Ngokwendlela yezinto zokutywina, iivalves zamasango zihlala zahlulwe zaziindidi ezahlukeneyo, ezinje ngevali yesango, isivingco esilinganayo, isivalo esilinganayo sesango, isango lesango elinemigangatho emibini, njl. Iipavali zamasango ezifanayo.
1. Intonga emnyama wedge esangweni ivelufa
Inxalenye yokuvula kunye nokuvala kwevalve yesango elimnyama yipleyiti yesango, indlela yokuhamba kwepleyiti yesango ijonge kwicala lolwelo, ivalve yesango inokuvulwa ngokupheleleyo kwaye ivalwe ngokupheleleyo, ayinakulungelelaniswa kwaye iphoswe . Ipleyiti yesango inezinto ezimbini zokutywina. Ubuso obuncinci bokutywina kwimo yesiqhelo esetyenziswa kwivelufa yentsimbi. I-wedge Angle iyahluka ngeparamitha yeparamitha, ngesiqhelo i-50, kunye ne-2 ° 52 'xa ubushushu obuphakathi bungekho phezulu. Isango levalve yesango le-wedge eveliswe yiZhejiang Star Ou valve inokwenziwa iyonke, ibizwa ngokuba yisango eliqinileyo; Inokwenziwa nakwisango elinokuvelisa ukulandelwa komkhondo ukuphucula itekhnoloji yayo kunye nokwenza ukuphambuka kwendawo yokutywina iAngle kwinkqubo yokuqhubekeka. Eli sango libizwa ngokuba lisango elibhetyebhetye.
2.Ivaluva yesango lokuvala
I-valve yokufaka i-thermal yesango isetyenziswa kakhulu kwi-petroleum, imichiza, isinyithi, amayeza kunye nezinye iinkqubo, ibhatyi yevalve idityaniswe phakathi kweeflanges ezimbini zevalve, icala levalve, emazantsi kubonelelwa ngonxibelelwano lwebhatyi, ibhatyi inokuhamba ngokukhululekileyo ngomphunga okanye enye into eshushu yokugquma ubushushu, ukuqinisekisa ukuba i-viscous medium inokuhamba kakuhle ngevalve.
3. Ivaluva yasesangweni
Indawo yokuvula neyokuvala yevalufa yesango levalufa yidiski ebunjiweyo, umphezulu wokutywinwa ucabalele okanye uyindilinga, kwaye idiski ihamba kumgca othe tye ecaleni komgca wombindi wolwelo. Ifom yokuhamba kwesitina sevalve, kukho uhlobo lokuphakamisa intonga (ukuphakamisa isiqu, isondo elijikeleziselayo aliphakamisi), kukwakho nokuphakamisa uhlobo lwentonga ejikelezayo (ihewheel yesandla kunye nesiqu sevalve ngokudibeneyo kokuphakamisa, nut kumzimba wevalve). Iibheyibhu zeeribhoni ezineribhoni zilungele ukuvulwa ngokupheleleyo kunye nokuvala ngokupheleleyo. Uhlengahlengiso kunye nokuphamba akuvumelekile. Olu hlobo lwevalvu luya kufakwa ngokuthe tyaba kumbhobho.
4. Ivalve yentsimbi engenanto
Insimbi yesango lesango lesinyithi uxinzelelo lwegama: 1.0Mpa, 1.6Mpa, 2.5Mpa; 2, uxinzelelo lovavanyo lweqokobhe: P = 1.5Pn; 3. Tywina uxinzelelo lovavanyo: P = 1.1Pn; 4, uxinzelelo iplagi: PN1.0MPa stainless intsimbi isango vana 0.09 ~ 0.8Mpa, PN1.6Mpa insimbi isango vana vana 0,0 ~ 1.2Mpa, PN2.5Mpa steel stainless esangweni vana vana 0.15 ~ 1.6Mpa; 5. Isixhobo esisetyenziswayo: amanzi; 6.ubushushu olusebenzayo: 0 ℃ ~ 180 ℃.
5. Elastic isihlalo itywina valve
6. Ivaluva yesango lemela
Inxalenye yokuvula kunye neyokuvala yevalve yesango lesango yipleyiti yesango, indlela eshukuma ngayo ipleyiti yesango ijongise kwicala lolwelo, i-valve yemela yesango inokuvulwa ngokupheleleyo kwaye ivalwe ngokupheleleyo, ayinakulungiswa kwaye ukhubekile. Ipleyiti yesango inezinto ezimbini zokutywina. Ubuso obuncinci bokutywina kwimo yesiqhelo esetyenziswa kwivelufa yentsimbi. I-wedge Angle iyahluka ngeparamitha yeparamitha, edla ngokuba ngama-50. Kananjalo inokwenza ukuba ivelise umkhondo wokumila kwenkunzi yegusha, ukwenzela ukuphucula ukuveliswa kwayo, yenzele umphezulu wokutywina kwi-Angle kwinkqubo yokuphambuka kwethu, isango ebizwa ngokuba yi-elastic disc uhlobo lwevalve yesango ivaliwe, ukutywina umphezulu kunokuxhomekeka kuphela kuxinzelelo oluphakathi lokutywina, oluxhomekeke kuxinzelelo oluphakathi, idiski iya kuba kwelinye icala lesitulo sokutywina uxinzelelo lomphezulu wokuqinisekisa ukuba itywina lobuso ... I-Zhejiang inkwenkwezi okanye uhlobo lwesitshi sesango yivelufa yemveliso isebenzisa ukutywina okunyanzelekileyo, ivalve ivaliwe, ukuxhomekeka kumandla angaphandle anyanzelise uxinzelelo lwenkunzi yegusha esihlalweni, ukuqinisekisa umphezulu wokutywina lolu hlobo lokutywinwa kwevalvethi kuya kufakwa ngokubanzi Umbhobho.
7. Ivelufa yesango lobushushu eliphantsi
Inxalenye yokuvula kunye neyokuvala yevalve yesango lobushushu obuphantsi yipleyiti yesango, ulwalathiso lwentsimbi yesipleyiti yesango lujolise kwicala lolwelo, isivingco sesango sinokuvuleka ngokupheleleyo kwaye sivalwe ngokupheleleyo, ingekuko ukumiselwa nokunyanzelwa. Ipleyiti yesango inezinto ezimbini zokutywina. Ubuso obuncinci bokutywina kwimo yesiqhelo esetyenziswa kwivelufa yentsimbi. I-wedge Angle iyahluka ngeparamitha yeparamitha, ngesiqhelo i-50, kunye ne-2 ° 52 'xa ubushushu obuphakathi bungekho phezulu. Isango levalve yesango le-wedge lingenziwa liphelele, elibizwa ngokuba lisango eliqinileyo; Inokwenziwa nakwisango elinokuvelisa ukulandelwa komkhondo ukuphucula itekhnoloji yayo kunye nokwenza ukuphambuka kwendawo yokutywina iAngle kwinkqubo yokuqhubekeka. Eli sango libizwa ngokuba lisango elibhetyebhetye.
8. Flanged manual esangweni ivelufa
Flanged esangweni ivelufa yi esisangqa imo isango vana uxhulumaniso imo, le imo uqhagamshelo iqhelekile. Ivalufa yesango esisangqa izinzile kwaye ithembekile xa isetyenziswa kumbhobho, ke akulunganga ukusebenzisa ivalve yesango yevalufa yombhobho woxinzelelo oluphezulu.
9. Yangcwatywa ivelufa yesango
10. Vula ivali yesiqu se-wedge
Uhlobo lwevalve yesango, ngokokumiselwa komhlaba kokutywinwa kunokwahlulwa lube luhlobo lwegeveji yesango kunye nevelufa yesango elingqinelanayo, uhlobo lwevalve yohlobo lwesango inokuhlulwa lube: uhlobo lwesango elinye, uhlobo lwesango eliphindwe kabini kunye nohlobo lwesango oluguquguqukayo; Iipavalve ezifanayo zamasango zingahlulwa zibe yinye kunye nesango eliphindwe kabini. Ngokutsho indawo Screw esiqwini, oko lungohlulwa lube isiqu eqaqambileyo ivelufa esangweni kunye ivelufa isiqu emnyama. Xa ivalve yesango lokuvala ivaliwe, indawo yokutywina inokutywinwa kuphela ngoxinzelelo oluphakathi, oko kukuthi, umphezulu wokutywina wesango ucinezelwe kwelinye icala lesihlalo sevalve ukuqinisekisa umphezulu wokutywina, ozitywinayo . Uninzi lwezivalo zesango linyanzeliswa ukuba litywinwe, oko kukuthi, xa ivalve ivaliwe, kunyanzelekile ukuba ixhomekeke kumandla angaphandle ukunyanzela isango kwisihlalo sevalve ukuqinisekisa indawo yokutywina.
Isamente yentsimbi yesango ivelufa ngentambo yangaphakathi
Indawo yokuvula neyokuvala yentsimbi yangaphakathi yesango yiplagi emile okwe-disc, umphezulu wokutywinwa ucabalele okanye uyindilinga, kwaye idiski ihamba kumgca othe tye ecaleni komgca wombindi wolwelo. Ifom yokuhamba kwesitina sevalve, kukho uhlobo lokuphakamisa intonga (ukuphakamisa isiqu, isondo elijikeleziselayo aliphakamisi), kukwakho nokuphakamisa uhlobo lwentonga ejikelezayo (ihewheel yesandla kunye nesiqu sevalve ngokudibeneyo kokuphakamisa, nut kumzimba wevalve). Iibheyibhu zeeribhoni ezineribhoni zilungele ukuvulwa ngokupheleleyo kunye nokuvala ngokupheleleyo. Uhlengahlengiso kunye nokuphamba akuvumelekile.
11.Ivalufa yesango elisicaba
Isivingco esithe tyaba yivelufa esisilayidi enento yokuvala isango elinganayo. Ilungu lokuvala linokuba sisango elinye okanye isango eliphindwe kabini elinendlela yokurhoxa phakathi kwabo. Uxinzelelo lwesango esihlalweni lulawulwa luxinzelelo oluphakathi olusebenza kwisango lokudada okanye isihlalo esidadayo. Kwimeko yevalufa yediski ephindwe kabini yesango, indlela yokubuyela umva ebonwe kumasango amabini inokuncedisa kolu xinzelelo.
12. I-disc ephindwe kabini yesango lesango lesinyithi
Idiskhi idiskhi waphosa intsimbi kwezivalo ezisetyenziswa ngokubanzi petroleum, imichiza, amayeza, amandla ombane kunye namanye amashishini. Kuxinzelelo lwegama ≤ L, 0MPa umphunga, amanzi, ioyile kunye neminye imibhobho yemithombo yeendaba, esetyenziselwa ukuvula nokuvala.
