Abstract
The utility model discloses a kind of plain film rotating vane seal valve, comprise the valve body with two cover apertures, carry out and cover the valve gap on valve body, and motor, also comprise cam and spring part; Motor is fixed on rotating shaft on valve body and stretches in valve body and bearing is fixed with it; Valve gap end is provided with trepanning and is enclosed within rotating shaft; Cam is fixed in rotating shaft and is fixedly connected with valve gap; Spring part is enclosed within one end and motor in rotating shaft and fixes the other end and connect with valve gap; Motor driving cam drives valve gap to move on valve body, covers in two cover apertures; Cam has guide-track groove, moves axially when cam rotates along rotating shaft, when valve gap is in that in the middle of two cover apertures, a cover apertures is rotated wherein, the spacing between valve gap and valve body from large to small.Spring part has one to the impacting force of valve body to valve gap, coordinates cam to be pressed in cover apertures by valve gap.When this product opening and closing for controlling breather line, effectively can prevent ventilation duct air leakage phenomena from occurring, avoiding the loss of main frame energy.
Description
Technical field
The utility model is a kind of control valve, is specially the valve opened and closed for controlling breather line.
Background technique
In the market, the electrically-controlled valve being used in central air-conditioner and the opening and closing of VMC control air conduit roughly has two kinds, a kind of is that the valve gap controlling pipeline folding does 90 degree of upsets on valve body, another kind is that the valve gap controlling pipeline folding does circular arc upset on valve body, the electrically-controlled valve of these two kinds of structures in actual applications, to the sealing effect of air conduit or unsatisfactory, there is the defect easily occurring air leakage phenomena, cause the loss of main frame energy in the valve gap controlling pipeline folding.
Model utility content
For problems of the prior art, it is strong that the purpose of this utility model is to provide a kind of sealing, for the seal valve that ventilation duct prevents air leakage phenomena from occurring.
The technological scheme adopted that solves the problem is:
A kind of plain film rotating vane seal valve, comprise the valve body at grade with two cover apertures, a shoe covers the valve gap on valve body, and motor, also comprises a cam and a spring part; Motor is fixed on valve body, and its rotating shaft is stretched in valve body and bearing is fixed with it; The end of valve gap is provided with trepanning and is enclosed within rotating shaft; Cam is fixed in rotating shaft and is fixedly connected with valve gap; Spring part is enclosed within one end and motor in rotating shaft and fixes, and the other end connects with valve gap; Motor driving cam drives valve gap to move between two cover apertures on valve body, covers in two cover apertures;
Cam has guide-track groove, and when driven by motor cam rotates, cam moves axially along rotating shaft, and when valve gap is in that in the middle of two cover apertures, a cover apertures is rotated wherein, from large to small, the cover apertures on valve body seals up the spacing between valve gap and valve body by valve gap.
Spring part has initial pretightening force, and the large I of pretightening force regulates as required.Spring part has one to the impacting force of valve body to valve gap, coordinates cam to be pressed in the cover apertures of valve body by valve gap, cover apertures is firmly sealed up.The utility model is mainly used in controlling breather line and opens and closes, and effectively can prevent ventilation duct air leakage phenomena from occurring, avoid the loss of main frame energy.
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model schematic perspective view;
Fig. 2 is the utility model structural representation.
Embodiment
As shown in Figure 1 and Figure 2, a kind of plain film rotating vane seal valve, comprises valve body 1, and a shoe covers valve gap 2, the motor 3 on valve body, also comprises a cam 5 and a spring part 4;
Valve body 1 has two cover apertures at same plane, and the utility model is mainly used in controlling breather line and opens and closes, and one of them cover apertures has a pipeline by mouth part 11 by Flange joint, is convenient to valve body 1 and is connected with admission line; Motor 3 is fixed on valve body 1, and its rotating shaft 31 is stretched in valve body 1 and bearing is fixed with it; The end of valve gap 2 is provided with trepanning and is enclosed within rotating shaft 31; Cam 5 is fixed in rotating shaft 31, is fixedly connected with valve gap 2; Spring part 4 is enclosed within one end and motor in rotating shaft 31 and fixes, and the other end connects with valve gap; Motor 3 driving cam 5 drives valve gap 2 to move between two cover apertures on valve body 1, covers in valve body 1 two cover apertures;
Cam 5 has guide-track groove, when rotating shaft 31 is with moving cam 5 to rotate, cam 5 moves axially along rotating shaft 31, when valve gap 2 is in that in the middle of two cover apertures, a cover apertures is rotated wherein, from large to small, the cover apertures on valve body 1 seals up spacing between valve gap 2 and valve body 1 by valve gap 2;
Valve gap 2 is plain film blade-rotation valve gap, and shape is fan-shaped or other shape of actual demand, and in the present embodiment, valve gap 2 preferentially adopts fan-shaped plain film rotating vane.
Spring part 4 has initial pretightening force, and the large I of pretightening force regulates as required.Spring part 4 pairs of valve gaps 2 have one to the impacting force of valve body 1, coordinate cam 5 to be pressed in the cover apertures of valve body 1 by valve gap 2, cover apertures are firmly sealed up.The utility model can effectively prevent ventilation duct air leakage phenomena from occurring, avoids the loss of main frame energy.
Above-mentioned mode of execution only as to explanation of the present utility model, limits the utility model never in any form.The technological scheme that the conversion of all employing equivalent technologies means obtains all belongs to the protection domain of this claim.
