Mahinga Nui V Ball Valve

Whakaahuatanga Poto:

Ko te paera o te paera V poihe mahi teitei he poi V, he momo mana hurihuri e whakahaere ana i te rere o te wai ma te huri i te waahi tapahi V. He pai rawa atu mo te whakahaere i nga purongo kei roto i nga muka, i nga kirikiri ranei, penei i te whakahaere i roto i nga tono penei i te whakaputa pepa penupenu, te maimoatanga parakaingaki, te pehanga hua hinu e whakapumau ana i te paipa kawe hinu, me etahi atu. Ko te mono ka whakaratohia ki te rakau hurihuri i nga pito o runga me raro. . Ka whakaratohia te nohoanga ki te mowhiti whakanui mo te whakahaere i te kaha hiri. Ka whakatuwherahia, ka kati ranei te puera, ka whakaputahia e te tapahi V te kaha kutikuti poro me te nohoanga, kia pai ake ai te mahi hiri ki tera o O poipoi, te paera kuaha, me etahi atu. Ko te nuinga o te waa e whakamahia ana i roto i nga umanga penei i te ahumahi petrochemical, pepa. & penupenu, ahumahi marama, maimoatanga wai, etc.

Whakarāpopototanga

Ko te tapahi V he nui te owehenga ka taea te whakarite me te rite o te paheketanga o te rere, me te mohio ki te mana o te pehanga me te rere.

Hanganga ngawari, iti te rōrahi, te taumaha marama, te hongere rere maeneene.

Ka whakaratohia he hanganga utu aunoa nati nui elastic kia pai ai te whakahaere i te mata hiri o te nohoanga me te mono me te mohio ki te mahi hiri pai. Ka taea e te mono me te hanganga nohoanga te whakaiti i te kakahu.

Ko te tapahanga V ka puta te kaha kutikuti poro ki te tuuru ki te kati i nga papapāho kei roto nga muka. He mea tino pai mo te whakatuwhera me te whakahaere i nga purongo teitei me nga papaa kei roto nga muka me nga kirikiri.
