Iimpawu kunye nokuqwalaselwa kokhuseleko lweivelufa butterfly yombanephantsi kobushushu obuphezulu kunye nendawo yoxinzelelo oluphezulu

Ivalve yebhabhathane yombane sisixhobo sevalvu esetyenziswa ngokuqhelekileyo, esetyenziswa kakhulu kwipetroleum, kwikhemikhali, kumachiza nakwamanye amashishini. Kwezinye iimeko zokushisa okuphezulu kunye noxinzelelo oluphezulu, iimpawu kunye nokukhuselwa kwevalve yebhabhathane yombane kubaluleke kakhulu, eli phepha liya kwenza uhlalutyo olufutshane lwezi ngxaki.

Okokuqala, iimpawu ze-valve ye-butterfly yombane kwiqondo lokushisa eliphezulu kunye noxinzelelo oluphezulu

1. Ukumelana nobushushu obuphezulu

Ngaphantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu, izinto zevalve yebhabhathane yombane zihlala zenziwe ngealloys ezikhethekileyo, iiseramikhi zobushushu obuphezulu, insimbi engenasici kunye nezinye izinto, kwaye isixhobo ngokwaso sinokumelana nobushushu obuphezulu kwaye sinokusebenza ixesha elide. indawo yobushushu obuphezulu ngaphezu kwama-600 degrees.

2. Ukusebenza kokutywinwa okugqwesileyo

Ngaphantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu, amandla okutywinwa kwevalve yebhabhathane yombane sisitshixo sokuqinisekisa ukusebenza okukhuselekileyo nokuzinzileyo kwezixhobo. Iivalvu zebhabhathane zombane zihlala zisebenzisa i-carbide enesamente (efana ne-molybdenum alloy) into yokutywina, enokumelana okugqwesileyo kokunxiba, ukumelana nokudleka kunye nokumelana nobushushu obuphezulu.

3. Ulawulo oluchanekileyo

Ivalve yebhabhathane yombane ineempawu zokuchaneka okuphezulu kunye novelwano oluphezulu, kwaye inokulawula ngokufanelekileyo ukuhamba kunye nokuhamba kwemeko yolwelo phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu, ukuze kuqatshelwe ulawulo oluzenzekelayo lwenkqubo yokuvelisa.

Okwesibini, ukuqwalaselwa kokhuseleko lwevalve yebhabhathane yombane kwindawo yobushushu obuphezulu kunye noxinzelelo oluphezulu

1. Ukulawula ubushushu

Kwiindawo zokushisa eziphezulu kunye noxinzelelo oluphezulu, ukusetyenziswa kwee-valve ze-butterfly zombane kufuna ukulawulwa ngokuchanekileyo kweqondo lokushisa kwendawo yenkqubo ukuphepha iziphumo ezibi ezifana nokuguqulwa kwezinto eziphathekayo, ukunciphisa ukusebenza kokutywinwa, kunye nokulimala kwezixhobo ngenxa yokushisa okugqithisileyo.

2. Ukhuseleko lokhuseleko

Kwiqondo lokushisa eliphezulu kunye neendawo zoxinzelelo oluphezulu, ukukhuselwa kokhuseleko lwee-valve ze-butterfly zombane nazo zifuna ingqalelo ekhethekileyo. Ngokuqhelekileyo impahla yevalve esebenza kakuhle yokutywinwa, ukusebenza kakuhle kwefuthe eliphantsi lobushushu obuphantsi kunye nokusebenza kakuhle komlilo kunye nokudubula kokudubula kuyasetyenziswa; Kwaye ulungiselele isixhobo se-alamu esihambelanayo kunye namanyathelo okuthintela ukuthintela ingozi ebangelwa yinkqubo engaqhelekanga phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu.

3. Yenza ulondolozo rhoqo

Kwiqondo lokushisa eliphezulu kunye noxinzelelo oluphezulu, i-valve ye-butterfly yombane inokubangela ukuguqulwa kwezinto, ukunciphisa ukusebenza kokutywinwa, umonakalo wezixhobo kunye nezinye iingxaki ngenxa yokushisa kwexesha elide kunye nokusetyenziswa koxinzelelo oluphezulu. Ngoko ke, izixhobo zigcinwa rhoqo kwaye iindawo ezigugileyo zitshintshwa ukuze kuqinisekiswe ukusebenza kwayo okukhuselekileyo nokuthembekileyo.

Ngamafutshane, kwindawo yokushisa ephezulu kunye noxinzelelo oluphezulu, i-valve ye-butterfly yombane ineempawu zokumelana nokushisa okuphezulu, ukusebenza kokutywinwa okugqwesileyo kunye nokulawula okuchanekileyo, okwenza ukuba isetyenziswe ngokubanzi kwi-petroleum, imichiza, amayeza kunye namanye amashishini. Ngelo xesha, ukhuseleko kunye nokuzinza kwe-valve ye-butterfly yombane nayo kufuneka ihlonyelwe ukubaluleka okukhulu, kunye nokusetyenziswa kweendlela ezichanekileyo zokusetyenziswa kunye nokukhusela ukhuseleko kunokudlala kakuhle umphumo wesicelo se-valve butterfly valve.
