Abstract
One not only high temperature resistant, resistance to chemical attack, heat shock resistance, high elastic modulus but also withstand voltage, erosion-resisting exhaust pipe seal gasket sheet.For reaching design object, exhaust pipe seal gasket sheet of the present utility model: comprise exhaust port and fixed hole, pad is welded by upper and lower two panels sheet metal and forms, it is characterized in that: the upper and lower two panels sheet metal liner of pad has one deck ceramic fiber, its feature: for without asbestos, fiber is long, slag ball is few, unit weight is little, intensity is large, good springiness, be convenient to the constructing operation such as die-cut, winding.Be applicable to heat insulation, the insulation under high temperature, sealing, electrical insulation, sound-absorbing, filtration etc., as a kind of novel lightweight refractory, exhaust pipe seal gasket sheet applied, asbestos product can be replaced, reach the object of energy-conserving and environment-protective.
Description
Technical field
This Shi Xin Xing Wataru and a kind of gasket seal, relate in particular to the erosion-resisting a kind of exhaust pipe seal gasket sheet of heat resisting and pressure resisting.
Background technique
The seal action of exhaust pipe seal gasket sheet is extremely important.Engine cylinder works under high temperature, high pressure, oil, aqueous corrosion environment, and when engine exhaust pipe is connected with cylinder, outlet pipe and cylinder exist deviation in planeness, and another effect of exhaust pipe seal gasket sheet is compensate.Gasket seal in the market mainly adopts asbestos packing sheet to make, and its defect is that this material easily produces harmful exhaust under hot operation, and working life is shorter.Ceramic fiber adopts wet therapy forming process to make, and has the performances such as high temperature resistant, resistance to chemical attack, heat shock resistance, high elastic modulus.Its feature for without asbestos, fiber is grown, slag ball is few, unit weight is little, intensity is large, good springiness, be convenient to the constructing operation such as die-cut, winding.Be applicable to heat insulation, the insulation under high temperature, sealing, electrical insulation, sound-absorbing, filtration etc., as a kind of novel lightweight refractory, exhaust pipe seal gasket sheet applied, asbestos product can be replaced, reach the object of energy-conserving and environment-protective.
Summary of the invention
For to the object of energy-conserving and environment-protective, the utility model design provides one not only high temperature resistant, resistance to chemical attack, heat shock resistance, high elastic modulus but also resistance toly reaches pressure, erosion-resisting exhaust pipe seal gasket sheet.For reaching design object, exhaust pipe seal gasket sheet of the present utility model: comprise exhaust port and fixed hole, pad is welded by upper and lower two panels sheet metal and forms, and it is characterized in that: the upper and lower two panels sheet metal liner of pad has one deck ceramic fiber.
Further, the upper and lower two panels sheet metal liner of pad has one deck ceramic fiber to be aluminum silicate fiber paper.
Further, exhaust port peripheral sealing position is provided with sheet metal bound edge.
Further, sheet metal bound edge thickness is 1. 18-1.28mm, and impaction state thickness is 1. 05-1. 15mm.
Accompanying drawing explanation
Fig. 1: the structural representation of the utility model embodiment.
Fig. 2: Fig. 1 partial sectional view.
Embodiment
Below in conjunction with accompanying drawing 1-2, embodiment of the present utility model is described further: the gasket seal on a kind of engine exhaust pipe as shown in Figure 1, upper and lower two ends arrange mounting hole 4 with pad, middle arranges through hole 2, pad is welded by upper and lower two panels sheet metal 3 and forms, and two panels sheet metal 3 used arc spot welding to fix up and down.
As shown in Figure 2: in the upper and lower two panels sheet metal 3 of pad, be lined with one deck ceramic fiber 6.
Above-described embodiment is only preferred embodiment of the present utility model, and all equalizations done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
Claims (4)
1. an exhaust pipe seal gasket sheet, comprise through hole (2) and mounting hole (4), pad is made up of the welding of upper and lower two panels sheet metal (3), it is characterized in that: be lined with one deck ceramic fiber (6) in the upper and lower two panels sheet metal (3) of pad.
