Iimpazamo eziqhelekileyo kunye nemilinganiselo yokuthintela i-valves yesango

Njengesixhobo esibalulekileyo seplanga,I-valves yesangozisetyenziswa ngokubanzi kumashishini amaninzi anjengeoyile, igesi yendalo, unyango lwamanzi, ishishini leekhemikhali, kunye nombane. Umsebenzi wayo ophambili kukulawula ukuhamba kunye nokusika ulwelo ngokuphakamisa kunye nokuthoba iplate ye-valve. Nangona kunjalo, njengazo zonke izixhobo zoomatshini, i-valve yesango inokuba neempazamo ezithile ngexesha lokusetyenziswa kwexesha elide. Ukuqonda unobangela kunye namanyathelo othintelo lweziphoso eziqhelekileyo kuya kunceda ukuphucula ubomi benkonzo kunye nokuzinza okusebenzayo kwamasango.

1. Ivalve ayinakuvalwa ngokupheleleyo

Impazamo yempazamo:

Xa i-valve yesango ayinakuvalwa ngokupheleleyo, ulwelo luseza kungena kwivalve, kubangela ukuvuza kwepayimu okanye ukuhamba okungalawulekiyo. Unobangela oqhelekileyo ubandakanya ukunxiba umphezulu wokutywina kwesihlalo sevali okanye iplate ye-valve, umcimbi wezombutho unamathele okanye ukhuphelo.

UVAVANYO UVAVANYO:

Ukunxiba umphezulu: Umsebenzi wenguqulelo yexesha elide kunye nokugungxulwa kwamanzi kunokubangela ukunxibisa umphezulu wokutywina kwesitulo sevali kunye neplate ye-valve, kukhokelela ekutywineni.

Umcimbi welinye ilizwe: Ukungcola okanye umcimbi welinye ilizwe kumbhobho unokuthintelwa kwisitulo se-vali okanye phakathi kweplate ye-valve kunye nesitulo se-valve, sithintela ivalve ivaliwe ngokupheleleyo.

I-Sorisosion: Ukusebenza kwexesha elide kubushushu obuphezulu, uxinzelelo oluphezulu okanye imeko yemithombo yeendaba, indawo yokutywina kwevalve ithambekele ekubonakaleni, echaphazela isiphumo sokutywina.

Amanyathelo okuthintela:

Jonga rhoqo umphezulu wokutywina kwe-valve kwaye ulungise okanye ukutshintshwa kwamacandelo okutywina ngexesha.

Coca i-pipeling rhoqo ukuthintela ukungcola ekungeneni kwivalve, ngakumbi xa ivalve ivaliwe.

Khetha ibhulukhwe efanelekileyo ye-valve kunye nezinto zokutywina ngokweempawu ze-fluid ukunciphisa ukuncipha kwemveliso.

I-2. Ivalve kunzima ukusebenza okanye ayinakusebenza

Impazamo yempazamo:

II-Palve yesangoKunzima kakhulu ukusebenza ngexesha lenkqubo yokuvula okanye yokuvala, kwaye akunakwenzeka ukuba ujike i-valve stem okanye ivili levali yevalve. Esi siphoso sihlala sibangelwa sisiqu se-valve sibambelela okanye iindawo zangaphakathi zomzimba wevali onakalisiweyo.

UVAVANYO UVAVANYO:

I-valve stem comrosion okanye ukonakaliswa: I-valve stem ingabakho okanye i-valve ivele okanye ichaphazele imeko yeqondo eliphakamileyo, ingakumbi phantsi kweemeko ezinobungozi, ezikhokelela kwi-valve stem kunye nebhulukhwe yevali.

Ukunganyamezeli okungonelanga: Ukuvulwa nokuvalwa kwe-valve yesango kuxhomekeke kwi-vilve efanelekileyo phakathi kwe-valve stem kunye nebhulukhwe yevali. Ukuba kukho ukunqongophala kokuthambisa okufanelekileyo, ukungcungcutheka kuya kunyuka, okuya kubangela ubunzima ukusebenza.

I-block yelinye ilizwe: Ukuba umba welinye ilizwe lungena kwivalve, kunokubangela i-valve stem ukuba inamathele kwaye isilele ukusebenza ngesiqhelo.

Amanyathelo okuthintela:

Sebenzisa ioyile efanelekileyo okanye igrisi, jonga kwaye uqinisekisile rhoqo.

Kwindawo enoburharha kakhulu okanye amaqondo obushushu aphezulu, ukunganyangeki kweqondo lokunganyangeki kunye neqondo lokunganyangeki eliphezulu kwaye lifanele lisetyenziselwe ukwenza isiqu se-valve, kwaye isiqu se-valve kufuneka sihlolwe rhoqo ngomonakalo.

Ngexesha lokufakwa, qinisekisa ukuba ngaphakathi kwivalve icocekile ukunqanda umcimbi welinye ilizwe ukuba angangeni.

I-3. I-Valve Easakage

Impazamo yempazamo:

Xa ivalve yesango ivaliwe, kusekho ukuvuza kwamanzi, ngakumbi kwixinzelelo oluphezulu, ubushushu obuphezulu okanye iindawo zokuzonwabisa ezizeleyo, apho ingxaki yokuvuza ibaluleke kakhulu kwaye inokubangela iingozi zokhuseleko okanye inkunkuma yokhuseleko.

UVAVANYO UVAVANYO:

Ukuphatha okanye ukunxiba kumhlaba wokutywina: Umhlaba wokutywina kweplate ye-valve kunye nesitulo sevali, okanye sinxibe okanye siphethwe emva kokusetyenziswa kwexesha elide, okukhokelela ekunciphiseni kwexesha elide.

Isitulo se-valve okanye ungcoliseko lwe-valve, ukungcola, ii-sediments okanye iikhemimenti kwipibhoyili kunokungcolisa umphezulu wokutywina, ukunciphisa ukusebenza kokutywina.

Ukufakelwa okungalunganga: Ukuba ivalve ayifakwanga kakuhle, kunokubangela ukutywinwa kakubi, okunokukhokelela kwiingxaki zokuvuza.

Amanyathelo okuthintela:

Xa uthenga kwaye usebenzisa i-valvengo yesango, izixhobo zesango kunye nokungaxhathisi kufuneka kukhethwe ukuqinisekisa ukusetyenziswa kwexesha elide.

Jonga umphezulu wokutywina rhoqo kwaye ulungise okanye ukufaka indawo enxibe iimpahla okanye ezonakeleyo ngexesha.

Qinisekisa ukuba ivalve ifakwe ngokungqinelana nenkcazo yokuphepha ukuqiniswa kokuqinisa ngaphezulu okanye ukufakwa kwe-eccentric, kuya kuchaphazela iziphumo zokutywina.

I-4. I-valve ivutha okanye iyenza ingxolo enkulu

Impazamo yokubonakala: Ngexesha lokuvula nokuvalwa kwevalve, ukungaqhelekanga okanye ingxolo yenzeka. Le ngxaki ihlala yenzeka xa ivalve ivuliwe okanye ivaliwe, enokuchaphazela ukusebenza okuzinzileyo kwale nkqubo kwaye ikhawuleze ilahleko yevalve.

UVAVANYO UVAVANYO:

Ireyithi yokuhambahamba kakhulu: Xa inqanaba lokuhamba kwamanzi liphezulu kakhulu, ngakumbi xa ivalve ivuliwe, isiphithiphithi sinokwenzeka xa i-fluid idlula kwivalve, ebangela ingxolo okanye ingxolo.

Uyilo olungalunganga lwe-valve: Ukuba umsebenzi we-valve akwenziwa ngendlela efanelekileyo, ngakumbi xa kufanelekile phakathi kweplate ye-valve kunye nesitulo sevali, sinokubangela ukuntywila kwevali.

I-Valve ivuliwe ngokukhawuleza: Ukuvula ngokukhawuleza i-Palve yesango kunokubangela ifuthe lokutyibilika kwamanzi okanye ifuthe le-fluid, kukhokelela kwingxolo kunye nengxolo.

Amanyathelo okuthintela:

Yenza ngokufanelekileyo isantya sokuvula i-veli ukunqanda ifuthe elibangelwe kukuvula ngokukhawuleza.

Lawula ireyithi yokuhamba kwipayipi yokuqinisekisa ukuba ulwelo luhlala luzinzile xa uhamba evaliwe.

Xa uyila kwaye ukhetha, khetha uhlobo lweValve olufanelekileyo kunye nobukhulu ukuqinisekisa ukuba ivalve inokuziqhelanisa neyona ndawo isebenzayo.

I-5. Itywina lokuthengisa

Ukunyaniseka kokunyaniseka:

Isiphelo setywina lokusilela kuthetha ukuba ulwelo alunakuhlukaniswa ngokupheleleyo, idla ngokubonakalaliswa ngokuvuza kwamanzi, kwaye inokuchaphazela yonke inkqubo yepayipi. Zininzi izizathu zokungaphumeleli kwetywina, ezihlala zinxulumene nendawo yokusetyenziswa, iimeko zokusebenza kunye nezixhobo zetyhefu.

UVAVANYO UVAVANYO:

Ukunxiba okubangelwa kukusetyenziswa kwexesha elide: Umphezulu wokutywina kwesihlalo sevali kunye neplate ye-valve iya kunxiba kancinci njengoko ixesha lokusetyenziswa linyuka, kwaye ukusebenza kokutywina kuya kuncipha.

Iqondo lobushushu kunye noxinzelelo: Ubushushu bequbuliso okanye utshintsho loxinzelelo luya kubangela ukuba izinto zokutywina zikhule okanye zekhontrakthi, zibangela ukungaphumeleli kwetywina.

Ukunyanzelwa kunye nokuphendula kwamachiza: Kumanye amajelo eendaba ezithile, indawo yevali yokutywina inokutsalwa okanye iphendule ngokufanelekileyo, ukunciphisa isiphumo sokutywina.

Amanyathelo okuthintela:

Khetha izixhobo ezifanelekileyo zokutywina ngokweendawo eziphakathi zenkqubo yepayipi yokuphepha ukungaphumeleli ngenxa yeqondo lobushushu, uxinzelelo okanye uxinzelelo okanye uxinzelelo okanye uxinzelelo okanye uxinzelelo okanye uxinzelelo okanye iingxaki zoxinzelelo.

Jonga rhoqo umphezulu wokutywina, fumana iimpawu zokunxiba kunye nokulungisa okanye ukutshintsha ngexesha.

Kumaqondo obushushu aphezulu okanye kwimo yokusebenza ephezulu yokusebenza, sebenzisa ubushushu obuphezulu kunye nezinto eziphezulu zokunganyangeki zenze umhlaba wokutywina ukuqinisekisa ukusebenza kwe-valve.

Ukusilela okuqhelekileyo kweI-valves yesangozihlala zihambelana nokusetyenziswa kwexesha elide, ukusebenza okungafanelekanga okanye izinto zokusingqongileyo. Ngokuhlolwa rhoqo kunye nesondlo esifanelekileyo, ezi ngxaki zinokuthintelwa ngokufanelekileyo, ubomi benkonzo yevali bunokwandiswa, kwaye ukhuseleko kunye nozinzo lwenkqubo yombhobho bunokuphuculwa. Ukufunyanwa kwexesha ngexesha elifanelekileyo kunye nokulungiswa kweempazamo kunokuqinisekisa ukuba i-valve yesango idlala indima yayo efanelekileyo kumaxesha anzima, ukunciphisa iindleko zokulondolozwa kunye nexesha lokudodobala.
