Chengetedzo vharafu yaiwanzosangana nekukanganisa kutonga uye kugadzirisa fluorine lining valve kushandisa mirayiridzo
Vavhavha yekuchengetedza kazhinji yakasangana nekukanganisa kutonga uye kugadzirisa
1. Usavhura kana kudzvanywa kwataurwa
Chikonzero chemamiriro ezvinhu aya ndechokuti kudzvinyirirwa nguva dzose hakuna kururama. Kutsikirirwa kwechitubu kana nzvimbo yesando inofanira kugadziriswa; Diski rinonamira pachigaro. Ivhavha yekudzivirira inofanira kunge iri nguva dzose yemhepo yemhepo kana mvura yekuedza; Lever mhando yekuchengetedza vharafu lever yakanamatira kana inorema sando inofambiswa. Huremu hunofanira kugadziriswa uye lever inofanira kufamba zvakasununguka.
2, isingasviki kudzvanywa kwakatarwa kuvhurika
Kudzvinyirira kukuru hakuna kururama; Spring kuchembera chitubu elasticity inoderera. Iyo screwing screw kana chitubu chinofanira kusimbiswa zvakanaka.
3. Iyo disc haidzokeri kuchigaro mushure mekubuda
Izvi zvinonyanya kukonzerwa nechitubu bending stem, disc yekuisa chinzvimbo haina kunaka kana kunamatira. Inofanira kubatanidzwazve.
4, disc frequency kusvetuka kana vibration
Chikonzero chikuru ndechekuti kuomarara kwechirimo kwakakurisa. Chitubu chine kuoma kwakakodzera chinofanira kushandiswa panzvimbo; Denderedzwa rekugadzirisa harina kunyatsogadziriswa, kuitira kuti kumanikidzwa kwakanyanya. Nzvimbo yemhete yekugadzirisa inofanira kugadziriswa; Kupokana kwepombi yekuburitsa kwakakura zvakanyanya, zvichikonzera kuburitsa kwakawandisa kumashure. Kurasa pombi kuramba kunofanira kuderedzwa.
5. Dzvinyiriro inoramba ichikwira mushure mekupera simba
Izvi zvinonyanya kukonzerwa nekuti kusarudzwa kwevhavhavhavhavhavhavhavhavhavhavhavhavharunosiya Xiaoping midziyo kuchengeteka kusunungurwa,inofanira kusarudzwa zvakare zvakakodzera vharafu vharafu; Stem pakati mutsara kana chitubu ngura, kuitira kuti dhisiki haigoni kuvhurwa kuhurefu hwakakodzera, inofanira kubatanidza hunde kana kutsiva chitubu; Kana pombi yepombi yakachekwa isina kukwana, pombi yekuburitsa inoenderana nenzvimbo yakachengeteka yekuburitsa inofanira kutorwa.
6, kuvuza
Pasi pesimba rinowanzoshanda remidziyo, kuvuza pakati pe disc uye chisimbiso pamusoro pechigaro chinodarika dhigirii inobvumirwa. Chikonzero ndechekuti: pane tsvina pakati pevhavha disc uye chisimbiso pamusoro pechigaro. Inogona kushandisa chipanera chekusimudza kuvhura vharuvhu kakawanda, tsvina yakashambidzwa; Kukuvadza kwekuisa chisimbiso pamusoro. Inofanira kugadziriswa nekukuya kana kukuya mushure mekutendeuka maererano nehuwandu hwekukuvadza. Stem bending, tilting, kana lever uye fulcrum deflection, zvichikonzera spool uye disc misalignment. Inofanira kusanganiswa kana kutsiviwa; Muchirimo elasticity inodzikira kana kurasikirwa nekusimba. Matanho akadai sekutsiva chitubu uye kugadzirisa kudzvanya kwekuvhura kunofanirwa kutorwa.
Mirayiridzo yekushandisa fluorine lined valves
Hunhu hunokosha hwefluorine lined valve:
Kutanga, fluorine yakavharwa vharafu kemikari kuita:
Atmospheric aging resistance: radiation resistance and low permeability: kuratidzwa kwenguva refu kumhepo, pamusoro uye zvinhu zvinoramba zvisina kushanduka.
Incombustibility: oksijeni muganho index pazasi 90.
Acid uye alkaline kuramba: isinganyunguriki mune yakasimba asidhi, mabhesi uye organic solvents.
Oxidation resistance: kusaita ngura nemaokisijeni akasimba.
Zviviri, fluorine lined valve kushanda maitiro:
Performance: Medium kushanda tembiricha: -100 ℃ ~ -150 ℃
Kumanikidza kwepakati pekushanda: kudzvanywa kwakanaka: 2.5mpa, kumanikidza kwakashata pane tembiricha yekamuri 70KPa
Corrosion resistance: simbi PTFE inoumba pombi, kuwedzera kune yakanyungudutswa simbi lithium, potassium, sodium, chlorine trifluoride, okisijeni trifluoride pakupisa kwepamusoro, kuyerera kwakanyanya kwemvura fluorine, inogona kuramba inenge yese makemikari media, kusanganisira concentrated nitric acid uye aqua royalty corrosion. , inogona kushanda mukupisa kwe230℃-250℃ kwenguva yakareba. Simbi polyvinylidene fluoride kana imwe vinylidene fluoride composite pombi, halogen, halogenated hydrocarbons, yakasimba oxidants, boiling acid, alkali, akasiyana organic solvents ane yakanaka corrosion resistance, asi isingamiri kusvuta sulfuric acid, concentrated hot sulfuric acid uye nitric acid, ketoni. , esters, amines uye yakanyanya tembiricha sulfonating agent corrosion pamusoro pe90 ℃.
Izvo zvakakosha zve fluorine lined valve:
High tembiricha inodzivirira kushanda tembiricha kusvika 250 ℃
Kuderera kwekushisa kwepasi nekuoma kwema mechanical; Kunyangwe tembiricha ikadonha kusvika -196 ℃, kureba kwe5% kunogona kuchengetedzwa.
Corrosion resistance kune akawanda makemikari uye zvinonyungudutsa, zvichiratidza inertia, asidhi yakasimba uye alkali, mvura uye zvakasiyana siyana zveorganic solvents.
Mamiriro ekunze anoshingirira nehupenyu hwekuchembera mumapurasitiki.
High lubrication ndiyo yakaderera friction coefficient mune yakasimba zvinhu.
Kusina-kunamatira ndiko kuderera kwepasi tension mumidziyo yakasimba, hainamati chero chinhu.
Isiri-chepfu ine physiological inertia, isiri-chepfu kune zvipenyu.
Fluorine lined valve main applications:
Fluorine LINED VALVE YAKAKODZERA Kupisa kwepamusoro kunotyisa gasi uye mvura, mamwe marudzi esimbi epurasitiki inoumbwa pombi uye simbi pombi haina kukodzera kutakura svikiro, simbi PTFE yakaoma. Iyo simbi polyvinylidene fluoride composite pombi yakakodzera kuendesa corrosive media ine tembiricha yekushanda kubva -40 ℃ kusvika +150 ℃.
Fluorine lining valve processing tekinoroji sumo
A, tetrafluoroethylene (PTFE) - sodium naphthalene mhinduro yekurapa bonding nzira
Polytetrafluoroethylene (PTFE) - sodium naphthalene solution yekurapa bonding nzira: sodium naphthalene solution kurapwa kwefluorine ine zvinhu, kunyanya kuburikidza necorrosion liquid uye PTFE plastic chemical reaction, kubvarura chikamu chemaatomu efluorine pamusoro pechinhu, saka kumusoro kuruboshwe. a carbonized layer uye mamwe mapoka epolar. Infrared spectrum inoratidza kuti kuiswa kweboka re hydroxyl, boka re carbonyl uye unsaturated bond uye mamwe mapoka epolar pamusoro pepamusoro, mapoka aya anogona kuwedzera simba repamusoro, kuderedza kushamwaridzana kweAngle, kuvandudza kunyorova, kubva kune yakaoma kusvika kune inonamira. Iyi ndiyo nzira inonyanya kushanda uye inowanzoshandiswa pakati penzira dzose dzakadzidzwa panguva ino. Sodium naphthalene tetrahydrofuran inowanzoshandiswa senge corrosion solution. Iyo bonding process ndeiyi inotevera:
(1) Kugadzirira kwemhinduro yekurapa: wedzera imwe chiyero chesimbi yesodium mumushonga we tetrahydrofuran uye naphthalene, chikamu chikuru che sodium metal chinodzorwa pa 3% -5%, kusimudzira pakamuri tembiricha kweanenge 2h, kusvika ruvara rwe. mhinduro yacho inoratidzika yakasviba kana yakasviba;
(2) iyo PTFE workpiece inofanira kurapwa yakanyudzwa mumushonga weinenge 5 ~ 10min, uye yakanyura mu ** mhinduro ye3 ~ 5 min;
(3) Bvisa workpiece kubva mumushonga, sukurudza nemvura uye woiisa mumumvuri kuti iome zvakasununguka;
(4) Sarudza epoxy resin, silicone kana polyurethane seanonamira, yakaenzana yakanamirwa panzvimbo yakagadziriswa kuti isungirwe uye isungirwe pakarepo, yakamira pa24 ~ 30 ℃ kwe24h, unogona kusungirira zvakasimba.
