It is well known that gasket is made of paper, rubber tissue or copper sheet, it is placed on to strengthen the material of sealing between two planes,
For fluid leakage is prevented to be arranged on the sealing element between static seal face, apply and its extensive.
At present, existing traditional gasket there are one it is serious the shortcomings that, be exactly easily to loosen, if gasket use is in no safety problem
Equipment on it doesn't matter, if gasket use in the high equipment of safety requirements, easily cause major accident because of loosening.
It is therefore proposed that a kind of check washer is the problem of the invention to be studied.
The content of the invention
The main purpose of the application is to provide a kind of check washer, the problems such as existing conventional spacers to be overcome easily to loosen.
To realize aforementioned application purpose, the technical solution that the application uses includes：A kind of check washer mating makes including one
Upper gasket and lower gasket, the Upper gasket are annular gasket structure on one, and front of annular gasket structure is equipped on this
Several upper locking slots rotated in the forward direction, several upper locking slots are circumferentially uniformly sequentially arranged along upper annular gasket, ring on this
The reverse side of shape gasket construction is equipped with the upper locking teeth of several reverse rotations；The lower gasket is annular gasket structure, at this
The front of lower annular gasket structure is equipped with the lower locking slot of several reverse rotations, if being somebody's turn to do lower dry locking slot along lower annular gasket week
To being uniformly sequentially arranged, several lower locking teeths rotated in the forward direction are equipped in the reverse side of the lower annular gasket structure；In assembled state
Under, the reverse side of the Upper gasket and the reverse side of lower gasket are locked by upper locking teeth and lower locking teeth.
Further, the reverse side of the reverse side of the Upper gasket and lower gasket is equipped with location structure.
Further, the upper locking slot two sides are radial to circumferencial direction along circular piece central through hole center
Straight line.
Further, the lower locking slot two sides are radial to circumferencial direction along circular piece central through hole center
Straight line.
Further, the upper locking number of teeth amount on the Upper gasket is 16~20.
Further, the lower locking teeth quantity on the lower gasket is 16~20.
Further, the ratio of width circumferentially of the upper locking teeth and upper locking slot is 2:0.8~1.1；The lower locking
The ratio of width circumferentially of tooth and lower locking slot is 2:0.8~1.1.
By above technical solution, the advantageous effect of the application is：Good reliability of the present invention, by upper locking teeth and
The anti-loosing effect of lower gasket is effectively ensured in the engagement of lower locking teeth, in addition, the setting of upper locking slot and lower locking slot, ensures
Gasket and other connections between upper lower gasket are reliable.
