Valve kuyerera maitiro curve uye classification valve kuyerera maitiro, iri muvharuvhu kumagumo ese ekumanikidza musiyano inoramba iripo mamiriro, iyo yepakati inoyerera kuburikidza nevhavha hama yekuyerera uye kuvhura kwayo pakati pehukama pakati pekuyerera maitiro evharuvhu chinhu chakakosha tekinoroji. zviratidzo uye parameters mugadziriro yekushanda kwevharuvhu kuita sarudzo yakarurama ine zvakakosha zvikuru.

Chimiro chevharuvhu chinoyerera chinogona kutsanangurwa se: kuyerera kwehukama hwepakati inodzorwa kuburikidza nevharuvhu, uye hukama pakati pekuvhurwa kwehama (chikafu chinosimuka) chevharuvhu nevharuvhu kunonzi kuyerera hunhu hwevhavha inotonga. Kazhinji kutaura, yakakamurwa kuita mhando ina: mutsara wakatwasuka, wakaenzana muzana (logarithm), parabola uye nekukurumidza kuvhurika! Tsanangudzo chaiyo uye zvakanakira ndezvizvi:

Kutanga, chimiro chemutsara chinoreva hukama hwemutsara pakati pehuwandu hwekuyerera kwevharuvhu uye kuvhurwa kwehama, ndiko kuti, kuenderera kwekuchinja kwekuyerera kunokonzerwa nekushandurwa kwekuvhurwa kweyuniti. Kufamba kwakabatana kwemaitiro emutsara kuri muhukama hwakatwasuka nechiyero chekuyerera. Kuchinja kwehuwandu hwekuyerera kunokonzerwa nekushandurwa kwechikwata chechikwata chinogara chiripo. Kana chiyero chekuyerera chiri chikuru, kukosha kwehuwandu hwehuwandu hwehuwandu hunochinja hudiki, uye huwandu hwekuyerera hushoma, kukosha kwehuwandu hwehuwandu hunochinja zvikuru.

Chechipiri, iyo yakaenzana muzana hunhu (logarithm) inoreva kuti kuyerera kwehukama kunokonzerwa nekushandurwa kwekuvhurwa kweyuniti kunoenzana nechiyero chekuyerera kweiyo poindi, ndiko kuti, iyo amplification coefficient yevhavha yekudzora iri kuchinja, uye inowedzera kuwedzera kwekuyerera kwehukama. The hama sitiroko uye hukama kuyerera kweakaenzana muzana maitiro haasi muhukama hwemutsara, uye shanduko yekuyerera inokonzerwa nekushandurwa kweyuniti sitiroko pane imwe neimwe nzvimbo yesitiroko inoenderana nekuyerera kweyero panguva ino, uye muzana yekuyerera. shanduko yakaenzana. Nokudaro, ruzivo rwayo nderokuti kuyerera kuduku, kushanduka kushanduka kuduku, uye kana kuyerera kwakakura, kuyerera kunoshanduka zvikuru, ndiko kuti, ine kururamisa kwakafanana mukuzarura kwakasiyana.

Chetatu, hunhu hweparabolic (parabolic character) hunoreva kushanduka kwechikafu chinoitwa neshanduko yekuvhurika kwechikamu muchikamu chakananga kumudzi wepakati wekuyerera ukoshi hwepano. Muyero wekuyerera unosiyana zvichienderana nemativi maviri esitiroko, ane humiro hwepakati hwemutsara uye yakaenzana muzana maitiro.

Chechina, kukurumidza kuvhura kuyerera hunhu kunoreva kuyerera kwakakura kana kuvhurwa kuri kudiki, nekuwedzera kwekuvhura, chiyero chekuyerera chinogona kukurumidza kusvika pakakwirira, uyezve kuwedzera kuvhura, kuyerera kushanduka kudiki kwazvo, saka ndizvo. inonzi fast opening character.

Kuyerera kwemaitiro e diaphragm mavharuvhu ari padyo neanokurumidza kuvhura maitiro, kuyerera hunhu hweshavishavi mavharuvhu ari padyo neakaenzana muzana hunhu, kuyerera hunhu hwemavharuvhu egedhi hunhu hwakatsetseka, kuyerera kwemavharuvhu ebhora mitsara yakatwasuka mukati mekuvhura. uye nhanho yekuvhara, uye yakaenzana muzana maitiro mukuvhurwa kwepakati.

Kazhinji, bhora mavharuvhu uyebutterfly valveskazhinji haashandiswe kugadzirisa, kana akashandiswa kugadzirisa, asi zvakare mune yekuvhurwa kudiki kuita basa mukutonga, kazhinji inogona kuverengerwa semhando yekuvhura nekukurumidza, uye chaiyo semutemo weakawanda epasirese. vharafu, iyo yevhavha yemusoro inogadziriswa kuita senge parabolic cone, spherical, nezvimwewo, ichashandisa akasiyana curve maitiro, anowanzo shandiswa sekugadzirisa, kunyanya chikamu chehunhu chinoshandiswa zvakanyanya.

Tianjin Tanggu Mvura-Chisimbiso Valve Co., Ltdvari kutsigira zvikuru-yepamusoro michina resilient akagara mavharuvhu, kusanganisira resilient akagarawafer butterfly valve,Lug butterfly valve,Double flange concentric butterfly valve, Double flange eccentric butterfly valve,Y-strainer, bancing valve,Wafer dual plate check valve, nezvimwewo.
