Injongo yokusebenzisa akhangela ivalvekukuthintela ukubuyela umva kwesixhobo, kunye akhangela ivalveifakwe ngokubanzi kwindawo yokuphuma yempompo. Ukongeza, akhangela ivalveifakwe kwi-outlet ye-compressor. Ngamafutshane, ukuze kuthintelwe ukubuya umva kwendlela,khangela iivalvekufuneka ifakwe kwisixhobo, izixhobo okanye imibhobho.
Ngokuqhelekileyo, ukuphakamisa ngokuthe nkqokhangela iivalvezikhethwa kwimibhobho ethe tyaba ene-50mm ye-diameter. Ukuphakamisa ngokuthe ngqokhangela iivalveinokufakwa kuyo yomibini imigca ethe tye nethe nkqo. Ivalve yeenyawo ifakwe ngokubanzi kuphela kumgca othe nkqo we-inlet yempompo, kwaye i-medium ihamba ukusuka ezantsi ukuya phezulu.
Iivalve yokukhangela ujingiingenziwa ngoxinzelelo oluphezulu lokusebenza, i-PN ukuya kwi-42MPa, kunye ne-DN nayo ingaba nkulu kakhulu, ukuya kuthi ga kwi-2000mm. Ngokuxhomekeke kwizinto eziphathekayo zezindlu kunye nezitywina, nayiphi na indawo yokusebenza kunye naluphi na uhlobo lweqondo lokushisa lunokusetyenziswa. Okuphakathi ngamanzi, umphunga, igesi, i-oyile, ukutya, amayeza, njl.
Iivalve zokujonga ujingiinokufakwa kwiindawo ezingasikelwanga mda kwaye iqhele ukufakwa kwilayini ezithe tye, kodwa inokufakwa kwilayini ethe nkqo okanye etyekelelweyo.
Iivelufa yokujonga ibhabhathaneifanelekile kuxinzelelo oluphantsi kunye nobukhulu obukhulu, kwaye imeko yokufakela iyancipha. Ngenxa yokuba uxinzelelo lokusebenza lweivelufa yokujonga ibhabhathaneayinakuba phezulu kakhulu, kodwa i-diameter ye-nominal ingaba nkulu kakhulu, inokufikelela ngaphezu kwe-2000mm, kodwa uxinzelelo lwegama lungaphantsi kwe-6.4MPa. Iivelufa yokujonga ibhabhathaneingenziwa ibe luhlobo lwe-clamp edityanisiweyo, ethi ifakwe ngokubanzi phakathi kweeflange ezimbini zombhobho, kwaye yamkele imo yoqhagamshelo lwe-clamp ezibini.
Iivelufa yokujonga ibhabhathaneinokufakwa kwindawo engenamkhawulo kwaye inokufakwa kumgca othe tye, othe nkqo okanye othotyiweyo.
I-diaphragmkhangela iivalvezilungele imibhobho eqhelene nehamile yamanzi, kwaye i-diaphragm inokuphelisa kakuhle ihamile yamanzi xa isiphakathi sihamba ngokuchasene nokuhamba. Ngenxa yobushushu bokusebenza kunye nokusetyenziswa koxinzelelo lwe-diaphragmkhangela iivalvezilinganiselwe ngezixhobo ze-diaphragm, zisetyenziswa ngokubanzi kwimibhobho yobushushu obuphantsi obuphantsi koxinzelelo, ngakumbi ilungele imibhobho yamanzi. Ngokuqhelekileyo, iqondo lokushisa eliphakathi liphakathi kwe -20 ~ 120 ° C, kunye noxinzelelo lokusebenza <1.6MPa, kodwa i-diaphragmkhangela ivalveinokufezekisa i-caliber enkulu, kwaye i-DN ingaba ngaphezu kwe-2000mm.
I-diaphragmkhangela iivalvezisetyenziswe kakhulu kwiminyaka yakutshanje ngenxa yokusebenza kwazo okugqwesileyo kokungangeni manzi, ubume obulula ngokwentelekiso kunye neendleko eziphantsi zokwenziwa.
Ibholakhangela ivalvekuba itywina yibhola egqunywe ngerabha, ngoko ke ukusebenza kokutywina kulungile, ukusebenza kuthembekile, kwaye ukuxhathisa ukothuka kwamanzi kulungile; Kwaye ngenxa yokuba itywina ingaba yibhola enye, okanye ingenziwa kwiibhola ezininzi, ngoko ke inokwenziwa ibe yi-diameter enkulu. Nangona kunjalo, izitywina zayo ziyimibhobho egobileyo eboshwe ngerabha, engafanelekanga kwimibhobho yoxinzelelo oluphezulu, efanelekileyo kuphela kwimibhobho ephakathi kunye nephantsi.
Ekubeni izinto zezindlu zebholakhangela ivalveingenziwa ngentsimbi engenasici, kwaye ibhola enomngxuma wokutywina ingagqunywa ngeplastiki yobunjineli be-PTFE, ingasetyenziselwa kumbhobho wemithombo yeendaba ezonakalisayo.
Ukushisa okusebenzayo kolu hlobo lwe-valve yokutshekisha phakathi kwe--101 ~ 150 ° C, uxinzelelo lwayo oluqhelekileyo luyi-≤4.0MPa, kunye noluhlu lwe-diameter ye-nominal luphakathi kwe-200 ~ 1200mm.
