Injongo yokusebenzisa ivalvu yokukhangela kukuthintela ukuhamba okungasemva kwesixhobo, kwaye ivalvu yokukhangela idla ngokufakelwa kwindawo yokuphuma kwepompo. Ukongeza, kufuneka kufakwe ivalvu yokukhangela kwindawo yokuphuma yecompressor. Ngamafutshane, ukuze kuthintelwe ukuhamba okungasemva kwesixhobo, kufuneka kufakwe ivalvu yokukhangela kwizixhobo, isixhobo okanye umbhobho.
Ngokubanzi, iivalvu zokujonga ukuphakama ezithe nkqo zisetyenziswa kwimibhobho ethe tye enobubanzi obuqhelekileyo be-50mm. Ivalvu yokujonga ukuphakama ethe tye inokufakelwa kwimibhobho ethe tye nethe nkqo. Ivalvu esezantsi ifakwa kuphela kumbhobho othe nkqo wokungena kwepompo, kwaye i-medium iphuma ezantsi iye phezulu.
Ivalvu yokujonga i-Swing ingenziwa ibe noxinzelelo oluphezulu kakhulu lokusebenza, i-PN ingafikelela kwi-42MPa, kwaye i-DN nayo ingenziwa ibe nkulu kakhulu, ubuninzi bungafikelela ngaphezu kwe-2000mm. Ngokwezinto ezahlukeneyo zeqokobhe kunye nesitywino, ingafakwa kuyo nayiphi na indawo yokusebenza kunye nayo nayiphi na indawo yobushushu bokusebenza. Indawo yokusebenza ngamanzi, umphunga, igesi, indawo ebolayo, ioyile, ukutya, amayeza, njl. Ubushushu bokusebenza kwendawo yokusebenza buphakathi kwe -196 ~ 800℃.
Indawo yokufaka ivalvu yokujonga iswing ayikhawulelwanga, idla ngokufakelwa kumbhobho othe tye, kodwa ingafakelwa kumbhobho othe nkqo okanye kumbhobho othe tye.
Ithuba elifanelekileyo levalvu yokuhlola ibhabhathane luxinzelelo oluphantsi kunye nobubanzi obukhulu, kwaye ithuba lokufakela lilinganiselwe. Ngenxa yokuba uxinzelelo olusebenzayo lwevalvu yokuhlola ibhabhathane alunakuba phezulu kakhulu, kodwa ububanzi obuqhelekileyo bunokuba bukhulu kakhulu, obunokufikelela ngaphezulu kwe-2000mm, kodwa uxinzelelo oluqhelekileyo lungaphantsi kwe-6.4MPa. Ivalvu yokuhlola ibhabhathane inokwenziwa ibe luhlobo lwe-wafer, oluhlala lufakelwa phakathi kweeflanges ezimbini zombhobho ngendlela yoqhagamshelo lwe-wafer.
Indawo yokufaka ivalvu yokujonga ibhabhathane ayikhawulelwanga, ingafakwa kwipayipi ethe tye, kwipayipi ethe nkqo okanye kwipayipi ethe tye.
Ivalvu yokujonga i-diaphragm ifanelekile kwiipayipi ezichaphazeleka yihammer yamanzi. I-diaphragm ingayisusa kakuhle ihammer yamanzi ebangelwa kukuhamba okungasemva kwesixhobo. Ekubeni ubushushu bokusebenza kunye noxinzelelo lokusebenza lweevalvu zokujonga i-diaphragm zinqunyelwe zizinto ze-diaphragm, zihlala zisetyenziswa kwiipayipi ezinoxinzelelo oluphantsi kunye nobushushu obuqhelekileyo, ngakumbi kwiipayipi zamanzi empompini. Ngokubanzi, ubushushu bokusebenza besixhobo buphakathi kwe -20~120℃, kwaye uxinzelelo lokusebenza lungaphantsi kwe-1.6MPa, kodwa ivalvu yokujonga i-diaphragm inokufikelela kububanzi obukhulu, kwaye i-DN ephezulu ingaba ngaphezulu kwe-2000mm.
Ivalvu yokujonga i-diaphragm isetyenziswa kakhulu kwiminyaka yakutshanje ngenxa yokusebenza kwayo okugqwesileyo kokungena kwamanzi, ulwakhiwo olulula kunye neendleko eziphantsi zokuvelisa.
Ivalvu yokujonga ibhola isebenza kakuhle ekutywineni, isebenza ngokuthembekileyo kwaye inokumelana kakuhle nesando samanzi kuba isitywino singumbumba ogqunywe ngerabha; kwaye ngenxa yokuba isitywino sinokuba yibhola enye okanye iibhola ezininzi, singenziwa sibe nobubanzi obukhulu. Nangona kunjalo, isitywino saso singumbumba ongenanto ogqunywe ngerabha, ongafanelekanga kwimibhobho enoxinzelelo oluphezulu, kodwa ofanelekileyo kuphela kwimibhobho enoxinzelelo oluphakathi noluphantsi.
Ekubeni izinto zeqokobhe levalvu yokujonga ibhola zinokwenziwa ngentsimbi engagqwaliyo, kwaye i-sphere engenanto yesitywino inokugqunywa ngeplastiki yobunjineli ye-PTFE, ingasetyenziswa nakwiipayipi ezine-media erhabaxa ngokubanzi.
Ubushushu bokusebenza kolu hlobo lwevalvu yokujonga buphakathi kwe -101~150℃, uxinzelelo oluqhelekileyo yi ≤4.0MPa, kwaye uluhlu lobubanzi oluqhelekileyo luphakathi kwe 200~1200mm.
