Inkcazo eneenkcukacha ngendlela echanekileyo yokuqhuba ivalve

Ukulungiselela ngaphambi kokusebenza

Ngaphambi kokuba isebenze ivalve, kufuneka ufunde imiyalelo yokusebenza ngononophelo. Ngaphambi kokusebenza, kuya kufuneka ucace malunga nendlela yokuhamba kwegesi, kuya kufuneka unikele ingqalelo ukukhangela ukuvulwa kwe-valve kunye neempawu zokuvala. Jonga ukubonakala kwevali ukuze ubone ukuba iva iva iva ivutha, ukuba kukho umswakama owomileyo; Ukuba ufumanise ukuba ezinye iingxaki eziza kujongwana nangexesha, aziyi kusebenza ngokusilela. Ukuba ivalve yombane ingaphandle kwenkonzo ngaphezulu kweenyanga ezintathu, i-clutch kufuneka ihlolwe ngaphambi kokuqala, qiniseka ukuba isiphatho sikwisikhundla sencwadi, kwaye emva koko siqwalasele i-wiring yombane kwimoto.

Ukusebenza ngokufanelekileyo kweeplanga

I-valves ze-valves zezona vallo zisetyenziswa kakhulu, kwaye iisiphatho zawo okanye iisingari zenziwe ngokuhambelana namandla aqhelekileyo omntu, kuthathelwa ingqalelo amandla omhlaba wokutywina kunye namandla afunekayo. Ke ngoko, awunakusebenzisa i-lever ende okanye isandla eside ukuhambisa ipleyiti. Abanye abantu baqhele ukusetyenziswa kwesandla seplate, kufuneka banikele ingqalelo engqongqo kwi-valve kufuneka basetyenziselwe ukunyanzela ukuba banyanzelwe ukuba banyanzelise ukuvulwa, oko kukuthintelwa ivalve, amandla kufuneka ifuthe, hayi impembelelo. Ukuvulwa kwempembelelo kunye nokuvalwa kwamacandelo evali-phumela kakhulu kuthathelwa ingqalelo le mpembelelo kunye nee-valves ngokubanzi akunakulingana neqela lemigulukudu.

Xa ivalve ivulekile ngokupheleleyo, isifo sethumbe kufuneka siphindwe kancinane, ukuze imisoni phakathi kwe-stit, ukuze ingawukhululi umonakalo. KubaI-valves yesango,Ukukhumbula ukuvula ngokupheleleyo kwaye kuvalwe ngokupheleleyo xa isikhundla se-STAT, ukunqanda ukuvula ngokupheleleyo xa ifuthe kwiziko elifileyo. Kwaye kulula ukujonga ukuba yinto eqhelekileyo xa ivaliwe. Ukuba i-ofisi ye-valve icinyiwe, okanye i-spool thuls efakwe phakathi kwenkunkuma enkulu, indawo evaliweyo ye-STE evaliweyo kufuneka itshintshwe. Umonakalo kwi-valve yokutywina okanye i-valve ngesandla.

Isibonakaliso seValve Phote: I-Palve yeBhola,ivalve yebhabhathane, i-plug valve stemps ephezulu ye-Groove ehambelana nejelo, ebonisa ukuba ivalve kwisikhundla esivulekileyo; Xa i-valve stemp ijikeleze i-90 ° ukuya ngasekhohlo okanye ngasekunene, iGroove isebenza kwijelo, ebonisa ukuba ivalve kwindawo evalekileyo. Ezinye iivali zebhola, iivali zebhabhathane, i-phunga ukuya kwi-Wrench kunye ne-Chanenel pharallel yokuvula, ezithe nkqo ukuba zivaliwe. Iindlela ezintathu, ii-valves ezine kufuneka zisetyenziswe ngokungqinelana nokumakishwa kokuvulwa, ukuvala nokubuyela umva. Emva kokugqitywa kwemali, isiphatho esishukumayo kufuneka sisuswe.

Ukusebenza ngokuchanekileyo kweevali zokujonga

Ukwenzela ukuthintela amandla aphezulu efuthe enziwe ngalo mzuzu wokuvala iI-rabber yokujonga i-vawve, ivalve kufuneka ivaliwe ngokukhawuleza, oko kuthintele ukwakhiwa kwendawo enkulu yokubuyela umva, ongunobangela woxinzelelo lwempembelelo olwenziwe xa ivalve ivaliwe ngequbuliso. Ke ngoko, isantya sokuvala ivalve kufuneka sihambelane ngokuchanekileyo ngenqanaba lokulola kwendawo esihlala kuyo.

Ukuba i-velocity yendawo yokuhamba iyahluka kakhulu kuluhlu olubanzi, ubuncinci bendawo yokuhamba ayonelanga ukunyanzela into yokuvala ukuya kwindawo ethe tyaba. Kule meko, intshukumo yenqaku lokuvala linokuphuthiswa ngaphakathi koluhlu oluthile lokubetha kwalo. Intshukumo ekhawulezayo yento yokuvala inokubangela ukuba iindawo ezihambayo zevali zinxibe ngokukhawuleza, kukhokelela ekungaphumlweni kwebhotile ngaphambi kwexesha. Ukuba i-Medium iyatsala, ukuntywila ngokukhawuleza kwenqaku lokuvala kukwabangelwa kukuphazamiseka okugqithisileyo. Naphi na apho kunjalo, i-valves kufuneka ibekwe apho kuphazamiseka khona okuphazamisekileyo.
