Ekuqaleni,Yintoni i-Check Valves, inkcazo yevalve yokukhangela.

Ivalve yokujonga ibhekisa ekuthembeni kwindlela ephakathi ngokwayo kwaye ivule ngokuzenzekelayo kwaye ivale idiski yevalve, esetyenziselwa ukuthintela umva kwemidiya yevalve,

kwaziwa njengeIvalve yendlela enye,Ivalve engabuyi , kunye nevalve yoxinzelelo lwangasemva. I-valve yokukhangela luhlobo lwe-valve oluzenzekelayo, umsebenzi walo oyintloko kukuthintela umva we-medium, ukuthintela impompo kunye ne-motor drive ekubuyiseleni umva, kunye nokukhutshwa kwe-container medium. Iivalvu zokutshekisha zingasetyenziselwa ukutyisa imigca apho uxinzelelo lunokwenyuka lugqithise uxinzelelo lwenkqubo.

 

Okwesibini, amanqaku aphambili okwakhiwa kwevalve yokukhangela kunye nofakelo:

I-1, indawo yofakelo, ukuphakama, ukungenisa kunye nokuthunyelwa kwamanye amazwe kufuneka kuhlangabezane neemfuno zokuyila, ingqalelo kwisalathiso sokuhamba okuphakathi kufuneka kuhambelane nesalathiso sotolo oluphawulwe ngumzimba wevalve, uqhagamshelwano kufuneka luqine kwaye luvale.

2, ivalve kufuneka ihlolwe phambi kofakelo, i-nameplate yesivalo kufuneka ihlangabezane nemigangatho yesizwe yangoku. Kwi-valve esebenza ngoxinzelelo olukhulu kune-1.0MPa kwaye idlala indima yokusika kumbhobho oyintloko, amandla kunye novavanyo oluqinileyo kufuneka lwenziwe ngaphambi kokufakwa, kwaye i-valve efanelekayo ingasetyenziswa. Uvavanyo lwamandla, uxinzelelo lovavanyo luyi-1.5 amaxesha oxinzelelo oluncinci, ubude bexesha alikho ngaphantsi kwe-5min, igobolondo yevalve, ukupakisha kufuneka ifaneleke ngaphandle kokuvuza. Uvavanyo lokuxinana, uxinzelelo lovavanyo luyi-1.1 amaxesha oxinzelelo lwegama.

3. Musa ukwenza ukuba ivalve yokukhangela ithwale ubunzima kumbhobho. Iivalve ezinkulu zokuhlola kufuneka zixhaswe ngokuzimeleyo ukuze zingachaphazeleki ngoxinzelelo oluveliswa yinkqubo yombhobho.

Okwesithathu, Impazamo kunye nesisombululo

Ⅰ, Ukuvuza kwangaphakathi

1. Umphezulu wokutywina unamathele ngokungcola.

2. Umphezulu wokutywina wonakaliswe yimpembelelo ye-hydraulic.

3. Susa ukungcola kwidiskhi kunye neendawo zokutywina zezihlalo kwaye uzicoce ngeparafini.

4. Rework disc kunye nesihlalo okanye indawo yesitywina.

Ⅱ, Ukuvuza kwangaphandle

Ukuvuza kumzimba wevalvu kunye noqhagamshelo lwebhonethi

1. Iibholiti zokudibanisa aziqiniswanga ngokulinganayo okanye amandla okuqinisa kwangaphambili akwanelanga.

2. Umphezulu wokutywina we-Flange wonakaliswe.

3. I-gasket ifakwe ngokungafanelekanga kwaye yonakaliswe okanye iyasilela emva kokusetyenziswa kwexesha elide.

4. Gxininisa ngokulinganayo iibholiti kunye namandongomane adibanisa umzimba wevalve kwisivalo sevalvu.

5. Phinda usebenze kwaye ulungise indawo yokutywina yeflange.

6. Faka indawo ye-gasket kwaye uyifake ngokuchanekileyo.

Ⅲ, Idiskhi yophukile

Uxinzelelo oluphakathi ngaphambi nangemva kokuba i-valve yokutshekisha iguquguquka, i-disc idibanisa rhoqo kunye nesihlalo, kwaye i-disc yezinye izinto ezinqabileyo zilula ukuphulwa.

1. Khetha idiski yezinto eziphathekayo.

2. Lungisa inkqubo yokunciphisa okanye ukuphepha ukuguquguquka kwengcinezelo rhoqo ngaphambi nangemva kwevalve yokutshekisha.
