Iimpawu zoyilo
1. uhlobo lomkhono wekhadi ukutywina okuthambileyo kweplagi yokutywina kwenziwa ngokutywinwa komphezulu ojikeleze iiseti zamakhadi, okukodwa kwe360 ° ukukhuselwa komlomo wesinyithi iiseti zamakhadi ezisisigxina;
2. Ivalve ayinamngxuma wokuqokelela imidiya;
3. Umlomo wesinyithi unika umsebenzi wokuzihlambulula kwinkqubo yokujikeleza, efanelekileyo kwi-viscous kunye neemeko ezilula ngokulula;
4. Ukuhamba ngeendlela ezimbini, kukulungele ngakumbi ukusebenzisa ukufakela;
5. Izinto eziphathekayo kunye nemilinganiselo ye-flange yamacandelo inokukhethwa ngokweemeko zangempela zokusebenza okanye iimfuno zabasebenzisi, kwaye ihlangabezane nazo zonke iintlobo zeemfuno zobunjineli.
Ivalve yeplagi yenkampani yeNewsway Valve yivalve ejikelezayo eneqhekeza lokuvala okanye iplunger.Ngokujikeleza i-90 degrees, i-port yeshaneli kwiplagi yevalve inxibelelana okanye yahlulwe kunye ne-channel port kumzimba wevalvu ukuqonda ukuvula okanye ukuvala.
Iplagi yevalve yayo ingaba yi-cylindrical okanye i-conical.Kwiiplagi ze-valve ze-cylindrical, iziteshi zihlala zixande;kwiiplagi zevalve yeconical, iziteshi zitrapezoidal.Ezi milo zenza ulwakhiwo lwevalve yeplagi lube khaphukhaphu.Iyona nto ifanelekileyo njenge-cut-off kunye ne-connection medium kunye ne-shunt, kodwa kuxhomekeke kwiipropati ezisebenzayo kunye nokuchasana nokukhukuliseka kwendawo yokutywinwa, ngamanye amaxesha ingasetyenziselwa ukuxubha.
Iivalvu zeplagi zihlelwa ngokosetyenziso: iivalvu zeplagi ezithambileyo, iivalve zeplagi ezithathiweyo ezilubricated hard, iivalvu zeplagi zokuphakamisa, iindlela ezintathu kunye neendlela ezine.
Iivalvu zeplagi ezitywinwe ngokuthambileyo zihlala zisetyenziswa kwindawo ezirhabaxa ezinje ngokutya, ityhefu ephezulu kunye nemithombo yeendaba eyingozi kakhulu, apho ukuvuza kuthintelwe ngokungqongqo, nalapho isixhobo sevalve singangcolisi imidiya.Umzimba we-valve unokukhethwa kwi-carbon steel, i-alloy steel kunye nensimbi engenasici ngokwendlela yokusebenza.
Iivalvu zeplagi ezithathiweyo eziqinileyo zinokwahlulwa zibe ziivalvu zeplagi ezithambisisiweyo eziqhelekileyo kunye noxinzelelo lweplagi elungeleleneyo.Igrisi ekhethekileyo itofwa ukusuka phezulu kumzimba weplagi phakathi komngxuma wekhowuni womzimba wevalve kunye nomzimba weplagi ukwenza ifilimu yeoli ukuze kuncitshiswe itorque yokuvula kunye nokuvala ivalve kunye nokuphucula ukusebenza kokutywinwa kunye nobomi benkonzo.Uxinzelelo olusebenzayo lunokufikelela kwi-64MPa, ubushushu obuphezulu bokusebenza bunokufikelela kuma-degrees angama-325, kunye nobukhulu obukhulu bunokufikelela kwi-600mm.
Iivalvu zeplagi zokuphakamisa zineendlela ezahlukeneyo zolwakhiwo.Xa i-valve ivuliwe, iplagi iphakanyisiwe, kwaye iplagi ijikelezwe ngama-degrees angama-90 ukuya ekuvuleni okupheleleyo kwevalve ukunciphisa i-friction kunye nomgangatho wokutywina we-valve body;xa i-valve ivaliwe, iplagi ijikelezwe ngama-90 degrees kwindawo evaliweyo.Lahla ukuze uqhagamshelane nomphezulu wokutywina womzimba wevalvu ukuphumeza ukutywinwa.
Iindlela ezintathu zokumisa ii-stopcocks zilungele ukutshintsha indlela yokuhamba okuphakathi okanye usasazo oluphakathi.Ngokweemfuno zeemeko zokusebenza, unokukhetha i-bushing ethambileyo yokutywina okanye ukutywinwa okuthambileyo, ivalve yeplagi yokutywina eqinileyo.
