valavu yodziyendetsa yokha ya piston

valavu yodziyendetsa yokha ya piston

Kufotokozera Kwachidule:

Piston type self-operated regulator yomwe imatha kusintha kukakamizidwa ngati mtengo wake ndi mphamvu zake zapakatikati komanso popanda mphamvu zakunja. Ubwino wamtundu wa Piston wodziyendetsa wokha ndikuti ukhoza kukhala woyenera malo ogwirira ntchito opanda mphamvu. ndipo palibe zida za pneumatic zomwe zilipo, zowonjezera, Piston type self-operated regulator ikhoza kupulumutsa mphamvu kwa wogwiritsa ntchito mapeto, ndipo kupanikizika kumasinthidwa mkati mwazomwe zilipo.

Piston type self-operated regulator yomwe imatha kusintha kukakamizidwa ngati mtengo wake ndi mphamvu zake zapakatikati komanso popanda mphamvu zakunja. Ubwino wamtundu wa Piston wodziyendetsa wokha ndikuti ukhoza kukhala woyenera malo ogwirira ntchito opanda mphamvu. ndipo palibe zida za pneumatic zomwe zilipo, zowonjezera, Piston type self-operated regulator ikhoza kupulumutsa mphamvu kwa wogwiritsa ntchito mapeto, ndipo kupanikizika kumasinthidwa mkati mwazomwe zilipo.

Piston type self-operated regulator ili ndi mitundu iyi kutengera momwe amagwirira ntchito:
ZZYP(mtundu wampando umodzi), ZZYM(mtundu wa mikono) ndi ZZYN(mtundu wa mipando iwiri), ndi PPiston type self-operated regulator ilinso ndi zovundikira zitatu zosiyanasiyana monga wamba, khosi lalitali ndi mtundu wozizirira.Pazinthu zosiyanasiyana, chowongolera chodziyendetsa chamtundu wa PPiston ndi piston actuator, ndipo valavu yodziyendetsa yokha ili ndi mitundu itatu yolumikizira: film/piston/bellows.

Piston type self-operated regulator ili ndi zabwino zina monga kuwongolera mwanzeru komanso kolondola, kutenga malo ang'onoang'ono ndi ntchito yosavuta ndipo imagwiritsidwa ntchito kwambiri pakuwongolera mpweya, nthunzi kapena madzi mumafuta, mankhwala, mphamvu yamagetsi, zitsulo, chakudya, nsalu, makina, zomangamanga zomangamanga.

Piston type self-operated regulator idapangidwa ndikupangidwa molingana ndi muyezo wa AMSE/API/BS/DIN/GB
