Background Art

Blind plate valve, also known as blind plate or plug valve, is a type of valve body used to block fluid in a pipeline system. It is usually used for maintenance, repair or sealing of fluid in a pipeline system so that the fluid flow can be isolated during operation. Blind plate valve is widely used in chemical, petroleum, natural gas, pharmaceutical, food and beverage industries.

When the existing blind plate valve is in use, the blind plate is controlled to prevent the medium from passing through, which is convenient for maintaining and repairing the pipeline. However, when the medium is blocked, the blind plate is prone to poor sealing, and leakage is prone to occur in the closed state. In addition, the blind plate needs to be manually controlled, which is not convenient when controlling the opening and closing. The valve body is less corrosive when in use, and the service life of the valve body is short.

Therefore, the utility model provides a corrosion-resistant blind plate valve to solve the problems raised in the above background technology.
