1. Nhanganyaya yeCryogenic Valves
Mavharuvhu eCryogenicmavharuvhu akagadzirwa zvakananga anoshandiswa kudzora kuyerera kwemvura inotonhora zvikuru nemagasi, kazhinji patembiricha dziri pasi pe-40°C (-40°F)Mavharuvhu aya akakosha mukushanda kwemaindasitirigasi rechisikigo rakanyungudutswa (LNG), nitrogen yemvura, okisijeni, hydrogen, uye helium, apo mavharuvhu akajairwa aizokundikana nekuda kwekumanikidzwa nekupisa, kuputsika kwezvinhu, kana kutadza kushanda kwechisimbiso.
Kuti ive nechokwadi chekuti mavharuvhu e cryogenic anoshandiswa zvakachengeteka uye zvinobudirira, akagadzirwa nezvinhu zvakasiyana, matanda akatambanudzwa, uye nzira dzakagadzirwa dzekuvharira kuti dzikwanise kumira tembiricha dzakaderera zvikuru pasina kubuda kwemvura kana kutadza kushanda zvakanaka.
2. Zvinhu Zvikuru zveMagadzirirwo eCryogenic Valve
Kusiyana nemavharuvhu echinyakare, mavharuvhu e cryogenic ane zvinhu zvakati wandei zvekugadzira kuti agone kutonhora zvakanyanya:
2.1 Bonnet Yakawedzerwa (Kuwedzerwa kweStem)
- Inodzivirira kutamiswa kwekupisa kubva munzvimbo yakapoteredza kuenda kumuviri wevharuvhu, zvichideredza kuumbwa kwechando.
- Inochengetedza chiputiriso neactuator patembiricha yekunze kuitira kuti ishande zvakanaka.
2.2 Zvinhu Zvinokosha zveKuvhara
- MashandisirwoPTFE (Teflon), graphite, kana zvisimbiso zvesimbikuchengetedza kuvharwa kwakasimba kunyangwe pakupisa kwakanyanya.
- Inodzivirira kubuda kwemvura, izvo zvakakosha pamagasi ane njodzi akadai seLNG kana oxygen yemvura.
2.3 Zvinhu Zvine Muviri Wakasimba
- Yakagadzirwa kubvasimbi isina ngura (SS316, SS304L), simbi dzemhangura, kana nickel alloyskuramba kuputsika.
- Mamwe mavharuvhu e cryogenic ane pressure yakakwira anoshandisasimbi yakagadzirwakuti uwane simba rakawedzerwa.
2.4 Kudzivirira Vacuum (Sarudzo yekusarudza kana paine kutonhora kwakanyanya)
- Mamwe mavharuvhu ane basamajaketi evacuum ane madziro mavirikuderedza kupisa mukati mezvishandiso zvekupisa zvakaderera zvakanyanya.
3. Kupatsanurwa kwemavharuvhu eCryogenic
3.1 Nekuyera kweTembiricha
| Chikamu | Nzvimbo yekupisa | Mashandisirwo |
| Mavharuvhu Ekupisa Kwakaderera | -40°C kusvika -100°C (-40°F kusvika -148°F) | LPG (propane, butane) |
| Mavharuvhu eCryogenic | -100°C kusvika -196°C (-148°F kusvika -320°F) | Nitrogen yemvura, okisijeni, argon |
| Mavharuvhu eUltra-Cryogenic | Pasi pe -196°C (-320°F) | Hydrogen yemvura, helium |
3.2 Nerudzi rweValve
- Mavharuvhu Ebhora eCryogenic- Yakanakira kudzima nekukurumidza; inowanikwa mumagetsi eLNG uye maindasitiri emagasi.
- Mavharuvhu eGedhi reCryogenic- Inoshandiswa pakuvhura/kuvhara zvizere pasina kudzvanywa kwakanyanya.
- Mavharuvhu eCryogenic Globe- Ipai mitemo chaiyo yekuyerera kwemvura mumapaipi emvura anoyerera.
- Mavharuvhu Ekuongorora ECryogenic- Dzivirira kudzoka kwemvura mumasisitimu ane tembiricha yakaderera.
- Mavharuvhu eBhabhatafurayi Ane Cryogenic– Huremu hwakareruka uye hudiki, hwakanakira mapaipi ane dhayamita hombe.
3.3 Nekushandisa
- Mavharuvhu eLNG- Bata gasi rechisikigo rakanyungudutswa pa-162°C (-260°F).
- Ndege neDziviriro- Inoshandiswa mumaroketi emafuta (hydrogen yemvura neokisijeni).
- Zvekurapa & Sainzi- Inowanikwa mumichina yeMRI uye mukuchengetedza cryogenic.
- Kugadzira Gasi reMaindasitiri- Inoshandiswa mumiti inoparadzanisa mhepo (okisijeni, nitrogen, argon).
4. Mabhenefiti eCryogenic Valve
✔Kushanda Kusingabvumiri Kubuda Kwemvura- Kuvhara kwepamberi kunodzivirira kubuda kwegasi rine njodzi.
✔Kushanda Zvakanaka Kwekupisa– Mabhoneti akareba uye zvinodzivirira kupisa zvinoderedza kutamiswa kwekupisa.
✔Kugara kwenguva refu– Zvinhu zvepamusoro-soro zvinoramba kutsemuka uye kuputsika.
✔Kutevedzera Kuchengetedzeka- ZvinosanganaASME, BS, ISO, uye APImitemo yekushandiswa kwe cryogenic.
✔Kugadziriswa Kushoma- Yakagadzirirwa kuvimbika kwenguva refu mumamiriro ezvinhu akaoma.
5. Musiyano Mukuru Pakati peCryogenic neOrdinary Valve
| Chinhu | Mavharuvhu eCryogenic | Mavharuvhu Akajairika |
| Nzvimbo yekupisa | Pazasi-40°C (-40°F) | Pamusoro-20°C (-4°F) |
| Zvinhu | Simbi isina chinhu, nickel alloys, ndarira | Simbi yekabhoni, simbi yakakandwa, purasitiki |
| Rudzi rweChisimbiso | PTFE, graphite, kana zvisimbiso zvesimbi | Rabha, EPDM, kana standard elastomers |
| Dhizaini yeHunde | Bhoneti yakawedzerwakudzivirira icing | Kureba kwehunde kwakajairika |
| Kuedzwa | Kuyedzwa kwekudzivirira kweCryogenic (nitrogen yemvura) | Kuyedzwa kwekumanikidzwa kwemhepo |
Mhedziso
Mavharuvhu eCryogeniczvakakosha kumaindasitiri anobata zvinwiwa zvinopisa zvakanyanya. Dhizaini yavo yakasarudzika—inemabhaneti akareba, zvisimbiso zvinoshanda zvakanyanya, uye zvinhu zvinogara kwenguva refu—zvinoita kuti mashandiro azvo ashande zvakachengeteka uye zvinobudirira mumamiriro ezvinhu akaoma. Kunzwisisa marongerwo azvo, zvakanakira, uye musiyano kubva kumavharuvhu akajairwa kunobatsira pakusarudza vharuvhu yakakodzera yekushandiswa kwakasimba kwe cryogenic.
