Kufuneka ndenze ntoni ukuba ivalve yokukhangela ayikwazi ukumisa amanzi?

Andikwazikhangela ivalveukumisa amanzi? Ezi ndlela ziya kukunceda ukusombulula

Iivalvu zokujonga kufuneka zibe "ngabagcini abathembekileyo" ukuthintela ukubuya kwamanzi, kodwa xa bengaphumeleli ukumisa amanzi, kunokubangela ingxaki enkulu. Nangona kunjalo, ungakhathazeki, sinokuphanda kwaye siyisombulule ingxaki kwimiba emininzi.

Inkqubo yofakelo kufuneka ijongwe kuqala.Khangela iivalvuYiba neempawu ezicacileyo zendlela yokuhamba kwamanzi. Ukuba ifakwe kwicala elingalunganga, kufana nokukhomba "indlela yokubuyisela" kumpompozo wamanzi, kwaye amanzi aya kubuyela umva ngokwendalo. Kweli nqanaba, jonga nje ngononophelo iimpawu zotolo kwivalve kwaye uyibuyisele kwicala elichanekileyo. Ukongezelela, indawo yokufakela i-valve yokutshekisha ifuna ingqwalasela. Ukuba ifakwe kwi-bend yombhobho okanye kufuphi nokuphuma kompompo wamanzi, imeko yokuhamba kwamanzi iya kuba nzima kwaye impembelelo yempembelelo iya kuba nkulu, eya kuchaphazela ukusebenza kwayo ngokuqhelekileyo. Kufuneka ifakwe kumbhobho wokuhamba kwamanzi othe tye kunye nozinzileyo, kude namagophe kunye neendawo zokumpompa, ukudala indawo yokusebenza efanelekileyo kuyo.

Umonakalo wecandelo kwakhona ngunobangela oqhelekileyo. Idiskhi yevalvu kunye nesitulo sevalvu zizinto eziphambili zokuphumeza ukutywinwa kwiivalvu zokutshekisha. Ukuba idiski yevalvu igugile kakhulu kwaye ayinakho ukulingana ngokuqinileyo nesitulo sevalve, amanzi aya kuvuza ngesikhewu. Ngokufanayo, ukuguqulwa kwesitulo sevalve kunokuchaphazela umphumo wokutywinwa. Kwiingxaki ezinjalo, ukuba iqondo lokugqoka okanye ukuguqulwa lilula, izixhobo zokugaya zingasetyenziselwa ukugaya ngokucokisekileyo indawo yokutywina ukubuyisela ukunyameka kunye nokugudiswa; Ukuba umonakalo unzima, idisk yevalve entsha okanye isitulo kufuneka sitshintshwe. Ukungaphumeleli kwentwasahlobo akunakunakwa. Inoxanduva lokutsala kwangethuba idiski yevalve umva kwindawo evaliweyo xa ukuphuma kwamanzi kuyeka. Ukuba ukukhathala kwentwasahlobo, ukugqwala, kunye nokulahlekelwa kwe-elasticity, i-disc valve ayikwazi ukuvalwa ngexesha. Ngeli xesha, intwasahlobo entsha eneenkcukacha ezifanayo njengentwasahlobo yasekuqaleni idinga ukutshintshwa.

Umba ophakathi usenokubangela ukusilela kwekhangela ivalve. Ukuba amanzi aqulethe isixa esikhulu sokungcola okufana nentlenga, umhlwa, njl. njl., obu kungcola kuya kuxinga phakathi kwediski yevalvu kunye nesitulo sevalve, kuthintele idiski yevalve ekuvaleni. Isihluzi sinokufakwa phambi kwevalve yokutshekisha, kwaye isikrini sokucoca kufuneka sicocwe rhoqo ukunciphisa ukungcola ekungeneni kwevalve. Ukongezelela, ukushisa kunye noxinzelelo lwamanzi kunokuchaphazela nokusebenza kwee-valve zokujonga. Ukuba idlula uluhlu lwayo olulinganisiweyo, amanyathelo okulungelelaniswa ahambelanayo kufuneka athathwe, njengokufakela iivalve zokunciphisa uxinzelelo okanye izixhobo zokupholisa.
