CPVC Pūrererere Rere Momo Lever
Nga waahanga hua
1, Ko te hoahoa hanganga rerekee rua, ko te oranga o te ratonga he 5 nga wa o te rererererererere noa
2, Te taipana whakawhiti iti.
Ko nga waahanga ka taea te whakakapi kiato me te ohaoha
Ko te rauemi he nano-whakarereke hei whakapai ake i te pehanga
ātete me te ātete pānga o te hua
5, Matotoru tinana takirere mo te ātete kōpeketanga tiketike
6, 100% te whakamatautau pehanga i mua i te tuku
7, Ko nga waahanga o te tinana me te hiri he mea rongoa mo te pai ake.
Ko te valve butterfly eccentric he mana whakahaere noa, e tohuhia ana e te hoahoa whaanui mo te hanganga rereke, i roto i te whakatuwheratanga me te kati ka taea te whakapai ake i te hiri o te valve me te awhina o te hoahoa rereke. E tohu ana te rewharewha whaanui me te pokapu ki te anga o te whao mo te tuaka hangarite.
Ki te whakatauritea ki nga rere rererererangi whanui, ka tohuhia nga rere rererererangi rereke e te hanganga uaua ake me te utu hangahanga teitei ake. Heoi, i roto i nga mahi whaihua, he pai ake ano te mahi whakahaere me te mahi hiri, ina koa i roto i te pehanga teitei, te teitei-te wera, te kaha-nui me etahi atu purongo matatini, he mea nui ake te mahi o te rewharewha o te rewharewha, kia tika ake ai te whakahaere rere me te pehanga. whakaritenga.
He aha te painga o te takirere rererererere rereke?
1.small rere ātete:
no te mea kua hangaia te porowhita o te riu rererere rereke kia rereke mai i te nohoanga i tetahi tawhiti, ka rere te reo i roto i te takirere, he poto ake te huarahi rere atu i era atu marere, na reira ka iti ake te aukati;
2.Te hiiri pono:
I te wa o te katinga o te puera rererererangi rereke, ka nui ake te pehanga kumete i waenga i te spool me te nohoanga, ka pai ake te hiri; i te wa e whakatuwhera ana, ka whakawhirinaki te nuinga ki te waku i waenga i te spool me te nohoanga hei whakarite i te hiri.
3.Te mate pehanga iti:
Ka taea e te rererererererere rereke me te hanganga rereke te whakatika i te ara rere o te reo ki te iti rawa, na reira ka whakaiti i te parenga me te mate pehanga.
