Abstract
The utility model discloses a strutting-type dual-gate-disc flat plate valve. The strutting-type double-gate-disc flat plate valve comprises a valve body. A valve rod and a strutting-type dual-gate-disc are arranged inside the valve body, a valve cover and a support are arranged on the valve body, lower sealing packing is arranged between the valve rod and the valve cover, upper sealing packing is arranged between the valve rod and the support, a sealing grease injection cavity is formed between the upper sealing packing and the lower sealing packing, the sealing grease injection cavity is connected with an injection channel, and an injection valve is arranged on the injection channel. The strutting-type dual-gate-disc flat plate valve has the advantages of being good in sealing effect between the valve rod and the valve cover in a use process, not prone to leak, capable of enabling adding sealing grease to be added according to needs in the use process, good in sealing effect, and convenient to maintain.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of bracing type double-flashboard flap type.
Background technique
All can use bracing type double-flashboard flap type on the pipelines such as water, steam, oil, the structure of existing bracing type double-flashboard flap type comprises: valve body, be provided with valve rod and bracing type double-flashboard in valve body, be provided with valve gap and support on valve body, between valve rod and valve gap, be provided with stuffing box packing.In use the sealing effect between valve rod and valve gap is bad, and maintenance is inconvenient.
Summary of the invention
