Iimfuno zofakelo lwevalvu yesikhululo samandla iinzuzo zesakhiwo kunye neenkcukacha zobugcisa

I-valve ikwinkqubo yolwelo, esetyenziselwa ukulawula isalathiso solwelo, uxinzelelo, isixhobo sokuhamba, kukwenza umbhobho kunye nesixhobo esiphakathi (ulwelo, igesi, umgubo) ukuhamba okanye ukumisa kwaye inokulawula ukuhamba kwesixhobo. I-Valve yinxalenye yolawulo lwenkqubo yokuhambisa ulwelo lwepayipi, esetyenziselwa ukutshintsha icandelo lendlela kunye nesikhokelo sokuhamba okuphakathi, kunye ne-diversion, cut-off, throttling, check, shunt okanye overflow relief relief kunye neminye imisebenzi. Iivalvu zolawulo lolwelo ukusuka kwiivalvu zeglowubhu ezilula ukuya kwezo zisetyenziswa kwiinkqubo zolawulo oluzenzekelayo ezintsonkothileyo, ezineentlobo ngeentlobo zeentlobo kunye neenkcukacha, ezisusela kubukhulu obuqhelekileyo ukusuka kwiivalvu zesixhobo ezincinci ukuya kwiivalvu zemibhobho yeshishini ukuya kutsho kwi-10m. Ingasetyenziselwa ukulawula ukuhamba kwamanzi, umphunga, ioli, igesi, udaka, zonke iintlobo zemithombo yeendaba ezonakalisayo, isinyithi solwelo kunye nolwelo lwe-radioactive kunye nezinye iintlobo zolwelo, uxinzelelo olusebenzayo lwevalvu lunokuba lusuka ku-0.0013mpa ukuya ku-1000MPa uxinzelelo oluphezulu, ubushushu bokusebenza. ingaba c-270℃ ukuya 1430℃ lobushushu eliphezulu. Ulawulo lweValve lunokusebenzisa iindlela ezahlukeneyo zokuhambisa, ezifana ne-manual, umbane, i-hydraulic, i-pneumatic, i-turbine, i-electromagnetic, i-electromagnetic hydraulic, i-hydraulic yombane, i-pneumatic, i-spur gear, i-bevel gear drive, njl. Kuxinzelelo, ubushushu okanye enye ifom phantsi kwentshukumo yemiqondiso yesivamvo, isenzo, ngokwemfuno yogcino okanye ayixhomekeke kwimiqondiso yoluvo lokuvula okanye ukuvala lula, ukuxhomekeka kwi-drive okanye kwi-othomathikhi ye-othomathikhi eyenza ukuvula nokuvala ivalve ukuphakamisa, ukutyibilika, indawo okanye intshukumo ejikelezayo, ukuze utshintshe ubungakanani bezibuko ukuze uqonde umsebenzi wolawulo. Iimfuno zokufakela i-1, phambi kokufakwa kwevalve, kufuneka ihlolisise ngononophelo imodeli yevalve, inkcazo kunye noyilo; 2, ngokwemodeli yevalve kunye nemiyalelo yefektri ukujonga ukuba ivalve ingasetyenziswa kwiimeko ezifunekayo; 3. Xa uphakamisa i-valve, intambo kufuneka iboshwe kwi-flange yokudibanisa kwe-valve yomzimba kunye ne-valve cover, kwaye ingabotshwa kwi-handwheel okanye kwi-stem, ukuze ingonakalisi i-stem kunye ne-handwheel; 4. Xa ivalve ifakwe kumbhobho othe tyaba, isiqu sevalve kufuneka siphakame ngokuthe nkqo, kwaye asivumelekanga ukuba sifakwe phantsi; I-5, xa ufaka i-valve, ayiyi kusebenzisa imodi yokudibanisa isibini esinyanzelwayo, ukwenzela ukuba ingabangela umonakalo ngenxa yokungalingani kwamandla; I-6, i-valve yesango ye-stem akufanele ifakwe kwindawo ephantsi komhlaba emanzi, ukuze ingagcini i-rust. Iimfuno zeNdibano iindawo ezicocekileyo kufuneka zitywinwe ukuze kufakwe. Iimfuno zenkqubo yokufakela zezi zilandelayo: 1. Indawo yokusebenzela yokufakela kufuneka icoceke, okanye imise iindawo ezicocekileyo zexeshana, ezifana nelaphu elinemibala esanda kuthengwa okanye ifilimu yeplastiki, ukuthintela uthuli ukuba lungangeni ngexesha lofakelo. I-2, abasebenzi bendibano kufuneka banxibe iimpahla zomqhaphu ezicocekileyo zomsebenzi, banxibe ikepusi esulungekileyo yomqhaphu, iinwele azikwazi ukuvuza, iinyawo zinxibe izihlangu ezicocekileyo, izandla zinxibe iiglavu zeplastiki, zithobe. 3, izixhobo zokuhlanganisa kufuneka zihlanjululwe ngaphambi kokuhlanganisana, ukuqinisekisa ukuba zicocekile. IiMfuno zoKwamkelwa Ukwamkelwa ngokuhambelana ne-HG 20202-2000 Ikhowudi yoKwakha kunye noKwamkeleka koBunjineli bokunciphisa. Ngaphambi kokuhlanganisana, sula inxalenye nganye ngephepha lokucoca elichanekileyo, khetha iikona ezifileyo, kwaye iphepha lokucoca elinombala ongatshintshiyo lifanelekile. I-1, imodeli yevalvu kufuneka iboniswe ngokweemfuno zenombolo ye-SIZWE. Ukuba umgangatho weshishini, kufuneka ubonise inkcazo efanelekileyo yemodeli. I-2, i-valve esebenzayo yoxinzelelo, iimfuno ≥ umbhobho wokusebenza koxinzelelo, ngaphandle kokuchaphazela ixabiso lendawo, i-valve inokuthwala uxinzelelo kufuneka ibe mkhulu kunoxinzelelo lwemibhobho yokwenyani. 3, imigangatho yokwenziwa kwevalvu, kufuneka ichaze isiseko senombolo yomgangatho KAZWELONKE, ukuba umgangatho weshishini, isivumelwano sokuthengwa kwempahla kufuneka sincanyathiselwe kuxwebhu lweshishini. Ukufumana iinkcukacha ezithe vetshe, nceda ujonge: Iimfuno zofakelo loLwakhiwo lwevalve Izinto eziluncedo kunye neenkcukacha zobuchule zevalvu yesikhululo samandla “Ivalve yesikhululo samandla”, ekwaziwa ngokuba yivalve yesikhululo samandla, isetyenziswa ikakhulu kumbhobho weendlela ezahlukeneyo zezikhululo zamandla obushushu, ukusika. okanye ukudibanisa imidiya yombhobho. Indawo esetyenziswayo: amanzi, umphunga kunye nolunye uhlobo olungadlekiyo. Xa kuthelekiswa nezinye iimveliso zevalve, ivalve yesikhululo samandla ibonakala ngobushushu obuphezulu kunye noxinzelelo oluphezulu, uyilo olukhethekileyo lokuzitywina, okukhona uxinzelelo luphezulu, kokukhona luthembekile ukutywinwa. Ngenxa yokusebenza okukhethekileyo, iimpawu zobugcisa kunye neemeko zokusebenza, umkhiqizo wenze iimpawu ukuba ezinye iimveliso azikwazi ukutshintshwa. Isihlalo sevalve kunye ne-disc yokutywinwa kwendawo zenziwe nge-cobalt-based carbide plasma spray welding, kunye nokuchasana kakuhle kwe-abrasion kunye nokuchasana kwe-abrasion.
I. Ukwaziswa ngokufutshane kwevalvu yesikhululo samandla
“Ivalve yesikhululo samandla” ikwabizwa ngokuba sisitishi sombane, esilungele izikhululo zamandla ombane oshushu kwiinkqubo ezahlukeneyo zombhobho, esikiweyo okanye ofakwe kumbhobho ophakathi. Indawo esetyenziswayo: amanzi, umphunga kunye nolunye uhlobo olungadlekiyo. Xa kuthelekiswa nezinye iimveliso zevalve, ivalve yesitishi samandla ibonakaliswa ngubushushu obuphezulu kunye noxinzelelo oluphezulu, uyilo olukhethekileyo lokuzitywina, okukhona uxinzelelo luphezulu, kokukhona luthembekile ukutywinwa. Ngenxa yokusebenza okukhethekileyo, iimpawu zobugcisa kunye neemeko zokusebenza, umkhiqizo wenze iimpawu ukuba ezinye iimveliso azikwazi ukutshintshwa.
