Ivalvusisixhobo esisetyenziswa ekudluliseni nasekulawuleni igesi kunye nolwelo olunembali yeminyaka eliwaka ubuncinane.
Okwangoku, kwinkqubo yemibhobho yamanzi, ivalvu elawulayo yeyona nto ilawulayo, kwaye umsebenzi wayo ophambili kukwahlula izixhobo kunye nenkqubo yemibhobho, ukulawula ukuhamba kwamanzi, ukuthintela ukubuya kwamanzi, ukulawula nokukhupha uxinzelelo. Ekubeni kubaluleke kakhulu ukukhetha ivalvu elawulayo efanelekileyo kwinkqubo yemibhobho, kubaluleke kakhulu nokuqonda iimpawu zevalvu kunye namanyathelo kunye nesiseko sokukhetha ivalvu.
Uxinzelelo oluqhelekileyo lwevalvu
Uxinzelelo oluqhelekileyo lwevalvu lubhekisa kuyilo olunikiweyo loxinzelelo olunxulumene namandla oomatshini wezinto zombhobho, oko kukuthi, luxinzelelo olusebenzayo oluvumelekileyo lwevalvu kubushushu obuchaziweyo, oluhambelana nezinto zevalvu. Uxinzelelo olusebenzayo alufani, ngoko ke, uxinzelelo oluqhelekileyo luyiparameter exhomekeke kwizinto zevalvu kwaye lunxulumene nobushushu obuvumelekileyo bokusebenza kunye noxinzelelo olusebenzayo lwezinto.
Ivalvu sisixhobo esikwinkqubo yokujikeleza kwegazi ephakathi okanye inkqubo yoxinzelelo, esetyenziselwa ukulungisa ukuhamba okanye uxinzelelo lwesixhobo. Eminye imisebenzi ibandakanya ukuvala okanye ukuvula imidiya, ukulawula ukuhamba, ukutshintsha indlela ukuhamba kwemidiya, ukuthintela ukubuyela kwemidiya, kunye nokulawula okanye ukukhupha uxinzelelo.
Le misebenzi ifezekiswa ngokulungisa indawo yokuvalwa kwevalvu. Olu hlengahlengiso lungenziwa ngesandla okanye ngokuzenzekelayo. Ukusebenza ngesandla kuquka nokusebenza kokulawula idrayivu ngesandla. Iivalvu ezisebenza ngesandla zibizwa ngokuba ziivalvu ezenziwe ngesandla. Ivalvu ethintela ukubuya kwamanzi ibizwa ngokuba yivalvu yokujonga; leyo ilawula uxinzelelo lokukhulula ibizwa ngokuba yivalvu yokhuseleko okanye ivalvu yokukhulula ukhuseleko.
Okwangoku, ishishini leevalvu likwazile ukuvelisa uluhlu olupheleleyo lweiivalvu zesango, iivalvu zeglobe, iivalvu ze-throttle, iivalvu zeplagi, iivalvu zebhola, iivalvu zombane, iivalvu zokulawula i-diaphragm, iivalvu zokujonga, iivalvu zokhuseleko, iivalvu zokunciphisa uxinzelelo, iitraphu zomphunga kunye neevalvu zokuvala ezingxamisekileyo. Iimveliso zeevalvu zeendidi ezili-12, iimodeli ezingaphezu kwama-3000, kunye neenkcukacha ezingaphezulu kwama-4000; uxinzelelo oluphezulu lokusebenza yi-600MPa, ububanzi obuphezulu obuqhelekileyo yi-5350mm, ubushushu obuphezulu bokusebenza yi-1200℃, ubushushu obuphantsi bokusebenza yi -196℃, kwaye indlela efanelekileyo ngamanzi, umphunga, ioyile, igesi yendalo, imithombo enamandla yokubola (njenge-asidi ye-nitric egxininisiweyo, i-asidi ye-sulfuric egxininisiweyo ephakathi, njl.njl.).
Nika ingqalelo ekukhetheni iivalvu:
1. Ukuze kuncitshiswe ubunzulu bomhlaba ogquma umbhobho,ivalvu yebhabhathaneNgokuqhelekileyo ikhethwa kwipayipi enobubanzi obukhulu; eyona ngxaki iphambili yevalvu yebhabhathane kukuba ipleyiti yebhabhathane ithatha indawo ethile yamanzi, nto leyo enyusa ukulahleka kwentloko ethile;
2. Iivalvu eziqhelekileyo ziqukaiivalvu zebhabhathane, iivalvu zesango, iivalvu zebhola kunye neevalvu zeplagi, njl. Uluhlu lweevalvu ezisetyenziswa kuthungelwano lokuhambisa amanzi kufuneka luqwalaselwe xa kukhethwa.
3. Ukuphoswa nokulungiswa kweevalvu zebhola kunye neevalvu zeplagi kunzima kwaye kuyabiza, kwaye ngokubanzi zifanelekile kwiipayipi ezincinci neziphakathi. Iivalvu zebhola kunye neevalvu zeplagi zigcina iingenelo zevalvu yesango elinye, ukumelana nokuhamba kwamanzi okuncinci, ukutywinwa okuthembekileyo, isenzo esiguquguqukayo, ukusebenza okulula kunye nokugcinwa. Iivalvu zeplagi nazo zinezibonelelo ezifanayo, kodwa icandelo lokudlulisa amanzi alilo mjikelo ugqibeleleyo.
4. Ukuba ayinampembelelo ingako kubunzulu bomhlaba ogqunyiweyo, zama ukukhetha ivalvu yesango; ukuphakama kwevalvu yesango lombane ivalvu yesango ethe nkqo enobubanzi obukhulu ichaphazela ubunzulu bombhobho ogqunywe ngumhlaba, kwaye ubude bevalvu yesango ethe nkqo enobubanzi obukhulu bunyusa indawo ethe tye ehlala umbhobho kwaye buchaphazela ulungiselelo lweminye imibhobho;
5. Kwiminyaka yakutshanje, ngenxa yokuphuculwa kwetekhnoloji yokuthunga, ukusetyenziswa kwe-resin sand casting kunokuthintela okanye kunciphise ukucutshungulwa koomatshini, ngaloo ndlela kuncitshiswe iindleko, ngoko ke kufanelekile ukuphonononga ukuba kunokwenzeka na ukuba iivalvu zebhola ezisetyenziswa kwiipayipi ezinkulu. Ngokuphathelele umgca wokwahlulahlula ubungakanani be-caliber, kufuneka uqwalaselwe kwaye wahlulwe ngokwemeko ethile.
