Ngokuthuthuka okuqhubekayo kokwakhiwa kobunjiniyela, ama-valve, njengemishini ebalulekile yokulawula ukugeleza, kancane kancane abe yingxenye ebalulekile yezimboni ezihlukahlukene. Indlela yokukhetha ama-valve ekhwalithi ephezulu ahlangabezana nezidingo sekuyinkinga abanikazi abaningi abakhathazeke ngayo futhi abakhathazeke ngayo. Namuhla, sizokunikeza isayensi ethandwayo ukuthi ungakhetha kanjani ama-valve ekhwalithi ephezulu akhiqizwa abakhiqizi be-valve base-Tianjin.
Okokuqala, qaphela izinto ze-valve. Izimboni ezahlukene kanye namaphrojekthi adinga izinto ezahlukene ze-valve, ngakho-ke kubaluleke kakhulu ukukhetha impahla efanele ngokuvumelana nezidingo zangempela. Ngokuvamile, izinto ze-valve zihlanganisa insimbi ekhonjiwe, i-carbon steel, insimbi engagqwali, njll., lapho ama-valve ensimbi engenasici asetshenziswa kabanzi embonini yamakhemikhali, yokudla, yezemithi kanye nezinye. Ngenxa yokuthi i-valve yensimbi engenasici inokumelana nokugqwala okuhle kakhulu, ingaqinisekisa ukusebenza okuzinzile kwesikhathi eside kohlelo lobunjiniyela.
Okwesibili, kufanele sinake ukusebenza kokuvalwa kwe-valve. I-valve yekhwalithi ephezulu kufanele ibe nokusebenza okuhle kakhulu kokuvala ukuze kuqinisekiswe ukunemba nokuzinza kokulawula uketshezi futhi igweme ukuvuza nokulahlekelwa ngenxa yokuvaleka kahle. Ngakho-ke, lapho uthenga i-valve ekhiqizwe ngumkhiqizi we-Tianjin Valve, kuyadingeka ukuhlola ngokucophelela impahla yokuvala, isakhiwo kanye nenqubo yokukhiqiza ye-valve ukuze kuqinisekiswe ukuthi ihlangabezana nezindinganiso ezifanele kanye nezidingo.
Nakulokhu, qaphela ukuqina kwe-valve. Ukuqina kwe-valve akuxhomeki kuphela ekukhethweni kwezinto zokwakha, kodwa futhi kuhlobene kakhulu nokunemba kwemishini kanye nenqubo yokukhiqiza. Ngakho-ke, khetha i-valve ekhiqizwe umkhiqizi we-valve we-Tianjin, kufanele sicabangele ngokucophelela inqubo yayo yokukhiqiza, ukunemba kwemishini, ukuqinisekiswa kwekhwalithi kanye nesevisi yangemuva kokuthengisa, njll., ukuqinisekisa ukuthi i-valve ingasebenza ngokuzinzile isikhathi eside.
Okokugcina, kufanele futhi sinake imodi yokulawula ye-valve. Imodi yokulawula ye-valve ihlukile, uma imodi yokulawula ingakhethiwe, ingase iholele ekuhlulekeni kwe-valve, ukusebenza okungalungile nezinye izinkinga. Ngakho-ke, lapho ukhetha ama-valve ekhwalithi ephezulu akhiqizwa abakhiqizi be-Tianjin Valve, izinhlobo ezahlukene ze-actuator, izindlela zokusebenza kanye nezinhlelo zokulawula zidinga ukukhethwa ngokuvumelana nezidingo zangempela zokuqinisekisa ukulawula okunembile nokusebenza kahle kwama-valve.
Ngamafuphi, ukukhethwa kwama-valve ekhwalithi ephezulu kudinga ukucabangela izici eziningi, njengezinto ezibonakalayo, ukusebenza kokuvala, ukuqina nezindlela zokulawula, futhi kudingeka futhi baqonde umthamo wokukhiqiza kanye nenkonzo yangemuva yokuthengisa yabakhiqizi be-valve ye-Tianjin ukuqinisekisa ukuthi ama-valve akhethiwe angahlangabezana nezidingo zangempela kanye nokusebenza okuzinzile kwesikhathi eside. Ngithemba ukuthi lesi sihloko singakusiza ukuthi ukhethe kangcono ama-valve ekhwalithi ephezulu akhiqizwaUmkhiqizi we-Tianjin Valve e-China.
