Ngaba kukho naziphi na iimfuneko zokufakela isalathiso seevalvu zebhabhathane?

Umkhombandlela wofakelo weivelufa butterflykufuneka kumiselwe ngokohlobo lwazo kunye neemeko zokusebenza. Iivalvu zebhabhathane ezitywiniweyo ezikwi-Bidirectional azinazo iimfuno ezingqongqo, kodwa kukho izikhokelo zokufakela ezicetyiswayo; Ivalve yebhabhathane yendlela enye etywiniweyo kufuneka ifakwe kwicala eliboniswe lutolo, kwaye icala lesiqu sevalve kufuneka lithintele ukubheka ezantsi ukuqinisekisa ukusebenza okukhuselekileyo kunye nokusebenza kokutywinwa.

Iivalve zebhabhathane zohlulwe zibe zintlobo ezimbini: ukutywina okuphindwe kabini kunye nokutywinwa ngokulinganayo. Kuba itywiniwe kabiniiivalve butterfly, ngokwethiyori akukho zithintelo ezingqongqo zomkhombandlela kufakelo, kodwa kukho izikhokelo zokufakela ezicetyiswayo kubunjineli obusebenzayo. Umzekelo, kumbhobho othe tyaba, indlela yesikhondo sevalve inokukhethwa ngokolandelelwano oluthe nkqo ukuya phezulu, oluthe tye, kunye ne-45 ° ukuya phezulu. Le ndlela yokufakela kulula ukuyisebenzisa kwaye inokuqinisekisa ukufana kwetywina. Kwiivalvu zebhabhathane ezinobubanzi obukhulu (ezifana ne-DN500 nangaphezulu), kuyacetyiswa ukuba ufakele umzimba wevalve ngokuthe tye kunye ne-actuator engentla ukuthintela impembelelo yobunzima bepleyiti yevalve kwitorque. Ukuba umbhobho wemibhobho unentlenga (efana nodaka, isanti, namanzi), kucetyiswa ukuba ukuhamba okuphakathi kungene ukusuka kwicala elingasemva lepleyiti yevalve umphezulu wokuvala umphezulu wokuvala ukuguga nokwandisa ubomi bevalvu.

Ukufakwa kwendlela enye etywiniweyoiivalve butterflyineemfuno ezicacileyo zolwalathiso. Umzimba wevalvu uqhele ukuphawulwa ngophawu lwentolo, kwaye icala lotolo kufuneka lihambelane necala lokuhamba lendawo ephakathi kumbhobho ngexesha lofakelo, kungenjalo kunokubangela ukusilela kwetywina okanye ukuvuza okuphakathi.

Zombini iivalvu zebhabhathane ezijika macala omabini kunye ne-unidirectional azivumelekanga ukuba zifakwe ngokuthe nkqo ezantsi kwicala lesiqu sevalve. Ukuba isiqu sevalve sijonge ezantsi, umbhobho ophakathi unokuvuza ukusuka kwisikhondo sevalvu, ngakumbi xa uthutha i-asidi, i-alkaline, kunye nemithombo yeendaba eyityhefu, nto leyo ebeka isoyikiso kukhuseleko lobuqu lwabasebenzi. Ukongezelela, ukufaka i-valve stem ezantsi kuya kwandisa ubunzima bokusebenza, kufuna ukuba umqhubi aphakamise intloko yakhe yokusebenza, engahambelani noyilo lwe-ergonomic.

Indawo yokubeka iivalve zebhabhathane kufuneka kube lula ukusebenza. Umqheba okanye ivili lesandla leevalve zebhabhathane ngokuqhelekileyo li-1.2 yeemitha ukusuka kumgangatho wokusebenza, malunga nesikhundla sesifuba, esenza ukuvula kunye nokuvala kube nzima ngakumbi. Ukuba ivalve ifakwe phantsi, isondo lesandla okanye isibambo kufuneka sijonge phezulu kwaye singathambeki; Ukuba ifakwe eludongeni okanye kwisixhobo, shiya indawo yokuma ukuze abaqhubi baphephe ukusebenza ukusuka esibhakabhakeni.
