I-valve yokunciphisa ukucindezela ibhekisela ku-valve eyehlisa ukucindezela kokungena kungcindezi yokuphuma edingekayo ngokusebenzisa i-throttling ye-valve disc, futhi ingasebenzisa amandla we-medium ngokwayo ukugcina ukucindezela kokuphumayo kungashintshile lapho ukucindezela kokungena nokugeleza kushintsha.
Ngokuya ngohlobo lwe-valve, ukucindezela kokuphuma kunqunywa ukumiswa kokulawulwa kwengcindezi ku-valve noma inzwa yangaphandle. Ama-valve okunciphisa ingcindezi avame ukusetshenziswa ezindaweni zokuhlala, ezentengiselwano, ezikhungweni nasezimbonini.
Izidingo zokuhlolwa kwekhwalithi yokunciphisa ukucindezela kokubonakala kwe-valve
Ukuhlolwa kwekhwalithi ye-valve yokunciphisa ingcindezi
I-valve yokunciphisa ukucindezela akumele ibe namaphutha njengokuqhekeka, ukuvala okubandayo, amabhamuza, ama-pores, izimbobo ze-slag, i-shrinkage porosity kanye ne-oxidation slag inclusions. Ukuhlolwa kwekhwalithi yendawo yevalvu ikakhulukazi kuhlanganisa nokuhlolwa kokucwebezela kwendawo, ukucaba, ama-burrs, imihuzuko, ungqimba lwe-oxide, njll. Kudingeka kwenziwe endaweni ekhanyiswe kahle futhi kusetshenziswa.
amathuluzi okuhlola indawo ochwepheshe.
Indawo engeyona yomshini ye-valve yokunciphisa ingcindezi kufanele ibe bushelelezi futhi isicaba, futhi uphawu lokuphonsa kufanele lucace. Ngemuva kokuhlanza, ukuthululela kanye nesikhuphukeli kufanele kushaywe ngobuso be-casting.
Usayizi we-valve yokunciphisa ingcindezi nokuhlolwa kwesisindo
Ubukhulu be-valve bunomthelela oqondile ekusebenzeni kokuvula nokuvala kwe-valve nokusebenza kokuvala. Ngakho-ke, ngesikhathi sokuhlolwa kokubukeka kwe-valve, ubukhulu be-valve budinga ukuhlolwa ngokuqinile. Ukuhlolwa kobukhulu ikakhulukazi kuhlanganisa ukuhlolwa kobubanzi be-valve, ubude, ubude, ububanzi, njll. Usayizi nokuchezuka kwesisindo sevalvu yokunciphisa ingcindezi kufanele kuhambisane nemithetho noma ngokuya ngemidwebo noma amamodeli ahlinzekwe umthengi.
Ukuhlolwa kokumaka i-valve yokunciphisa ingcindezi
Ukuhlolwa kokubukeka kwevalvu yokunciphisa umfutho kudinga ukuhlolwa kwelogo yevalvu, okumele kuhlangabezane nezidingo zezindinganiso zomkhiqizo wevalvu. Ilogo kumele icace futhi kungabi lula ukuwa. Hlola ilogo yevalve yokunciphisa ukucindezela. Umzimba wevalvu kufanele ube nempahla yomzimba yevalvu, ingcindezi encane, usayizi ojwayelekile, inombolo yesithando somlilo esincibilikayo, isiqondiso sokugeleza, kanye nophawu lokuhweba; i-nameplate kufanele ibe nemidiya esebenzayo, i-inlet pressure range, i-outlet pressure range, kanye negama lomkhiqizi. Ukucaciswa kwemodeli, usuku lokukhiqiza.
Ukuhlolwa kokupakishwa kwebhokisi lombala webhokisi le-valve yokunciphisa ingcindezi
Ama-valve okunciphisa ingcindezi adinga ukupakishwa ngaphambi kokushiya imboni ukuze avikele ama-valve ekulimaleni ngesikhathi sokuthutha nokugcinwa. Ukuhlolwa kokubukeka kwe-valve yokunciphisa ukucindezela kudinga ukuhlolwa kwelebula yebhokisi le-valve kanye nokupakishwa kwebhokisi lombala.
Izidingo zokuhlola ukusebenza kwe-valve enciphisa ingcindezi
Ingcindezi yokwehlisa umfutho we-valve elawula ukuhlolwa kokusebenza
Ngaphakathi kwebanga elinikeziwe lokulawula ingcindezi, ingcindezi yokuphumayo kufanele ihlale ilungiswa phakathi kwevelu ephezulu kanye nenani eliphansi, futhi akumele kube khona ukuvinjelwa noma ukudlidliza okungavamile.
Ukuhlolwa kwezimpawu zokugeleza kwe-valve yokunciphisa ingcindezi
Lapho ukugeleza kwe-outlet kushintsha, i-valve yokunciphisa ingcindezi akumele ibe nezenzo ezingavamile, kanye nenani elingalungile lokuphambuka kokucindezela kwayo okuphumayo: kuma-valve okunciphisa ukucindezela okuqondile, akumele kube ngaphezu kuka-20% wengcindezi yokuphuma; kuma-valve okunciphisa ingcindezi eqhutshwa ngumshayeli, akumele ibe mkhulu kuno-10% wokucindezela kokuphumayo.
Ukuhlolwa kwezimpawu zokucindezela kwe-valve yokunciphisa ingcindezi
Lapho umfutho we-inlet ushintsha, i-valve yokunciphisa ingcindezi akufanele ibe nokudlidliza okungavamile. Ivelu yokuchezuka komfutho we-outlet: kuma-valve okunciphisa ingcindezi esebenza ngokuqondile, akumele ibe mkhulu kuno-10% wengcindezi yokuphuma; kuma-valve okunciphisa ingcindezi eqhutshwa ngumshayeli, akumele ibe mkhulu kuno-5% wengcindezi yokuphuma.
| Usayizi womsebenzi DN | Ubukhulu bokwehla kwevolumu yokuvuza (amabhamuza)/min |
| ≤50 | 5 |
| 65 ~ 125 | 12 |
| ≥150 | 20 |
Uphawu olunwebekayo olukhuphukayo lwegeyiji yokucindezela kokuphumayo kufanele kube insimbi enguziro - uphawu lwensimbi akufanele ludlule u-0.2MPa/min.
ikhono lokusebenza okuqhubekayo
Ngemuva kokuhlolwa kokusebenza okuqhubekayo, isengahlangabezana nokusebenza kokulawula ingcindezi kanye nezidingo zokugeleza.
