Ezinhlelweni zokulawula uketshezi lapho ukuphepha, ukuthembeka, kanye nokusabela okusheshayo kubalulekile, ivalvu yokuvala okusheshayo ivelele njengengxenye ebalulekile. Kungakhathaliseki ukuthi ifakwe emapayipini olwandle, ezitshalweni zezimboni, ezinhlelweni zokudlulisa uphethiloli, noma ezindaweni zokuvala eziphuthumayo, lolu hlobo lwevalvu ludlala indima ebalulekile ekuvimbeleni izingozi, ekunciphiseni ukulahleka koketshezi, kanye nokuvikela kokubili imishini kanye nabasebenzi. Ukukhetha ivalvu yokuvala okusheshayo efanele kudinga okungaphezu kokwazi imininingwane eyisisekelo; kuhilela ukuqonda ukuthi imiklamo ehlukene, izinto zokwakha, kanye nezindlela zokusebenza zixhumana kanjani nezimo zokusebenza zangempela.
Ukuqonda Umsebenzi Wevalvu Yokuvala Okusheshayo
A i-valve yokuvala esheshayoyakhelwe ukuvala ukugeleza koketshezi ngokushesha, ngokuvamile ngaphakathi kwengxenye encane yomzuzwana. Lesi sici sibalulekile ezimweni ezifana nokuvuza kukaphethiloli, ukwehla kwengcindezi ngokuzumayo, noma izimo eziphuthumayo zomlilo. Kuye ngomklamo wesistimu, la ma-valve angase aqaliswe ngesandla, asebenze ngomshini, asebenze ngomoya, noma axhunywe ohlelweni lokuvala oluzenzakalelayo oluphuthumayo.
Imisebenzi yabo eyinhloko ihlanganisa:
-
①Ukuvimbela ukuphuma koketshezi noma igesi okuyingozi
-
②Ukunciphisa isikhathi sokungasebenzi ngemva kwesimo esiphuthumayo
-
③Ukuvikela imishini engezansi komfula
-
④Ukuthuthukisa ukuphepha kanye nokuthobela imithetho yesistimu iyonke
Ngenxa yokuthi la ma-valve avame ukusebenza ngaphansi kwezimo ezidinga umzamo omkhulu, inqubo yokukhetha kumele ibhekele ukuthembeka kokusebenza ngaphansi kokucindezeleka.
Izinto Ezibalulekile Okufanele Uzicabangele Lapho Ukhetha I-Valve Yokuvala Ngokushesha
1. Indawo Yokusebenzisa
Izimboni ezahlukene ziveza izindawo zokusebenza ezihluke kakhulu. Isibonelo, indawo yasolwandle idinga ukumelana nokugqwala okuphezulu; uhlelo lukawoyela negesi ludinga isitifiketi esiphephile emlilweni; ukucubungula amakhemikhali kungadinga ukuhambisana nemidiya egqwalisayo noma eshisa kakhulu.
Cabanga ngalokhu:
-
①Imikhakha yezolwandle uma iqhathaniswa neyezimboni uma iqhathaniswa neyamandla
-
②Ukufakwa ngaphakathi noma ngaphandle
-
③Ukuchayeka emanzini anosawoti, umswakama, ukudlidliza, noma amazinga okushisa aphezulu kakhulu
-
④Ukuhambisana nezindinganiso ezithile zomkhakha (isb.,I-DNV, I-ABS, I-API)
2. Uhlobo Lwemidiya kanye Nezipharamitha Zokusebenza
Izici zoketshezi zinquma ingxenye enkulu yokucushwa kwevalvu.
Amapharamitha abalulekile afaka:Uketshezi, igesi, noma umusi.Isilinganiso sokucindezela (PN16, PN25, PN40, njll.).Tububanzi be-emperature.Ukuqina kanye nobuningi.Izidingo zemidiya evuthayo noma enobuthi.
Ukukhetha ivalvu ehambisana nemidiya kuqinisekisa ukusebenza kahle kokushintsha okuzinzile kanye nokuphila isikhathi eside kwenkonzo.
3. Indlela Yokusebenza
Ama-valve okuvala okusheshayo atholakala ngezinhlobo eziningi zokusebenzisa, futhi ukukhetha okufanele kuncike ezidingweni zokuphendula kwesistimu.
Izindlela ezivamile:
-
①Ukudonsa ukuze kuvalwe ngesandla: Ithembekile futhi ilula; ilungele izinhlelo ezincane
-
②I-lever yomshini noma indlela yokulinganisa isisindo: Ukuvala okusheshayo uma kuqalwa
-
③Ukusebenza komoya: Kufanelekela izinhlelo zokulawula ezihlanganisiwe kanye nokuvalwa okuphuthumayo (ESD)
-
④Ukusebenza kwe-Hydraulic: Izinzile ngaphansi kwengcindezi ephezulu
-
⑤Isiqalisi se-electromagnetic / solenoid: Ukuhlanganiswa nezinhlelo zokwenza izinto ngokuzenzakalela kanye nokuthola umlilo
Ezinhlelweni ezibalulekile zokuphepha, ukuphindaphinda—njengokuhlanganisa ukusebenza komoya nokuguqulwa kwesandla—kungadingeka.
4. Izinto Zomzimba Wevalvu
Ukukhethwa kwezinto ezibonakalayo kuthinta ngqo ukuqina nokuhambisana.
Izinto ezivamile zama-valve okuvala okusheshayo zifaka:
-
①Insimbi ephothiweyo / insimbi engagqwaliukusetshenziswa kwezimboni noma olwandle
-
②Ithusi/ithusikwezinhlelo zamanzi olwandle
-
③Insimbi engagqwali ye-Duplexezindaweni ezingcolisa kakhulu
-
④Izinto eziqinisekisiwe ezingashisi umlilokwezinhlelo zikaphethiloli
Ukugqwala, ukuguguleka, kanye nokumelana nokushisa konke kumele kuhlolwe ngokucophelela.
5. Isivinini Sokuvala Nokuzinza
Isici esibaluleke kakhulu—isivinini sokuvala—kumele sihambisane nezidingo zesistimu ngaphandle kokubangela ukushaqeka kwengcindezi noma isando samanzi.
Ivalvu eklanywe kahle inikeza:
-
①Ukuvalwa okusheshayo ngaphansi kwezimo eziphuthumayo
-
②Ukunyakaza okulawulwayo ukuze kugwenywe ukudlidliza kwamapayipi
-
③Ukusebenza okuzinzile kwesikhathi eside ngisho noma kusebenze njalo
Imiklamo ethuthukisiwe ihlanganisa izindlela zokunciphisa umthelela epayipini.
6. Isitifiketi Nokuthobela Imithetho
Ezimbonini ezifana nezasolwandle, uwoyela negesi, kanye nokucubungula amakhemikhali, izitifiketi zibalulekile.
Funa i:
-
①DNV, ABS, BV, LR(ukuhlukaniswa kwezindawo zasolwandle)
-
②CEukuthobela imithetho yaseYurophu
-
③ISO 9001, ISO 14001(ikhwalithi kanye nezinhlelo zemvelo)
-
④Izitifiketi ze-API 607 / Eziphephile Emlilweni
Ukuthobela imithetho kuqinisekisa ukuthi i-valve ihlangabezana nezidingo zokuphepha ezijwayelekile embonini.
7. Izidingo Zokulungisa
Amavalvu okuvala okusheshayo kumele asebenze kahle ngisho nangemva kwesikhathi eside ngaphandle kokusebenza. Ngakho-ke, kulula ukuhlola nokulungisa.
Cabanga ngalokhu:Ukufinyeleleka kwezingxenye ze-actuator.Izidingo zokugcoba.Ukutholakala kwezingxenye ezizofakwa esikhundleni sazo.Ukuthi ivalvu ingahlolwa yini ngaphandle kokuphazamisa ukusebenza kwesistimu
Umklamo wokulungisa ophansi unciphisa izindleko zokusebenza zesikhathi eside.
Kungani Ukukhetha Okufanele Kubalulekile
Ivalvu yokuvala esheshayo ekhethwe ngokungafanele ingaholela emiphumeleni emibi kakhulu—ukuvalwa okulibazisekile, umonakalo womshini, kanye nengozi eyengeziwe yokuvuza noma umlilo. Ngakolunye uhlangothi, ivalvu ekhethwe kahle:
-
①Kuthuthukisa ukuphepha kokusebenza
-
②Kuthuthukisa ukusebenza kahle kwempendulo ephuthumayo
-
③Yehlisa isikhathi sokuphumula esingahleliwe
-
④Isekela ukuthobela imithetho yamazwe ngamazwe
-
⑤Iletha ukonga kwezindleko zesikhathi eside
