I-valve yokuhlola i-plug-in eguquguqukayo yokusiza ingcindezi i-DLF08-00

Ivalvu yesango yevalvu yokukhulula isho ivalve yesango evalayo (isango) futhi ihamba iqonde emgqeni omaphakathi wesiteshi. I-valve yesango isetshenziselwa ukunqanyulwa kwepayipi. I-valve yesango iyi-valve yesango esetshenziswa kabanzi. Ngokuvamile isetshenziselwa imishini yokunquma nge-DN≥50 mm. Ngezinye izikhathi, ama-valve esango nawo asetshenziselwa imishini encane yokusika. Amavalvu esango anezinzuzo ezilandelayo: ① Ukuvinjwa okuncane koketshezi. ② Amandla angaphandle adingekayo ukuze uvule futhi uvale i-valve yokusiza esebenza ngokuqondile mancane. (3) isiqondiso sento asinqunyelwe. (4) uma ivuleke ngokuphelele, indawo evalekayo ihuzuka kancane izinto ezisebenzayo kunevalvu enqamuliwe. ⑤ Isibalo silula kakhulu futhi inqubo yokubumba yinhle. Amavalvu esango nawo anokusilela okuthile: ① Ubude obuhlobene nedigri yokuvula bukhulu ngokuqhathaniswa. Isikhala sasendlini esidingekayo ukuze kuhlanganiswe sikhulu uma kuqhathaniswa. ② Ngesikhathi sokuvula nokuvala, kukhona ukungqubuzana phakathi kwezindawo zokuvala, okulula ukubangela ukungqubuzana. ③ Amavalvu esango ngokuvamile anezindawo ezimbili zokuvala, okunzima ukuzenza, ukucutshungulwa, ukugaya kanye nokuzinakekela. Amavalvu esango angahlukaniswa abe: (1) amavalve esango ahambisanayo: izindawo zokuvala zihambisana ne-eksisi eqondile, okungukuthi, izindawo ezimbili zokuvala ziyahambisana. Kumavalvu esango ahambisanayo, isakhiwo esine-thrust wedge sivame kakhulu, okungukuthi, kukhona ama-thrust wedges amabili phakathi kwamasango amabili. Le valve yesango ifaneleka kuma-valve esango ane-diameter encane (DN40-300mm) ku-voltage ephansi. Kukhona futhi ipuleti lasentwasahlobo phakathi kwezinqama ezimbili, futhi isiphethu se-torsion singabangela amandla angaphambi kokuqina, okuzuzisa ukuvalwa kwepuleti levalvu yokukhulula ugesi. (2) I-valve yesango le-Wedge: indawo yokuvala yakha i-engeli ethile ene-eksisi eqondile, okungukuthi, izindawo ezimbili zokuvala zakha i-valve yesango eliwuhlaka. Ama-engeli e-oblique okubuka indawo yokuvala ngokuvamile angu-2 52', 3 30', 5, 8, 10, njll. Ukhiye we-engeli izinga lokushisa lempahla. Ngokuvamile, uma izinga lokushisa liphezulu, i-engeli yokubuka kufanele ibe nkulu ukuze kuncishiswe amathuba okushada lapho izinga lokushisa lishintsha.
