Kwiinkqubo zemibhobho yemizi-mveliso,Iivalvu zeBholaZisetyenziswa kakhulu njengezixhobo ezithembekileyo zokuvala ngenxa yesakhiwo sazo esilula, ukusebenza ngokukhawuleza, kunye nokusebenza kakuhle kokuvala. Nokuba kwioyile negesi, ekucutshungulweni kweekhemikhali, ekulungisweni kwamanzi, okanye ekuvelisweni ngokubanzi, iivalvu zebhola zidlala indima ebalulekileyo ekulawuleni ukuhamba kolwelo ngokukhuselekileyo nangokufanelekileyo.
Eli nqaku linika ingcaciso ecacileyo nesebenzisekayo malunga nokuba yintoni ivalvu yebhola, indlela esebenza ngayo, izinto eziphambili zayo, iintlobo, iingenelo, kunye nendlela yokukhetha ivalvu yebhola efanelekileyo kwisicelo sakho esithile.
Yintoni iValve yeBhola
Ivalvu yebhola yivalvu ejika ngekota elawula ukuhamba kolwelo ngokujikeleza ibhola engqukuva enebhore embindini wayo. Xa ibhore ihambelana nombhobho, ivalvu ivulekile; xa ijikeleziswa ngama-90 degrees, inxalenye eqinileyo yebhola ivala ukuhamba kwayo ngokupheleleyo.
Xa kuthelekiswa nezinye iintlobo zeevalvu, iivalvu zebhola zaziwa kakhulu ngokukwazi kwazo ukuvala ngokuqinileyo, ukwehla okuncinci koxinzelelo, kunye nokusebenza ngokukhawuleza kokuvula nokuvala, nto leyo eyenza ukuba zifaneleke ngakumbi kwizicelo ezifuna ukuhlukaniswa rhoqo okanye okungxamisekileyo.
Izinto eziphambili zeValve yeBhola
Nangona uyilo lunokwahluka, uninzi lweevalvu zebhola zemizi-mveliso ziquka ezi zinto zilandelayo ziphambili:
1. Umzimba weValve
Iumzimba wevalvuliqokobhe langaphandle levalvu yebhola, elisetyenziselwa ukufaka ezinye izinto kunye nokudibanisa imibhobho. Ngokwesiqhelo lenziwe ngezinto ezifana nentsimbi ephosiweyo, intsimbi eqingqiweyo okanye intsimbi engatyiwayo ukuze ivumelane neendawo ezahlukeneyo zokusebenza kunye nemidiya.
2. Ibhola yeValve
Iibholayinxalenye ephambili yevalvu yebhola, idla ngokuba yisakhiwo esingqukuva esinomngxuma ojikelezayo. Ngokujikelezisa ibhola, ukuhamba kolwelo kungatshintshwa okanye icala lokuhamba kwalo lingatshintshwa. Ibhola yahlulwe yaba ziintlobo ezimbini:
Ibhola edadayo: Ibhola ayinayo i-shaft yokuxhasa kwaye icinezelwa ngokuqinileyo kumphezulu wokuvala wesiphelo se-outlet ngoxinzelelo oluphakathi. Ifanelekile kwiimeko zoxinzelelo oluphakathi noluphantsi.
Ibhola efakwe kwiTrunnion: Ibhola iqhagamshelwe ngokuqinileyo kwiziqu zevalvu eziphezulu nezisezantsi, ifanelekile kwiimeko zoxinzelelo oluphezulu kunye nobubanzi obukhulu, kwaye ukusebenza kokutywina kuzinzile ngakumbi.
3. Isihlalo seValve
Isihlalo sevalvu yinxalenye yokutywina phakathi kwebhola kunye nomzimba wevalvu, ngokuqhelekileyo yenziwe ngerabha okanye izinto zesinyithi. Kwiivalvu zebhola ezidadayo, isihlalo sevalvu sithwala uxinzelelo lwebhola; kwiivalvu zebhola ezizinzileyo, isihlalo sevalvu singena ngokuqinileyo nebhola ngamandla entwasahlobo kunye namandla aphakathi ukuqinisekisa ukutywina.
4. Isiqu sevalvu
Isiqu sevalvu sidibanisa umqhubi (njengesiphatho, izixhobo zempethu okanye isixhobo sombane) kunye nebhola ukuze kudluliselwe amandla okujikeleza. Isiqu sevalvu sidla ngokuyilwa njengesakhiwo esingavuziyo ukuqinisekisa ukuthembeka kwevalvu phantsi koxinzelelo oluphezulu.
5. Ukusebenza
Umqhubi usetyenziselwa ukuqhuba isiqu sevalvu ukuze sijikeleze ibhola. Iindidi eziqhelekileyo ziquka i-manual, i-pneumatic actuator, i-electric actuator kunye nezixhobo ze-hydraulic. Ubungakanani, uxinzelelo kunye nobuninzi bokusebenza kwevalvu kufuneka kuqwalaselwe xa kukhethwa umqhubi.
6. Ukupakisha
Ukupakisha kusetyenziselwa ukuvala umsantsa phakathi kwesiqu sevalvu kunye nomzimba wevalvu ukuthintela ukuvuza okuphakathi. Izinto eziqhelekileyo ziquka i-graphite, i-polytetrafluoroethylene, njl.njl., ezinokumelana nokugqwala okuhle kunye nokusebenza kakuhle kokuvala.
7. Ezinye izakhiwo ezincedisayo
Ezinye iivalvu zebhola zikwaxhotyiswe ngezakhiwo ezincedisayo ezifana neejakethi zokukhusela okanye izitywini zeoyile ukuze zilungele iimeko zokusebenza ezikhethekileyo (ezifana nobushushu obuphezulu, uxinzelelo oluphezulu okanye i-easy crystallization medium).
Isebenza njani iValve yeBhola
Iivalvu zebhola zisebenza ngendlela elula yokujika ikota. Ukujikeleza isiphatho okanye i-actuator ngama-90 degrees kujika ibhola ngaphakathi komzimba wevalvu. Xa imbobo yebhola ihambelana nombhobho, ulwelo luhamba ngokukhululekileyo. Xa ijikeleziswa ngokuthe nkqo kwicala lokuhamba, ibhola ivala ngokupheleleyo indlela.
Lo mgaqo wokusebenza ulula unciphisa ukuguguleka, unciphisa i-torque yokusebenza, kwaye uvumela impendulo ekhawulezileyo kwiimeko ezinzima zokuvala.
