Abstract
The utility model relates to a kind of engine exhaust valve with heat filter, comprise left shell and right shell body, left shell and right shell body are by the cavity of integrally welded structure, on left shell, offer suction port, suction port arranged outside has heat filter, on heat filter, offer at least one hole corresponding with tapped hole on left shell, on right shell body, offer exhaust port, the bolt at the exhaust port place of right shell body is connected with guide plate, is provided with disassembly-type fire extinguishing web plate between the exhaust port of right shell body and guide plate.The engine exhaust valve with heat filter of the present utility model changes over easy structure, and at suction port place, heat filter is set, and heat-shielding performance between outlet valve and cylinder is improved, reduced the diffusion of temperature in outlet valve, sealability strengthens simultaneously, and cost of production is also low.
Description
Technical field
The utility model relates to a kind of Exhuster of engine, especially a kind of engine exhaust valve with heat filter.
Background technique
Existing engine exhaust valve with cylinder assembling place, air tight in order to guarantee in running, at the end face of two contacts, adding man-hour is all to have adopted higher precision to control, in order to prevent that in cylinder, the too high temperature of air-flow affects outlet valve, reduce working life, outlet valve all can adopt the length that increases gas exhaust piping, the wall thickness of reinforced platoon's air pipe is produced, thus, can be very high for outlet valve production required precision and cost of production, if cause loss in routine use, can have a strong impact on the sealability between outlet valve and cylinder, in machine lower can air displacement increase that run up, easily damage outlet valve.
Model utility content
The technical problems to be solved in the utility model is: for solving the problem of above-mentioned existence, provide a kind of engine exhaust valve with heat filter.
The utility model solves the technological scheme that its technical problem adopts: a kind of engine exhaust valve with heat filter, comprise left shell and right shell body, left shell and right shell body are by the cavity of integrally welded structure, on left shell, offer suction port, suction port arranged outside has heat filter, on heat filter, offer at least one hole corresponding with tapped hole on left shell, on right shell body, offer exhaust port, the bolt at the exhaust port place of right shell body is connected with guide plate, is provided with disassembly-type fire extinguishing web plate between the exhaust port of right shell body and guide plate.
Further, on heat filter, offer the through hole identical with air inlet port size.
Further, heat filter is graphite heat filter.
The beneficial effects of the utility model are, the engine exhaust valve with heat filter of the present utility model changes over easy structure, and at suction port place, heat filter is set, heat-shielding performance between outlet valve and cylinder is improved, reduced the diffusion of temperature in outlet valve, sealability strengthens simultaneously, and cost of production is also low.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. left shells in figure, 2. right shell body, 3. heat filter, 4. guide plate, 5. fire extinguishing web plate, 6. tapped hole.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
The engine exhaust valve with heat filter as shown in Figure 1, comprise left shell 1 and right shell body 2, left shell 1 and right shell body 2 are by the cavity of integrally welded structure, on left shell 1, offer suction port, suction port arranged outside has heat filter 3, on heat filter 3, offer at least one hole corresponding with tapped hole 6 on left shell 1, on right shell body 2, offer exhaust port, the bolt at the exhaust port place of right shell body 2 is connected with guide plate 4, is provided with disassembly-type fire extinguishing web plate 5 between the exhaust port of right shell body 2 and guide plate 4.
On heat filter 3, offer the through hole identical with air inlet port size, heat filter 3 is graphite heat filter 3, because material is softer, can play better cushioning effect, can effectively protect outlet valve, and sealability improves.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this model utility technological thought, carry out various change and modification completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
