The quantity of seal ring is 3, respectively the first face sealing ring, the second face sealing ring and third face sealing ring, the first face sealing
Ring, the second face sealing ring and third face sealing ring are in circular ring shape, and the diameter for the circular ring shape for being in is sequentially reduced, and the line is close
The quantity of strip of paper used for sealing is 2, respectively First Line sealing strip and the second linear sealing item, and it is close that the First Line sealing strip is located at the first face
Between seal ring, the second face sealing ring, the second linear sealing item is between the second face sealing ring and third face sealing ring；
The First Line sealing strip and the second linear sealing item are in petal end to end, First Line sealing strip and the second line
The section of sealing strip is in isosceles triangle, and the apex angle for the isosceles triangle for being in is α, and the α is 20 ~ 25 °；
The cylindrical middle part that the gasket monomer is in is equipped with through-hole, and the inner wall of the through-hole is equipped with positioning ring,
The positioning ring is in circular ring shape, and positioning ring is equipped with multiple locating notches, the locating notch semicircular in shape, multiple locating notches
Between in circumferential uniformly distributed；
Described two gasket monomers are symmetrical arranged in upper and lower, and pass through multiple air cushion phases between two gasket monomers
Even, the air cushion is cylindrical, and multiple air cushions are uniformly distributed between two gasket monomers；
Further, the spacing between first face sealing ring and the second face sealing ring and the second face sealing ring and third
Spacing between the sealing ring of face is equal；
Further, the consistency of thickness of first face sealing ring, the second face sealing ring and third face sealing ring.
The invention has the benefit that
A kind of spray head special sealing pad proposed by the present invention, including gasket main body, gasket main body is by two gaskets
Monomer is constituted, and the side of gasket monomer is equipped with the face sealing ring and linear sealing item of alternate setting, and face sealing ring concentric in changing more
Setting, for linear sealing item in petal end to end, the section of linear sealing item is in isosceles triangle, the configuration of the present invention is simple, design
Rationally, by linear sealing, with face, sealing is combined, and strengthens sealing effect, meanwhile, it is symmetrical arranged using dual MCU system, embeds air bag, protected
Enough elastic stresses are demonstrate,proved, and more lasting, guarantees that sealing effect is able to play a role for a long time, service life is also significantly prolonged
It is long.
Detailed description of the invention
