Lo matshini uphela yeyona yunithi isisisekoivalvuindibano, kwaye iindawo ezininzi zenza iindawo zevalvu (ezifana nebhonethi yevalvu, idiski yevalvu, njl.njl.). Inkqubo yokuhlanganisa iindawo ezininzi ibizwa ngokuba yindibano yecandelo, kwaye inkqubo yokuhlanganisa iindawo ezininzi kunye neendawo ibizwa ngokuba yindibano iyonke. Umsebenzi wokuhlanganisa unempembelelo enkulu kumgangatho wemveliso. Nokuba uyilo luchanekile kwaye iindawo zifanelekile, ukuba indibano ayifanelekanga, ivalvu ayizukuhlangabezana neemfuno zemigaqo, kwaye ide ikhokelele ekuvuthweni kwetywina.
Kukho iindlela ezintathu eziqhelekileyo zokuhlanganisa iivalvu, ezizezi, indlela yokutshintshana epheleleyo, indlela yokutshintshana okulinganiselweyo, indlela yokulungisa.
Indlela epheleleyo yokutshintshana
Xa ivalvu idityaniswe ngendlela epheleleyo yokutshintshana, inxalenye nganye yevalvu inokuhlanganiswa ngaphandle kokulungiswa nokukhethwa, kwaye imveliso inokuhlangabezana neemfuno zobugcisa ezichaziweyo emva kokuhlanganiswa. Ngeli xesha, iindawo zevalvu kufuneka zicutshungulwe ngokuhambelana ngokupheleleyo neemfuno zoyilo ukuze kuhlangatyezwane neemfuno zokuchaneka kobukhulu kunye nokunyamezelana kwejometri. Iingenelo zendlela epheleleyo yokutshintshana zezi: umsebenzi wokuhlanganisa ulula kwaye uyabiza, umsebenzi awudingi buchule buphezulu, ukusebenza kakuhle kwenkqubo yokuhlanganisa kuphezulu, kwaye kulula ukuhlela umgca wokuhlanganisa kunye nemveliso yobungcali. Nangona kunjalo, xa kwamkelwa indibano epheleleyo yokutshintshana, ukuchaneka komatshini weendawo kufuneka kube phezulu. Ifanelekile kwivalvu yeglobe, ivalvu yokujonga, ivalvu yebhola kunye nezinye iivalvu ezinesakhiwo esilula kunye nobubanzi obuncinci nobuphakathi.
Indlela yokutshintshana elinganiselweyo
Ivalvu idityaniswe ngendlela yokutshintshana okulinganiselweyo, kwaye umatshini wonke unokucutshungulwa ngokwendlela echanekileyo yezoqoqosho. Xa kuhlanganiswa, ubungakanani obuthile obunokulungiswa kunye nesiphumo sembuyekezo bunokukhethwa ukuze kufezekiswe ukuchaneka kwendibano okuchaziweyo. Umgaqo wendlela yokukhetha uyafana nowendlela yokulungisa, kodwa indlela yokutshintsha ubungakanani bendandatho yembuyekezo yahlukile. Eyokuqala kukutshintsha ubungakanani bendandatho yembuyekezo ngokukhetha izixhobo, ngelixa eyesibini kukutshintsha ubungakanani bendandatho yembuyekezo ngokusika izixhobo. Umzekelo: isiseko esiphezulu kunye negasket yokulungisa yevalvu yohlobo lwe-valve yokulawula i-double ram wedge gate valve, i-gasket yokulungisa phakathi kwemizimba emibini yevalvu yebhola ehlukanisiweyo, njl.njl., kukukhetha iindawo ezikhethekileyo njengeendawo zembuyekezo kwikhonkco lobukhulu obunxulumene nokuchaneka kwendibano, kunye nokufezekisa ukuchaneka kwendibano okufunekayo ngokulungisa ubukhulu begasket. Ukuze kuqinisekiswe ukuba iindawo zembuyekezo ezimiselweyo zinokukhethwa kwiimeko ezahlukeneyo, kuyimfuneko ukwenza iseti yeendawo zembuyekezo ze-washer kunye ne-shaft ezinobukhulu obahlukeneyo kunye nobukhulu kwangaphambili ukuze kukhethwe imodeli yevalvu yokulawula i-hydraulic ngexesha lokuhlanganiswa.
Indlela yokulungisa
Ivalvu ihlanganiswa ngendlela yokulungisa, iindawo zinokucutshungulwa ngokwendlela echanekileyo yezoqoqosho, kwaye emva koko ubungakanani obuthile obunokulungiswa kunye nesiphumo sokuhlawula bunokulungiswa ngexesha lokuhlanganiswa, ukuze kufezekiswe injongo yokuhlanganiswa echaziweyo. Umzekelo, umzimba wesango kunye nevalvu yevalvu yesango le-wedge, ngenxa yeendleko eziphezulu zokucubungula zokufezekisa iimfuno zokutshintshiselana, uninzi lwabavelisi bamkela inkqubo yokulungisa. Oko kukuthi, ekugayweni kokugqibela komphezulu wokutywina kwesango ukulawula ubungakanani bokuvula, ipleyiti kufuneka ihambelane nobukhulu bokuvula komphezulu wokutywina umzimba wevalvu, ukuze kufezekiswe iimfuno zokugqibela zokutywina. Le ndlela yonyusa inkqubo yokufanisa ipleyiti, kodwa yenza lula kakhulu iimfuno zokuchaneka kobukhulu benkqubo yokucubungula yangaphambili. Ukusebenza ngobuchule kwenkqubo yokufanisa ipleyiti ngabasebenzi abakhethekileyo akuyi kuchaphazela ukusebenza kakuhle kwemveliso iyonke. Inkqubo yokuhlanganisa ivalvu: iivalvu zihlanganiswa nganye nganye kwindawo esisigxina. Ukuhlanganiswa kweenxalenye kunye neenxalenye kunye nokuhlanganiswa ngokubanzi kweevalvu kwenziwa kwindawo yokusebenzela yokuhlanganisa, kwaye zonke iindawo kunye neenxalenye ezifunekayo zithuthwa ziye kwindawo yokuhlanganisa. Ngokwesiqhelo, mangaphi amaqela abasebenzi anoxanduva lokuhlanganisa iindawo kunye neNdibano Jikelele ngaxeshanye, nto leyo engagcini nje ngokunciphisa umjikelo wokuhlanganisa, kodwa ikwanceda ukusetyenziswa kwezixhobo ezikhethekileyo zokuhlanganisa, kwaye ineemfuno eziphantsi kwinqanaba lobugcisa labasebenzi.
