1, Nzvimbo yekuvuza uye mamiriro: iyo inobatanidza flange mabhaudhi pamativi ese eDN150 vharafu muviri inodonha.Nekuti iyo flange yekubatanidza gap idiki kwazvo, hazvibviri kubvisa kuvuza nekupinza sealant mugomba.Iyo leakage yepakati is steam, iyo leakage system tembiricha i400 ~ 500 ℃, uye iyo system pressure ndeye 4MPa.
2, Kuisa chisimbiso nzira yekuvaka zvinoenderana nekuongororwa kwemunda kwechikamu chekuvuza, kuti uwane chisimbiso chishoma, iyo yakagadziriswa nzira inoshandiswa kuve nenzvimbo yekuvuza, kugadzira chisimbiso chekuvhara, uye jekiseni sealant kubvisa kubuda.
1. Fixture design
(1) Kutemerwa kwechimiro chekugadzirisa
① Iva nenzvimbo yekuvuza uye isa chisimbiso chivharo pakati pevhavha yemuviri flange uye pombi flange inobatanidza nipple flange.Kuti udzivise kudonha zvakare pakudonha kwegevha pakati pemuviri wevharuvhu uye flange nekuda kwekumanikidza kubata, annular mhango ichaiswa panguva yakasangana pakati pechivharo nekumucheto kwekunze kwevhavha yemuviri flange yeglue jekiseni.
② Munguva yejekiseni yejekiseni yekudzikisa flange, chigadziriso chiri nyore kuchinjisa kudivi rediki dhayamita flange, saka muganho chiyero chemazino kubata mazino chinogamuchirwa.
(2) Iyo dhizaini yekudhirowa uye zviyero zvinoenderana zvechimiro chekuvaka chinoratidzwa mumufananidzo 1.
2. Sealant kusarudzwa uye chipimo chekufungidzira
(1) Iyo sealant ichave txy-18#a sealant zvinoenderana nekupisa kweiyo leakage system uye hunhu hwechikamu chekudonha.Iyo sealant ine yakanakisa tembiricha kuramba, yepakati kuramba uye jekiseni mashandiro ekuita, iri nyore kumisikidza yunifomu uye dense yekuisa chisimbiso chimiro, uye chisimbiso chinogona kuchengetedzwa chakatsiga kwenguva yakareba.
(2) Inofungidzirwa kuti 4.5kg sealant inodiwa kune unilateral leakage point.
3. Kuvaka kushanda
(1) Panguva yekumisikidzwa kwekugadzirisa, nekuda kwekusangana kwezino, dhayamita yemukati yetipi yezino idiki.Panguva yekuisa, madziro ekunze echigadziriso anofanirwa kugogodzwa kutenderedza mhete kuti iparadze magumo ezino uye kusungirira muganho.
(2) Mushure mekuvhiyiwa kwejekiseni remumiririri kwapera, chivharo, muviri wevharuvhu uye flange annular cavity ichaiswa mugomba rekuvharira, uye ipapo jekiseni remumiririri mukati mepakati richaitwa.Iyo jekiseni jekiseni maitiro achave akaenzana, uye teerera kune yekuwedzera jekiseni uye kumanikidza kudzivirira kushushikana kuzorora.
(3) Mushure mekunge chisimbiso charapwa, itisa yemuno yekuwedzera jekiseni uye kudzvanya mushure mekuona kwekuita kudzivirira kuzorora kwekushushikana, wobva wavhara gomba rejekiseni.
