Okokuqala,Yini ama-Check Valves, incazelo ye-valve yokuhlola.

I-valve yokuhlola isho ukuthembela ekugelezeni okuphakathi nendawo futhi i-valve ivuleke ngokuzenzakalelayo futhi ivale, esetshenziselwa ukuvimbela ukugeleza kwe-media emuva kwe-valve,

obeye aziwe njengoindlela eyodwa yokugeleza valve,i-valve engabuyi , kanye ne-valve yokucindezela emuva. I-valve yokuhlola iwuhlobo lwe-valve othomathikhi, umsebenzi wayo oyinhloko ukuvimbela ukubuyela emuva kwe-medium, ukuvimbela ipompo kanye ne-drive motor ukuthi ingahlehli, kanye nokukhishwa kwe-container medium. Amavalvu okuhlola angasetshenziswa futhi ukuphakela imigqa lapho ingcindezi ingase ikhuphuke ukuze idlule ukucindezela kwesistimu.

 

Okwesibili, amaphuzu abalulekile wokwakhiwa nokufakwa kwe-valve yokuhlola:

I-1, indawo yokufaka, ukuphakama, ukungenisa nokuthekelisa isiqondiso kufanele kuhlangabezane nezidingo zokuklama, qaphela isiqondiso sokugeleza okuphakathi kufanele kuhambisane nesiqondiso somcibisholo omakwe umzimba we-valve, uxhumano kufanele luqine futhi luvaleke.

2, i-valve kufanele ihlolwe ngaphambi kokufakwa, i-nameplate ye-valve kufanele ihlangabezane nezindinganiso zamanje kazwelonke. Ukuze i-valve ingcindezi yayo yokusebenza ingaphezu kwe-1.0MPa futhi idlala indima yokusika epayipini elikhulu, ukuqina nokuhlolwa kokusebenza okuqinile kufanele kwenziwe ngaphambi kokufakwa, futhi i-valve efanelekayo ingasetshenziswa. Ukuhlolwa kwamandla, ingcindezi yokuhlola izikhathi eziyi-1.5 ukucindezela okuzisholo, ubude besikhathi abukho ngaphansi kuka-5min, igobolondo le-valve, ukupakisha kufanele kuqeqeshwe ngaphandle kokuvuza. Ngokuhlolwa kokuqina, ingcindezi yokuhlola izikhathi ezingu-1.1 zokucindezela okulinganiselwe.

3. Ungalenzi isisindo se-valve yesheke epayipini. Ama-valve okuhlola amakhulu kufanele asekelwe ngokuzimela ukuze angathinteki ukucindezela okukhiqizwa uhlelo lwepayipi.

Okwesithathu, Iphutha kanye nesixazululo

Ⅰ, Ukuvuza kwangaphakathi

1. Indawo yokubeka uphawu ihlanganiswe nokungcola.

2. Indawo yokuvala yonakaliswa umthelela we-hydraulic.

3. Khipha ukungcola endaweni evalekayo nezihlalo bese uzihlanza ngophalafini.

4. Sebenza kabusha i-disc bese uhlala noma ubeke uphawu.

Ⅱ, Ukuvuza kwangaphandle

Ukuvuza emzimbeni we-valve noxhumo lwebhonethi

1. Amabhawodi okuxhumana awaqinisiwe ngokulinganayo noma amandla okuqinisa ngaphambilini awanele.

2. Indawo yokubeka uphawu ye-Flange yonakalisiwe.

3. I-gasket ifakwe ngendlela engafanele futhi yonakele noma yehluleka ngemva kokusetshenziswa isikhathi eside.

4. Qinisa ngokulinganayo amabhawodi namantongomane axhuma umzimba wevalvu nesembozo sevalvu.

5. Sebenza kabusha futhi ulungise indawo yokubeka uphawu ye-flange.

6. Faka esikhundleni i-gasket futhi uyifake ngendlela efanele.

Ⅲ, Idiski liphukile

Ukucindezela okuphakathi ngaphambi nangemva kwe-valve yokuhlola ishintshashintsha, i-disc ivame ukungqubuzana nesihlalo, futhi i-disc yezinye izinto eziphukayo kulula ukuphuka.

1. Khetha i-ductile material disc.

2. Lungisa inqubo ukuze unciphise noma ugweme ukushintshashintsha kwengcindezi njalo ngaphambi nangemva kwe-valve yokuhlola.
