1. Sarudza valve yebasa re cryogenic
Kusarudza vharafu ye cryogenic application inogona kuve yakaoma kwazvo. Vatengi vanofanira kufunga nezvemamiriro ebhodhi uye mufekitari. Uyezve, iwo chaiwo zvimiro zvecryogenic zvinwiwa zvinoda chaiwo mavharuvhu kuita. Kusarudzwa kwakakodzera kunovimbisa kuvimbika kwechirimwa, kuchengetedzwa kwemidziyo, uye kushanda kwakachengeteka. Musika wepasi rose weLNG unoshandisa maviri makuru mavharuvhu dhizaini.
Mushandi anofanira kuderedza saizi kuti achengete tangi regasi diki sezvinobvira. Vanoita izvi kuburikidza neLNG (liquefied natural gas, liquefied natural gas). Nekutonhodza kusvika kunenge gasi rechisikigo rinova mvura. -165 ° C. Pakupisa uku, iyo huru yekuzviparadzanisa valve inofanira kuramba ichishanda
2. Chii chinokanganisa kugadzirwa kwevharuvhu?
Kupisa kune simba rinokosha pakugadzirwa kwevhavha. Semuenzaniso, vashandisi vanogona kuida kune yakakurumbira nharaunda senge Middle East. Kana, inogona kunge yakakodzera nzvimbo dzinotonhora senge polar oceans. Mamiriro ese ari maviri anogona kukanganisa kusimba uye kusimba kwevhavha. Izvo zvinoumba mavharuvhu aya zvinosanganisira muviri wevharuvhu, bhoneti, dzinde, stem seal, bhora vharafu uye chigaro chevharuvhu. Nekuda kwekuumbwa kwezvinhu zvakasiyana, zvikamu izvi zvinowedzera uye chibvumirano patembiricha dzakasiyana.
Cryogenic application sarudzo
Sarudzo yekutanga:
Vashandi vanoshandisa mavharuvhu munzvimbo dzinotonhora, dzakadai semafuta emafuta mugungwa repolar.
Sarudzo 2:
Vashandi vanoshandisa mavharuvhu kugadzirisa zvinwiwa zviri pasi pechando.
Kana iri gasi rinopisa zvikuru, rakadai segasi rechisikigo kana okisijeni, vharuvhu inofanirawo kushanda zvakanaka kana pakaitika moto.
3.Pressure
Pane kuvakwa kwekumanikidza panguva yekubata kwakajairika kwefiriji. Izvi zvinokonzerwa nekuwedzera kupisa kwenharaunda uye kunotevera kuumbwa kwemhepo. Kunyatsotarisirwa kunofanirwa kutorwa paunenge uchigadzira valve / piping system. Izvi zvinobvumira kumanikidzwa kuvaka.
4.Temperature
Kukurumidza kuchinja kwekushisa kunogona kukanganisa kuchengetedzwa kwevashandi nemafekitari. Pamusana pekuumbwa kwezvinhu zvakasiyana-siyana uye urefu hwenguva yavanoiswa pasi pefiriji, chikamu chimwe nechimwe che cryogenic valve chinowedzera uye zvibvumirano pamitengo yakasiyana.
Imwe dambudziko guru pakubata mafiriji ndiko kuwedzera kwekupisa kubva munzvimbo yakapoteredza. Uku kuwedzera kwekupisa ndiko kunokonzera kuti vagadziri vaparadzanise mavharuvhu nemapombi
Mukuwedzera kune yakakwirira yekushisa, valve inofanirawo kusangana nematambudziko makuru. Kune liquefied helium, tembiricha yegasi yakanyungudutswa inodonha kusvika -270 ° C.
5.Function
Sezvineiwo, kana tembiricha yadonha kusvika pa zero, basa revharuvhu rinova rakaoma kwazvo. Mavharuvhu eCryogenic anobatanidza mapaipi nemagasi emvura kune zvakatipoteredza. Inoita izvi pane ambient tembiricha. Mhedzisiro yacho inogona kuve musiyano wetembiricha unosvika 300 ° C pakati pepombi nenzvimbo.
6.Kubudirira
Musiyano wetembiricha unogadzira kuyerera kwekupisa kubva kunzvimbo inodziya kuenda kunzvimbo inotonhora. Ichakuvadza basa rakajairika revhavha. Inoderedzawo kushanda kwegadziriro mumamiriro ezvinhu akaoma. Izvi zvinonyanya kunetsa kana mazaya echando achiita pamucheto unodziya.
Nekudaro, mune yakaderera tembiricha maapplication, iyi passive yekudziya maitiro zvakare nemaune. Iyi nzira inoshandiswa kuvhara chivharo chevhavha. Kazhinji, tsinde yevhavha yakavharwa nepurasitiki. Zvinhu izvi hazvigoni kumira kutonhora kwakadzika, asi zvisimbiso zvesimbi zvepamusoro-soro zvezvikamu zviviri, izvo zvinofamba zvakawanda zvakatarisana, zvinongodhura zvakanyanya uye zvinenge zvisingaiti.
7.Kuisa chisimbiso
Pane mhinduro iri nyore kudambudziko iri! Iwe unouya nepurasitiki inoshandiswa kuvhara hunde yevharuvhu kune imwe nzvimbo iyo tembiricha inenge yakajairika. Izvi zvinoreva kuti chisimbiso chevhavha hunde inofanira kuchengetedzwa kure kubva mumvura.
8.Three offset rotary tight isolation valve
Izvi zvinogadzirisa zvinobvumira valve kuvhura uye kuvhara. Vane kukweshera kushoma uye kukweshana panguva yekushanda. Iyo inoshandisawo stem torque kuita kuti valve iwedzere kusimba. Rimwe rematambudziko ekuchengetwa kweLNG rakavharirwa makomba. Mumakomba aya, mvura inogona kuzvimba zvakanyanyisa kanopfuura ka600. Iyo mitatu-inotenderera yakasimba yekuzviparadzanisa valve inobvisa dambudziko iri.
9.Single uye kaviri baffle cheki mavharuvhu
Aya mavharuvhu chinhu chakakosha mumidziyo yekunyungudutsa nekuti anodzivirira kukuvadzwa kunokonzerwa nereverse kuyerera. Material uye saizi zvakakosha kufunga nekuti cryogenic mavharuvhu anodhura. Migumisiro yevhavha isina kururama inogona kukuvadza.
Mainjiniya anovimbisa sei kusimba kwemavharuvhu e cryogenic?
Kudonhedza kunodhura zvakanyanya kana munhu akafunga mutengo wekutanga kugadzira gasi mufiriji. Zvine ngozi zvakare.
Dambudziko hombe neiyo cryogenic tekinoroji mukana wekudonha kwechigaro chevharuvhu. Vatengi vanowanzo koshesa kukura kweradial uye mutsara wehunde maererano nemuviri. Kana vatengi vakasarudza valve yakarurama, vanogona kudzivisa matambudziko ari pamusoro apa.
Kambani yedu inokurudzira kushandisa yakaderera tembiricha mavharuvhu akagadzirwa Stainless simbi. Panguva yekushanda ne liquefied gasi, zvinhu zvinopindura zvakanaka kune tembiricha gradients. Mavharuvhu eCryogenic anofanirwa kushandisa zvisimbiso zvakakodzera zvine kusimba kunosvika ku100 bar. Pamusoro pezvo, kutambanudza bhoneti chinhu chakakosha zvikuru nekuti chinotarisisa kusimba kwe stem sealant.
