Abstract
The utility model relates to a new O-ring groove and contains an O-ring groove and an O-ring assembled to the groove. The utility model is characterized in that the ratio of the depth of the O-ring groove and the diameter of the cross section of the O-ring is 0.63-0.66; the sectional area ratio of the o-ring and O-ring groove is 0.88-0.92. The ratio of the depth of the O-ring groove and the diameter of the cross section of the O-ring is 0.65; the sectional area ratio of the O-ring and O-ring groove is 0.90. The advantages of the utility model are that: the sectional area of the O-ring groove is smaller after adopting the method, therefore, the O-ring will be fully held down and the static sealing surface will not leak, thereby guaranteeing a normal application of a pump.
Description
Technical field
The utility model relates to a kind of O-ring seals groove, particularly a kind of new O shape seal groove.
Background technique
In order to have prevented that press liquid from leaking between two static seal faces, between the static seal face, add rubber o-ring, so that O-ring seals uses in water pump is very many, almost every pump all will use.The size of the groove of dress O-ring seals also has requirement, originally all be to design with reference to the size that " GB3452.3-88 " dies, but find that in use these sizes are all bigger than normal, adorned between two static seal faces of O-ring seals and also can leak, thereby influenced the normal use of water pump.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above of O-ring seals groove self structure in the prior art, and a kind of new O shape seal groove is provided.The utility model designs a kind of new O shape seal groove, comprise O-ring seals groove, the O-ring seals that is assembled, it is characterized in that: the ratio of the degree of depth of O-ring seals groove and the cross-sectional diameter of O-ring seals is 0.63-0.66, and the ratio of the sectional area of the sectional area of O-ring seals and O-ring seals groove is 0.88-0.92.The ratio of the degree of depth of O-ring seals groove and the cross-sectional diameter of O-ring seals is 0.65, and the ratio of the sectional area of the sectional area of O-ring seals and O-ring seals groove is 0.90.The utility model has the advantages that the sectional area that adopts O-ring seals groove after this method all than original little, O-ring seals will fully be compressed like this, just can not leak between the static seal face, has guaranteed the normal use of water pump.
Description of drawings
Accompanying drawing 1 is an O-ring seals groove structural representation of the present utility model.
Accompanying drawing 2 is an O-ring seals structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
Comprise O-ring seals groove 1, the O-ring seals 2 that is assembled, it is characterized in that: the degree of depth 3 of O-ring seals groove 1 is 0.63-0.66 with the ratio of the cross-sectional diameter 4 of O-ring seals 2, and the ratio of the sectional area 5 of the sectional area of O-ring seals 2 and O-ring seals groove 1 is 0.88-0.92.Preferably the degree of depth 3 of O-ring seals groove 1 is 0.65 with the ratio of the cross-sectional diameter 6 of O-ring seals 2, and the ratio of the sectional area 5 of the sectional area of O-ring seals 2 and O-ring seals groove 1 is 0.90.The sectional area 5 that adopts O-ring seals groove 1 after this method is all than original little, and O-ring seals 2 will fully be compressed like this, just can not leak between the static seal face, has guaranteed the normal use of water pump.
Claims (2)
