Isu tinowanzo funga nekudzidzira zvinoenderana nekuchinja kwemamiriro ezvinhu, uye kukura. Isu tinovavarira kuzadzikiswa kweakapfuma pfungwa nemuviri uye zvakare kurarama kwe2019 China New Design China Simudza Wafer Check Valve (GAH74H), Base pane bhizinesi pfungwa yeHunhu kutanga, tinoda kusangana nekuwedzera shamwari mushoko. uye isu tinovimba tinokupa yakanakisa chigadzirwa uye sevhisi kwauri.
Isu tinowanzo funga nekudzidzira zvinoenderana nekuchinja kwemamiriro ezvinhu, uye kukura. Isu tinovavarira kubudirira kwevakapfuma pfungwa nemuviri uye zvakare nekuraramiraCast Steel Check Valve,China Single Plate Check Valve , Kambani yedu iri kushanda nemusimboti wekushanda we "kutendeseka-kwakavakirwa, kushandira pamwe kwakagadzirwa, vanhu vanotarisana, kukunda-kuhwina kubatana". Tinovimba tinogona kuva nehukama hwehushamwari nemuzvinabhizimisi kubva kumativi ose enyika.
Kusimudza cheki valve inoreva vharuvhu inongovhura uye inovhara dhisiki zvichienderana nekuyerera kwepakati pachayo kudzivirira yepakati backflow, inozivikanwawo sevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha, nzira imwe chete, counterflow valve, uye back pressure valve. Cheki vharafu ivharuvhu otomatiki. Basa rayo guru nderekudzivirira yepakati backflow, reverse pombi uye dhiraivha mota, uye kuburitswa kwemidziyo yepakati. Cheki mavharuvhu anogona zvakare kushandiswa mumapaipi kupa anobatsira masisitimu uko kudzvanywa kunogona kukwira pamusoro pesimba rehurongwa. Cheki mavharuvhu anogona kukamurwa kuita swing cheki mavharuvhu (anotenderera zvinoenderana nepakati pesimba regiravhiti) uye simudza cheki mavharuvhu (achifamba achitevedza axis).
