The gasket seal being arranged at sky pump and the connecting end surface of engine is common rubber sheet gasketing, and poor sealing effect is easy to damage
The problem of.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of gasket seal, including shim body, the position that the first fixation hole on the pump housing is corresponded in the shim body are opened
The position for having first through hole, and corresponding to the second fixation hole on the pump housing in shim body is provided with the second through-hole, in the shim body
The position of the corresponding enterprising oilhole of the pump housing is provided with first and walks oil hole, and corresponds to the position of outage on the pump housing in shim body and be provided with
Second walks oil hole, and the shim body includes internal casing play and the sealant that is coated on casing play, the sealant
Protrude above and be formed with sealing strip, the sealing strip is closing structure, and define a sealing area, described first walk oil hole,
Second, which walks oil hole, is opened in the sealing area.
As a kind of preferred embodiment of the utility model, it is provided on the sealant of the shim body tow sides close
Strip of paper used for sealing.
It is located in sealing area as a kind of preferred embodiment of the utility model, on the sealant and is provided with for by the
One walks oil hole, second walks oil hole and seal off the spacer bar that comes.
As a kind of preferred embodiment of the utility model, the sealing strip is 3, including the first internal sealing strip,
The second sealing strip being centered around outside the first sealing strip and the third sealing strip being centered around outside the second sealing strip.
As a kind of preferred embodiment of the utility model, gap is provided between first sealing strip and the second sealing strip
1mm~2mm is provided with gap 1mm~2mm between second sealing strip and third sealing strip.
As a kind of preferred embodiment of the utility model, the protrusion height of the sealing strip is 0.1mm~0.2mm.
As a kind of preferred embodiment of the utility model, the sealant is structure as a whole with sealing strip.
As a kind of preferred embodiment of the utility model, the sealant is fluororubber layer, and the sealing strip is fluorubber
Item.
As a kind of preferred embodiment of the utility model, the casing play is iron sheet layer.
The beneficial effects of the utility model are, sealant is coated on by a kind of gasket seal by setting casing play
On casing play, and then the intensity of shim body can be effectively improved, and sealant protrudes above the sealing strip to be formed, not only act as increase
The effect of intensity, and sealing effect is further improved, structure is simple, is easily achieved.
