The invention provides a self-reliance type cinder valve which comprises a valve body, a valve cover, a valve base, and a valve plate, wherein the valve body is connected with the valve cover through a bolt; the valve base is positioned on the valve cover, the valve base and a conical surface of the valve plate form a seal deputy, the valve plate is fixedly connected with a guide rod, a guide sleeve is fixed in the valve body, and the guide rod passes through the guide sleeve; and the lower part of the guide rod is provided with a pin roll, a valve shaft penetrates through the valve body, a shifting fork is fixed on the valve shaft in a valve body cavity, the pin roll is positioned in an open groove, a connecting rod is arranged on the valve shaft arranged outside of the valve body, and the other end of the connecting rod is provided with a heavy punch. The self-reliance type cinder valve provided by the invention has the beneficial effects of simple structure and reliable seal; the switch on / off of a valve is automatically controlled through the gravity of a material, any power drive is not needed, thereby saving energy consumption.
Description
technical field [0001] The invention relates to a valve device, in particular to a valve for unloading ash. Background technique [0002] The ash unloading valve currently used in the ash unloading system of the metallurgical industry generally adopts the form of a ball valve or a bell valve. The common feature is that the valve is operated by an electric device or a pneumatic device. Power supply, pneumatically operated valves, air source, and solenoid valves are required for control, which is costly and consumes precious energy. Contents of the invention [0003] In order to overcome the shortcomings of the existing ash unloading valve control system, which are complex, costly and consume energy, the present invention provides a self-operated ash unloading valve. [0004] The technical solution adopted by the present invention to solve the technical problem is a self-operated ash unloading valve, which includes a valve body, a valve cover, a valve seat, and a valve plat...
