1. Ivalvuumgaqo wokukhetha:
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, kunye nomjikelo omde. Ke ngoko, ivalvu kufuneka ibe nokuthembeka okuphezulu, ukhuseleko, kungekhona ngenxa yokusilela kwevalvu okubangelwe kukhuseleko olukhulu lwemveliso kunye nengozi yokwenzakala komntu, ukuhlangabezana neemfuno zokusebenza komjikelo omde wesixhobo, imveliso eqhubekayo yomjikelo omde yinzuzo, ukongeza, ukunciphisa okanye ukuphepha ukuvuza okubangelwa yivalvu, ukudala umzi-mveliso ococekileyo, ophucukileyo, ulawulo lwe-HsE (oko kukuthi, impilo, ukhuseleko, okusingqongileyo).
(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.
2. Amanyathelo okukhetha ivalvu:
Khetha iivalvu ngokubanzi landela 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 ezifana nevalvu yokusika, ivalvu yokulawula, ivalvu yokhuseleko, ezinye iivalvu ezikhethekileyo, njl. Imo yokuqhuba efana neworm wheel worm, umbane, umoya ongcolileyo, 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, ikliphu okanye umsonto, njl.
6. Misela ulwakhiwo kunye nohlobo lwevalvu ngokwendawo yokufakela, indawo yokufakela, kunye nobukhulu bevalvu. Ezifana nevalvu yesango le-dark rod, ivalvu ye-angle globe, ivalvu yebhola esisigxina, njl.
7. Ngokweempawu zendlela ephakathi, uxinzelelo lokusebenza kunye nobushushu bokusebenza, kukhetho oluchanekileyo nolufanelekileyo lwegobolondo yevalvu kunye nezixhobo zangaphakathi.
