A.Ukufakwa kwevalvu yesango
Ivalvu yesango, eyaziwa nangokuthi yi-gate valve, yi-valve esebenzisa isango ukulawula ukuvulwa nokuvalwa, begodu ilungisa ukugeleza kwepayipi bese ivula begodu ivale iphayiphi ngokutjhugulula isigaba esiphambanweni.Amavalvu wesango zisetjenziselwa khulu amapayipi avula ngokuzeleko nofana avala ngokuzeleko umkhakha we-fluid. Ukufakwa kwevalvu yesango ngokuvamileko akunazidingo zokuqondisa, kodwana angeze yaphendulwa.
B.Ukufakwa kweiphasi loke ivalvu
I-globe valve yi-valve esebenzisa idiski ye-valve ukulawula ukuvulwa nokuvalwa. Lungisa ukugeleza okuphakathi nofana usike indlela ephakathi ngokutjhugulula isikhala hlangana nediski yevalvu nesihlalo sevalvu, okutjho bona, ukutjhugulula ubukhulu besigaba setjhaneli. Lokha nakufakwa ivalvu yokuvala, kufanele kutjhejwe indlela amanzi ageleza ngayo.
Umthetho okufuze ulandelelwe lokha nakufakwa ivalvu ye-globe kukuthi amanzi asephayiphini adlule emgodini wevalvu ukusuka phasi ukuya phezulu, okwaziwa ngokuthi "phasi ngaphakathi naphezulu", begodu akukavunyelwa ukuyifakwa emuva.
C.Ukufakwa kwevalvu yokuhlola
Hlola ivalvu, eyaziwa nangokuthi yi-check valve kanye ne-one-way valve, yi-valve evuleka begodu ivale ngokuzenzakalelako ngaphasi kwesenzo somehluko womfutho hlangana ne-valve yangaphambili neyangemuva. Umsebenzi wayo kukwenza bona umkhathi ugeleze ngendlela yinye kwaphela begodu uvimbele umtjhini bona ungabuyeli emuva ngendlela ehlukileko. Ngokuya ngezakhiwo zabo ezihlukileko,amavalvu wokuhlola faka umhlobo wokuphakamisela, umhlobo wokujinga kanye nomhlobo we-butterfly wafer. Lift check valve ihlukaniswe evundlile kanye thwi. Lokha nawufaka iivalvu yokuhlola, kufanele kutjhejwe nendlela yokugeleza kwe-medium begodu angeze yafakwa ngokubuyela emuva.
D.Ukufakwa kwevalvu yokwehlisa umfutho
Ivalvu yokwehlisa umfutho yivalvu eyehlisa umfutho wokungena ukuya emfuthweni othileko otlhogekako wokuphuma ngokulungiswa, begodu ithembele emandleni womtjhini ngokwawo ukugcina umfutho wokuphuma uzinzile.
1. Isiqhema sevalvu yokunciphisa umfutho esifakwe ngokujameleko sivamise ukubekwa eceleni kweboda ngokuphakama okufaneleko ukusuka phasi; isiqhema sevalvu yokwehlisa umfutho esifakwe ngokuvundlileko sivamise ukufakwa endaweni yokusebenza unomphela.
.
3. Ivalvu yokwehlisa umfutho kufanele ifakwe iqondile ephayiphini evundlileko, begodu akukafaneli bona itjhinge. Umcibisholo emzimbeni wevalvu kufanele ukhombe lapho ukugeleza okuphakathi khona, begodu akukafaneli ufakwe emuva.
4. Amavalvu we-globe kanye namageyiji womfutho ophakemeko nophasi kufanele afakwe emahlangothini womabili ukutjheja amatjhuguluko womfutho ngaphambi nangemva kwevalvu. Ububanzi bephayiphi ngemva kwevalvu yokwehlisa umfutho kufanele bube bukhulu nge-2#-3# ukudlula ububanzi bephayiphu yokungena ngaphambi kwevalvu, begodu kufanele kufakwe ipayipi lokudlula ukulungiswa.
5. Iphayiphu yokulinganisa umfutho wevalvu yokwehlisa umfutho we-membrane kufanele ixhunywe kuphayiphi yomfutho ophansi. Amapayipi anomfutho ophasi kufanele afakwe amavalvu wokuphepha ukuqinisekisa ukusebenza okuphephileko kwehlelo.
6. Lokha nayisetjenziselwa ukuqeda umtjhiso, kufanele kubekwe ipayipi lokukhipha amanzi. Eenhlelweni zamapayipi ezitlhoga izinga eliphezulu lokuhlanzwa, kufanele kufakwe isefo ngaphambi kwevalvu yokwehlisa umfutho.
.
8. Lokha nawuhlanza ivalvu yokwehlisa umfutho, vala ivalvu yokungena ye-pressure reducer bese uvula ivalvu yokuhlanza ukuhlanza.
E.Ukufakwa kweenthiyo
Umsebenzi oyisisekelo wesithiyo somtjhiso kukukhupha amanzi ahlanganisiweko, umoya kanye nerhasi yekhabhoni-dayokisayidi erherhweni lomtjhiso msinyana; ngesikhathi esifanako, ingavimbela ngokuzenzakalelako ukuvuza komtjhiso ngezinga elikhulu. Kuneentlobo ezinengi zezithiyo, enye nenye inokusebenza okuhlukileko.
.
2. Kufanele kufakwe ipayipi lokuhlola hlangana nesithiyo somtjhiso kanye nevalvu yokuvala yangemuva ukuhlola bona isithiyo somtjhiso sisebenza kuhle na. Nangabe kukhutjhwa umtjhiso omnengi lokha nakuvulwa ipayipi lokuhlola, kutjho bona isithiyo somtjhiso siphukile begodu kufuze silungiswe.
3. Umnqopho wokubeka ipayipi lokudlula kukhipha inani elikhulu lamanzi ahlanganisiweko ngesikhathi sokuthoma begodu kwehlise umthwalo wokukhipha amanzi womgibe.
.
5. Indawo yokufaka kufanele ibe seduze nendawo yokukhipha amanzi. Nangabe ibanga likude khulu, umoya nofana umtjhiso uzokubuthelela epayipini elincani phambi kwesithiyo.
6. Lokha iphayiphi evundlileko yepayipi elikhulu lomtjhiso lide khulu, umraro wokukhipha amanzi kufanele uqalwe.
F.Ukufakwa kwevalvu yokuphepha
Ivalvu yokuphepha yivalvu ekhethekileko yokuthi iingcenye ezivulako nezivalako zisebujameni obujayelekileko bokuvala ngaphasi kwesenzo samandla wangaphandle. Lokha umfutho we-medium ngaphakathi kwemitjhini nofana ephayiphini ukhuphuka ngaphezu kwenani elibekiweko, ukhipha umphakathi ngaphandle kwehlelo ukukhandela umfutho we-medium ngaphakathi kwepayipi nofana imisebenzi bona ungadluli inani elibekiweko. .
1. Ngaphambi kokufakwa, umkhiqizo kufanele uhlolwe ngokutjheja ukuqinisekisa bona ingabe kunesitifiketi sokuvumelana kanye nebhukwana lomkhiqizo, ukwenzela bona kucaciswe umfutho ongaguqukiko lokha nawuphuma efemini.
2. Ivalvu yokuphepha kufanele ihlelwe eduze nepulatifomu ukuze ihlolwe begodu ilungiswe.
3. Ivalvu yokuphepha kufanele ifakwe ithe nkqo, umkhathi kufanele ugeleze ukusuka phasi ukuya phezulu, begodu ukuma kwesiqu sevalvu kufanele kuhlolwe.
4. Ngaphasi kobujamo obujayelekileko, amavalvu wokuvala angeze abekwa ngaphambi nangemva kwevalvu yokuphepha ukuqinisekisa ukuphepha nokuthembeka.
. lokha umkhakha uyigesi, uvamise ukukhishwa emmoyeni wangaphandle;
.
7. Ububanzi bepayipi labantu kufanele bulingane okungenani nobubanzi bepayipi lokungena levalvu; ububanzi bephayiphu yokukhipha akukafaneli bube buncani kunobubanzi bokuphuma kwevalvu, begodu ipayipi lokukhipha kufanele lidoselwe ngaphandle bese lifakwa ngendololwane, ukwenzela bona indawo yokuphuma yepayipi iqalene nendawo ephephileko.
