wekutanga. Imhandoi yekuvhara{1}vharuvhu yakaiswa handwheel mechanism?
Chekutanga, tinofanira kujekesa mubvunzo wekuti rudzii rwevharuvhu yekuvharisa{0}yakaiswa paruoko. Ruoko rwegumbo remagetsi actuator ndiyo yakajairwa gadziriso, uye hapana mubvunzo wekuti wogadzika vhiri reruoko, saka gakava riripo nderokuti iyo pneumatic valve inoda kuseta ruoko vhiri michina.
chepiri. Ndeipi basa rehandwheel mechanism?
1. Kana chiratidzo chemhepo kana chiratidzo chemagetsi chikakundikana, kana kana zvikamu zvikuru zve actuator (zvakadai se diaphragm, chitubu, chisimbiso, kutumira, nezvimwewo) zvakakanganisika, kushandiswa otomatiki kunofanira kuchinjwa kukushanda kwemaoko, uye handwheel inogona kushandiswa Iyo nzira inoramba ichichengetedza basa rekugadzirisa revhavha inogadzirisa.
2. Iyo handwheel mechanism inogonawo kushandiswa semuganho wekugadzirisa valve stroke. (Limit basa)
3. Chigadzirwa chemaoko chinogona kuvandudza kuvimbika kwekushanda kwevhavha inogadzirisa. Kana iyo bypass yakawedzerwa kune inodzora valve, mari yekudyara yakakura, nzvimbo yacho yakakura, uye mutengo wakakwira kana caliber yakakura kana masimbi anokosha anoshandiswa. Zvinonyanya kudhura-kushandisa vhiri reruoko zvisinei nemutengo wekudyara kana nzvimbo yepasi.
chetatu. Ko vharuvhu yekuvhara{1}inoda kuve nemagetsi emaoko?
Kunyangwe iyo-vharuvhu yekudzima ine mavhiri eruoko, hapana mhinduro yechokwadi, zvakanyanya nekuda kwekufunga nezvemashandisirwo akasiyana-siyana, panofanira kuva nekutengeserana-hukama.
1 Tichitarisa kubva pane zvinodiwa neHG/T20507-2014, inonyanya kukoshesa kupindirana kudzivirira kugadzirwa kwegumbo remaoko kubva pakukanganisa kuurayiwa kwezviito zvinopindirana.
2SH/T3005-2016 haitsanangure kuti inoda kusetwa, asi inoisa mberi zvimwe zvipingaidzo.
3 Kazhinji, vharafu-yakadzimwa ine chekuita nekuchengetedzwa kwevharuvhu haifanirwe kupihwa mavhiri emaoko. Kune mamwe mavharuvhu akavharwa-asingabatanidzwi mukuchengetedzwa kwekuchengetedza, kubva pakuona kwekugadzirwa kwemaitiro, maererano nekukosha kwekutonga kwemaitiro, hapana nzira yekunzvenga uye kutadza kwevharuvhu hakuzokonzeri kuremara kwekugadzira mukati menguva shoma inodzoreka. Muchiitiko ichi, tichifunga kuti panogona kunge kune kukanganiswa kwevashandi panguva yekushanda kwemazuva ose, kuvhara kwevhavhavha, nezvimwewo, unogona kufunga kuwedzera matanho ekutungamirira anoenderana, akadai sekuvhara maoko kana kubvisa handwheel.
