Umenzi kunye nomcebisi wokukhetha iivalvu zepayipi kulawulo lolwelo lwamashishini
Singumenzi wevalvu yobuchwephesha abaneminyaka emininzi yemveliso kunye namava okuthumela ngaphandle. Siqhelene nolwakhiwo kunye nemigaqo yeevalvu ezahlukeneyo kwaye sinokukunceda ukhethe olona hlobo lwevalvu lufanelekileyo ngokwemibhobho yeendaba ezahlukeneyo kunye nokusingqongileyo. Siza kukunceda uchithe ixabiso elincinci ngelixa uhlangabezana ngokupheleleyo neemeko zokusetyenziswa kunye nokuqinisekisa ubomi benkonzo.
Iimeko zokusebenza ezisebenzayo zevalve
Iivalvu zethu zisetyenziswa kakhulu kwi-petroleum, kushishino lweekhemikhali, igesi yendalo, ukwenza iphepha, ukucocwa kwamanzi amdaka, amandla enyukliya, njl. Ezijoliswe kwiimeko zokusebenza ezinzima ezahlukeneyo, ezifana nobushushu obuphezulu, uxinzelelo oluphezulu, i-acidity eqinile, i-alkalinity enamandla, ukukhuhlana okuphezulu, njl. Iivalve zethu zinezinto ezininzi kakhulu. Ukuba ufuna ulawulo lokuqukuqela, ulawulo lobushushu, ulawulo lwe-pH, njl. njl
Iivalvu ze-NSW
I-NSW ithobela ngokungqongqo inkqubo yolawulo lwekhwalithi ye-ISO9001. Siqala ukusuka kwizikhewu zokuqala zomzimba wevalvu, isigqubuthelo sevalvu, amalungu angaphakathi kunye neziqhoboshi, emva koko siqhube, sihlanganise, sivavanye, sipeyinte, kwaye ekugqibeleni sipakishe kunye nenqanawa. Sivavanya ngononophelo ivalve nganye ukuqinisekisa ukuvuza kwe-valve ye-Zero kwaye ikhuselekile ukuyisebenzisa, umgangatho ophezulu, umgangatho ophezulu kunye nobomi obude.
Iimveliso zevalve ezisetyenziswa ngokuqhelekileyo kwimibhobho yoshishino
Iivalvu kwimibhobho yemizi-mveliso zizixhobo zombhobho ezisetyenziselwa ukuvula nokuvala imibhobho, ulawulo lokuhamba kolwalathiso, ukulungelelanisa nokulawula iiparamitha (ubushushu, uxinzelelo kunye nokuhamba) kwendlela ehanjiswayo. I-Valve licandelo lolawulo kwinkqubo yokuthutha ulwelo kwiipayipi zoshishino. Inemisebenzi yokuqhawula, ukunqunyulwa kwengxakeko, ukuvala, ukulawula, ukuguqulwa, ukuthintela ukuhamba okubuyela emva, ukunyanzeliswa koxinzelelo, ukuguqula okanye ukugqithiswa koxinzelelo kunye neminye imisebenzi yokulawula ulwelo. Ingasetyenziselwa ukulawula ukuhamba kweentlobo ezahlukeneyo zolwelo olunjengomoya, amanzi, umphunga, imithombo yeendaba eyonakalisayo, udaka, ioyile, intsimbi engamanzi kunye nemithombo yeendaba erediyo.
Iindidi zeevalvu zemibhobho yeshishini le-NSW
Iimeko zokusebenza kwimibhobho yemizi-mveliso zintsonkothile, ngoko ke i-NSW iyila, iphuhlisa, kwaye ivelise iindidi ngeendidi zezivalo zeendawo ezahlukeneyo zokusetyenziswa ukuhlangabezana nemisebenzi kunye neemfuno ezifunwa ngabasebenzisi ngexesha lokusetyenziswa.
Iivalvu ze-SDV
I-valve yeplagi ye-pneumatic idinga kuphela ukusebenzisa i-actuator ye-pneumatic ukujikeleza i-90 degrees kunye nomthombo womoya, kwaye i-torque ejikelezayo ingavalwa ngokuqinileyo.

Undoqo wevalve yibhola engqukuva enomngxuma. Ipleyiti ihambisa isiqu sevalve ukwenzela ukuba ukuvuleka kwebhola kuvuleke ngokupheleleyo xa ijongene ne-axis yombhobho, kwaye ivalwe ngokupheleleyo xa ijikwe ngama-90°. Ivalve yebhola inomsebenzi othile wohlengahlengiso kwaye inokuvala ngokuqinileyo.
Iivalve zebhabhathane
Undoqo wevalve yipleyiti yevalvu ejikelezayo ekwazi ukujikeleza i-axis ethe nkqo ukuya kwi-axis yombhobho. Xa iplani yeplate yevalve ihambelana ne-axis yombhobho, ivuleke ngokupheleleyo; xa iplani yepleyiti ye-butterfly valve i-perpendicular kwi-axis yombhobho, ivalwe ngokupheleleyo. Ivalve yebhabhathane ubude bomzimba buncinci kwaye ukuxhathisa kokuhamba kuncinci.
Ivalve yePlag
Ubume beplagi yevalve ingaba yi-cylindrical okanye i-conical. Kwiiplagi ze-valve ze-cylindrical, iziteshi zihlala zixande; kwiiplagi zevalve enetapered, iziteshi zitrapezoidal. Phakathi kwezinye izinto, i-valve yeplagi ye-DBB yimveliso ekhuphisana kakhulu yenkampani yethu.
Ivalve yeSango
Yahlulwe ibe yisiqu esivulekileyo kunye nesiqu esifihliweyo, isango elinye kunye nesango eliphindwe kabini, isango le-wedge kunye nesango elihambelanayo, njl., kwaye kukho ivalve yohlobo lwemela. Ubungakanani bomzimba wevalve yesango mncinci ecaleni kwendlela yokuhamba kwamanzi, ukuchasana nokuhamba kuncinci, kwaye isithuba sedayamitha yesango sikhulu.
Ivalve yeglowubhu
Isetyenziselwa ukuthintela umva we-medium, isebenzisa amandla e-kinetic yolwelo ngokwalo ukuze izivule, kwaye ivale ngokuzenzekelayo xa i-reverse flow isenzeka. Ihlala ifakwe kwi-outlet yepompo yamanzi, i-outlet ye-trap ye-steam kunye nezinye iindawo apho ukuhamba kwe-reverse yolwelo kungavumelekanga. Iivalvu zokujonga zahlulwe ngohlobo lokujingi, uhlobo lwepiston, uhlobo lokuphakamisa kunye nohlobo lwe-wafer.
