Abstract
The utility model provides a scribble fluorine rubber gasket for exhaust gas recirculation valve, includes the gasket body, pipeline hole is seted up at gasket body middle part, and the connecting hole is seted up at both ends, pipeline hole peripheral surface sets up round elastic coating. Preferably, the elastic coating is a fluororubber coating and is arranged on the peripheral surface of the pipeline hole for a circle by a silk-screen printing process. Compared with the prior art, the utility model discloses following beneficial effect has: after the elastic coating is added, the rough flange surface on the exhaust gas recirculation valve can be better sealed by utilizing the good compression resilience performance of the elastic coating; although the structure is simple, the effect is very good, and the problem of air leakage can be thoroughly solved on the premise of not increasing the manufacturing cost of the exhaust gas recirculation valve.
Description
Technical Field
The utility model relates to a gasket, especially a scribble fluorine rubber gasket for exhaust gas recirculation valve belongs to valve technical field.
Background
The existing rubber gasket for the exhaust gas recirculation valve adopts a two-layer SUS301 stainless steel rib pressing structure. Such gaskets often leak during use. The applicant has analyzed that the problem arises in exhaust gas recirculation valves that, due to the manufacturing process, the overall surface is rough, which results in a non-tight fit of the rubber gasket to the rough flange surface.
Therefore, from the aspect of cost, the rubber gasket is optimized properly by the applicant absolutely to enhance the matching between the rubber gasket and the rough flange surface on the exhaust gas recirculation valve, so as to avoid the phenomenon of air leakage.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a scribble fluorine rubber gasket for exhaust gas recirculation valve to stop the gas leakage phenomenon.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
the utility model provides a scribble fluorine rubber gasket for exhaust gas recirculation valve, includes the gasket body, pipeline hole is seted up at gasket body middle part, and the connecting hole is seted up at both ends, pipeline hole peripheral surface sets up round elastic coating. Preferably, the elastic coating is a fluororubber coating and is arranged on the peripheral surface of the pipeline hole for a circle by a silk-screen printing process. Compared with the prior art, the utility model discloses following beneficial effect has: after the elastic coating is added, the rough flange surface on the exhaust gas recirculation valve can be better sealed by utilizing the good compression resilience performance of the elastic coating; although the structure is simple, the effect is very good, and the problem of air leakage can be thoroughly solved on the premise of not increasing the manufacturing cost of the exhaust gas recirculation valve.
Preferably, the gasket body is of a two-layer SUS301 stainless steel rib structure.
Drawings
Fig. 1 is a top view of the present invention.
Fig. 2 is a front view of the present invention.
Reference numerals: the gasket comprises a gasket body 1, a connecting hole 2, a pipeline hole 3 and an elastic coating 4.
Detailed Description
The present invention will be further described with reference to the following examples, which are only some, but not all, of the examples of the present invention. Based on the embodiments in the present invention, other embodiments used by those skilled in the art without creative work belong to the protection scope of the present invention.
Example (b):
the utility model provides a scribble fluorine rubber gasket for exhaust gas recirculation valve, includes gasket body 1, pipeline hole 3 is seted up at 1 middle part of gasket body, and connecting hole 2 is seted up at both ends, the peripheral surface in pipeline hole 3 sets up round elastic coating 4.
The elastic coating 4 is a fluororubber coating and is arranged on the peripheral surface of the pipeline hole 3 for a circle by a silk-screen printing process.
The gasket body 1 adopts a two-layer SUS301 stainless steel rib pressing structure.
