Valavu ndi chipangizo chowongolera kayendedwe ka madzi kapena gasi pakuyenda.Valavu yachitetezo ndikulephera kwachitetezo, cholinga chake ndikuwonetsetsa kuti payipi itetezedwa.Mwachitsanzo, valavu yopumira (PRV) ngati mtundu umodzi wa valavu yotetezera yomwe imatulutsa zinthu kuchokera ku chotengera chopondereza, boiler, kapena dongosolo lina pamene kupanikizika kapena kutentha kumadutsa malire omwe adakhazikitsidwa.

Msika wama valve otetezeka ukhoza kugawidwa ndi zinthu, kukula, mafakitale ndi dera.Malinga ndi zida zosiyanasiyana zomwe zimagwiritsidwa ntchito, msika wamagetsi oteteza chitetezo ukhoza kugawidwa muzitsulo zosapanga dzimbiri, chitsulo chosapanga dzimbiri, kutentha pang'ono, aloyi ndi mitundu ina, zitha kugwiritsidwa ntchito kwambiri mumafuta ndi gasi, mphamvu, mphamvu, madzi ndi madzi onyansa, mankhwala, mankhwala. , mafakitale a migodi, chakudya ndi zakumwa.

Udindo wofunikira wa valavu yachitetezo pamafakitale, kuchuluka kwa kufunikira kuchokera kumakampani amafuta ndi gasi, komanso kukula kwamagetsi amagetsi a nyukiliya ndizinthu zazikuluzikulu zolimbikitsa kukula kwa msika wa valve yachitetezo.Msika womwe ukukulirakulira wa ma valve oteteza chitetezo umayendetsedwa ndi kufunikira kosalekeza kosintha ma valve otetezeka komanso kugwiritsa ntchito osindikiza a 3D pamizere yopanga.Kumbali ina, kukwera mtengo kopanga kudzalepheretsa kukula kwa msika uno.

COVNA ikupanganso nthawi zonse ndikupanga zatsopano kuti ipange ndikupereka ma valve otetezeka apamwamba kuti akulitse msika wapadziko lonse lapansi.
