezineemfuno zokuhamba okuphakathi ngokweemfuno zenkqubo yombhobho. Ukulungiswa kwevalve kuya kuba lula kwaye kunengqiqo, kwaye umqhubi uya kuba lula ukufikelela kwi-valve. Kwivalve yesikhondo sokuphakamisa, indawo yokusebenza iya kugcinwa, kwaye izikhondo zevalve yazo zonke iivalvu ziya kufakwa phezulu kangangoko kunokwenzeka kwaye zijikeleze umbhobho.
