Iji rụọ ọrụ nke ọma ịgbatị ndụ ọrụ nkePVC bọl valves, ọ dị mkpa ijikọta ọrụ ahaziri ahazi, na-arụ ọrụ mgbe niile, na usoro nlekọta ezubere iche. Ụzọ ndị a kapịrị ọnụ bụ ndị a:
Nrụnye na arụ ọrụ ahaziri ahazi
1. Nwụnye chọrọ
(a) Ntuziaka na ọnọdụ: Na-ese n'elu mmiribọọlụ valvụmkpa ka etinyere ya n'ahịrị iji dobe axis nke ọkwa bọọlụ ma kwalite arụmọrụ akara site na iji ibu nke aka ha; A ga-etinyerịrị valvụ bọọlụ pụrụ iche (dị ka ndị nwere ngwaọrụ mgbochi ịgbasa) nke ọma dịka usoro mgbaba nke usoro ahụ si dị.
(b) Nhicha pipeline: Wepụ nke ọma welding slag na adịghị ọcha n'ime pipeline tupu echichi ya ka ịzenarị imebi oghere ma ọ bụ akara elu.
(c) Usoro njikọ: Njikọ Flange na-achọ njigide nke bolts n'otu n'otu na torque ọkọlọtọ; Were usoro jụrụ oyi iji chebe akụkụ ndị dị n'ime valvụ mgbe ị na-agbado ọkụ.
2. Ụkpụrụ ọrụ
(a) Njikwa Torque: Zere oke ike n'oge arụ ọrụ ntuziaka, na draịva eletrik / pneumatic kwesịrị dakọtara na torque imewe.
(b) Ngbanwe ọsọ: Jiri nwayọọ meghee ma mechie valvụ iji gbochie mmetụta hammer mmiri imebi pipeline ma ọ bụ ihe mkpuchi.
(c) Arụ ọrụ mgbe niile: Valves ndị na-arụ ọrụ ogologo oge kwesịrị imeghe ma mechie kwa ọnwa 3 ọ bụla iji gbochie eriri valve na-arapara na oche valve.
Ndozi na nlekọta usoro
1. Nchacha na nyocha
(a) Na-asachapụ uzuzu dị n'elu na ntụpọ mmanụ nke valvụ kwa ọnwa, na-eji ihe nhicha na-anọpụ iche iji zere mmebi nke ihe PVC.
(b) Lelee iguzosi ike n'ezi ihe nke elu akara wee nyochaa ngwa ngwa ọ bụla leaks (dị ka mgbanaka akara ịka nká ma ọ bụ ihe mgbochi ihe si mba ọzọ).
2. Njikwa mmanu mmanu
(a) Na-agbakwunye griiz PVC dakọtara mgbe niile (dị ka griiz silicone) na valvụ stem nut iji belata nguzogide esemokwu.
(b) A na-edozi oge mmanu mmanu dịka mpaghara eji eme ihe: otu ugboro kwa ọnwa 2 na gburugburu iru mmiri na otu ugboro n'akụkụ anọ ọ bụla na gburugburu nkụ.
3. Nlekọta akara
(a) Dochie ihe mgbanaka EPDM/FPM mgbe niile (a na-atụ aro kwa afọ 2-3 ma ọ bụ dabere na akwa na akwa).
(b) Hichaa oghere oche valvụ mgbe a na-ekesa iji hụ na etinyere mgbanaka akara ọhụrụ na-enweghị mgbagha.
Mgbochi na njikwa mmejọ
1. nchara na mgbochi corrosion
(a) Mgbe nchara nchara, jiri mmanya mmanya ma ọ bụ ihe na-atọpụ ihe wepụ ya n'ọnọdụ dị nro; Ọrịa siri ike chọrọ nnọchi valve.
(b) Tinye mkpuchi mkpuchi ma ọ bụ tinye agba mgbochi nchara na gburugburu ebe ndị na-emebi emebi.
2. Ijikwa kaadị ndị rapaara
Maka ntakịrị mkpakọ, gbalịa na-eji mgbanaka iji nyere aka n'ịtụgharị valvụ ahụ;
Mgbe ị rapaara nke ukwuu, jiri ikuku ikuku na-ekpo ọkụ na-ekpo ọkụ na mpaghara valvụ ahụ (≤ 60 ℃), ma jiri ụkpụrụ nke mgbasawanye ọkụ na nkwekọrịta na-atọpụ valvụ isi.
