Mavharuvhu egedhi

Mavharuvhu egedhi anonyanya kugadzirirwa kutanga kana kumisa kuyerera, uye kana yakatwasuka-mutsara kuyerera kwemvura uye kushoma kuyerera kurambidzwa kunodiwa. Mukushandira, mavharuvhu aya anowanzo kuvhurika zvakazara kana kuvharwa zvakazara.

Iyo diski yevhavha yeGedhi inobviswa zvachose kana vharuvhu yakazaruka; dhisiki rakakweverwa zvizere kumusoro muvharuvhu Bonnet. Izvi zvinosiya mukana wekuyerera nemuvharuvhu pane imwechete yemukati dhayamita sepombi inoiswa vharuvhu. Ivhavha yeGedhi inogona kushandiswa kune zvakasiyana-siyana zvezvinwiwa uye inopa chisimbiso chakasimba kana yakavharwa.

Kuvakwa kwevhavha yeGedhi

Mavharuvhu egedhi ane zvikamu zvitatu zvikuru: muviri, bonnet, uye trim. Muviri unowanzo kubatanidzwa kune zvimwe midziyo kuburikidza neflanged, screwed kana welded. Iyo bhoneti, iyo ine zvikamu zvinofamba, inosungirirwa kumuviri, kazhinji nemabhaudhi, kubvumidza kuchengetedza. Ivhavhavha yekucheka ine hunde, gedhi, disc kana wedge nemarin'i echigaro.

Madhisiki evhavha yeGedhi

Mavharuvhu egedhi anowanikwa nemadhisiki akasiyana kana wedges. Kuchinja kweGedhi mavharuvhu kunowanzo gadzirwa nemhando yeweji inoshandiswa.

Dzainyanyozivikanwa dzaiva:

• Solid wedge ndiyo inonyanya kushandiswa dhisiki nekureruka kwayo uye kusimba kwayo.
  Ivhavha ine rudzi urwu rweweji inogona kuiswa panzvimbo imwe neimwe uye inokodzera zvinenge zvese zvinwiwa. Iyo yakasimba wedge ndeye-imwe-chidimbu chakasimba chivakwa, uye chiri kuita mhirizhonga inoyerera.
• Flexible wedge idhisiki rimwechete rine chidimbu chakatenderedza perimeter kuvandudza kugona kugadzirisa kukanganisa kana shanduko mukona pakati pezvigaro.
  Iko kuderedzwa kuchasiyana muhukuru, chimiro uye kudzika. Kucheka kwakadzika, kwakatetepa kunopa kusandunuka kushoma asi kunochengetedza simba.
  Iyo yakadzika uye yakafara kucheka, kana kukanda-mukati recess, inosiya zvishoma zvinhu pakati, izvo zvinobvumira kuwedzera kuchinjika, asi zvinokanganisa simba.
• Split wedge inozvigadzirisa uye inozvinangisa kune ese zvigaro mativi. Iyi wedge mhando ine maviri-zvidimbu kuvaka iyo inogara pakati pezvigaro zvakatepwa mumutumbi wevharuvhu. Rudzi urwu rweweji rwakakodzera kurapwa kwemagasi asingadzore uye zvinwiwa patembiricha yakajairika, kunyanya zvinwiwa zvinoparadza.

Dzinde reGadhivhavha

Iyo tsinde, iyo inobatanidza handwheel uye dhisiki pamwe chete, ine mutoro wekumisikidza kwakakodzera kwedhisiki. Matanda anowanzo kuumbwa, uye akabatanidzwa kune disk ne threaded kana mamwe maitiro. Kuti udzivise kuputika, munzvimbo yechisimbiso, kupera kwakanaka kwepamusoro kwe stem kunodiwa.

Gedhi mavharuvhu akaiswa sezvizvi:

• Rising Stem
• Non Rising Stem

Pavharuvhu yerudzi rweRising Stem, dzinde rinokwira pamusoro pevhiri reruoko kana vharuvhu yakavhurwa. Izvi zvinoitika, nekuti dzinde rakarukwa uye rinobatanidzwa neshinda dzemugwenzi dzeJoko. Joko chikamu chakakosha kubva kuRising Stem valve uye inoiswa paBonnet.

Pavharuvhu yerudzi rweNon Rising Stem, hapana kufamba kwedzinde kumusoro kana vharafu yakavhurwa. Iyo hunde inosungirirwa mudhisiki. Sezvo vhiri reruoko padzinde richitenderedzwa, dhisiki rinofamba richikwira kana kudzika pasi padzinde pashinda uku dzinde richiramba rakamira rakamira.

MuMenu huru "Mavharuvhu" iwe unowana zvinongedzo kune yakadzama (yakakura) dhizaini yeese maviri stem marudzi.

Zvigaro zvevhavha yeGedhi

Zvigaro zveGedhi mavharuvhu zvinopihwa zvakabatanidzwa nemuviri wevharuvhu kana mune yechigaro mhete mhando yekuvaka. Kuvakwa kwemhete yezvigaro kunopa zvigaro izvo zvingave zvakasungirirwa panzvimbo kana kuti zvakatsikirirwa panzvimbo uye chisimbiso chakasungirirwa kumutumbi wevharuvhu. Iyo yekupedzisira fomu yekuvaka inokurudzirwa kune yakakwira tembiricha sevhisi.

Integral zvigaro zvinopa chigaro chezvinhu zvakafanana zvekuvaka semuviri wevharuvhu ukuwo kudzvanywa-mukati kana shinda-mukati zvigaro zvichibvumidza kusiyanisa. Mhete dzakaomarara dzinogona kupihwa kune iyo application painodiwa.

Zvakanakira uye Zvakaipa zveGadhi mavharuvhu

Zvakanakira:

• Good shutoff features
• Mavharuvhu egedhi ane bidirectional uye saka anogona kushandiswa mumativi maviri
• Kurasikirwa kwekumanikidzwa kuburikidza nevhavha ishoma

Zvakaipa:

• Havagoni kukurumidza kuvhurwa kana kuvharwa
• Gedhi mavharuvhu haana kukodzera kudzora kana throttle kuyerera
• Ivo vanonzwa nekudedera munzvimbo yakazaruka
