Semuenzaniso, kana iwe uchida kuvhura DN100, PN10 butterfly valve, torque value ndeye 35NM, uye urefu hwemubato ndeye 20cm (0.2m), ipapo simba rinodiwa i170N, iyo yakaenzana ne17kg.
The butterfly valve ivharuvhu inogona kuvhurwa nekuvharwa nekushandura vharafu ndiro 1/4 kutendeuka, uye nhamba yekutendeuka mubato zvakare 1/4 kutendeuka.Ipapo nguva inodiwa kuvhura kana kuvhara inotarwa ne torque.Iyo yakakura torque, iyo inononoka vharafu inovhura nekuvhara.neimwe nzira.
2. Worm gear actuated butterfly valve:
ane mavharuvhu eshavishavi ane DN≥50.Pfungwa inokanganisa huwandu hwekutendeuka nekumhanya kweworm gear butterfly valve inonzi "speed ratio".
Chiyero chesipidhi (speed ratio) zvinoreva chiyero chiri pakati pekutenderera kweactuator output shaft (handwheel) nekutenderera kweplate yevharuvhu reshavishavi.Semuenzaniso, spidhi reshiyo yeDN100 turbine butterfly valve i24: 1, zvinoreva kuti handwheel pabhokisi returbine inotenderera ka24 uye butterfly plate inotenderera denderedzwa 1 (360 °).Nekudaro, iyo yakanyanya kuvhura angle ye butterfly plate ndeye 90 °, inova 1/4 denderedzwa.Saka, handwheel pabhokisi returbine inoda kushandurwa ka6.Nemamwe manzwi, 24:1 zvinoreva kuti unongoda kutenderedza vhiri reruoko returbine butterfly valve 6 kutendeuka kuti upedze kuvhura kana kuvhara kwevharuvhu.

1. Bata shavishavi rinoshandiswa:
Kazhinji akashongedzerwa pa butterfly mavharuvhu ane DN ≤ 200 (yakanyanya saizi inogona kuva DN 300).Panguva ino, tinofanira kutaura pfungwa inonzi "torque".
Torque zvinoreva huwandu hwesimba rinodiwa pakuvhura kana kuvhara vharuvhu.Iyi torque inobatwa nezvinhu zvakasiyana-siyana, zvinosanganisira ukuru hwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha,kunzvinyiwa uye zvimiro zvemidhiya, uye kukandirana mukati megungano revharuvhu.Torque tsika dzinowanzo kuratidzwa muNewton metres (Nm).

3. Electric actuated butterfly valve:
Yakagadzirwa neDN50-DN3000.Rudzi rwakakodzera mavharuvhu eshavishavi ndiyo kota-turn electric device (inotenderera angle 360 degrees).Iyo yakakosha parameter ndeye torque, uye iyo unit ndeyeNm
Nguva yekuvhara yemagetsi butterfly valve inogadziriswa, zvichienderana nesimba, mutoro, kukurumidza, nezvimwe zve actuator, uye kazhinji haisi kupfuura 30 seconds.
Saka zvinotora majana mangani kuvhara vharuvhu yeshavishavi?Nguva yekuvhura nekuvhara yevhavhavhavha inotsamira pakumhanya kwemota.Iko kubuda kumhanya kweZFA valvekumidziyo yemagetsi yakajairika ndeye 12/18/24/30/36/42/48/60 (R/min).
Semuenzaniso, kana musoro wemagetsi une kumhanya kwekutenderera kwe18, uye nguva yekuvhara yemasekondi makumi maviri, ipapo nhamba yekutendeuka inovhara ndeye 6.
