Ko te DN50-DN400 Slight Resistance Non-return Flanged Backflow Preventer he tuku CE me te Tiwhikete ki te motu katoa.

Whakaahuatanga:

Ātete iti Ārai Rere Whakamuri Kore-Hoki (Momo Flanged) TWS-DFQ4TX-10/16Q-D - he momo taputapu whakahaere wai i hangaia e tā mātou kamupene, e whakamahia ana mō te tuku wai mai i te wāhanga tāone ki te wāhanga paru whānui, e whakawhāiti ana i te pēhanga o te paipa kia kotahi noa te ara o te rere o te wai. Ko tana mahi he ārai i te rere whakamuri o te puna paipa, i tetahi āhuatanga rānei o te miphon rere whakamuri, kia kore ai e para te rere whakamuri.

Ngā Āhuatanga:

1. He hanganga poto, he kiato hoki; he iti te ātete; he penapena wai (kāore he āhuatanga rerenga wai rerekē i te pikinga noa o te pēhanga o te tuku wai); he haumaru (mēnā he ngaronga pēhanga rerekē i roto i te pūnaha tuku wai pēhanga o runga, ka taea te whakatuwhera i te takirere rerenga wai i te wā tika, ka waatea, ā, ko te kōhao waenga o te aukati rere whakamuri te mea nui i te taha o runga i te wehewehe hau); te kimi me te tiaki ipurangi me ētahi atu. I raro i te mahi noa i roto i te tere rere ōhanga, ko te kino o te wai o te hoahoa hua he 1.8 ~ 2.5 m.

2. He iti te ātete rere o te hoahoa whānui o te takirere taki e rua ngā taumata, he tere te whakaweto i ngā hiri o te takirere taki, ka taea te ārai i ngā kino ki te takirere me te paipa i te pēhanga whakamuri ohorere, me te mahi wahangu, ka roa ake te ora o te takirere.

3. Mā te hoahoa tika o te takirere waikeri, ka taea te whakarerekē i te pēhanga waikeri i te uara o te piki me te heke o te pēhanga o te pūnaha tuku wai kua tapahia, kia kore ai e pokanoa ki ngā piki me ngā heke o te pēhanga o te pūnaha. Ka taea te whakaweto me te whakaweto me te haumaru, kāore he turuturu wai rerekē.

4. Nā te hoahoa nui o te kōhao whakahaere diaphragm, he pai ake te pono o ngā wāhanga matua i ērā o ētahi atu ārai whakamuri, ā, he haumaru, he pono hoki te whakaweto me te whakakā mō te takirere waikeri.

5. Kāore he raruraru waikeri i te hanganga whakakotahi o te whakatuwheratanga me te awaawa whakawhiti whānui, te whakaurunga me te rerenga tāpiri i roto i te kōhao takirere, ā, ka tino whakawhāiti i te tūponotanga o te hokinga whakamuri o te awa me te hurihanga o te rere o te siphon.

6. Ka taea te whakamātautau me te tiaki i te hoahoa tangata i runga ipurangi.

Ngā tono:

Ka taea te whakamahi i roto i te parahanga kino me te parahanga mārama, mō te parahanga paitini, ka whakamahia hoki mena kaore e taea te aukati i te rere whakamuri mā te wehe i te hau;
Ka taea te whakamahi i roto i te pūtake o te paipa peka i roto i te parahanga kino me te rere tonu o te pēhanga, ā, kāore e whakamahia hei aukati i te heke o te pehanga.
te parahanga paitini.
