Ceramic double gate valve performance characteristics and technical parameters
Ceramic double gate valve, also known as ceramic parallel double gate valve or dry gray valve, is a kind of ceramic gate valve. Therefore, its structure and working principle consistent with the ceramic gate valve, the opening and closing body (valve plate) by the valve stem to move the valve seat sealing surface for lifting movement, can be connected or cut off the fluid channel. When the valve is partially open, eddy current is generated on the back of the ram, easily causing erosion and vibration of the ram and easily damaging the sealing surface of the valve seat, which is difficult to repair. Usually, it is suitable for not requiring frequent opening and closing and keeping the ram full open or full Closed condition. The ceramic rail strip provided on the inner side of the bonnet and the auxiliary spring provided in the three-way valve core can effectively prevent the left and right shutters from moving against the ceramic track strip without any leakage so as to ensure that the valve body Of the normal operation, the utility model is simple in structure, easy to install and use.
