Abstract
The utility model relates to an all-metal exhaust pipe gasket for an engine, which comprises a gasket body, wherein the gasket body comprises a plurality of layers of stainless steel metal plates which are mutually welded, an exhaust hole is arranged in the middle position of the gasket body, sealing ripples which are mutually matched are arranged in the position of the exhaust hole of all the layers of the stainless steel metal plates, and bolt holes are arranged on two sides of the exhaust hole. The all-metal exhaust pipe gasket for the engine has the benefits of being capable of improving reliability and durability of sealing, further compensating for deformation defect on the surface of a flange of an exhaust pipe to the maximum extent and being conductive to environmental protection.
Description
Technical field
The utility model relates to a kind of motor full-metallic outlet pipe pad.
Background technique
As everyone knows, the outlet pipe pad is to be used for the high-temperature fuel gas that canned motor produces, its operating temperature is generally about 500 ℃, and need bear the continuous action of high-temperature fuel gas, the sealing operating mode is abominable, the good and bad discharging and the performance that directly influences motor of outlet pipe pad, simultaneously whether engine noise is met the demands and all have a direct impact, raising along with engine power, heat load increases, the thermal distortion of outlet pipe increases, and this just has higher requirement to the sealing reliability and the adaptability of outlet pipe.
Domestic outlet pipe pad mostly is the asbestos composite board material at present, adopt metal guard ring edge structure at the exhaust port place, because asbestos composite board material stress relaxation rate is bigger, rebound elasticity is little, therefore, this structure pad durability, heat resistance are relatively poor, to deformation-compensated ability, easily produce and leak, asbestos belong to pollutant simultaneously, carcinogenic composition is arranged, and many countries ban use of, so asbestos composite board material outlet pipe pad can not satisfy usage requirement.
The model utility content
The purpose of this utility model provides a kind of motor with full-metallic outlet pipe pad, seals reliably, and long service life is beneficial to environmental protection, and distortion has higher compensation ability to outlet pipe, to overcome the above-mentioned deficiency of existing product.
The purpose of this utility model is achieved through the following technical solutions:
A kind of motor full-metallic outlet pipe pad, comprise shim body, described shim body comprises the stainless steel metal plate that several layers is welded to each other, the neutral position of described shim body is provided with exhaust port, and described each layer stainless steel metal plate is equipped with the sealing ripple that cooperatively interacts at described exhaust port place; The both sides of described exhaust port are equipped with bolt hole.
The beneficial effects of the utility model are: are skillfully constructed, and reasonable in design, can improve sealing reliability, durability, and can compensate the defective of outlet pipe flanged surface distortion to the full extent, effectively solve outlet pipe sealing and environmental issue, and be beneficial to environmental protection, long service life.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described a kind of motor of the utility model embodiment with full-metallic outlet pipe pad;
Fig. 2 is the sectional view of the motor shown in Fig. 1 with full-metallic outlet pipe pad A-A along the line.
Among the figure:
1, shim body; 2, exhaust port; 3, bolt hole; 4, sealing ripple.
Embodiment
Shown in Fig. 1-2, the described motor of the utility model embodiment full-metallic outlet pipe pad, comprise shim body 1, described shim body 1 comprises the stainless steel metal plate that several layers is welded to each other, the neutral position of shim body 1 is provided with exhaust port 2, described each layer stainless steel metal plate is equipped with the sealing ripple 4 that cooperatively interacts at exhaust port 2 places, and the both sides of exhaust port 2 are equipped with bolt hole 3.
Shim body 1 is in compression process, and the sealing ripple 4 of each layer stainless steel metal plate all can produce certain elasticity, can compensate the distortion of outlet pipe flanged surface to the full extent.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but on its shape or structure, do any variation; every have identical with a application or akin technological scheme, all belongs to protection domain of the present utility model.
