Umgaqo wokukhetha ivalvu
Ivalvu ekhethiweyo kufuneka ihlangabezane nale migaqo ilandelayo isisiseko.
(1) Ukhuseleko kunye nokuthembeka kwe-petrochemical, isikhululo samandla, i-metallurgy kunye nezinye izimboni kufuna ukusebenza okuqhubekayo, okuzinzileyo, nokujikeleza ixesha elide. Ke ngoko, ivalvu efunekayo kufuneka ibe nokuthembeka okuphezulu, into enkulu yokhuseleko, ayinakubangela ukhuseleko olukhulu kwimveliso kunye nokulimala komntu ngenxa yokusilela kwevalvu, ihlangabezane neemfuno zokusebenza komjikelo omde wesixhobo, kwaye imveliso eqhubekayo yomjikelo omde yinzuzo.
(2) Ukuze kuhlangatyezwane neemfuno zenkqubo yokuvelisa ivalvu kufuneka kuhlangatyezwane nokusetyenziswa koxinzelelo oluphakathi, olusebenzayo, ubushushu bokusebenza kunye neemfuno zokusetyenziswa, nto leyo ekwayimfuno esisiseko yokukhetha ivalvu. Ukuba kuyimfuneko, indima yokukhusela uxinzelelo oluphezulu lwevalvu, ukukhupha i-medium engaphezulu, kufuneka kukhethwe ivalvu yokhuseleko, ivalvu yokugcwala, kufuneka kuthintelwe inkqubo yokusebenza kwe-medium backflow, kufuneka kusetyenziswe ivalvu yokujonga, kufuneka kususwe ngokuzenzekelayo umbhobho womphunga kunye nezixhobo ze-condensate, umoya kunye nezinye izixhobo zegesi ezingakwaziyo ukufutha, kwaye ukuze kuthintelwe ukuphuma komphunga, kufuneka kukhethwe ivalvu yokukhupha amanzi. Ukongeza, xa i-medium iyinto ebolayo, kufuneka kukhethwe izixhobo ezilungileyo zokumelana nokugqwala.
(3) Emva kokusebenza, ukufakela, ukujonga (ukulungisa) ivalvu, umqhubi kufuneka akwazi ukubona ngokuchanekileyo icala levalvu, iimpawu zokuvula, imiqondiso yokubonisa, kube lula ukuyiphatha ngexesha elifanelekileyo kwaye ajongane neemeko ezahlukeneyo ezingxamisekileyo. Kwangaxeshanye, ulwakhiwo lohlobo lwevalvu olukhethiweyo kufuneka lube lula kangangoko kunokwenzeka, ukufakelwa, ukuhlolwa (ukulungisa) ukulungiswa kube lula.
(4) Uqoqosho Ngenxa yokusetyenziswa okuqhelekileyo kwemibhobho yenkqubo, iivalvu ezinexabiso eliphantsi lokuvelisa kunye nesakhiwo esilula kufuneka zikhethwe kangangoko kunokwenzeka ukunciphisa iindleko zesixhobo, kuthintelwe inkcitho yezinto ezikrwada zeevalvu kunye nokunciphisa iindleko zokufakela kunye nokugcinwa kweevalvu kwinqanaba elilandelayo.
Amanyathelo okukhetha ivalvu
Ukukhethwa kweevalvu ngokubanzi kulandela la manyathelo alandelayo:
1. Misela imeko yokusebenza yevalvu ngokwendlela esetyenziswa ngayo ivalvu kwisixhobo okanye kwipayipi yenkqubo. Umzekelo, indawo yokusebenza, uxinzelelo lokusebenza kunye nobushushu bokusebenza, njl.
2. Misela inqanaba lokusebenza kokutywina kwevalvu ngokwendlela yokusebenza, indawo yokusebenza kunye neemfuno zomsebenzisi.
3. Misela uhlobo lwevalvu kunye nemo yokuqhuba ngokwenjongo yevalvu. Iintlobo ezifanaIvalvu yebhabhathane ezinzileyo, Ivalvu yesango ehleli ngerabha,I-valve yesango ehleli ngerabha, ivalvu yokulinganisela, njl. Indlela yokuqhuba efana ne-worm wheel worm, umbane, umoya, njl.
4. Khetha ngokweeparamitha ezimiselweyo zevalvu. Uxinzelelo oluqhelekileyo kunye nobukhulu obuqhelekileyo bevalvu kufuneka zihambelane nombhobho wenkqubo ofakiweyo. Ivalvu ifakelwe kumbhobho wenkqubo, ngoko ke imeko yayo yokusebenza kufuneka ihambelane nokukhethwa koyilo lombhobho wenkqubo. Emva kokuba uxinzelelo oluqhelekileyo lwenkqubo kunye nombhobho zimiselwe, uxinzelelo oluqhelekileyo lwevalvu, ubungakanani obuqhelekileyo kunye noyilo lwevalvu kunye nemigangatho yokuvelisa inokumiselwa. Ezinye iivalvu zimisela ubungakanani obuqhelekileyo bevalvu ngokwesantya sokuhamba okanye ukukhutshwa kwevalvu ngexesha elilinganisiweyo le-medium.
5. Misela uhlobo loqhagamshelo lomphezulu wesiphelo sevalvu kunye nombhobho ngokweemeko zokusebenza zangempela kunye nobukhulu obuqhelekileyo bevalvu. Ezifana neflange, ukuwelda, i-wafer okanye intambo, njl.
6. Misela ulwakhiwo kunye nohlobo lwevalvu ngokwendawo yokufakela, indawo yokufakela, kunye nobukhulu bevalvu. Njengevalvu yesango elimnyama, isiqu esinyukayoivalvu yesango, ivalvu yebhola esisigxina, njl.
7. Ngokweempawu zendlela ephakathi, uxinzelelo lokusebenza kunye nobushushu bokusebenza, ukukhetha ivalvu ngokuchanekileyo nangokufanelekileyo.
