Abstract
The utility model discloses a kind of double-layer seal stove motor, solve the problem that gas is revealed from bolt position, its drip irrigation device is a kind of double-layer seal stove motor, comprise housing and end cap, described end cap comprises the inner face with body contact, be bolted between described end cap and housing, described inner face is provided with the first sealing ring, described first sealing ring is positioned at outside bolt, described inner face is also provided with the second sealing ring, described second sealing ring is in inside bolt, and described bolt is between the first sealing ring and the second sealing ring.The utility model has the advantages that by being provided with the second sealing ring inside bolt, preventing gas from revealing from bolt position, the temperature of heat-treatment furnace can not be declined.
Description
Technical field
The utility model belongs to machine field, and in particular, it relates to double-layer seal stove motor.
Background technology
Stove motor is as the motive power of the various heat-treatment furnace Inner eycle blower fans of temperature less than 600 DEG C, existing stove motor, when motor uses, the High Temperature Gas cognition in heat-treatment furnace enters in motor, reveal from the contact position of housing and end cap, reduce heat treatment in-furnace temperature.
In prior art, application number be 201080012169.9 patent of invention be bolted end cap and housing, and be outside equipped with sealing ring at bolt, in actual use, gas can be revealed from the link position of bolt and end cap, sealing ring does not have the effect preventing from revealing, after the gas leakage of heat-treatment furnace, temperature in heat-treatment furnace can reduce, reduce the thermal effectiveness of heat-treatment furnace, when heat-treatment furnace carries out vacuum treatment simultaneously, air can enter in stove motor from the link position of bolt and end cap, affect the vacuum degree of stove motor and heat-treatment furnace.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of double-layer seal stove motor preventing gas from revealing from bolt.
For achieving the above object, the utility model provides following technical scheme: a kind of double-layer seal stove motor, comprise housing and end cap, described end cap comprises the inner face with body contact, is bolted between described end cap and housing, and described inner face is provided with the first sealing ring, described first sealing ring is positioned at outside bolt, described inner face is also provided with the second sealing ring, and described second sealing ring is in inside bolt, and described bolt is between the first sealing ring and the second sealing ring.
As preferably, described end cap also comprises outer face, described outer face is provided with the installing hole coordinated with bolt, and described installing hole is provided with sealing plate.
The utility model has following advantage compared to existing technology: by being provided with the second sealing ring inside bolt, the second sealing ring prevents gas from revealing from bolt, prevents the thermal effectiveness of heat-treatment furnace from reducing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged diagram in the portion of A shown in Fig. 1;
Fig. 3 is the enlarged diagram in the portion of B shown in Fig. 1.
In figure: 1, housing; 2, end cap; 21, inner face; 22, outer face; 3, the first sealing ring; 4, the second sealing ring; 5, sealing plate; 6, installing hole.
Embodiment
With reference to accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, a kind of double-layer seal stove motor, comprise housing 1 and end cap 2, end cap 2 comprises outer face 22 and inner face 21, be bolted between end cap 2 and housing 1, inner face 21 is provided with the first sealing ring 3, first sealing ring 3 and is positioned at outside bolt, inner face 21 is also provided with the second sealing ring 4, second sealing ring 4 is in inside bolt, bolt is between the first sealing ring 3 and the second sealing ring 4, and when mounted, the inner face 21 of end cap 2 abuts with the end face of housing 1; When two-side sealing stove motor uses, the second sealing ring 4 prevents the high temperature and high pressure gas produced in heat-treatment furnace from revealing from installing hole 6, thus prevents the temperature in heat-treatment furnace from can reduce, and the thermal effectiveness of heat-treatment furnace is not declined.
As shown in Figure 3, outer face 22 is provided with the installing hole 6 coordinated with bolt, installing hole 6 is provided with sealing plate 5, when mounted, bolt is fit into after in installing hole 6, and by being welded with sealing plate 5 on installing hole 6, sealing plate 5 prevents high-temperature gas from revealing from installing hole 6, play better sealing effectiveness, prevent high temperature and high pressure gas from revealing from installing hole 6.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
