Wafer taki takireree mohiotia ana ano ko nga rewharewharewharewha, nga reera o te tuara, me nga taarua whakamuri.Ko enei momo reera ka whakatuwherahia, ka katihia e te kaha i puta mai i te rere o te reo i roto i te paipa, no tetahi momo takirere aunoa.
Ko te taki taki ko te ti'aturi i runga i te rere o te reo ake, ka whakatuwhera aunoa me te kati i te paera takirere, whakamahia hei aukati i te rerenga rerenga reo, e mohiotia ana ko te taki taki, taki taki, backflow valve, me te back pressure valve.Ko te taki taki no te ahua o te takirere aunoa, ko tana mahi matua ko te aukati i te rerenga o muri o te hunga pāpāho, te aukati i te papu me te peia te hurihanga motuka, tae atu ki te tukunga o te hunga pāpāho.Ka taea hoki te whakamahi i nga takirere kia piki ake te pehanga ki runga ake i te pehanga punaha o te punaha awhina ki te whakarato i te paipa tuku.Ka taea te wehea te takirere taki ki te piu taki takirere (e ai ki te pokapū o te hurihanga kaha) me te taki taki hiki (neke haere i te tuaka).
Tuatahi, ko te whakamahi i te topenga-i runga i te taki taki taki taki i whakauruhia ki roto i te punaha paipa, ko tana mahi nui ko te aukati i te rerenga o te hunga pāpāho, ko te taki taki he momo o te takirere aunoa e whakawhirinaki ana ki te pehanga pāpāho ki te whakatuwhera me te kati.Rawhi taki taki he pai mo te pēhanga ingoa PN1.0MPa ~ 42.0MPa, Class150 ~ 25000, diameter ingoa DN15 ~ 1200mm, NPS1 / 2 ~ 48, pāmahana whakahaere -196 ~ 540 ℃ o nga pipelines ngā, whakamahia ki te ārai i te rerenga o te pāpāho.Na roto i te kowhiringa o nga mea rereke, ka taea te whakamahi ki te wai, ki te mamaoa, ki te hinu, ki te waikawa nitric, ki te waikawa acetic, ki te kaha oxidizing media me te waikawa uric me etahi atu papaaho.
Ko nga mea matua o te wafer taki taki he waro maitai, iti-mahana maitai, duplex maitai (SS2205/SS2507), titanium alloy, konumohe parahi, Inconel, SS304, SS304L, SS316, SS316L, chrome-molybdenum maitai, Monel (400/ 500), 20 # koranu, Hastelloy me etahi atu mea whakarewa.
Tuatoru, ko nga paerewa me nga tikanga o te wafer check valve
Hoahoa: API594, API6D, JB/T89372,
Te roa o te kanohi ki te kanohi: API594, API6D, DIN3202, JB/T89373,
Te pehanga me te pāmahana: ANSI B16.34, DIN2401, GB/T9124, HG20604, HG20625, SH3406, JB/T744,
Paerewa whakamatautau me te tirotiro: API598, JB/T90925
Piping Flanges: JB/T74~90, GB/T9112-9124, HG20592~20635, SH3406, ANSI B 16.5, DIN2543-2548, GB/T13402, 4ASMEB56.
Tuawha, ko nga ahuatanga o te hanganga o te paera taki whakawiri
1.Short hanganga roa, tona roa hanganga ko anake 1/4~1/8 o te piu tuku iho flange taki takirere.
2. rōrahi iti, te taimaha marama, tona taimaha ko anake te takirere taki takirere tuku iho 1/4 ~ 1/2
3. Ka tere te kati o te papa takirere, he iti te pehanga hama wai
4. Ka taea te whakamahi paipa whakapae, poutū ranei, ngawari ki te whakauru
5. Te ara rere maeneene, he iti te parenga wai
Mahi 6.Sensitive, mahi hiri pai
7.He poto te whiu kopae, he iti te paanga kati
8.Ko te hanganga katoa he maamaa me te taapiri, he ataahua te ahua
9. Te roa o te ratonga me te mahi pono
rima.Ko te mahi hiri o te wafer check valve Ka taea e te wafer check valve ngawari te whakatutuki i te kore o te rerenga, engari ko te wafer check valve pakeke ehara i te valve kore-leakage.He reiti rerenga ke.E ai ki te paerewa tirotiro o API598, mo te taki taki me te nohoanga whakarewa, mo te rahi o te DN100, ko te reiti rerenga wai mo ia meneti he 12CC.
