China jonga amanyathelo ofakelo lwevalvu eneenkcukacha: indawo yofakelo, isalathiso kunye nezilumkiso
China itshekhi valve sisixhobo sokulawula ulwelo esisetyenziswa ngokuqhelekileyo, kwaye amanyathelo ayo ofakelo abalulekile ukuqinisekisa ukusebenza okuqhelekileyo kwesixhobo. Eli nqaku liza kukunika inkcazo eneenkcukacha zamanyathelo ofakelo lwe-valve yokujonga i-China ukusuka kwindawo yokujonga, kubandakanywa indawo yokufakela, isikhokelo kunye nezilumkiso.
1. Qinisekisa indawo yokufakela
Okokuqala, kufuneka siqonde indawo yokufakela i-valve yokutshekisha yaseTshayina. Ngokuqhelekileyo, i-valve yokutshekisha yaseTshayina kufuneka ifakwe ekungeneni okanye ekuphumeni kombhobho ukulawula ulwalathiso kunye nokuhamba kwamanzi. Xa ukhetha indawo yokufakela, le miba ilandelayo kufuneka iqwalaselwe:
(1) Ubume bombhobho: Indawo apho uyilo lombhobho lufanelekile kwaye kulula ukulugcina lufanele lukhethwe.
(2) Isalathiso sokuhamba kolwelo: Indawo yofakelo efanelekileyo kufuneka ikhethwe ngokwendlela yokuhamba kolwelo olukumbhobho. Ngokomzekelo, xa i-medium ihamba ngendlela enye, i-valve yokutshekisha yaseTshayina kufuneka ifakwe kwindawo yokungena; Xa i-medium yi-bidirectional flow, i-valve yokutshekisha yaseTshayina ingafakwa kumbhobho kumacala omabini.
(3) Uxhulumaniso lwezixhobo: Indlela yokudibanisa kunye nezinye izixhobo kufuneka ithathelwe ingqalelo ukuze kuqinisekiswe ukulungelelaniswa okulungileyo phakathi kwe-valve yokutshekisha yaseTshayina kunye nenkqubo yombhobho.
2. Qinisekisa ulwalathiso lofakelo
Emva kokumisela indawo yokufakela, kuyafuneka kwakhona ukugqiba isalathiso sokufakela i-valve yokutshekisha yaseTshayina. Ngokubanzi, ukufakela kufuneka kwenziwe ngokuhambelana nale migaqo ilandelayo:
(1) Ufakelo oluthe tye: Ukuba iIvalve yokuhlola yaseTshayinaifakwe ngokuthe tye, indawo eyaneleyo kufuneka igcinwe emhlabeni ukuze igcinwe kwaye ilungiswe.
(2) Ufakelo oluthe nkqo: Ukuba iChina itshekhi valveifakwe ngokuthe nkqo, kufuneka kuqinisekiswe ukuba ukuphakama kwendawo yokufakela kuhlangabezana neemfuno zoyilo, kwaye amanyathelo okulungisa ahambelanayo kufuneka athathwe.
(3) Ufakelo olusezantsi: Ukuba iChina itshekhi valveUfakelo luthambekele, ingqalelo kufuneka ihlawulwe kubungakanani kunye nolwalathiso lwe-Angle ethambekileyo ukuze kuqinisekiswe ukuba i-valve yokutshekisha yaseChina inokusebenza ngokuqhelekileyo.
3. Nika ingqalelo kwiinkcukacha zofakelo
Xa ufaka i-valve yokutshekisha yaseTshayina, kufuneka uhlawule ingqalelo kwezi nkcukacha zilandelayo:
(1) Ukuqinisekisa ukusebenza kokutywinwa: Ngexesha lenkqubo yokufakela, ingqwalasela kufuneka ihlawulwe ekusebenzeni kokutywinwa phakathi kwevalve kunye nombhobho ukuqinisekisa ukuba i-valve yokutshekisha yaseChina ingasebenza ngokuqhelekileyo.
(2) Naka ingqalelo kwi-wiring yamandla: Ukuba i-valve yokujonga i-China idinga umqhubi wamandla, nikela ingqalelo kwi-wiring echanekileyo kwaye uthathe amanyathelo ayimfuneko okhuseleko.
(3) Ukuthintela ukuhamba kwe-reverse: Ngethuba lenkqubo yokufakela, kufuneka kuhlawulwe ingqalelo ukuze kuthintelwe ukwenzeka kwe-reverse flow, ukuze kungachaphazeli ukusebenza okuqhelekileyo kwe-valve yokujonga i-China.
Ngamafutshane, amanyathelo okufakela i-valve yokujonga i-China iquka ukumisela indawo yokufakela, ulwalathiso kunye nezilumkiso. Ngethuba lofakelo, kufuneka lulungiswe kwaye luqhutywe ngokwemeko ethile ukuqinisekisa ukusebenza okuqhelekileyo kunye nobomi benkonzo yezixhobo. Ndiyathemba ukuba eli nqaku lichaze amanyathelo ofakelo lwe-valve yokujonga i-China ngokweenkcukacha, kwaye inokukunika ireferensi kunye noncedo.
