Chii chinangwa chevhavha yekuongorora chitubu?
Unoda cheki vharuvhu asi hauzive kuti ndeupi rudzi rwekushandisa. A standard swing kana bhora cheki vharafu inogona kusashanda kana iwe uchida kuiisa yakamira kana pakona.
Chinangwa chechitubu chekuongorora valve ndechekupa chisimbiso chinokurumidza, chakavimbika mune chero kutaridzika. Chitubu chinomanikidza dhisiki kuvharwa pasina kuvimba negiravhiti, kuve nechokwadi kuti inoshanda yakamira, yakatwasuka, kana pakona, uye inodzivirira sando yemvura nekuvhara nekukurumidza.
Chinhu chakakosha pano chitubu. Mune mamwe mavharuvhu echeki, secheki yekugezera, bhachi rakapfava rinovhurika nekuyerera uye rinovhara negiravhiti kana kuyerera kuchidzokera kumashure. Izvi zvinoshanda zvakanaka mumapombi akachinjika, asi haavimbike kana akaiswa vertically. Chitubu chinoshandura mutambo zvachose. Inopazvakanaka-kubatsira kuvhara. Izvi zvinoreva nguva iyo kuyerera kwemberi kunomira, chitubu chinosundidzira disc ichidzokera pachigaro chayo, ichigadzira chisimbiso chakasimba. Ichi chiito chinokurumidza uye chakanyanya kujeka pane kumirira simba rinokwevera zvinhu pasi kana kuti backpressure kuita basa. Kumhanya uku kunobatsirawo kuderedza "sando yemvura,” kuvhundutsa kunokuvadza kunogona kuitika kana kuyerera kwamira kamwe kamwe.” KuBudi, ichikurudzira achitubu cheki vharafukune vatengi vake anovapa kuwedzera kugadzika kuchinjika uye kuchengetedzwa kuri nani.

Ko PVC cheki vharafu inogona kuipa here?
Wakaisa cheki valve makore apfuura uye fungidzira kuti ichiri kushanda nemazvo. Ichi chikamu chekusaona, chekunze-chepfungwa chinogona kunge chiri kutadza chinyararire kwakamirira kuitika, kufuratira chinangwa chayo chose.
Hongu, PVC cheki vharafu inogona zvachose kuipa. Izvo zvinonyanya kutadza kuita marara anoisa vharafu yakavhurika, chitubu chemukati chiri kupera simba kana kutyoka, kana chisimbiso cherabha chichisakara nekutadza kugadzira chisimbiso chakasimba. Ichi ndicho chikonzero kuongorora nguva nenguva kwakakosha.
Kungofanana nechero mechanical chikamu, cheki valve ine hupenyu hwebasa uye inogona kupfeka uye kubvaruka. Debris ndiye muvengi wekutanga. Dombo diki kana chidimbu chegrit kubva patsime remvura chinogona kunamatira pakati pedhisiki nechigaro, ichichibata chakavhurika uye ichibvumira kudzoka kumashure. Nekufamba kwenguva, chitubu chinogona kurasikirwa nekunetsana kwacho, kunyanya mumasisitimu ane kazhinji pombi bhasikoro. Izvi zvinotungamirira kuchisimbiso chisina simba kana kuvhara zvishoma nezvishoma. Iyo rabha chisimbiso pachayo inogona zvakare kuderera kubva pakufumurwa kwemakemikari kana kungoita zera, kuita brittle uye kuputika. Pandakakurukura izvi naBudi, akaziva kuti kupa mavharuvhu emhando yepamusoro ane simba resimbi isina zvitubu uyezvakasimba zvisimbisoinzvimbo huru yekutengesa. Haisi yekungosangana nemutengo wepoindi; ndezvekupa kuvimbika kunodzivirira misoro yeramangwana kune yekupedzisira-mushandisi.

Chii chinangwa chevhavha yakatakura chitubu?
Iwe unoona izwi rekuti "spring-loaded" asi unoshamisika kuti chii chainopa. Kushandisa iyo isiriyo yevharuvhu mhando inogona kutungamira mukusashanda kana kukuvadza kune yako pombi system kubva ku shockwaves.
Chinangwa chevharuvhu yakatakura chitubu, senge cheki cheki, ndeye kushandisa simba rechitubu kuita otomatiki uye nekukurumidza kuita. Izvi zvinogonesa kukurumidza, chisimbiso chakasimba pakuyerera uye zvinobatsira kudzivirira kukuvadza kwesando yemvura nekuvhara kusati kwatanga kuyerera kusati kwawedzera simba.
Chitubu chinenge chiri injini inopa simba repakati pevhavha pasina rubatsiro rwekunze. Inobatwa mune yakamanikidzwa mamiriro, yakagadzirira kuita ipapo ipapo.
