Ndeipi Nguva Yekuvhura Nekugumisa Globe Valve

Nguva yekutanga neyokugumisa yevharuvhu yepasi roseinguva inotora kuti dhisiki revharuvhu rifambe kubva pakuvharwa zvizere kusvika pakuvhurwa zvizere, kana kubva pakuvhurwa zvizere kusvika pakuvhurwa zvizere. Nekuti vharuvhu yepasi rose inoshandisa tsinde rinokwira rakatsetseka uye vhiri reruoko rinotenderera kakawanda kana actuator, nguva yaro yekushanda inowanzo kureba kupfuura mavharuvhu akadai semavharuvhu ebhora kana mavharuvhu ebhururu.

Nguva Yakajairika Yekuvhura Nekuvharwa

①Vharuvhu yeGlobe yeManual

• Saizi diki (DN15–DN50):
  Masekondi mashanu kusvika gumi nemavirinekutenderera kwevhiri reruoko kwakajairika.

• Saizi dziri pakati nepakati (DN65–DN150):
  Masekondi gumi kusvika makumi maviri nemashanuzvichienderana nekufamba kwemidzi uye simba remushandisi.

• Saizi hombe (DN200–DN350 zvichikwira):
  Masekondi 25–60 kana kupfuura, sezvo vachida kutendeuka kakawanda kuti vafambise dhisiki.

②Vharuvhu yeGlobe yemagetsi inofambiswa

• Mazhinji ma actuator emagetsi anoshanda mukati me:
  Masekondi makumi maviri kusvika makumi matanhatu (kumhanya kwakajairika)
  Mavharuvhu makuru anononoka anogona kutora masekondi zana nemakumi maviri kuti adzivirire mvura inoyerera.

③Vharuvhu yeGlobe yePneumatic Actuated

• Inokurumidza kupfuura yemagetsi asi inononoka kupfuura mavharuvhu anovhura/adzima.
  Nguva yekushandiswa: masekondi 3–20, zvichienderana nemhepo inowanikwa uye saizi yeactuator.

Nei Mavharuvhu Epasi Achitora Nguva Yakareba Kushanda

• ①Hunde inofanira kufamba daro refu kuti ikwanise kuyerera nemazvo.

• ②Vhiri reruoko rinoda kutenderera kakawanda kudzivirira kuchinja kwekumanikidzwa kamwe kamwe.

• ③Dhizaini yevharuvhu inokoshesa kudzora kuyerera kwemvura uye kururama kwayo pachinzvimbo chekudzima nekukurumidza.

• ④Kushanda zvishoma nezvishoma kunobatsira kuderedza mvura inoyerera, kunyanya mumabasa emugungwa nemaindasitiri.

Zvinhu Zvinokanganisa Nguva Yekushanda

• ①Saizi yevharuvhu uye chiyero chekumanikidzwa

• ②Kukwira kweshinda (shinda dzakatetepa = kufamba zvishoma nezvishoma)

• ③Rudzi rwemuchina wekufambisa magetsi (wekushandisa nemaoko, wemagetsi, wepneumatic, wehydraulic)

• ④Kumanikidzwa kwesystem

• ⑤Kukweshana kana kupera mukati mevharuvhu

• ⑥Magadzirirwo etorque kana kumhanya pama actuators

Pakushandiswa kwemvura, kuvhara zvishoma nezvishoma kunoshandiswa nemaune kudzivirira masisitimu emvura yegungwa, mitsetse yekusimbisa, uye masisitimu ekutonhodza kubva pakumanikidzwa kamwe kamwe.
