Imihlahlandlela yokukhetha nokubuyiselwa kwevalvu iindlela ezihle khulu

Ukuqakatheka kokukhethwa kwevalvu: Ukukhethwa kwezakhiwo zamavalvu wokulawula kunqunywa ngokucabangela ngokubanzi izinto ezifana nomphakathi osetjenzisiweko, amazinga womtjhiso, ukugandeleleka okuphezulu nokwehla, izinga lokugeleza, izakhiwo ezibonakalako nezamakhemikhali zendawo, nokuhlanzeka kwendawo. Ukulunga nokunengqondo kokukhethwa kwesakhiwo sevalvu kuthinta ngqo ukusebenza, ikghono lokulawula, ukuzinza komthetho, kanye nepilo yomsebenzi.

I. Amapharamitha wenqubo:

1. Phakathi'sIbizo.
2. Ukuminyana okuphakathi, ukunamathelana, amazinga womtjhiso, nokuhlanzeka kwendawo (ngezinto ezincani).
3. Iimpawu ze-physicochemical ze-Medium: Ukugqwala, ubuthi, kanye ne-pH.
4. Amazinga wokugeleza aphakathi: Ubukhulu, obujayelekileko, nobuncani
5. Umfutho ophezulu nangaphasi kwe-Valve: Ubukhulu, Obujayelekileko, Obuncani.
6. Ukunamathelana okuphakathi: lokha nakunamathelana okuphezulu, kuthinta khulu ukubalwa kwenani le-Cv.

Amapharamitha la asetjenziselwa ukubala ububanzi bevalvu etlhogekako, inani le-Cv elilinganisiweko, namanye amapharamitha wobukhulu, kanye nokuthola izinto ezifaneleko okufanele zisetjenziselwe ivalvu.

II. Imingcele yokusebenza:

1. Iindlela zokusebenza: igezi, umoya,i-elector-hydraulic, hydraulic.
2. Ivalve'simisebenzi: umthetho, ukuvala, kanye nomthetho ohlanganisiweko&ukuvala.
3. Iindlela zokulawula:Umfakisibawo, i-solenoid valve, i-pressure reducing valve.
4. Isidingo sesikhathi sokwenza.

Ingcenye le yamapharamitha isetjenziselwa khulu ukuthola ezinye iinsetjenziswa ezisizako ezitlhoga ukulungiswa ukuhlangabezana neemfuneko zokusebenza kwevalvu.

III. Imingcele yokuvikela ukuqhuma:

1. Isilinganiso sokuvikela ukuqhuma.
2. Izinga lokuvikeleka.

IV. Irhelo lamapharamitha wezebhoduluko newokuguquguqukako

1. Izinga lokutjhisa elizungezeko.
2. Imingcele yamandla: umfutho wokuphakelwa komoya, umfutho wokuphakelwa kwamandla.

Iinqabo zokuTjhugulula amaValvu

Ukuqinisekisa ukutjhugululwa kwevalvu okuhambisanako nokukhandela imiraro yokufaka, sibawa unikele ngamazinga alandelako. Ukuhlukahluka hlangana nabakhiqizi namadizayini kungadosela ekutheni kube nokulingana kuhle nofana isikhala esinganeleko. EI-TWS, izazi zethu zizokwenza isisombululo ngokuncoma ivalvu efaneleko—ivalvu yevivane, ivalvu yesango, namkhaivalvu yokuhlola—ngeemfuneko zakho, ukuqinisekisa ukusebenza nokuhlala isikhathi eside.
