Mavharuvhu egedhi akagadzirirwa basa rakazaruka kana rakavharwa zvakazara. Iwo akaiswa mumapaipi seanoparadzanisa mavharuvhu, uye haafanire kushandiswa sekudzora kana kudzora mavharuvhu. Kushanda kwevharuvhu yegedhi kunoitwa kuita kana wachi yekuvhara (CTC) kana newachi kuvhura (CTO) inotenderera inofamba yedzinde. Paunenge uchishanda tsinde yevharuvhu, gedhi rinofamba richikwira- kana pasi pachikamu chakarukwa chedzinde.

Mavharuvhu egedhi anowanzo shandiswa kana kushomeka kwekumanikidzwa kurasikirwa uye kusununguka kusununguka kunodiwa. Kana yakazaruka zvakakwana, chigadziro chegedhi chegedhi hachina chipingamupinyi munzira yekuyerera chinokonzera kurasikirwa kwakanyanya kwekumanikidzwa, uye iyi dhizaini inoita kuti zvikwanise kushandisa pombi-yekuchenesa nguruve. Chivharo chegedhi ivharuvhu yakawanda zvichireva kuti kushanda kwevharuvhu kunoitwa nedzinde rine shinda. Sezvo vharafu inofanirwa kutendeuka kakawanda kuti iende kubva pakavhurika kuenda kunzvimbo yakavharwa, iyo inononoka mashandiro inodzivirirawo mhedzisiro yesando yemvura.

Mavharuvhu egedhi anogona kushandiswa kunhamba yakawanda yemvura. gedhi mavharuvhu akakodzera pasi peanotevera mamiriro ekushanda:

• Mvura inonwiwa, mvura yetsvina uye zvinwiwa zvisina kwazvakarerekera: tembiricha iri pakati -20 ne +70 °C, yakakwira 5 m/s kuyerera kwevelocity uye inosvika 16 bar differential pressure.
• Gasi: tembiricha iri pakati -20 ne +60 °C, yakakura 20 m/s kuyerera velocity uye inosvika 16 bar differential pressure.

Parallel vs wedge-shaped gedhi mavharuvhu

Mavharuvhu egedhi anogona kukamurwa kuita marudzi maviri makuru: Parallel uye wedge-shaped. Mavharuvhu anoenderana negedhi anoshandisa gedhi rakati sandara pakati pezvigaro zviviri zvakaenderana, uye rudzi rwakakurumbira ivharuvhu yegedhi rakagadzirwa nemuromo wakapinza pazasi pegedhi. Mavharuvhu emagedhi akaita seweji anoshandisa zvigaro zviviri zvakarerekera uye gedhi rakarerekera zvishoma.

Metal agere vs resilient akagara gedhi mavharuvhu

Isati yaunzwa pamusika, mavharuvhu emagedhi ane simbi akagara wedge aishandiswa zvakanyanya. Iyo conical wedge dhizaini uye angular sealing zvishandiso zvesimbi yakagara wedge inoda depression muzasi pevharuvhu kuti ive nechokwadi chekuvharika kwakasimba. Apa, jecha nehurungudo zvakanyudzwa muchibhorani. Iyo pombi system haizombove yakasununguka zvachose kubva kune tsvina zvisinei nekuti iyo pombi inonyungudika sei pakuiswa kana kugadziriswa. Saka chero simbi wedge inozopedzisira yarasikirwa nekukwanisa kwayo kudonhedza-yakasimba.

Ivharuvhu yegedhi yakagadzikana ine vharafu isina kujeka inobvumira nzira yemahara yejecha nematombo muvharuvhu. Kana tsvina ikapfuura sezvo vharuvhu inovhara, rubber surface inovhara zvakapoteredza tsvina apo valve yakavharwa. Mushonga werubha wemhando yepamusoro unobata tsvina sezvo vharuvhu inovhara, uye tsvina ichabviswa kana vharuvhu yavhurwa zvakare. Iyo rubber surface ichawanazve chimiro chayo chepakutanga ichichengetedza kudonha-tight chisimbiso.

Mavharuvhu mazhinji emagedhi akatsiga agere, zvisinei mavharuvhu emagedhi esimbi achiri kukumbirwa mune mamwe misika, saka achiri chikamu cherudzi rwedu rwekupa mvura uye kuchenesa mvura.
