Abstract
The utility model discloses a leak-proof isolating valve which comprises an isolating valve body and a sealing surface, wherein the sealing surface is arranged on the isolating valve body and extends towards the outer side of the isolating valve body; and a sealing groove is formed in one side surface, contacted with a valve block, of the sealing surface. The section of the groove is triangular. The leak-proof isolating valve has the advantages that the sealing groove is added at the shoulder of the sealing surface, the sealing surface and the valve block are properly sealed after assembly, and the external leakage is avoided.
Description
Technical field
The utility model relates to automobile manufacturing field, particularly a kind of leakage-preventing separating valve for automobile ABS/ESC.
Background technique
When separating valve cut out, sealing surface can only rely on pressure medium to seal, and the valve seat that namely relies on pressure medium that the sealing surface of flashboard is pressed to opposite side guarantees the sealing of sealing surface, selfsealings that Here it is.Most of gate valve is to adopt forced seal, namely during valve closing, rely on external force by force flashboard to be pressed to valve seat, to guarantee the sealing of sealing surface.And present at separating valve with valve is packaged does not form effectively sealing after joining, outside situation about revealing is arranged in the time of after assembling.
The model utility content
The purpose of this utility model is to provide a kind of leakage-preventing separating valve that can provide with valve piece good sealing property.
For solving the problems of the technologies described above, the leakage-preventing separating valve of the utility model comprises: the separating valve body; Sealing surface, described sealing surface are arranged on the described separating valve body, and described sealing surface extends towards the outside of described separating valve body; Be provided with sealed groove at described sealing surface with a side that contacts of valve piece.The cross section of described groove is triangle.
The leakage-preventing separating valve of the utility model has increased sealed groove at the sealing surface shoulder, assembles rear and valve piece good seal, avoids the outside generation of revealing.
Description of drawings
Fig. 1 is the leakage-preventing separating valve structural representation of the utility model;
Fig. 2 is the leakage-preventing separating valve sealed groove of the utility model cross section partial enlarged drawing;
Description of reference numerals in the leakage-preventing separating valve accompanying drawing of the utility model:
1-separating valve body 2-sealing surface 3-sealed groove
Embodiment
Below in conjunction with accompanying drawing the leakage-preventing separating valve of the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the leakage-preventing separating valve of the utility model comprises: separating valve body 1; Sealing surface 2, sealing surface 2 are arranged on the separating valve body 1, and sealing surface 2 extends towards the outside of separating valve body 1; Being provided with the cross section at sealing surface 2 with the shoulder of a side that contacts of valve piece is leg-of-mutton sealed groove 3.
The leakage-preventing separating valve of the utility model has increased sealed groove at the sealing surface shoulder, assembles rear and valve piece good seal, avoids the outside generation of revealing.
The preferred embodiment of below the utility model having been created specifies, but the utility model is created and is not limited to embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the utility model creative spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
