Description
Technical Field
The utility model relates to an engine field especially relates to an integral explosion-proof diesel engine is sealed metal gasket for blast pipe.
Background
At present, the traditional exhaust pipe gasket is of a single-layer or double-layer structure, the common single-layer gasket does not have the capacity of compensating deformation, the expansion space of double layers is limited, namely, the compensation amount is not large, after the engine runs for a certain time, the exhaust pipe and the exhaust pipe gasket deform, the sealing performance between the exhaust pipe and the cylinder cover becomes poor, the compensation amount of the exhaust pipe gasket of the single-layer or double-layer structure is limited, and the air leakage phenomenon of the engine and even the serious fault problem of the gasket are caused.
The above background disclosure is only provided to aid understanding of the inventive concepts and solutions of the present invention, and it does not necessarily pertain to the prior art of this patent application, and it should not be used to assess the novelty and inventive aspects of this application without explicit evidence that such contents are disclosed at the filing date of this patent application.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an integral explosion-proof diesel engine is sealed metal gasket for blast pipe.
In order to realize the above purpose, the utility model discloses a technical scheme as follows:
the utility model provides an integral explosion-proof diesel engine is sealed metal gasket for blast pipe which characterized in that: the exhaust gas circulation device comprises an upper gasket and a lower gasket, wherein a plurality of exhaust gas circulation holes are respectively formed in the upper gasket and the lower gasket, the exhaust gas circulation holes are circular or square, a circle of flow groove is respectively formed beside an exhaust gas flow through hole of the upper gasket and the exhaust gas flow through hole of the lower gasket, and the upper gasket and the lower gasket are connected in a matched mode.
Furthermore, two screw holes are formed in the upper portion of the waste gas circulation hole.
Furthermore, a screw hole is formed in the lower portion of the exhaust gas circulation hole.
Furthermore, the upper gasket and the lower gasket are symmetrically connected, and the waste gas circulation holes and the flow grooves of the upper gasket and the lower gasket are corresponding.
Furthermore, a circle of ribs are formed between the chutes of the upper gasket and the lower gasket in a matching manner.
Furthermore, the upper gasket and the lower gasket are made of stainless steel.
Compared with the prior art, the utility model discloses an advantage and beneficial effect do:
the utility model discloses an integral blast pipe seal gasket that forms is connected by two gaskets adopts monolithic structure, fine solution the installation hidden danger of neglected loading, is equipped with the round rib by the waste gas flow through-hole simultaneously, can be fine realization the airtight sealing requirement, solved because of the ageing problem that appears gas leakage of long-time work gasket deformation, have with low costs, the installation is fast, deformability is big, the security is high, and longe-lived advantage.
