Description
Technical field
The utility model relates to a kind of motor with single-layer metal outlet pipe pad, belongs to outlet pipe pad technical field.
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 the continuous action that need bear high-temperature fuel gas, sealing operating mode very severe; The good and bad discharging and the performance that directly influences motor of outlet pipe pad, whether engine noise is met the demands all has direct influence simultaneously.
The outlet pipe pad adopts the asbestos composite board material more at present; Because asbestos composite board material stress relaxation rate is bigger; Effect lower seal weak effect, working life at high-temperature fuel gas are short, and asbestos belong to pollutant simultaneously, and carcinogenic composition is arranged; 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 the utility model provides a kind of motor with single-layer metal outlet pipe pad, and cost is low, long service life; Sealing reliability is strong; Be beneficial to environmental protection, can avoid occurring nonmetal outlet pipe pad stress relaxation, material and be prone to problems such as aging, overcome the above-mentioned deficiency of existing product.
The purpose of the utility model realizes through following technological scheme:
A kind of motor is with single-layer metal outlet pipe pad; Comprise shim body, the neutral position of said shim body is provided with exhaust port, and the edge is provided with the first sealing ripple around the exhaust port; The both sides of exhaust port are equipped with bolt hole, and the edge of said bolt hole is provided with the second sealing ripple.
The beneficial effect of the utility model is: be skillfully constructed, reasonable in design, cost is low, long service life, and sealing reliability is strong, is beneficial to environmental protection, can avoid occurring nonmetal outlet pipe pad stress relaxation, material and be prone to problems such as aging.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the described a kind of motor of the utility model embodiment with single-layer metal outlet pipe pad;
Fig. 2 is the sectional view of a kind of motor shown in Fig. 1 with single-layer metal outlet pipe pad A-A along the line;
Fig. 3 is the sectional view of a kind of motor shown in Fig. 1 with single-layer metal outlet pipe pad B-B along the line.
Among the figure:
1, shim body; 2, exhaust port; 3, bolt hole; 4, the first sealing ripple; 5, the second sealing ripple.
Embodiment
Shown in Fig. 1-3; The described motor of the utility model embodiment is with single-layer metal outlet pipe pad; Comprise shim body 1, the neutral position of said shim body 1 is provided with exhaust port 2, and the edge is provided with the first sealing ripple 4 around the exhaust port 4; The both sides of exhaust port 2 are equipped with bolt hole 3, and the edge of said bolt hole 3 is provided with the second sealing ripple 5.
Shim body 1 can select for use low carbon steel plate or stainless steel as bulk material, and thickness can require to select according to installation requirement and sealing load.The edge is provided with the first sealing ripple 4 around the exhaust port 2, and this is equivalent to around relief opening 2, set up together or multiple defence line, canned motor high-temperature fuel gas effectively; Cause under the bigger situation of installation final vacuum pipe flange facial disfigurement that the second sealing ripple 5 can be set in the edge of bolt hole 3, and it can remedy the distortion of outlet pipe flanged surface effectively, more helps the sealing of high-temperature fuel gas in that exhaust pipe structure is unreasonable.
The utility model is skillfully constructed, and is reasonable in design, has advantages such as good airproof performance, intensity height, long service life, solved outlet pipe sealing and environmental issue effectively.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the 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 the protection domain of the utility model.
