Butterfly volve ruzivo rwekukurukurirana

Mune makumi matatu,Butterfly ValveYakagadzirwa muUnited States, yakaunzwa kuJapan mumakumi mashanu, uye yakashandiswa zvakanyanya muJapan mumakore makumi matanhatu, uye yakakwidziridzwa muChina mushure memakore makumi manomwe. Parizvino, butterbly mavhavha pamusoro peDN300 mm munyika yakaputuka zvishoma nezvishoma gate mavharuvhu. Zvichienzaniswa neGedhi Valves, butterfly mavhavha vane pfupi pfupi kuvhura uye nguva yekuvhara, diki yekushandisa torque, diki yekuisa nzvimbo uye uremu hwechiedza. Kutora DN1000 semuenzaniso, iyo butterfly vharuvhu iri pamusoro pe2t

Iko kukanganisa kweiyo rubber chisimbisoButterfly ValveNdozvazviri kana ichishandiswa pakutya, cavation ichaitika nekuda kwekushandiswa zvisina kunaka, iyo ichaita kuti chigaro cherab shakisa chichibva chobva chakuvadzwa. Mumakore achangopfuura, China zvakare vakagadzirawo mavhekita akasungwa ebutoro butters, uye mumakore achangopfuura, Japan yakagadzirawo mavharubwe akavezwa muButter neyekupesana, nekudzikira kwenguva refu uye ruzha.

Hupenyu hwebasa hwechigaro chemukuru chisinga chisimbiso ndeye makore 15-20 nekuda kwerabha uye 80-90 makore esimbi pasi pemamiriro ezvinhu akajairwa. Nekudaro, maitiro ekusarudza nenzira kwayo zvinoenderana nezvinodiwa zvekushanda mamiriro.

Hukama pakati pekuvhurwa kweButterfly Valveuye iyo yekuyerera iyo inoyerera ndeyechokwadi mutsara uye chikamu. Kana ikashandiswa kudzora huwandu hwekuyerera, hunhu hwayo hune hukama nekuenderera mberi kwekuparadza pombi, uye kurasika kwepombi kwakafanana kwakasiyana, uye kuyerera kweValve kuchave kwakasiyana kwazvo.

Kana vharuvhu iri mumamiriro ekurova kukuru, kumashure kweparavha ndiro inowanzoita kuti ishandise kuvharidzira vharuvhu, saka inowanzo shandiswa kunze kwe15 °.

Kana butterfly vharuvhu iri pakati pekuvhura kwepakati, iyo yekuvhura chimiro yakaumbwa nevalveMuviri uye Kupera Kwemberi kweButterfly Plate kwakanangana neValve Shaft, uye kuguma kwemvura inoyerera, uye rumwe rutivi rwakafanana nekuvhurwa kwegwenzi. pane kudivi revaRido, uye kudzvanywa kwakaipa kuchagadzirwa pasi pevhudzi reruoko renhare, uye chisimbiso cheRabha chinowanzowira pasi.

Torque yekushandisa butterlfly volve, nekuda kwekuvhura kwakasiyana uye kwekuvhura kwekuvharirwa kwevharuvhu, kunyanya vharuvhu rakadzika, neTourque yakagadzirwa nemusoro wepamusoro uye yakaderera musoro wevheni haigone kufuratirwa. Mukuwedzera, apo iyo yeruboshwe yakaiswa pane iyo inlet rutivi rwevharuvhu, kuyerera kunoyerera kunoumbwa, uye torque inowedzera. Kana iyo vharuvhu iri pakati pekuvhura kwepakati, iyo mechanism yekushandisa inoda kuzvivhara nekuda kwekuita kweiyo mvura yeTorque.
