Injongo yokusebenzisa ivalvu yokukhangela kukuthintela ukubuya kwamanzi kwi-medium. Ngokubanzi, kufuneka kufakwe ivalvu yokukhangela kwindawo yokuphuma kwepompo. Ukongeza,kufuneka kufakwe ivalvu yokujonga kwindawo yokuphuma yecompressorNgamafutshane, ukuze kuthintelwe ukubuya kwamanzi kwesi sixokelelwano, kufuneka kufakwe ivalvu yokukhangela kwizixhobo, isixhobo okanye umbhobho. Ngokubanzi, ivalvu yokukhangela ukuphakama ethe nkqo isetyenziswa kumbhobho othe tye onobubanzi obuqhelekileyo be-50mm. Iivalvu zokukhangela ukuphakama ezithe tye zinokufakwa kwimibhobho ethe tye nethe nkqo. Ivalvu esezantsi ngokubanzi ifakwe kuphela kumbhobho othe nkqo kwindawo yokungena yepompo, kwaye esi sixokelelwano sihamba ukusuka ezantsi ukuya phezulu. Ivalvu yokujonga ukujika ingenziwa ibe luxinzelelo oluphezulu kakhulu lokusebenza, i-PN inokufikelela kwi-42MPa, kwaye i-DN nayo ingaba nkulu kakhulu, ukuya kuthi ga kwi-2000mm nangaphezulu. Ngokuxhomekeke kwizinto ezikwiqokobhe kunye nesitywino, ingasetyenziselwa nayiphi na indawo yokusebenza kunye nayo nayiphi na indawo yobushushu bokusebenza. Esi sixokelelwano ngamanzi, umphunga, igesi, indawo ebolayo, ioyile, ukutya, amayeza, njl. Uluhlu lobushushu bokusebenza oluphakathi luphakathi kwe -196 ~ 800℃. Indawo yokufaka ivalvu yokujonga ukujika ayithintelwanga. Ihlala ifakwe kumbhobho othe tye, kodwa ingafakwa nakwimbhobho ethe nkqo okanye umbhobho othambekileyo.

Iziganeko ezifanelekileyo zeivalvu yokujonga ibhabhathanezinoxinzelelo oluphantsi kwaye zinobubanzi obukhulu, kwaye amaxesha okufakelwa alinganiselwe. Ngenxa yokuba uxinzelelo olusebenzayo lwevalvu yokujonga ibhabhathane alunakuba phezulu kakhulu, kodwa ububanzi obuqhelekileyo bunokuba bukhulu kakhulu, obunokufikelela ngaphezulu kwe-2000mm, kodwa uxinzelelo oluqhelekileyo lungaphantsi kwe-6.4MPa. Ivalvu yokujonga ibhabhathane inokwenziwa ibe luhlobo lwe-clamp, oluhlala lufakelwa phakathi kwee-flanges ezimbini zombhobho, kusetyenziswa uhlobo loqhagamshelo lwe-clamp. Indawo yokufakela ivalvu yokujonga ibhabhathane ayithintelwanga. Ingafakelwa kumbhobho othe tye, okanye kumbhobho othe nkqo okanye kumbhobho othambekileyo.
Ivalvu yokujonga i-diaphragm ifanelekile kwiipayipi ezixhaphake kakhulu kwihammer yamanzi. I-diaphragm ingayisusa kakuhle ihammer yamanzi ebangelwa kukubuyela umva kwesixhobo. Ngenxa yokuba ubushushu bokusebenza kunye noxinzelelo lokusetyenziswa kwevalvu yokujonga i-diaphragm zinqunyelwe zizinto ze-diaphragm, isetyenziswa ngokubanzi kwiipayipi ezinoxinzelelo oluphantsi kunye nobushushu obuqhelekileyo, ngakumbi ezifanelekileyo kwiipayipi zamanzi empompini. Ubushushu obuqhelekileyo bokusebenza buphakathi kwe--20~120℃, kwaye uxinzelelo olusebenzayo luyi-<1.6MPa, kodwa ivalvu yokujonga i-diaphragm inokwenziwa ngobubanzi obukhulu, kwaye i-DN ephezulu inokufikelela ngaphezulu kwe-2000mm. Iivalvu zokujonga i-diaphragm zinokumelana okuhle kwehammer yamanzi, isakhiwo esilula kunye neendleko eziphantsi zokuvelisa, ngoko ke zisetyenziswe kakhulu kwiminyaka yakutshanje.
Ukususela ekutywinweni kweivalvu yokujonga ibhola yingqukuva egqunywe ngerabha, inamandla okuvala kakuhle, isebenza ngokuthembekileyo kwaye inokumelana kakuhle nesando samanzi; kwaye ekubeni isitywino sinokuba yibhola enye okanye iibhola ezininzi, singenziwa sibe nobubanzi obukhulu. Nangona kunjalo, isitywino saso sisikwere esingenanto esigqunywe ngerabha, esingafanelekanga kwiipayipi ezinoxinzelelo oluphezulu, kodwa kuphela kwiipayipi ezinoxinzelelo oluphakathi noluphantsi. Ekubeni izinto zeqokobhe levalvu yokujonga ibhola zinokwenziwa ngentsimbi engatyiwayo, kwaye isikwere esingenanto sesitywino sinokugqunywa ngeplastiki yobunjineli be-polytetrafluoroethylene, singasetyenziswa nakwiipayipi ezinemidiya 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.
