Description

Technical Field

[0001] The utility model relates to the technical field of double-gate valves, in particular to an elastic double-gate valve core. Background Technique

[0002] The double-gate valve is applicable to the pipelines with media such as water and sewage as a closed-circuit device, and is not allowed to be used for regulating flow and emptying. It is widely applicable to industries such as petroleum, chemical industry, pharmacy, and electric power. The parallel double-gate valve is a kind of ceramic gate valve. Therefore, its structure and working principle are the same as those of the gate valve. Its opening and closing body drives the valve seat sealing surface to make a lifting movement by the valve stem, and can connect or cut off the fluid passage. When the valve is partially opened, eddy currents are generated on the back of the gate plate, which is easy to cause erosion and vibration of the gate plate, and is also easy to damage the valve seat sealing surface, and it is difficult to repair. It is usually applicable to the working conditions that do not need to be opened and closed frequently and keep the gate plate fully open or fully closed.

[0003] In the technical field of double-gate valves, during the use of the existing double-gate valves, during the opening and closing of the valves, the gate plates will rub against the inner wall of the shell. After a long time, the gate plates are easily worn, resulting in poor sealing of the gate plates and affecting normal use.

[0004] Therefore, it is necessary to provide an elastic double-gate valve core to solve the above technical problems. Content of the Utility Model
