Ukuphathwa okuyisisekelo kwemishini "ukuvuza"

Ukuphathwa kokukhiqizwa okuphephile nokuphucuzekile kuhlanganisa ukuvuza kukawoyela, ukuvuza kwamanzi, ukuvuza komusi, ukuvuza kwentuthu, ukuvuza komlotha, ukuvuza kwamalahle, ukuvuza kwempushana kanye nokuvuza kwegesi, okuyilokho esikubiza ngokuthi “ukugijima, ukukhipha, ukuconsa nokuvuza”. Namuhla, sifingqa ezinye zezinyathelo zokuvimbela "zokugijima, ukukhipha, ukuconsa kanye nokuvuza" ukuze sibhekisele. I izinyathelo zokuvimbela amanzi kanye umusi ukuvuza of valve. 1. Wonke ama-valve kufanele abe ngaphansi kwamazinga ahlukene okuhlolwa kwe-hydrostatic ngemva kokungena esitshalweni. 2. Ama-valve adinga ukuhlakazwa ukuze agcinwe kufanele aphansi. 3. Enkambweni yokugcinwa, kuyadingeka ukuhlola ngokucophelela ukuthi ukupakishwa kwengezwe nokuthi i-gland yokupakisha iqinisiwe. 4. Ngaphambi kokufakwa kwe-valve, hlola ukuthi kukhona uthuli, isihlabathi, i-iron oxide nezinye i-sundries ngaphakathi kwe-valve. Uma kukhona okunye kwalokhu okungenhla, kufanele kuhlanzwe ngaphambi kokufakwa. 5. Wonke ama-valve kufanele afakwe i-gasket yebanga elihambisanayo ngaphambi kokufakwa. 6. Uma ufaka umnyango we-flange, izinsimbi kufanele ziqiniswe. Lapho uqinisa amabhawodi e-flange, kufanele aqiniswe ngendlela elinganayo ngokushintshana. 7. Ngesikhathi sokufakwa kwe-valve, wonke ama-valve kufanele afakwe ngendlela efanele ngokuvumelana nesistimu nokucindezela, futhi ukufakwa okungahleliwe nokuxubile akuvunyelwe ngokuqinile. Wonke ama-valve kufanele abalwe futhi aqoshwe ngokohlelo ngaphambi kokufakwa. II Izinyathelo zokuphepha zokuvuza kwamalahle agayiwe. 1. Wonke ama-flange kufanele afakwe nezinto zokuvala. 2. Izindawo ezivame ukuvuza impushana ivalvu yamalahle endaweni yokungena nokuphuma kwe-pulverizer, okokuphakela kwamalahle, i-flange yomkhiqizi, nazo zonke izingxenye ezixhumeke nge-flange. Ngenxa yalesi sizathu, zonke izingxenye zemishini yabo bonke abakhiqizi abazimisele ukuvuza impushana kufanele zihlolwe ngokuphelele, futhi lezo ezingenazo izinto zokuvala zizokwengezwa kabili, futhi izinsimbi zizoqiniswa. 3. Lezi zinyathelo ezilandelayo zizothathwa zokuvuza kwamalahle agayiwe lapho kuhlangana khona ipayipi lamalahle eligayiwe. 3.1 Ngaphambi kokushisela, indawo yokushisela kufanele ipholishwe ngokucophelela ibe yi-metallic luster kanye ne-groove edingekayo ukuze kushiselwe. 3.2 ngaphambi kwelunga le-butt, imvume yejoyinti le-butt kufanele igcinwe futhi ilunga le-butt eliphoqelelwe linqatshelwe ngokuphelele. 3.3 izinto zokushisela kufanele zisetshenziswe ngendlela efanele, futhi ukushisa kuqala kufanele kwenziwe njengoba kudingekile esimweni sezulu esibandayo. III Izinyathelo zokuvimbela ukuvuza kwesistimu kawoyela kanye nokuvuza kukawoyela. 1. Ngesikhathi sokufakwa kwepayipi likawoyela, wonke amalunga e-flange noma amajoyinti enyunyana anentambo yesikulufu kufanele afakwe iphedi lenjoloba elimelana nowoyela noma iphedi ye-asbestos emelana nowoyela. 2. Amaphuzu okuvuza kwesistimu kawoyela agxile kakhulu ku-flange futhi ahlanganiswe nentambo, ngakho-ke amabhawodi kufanele aqiniswe ngokulinganayo lapho ufaka i-flange. Vimbela ukuvuza noma ukuxega. 3. Ngenqubo yokuhlunga amafutha, izisebenzi zesondlo kufanele zihlale zinamathele emsebenzini, futhi zivinjelwe ngokuqinile ukushiya okuthunyelwe bese ziwela okuthunyelwe. 4. Misa isihlungi samafutha ngaphambi kokushintsha iphepha lokuhlunga uwoyela. 5. Lapho ufaka ipayipi lesikhashana lokuxhuma isihlungi sikawoyela (ipayipi lepulasitiki elibonisa amandla aphezulu), ijoyinti kufanele liboshwe ngokuqinile ngocingo lomthofu ukuvimbela uwoyela ukuthi ungagxumi ngemva kokuba isisefo sikawoyela sisebenza isikhathi eside. IV. vimbela okokusebenza kanye nezixhumi zamapayipi ekukhihlizeni amagwebu, ekukhipheni, ekuconseni nasekuvuzeni, ngalezi zinyathelo zokuvimbela ezilandelayo: Ukuze kufakwe uphawu lwe-flange gasket ngaphezu kwe-1.2.5mpa, kuzosetshenziswa i-gasket ejikajikayo yensimbi. I-2.1.0mpa-2.5mpa flange gasket izoba yi-asbestos gasket futhi ipendwe ngempushana yomthofu emnyama. 3.1.0mpa ipayipi lamanzi le-flange gasket lizoba yi-gasket yerabha futhi lipendwe ngempushana yomthofu emnyama. 4. Ukupakishwa kwepompo lamanzi kuzoba ukupakisha okuyinhlanganisela yeTeflon. 5. Intambo ye-asbestos esetshenziswa ezingxenyeni zokuvala zentuthu namapayipi omoya wamalahle kufanele isongwe futhi yengezwe endaweni ehlangene kahle ngesikhathi esisodwa. Akuvunyelwe ngokuphelele ukuyengeza ngamandla ngemva kokuqinisa izikulufu. V. kumele kuthathwe izinyathelo ezilandelayo ukuqeda ukuvuza kwangaphakathi kwevalvu: (lezi zinyathelo ezilandelayo zizothathwa ukuvimbela ukuvuza kwevalvu) 1. Faka ipayipi, hlanza isikali se-iron oxide kanye nodonga lwangaphakathi lwepayipi ngaphandle kwama-sundries, futhi uqinisekise ukuthi udonga lwangaphakathi lwepayipi luhlanzekile. 2. Qinisekisa ukuthi ama-valve angena endaweni kufanele ahlolwe ngo-100% we-hydrostatic. 3. Wonke ama-valve (ngaphandle kwe-inlet) azohlakazwa ukuze ahlolwe, agaywe futhi agcinwe kahle, futhi amarekhodi namamaki azokwenziwa ukuze kulandeleke. Amavalvu abalulekile azofakwa ohlwini ngokuningiliziwe ukuze amukelwe okwesibili, ukuze ahlangabezane nezidingo "zokugxiviza, ukuhlola nokuqopha". ❖ uma igejiwe, ngani? (1) ukuthintana phakathi kwezingxenye zokuvula nokuvala kanye nezindawo ezimbili zokuvala zesihlalo sevalvu; (2) indawo efanelekile yokupakisha, isiqu kanye nebhokisi lokugxusha; (3) ukuxhumana phakathi kwe-valve yomzimba kanye nebhonethi Ukuvuza kwangaphambili kubizwa ngokuthi ukuvuza kwangaphakathi, okusho ukuthi, i-valve ayivalwanga ngokuqinile, okuzophazamisa ikhono le-valve ukusika into ephakathi. Ukuvuza okubili kokugcina kubizwa ngokuthi ukuvuza, okungukuthi, ukuvuza okuphakathi nendawo kusuka ngaphakathi kuya ngaphandle kwevalvu. Ukuvuza kuzodala ukulahleka kwempahla, ukungcoliswa kwemvelo ngisho nezingozi.
