[CN 201710202650.8] Title of Control System with Exhaust Gas Circulation for Press Dry Clutch Brake: Application Number of Control System with Exhaust Gas Circulation for Press Dry Clutch Brake: CN 201710202650.8 Applicant: Yangli Group Co., Ltd. Application Date: 2017-3-30 Patent Type: Application for Invention The present invention discloses a control system with exhaust gas circulation for press dry clutch brake in the technical field of press control, it includes a controller, an air control device and a cooling device for cooling the friction block. The air control device includes a main air source. The main air source enters the air storage tank through a one-way valve and a pressure regulating valve in turn. The air storage tank has two outlets, one outlet is connected to the inlet of the double valve. The outlet of the double valve is divided into two channels. One channel is connected to the brake through the one-way throttle valve, and the other through the clutch 2. the three-way valve, the inlet of the one-way throttle valve 1 and the exhaust port of the two-position three-way valve 2 are connected to the air storage tank through the electronically controlled one-way valve 1; the other outlet is connected to the cooling device; the clutch and the brake are equipped with temperature sensors, The controller controls the power failure of the double valve, the two-position three-way valve 2 and the electronically controlled one-way valve 1 and the operation of the cooling device.
