Theepurasitiki butterfly valveyakabatanidzwa kune pipeline system nenzira dzinotevera:

Butt welding connection: Iyo dhayamita yekunze yevhavha yekubatanidza chikamu yakaenzana nedhayamita yekunze yepombi, uye kuguma kwechiso chechikamu chekubatanidza chevhavha chinopesana nekuguma kwepombi yewelding;

Socket bonding connection: chikamu chekubatanidza chevhavha chiri muchimiro chechigadziko, chinosungirirwa kune pombi;

Electrofusion socket connection: chikamu chevharuvhu yekubatanidza imhando yesoketi ine tambo yemagetsi yekudziya yakaiswa padhayamita yemukati, uye ndeye electrofusion kubatana nepombi;

Socket hot-melt connection: chikamu chekubatanidza valve chiri muchimiro chechigadziko, uye chakabatanidzwa nepombi ne-hot-melt socket;

Socket bonding connection: Chikamu chekubatanidza chevhavha chiri muchimiro chechigadziko, icho chinosungirirwa uye chinogadziriswa nepombi;

Socket rubber sealing ring connection: Chikamu chekubatanidza chevhavha imhando ye socket ine rubber sealing ring mukati, iyo yakasungirirwa uye yakabatanidzwa nepombi;

Kubatana kweFlange: Chikamu chekubatanidza chevhavha chiri muchimiro cheflange, iyo yakabatana neflange papombi;

Thread connection: Chikamu chekubatanidza valve chiri muchimiro cheshinda, iyo yakabatanidzwa neshinda papombi kana pombi yekuisa;

Live connection: Iyo valve yekubatanidza chikamu ndeye mhenyu yekubatanidza, iyo yakabatana nayomapaipi kana fittings.

Ivhavha inogona kuva nemhando dzakasiyana dzekubatanidza panguva imwe chete.

Hukama huri pakati pekuvhurwa kwevharuvhu yepurupiti yepurasitiki uye chiyero chekuyerera chinoshanduka mutsara.Kana iyo yakashandiswa kudzora kuyerera, maitiro ayo ekuyerera anowiriranawo zvakanyanya nekuyerera kwekupokana kwepombi.Semuenzaniso, mapaipi maviri akaiswa neakaenzana dhayamita yevharuvhu uye fomu, asi pombi kurasikirwa coefficient yakasiyana, uye kuyerera kwevhavha kuchave kwakasiyana kwazvo.

Kana iyo valve iri muhurumende ine throttle yakakura, kumashure kweplate yevhavha inotarisana ne cavitation, iyo inogona kukuvadza valve.Kazhinji, inoshandiswa kunze kwe15 °.

Kana vharafu yepurasitiki yevharuvhu iri pakati pekuvhura, chimiro chekuvhura chinoumbwa nemuviri wevharuvhu uye kumucheto kwemberi kweshavishavi ndiro inonangana nevharuvhu shaft, uye mativi maviri anoumbwa kuti apedze nyika dzakasiyana.Kunoperera ndiro yeshavishavi kune rimwe divi kunofamba ichienda kwainoyerera mvura, uye rimwe divi richipesana nekwairi kuyerera.Naizvozvo, rimwe divi remuviri wevharuvhu neplate yevharuvhu inoumba kuvhurika-kunge kuvhurika, uye rumwe rutivi rwakafanana nekuvhurika kwemhepo.Rutivi rwenozzle rune kukurumidza kuyerera kweyero kupfuura iyo throttle side, uye kudzvanya kwakashata kunogadzirwa pasi peiyo throttle side valve.Zvisimbiso zverabha zvinowanzodonha.

Mavharuvhu epurasitiki nemashavishavi haakwanisi kuzvivharira.Pakuisa ndiro yeshavishavi, chinoderedza giya rehonye chinofanira kuiswa parutanda rwevharuvhu.Kushandiswa kwegonye gear reducer haigoni kuita chete butterfly plate self-locking uye kumisa ndiro ye butterfly pane chero nzvimbo, asiwo inovandudza kushanda kwevhavha.

Iyo torque yekushandisa yepurasitiki butterfly valve ine hunhu hwakasiyana nekuda kwekusiyana kwekuvhura uye kuvhara nzira dzevhavha.Iyo yakadzikama butterfly valve, kunyanya iyo yakakura-diameter valve, nekuda kwekudzika kwemvura, torque inogadzirwa nemusiyano pakati pepamusoro uye yakadzika misoro yemvura yevhavha shaft haigone kuregererwa.Uye zvakare, kana gokora rakaiswa padivi rekupinza revhavha, kuyerera kwe bias kunoumbwa, uye torque inowedzera.Kana vharuvhu iri pakati pekuvhura, iyo inoshanda sisitimu inoda kuzvivharira yega nekuda kwekuita kwemvura inoyerera torque.

Ipurasitiki butterfly valve ine chimiro chiri nyore, chinosanganisira zvikamu zvishomanana, uye inochengetedza kushandiswa kwezvinhu;saizi diki, uremu huremu, saizi diki yekuisa, diki yekutyaira torque, nyore uye nekukurumidza kushanda, inongoda kutenderera 90 ° kukurumidza kuvhura nekuvhara;uye Panguva imwecheteyo, ine zvakanaka kuyerera kwekugadzirisa basa uye kuvhara uye kuisa chisimbiso maitiro.Mundima yekushandiswa yehukuru uye hwepakati caliber, yepakati uye yakaderera kumanikidza, shavishavivharuvhu ndiyo inotonga vharafu fomu.Kana shavishavi vharafu iri munzvimbo yakanyatsozaruka, ukobvu hweshavishavi ndiro ndiyo chete inopikisa apo svikiro rinoyerera nemuviri wevharuvhu, saka kudonha kwemhepo kunogadzirwa nevharuvhu kudiki, saka ine zviri nani kuyerera kwekudzora maitiro.Iyo butterfly valve ine mhando mbiri dzekuisa chisimbiso: elastic seal uye simbi chisimbiso.Elastic sealing valve, mhete yekuisa chisimbiso inogona kuvharirwa pamuviri wevharuvhu kana kusungirirwa kunharaunda yefurafura yeshavishavi.Mavharuvhu ane zvisimbiso zvesimbi kazhinji ane hupenyu hwakareba kupfuura mavharuvhu ane elastic seal, asi zvakaoma kuwana chisimbiso chakakwana.Iyo simbi chisimbiso inogona kuenderana nepamusoro tembiricha yekushanda, nepo elastic chisimbiso chine hurema hwekudzikiswa netembiricha.Kana iyo butterfly valve ichidikanwa kuti ishandiswe sekudzora kuyerera, chinhu chikuru ndechekusarudza saizi uye rudzi rwevhavha.Nheyo yemaitiro evhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha ndiyo inonyanya kukodzera kugadzira mavharuvhu makuru.Butterfly mavharuvhu haango shandiswa zvakanyanya mumaindasitiri akajairwa akadai se petroleum, gasi, makemikari, uye kurapwa kwemvura, asi zvakare anoshandiswa mukutonhodza mvura masisitimu ezviteshi zvemagetsi zvinopisa.The rinowanzoshandiswa shavishavi mavharuvhu zvinosanganisira chimedu rudzi shavishavi mavharuvhu uye flange mhando shavishavi mavharuvhu.Wafer butterfly mavharuvhu akabatana pakati pepombi mbiri dzine mabhaudhi.Flanged butterfly mavharuvhu ane maflange pavharuvhu.Mafuraji pamagumo ose evhavha akabatanidzwa kune pombi flanges ane mabhoti.Kushanda kwesimba kwevharuvhu kunoreva kugona kwevharuvhu kutsungirira kudzvanywa kwepakati.Ivhavha iyi chigadzirwa chemagetsi chinotakura kumanikidzwa kwemukati, saka inofanira kuva nesimba rakakwana uye rigidity kuti ive nechokwadi chekushandiswa kwenguva refu pasina kuputika kana deformation.

Nekushandiswa kweanti-corrosion synthetic rubber uye polytetrafluoroethylene, kushanda kwemavharuvhu e butterfly kunogona kuvandudzwa uye kusangana nemamiriro ekushanda akasiyana.Mumakore gumi apfuura, mavharuvhu esimbi anovhara shavishavi akagadzirwa nokukurumidza.Nekushandiswa kwekudzivirira kwekushisa kwepamusoro, kushorwa kwekushisa kwakadzika, kupikisa kwakasimba kwekuora, kupikisa kwakasimba kwekukukurwa, uye simba rakawanda remagetsi emagetsi mumavharuvhu eshavishavi, mavharuvhu esimbi anosunga butterfly akashandiswa mukupisa kwakanyanya, kupisa kwakaderera, uye kukukurwa kwakasimba.Yakave ichishandiswa zvakanyanya pasi pemamwe mamiriro ekushanda uye chikamu chakatsiva vharuvhu yepasi,vharafu yegedhiuye vharafu yebhora.
