IMIBUZO EBUZWA QHO

Ithini indlela yokuvavanya uxinzelelo lwevalvu yesango?

Isango liyi-headstock ram, kwaye i-motion direction ye-valve disc ihambelana ngqo necala lolwelo, kwaye i-valve inokuvuleka ngokupheleleyo kwaye ivalwe ngokupheleleyo, ayinakulungiswa kwaye i-throttle ayinakulungiswa. I-gate valve ivalwe ngesihlalo se-valve kunye ne-valve disc, ngokuqhelekileyo umphezulu wokutywina uya kudlula izinto zesinyithi ukwandisa ukumelana nokuguguleka, okufana nomphezulu we-1Cr13, i-STL6, intsimbi engagqwaliyo njalo njalo. I-disc ine-rigid disc kunye ne-elastic disc. Ngokomahluko we-disc, ii-gate valves zahlulwe zibe zii-rigid gate valves kunye nee-elastic gate valves.

indlela yokuvavanya uxinzelelo lwevalvu yesango

Okokuqala, idiski iyavulwa, ukuze uxinzelelo olungaphakathi kwivalvu lunyuke luye kwixabiso elichaziweyo. Emva koko, vala iram, susa ivalvu yesango ngoko nangoko, jonga ukuba kukho ukuvuza kumacala omabini ediski, okanye ufake ngokuthe ngqo i-test medium kwixabiso elichaziweyo kwiplagi yesiciko sevalvu, kwaye ujonge itywina kumacala omabini ediski. Le ndlela ingentla ibizwa ngokuba luxinzelelo lovavanyo oluphakathi. Le ndlela ayifanelekanga kuvavanyo lwetywina lwevalvu yesango phantsi kobubanzi obuqhelekileyo be-DN32mm.

Enye indlela kukuvula idiski ukuze uxinzelelo lovavanyo lwevalvu lunyuke luye kwixabiso elichaziweyo; uze ucime idiski, uvule ipleyiti engaboniyo kwelinye icala, uze ujonge ukuvuza kobuso besitywino. Emva koko ubuyele umva, uphinde uvavanyo ude luqinisekiswe njengoko kuchaziwe apha ngasentla.

Uvavanyo lokutywina ekuzalisweni nasekugasketweni kwevalvu yomoya kufuneka lwenziwe ngaphambi kovavanyo lokutywina kwidiski.

Umgaqo wokusebenza we-actuator yombane
I-actuator yombane yindibaniselwano ye-actuator kunye ne-valve yokulawula kwinkqubo yolawulo oluzenzekelayo. Indima yayo kwinkqubo yolawulo oluzenzekelayo kukwamkela isignali evela kumlawuli, kwaye ngokwendawo yayo kunye neempawu zayo kwimibhobho yenkqubo, ukulawula ukuhamba kwemidiya yenkqubo ukulawula inkqubo yemveliso ngaphakathi koluhlu olufunekayo.
Indlela yokugcina nokugcina ivalvu?
Ukuze kuqhubeke ixesha elide ukusebenza okuqhelekileyo, kuyimfuneko ukuba kubekho ulondolozo oluqhubekayo kunye nolawulo olungqongqo lwazo zonke izixhobo kunye nezixhobo.Iivalvu zeJinbin zidibene nezi zixhobo kunye nezixhobo
Ukuze idlale ukusebenza kwayo kolawulo lweendawo eziyimfuneko, ke ngoko,Iivalvu zeJinbinkufuneka ithathwe njengengxaki epheleleyo yokugcinwa nolawulo.
Ivalve yeJinbinUlondolozo
IiJinbin Valve zizinto ezibalulekileyo ezidibanisa ezi zixhobo kunye nezixhobo kunye kwaye zidlala ukusebenza kwazo kolawulo, ngoko ke kufuneka ziqwalasele imiba yolondolozo kunye nolawulo iyonke.
 
Ukugcinwa kweivalvuuseluvalelweni
Xa ivalvu ithuthwa iye kwindawo yokugcina impahla, umgcini kufuneka afike ngexesha elifanelekileyo kwiinkqubo zokugcina, nto leyo elungele ukuhlolwa nokugcinwa kwevalvu. Umgcini kufuneka ajonge ngononophelo iinkcukacha zemodeli yevalvu, ajonge ukubonakala komgangatho wevalvu, aze ancede abahloli bevalvu ngaphambi kovavanyo lwamandla okugcina kunye novavanyo lokutywina. Ukuhlangabezana nemigangatho yokwamkelwa kwevalvu, inokuphathwa kwiinkqubo zokugcina; ukusilela kufuneka kugcinwe ngokufanelekileyo, ukuze kujongwane nako ngamasebe afanelekileyo.
Kwithala leencwadi levalvu, ukuze usule ngononophelo, ucoce ivalvu kwinkqubo yokuthutha amanzi nothuli, umphezulu olula ukugqwala, isiqu, umphezulu wokutywina kufuneka ugqunywe ngomaleko wearhente yokulwa nomhlwa okanye uncamathisele umaleko wephepha elilwa nomhlwa ukuze likhuselwe; indlela yokungena kunye nemijelo yokuphuma kwevalvu kufuneka isebenzise iplastiki okanye iphepha lewax ukuze livalwe, ukuze lingangeni mdaka.
Ugcino lwezinto kufuneka lwenziwe ngokuhambelana nobukhulu kunye nobukhulu bomyalelo, ukukhutshwa kwezinto ezishelufini; iivalvu ezinkulu zinokukhutshwa kwindawo yokugcina impahla esemhlabeni, ngokweemfuno zemodeli. Zibekwe zibe ziingceba. Ivalvu kufuneka ibekwe ime nkqo, ingadibani nomphezulu wokutywina weflange nomhlaba, kodwa ingavumelekanga ukuba ihlangane.
Ukuze ivalvu igcinwe ikwimeko entle, ukongeza kwimfuneko yendawo yokugcina impahla eyomileyo nengena umoya, ecocekileyo necocekileyo, kufuneka kubekho iseti yenkqubo yolawulo yesayensi ephucukileyo, enolwazi oluphezulu, ekufuneka ihlolwe rhoqo.
Ukusetyenziswa ixesha elide kwevalvu, ukuba ukusetyenziswa kwe-asbestos packing kusetyenziswa, kufuneka i-asbestos packing isuswe kwileta yokupakisha, ukuze kuthintelwe ukubola kweekhemikhali ze-elektroniki, umonakalo kwisiqu.
Ngaphezu kwemigaqo yokusetyenziswa kwezinto zokuthintela umhlwa, izinto zokuthambisa, kufuneka zitshintshwe rhoqo okanye zongezwe.
Yintoni umgaqo osebenzayo wevalvu yebhabhathane?

Umsebenzi ufana nalowo we-ivalvu yebhola, nto leyo evumela ukuvalwa ngokukhawuleza. Iivalvu zebhabhathaneZithandwa kakhulu kuba zibiza kancinci kunezinye iindlela zoyilo lweevalvu, kwaye zilula ngoko ke azidingi nkxaso ingako. Idiski ibekwe embindini wepayipi. Intonga idlula kwidiski iye kwi-actuator engaphandle kwevalvu. Ukujikeleza i-actuator kuguqula idiski nokuba ihambelana okanye ijikeleze ngqo kwi-flow. Ngokungafaniyo nevalvu yebhola, idiski ihlala ikhona ngaphakathi kwi-flow, ngoko ke ibangela ukwehla koxinzelelo, nokuba ivuliwe.

Ivalvu yebhabhathane ivela kusapho lweevalvu ezibizwa ngokuba ziivalvu zekota. Xa isebenza, ivalvu ivuleka ngokupheleleyo okanye ivaliwe xa idiski ijikeleziswa ngekota. "Ibhabhathane" yidiski yesinyithi efakwe kwinduku. Xa ivalvu ivaliwe, idiski ijikeleziswa ukuze ivale ngokupheleleyo indlela. Xa ivalvu ivuliwe ngokupheleleyo, idiski ijikeleziswa ngekota ukuze ivumele indlela engathintelwanga yolwelo. Ivalvu inokuvulwa kancinci kancinci ukuze ithontsize.

Kukho iintlobo ezahlukeneyo zeevalvu zebhabhathane, nganye ilungele uxinzelelo olwahlukeneyo kunye nokusetyenziswa okwahlukileyo. Ivalvu yebhabhathane ye-zero-offset, esebenzisa ukuguquguquka kwerabha, inezinga eliphantsi loxinzelelo. Ivalvu yebhabhathane ye-double offset esebenza kakhulu, esetyenziswa kwiinkqubo zoxinzelelo oluphezulu kancinci, isuswa kumgca ophakathi wesihlalo sediski kunye nesitywino somzimba (i-offset yokuqala), kunye nomgca ophakathi webhore (i-offset yesibini). Oku kudala isenzo sekhamera ngexesha lokusebenza ukuphakamisa isihlalo siphume kwisitywino okubangela ukungqubana okuncinci kunokuba kudalwe kuyilo lwe-zero offset kwaye kunciphisa ukuthambekela kwayo kokuguguleka. Ivalvu efanelekileyo kakhulu kwiinkqubo zoxinzelelo oluphezulu yivalvu yebhabhathane ye-triple offset. Kule valve i-axis yoqhagamshelwano lwesihlalo sediski iyasuswa, esebenza ukuphelisa unxibelelwano olutyibilikayo phakathi kwediski kunye nesihlalo. Kwimeko yeevalvu ze-triple offset, isihlalo senziwe ngentsimbi ukuze sikwazi ukwenziwa ngomatshini ukuze sivale i-bubble tight xa sidibana nediski.

Kutheni iValve yam ivuza?

Iivalvu zinokuvuza ngezizathu ezahlukeneyo, kuquka:

  • Ivalvu yiayivalwanga ngokupheleleyo(umz., ngenxa yokungcola, inkunkuma, okanye olunye uhlobo lokuphazamiseka).
  • Ivalvu yiyonakeleUkonakala kwesihlalo okanye isitywini kunokubangela ukuvuza.
  • Ivalvu yiayenzelwanga ukuvala ngokupheleleyoIivalvu ezenzelwe ulawulo oluchanekileyo ngexesha lokuqhobosha zisenokungabi nabuchule bubalaseleyo bokuvula/ukucima.
  • Ivalvu yiubungakanani obungalungangayeprojekthi.
Loluphi ulwazi endiludingayo ukuze ndikwazi ukwenza ubungakanani obufanelekileyo kwaye ndikhethe ivalvu?
Kufuneka ulwazi olusisiseko oluthandathu ukuze ukhethe ubungakanani kunye nevalvu yokhuseleko okanye yokunciphisa uxinzelelo:

  1. Ubungakanani boqhagamshelo kunye nohlobo
  2. Uxinzelelo olusetiweyo (psig)
  3. Ubushushu
  4. Uxinzelelo lomqolo
  5. Inkonzo
  6. Umthamo ofunekayo
