Ukufakwa kwamavalvu esango, amavalvu embulunga kanye namavalvu okuhlola

I-valve yesango, eyaziwa nangokuthi i-gate valve, iyi-valve esebenzisa isango ukulawula ukuvulwa nokuvalwa. Ilungisa ukuhamba kwephayiphi futhi ivula futhi ivale amaphayiphi ngokushintsha ingxenye yephayiphi. Ama-gate valve asetshenziswa kakhulu kumaphayiphi ane-media yoketshezi evulekile ngokuphelele noma evaliwe ngokuphelele. Ngokuvamile asikho isidingo sokuqondiswa kokufakwa kwe-gate valve, kodwa ayikwazi ukufakwa ibheke phansi.

Aivalvu yomhlabaiyivalvu esebenzisa idiski yevalvu ukulawula ukuvulwa nokuvalwa. Ngokushintsha isikhala phakathi kwediski yevalvu nesihlalo sevalvu, okungukuthi, ukushintsha usayizi wesigaba esiphambene nesiteshi, ukugeleza okuphakathi noma isiteshi esiphakathi kuyanqanyulwa. Lapho ufaka ivalvu yokumisa, kufanele unake indlela yokugeleza koketshezi.
Isimiso okumele silandelwe lapho kufakwa ivalvu yokumisa ukuthi uketshezi olusepayipini ludlule emgodini wevalvu kusukela phansi kuya phezulu, okwaziwa ngokuthi “ukungena okuphansi nokuphezulu”, futhi ukufakwa okuphambene akuvunyelwe.

I-valve yokuhlola, eyaziwa nangokuthi i-check valve kanye ne-one-way valve, iyi-valve evuleka futhi ivale ngokuzenzakalelayo ngaphansi komehluko wokucindezela phakathi kwangaphambili nangemuva kwe-valve. Umsebenzi wayo ukuvumela i-medium ukuthi igeleze ohlangothini olulodwa kuphela futhi ivimbele i-medium ukuthi igeleze emuva ohlangothini oluphambene. Ngokwezakhiwo ezahlukene, ama-check valve afaka ama-lift, ama-swing kanye nama-butterfly clamp check valve. Ama-lift check valve ahlukaniswe ngezinhlobo ezivundlile neziqondile. Uma ufaka i-check valve, kufanele futhi unake indlela yokugeleza kwe-medium futhi ungayifaki emuva.

Ukufakwa kwevalvu yokunciphisa umfutho

Ivalvu yokunciphisa ingcindezi iyivalvu enciphisa ingcindezi yokungena iye ekucindezelweni kokuphuma okudingekayo ngokulungiswa futhi igcina ngokuzenzakalelayo ingcindezi yokukhipha ezinzile ngokuthembela emandleni e-medium uqobo.

Ngokombono we-fluid mechanics, i-valve yokunciphisa ingcindezi iyinto evimbela ukugoba engashintsha ukumelana kwendawo. Okusho ukuthi, ngokushintsha indawo evimbela ukugoba, izinga lokugeleza kanye namandla e-kinetic oketshezi kuyashintshwa, ngaleyo ndlela kukhiqizwe ukulahlekelwa okuhlukile kwengcindezi, ngaleyo ndlela kufezwe injongo yokunciphisa ingcindezi. Ngemuva kwalokho, kuncike ekulungisweni kohlelo lokulawula nokulawula, amandla entwasahlobo asetshenziswa ukulinganisela ukuguquguquka kwengcindezi ngemuva kwe-valve, ukuze ingcindezi ngemuva kwe-valve ihlale ingaguquki ngaphakathi kobubanzi obuthile bephutha.

Ukufakwa kwevalvu yokunciphisa umfutho

1. Iqembu lamavalvu okunciphisa ingcindezi elifakwe ngokuqondile livame ukufakwa odongeni endaweni ephakeme efanele ukusuka phansi; iqembu lamavalvu okunciphisa ingcindezi elifakwe ngokuqondile livame ukufakwa epulatifomu yokusebenza ehlala njalo.

2. Sebenzisa insimbi ebunjiwe ukufaka odongeni ngaphandle kwamavalvu amabili okulawula (avame ukusetshenziswa kumavalvu okumisa) ukuze wakhe i-bracket. Ipayipi elidlulayo nalo linamathele ku-bracket futhi lilinganiswe.

3. Ivalvu yokunciphisa ingcindezi kufanele ifakwe iqonde phezulu epayipini elivundlile futhi akumelwe ithambeke. Umcibisholo emzimbeni wevalvu kufanele ukhombe indlela yokugeleza okuphakathi futhi awukwazi ukufakwa ubheke emuva.

4. Ama-valve okumisa kanye nama-gauge okucindezela okuphezulu nokuphansi kufanele afakwe kuzo zombili izinhlangothi ukuze kubonwe izinguquko zokucindezela ngaphambi nangemva kwe-valve. Ububanzi bepayipi ngemuva kwe-valve yokunciphisa ukucindezela kufanele bube bukhulu ngama-2#-3# kunobubanzi bepayipi lokungena eliphambi kwe-valve, futhi kufanele kufakwe ipayipi elidlulayo ukuze kube lula ukugcinwa.

5. Ipayipi elilinganisa ingcindezi yevalvu yokunciphisa ingcindezi ye-diaphragm kufanele ixhunywe epayipini elinomfutho ophansi. Amapayipi anomfutho ophansi kufanele afakwe amavalvu okuphepha ukuqinisekisa ukusebenza okuphephile kwesistimu.

6. Uma isetshenziselwa ukuqeda ukucindezeleka ngomusi, kufanele kufakwe ipayipi lokukhipha amanzi. Ezinhlelweni zamapayipi ezinezidingo zokuhlanza eziphakeme, kufanele kufakwe isihlungi phambi kwevalvu yokunciphisa umfutho.

7. Ngemva kokufakwa kweqembu levalvu yokunciphisa ingcindezi, ivalvu yokunciphisa ingcindezi kanye nevalvu yokuphepha kufanele kuhlolwe ingcindezi, kuhlanzwe futhi kulungiswe ngokwezidingo zomklamo, futhi ukulungiswa kufanele kumakwe.

8. Uma uhlanza ivalvu yokunciphisa ingcindezi, vala ivalvu yokungena yokunciphisa ingcindezi bese uvula ivalvu yokuhlanza ukuze uhlanze.

Ukufakwa kwesicupho

Umsebenzi oyisisekelo wesicupho somusi ukukhipha amanzi ahlanganisiwe, umoya kanye negesi yekhabhoni dioksijini ohlelweni lomusi ngokushesha okukhulu; ngesikhathi esifanayo, kungavimbela ngokuzenzakalelayo ukuvuza komusi ngezinga elikhulu. Kunezinhlobo eziningi zezicupho, ngasinye sinamakhono ahlukene.

Ngokwezimiso ezahlukene zokusebenza kwezicupho zomusi, zingahlukaniswa ngezinhlobo ezintathu ezilandelayo:

Okwemishini: Isebenza ngokwezinguquko ezingeni le-condensate ku-trap, okuhlanganisa:

Uhlobo lokuntanta: Intanta iyindilinga engenalutho evaliwe.

Uhlobo lokuntanta oluvuleka phezulu: Intanta imise okwebhakede futhi ivuleka phezulu.

Uhlobo lokuntanta oluvula phansi: Intanta inomumo ofana nomgqomo kanti intanta ivulwa phansi.

Uhlobo lwe-thermostatic: lusebenza ngokwezinguquko ekushiseni koketshezi, okuhlanganisa:

Ishidi le-bimetallic: Isici esibucayi yishidi le-bimetallic.

Uhlobo lokucindezela komhwamuko: Isici esibucayi siyi-bellows noma i-cartridge, egcwele uketshezi oluguquguqukayo.

Uhlobo lwe-Thermodynamic: Lusebenza ngokusekelwe ezinguqukweni ze-thermodynamic zoketshezi.

Uhlobo lwediski: Ngenxa yamazinga okugeleza ahlukene koketshezi negesi ngaphansi kwengcindezi efanayo, kukhiqizwa ukucindezela okuhlukile okuguquguqukayo nokungaguquki ukuze kuqhutshwe ivalvu yediski ukuthi ihambe.

Uhlobo lokushaya kwenhliziyo: Lapho ukuqina kwamazinga okushisa ahlukene kudlula kuma-throttle orifice plates ochungechunge lwezingodo ezimbili, kwakheka ukucindezela okuhlukene phakathi kwezingodo ezimbili zama-throttle orifice plates, okuqhuba i-valve disc ukuthi inyakaze.

Ukufakwa kwesicupho

1. Amavalvu okumisa (amavalvu okumisa) kufanele afakwe ngaphambili nangemuva, futhi kufanele kufakwe isihlungi phakathi kwesicupho kanye nevalvu yokumisa yangaphambili ukuze kuvinjelwe ukungcola emanzini anomswakama ukuthi kungavimbi isicupho.

2. Kufanele kufakwe ipayipi lokuhlola phakathi kwesicupho kanye nevalvu yokuma yangemuva ukuze kuhlolwe ukuthi isicupho sisebenza kahle yini. Uma kuphuma umusi omningi lapho uvula ipayipi lokuhlola, isicupho sonakele futhi sidinga ukulungiswa.

3. Inhloso yokusetha ipayipi elidlulayo ukukhipha inani elikhulu lamanzi ahlanganisiwe ngesikhathi sokuqalisa nokunciphisa umthwalo wokukhipha amanzi wesicupho.

4. Uma ivalvu yokukhipha amanzi isetshenziswa ukususa i-condensate emishinini yokushisa, kufanele ifakwe engxenyeni engezansi yemishini yokushisa ukuze ipayipi lamanzi eli-condensate libuyele phezulu kuvalvu yokukhipha amanzi ukuze kuvinjelwe ukunqwabelana kwamanzi emishinini yokushisa.

5. Indawo yokufaka kufanele ibe seduze nendawo yokukhipha amanzi ngangokunokwenzeka. Uma ibanga lide kakhulu, umoya noma umusi unganqwabelana epayipini elide nelincane eliphambi kwesicupho.

6. Uma ipayipi eliyinhloko elivundlile elinomusi lide kakhulu, kufanele kucatshangelwe izinkinga zokukhipha amanzi.
