Gawo loyendetsa valavu molingana ndi mawonekedwe a valve ndi zofunikira za ogwiritsa ntchito, pogwiritsa ntchito chogwirira, turbine, magetsi, pneumatic, etc., akhoza kutengera momwe zinthu zilili komanso zofunikira za wogwiritsa ntchito kusankha njira yoyenera yoyendetsera galimoto.

Izi mndandanda wa mankhwala valavu mpira malinga ndi mmene zinthu zilili sing'anga ndi payipi, ndi zofunika zosiyanasiyana owerenga, kamangidwe ka kupewa moto, odana malo amodzi, monga dongosolo, kukana kutentha ndi kutentha otsika akhoza kuonetsetsa valavu pansi zinthu zosiyanasiyana nthawi zambiri. ntchito, chimagwiritsidwa ntchito gasi, mafuta, mafakitale mankhwala, zitsulo, zomangamanga m'matauni, kuteteza chilengedwe, mankhwala, chakudya ndi mafakitale ena.

Mawonekedwe

• Ma valve otsatizana amagwiritsa ntchito zitsulo zopangira zitsulo kapena zitsulo zotayidwa ngati thupi lawo.Kapangidwe kake kangakhale koyandama koyandama kapena zothandizira zamtundu wa trunnion.
• Makina olondola kwambiri amabweretsa mpira wapamwamba ndi kulumikizana kwapampando kuti atseke zotsekeka kuti zigwirizane ndi kutayikira kwa ANSI B16.104 dass VI.
• Mayendedwe amtundu woyandama wokwera ndi wapadziko lonse lapansi.Mtundu wa Trunnion mounted ndi wozungulira kwambiri wokhala ndi ma block-ndi-kutulutsa magazi.
• Ntchito zodalirika zokhala ndi torque yocheperako: Mpando wokhala ndi diaphragm spring umakhala wolumikizana kwambiri ndi mpira kutsimikizira kusindikizidwa kolimba ngakhale kutsika pang'ono.Izi zimabweretsa ma torque otsika komanso otseka.
• Chitetezo pamoto: Kuphatikiza mipando yazitsulo ndi zosindikizira za graphite zimatsimikizira kuti chitetezo cha moto chikhoza kutetezedwa.
• Kutentha kwapamwamba kwambiri kwa ntchito kumafika pa 550°C (1022° F).Mpira ndi mpando zowumitsidwa ndi kuwombana kothamanga kwamlengalenga.Ndipo kuuma kumakumana ndi HRC 70-72.
• Kuthetsa malumikizidwe:DIN kapena ANSI flange, matako weld kapena socket weld.
