Ithini indlela yovavanyo loxinzelelo lwevalvu yesango?

Isango yinkunzi yegusha, kwaye isalathiso sentshukumo yediski yevalve i-perpendicular ukuya kwicala lolwelo, kwaye ivalve inokuvulwa ngokupheleleyo kwaye ivalwe ngokupheleleyo, ayinakulungiswa kunye ne-throttle. I-valve yesango ivalwe ngesihlalo se-valve kunye ne-disc ye-valve, ngokuqhelekileyo indawo yokutywina iya kukhwela izinto zetsimbi ukuze kwandiswe ukunyanzeliswa kokugqoka, njenge-surfacing 1Cr13, STL6, insimbi engenasici kunye nokunye.I-disc ine-disc eqinile kunye ne-elastic disc. Ngokomahluko we-disc, iivalve zesango zihlulwe zibe zi-valve zesango eziqinileyo kunye ne-elastic gate valves.

indlela yokuvavanya uxinzelelo lwevalve yesango

Okokuqala, i-disc ivuliwe, ukwenzela ukuba uxinzelelo ngaphakathi kwevalve lukhuphuke kwixabiso elichaziweyo. Emva koko, vala inkunzi yegusha, susa ngokukhawuleza i-valve yesango, khangela ukuba kukho ukuvuza kumacala amabini e-disc, okanye ungene ngokuthe ngqo kwi-test medium kwixabiso elichaziweyo kwiplagi yesivalo se-valve, kwaye khangela isitywina kumacala omabini e-disc. Le ndlela ingasentla ibizwa ngokuba luxinzelelo lovavanyo oluphakathi. Le ndlela ayifanelekanga uvavanyo lokutywinwa kwevalve yesango phantsi kobubanzi obubizwa ngokuba yi-DN32mm.

Enye indlela kukuvula i-disc ukwenza i-valve yovavanyo loxinzelelo lukhuphuke kwixabiso elichaziweyo; uze ucime i-disc, vula ipleyiti eyimfama kwelinye icala, kwaye ukhangele ukuvuza kobuso betywina. Emva koko ubuyele umva, phinda uvavanyo de ube ufanelekile njengoko kungentla.

Uvavanyo lokutywinwa ekuzalweni kunye ne-gasket ye-valve ye-pneumatic kufuneka iqhutywe phambi kovavanyo lokutywinwa kwediski.

Umgaqo osebenzayo we-actuator yombane
I-actuator yombane indibaniselwano ye-actuator kunye nevalve yokulawula kwinkqubo yokulawula ngokuzenzekelayo. Indima yayo kwinkqubo yokulawula ngokuzenzekelayo kukwamkela umqondiso ovela kumlawuli, kunye nesikhundla sayo kunye neempawu kwinkqubo yokubhobhoza, ukulawula ukuhamba kwenkqubo yemidiya yokulawula inkqubo yokuvelisa ngaphakathi koluhlu olufunekayo.
Indlela yokugcina nokugcina ivalve?
Ukuze kuqhutywe umsebenzi oqhelekileyo wexesha elide, kuyimfuneko ukugcinwa rhoqo kunye nokulawulwa okungqongqo kuzo zonke izixhobo kunye nezixhobo.Iivalvu zeJinbin ziqhagamshelwe kwezi zixhobo kunye nezixhobo
Ukudlala ukusebenza kwayo kolawulo lwamacandelo ayimfuneko, ke ngoko,Iivalvu zeJinbinkufuneka kuthathelwe ingqalelo ugcino olubanzi kunye nengxaki yolawulo.
Iivalvu zeJinbin zizinto eziyimfuneko ezidibanisa ezi zixhobo kunye nezixhobo kunye kwaye zidlale ukusebenza kwazo zolawulo, kwaye ke kufuneka zithathele ingqalelo ukugcinwa kunye nemiba yolawulo ngokubanzi.
 
Ugcino lweivalveeluvalelweni
Ukuthuthwa kweValve kwindawo yokugcina impahla, umgcini kufuneka abe ngexesha elifanelekileyo kwiinkqubo zokugcina, ezihambelana nokuhlolwa kunye nokugcinwa kwevalve. Umlondolozi kufuneka ajonge ngononophelo imodeli yevalvu, ajonge inkangeleko yevalvu yevalvu, kunye nokuncedisa abahloli bevalve phambi kovavanyo lwamandla okugcina kunye novavanyo lokutywina. Hlangana nemilinganiselo yokwamkelwa kwevalve, inokuphathwa kwiinkqubo zokugcina; ukusilela kwakhona kufuneka kugcinwe ngokufanelekileyo, ukuze kusingathwe ngamasebe achaphazelekayo.
Kwithala leencwadi levalve, ukusula ngononophelo, ukucoca ivalve kwinkqubo yothutho lwamanzi kunye nothuli lokungcola, kulula ukugqwala umphezulu, isiqu, indawo yokutywina kufuneka igqunywe ngomaleko we-anti-rust okanye uncamathisele umaleko wephepha le-anti-Rust ukuze ukhuselwe; i-valve yokungena kunye nemijelo yokukhupha ukusebenzisa isigqubuthelo seplastiki okanye iphepha le-wax ukuba livalwe, ukuze ungangeni ukungcola.
Uluhlu kufuneka lwenziwe ngokuhambelana nobukhulu kunye nobukhulu bomyalelo, ukukhutshwa kwiishelufu; iivalve ezinkulu zinokukhutshwa kwindawo yokugcina impahla emhlabeni, ngokuhambelana nemodeli yenkcazo ebekwe ngamaqhekeza. Ivalve kufuneka ibekwe ime nkqo, hayi i-flange etywina umphezulu wokudibana nomhlaba, kodwa ingavunyelwa ukuba ihlangane.
Ukuze ugcine i-valve ikwimeko efanelekileyo, ngaphezu kwesidingo sendawo yokugcina i-valve eyomileyo kunye neyomoya, ecocekileyo kunye necocekileyo, kufuneka kubekho isethi yenkqubo yolawulo lwezenzululwazi, yonke into yokugcina ivalve kufuneka igcinwe rhoqo.
Ukusetyenziswa kwexesha elide le-valve, ukuba kusetyenziswe ukupakisha kwe-asbestos, kufuneka kube ukupakisha kwe-asbestos ukusuka kwileta yokupakisha isuswe, ukwenzela ukuba ugweme ukubola kweekhemikhali ze-elektroniki, umonakalo kwisiqu.
Ngaphezulu kwezibonelelo zokusetyenziswa kwe-rust inhibitors, i-lubricants, kufuneka itshintshwe rhoqo okanye yongezwe.
Uthini umgaqo osebenzayo wevalve yebhabhathane?

Ukusebenza kuyafana naleyo ye-aivalve yebhola, evumela ukuvala ngokukhawuleza. Iivalve zebhabhathanezithandwa ngokubanzi kuba zibiza ngaphantsi kolunye uyilo lwevalvu, kwaye zikhaphukhaphu ngoko zidinga inkxaso encinci. I-disc ibekwe embindini wombhobho. Intonga idlula kwidiski iye kwi actuator engaphandle kwevalve. Ukujikeleza i-actuator ijika i-disc ukuba ihambelane okanye i-perpendicular ukuhamba. Ngokungafani ne-valve yebhola, i-disc ihlala ikhona ngaphakathi kokuhamba, ngoko ibangela ukuhla kwengcinezelo, nangona ivulekile.

Ivalve yebhabhathane ivela kusapho lweevalvu ezibizwa ngokuba ziiquarter-turn valves. Ekusebenzeni, i-valve ivuleke ngokupheleleyo okanye ivaliwe xa i-disc ijikeleza ikota. "Ibhabhathane" yidiski yentsimbi efakwe kwintonga. Xa i-valve ivaliwe, i-disc iguqulwa ukuze ivalwe ngokupheleleyo kwipaseji. Xa i-valve ivuleke ngokupheleleyo, i-disc ijikeleziswa kwikota yekota ukwenzela ukuba ivumele ukudlula okungathintelwanga kolwelo. Ivalve isenokuthi ivulwe ngokunyukileyo ukuqukuqela.

Kukho iindidi ngeendidi zeevalvu zebhabhathane, nganye ilungiselelwe iingcinezelo ezahlukeneyo kunye nokusetyenziswa okwahlukileyo. Ivalve yebhabhathane ye-zero-offset, esebenzisa ukuguquguquka kwerabha, inomlinganiselo ophantsi woxinzelelo. I-valve ye-butterfly esebenza kakuhle kabini, esetyenziswa kwiinkqubo zoxinzelelo oluphezulu kancinci, ihlanjululwe ukusuka kumgca ophakathi wesihlalo sediski kunye nokutywinwa komzimba (i-offset enye), kunye nomgca ophakathi webhore (i-offset ezimbini). Oku kudala intshukumo yecam ngexesha lokusebenza ukuphakamisa isihlalo ngaphandle kwetywina okukhokelela ekukhuhlaneni okuncinci kunoko kwenziwa kuyilo lwe-zero offset kunye nokunciphisa utyekelo lwaso lokunxiba. Ivalve ifanelene kakhulu neenkqubo zoxinzelelo oluphezulu yivalve yebhabhathane ephindwe kathathu. Kule valve i-disc seat i-axis yoqhagamshelwano i-offset, eyenza ukuphelisa unxibelelwano lokutyibilika phakathi kwediski kunye nesihlalo. Kwimeko yeevalvu eziphindwe kathathu isihlalo senziwe ngesinyithi ukuze sitshintshwe njengokufikelela kwi-bubble tight shut-off xa udibana nediski.

Kutheni iValve Yam Ivuza?

Iivalvu zinokuvuza ngenxa yezizathu ezahlukeneyo, kubandakanya:

  • Ivalve yiayivalwanga ngokupheleleyo(umzekelo, ngenxa yobumdaka, inkunkuma, okanye omnye umqobo).
  • Ivalve yiyonakele. Ukonakaliswa nokuba sisitulo okanye itywina kunokubangela ukuvuza.
  • Ivalve yiayilungiselelwanga ukuvala 100%. Iivalvu eziyilelwe ulawulo oluchanekileyo ngexesha lokutshiza zisenokungabinawo amandla okuvala/ukucima.
  • Ivalve yileubungakanani obungalungangakwiprojekthi.
Loluphi ulwazi endiludingayo ubungakanani obufanelekileyo kwaye ndikhethe ivalve?
Iziqwenga ezintandathu zolwazi ezisisiseko ziyafuneka ubungakanani kwaye ukhethe ivalvu yokhuseleko okanye yoxinzelelo loxinzelelo:

  1. Ubungakanani boqhagamshelwano kunye nohlobo
  2. Seta uxinzelelo (psig)
  3. Ubushushu
  4. Uxinzelelo lwangasemva
  5. Inkonzo
  6. Umthamo ofunekayo
