A.Ukufakwa kwevalvu yesango
Ivalvu yesango, eyaziwa ngokuba yi-gate valve, yi-valve esebenzisa i-gate ukulawula ukuvulwa nokuvalwa, kwaye ilungisa ukuhamba kombhobho kwaye ivule kwaye ivale umbhobho ngokutshintsha icandelo elinqamlezileyo.Iivalvu zesango Zisetyenziswa kakhulu kwiipayipi ezivula okanye ezivala ngokupheleleyo i-fluid medium. Ukufakelwa kweevalvu zesango ngokubanzi akunazo iimfuno zecala, kodwa akunakujikwa.
B.Ukufakelwa kweiglobhu ivalvu
Ivalvu yeglobe yivalvu esebenzisa idiski yevalvu ukulawula ukuvulwa nokuvalwa. Lungisa ukuhamba okuphakathi okanye unqumle indlela ephakathi ngokutshintsha umsantsa phakathi kwediski yevalvu kunye nesihlalo sevalvu, oko kukuthi, ukutshintsha ubungakanani becandelo letshaneli. Xa ufaka ivalvu yokuvala, kufuneka kuqwalaselwe indlela yokuhamba kolwelo.
Umgaqo ekufuneka ulandelwe xa kufakwa ivalvu yeglobe kukuba ulwelo olukwipayipi ludlule kumngxuma wevalvu ukusuka ezantsi ukuya phezulu, owaziwa ngokuba yi-"low in and high out", kwaye akuvumelekanga ukuyifaka ngasemva.
C.Ukufakelwa kwevalvu yokujonga
Ivalvu yokujonga, eyaziwa ngokuba yi-check valve kunye ne-one-way valve, yi-valve evuleka kwaye ivale ngokuzenzekelayo phantsi kwesenzo somahluko woxinzelelo phakathi komphambili nomva we-valve. Umsebenzi wayo kukwenza i-medium flow kwicala elinye kuphela kwaye ithintele i-medium ukuba ibuyele kwicala elingasemva. Ngokwezakhiwo zayo ezahlukeneyo,iivalvu zokujonga ziquka uhlobo lokulindisa, uhlobo lokujika kunye nohlobo lwe-butterfly wafer. Ivalvu yokujonga ukulindisa yahlulwe yaba tye kunye nethe nkqo. Xa ufakaivalvu yokujonga, kufuneka kuqwalaselwe nendlela esebenza ngayo le medium kwaye ayinakufakelwa ngasemva.
D.Ukufakelwa kwevalvu yokunciphisa uxinzelelo
Ivalvu yokunciphisa uxinzelelo yivalvu enciphisa uxinzelelo lokungena ukuya kuxinzelelo oluthile olufunekayo lokukhupha ngokulungelelanisa, kwaye ixhomekeke kumandla esixhobo ngokwaso ukugcina ngokuzenzekelayo uxinzelelo lokukhupha luzinzile.
1. Iqela levalvu yokunciphisa uxinzelelo elifakwe ngokuthe nkqo lihlala libekwe eludongeni kubude obufanelekileyo ukusuka emhlabeni; iqela levalvu yokunciphisa uxinzelelo elifakwe ngokuthe nkqo lihlala lifakwe kwiqonga lokusebenza elisisigxina.
2. Intsimbi esetyenziswayo ifakwa eludongeni ngaphandle kweevalvu ezimbini zolawulo (ezidla ngokusetyenziselwa iivalvu zeglobe) ukuze zenze ibracket, kwaye umbhobho we-bypass nawo unamathele kwibracket ukuze ulingane kwaye ulungelelaniswe.
3. Ivalvu yokunciphisa uxinzelelo kufuneka ifakwe ime nkqo kumbhobho othe tye, kwaye akufuneki ithambeke. Utolo olusemzimbeni wevalvu kufuneka lukhombe kwicala lokuhamba okuphakathi, kwaye akufuneki lufakwe ngasemva.
4. Iivalvu zeglobe kunye neegeyiji zoxinzelelo oluphezulu noluphantsi kufuneka zifakwe kumacala omabini ukuze kubonwe utshintsho loxinzelelo ngaphambi nasemva kwevalvu. Ububanzi bombhobho ongasemva kwevalvu yokunciphisa uxinzelelo kufuneka bube bukhulu nge-2#-3# kunobubanzi bombhobho wokungena ngaphambi kwevalvu, kwaye kufuneka kufakwe umbhobho we-bypass ukuze kugcinwe ucoceko.
5. Umbhobho olinganisa uxinzelelo wevalvu yokunciphisa uxinzelelo lwe-membrane kufuneka uqhagamshelwe kumbhobho woxinzelelo oluphantsi. Imibhobho yoxinzelelo oluphantsi kufuneka ixhotyiswe ngeevalvu zokhuseleko ukuqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo.
6. Xa isetyenziselwa ukuthomalalisa umphunga, kufuneka kubekwe umbhobho wokukhupha amanzi. Kwiinkqubo zemibhobho ezifuna ukucocwa okuphezulu, kufuneka kufakwe isihluzo phambi kwevalvu yokunciphisa uxinzelelo.
7. Emva kokuba iqela levalvu yokunciphisa uxinzelelo lifakiwe, ivalvu yokunciphisa uxinzelelo kunye nevalvu yokhuseleko kufuneka ivavanywe uxinzelelo, ihlanjwe kwaye ilungiswe ngokweemfuno zoyilo, kwaye kufuneka kwenziwe uphawu olulungisiweyo.
8. Xa uhlamba ivalvu yokunciphisa uxinzelelo, vala ivalvu yokungena yesinciphisi soxinzelelo uze uvule ivalvu yokucoca ukuze uhlambe.
E.Ukufakwa kwee-traps
Umsebenzi osisiseko wesithintelo somphunga kukukhupha amanzi aqunqiweyo, umoya kunye negesi yekhabhoni-dayoksayidi kwinkqubo yomphunga ngokukhawuleza; kwangaxeshanye, inokuthintela ngokuzenzekelayo ukuvuza komphunga kakhulu. Kukho iintlobo ezininzi zezithintelo, nganye inemisebenzi eyahlukileyo.
1. Iivalvu zokuvala (iivalvu zokuvala) mazibekwe ngaphambi nasemva, kwaye kufuneka kubekwe isihluzo phakathi komgibe kunye nevalvu yokuvala engaphambili ukuthintela ukungcola emanzini axineneyo ukuba kungavimbi umgibe.
2. Kufuneka kufakwe umbhobho wokuhlola phakathi komgibe womphunga kunye nevalvu yokuvala engasemva ukujonga ukuba umgibe womphunga usebenza ngokwesiqhelo na. Ukuba umphunga omninzi uphuma xa umbhobho wokuhlola uvulwa, oko kuthetha ukuba umgibe womphunga uphukile kwaye kufuneka ulungiswe.
3. Injongo yokuseta umbhobho odlulayo kukukhupha amanzi amaninzi aqunyiweyo ngexesha lokuqalisa kunye nokunciphisa umthwalo wokukhupha amanzi kumgibe.
4. Xa umgibe usetyenziselwa ukuthulula amanzi aqunyiweyo esixhobo sokufudumeza, kufuneka ufakwe kwicandelo elisezantsi lesixhobo sokufudumeza, ukuze umbhobho wokufunxa ubuyiselwe ngokuthe nkqo kumgibe womphunga ukuthintela amanzi ukuba angagcinwa kwisixhobo sokufudumeza.
5. Indawo yokufakela kufuneka ibe kufutshane nendawo yokukhupha amanzi. Ukuba umgama ukude kakhulu, umoya okanye umphunga uya kuqokelelana kumbhobho omncinci ophambi komgibe.
6. Xa umbhobho othe tye wombhobho oyintloko womphunga umde kakhulu, ingxaki yokukhupha amanzi kufuneka iqwalaselwe.
F.Ukufakwa kwevalvu yokhuseleko
Ivalvu yokhuseleko yivalvu ekhethekileyo apho iindawo zokuvula nezokuvala zihlala zivaliwe phantsi kwesenzo samandla angaphandle. Xa uxinzelelo lwesixhobo kwisixhobo okanye kumbhobho lunyuka ngaphaya kwexabiso elichaziweyo, lukhupha isixhobo ngaphandle kwenkqubo ukuthintela uxinzelelo oluphakathi kumbhobho okanye kwisixhobo ukuba lungadluli kwixabiso elichaziweyo.
1. Ngaphambi kokufakwa, imveliso kufuneka ihlolwe ngononophelo ukuqinisekisa ukuba kukho isatifiketi sokuhambelana nemigaqo kunye nencwadi yemiyalelo yemveliso, ukuze kucaciswe uxinzelelo oluqhubekayo xa uphuma efektri.
2. Ivalvu yokhuseleko kufuneka ibekwe kufutshane kangangoko neqonga ukuze ihlolwe kwaye igcinwe.
3. Ivalvu yokhuseleko kufuneka ifakwe ngokuthe nkqo, i-medium mayiphume ukusuka ezantsi ukuya phezulu, kwaye i-vertical stem yevalvu mayijongwe.
4. Kwiimeko eziqhelekileyo, iivalvu zokuvala azinakubekwa ngaphambi nasemva kwevalvu yokhuseleko ukuqinisekisa ukhuseleko nokuthembeka.
5. Ukunciphisa uxinzelelo lwevalvu yokhuseleko: xa i-medium ingulwelo, idla ngokukhutshwa iye kwipayipi okanye kwinkqubo evaliweyo; xa i-medium iyigesi, idla ngokukhutshwa iye emoyeni ongaphandle;
6. Isixhobo seoyile negesi ngokubanzi sinokukhutshelwa emoyeni, kwaye indawo yokuphuma kwevalvu yokhuseleko kufuneka ibe phezulu nge-3m kunezakhiwo ezijikelezileyo eziphezulu, kodwa le miqathango ilandelayo kufuneka ikhutshelwe kwinkqubo evaliweyo ukuqinisekisa ukhuseleko.
7. Ububanzi bombhobho wabantu kufuneka bulingane ubuncinane nobubanzi bombhobho wokungena wevalvu; ububanzi bombhobho wokukhupha amanzi akufuneki bube mncinci kunobubanzi bokuphuma kwevalvu, kwaye umbhobho wokukhupha amanzi kufuneka ukhokelwe ngaphandle kwaye ufakwe ngengqiniba, ukuze umbhobho wokukhupha amanzi ujonge kwindawo ekhuselekileyo.
8. Xa ivalvu yokhuseleko ifakiwe, xa unxibelelwano phakathi kwevalvu yokhuseleko kunye nezixhobo kunye nombhobho luvula i-welding, ububanzi bokuvula kufuneka bufane nobubanzi obuqhelekileyo bevalvu yokhuseleko.
