As depicted in figs. 1 and 2, what the utility model provided comprises washer body 1 for the packing ring sealing intake manifold, top and the bottom of described washer body 1 are respectively arranged with two seals muscle 2, described sealed muscle 2 is for being arranged on the described top of washer body 1 and the annular projection of bottom, the madial wall of described washer body 1 is provided with the first spacing preiection 31 equably, the outer side wall of described washer body 1 is provided with the second spacing preiection 32 equably, described washer body 1, described sealed muscle 2, described first spacing preiection 31 and described second spacing preiection 32 are made by fluorine rubber.
The utility model is provided with two seals muscle 2 respectively on the top of described washer body 1 and bottom, washer body 1 can be fixed in intake manifold groove by described two seals muscle 2 better, described washer body 1 is made stably to be arranged in intake manifold groove, improve the stability of packing ring, thus effectively can avoid when compressing the problem causing the pressure distribution inequality on sealing surface because of packing ring run-off the straight, thus improve the sealing effect of water pump packing ring.
The utility model arranges the packing ring of two seals muscle 2 on washer body 1, define the end face with two circle sealing surfaces by this, double seal face can not only make the pressure uniform on packing ring distribute, if when wherein one sealed muscle 2 produces defect or breaks, another road sealed muscle 2 can also continue to maintain sealing, effectively improves the reliability of washer sealing.
In addition, the utility model also adopts fluorine rubber to prepare described washer body 1, described sealed muscle 2, described first spacing preiection 31 and described second spacing preiection 32, and fluorine rubber has the performances such as heat-resisting, corrosion-resistant, contributes to the working life of improving packing ring.
Certainly, in order to play the effect of sealing better, the utility model can also carry out accommodation to other component surface roughness coordinated with the utility model packing ring or planeness, obtains better sealing effect by this.
As a kind of preferred version of the present utility model, on the top that described two seals muscle 2 is arranged on described washer body 1 by the utility model abreast and bottom, thus ensure that the sealing surface that described sealed muscle 2 is formed can not produce intersection or overlap, ensure the reliability of washer sealing by this.Those skilled in the art it should be noted, the utility model is not specifically limited the distance between described two seals muscle 2, on the basis ensureing sealing effect, those skilled in the art can according to the width of washer body 1 top and bottom, accommodation is done to the distance of described two seals muscle 2, repeats no more herein.
