Abstract
The utility model discloses a blade for a sealing valve. The blade comprises a blade body, wherein two ends of the blade body are respectively provided with a vulcanized rubber sealing head; the end face of the sealing head is arc-shaped; one side of the sealing head is provided with independent large sawteeth; the other side of the sealing head is provided with first small sawteeth and second small sawteeth which are arranged in parallel; notches are reserved between the first small sawteeth and the second small sawteeth; and the notches are matched with the large sawteeth. The periphery of the end of the blade is firmly sealed, the friction can be reduced, the sealing property is improved, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of airtight valve and uses blade.
Background technique
The sealing of existing airtight valve generally can only be pasted rubber weather strip on the both sides of the length of blade direction of airtight valve, and the defective of this encapsulating method is to come off easily, thereby causes the termination of blade to seal.
The model utility content
The model utility purpose: the purpose of the utility model is in order to remedy the deficiency of existing technology, to provide a kind of and can strengthen sealing, and can reduce wear, and the airtight valve that prolongs the working life of airtight valve is used blade.
Technological scheme: a kind of airtight valve is used blade; Comprise blade body, described blade body two ends respectively are provided with the vulcanized rubber sealing head, and described sealing head end face is a circular arc; Sealing first side is single big sawtooth; Opposite side is the first little sawtooth and the second little sawtooth that is set up in parallel, and leaves recess between the described first little sawtooth and the second little sawtooth, and described recess is suitable with big sawtooth.
Beneficial effect: the utility model has adopted after such structure; Secure seal around the end of blade, and end face all do in the arc-shaped, can reduce between blade and the blade and blade termination and deckle board between friction; Increase the sealability of blade, also prolonged working life.
