Nhanganyaya kune Bellow Seed mavharuvhu

Bellow(s) Chisimbiso(ed) Mavharuvhu

Kudonha panzvimbo dzakasiyana-siyana mumapaipi anowanikwa mumiti yemakemikari kunounza kuburitsa. Ese mapoinzi ekuvuza akadai anogona kuwonekwa uchishandisa nzira dzakasiyana uye zviridzwa uye zvinofanirwa kucherechedzwa neinjiniya yechirimwa. Yakakosha leakage point inosanganisira flanged gasket majoini uye iyo Valve / pombi gland kurongedza, etc. Nhasi indasitiri yemakemikari process iri kuzvigadzirira yakanangana yakachengeteka tekinoroji yekuchengetedza nharaunda uye rave basa rese reinjiniya rekugadzira zvirimwa zvinomisa kukuvadza kune nharaunda kuburikidza. kudzivirira kubuda kwechero makemikari ane chepfu.

Kubuda kubva kuValve gland kana stuffing boxkazhinji inyaya yekutarisira kana mainjiniya ekudyara. Kubuda uku kunoreva:
a) Kurasika kwezvinhu b) Kusvibiswa kwemhepo c) Kune ngozi kune vashandi vemiti.

Semuenzaniso, tora nyaya yekudonha kwemhepo kuburikidza neValve gland. Pa150 PSI, kubvumidzwa kwe 0.001 chete ″ kuburikidza negland kunoreva kudonha pamwero we25 lb/awa. Izvi zvakaenzana nekurasikirwa kweUSD 1.2 pashift yeawa masere, kana USD 1,100 pagore. Saizvozvo, kadonhwe diki ke 0.4 mm dhayamita pasekondi imwe chete inoguma mukuraswa kwemarita 200 pagore yemafuta anodhura kana zvinonyungudutsa. Uku kudonha kunogona kuderedzwa zvakanyanya nekushandisa bellow chisimbiso Valve. Chinyorwa chino chave kuzotarisa kuvakwa uye kushanda kwechisimbiso chakavhuvhuta.

Kuvakwa kwepasi

Iyo bellow cartridge yakasungirirwa kune ese ari maviri Bonnet yeValve uye iyo Valve stem. Iyo bellow cartridge ine akati wandei maconvolutions uye aya maconvolutions anova akamanikidzwa kana kuwedzerwa zvichienderana nekufamba kweValve stem. (Nezvesainzi, bhero rinomanikidzwa kana Valve iri munzvimbo yakavhurika uye inowedzerwa kana Valve iri munzvimbo yakavharwa). Zvakakosha kuisa zvakanaka miviri yeValve. Iyo bhero inogona kuvharirwa kune mavhavha munzira mbiri dzakasiyana. Chekutanga, iyo bellow inogona kusungirirwa kune Yevhavha hunde kumusoro uye iyo Valve muviri pazasi. Muchiitiko ichi muitiro fluid iri mukati bhero kana yechipiri nzira bhero ari welded kuti Valve hunde pazasi uye muviri pamusoro. Muchiitiko ichi iyo nzira yemvura inowanikwa munharaunda yeannular pakati peValve Bonnet uye bellow (kubva kunze).

Iyo bhero chinhu chakakosha uye inoumba moyo webellow chisimbiso Mavhavha. Kuti udzivise kumonyoroka kwebhero, Valve inofanirwa kunge iine dzinde rine mutsara wekufamba chete. Izvi zvinogona kuwanikwa uchishandisa inonzi sleeve-nut paJoko chikamu cheValve Bonnet. Whiri remaoko rakaiswa pane sleeve-nati iro rinonyatso fambisa kutenderera kwevhiri reruoko kuita mutsetse wekufamba muValve hunde.

Bellow types

Kune mhando mbiri huru dzebhero: iyo Forged Bellow uye iyo Welded Bellow. Mavhuvhu akaumbwa anogadzirwa kubva pakumoneredza shizha rakati sandara (mapepa akatetepa emadziro) achiisa muchubhu inozobatanidzwa nekureba. Iyi chubhu inozobva yaumbwa iine mechanically kana hydrostatically kuita bellow ine yakatenderedzwa uye yakapetana zvakafara. Iyo welded yemhando yeshizha bellow inogadzirwa newelding-senge mahwendefa esimbi yakatetepa pamwe chete mukati nekunze kwedenderedzwa remawachi - semahwendefa. A welded leaf bellow ine mapete akawanda paurefu hweyuniti kana zvichienzaniswa nemabhero akafodhi. Saka, pakureba kwakafanana kwesitiroko, mabhero akafukidzwa akareba zvakapetwa kaviri kana katatu pane mamwe mashizha akasonwa.

Sezvineiwo, mavhuvhu akagadzirwa nemuchina anokundikana pane chero nzvimbo, ukuwo shizha rakasungwa rinowanzotadza kushanda kana pedyo neweld. Kuti ive nechokwadi chekupinda kwakazara kwebellow ends uye kupera coller welding zvinokurudzirwa kugadzira uchishandisa micro plasma welding.

Bellow dhizaini

Iyo yakawanda-ply bellow dhizaini inosarudzwa pakubata yakakwira kudzvanywa mvura (kazhinji maviri kana matatu plies emadziro esimbi). A ply ply bellow inogona kuwedzera kudzvanywa kwayo ne 80% kusvika 100% kana ichienzaniswa ne ply bhobho rehukobvu hwakafanana. Nerumwewo, kana pfumbu rimwechete rehukobvu hwakaenzana nechiyero chekumanikidza che ply ply mbiri ikashandiswa, kureba kwesitiroko kunoderedzwa. Nekudaro, iyo yakawanda-ply bellow dhizaini inopa mukana wakasiyana pane imwechete ply bellow. Zviri pachena kuti bhero iri pasi pekuneta kwesimbi uye kuneta uku kunogona kukonzera weld kutadza. Hupenyu hwekuneta hunokonzerwa nezvinhu zvekuvaka, nzira yekugadzira, kureba kwekurova uye sitiroko frequency, mukuwedzera kune akajairwa paramita senge tembiricha yemvura uye kudzvanywa.

Bellow zvinhu

Iyo inonyanya kufarirwa simbi isina simbi bellow zvinhu ndeye AISI 316Ti iyo ine Titanium kutsungirira kupisa kwakanyanya. Neimwe nzira, Inconel 600 kana Inconel 625 inovandudza simba rekuneta uye kusaita ngura kana zvichienzaniswa nesimbi isina tsvina. Saizvozvowo, Hastalloy C-276 inopa hukuru hwekudzivirira uye kuneta simba kupfuura Inconel 625. Kuramba kuneta kunogona kuvandudzwa nekushandisa mabhero akawanda uye kuderedza urefu hwesitiroko; izvi zvinogona kuwedzera zvakanyanya hupenyu hwesevhisi.

Sarudzo dzevharuvhu

Mhando dzakawanda dzeValve dzinofanirwa kuiswa zvisimbiso zvisimbiso ndeye gedhi uye magadzirirwo eglobe (ona Mufananidzo 1) .Idzi dzakanyatsokodzera kushandiswa nemabhero nekuda kwekuvakwa kwemukati uye axial kufamba kwehunde yeValve.
Zvichienderana neruzivo rwuripo, zvinoita sekunge ikozvino bellow chisimbiso Mavhavha anosiyana muhukuru kubva pa3 mm NB kusvika 650 mm NB. Kudzvanya ratings inowanikwa kubva ANSI 150 # kusvika 2500 #. Sarudzo dzezvinhu zveMavharuvhu dzinosanganisira kabhoni simbi, simbi isina tsvina uye exotic alloys.

Applications

Heat Transfer media: oiri inopisa inowanzoshandiswa mumaindasitiri senge synthetic fibers / POY (Partially Oriented Yarn). Zvisinei, pane nguva dzose njodzi yemoto nekuda kwekupisa kwemafuta anopisa pamakemikari anopisa zvikuru. Pano, bellow chisimbiso Mavhavha anogona kumisa kuvuza.

Vacuum / ultra high vacuum: mamwe maapplication anoda vacuum pombi kuti irambe ichiburitsa mweya kubva papombi. Chero mavharuvhu akajairwa akaiswa papombi anogona kubvumira mweya wekunze kuti upinde mupombi zvakakwana mubhokisi rekuisa bhokisi. Saka iyo bellow chisimbiso Valve ndiyo yega mhinduro yekudzivirira mweya kubva kupfuura nepakati pebhokisi rekuisa.
Zvinwiwa zvine njodzi zvakanyanya: kune midhiya senge chlorine (ona Mufananidzo 2), hydrogen, ammonia uye phosgene, bellow chisimbiso Valve idhizaini yakanaka sezvo kuvuza kuburikidza negland kuchibviswa zvachose.
Nuclear chirimwa, chinorema mvura chirimwa: mune zviitiko apo kubuda kwemwaranzi kunofanirwa kudzivirirwa nguva dzese, iyo bellow seal Valve ndiyo yekupedzisira sarudzo.
Mvura inodhura: mune mamwe maapplication kudonha kunoda kudzivirirwa nekuda kwekudhura kwemvura. Pano, kuongororwa kwehupfumi kunowanzofarira kushandiswa kwebellow seal Valves.
Mamiriro ezvakatipoteredza: kutenderera pasirese, zviyero zvine chekuita nekubuda uye nharaunda zviri kuwedzera kuomarara zuva nezuva. Saka zvinogona kunetsa kuti makambani awedzere mukati mezvivakwa zviripo. Nekushandiswa kwebellow seal Valves, kuwedzera pasina kuwedzera kwezvakatipoteredza
kukanganisa kunogoneka.
