Zvisinei, kukwenya pamigero yakaderera kwazvo (pasi pe15–20%) kana pakati pemadhigirii akakwirira kunogona kutungamira ku cavitation mu liquid service. Mavharuvhu matatu anopa throttling performance yepamusoro nekuda kwe high control ratio yawo. Kuti uwane chaiyo throttling control, tarisa ma flow coefficient (Cv) curves emugadziri uye data re cavitation rehukuru hwevharuvhu chaiyo uye trim.
Maitiro ewafer:Vharuvhu iyi yakasungirirwa pakati pemaflange maviri emapaipi. Iyi ndiyo gadziriro inodhura zvakanyanya asi haibvumidze kubviswa kwepombi dzinodzika pasi pasina kuderedza kudzvanywa kwesystem. Mavharuvhu eWafer akachipa ne20–40% pane mavharuvhu eLug ane saizi imwe chete.
Maitiro emakumbo:Muviri wevharuvhu une tambo dzakaiswa (lugs) kumativi ese, zvichibvumira mabhaudhi kuflanges kumativi ese ari ega. Izvi zvinoita kuti pave nebasa re dead-end, zvichireva kuti mapaipi epasi anogona kubviswa ukuwo divi rekumusoro richiramba rakamanikidzwa—zvinokosha pakugadzirisa. Mavharuvhu emakumbo anopawo simba rekuwedzera remakanika mumasisitimu ari pasi pekumanikidzwa kwepaipi.
Maitiro ese ari maviri anowanikwa muzvikamu zviviri zvekuvhara.
Sarudza katatu kana:
- Tembiricha dzinopfuura 260°C (muganho unoshanda wezvigaro zvePTFE/RPTFE)
- Kushandiswa kunoda kudzima simbi kubva kusimbi kusvika kusimbi zvachose pasina kubuda kwemvura
- Basa rinosanganisira kupatsanurwa kwemhepo inopisa kana kuti hydrocarbon uko kuchengetedzeka kwemoto kuri pamutemo
- Kuverenga kwese kwese kunoda kuramba kwakanyanya kupfeka
- Vharuvhu iyi inoshandiswa mukuita cryogenic service (LNG, ethylene)—mavharuvhu matatu ane zvinhu zvakakodzera anoshanda zvakanaka pakupisa kwakaderera zvakanyanya.
Sarudza double offset (standard high-performance) kana:
- Tembiricha dziri pasi pe260°C
- Zvigaro zvePTFE kana zvakasimbiswa zvePTFE zvinopa makemikari akakodzera
- Hupenyu hwekufamba kwemuviri hune mwero (makumi ezviuru zvekufamba kwemuviri) hunosangana nezvinodiwa
- Mutengo wekutanga wepasi wemari ndiyo inonyanya kukosha
Kuedzwa kwakazvimirira kwakaratidza kuvharwa kwemagetsi kusina kuvharwa nemabubble-tight kuburikidza nema cycles anopfuura 100,000 emhando yepamusoro ema double offset butterfly valves. Ma triple offset valves, ane zvigaro zvesimbi uye geometry isina kukweshana, anogona kuwana hupenyu hwakareba hwekushanda—kazhinji hunopfuura 250,000 cycles mumamiriro ekushanda ari pakati nepakati. Hupenyu hwekufamba kwemagetsi chaihwo hunoenderana nemamiriro ekushanda, kusanganisira kumanikidzwa, tembiricha, kuchena kwemvura, uye kumhanya kwekushanda.
Kwete. Chinhu chikuru chekugadzira kwepamusoro-soro kugona kuvhara mavharuvhu maviri. Kusiyana nemavharuvhu mazhinji emabhatafurayi akabatana, ayo anogona kunge aine nzira yekuyerera yakanamirwa pamuviri, mavharuvhu anoshanda zvakanyanya anochengetedza kushanda kwakazara kwekuvhara pasinei nekwakaiswa. Izvi zvinoita kuti kuiswa kuve nyore uye zvinoderedza njodzi yekuiswa zvisiri izvo.
