Yintoni unobangelaukuvuza kweflange? Abasebenzi bomzi-mveliso waseFransi bashwankathela ezi zizathu zisixhenxe zilandelayo zokuvuza, benethemba lokunceda abahlobo abasweleyo.
1, ukuvuza kweflangeisizathu: umlomo ongalunganga
Umdibaniso odibeneyo apho umbhobho kunye ne-flange zi-perpendicular, kodwa ezimbiniiiflangeazigxininisi. Iiflangeayigxininisi, ngoko ke iibholiti ezijikelezileyo azikwazi ukudlula ngokukhululekileyo kumngxuma webholiti. Xa kungekho naziphi na ezinye iindlela, ukuphinda kuphinde kufakwe iibholiti okanye iibholiti ezincinci zifakwe kwimingxunya yebholiti, nto leyo enciphisa uxinezeleko kwiiflange zombini. Ngaphezu koko, ukutywinwa kwendawo yokutywina kukwacalanye, ekulula kakhulu ukuvuza.
2, ukuvuza kweflangeizizathu: i-corrosion effect
Ngenxa yokuba i-gasket iye yachithwa yi-corrosive medium ixesha elide, i-gasket iye yatshintsha iikhemikhali. I-Corrosive medium ingena kwi-gasket, eqala ukuthamba kwaye ilahlekelwe nguxinzelelo, ibangeleiflangeukuvuza.
I-3, ukuvuza kwe-flange kubangela: i-bias
Ukuphambuka kubhekisa kumbhobho kunye neflange azikho nkqo, iziko elahlukileyo, umphezulu weflange awuhambelani. Ukuvuza kweFlange kwenzeka xa uxinzelelo oluphakathi lwangaphakathi ludlula uxinzelelo lomthwalo we-gasket. Le meko ibangelwa ikakhulu kukufakelwa okanye ukulungiswa kwaye kulula ukuyibona. Ngethuba nje uhlolo lwangempela lugqityiwe, ingozi inokuphetshwa.

I-4, ukuvuza kwe-flange kubangela: ukuvulwa komlomo
Ukuvula kubhekisa kwisikhewu seflange sikhulu kakhulu. Xa i-flange clearance inkulu kakhulu kwaye ibangela imithwalo yangaphandle (efana ne-axial okanye imithwalo egobayo), i-gasket iya kuchaphazeleka okanye ishukunyiswe, ilahlekelwe ngamandla ayo oxinzelelo kwaye ngokuthe ngcembe ilahlekelwe ngamandla e-kinetic yesitywina, okukhokelela ekungaphumelelini.
I-5, ukuvuza kwe-flange kubangela: isenzo soxinzelelo
Xa ufaka i-flanges, ukudibanisa kweeflange ezimbini kusemgangathweni ngakumbi, kodwa kwimveliso yenkqubo, emva kokuba umbhobho ungene phakathi, ubushushu bombhobho buya kutshintsha, okubangele ukwanda okanye ukuguqulwa kombhobho, ukwenzela ukuba i-flange ibe phantsi kokugoba. umthwalo okanye ukucheba amandla, okunokuthi kukhokelela ngokulula ekungaphumeleli kwe-gasket.
6, flange ukuvuza isizathu: umngxuma engalunganga
Umngxuma ongalunganga ubonisa ukuba umbhobho ugxininise kunye ne-flange, kodwa umgama phakathi kweebholithi ezimbini mkhulu ngokumalunga nomngxuma webholithi. Umngxuma ongalunganga uya kubangela ukuba i-bolt igxininise kwaye ayiyi kususa amandla. Oku kuya kudala amandla okucheba kwibholiti kwaye ibholithi iya kuqhawuka ixesha elide, nto leyo ekhokelela kukusilela kwetywina.
7. Ukuvuza kwe-Flange kubangela: ukwandiswa kwe-thermal kunye nokunciphisa okubandayo
I-bolt yandisa okanye iikhontrakthi ngenxa yokwandiswa kwe-thermal kunye ne-contraction ye-fluid medium, ngoko i-gasket iya kudala i-gap, kwaye i-medium iya kuvuza ngoxinzelelo.
Ezi ngongoma zisixhenxe zingasentla zizizathu eziqhelekileyo zokuvuza kwe-flange. Ukuba ufuna ukwazi ngakumbi malunga ne-flange kunye ne-elbow okanye i-odolo ye-flange elbow, unokuqhagamshelana nathi. Sijonge phambili ukusebenzisana nawe.
