Izimiso Zokukhethwa Kwe-Valve Nezinyathelo Zokukhetha i-Valve

Isimiso sokukhetha i-Valve
(1) Ukuphepha Nokwethenjwa. I-petrochemical, isiteshi samandla, metallurgy kanye nezinye izidingo zokukhiqizwa kwezimboni zokusebenza okuqhubekayo, okuzinzile, okuhlala isikhathi eside. Ngakho-ke, i-valve edingekayo kufanele ibe ngcono kakhulu, isici esikhulu sokuphepha, ayinakubangela ukuphepha okukhulu kokukhiqiza kanye nokulimala komuntu ngenxa yokuhluleka kwe-valve, ukufeza izidingo zokusebenza isikhathi eside sedivayisi. Ngaphezu kwalokho, ukunciphisa noma ukugwema ukuvuza okubangelwa ama-valves, dala ifektri ehlanzekile, ephucukile, ukwenziwa kwezempilo, ukuphepha, ukuphathwa kwemvelo.

(2) Hlangana nezidingo zokukhiqizwa kwenqubo. I-valve kufanele ihlangabezane nezidingo zokusebenzisa i-medium, ukucindezela, izinga lokushisa nokusetshenziswa, okubuye kube yisidingo esiyisisekelo sokukhethwa kwe-valve. Uma i-valve iyadingeka ukuvikela ukweqiwa ngokweqile nokukhipha okuphakathi nendawo, i-valve yezokuphepha ne-valve echichimayo izokhethwa; Ukuvimbela i-medium Return valve ngesikhathi senqubo yokusebenza, yamukelwaBheka i-valve; Susa ngokuzenzakalela amanzi ama-condensate, umoya kanye nolunye uphethiloli olwenziwe nge-Steam Pipe nasezintweni zokusebenza, ngenkathi uvimbela ukuphunyuka kwesitemu, i-valve ye-drain izosetshenziswa. Ngaphezu kwalokho, lapho i-medium iyonakaliswa, kufanele ikhethwe izinto zokumelana nokugqwala okuhle kufanele zikhethwe.

(3) Ukusebenza okulula, ukufakwa nokulungiswa. Ngemuva kokuthi i-valve ifakiwe, opharetha kufanele akwazi ukukhomba kahle indlela ye-valve, ukuvula uphawu kanye nesibonakaliso senkomba, ukuze abhekane namaphutha ahlukahlukene aphuthumayo. Ngasikhathi sinye, isakhiwo sohlobo lwe-valve esikhethiwe kufanele sifinyelele ngangokunokwenzeka, ukufakwa okulula nokulungisa.

(4) Umnotho. Ngaphansi kwesisekelo sokuhlangabezana nokusetshenziswa okujwayelekile kwamaphayiphu enqubo, ama-valve anezindleko eziphansi zokwenziwa kanye nesakhiwo esilula kufanele akhethelwe ngangokunokwenzeka ukunciphisa izindleko zedivayisi, gwema ukungcola kwezindleko ze-valve raw kanye nokulungiswa esiteji esizayo.

Izinyathelo Zokukhetha i-Valve
1.Determine isimo sokusebenza se-valve ngokuya ngokusetshenziswa kwe-valve kudivayisi noma ngepayipi. Isibonelo, ukusebenza okuphakathi nendawo, ukucindezela kokusebenza kanye nokushisa okusebenzayo, njll.

2.Determine izinga lokusebenza lokuzama ukubekeka kwe-valve ngokuya nge-medium medium, esebenza kuyo kanye nezidingo zomsebenzisi.

3.Detatine uhlobo lwe-valve nemodi yokushayela ngokwenhloso ye-valve. Izinhlobo ezifanai-valve ye-butterfly, hlola i-valve, i-valve valve,ukulinganisa i-valve, njll. Imodi yokushayela enjenge-Worm Wheel Worm, Electric, Pneumatic, njll.

I-4.According to the parameter ye-valve. Ingcindezi yokuqothuka kanye nosayizi we-valve izofaniswa nepayipi lenqubo elifakiwe. Amanye ama-valves anquma usayizi we-valve ngokwezinga lokugeleza noma ukukhishwa kwe-valve ngesikhathi esilinganiselwe sesikhathi esiphakathi.

5.Determine ifomu lokuxhumeka le-valve ukuphela komhlaba kanye nepayipi ngokuya ngezimo zangempela zokusebenza nosayizi we-valve. Njenge-flange, i-welding, isiqeshana noma intambo, njll.

I-6.Detinermine ukwakheka kanye nefomu lohlobo lwe-valve ngokuya ngesikhundla sokufaka, isikhala sokufaka, nosayizi we-valve. Njenge-valve ye-run rod gate valve, angle ganve valve, i-valve yebhola elimisiwe, njll.

Ngokusho kwezimpawu ze-Medium, Pressure Pressure kanye nokushisa okusebenzayo, ekukhetheni okulungile nokunengqondo kwegobolondo le-valve kanye nezinto zangaphakathi.
