Kuiswa kwekuchengetedza uye kushanda kwekushanda kweanticorrosive fluorine plastic valve Chii chinofanira kucherechedzwa pakugadzwa kweriquefied gasi vharafu Anticorrosive fluorine lined plastic pombi pombi inodzivirira kupisa inowanzoshandiswa pakufambisa zvinwiwa zvinoparadza zvakaita seasidhi, alkali nemunyu. Panguva imwecheteyo, kana uchishandisa fluorine lined pombi, pombi yevharuvhu yekubatanidza inofanirawo kuva anticorrosive. Chii chinoda kutariswa mukuita kwesevhisi uye kuisirwa fluorine lined epurasitiki valve? Kusarudzwa zvine musoro uye kushandiswa kweiyo lining fluorine epurasitiki anti-corrosion vharafu, munhu wese CRES mudambudziko reinjiniya, fluorine epurasitiki anticorrosive pombi uye vharafu mupetroleum, indasitiri yemakemikari, mushonga, simbi, magetsi emagetsi maindasitiri akasimba ekuora senge acid-base yekubata mudziyo. yakashandiswa, asi kuti ungasarudza sei zvakanaka, ine yakanaka lining fluorine epurasitiki mavharuvhu, maererano vatengi vedu kwemakore akawanda munda chikumbiro ruzivo, Izvi zvinotevera kungwarira zvinofanira kuiswa pamberi kushandiswa svikiro tembiricha, kumanikidzwa, kumanikidzwa musiyano uye zvimwe. mamiriro ezvinhu apo fluorine yakavharidzirwa anti-corrosion valve inosarudzwa: 1, yakavharwa nefluorine plastiki valve inoshandisa mamiriro epakati Mamiriro epakati efluorine akaiswa mupurasitiki valve haafaniri kunge ane zvimedu zvakaoma, makristasi, tsvina, nezvimwewo, kuitira kuti urege kupera fluorine lined plastic layer kana PTFE mabhero evhavha core uye chigaro chevharuvhu mukushanda kwekuvhura nekuvhara. Iyo yepakati ine yakaoma zvimedu, makristasi, tsvina, sarudzo, spool, chigaro chinogona kushandiswa kuHastelloy. 2, yakarongedzwa nefluorine epurasitiki vharafu yepakati tembiricha. Yakaiswa nefluorine epurasitiki vharafu, iyo fluorine purasitiki ndeye F46 (FEP), kushandiswa kwepakati tembiricha haigone kudarika 150 ℃ (yepakati tembiricha inogona kuva 150 ℃ kwenguva pfupi, tembiricha yekushandiswa kwenguva refu inofanira kudzorwa mukati me120 ℃), kana zvisina kudaro. , vharafu yechikamu chega chega F46 iri nyore kupfava, deformation, zvichiita kuti valve yakavharwa, kuputika kukuru. Kana tembiricha yepakati ikashandiswa kwenguva pfupi, tembiricha iri pasi pe180 ° C, uye tembiricha iri pasi pe150 ° C kwenguva yakareba, imwe mhando yefluoroplastic-PFA inogona kusarudzwa, asi iyo PFA fluoroplastic lining inodhura. kupfuura iyo F46 lining mumutengo, uye kusarudzwa kweiyo lining pombi zvinhu zvakafanana. 3, usave neiyo negative pressure. Fluorine yakavharwa epurasitiki vharafu inofanirwa kudzivirira kushandiswa kwekumanikidza kwakashata mupombi, kana paine kumanikidza kwakashata, zviri nyore kukonzera fluorine yakamisikidzwa yepurasitiki layer muvhavhavhavha inosvetwa kunze (dhiramu kunze), kupepeta, zvichitungamira kuvhurika kwevhavha nekuvhara kukundikana. . 4, yakarongedzerwa nefluorine plastiki inodzora vharafu inofanira kunge inoenderana neinoda kuyerera (Cv kukosha) kusarudzwa kwakaringana kwesaizi yevharuvhu. Paunosarudza, kana zvichienderana nekudiwa kwetraffic (Cv) uye mamwe maitiro ehunyanzvi anoverengerwa saizi yevharuvhu inofanira kusarudzwa uye kuvhurwa kwevharuvhu, senge saizi yevharuvhu yakakura kwazvo, zvirokwazvo ichaita kuti vharafu mukuvhurwa kwenguva yakareba. nguva inomhanya, pasi pemamiriro ediki uye epakati kudzvanywa, zviri nyore kugadzira iyo yevhavha yepakati nevharuvhu tsvimbo nekukanganisa kwevezvenhau uye kuita kuti vharuvhu izununguke, Iyo valve yepakati tsvimbo mukati menguva yakareba pasi pesimba, kunyange ichaita kuti valve stem fracture. 5, kudzvanywa, kudzvanywa kwakasiyana kunofanirwa kudzorwa mukati meiyo inobvumidzwa renji. Kunyanya mabhero chisimbiso akaiswa fluorine epurasitiki inodzora vharafu, globe vharafu. Nekuti mabhero anogadzirwa ne tetrafluoric zvinhu, kudzvanywa uye kudzvanywa musiyano wakakura, izvo zvinogona kutungamira nyore kuputika kwemabhero. Bellows seal lined fluorine epurasitiki inodzora vharafu, kushandiswa kwemamiriro ekumanikidza, kudzvanywa kwakakura, kunogona kuchinjirwa kuPTFE kurongedza chisimbiso. LPG kugadzwa kwevharuvhu cherechedza kuti LPG valve ivhavha yekumanikidzirwa yekuisa chisimbiso, saka kana vharuvhu yakavharwa, kumanikidzwa kunofanirwa kuiswa kune disc disc kumanikidza chisimbiso chepamusoro kuti chisadonha. Kana iyo yepakati ichipinda muvharuvhu kubva pasi pe diski, kushorwa kunofanirwa kukundwa nechisimba chekushanda ndiko kukwesha kwesimba rehunde uye kurongedza uye kupinza kunoitwa nekumanikidza kwepakati. Simba rekuvhara valve rakakura kudarika simba rekuvhura valve, saka hupamhi hwevhavha yevhavha yakakura, kana zvisina kudaro kukanganisa kwe stem top bend kuchaitika. Chii chatinofanira kutarisisa kana tichiisa liquefied gas valve? Iyo yepamhepo Xiaobian yevharuvhu ichakupindura iwe. Ivhavha yeLPG ivhavha yekumanikidzirwa yekuisa chisimbiso, saka kana vheji yakavharwa, kumanikidzwa kunofanira kuiswa kune disc kumanikidzira chisimbiso chepamusoro kuti chirege kudonha. Kana iyo yepakati ichipinda muvharuvhu kubva pasi pe diski, kushorwa kunofanirwa kukundwa nechisimba chekushanda ndiko kukwesha kwesimba rehunde uye kurongedza uye kupinza kunoitwa nekumanikidza kwepakati. Simba rekuvhara valve rakakura kudarika simba rekuvhura valve, saka hupamhi hwevhavha yevhavha yakakura, kana zvisina kudaro kukanganisa kwe stem top bend kuchaitika. Chii chatinofanira kutarisisa kana tichiisa liquefied gas valve? Iyo yepamhepo Xiaobian yevharuvhu ichakupindura iwe. Manotsi ekumisikidza uye kuchengetedzwa kweliquefied gasi vharafu: Iyo yezviyo pombi yekumisa vharafu inoshanda neruoko vhiri uye mubato inogona kuiswa chero chinzvimbo mupombi. Handwheel, mubato uye michina yekusimudza hazvibvumidzwe kushandiswa pakusimudza. Kuyerera kwepakati kuchaenderana nekutungamira kwemuseve unoratidzwa pamutumbi wevharuvhu. Liquefied gas valve, inozivikanwawo seyekumira kwegonhi, imhando yevharuvhu inoshandiswa. Inofarirwa nekuti kukweshana pakati penzvimbo yekuisa chisimbiso mukuvhura nekuvhara idiki, inogara kwenguva refu, kureba kwekuvhura hakuna kukura, kuri nyore kugadzira, kugadzirisa kuri nyore, kwete kungokodzera zvepakati uye kuderera kumanikidza, asiwo kwakakodzera. high pressure. Nheyo yekuvhara kwayo ndeyekuvimba nevhavha bar pressure, kuitira kuti valve disc sealing surface uye chigaro chekuisa chisimbiso pamusoro pepedyo, kudzivirira midhiya kuyerera. Iyo LPG valve inongobvumira unidirectional kuyerera kwepakati uye ine kutungamira kana yaiswa. Kureba kwayo kwechimiro chakareba kupfuura gedhi revhavha, panguva imwechete, kupikisa kwemvura kwakakura, kushanda kwenguva refu, kuvimbika kwekuvhara hakuna kusimba. Mavharuvhu eLPG akakamurwa kuita mapoka matatu: akananga kuburikidza, kurudyi Angle uye yakatwasuka kuyerera oblique globe mavharuvhu. Apo iyo LPG valve yakazarurwa, KUSVIRA kureba kwevhavha disc ndeye 25% ~ 30% yezita rezita, uye chiyero chekuyerera chasvika kune yakakura, zvichiratidza kuti valve yasvika panzvimbo yakazaruka zvakakwana. Saka iyo yakazara nzvimbo yakazaruka yevharuvhu yepasi inofanira kutariswa nekurohwa kwevhavha disc.
