Yakadzika tembiricha vharafu ine refu mutsipa vharafu chivharo zvikonzero yakaderera tembiricha vharafu kusarudzwa kubvunza odha zvinhu zvinoda kutarisirwa
Low tembiricha mavharuvhu anosanganisira yakaderera tembiricha chimbichimbi cut-off vharafu, yakaderera tembiricha kucheka-kure vharafu, yakaderera tembiricha cheki vharafu, LNG yakaderera tembiricha vharafu, NG** yakaderera tembiricha vharafu, etc., rinonyanya kushandiswa 300.000 matani ethylene, liquefied gasi chaiwo. uye imwe makemikari chirimwa. Iyo inobuda mvura yakaderera-kupisa yepakati senge ethylene, yemvura okisijeni, yemvura hydrogen, liquefied gasi rechisikigo, liquefied petroleum zvigadzirwa, nezvimwewo, haingobatike uye inoputika, asiwo gasification kana ichipisa. Kana gasification, vhoriyamu inowedzera mazana enguva.
Zvikonzero zvehuro hurefu hufukidze kune yakaderera tembiricha mavharuvhu
Inokodzera tembiricha yepakati -40 ℃ ~ -196 ℃ vharafu inonzi yakaderera tembiricha vharafu, uye rudzi urwu rwevharuvhu rinowanzo shandisa chivharo chehuro refu.
Ivhavhavha yepasi-tembiricha inosanganisira yakadzika-tembiricha yekucheka-kuvhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha kuwa,yakadzika-tembiricha yekucheka,yakadzika-temperature check valve,LNG yakadzika-temperature valve,NG low-temperature valve, etc.,inonyanya kushandiswa mu300,000 tons of ethylene, liquefied gasi rechisikigo uye mamwe makemikari chirimwa. Iyo inobuda mvura yakaderera-kupisa yepakati senge ethylene, yemvura okisijeni, yemvura hydrogen, liquefied gasi rechisikigo, liquefied petroleum zvigadzirwa, nezvimwewo, haingobatike uye inoputika, asiwo gasification kana ichipisa. Kana gasification, vhoriyamu inowedzera mazana enguva
Iyo refu yehuro inovhara inotsanangurwa nekuti:
(1) Iyo yakareba yevhavha yevhavha yevhavha ine basa rekudzivirira yakadzika tembiricha yevhavha yekutakura bhokisi, nekuti kuisirwa chisimbiso chebhokisi rekurongedza ndeimwe kiyi yeyakadzika tembiricha vharafu. Kana bhokisi rekuisa rikadonhedza, rinoderedza kutonhora mhedzisiro uye kutungamira kune gasification ye liquefied gasi. Pakupisa kwakadzika, nekudzikira kwekushisa, kunyungudika kwekutakura kunopera zvishoma nezvishoma, uye kuburitsa-chiratidzo kuita kunoderera. Nekuda kwekudonha kwe media, kurongedza uye tsinde yevharuvhu yakaomeswa nechando, izvo zvinokanganisa kushanda kwakajairwa kwehunde yevharuvhu. Panguva imwecheteyo, iyo pulp kurongedza inokwenya nekuda kwekufamba kwevharuvhu hunde kumusoro nekudzika, zvichikonzera kudonha kwakanyanya. Naizvozvo, zvinodikanwa kuve nechokwadi kuti tembiricha yepasi pekuzadza iri pamusoro pe8 ℃.
(2) Iyo yakareba yemutsipa yevhavha yekuvhara chimiro iri nyore kuputira iyo inotonhora inochengetedza zvinhu kudzivirira kutonhora kwesimba kurasikirwa kweiyo yakaderera tembiricha vharafu.
(3) Iyo yakareba mutsipa chimiro cheyakadzika tembiricha vharafu inogonesa kukurumidza kutsiviwa kwezvikamu zvikuru zvevharuvhu kuburikidza nekubviswa kwevhavhavhavha. Sezvo maitiro mapaipi uye mavharuvhu muchikamu chinotonhora chemidziyo kazhinji akaiswa mu'bhokisi rinotonhora', iyo refu yemutsipa chivharo chivharo chinogona kukwidziridzwa kuburikidza ne'bhokisi rinotonhora' madziro. KUTI UCHINZE VALVE MAIN chikamu, ingo bvisa kuburikidza nevhavhavhavhavhavha, pasina kubvisa muviri. Muviri wevharuvhu uye pombi zvakasungirirwa mune imwe, nepazvinobvira kudzikisa kubuda kwebhokisi rinotonhora, kuve nechokwadi chekuvharwa kwevhavha.
Yakaderera tembiricha vharafu sarudzo yekubvunza kurongeka zvinhu zvinoda kutariswa
Low tembiricha vharafu inoreva vharafu inogona kushandiswa pasi yakaderera tembiricha mamiriro. Kazhinji, vharafu ine tembiricha yekushanda yakaderera pane -40 ℃ inonzi yakaderera tembiricha vharafu. Yakadzika tembiricha vharafu ndechimwe chezvinhu zvakakosha zvakakosha muindasitiri yepetrochemical, kupatsanurwa kwemhepo, gasi rechisikigo uye mamwe maindasitiri. Hunhu hwayo hunosarudza kana inogona kugadzirwa zvakachengeteka, zvine hupfumi uye zvakachengetedzeka. Nekuvandudzwa kwemichina yemazuva ano, kushandiswa kwevhavha yekushisa kwakadzika kunowedzera uye kwakafara, kudiwa kunowedzerawo uye kwakakura.
Kune tembiricha yakakwira kupfuura -50 ℃, kazhinji usashandise iyo yakareba mutsipa chimiro, kune tembiricha pazasi -50 ℃ bhora vharafu, mutsipa kureba T zvinoenderana nekugadzira uye kuverenga kweYijie valve kambani. Yakadzika tembiricha bhora vharafu inonyanya kushandiswa kuburitsa yemvura yakadzika tembiricha midhiya senge ethylene, liquid okisijeni, liquid hydrogen, liquefied gasi rechisikigo, liquefied petroleum zvigadzirwa, nezvimwewo, kwete chete zvinopisa uye zvinoputika, asiwo mukupisa kune gasification, gasification. , kuwedzera kwevhoriyamu kane mazana.
Izvo zvinhu zvakanyungudutswa zvegasi vharafu zvakakosha zvakanyanya, izvo zvinhu hazvina kukodzera, zvinokonzeresa goko uye chisimbiso chepamusoro kuvuza kana kuvuza; Iyo yakazara mechanical properties, simba uye simbi yezvikamu hazvigoni kusangana nezvinodiwa zvekushandisa kana kunyange kuputsika. Zvinokonzera kuti liquefied natural gas medium leakage. Naizvozvo, mukugadzira, kugadzira uye kugadzira liquefied gasi mavharuvhu, zvinhu ndiyo yekutanga uye yakakosha nyaya. Muviri wevharuvhu uye chivharo chinotora: LCB(-46 ℃), LC3(-101℃), CF8(304)(-196℃).
Yakadzika tembiricha vharafu inoda kushandisa refu mutsipa vharafu chivharo chimiro, zuva rayo nderekuderedza kunze kunouya kupisa mumudziyo; Ita shuwa kuti tembiricha yebhokisi rekutakura iri pamusoro pe0 ℃, kuitira kuti kurongedza kugone kushanda zvakajairwa; Dzivirira kutonhora kana kutonhora kwedzinde uye nechepamusoro pebhoneti pane stuffing box chikamu nekuda kwechikamu chebhokisi chekuisa chiri kunyanya kutonhora.
Dhizaini yevhavha yehuro refu yevhavha inonyanya kugadzirwa kwehuro kureba L, L inoreva chinhambwe kubva pasi pebhokisi rekuisa kusvika kumusoro kwechigaro chekuisa chisimbiso, chine chekuita nekupisa kwekupisa kwezvinhu, iyo inopisa conductivity nzvimbo uye pamusoro pekupisa kupisa kwepasi coefficient, nzvimbo yekupisa kupisa uye zvimwe zvinhu, kuverenga kunonyanya kuoma, kazhinji kunowanikwa nenzira yekuedza.
Mamiriro ekushanda evhavha yepasi-yakadzika yakaoma. Zvizhinji zvezvishandiso zvinoshandiswa zvinopisa, zvinoputika uye zvinopinda mukati. Iyo yakaderera kushanda tembiricha inogona kusvika -269 ℃ uye yakanyanya kushanda kumanikidza inogona kusvika 10MPa. Naizvozvo, magadzirirwo, kugadzira uye kuongorora yakaderera tembiricha mavharuvhu zvakasiyana chaizvo kubva universal mavharuvhu.
Vanhu vakawanda, kungoisa vharafu zvinhu yakaderera tembiricha simbi inorangarirwa zvakananga cryogenic mavharuvhu, chaizvoizvo zvikasadaro, chinhu chete cryogenic mavharuvhu semi-apedza zvigadzirwa, nokuti haana pashure cryogenic kurapwa panguva yakaderera tembiricha, uye yakaderera-tembiricha. cryogenic treatment is the nods eyeball pen of cryogenic valves, cryogenic valves in cryogenic treatment ndiyo yakakosha, kuitira kuti uve nechokwadi chokuti mavharuvhu e-cryogenic anosangana nezvinodiwa, Kunyanya iyo coefficient yekuwedzera, haizotungamiri kune zvakasiyana-siyana zvevhavha yakanamatira kushandiswa. . Dzimwe nguva mukufungisisa mutengo wechinetso, unodawo kufunga nezvehutano hwevhavha. Low tembiricha vharafu ivharuvhu inokosha.
Ikozvino mavharuvhu emumba akawanda haasiri mushure mekurapwa kwecryogenic pakudziya kwakaderera, mutengo waizodhura, pano ndinogona kukupa basa rakaoma, kana seti yako yemidziyo ye cryogenic mutengo wakakwira, iyo cryogenic midziyo inodhura, uye cryogenic liquid nitrogen. kuwedzera kune inodiwa zvinhu uye yakashata yekuchengetera svikiro, uye inopedza vharafu mukugadziriswa kwemvura nitrogen yakanyanya, Uye mvura nitrogen haina kudhura. Iyo yakadzika tembiricha vharafu inogadzirwa neyakasarudzika yakadzika tembiricha kurapwa, yakaomarara machining mativi munzvimbo inotonhorera kwemaawa mashoma (2-8 maawa), kuburitsa kushushikana, kuve nechokwadi chekuita kwakadzika tembiricha yechinhu, kuve nechokwadi chekupedzisa saizi, kudzivirira vharafu mumamiriro ekushisa akadzika, nekuda kwekushanduka kwekushisa kunokonzerwa nekugadzirisa kunokonzerwa nekudonha kwevhavha yekushisa.
Yakaderera tembiricha yevharuvhu sarudzo yekubvunza odha zvinhu zvinoda kutariswa:
Kuti uite iyo cryogenic valve zviri nani kusangana nezvinodiwa nemutengi, kana iwe uchida cryogenic valve, ndapota ipa iyo chaiyo paramita yaunoziva.
1. Zita rezasi tembiricha yepakati;
2. Tembiricha yepakati tembiricha yepakati;
3. Unoda kugadzirisa urefu hwemutsipa wakareba wevhavha yekushisa yakadzika, iyo isina kupiwa maererano nehuwandu hwevhavha;
4. Zvinhu zvevhavha yekushisa yakadzika (inogona kugadzirwa maererano nezvinodiwa nevatengi);
5. Low tembiricha vharafu pressure;
6. Low tembiricha vharafu chisimbiso (soft chisimbiso kana yakaoma chisimbiso);
7. Connection mode (flange connection kana welding);
8. Dhiraivha mode (manual, pneumatic, magetsi).
