Abstract
The utility model discloses a novel round valve. The round valve comprises a ventilation pipeline and a blade arranged in the ventilation pipeline, wherein the blade is arranged on a rotary member; the rotary member is arranged on the pipe wall of the ventilation pipeline in a penetrating manner so as to enable the blade and the rotary member to rotate together; and a protective cover is arranged on the ventilation pipeline, is used for covering two ends of the two ends of the rotary member, and is a copper circular protective cover. According to the utility model, by arranging the protective cover at the two ends of the rotary member, the outside complex environment is isolated from the two ends of the rotary member to prevent the two ends of the rotary member from rust. Meanwhile, outside debris and dust are prevented from entering a gap between the rotary member and the ventilation pipeline. According to the scheme, the reliability and the safety of the novel round valve are ensured, and the practical service life of the novel round valve is prolonged.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of flexibly, the novel round valve of good reliability.
Background technique
At present, the blade in the round valve is connected by running shaft with ventilation duct, and rotating shaft terminal is exposed to the external world.External environment is complicated, causes that easily rotating shaft terminal gets rusty.Running shaft rotation underaction after getting rusty, when particularly needing blade rotary to arrive some specific angle, the running shaft that gets rusty will be difficult to the angle of blade rotary to appointment had a strong impact on reliability, the Security of whole blower fan.Secondly, rotating shaft terminal is exposed in the ambient air, allows easily some foreign material, dust enter in the gap of running shaft and ventilation duct, and running shaft is blocked, and affects the normal operation of running shaft.
The model utility content
For the deficiencies in the prior art, the utility model provides a kind of novel round valve of rational in infrastructure, good reliability.
For reaching this purpose, the utility model by following technical solution:
Novel round valve, comprise ventilation duct and be arranged at the interior blade of ventilation duct, described blade is arranged on the revolving part, this revolving part runs through to be arranged at makes described blade and described revolving part rotate together on the described ventilation duct tube wall, wherein, described ventilation duct is provided with protective housing with at least one end shield in the described revolving part two ends firmly.
Further, described revolving part two ends are equipped with described protective housing, and this protective housing is the copper protective housing.
Further, described protective housing is circular protective housing.
Further, also be provided with the controlling mechanism of control blade rotary angle between described ventilation duct and blade.
The utility model is by technique scheme, and its beneficial effect is: be arranged at the protective housing at revolving part two ends, extraneous complex environment and described revolving part two ends are isolated, prevent that the revolving part two ends from getting rusty.Simultaneously, preventing that external impurities, dust from entering in the gap of described revolving part and ventilation duct blocks this revolving part.Can guarantee reliability, the Security of novel round valve, the actual life of having improved novel round valve by such scheme.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is another structural representation of the utility model.
Fig. 3 is an again structural representation of the utility model.
Among the figure: 1, ventilation duct, 2, blade, 3, revolving part, 4, protective housing, 5, controlling mechanism.
Embodiment
Now by the drawings and specific embodiments the utility model is described in further detail:
Embodiment, as shown in Figure 1 to Figure 3, novel round valve, comprise ventilation duct 1 and be arranged at the interior blade 2 of ventilation duct, described blade is arranged on the revolving part 3, and this revolving part 3 runs through makes described blade 2 and described revolving part 3 rotate together on the tube wall that is arranged at described ventilation duct 1, wherein, described ventilation duct 1 is provided with protective housing 4 described revolving part 3 two ends is covered, and this protective housing 4 is the copper protective housing, and described protective housing 4 is circular protective housing.2 in described ventilation duct 1 and blade also are provided with the controlling mechanism 5 of control blade 2 angle of swing.
The utility model is by being arranged at the protective housing 4 at revolving part 3 two ends, with extraneous complex environment and the isolation of described revolving part 3 two ends, prevents that revolving part 3 two ends from getting rusty.Simultaneously, preventing that external impurities, dust from entering in the gap of described revolving part 3 and ventilation duct 1 blocks this revolving part 3.Can guarantee reliability, the Security of novel round valve, the actual life of having improved novel round valve by such scheme.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
