3. Ivalve yeBhola
Ivalve yebhola yavela kwivalve yeplagi. Inxalenye yayo yokuvula kunye nokuvala i-sphere, kwaye i-sphere ijikeleza i-90 ° malunga ne-axis ye-valve stem ukufezekisa injongo yokuvula nokuvala. Ivalve yebhola isetyenziswa ikakhulu kwimibhobho ukusika, ukusasaza, kunye nokutshintsha indlela yokuhamba kwe medium. Ivalve yebhola eyilelwe ngokuvuleka okumise okwe-V nayo inomsebenzi wokulawula ukuhamba kakuhle.
Umzi-mveliso wevalvu we-TWS ubonelela ivelufa ehlala ibhabhathane eyomelelayo ehleliyo YD37A1X3-16Q, ivalve yebhabhathane eneflanged ephindwe kabiniD34B1X3-16Q, I-valve ye-butterfly eccentric ephindwe kabini ngokuhambelana ne-Ser.13 okanye i-series 14, BS5163 / F4 / F5 / ANSI CL150 i-rubber ehleliyo i-valve yesango, i-Y-strainer, i-valve yokulinganisa, i-backflow blocker.
3.1 Izinto ezilungileyo:
① Inobuxhakaxhaka bokuqukuqela okusezantsi (okuyi-0).
② Ekubeni ayiyi kubamba ngexesha lokusebenza (ngokungabikho kwe-lubricant), inokusetyenziswa ngokuthembekileyo kwimithombo yeendaba ezonakalisayo kunye nolwelo oluphantsi lokubilisa.
③ Inokufezekisa ukutywinwa okupheleleyo ngaphakathi koxinzelelo olukhulu kunye noluhlu lobushushu.
④ Inokufikelela ngokukhawuleza ukuvulwa kunye nokuvala. Ixesha lokuvula kunye nokuvalwa kwezinye izakhiwo yi-0.05 kuphela kwi-0.1 imizuzwana, ukuqinisekisa ukuba ingasetyenziselwa kwiinkqubo ezizenzekelayo zeebhentshi zokuvavanya. Xa uvula kwaye uvala i-valve ngokukhawuleza, akukho mpembelelo ngexesha lokusebenza.
⑤ Inxalenye yokuvala engqukuva inokuzibeka ngokuzenzekelayo kwindawo yomda.
⑥-- Isiphakathi esisebenzayo sitywinwe ngokuthembekileyo kwivalve.
UMBUZO Ngoko ke, i-medium ejikelezayo kwivalve ngesantya esiphezulu ayiyi kubangela ukhukuliseko lweendawo zokutywina.
⑧ Inesakhiwo esidibeneyo kunye nobunzima obulula. Inokuthi ithathelwe ingqalelo njengeyona ndlela ifanelekileyo ye-valve yenkqubo ye-low-temperature medium.
⑨ Iivalveumzimba u-symmetrical. Ngokukodwa kwisakhiwo somzimba wevalve edityanisiweyo, inokumelana noxinzelelo olusuka kumbhobho.
⑩ Inxalenye yokuvala inokumelana nokwahlukana koxinzelelo oluphezulu ngexesha lokuvala.
⑪ Ivalve yebhola enomzimba wevalve edityaniswe ngokupheleleyo inokungcwatywa ngokuthe ngqo phantsi komhlaba, ikhusela amalungu angaphakathi evalve ekudlekeni. Ubomi bayo obukhulu benkonzo bunokufikelela kwiminyaka engama-30, okwenza kube yeyona valve ifanelekileyo kwimibhobho yeoli kunye negesi yendalo.
3.2 Izinto ezingeloncedo:
① Eyonaivalveisihlalo sekhonkco lokutywina izinto zevalve yebhola yi-polytetrafluoroethylene (PTFE). Ayisebenzi phantse kuzo zonke izinto zekhemikhali kwaye ineempawu ezibanzi ezifana ne-coefficient encinci ye-friction, ukusebenza okuzinzileyo, ukuxhathisa ukuguga, uluhlu olubanzi lobushushu obusebenzayo, kunye nokusebenza okugqwesileyo kokutywinwa. Nangona kunjalo, iipropathi ezibonakalayo ze-PTFE, kubandakanywa i-coefficient ephezulu yokwandisa, uvakalelo lokuhamba okubandayo, kunye nokungahambi kakuhle kwe-thermal, kufuna ukuba uyilo lwesitywina sesihlalo sevalve kufuneka lwenziwe malunga nezi mpawu. Ngoko ke, xa izinto zokutywinwa ziqina, ukuthembeka kwesitywina kuphazamisekile. Ngaphezu koko, ibakala lokumelana nobushushu be-PTFE lisezantsi noko, kwaye linokusetyenziswa kuphela kumaqondo obushushu angaphantsi kwe-180°C. Xa iqondo lokushisa lidlula eli xabiso, izinto zokutywina ziya kuguga. Ukuqwalasela ukusetyenziswa kwexesha elide, ngokuqhelekileyo isetyenziswa kuphela kwi-120 ° C.
② Ulawulo lwayo lumbi kakhulu kunolo lwevalve yeglowubhu, ngakumbi kwiivalvu zepneumatic (okanye iivalvu zombane.
5. I-Valve yokuPlaga
Ivalve yeplagi ibhekisa kwivalve ejikelezayo apho indawo yokuvala ikwimo yeplunger. Ngokujikeleza i-90 °, ukuvuleka kwepaseji kwiplagi kwenziwa ukuba kunxibelelane okanye kuhlulwe kwi-paseji yokuvula kumzimba we-valve, ukufezekisa ukuvula okanye ukuvala i-valve. Ikwabizwa ngokuba yiqhude, istopcock, okanye isango elijikelezayo. Ubume beplagi ingaba yi-cylindrical okanye i-conical. Zininzi iintlobo zayo, kuquka uhlobo oluthe tye, uhlobo lweendlela ezintathu, kunye nodidi lweendlela ezine. Umgaqo wayo ngokusisiseko ufana nevalve yebhola.
5.1 Izinto eziluncedo:
① Ilungele ukusebenza rhoqo, ngokuvula nokuvala okukhawulezayo nokukhanya.
② Ukuxhathisa ulwelo kuncinci.
③ Inesakhiwo esilula, umthamo omncinci, ubunzima obulula, kwaye kulula ukuyigcina.
④ Inokusebenza kakuhle kokutywinwa.
⑤ Akuthintelwa ngumkhombandlela wofakelo, indlela yokuhamba yendlela ephakathi inokuba yinto engafanelekanga.
⑥ Akukho kungcangcazela, kwaye ingxolo iphantsi.
5.2 Izinto ezingeloncedo:
⑦ Umphezulu wokutywina mkhulu kakhulu, okukhokelela kwitorque eninzi kunye nokungaguquguquki okwaneleyo.
⑧ Ichaphazeleka bubunzima bayo, ubungakanani bedayamitha yevalvu bukhawulelwe.
Ekusetyenzisweni kwangempela, ukuba i-valve yobungakanani obukhulu iyadingeka, kufuneka kusetyenziswe isakhiwo seplagi esingasemva, esinokuthi sichaphazele umphumo wokutywinwa.
Iinkcukacha ezithe kratya, unokufumaneka ngokukhululekileyoIvalve ye-TWSumzi-mveliso.
