Valovu Yampira Wokwanira Mokwanira
Mafotokozedwe Akatundu
Mpira wa valavu ya mpira woyandama umathandizidwa momasuka pa mphete yosindikiza. Pansi pa mphamvu yamadzimadzi, imakhala yolumikizidwa kwambiri ndi mphete yosindikizira yakumtunda kuti ipangitse chisindikizo cham'mphepete mwa mtsinje wokhazikika.
Mpira wa valve wokhazikika wokhala ndi shaft yozungulira mmwamba ndi pansi, umayikidwa mu mpirawo, choncho, mpirawo umakhazikika, koma mphete yosindikizira ikuyandama, mphete yosindikizira yokhala ndi kasupe ndi kuthamanga kwamadzimadzi kumtunda kwa mpira, kumapeto kwa mtsinje. chisindikizocho. Chimagwiritsidwa ntchito pazovuta kwambiri komanso ntchito zazikulu.
Gawo loyendetsa valavu molingana ndi mawonekedwe a valve ndi zofunikira za ogwiritsa ntchito, pogwiritsa ntchito chogwirira, turbine, magetsi, pneumatic, ndi zina zotero, zikhoza kukhazikitsidwa pazochitika zenizeni ndi zofunikira za ogwiritsa ntchito kusankha njira yoyenera yoyendetsa galimoto.
Izi mndandanda wa mankhwala valavu mpira malinga ndi mkhalidwe wa sing'anga ndi payipi, ndi zofunika zosiyanasiyana owerenga, kamangidwe ka kupewa moto, odana ndi malo amodzi, monga dongosolo, kukana kutentha ndi kutentha otsika akhoza kuonetsetsa valavu pansi pa zinthu zosiyanasiyana nthawi zambiri. ntchito, chimagwiritsidwa ntchito gasi, mafuta, mafakitale mankhwala, zitsulo, zomangamanga m'matauni, kuteteza chilengedwe, mankhwala, chakudya ndi mafakitale ena.
