Ihowuliseleli yaseChina abaVelisi beValve yeBhola yeFlange – iAptha yeFlange – DIKAI

Ufakelo lweflange lusetyenziswa kwizicelo ezibango ngenxa yokufaneleka kwazo kuxinzelelo oluphezulu, ukothuka, kunye nokungcangcazela. Bakwavumela ukudibanisa okulula phakathi kwe-hose kunye ne-tube okanye umbhobho, kunye naphakathi kwemigca eqinile.

Ufakelo lwetyhubhu enkulu kune-intshi enye kwidayamitha yangaphandle, kukho imiba ekuqiniseni okusebenzayo kunye nofakelo. Akunjalo kuphela ezi zidibanisi zifuna ii-wrenches ezinkulu, kodwa abasebenzi kufuneka bakwazi ukusebenzisa i-torque eyaneleyo efunekayo ukuze kuqiniswe ngokufanelekileyo. Ufakelo lufuna ukuba abaqulunqi benkqubo babonelele ngesithuba esiyimfuneko kubasebenzi ukuze bakwazi ukujiwuzisa ezo zitshixo zinkulu. Ukuba oko bekungafanelekanga ngokwaneleyo, ukudityaniswa okufanelekileyo kwezi zifakelo kunokuthotywa ngenxa yokuphelelwa ngamandla kunye nokudinwa okwandileyo kwabasebenzi abazama ukusebenzisa isixa esisebenzayo setorque. I-split-flange fitting isombulula le miba.

Izixhobo zeFlange zinokumelana okuphezulu kokukhulula, kwaye zinokudityaniswa ngokulula. Ezi zifakelo zisetyenziswa kwiindawo ezixineneyo. Okwangoku, ngaphezulu kwama-700 obungakanani obahlukeneyo kunye nolungelelwaniso lwe-split-flange fittings luyafumaneka, okwenza kube lula ukuba umntu afumaneke kwisicelo esithile.

Ukufakelwa kwe-split-flange kusebenzisa i-rubber O-rings ukutywina amalunga kwaye iqulethe i-pressurized fluid. I-O-ring ihleli kwi-groove kwi-flange, kwaye emva koko idibanisa nomphezulu we-port's flat. I-flange ke idityaniswe kwizibuko ngeebholiti ezine zokukhwela. Iibholithi ziqina ukuya ezantsi kwiiclamps zeflange, ngaloo ndlela zisusa imfuno yeziklintshi ezinkulu zokudibanisa amacandelo etyhubhu yobubanzi obukhulu.

Izinto zoKufakela i-Split-Flange

Izinto ezithathu kufuneka zibe kwindawo nakwezona zisisiseko zofakelo lweflange. Zezi:

1. I-O-ring engena kumjelo wobuso weflange;
2. Iziqingatha ezibini ezibambeneyo zokukhwelana ezineebholiti ezifanelekileyo zokudityaniswa phakathi kwendibano yeflange eyahlulayo kunye nomphezulu wokukhwelana;
3. Intloko edibeneyo edibeneyo ngokusisigxina, ngokuqhelekileyo iboshwe okanye ifakwe kwi-tube.

Iingcebiso zokuFakelo oluFanelekileyo usebenzisa iSplit-Flange Fittings

Xa ufaka i-split-flange fittings, iindawo zokukhwelana ezicocekileyo nezigudileyo ziyimfuneko. Ngaphandle koko, amajoyina aya kuvuza. Ukuhlola amalungu okukhangela, ukukrwela kunye nokufaka amanqaku kunokuthintela iingxaki ezizayo. Kubalulekile ukuqaphela ukuba iindawo ezirhabaxa nazo ziya kuba negalelo ekunxityweni kwe-O-rings.

Kwiimeko apho ubudlelwane be-perpendicular bubaluleke kakhulu, kufuneka kuqinisekiswe ukuba icandelo ngalinye liyahlangabezana nokunyamezelana okufanelekileyo ukwenzela ukuthintela ukuvuza kwamanzi ngoqhagamshelwano.

Nangona iindibano ze-split-flange eziyilwe ngokufanelekileyo zibona igxalaba le-flange liphuma kwi-0.010 ukuya kwi-intshi ye-0.030 ngaphaya kobuso be-clamp, akukho qhagamshelwano lwee-halves ezibambayo kunye nomphezulu wokukhwela okwenzekayo.

Apho kufakelo loqhagamshelo lweflange lubandakanyekayo, netorque kufuneka ifakwe kuzo zone iibholithi zeflange. Oku kuya kunceda ukuphepha ukudalwa kwe-gap enokubangela i-o-ring extrusion xa uxinzelelo oluphezulu lusetyenzisiwe. Kananjalo, xa kuqiniswa iibholithi, nganye kufuneka iqiniswe ngokuthe ngcembe nangokulinganayo kusetyenziswa ipateni yomnqamlezo. Akukhuthazwa ukusebenzisa izitshixo zomoya kule njongo, njengoko uxinzelelo alulawulwa lula kwaye lunokubangela ukuqiniswa ngokugqithiseleyo kweebholiti.

Ukunyuka kweflange kunokwenzeka xa ibholithi enye kuphela kwezine iqiniswe ngokufanelekileyo. Oku kunokubangela ukucofa i-O-ring. Xa oku kusenzeka, ukuvuza kwijoyinti phantse akunakuphepheka. Enye imeko enokuthi yenzeke ngenxa yokuba ibholithi enye kuphela kwezine ziqiniswe kakuhle kukugotywa kweebholiti xa zonke ziqinisiwe ngokupheleleyo. Oku kwenzeka xa iiflange zigobela ezantsi de zibe phantsi kwizibuko lobuso, nto leyo ebangela ukuba iibholithi zigobele ngaphandle. Xa ukugoba zombini iiflange kunye neebholiti kwenzeka, oku kunokubangela ukuba i-flange iphakame egxalabeni, ibangele ukuba amalunga avuze.
