A pipeline of the valve body is internally provided with a valve plate device, the valve plate device is connected with a valve plate opening device, the valve plate opening device comprises a control cylinder, and the control cylinder is connected with an electromagnetic air valve through a pipeline, has the advantages that the transmission action is quick, the response is quick, the maintenance is simple, the working medium is clean and can not become bad, the working environmental suitability is good, the cost is low, and the like, and simultaneously, can realize the switching of remote control and on-site control.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of automatic ventilation valve that is used for ventilation duct.
Background technique
Be accompanied by the day by day strictness of country to air quality control, increasing large-scale dedusting, desulphurization plant are applied in power plant, cement plant etc., for air leak rate of air curtain, the adjustability requirement increase gradually of ventilation duct.At present on the mode of braking of pipe ventilated valve, have pneumatic, surge, all multimodes such as electronic.Electrical control validity height, actuation time is longer; Hydraulic control moment ratio of inertias is big, and action response is fast, but easily leaks, and is difficult for maintenance.
The model utility content
Technical problem to be solved in the utility model provides the automatic ventilation valve that a kind of volume is little, cost is low, actuation time is short, air leak rate of air curtain is little, applied widely.
For solving the problems of the technologies described above, the technical solution of the utility model is: the automatic ventilation valve, comprise valve body, the valve plate device is installed in the passage of described valve body, described valve plate device is connected with the valve plate opening device, described valve plate opening device comprises control cylinder, and described control cylinder is connected with electromagnetic gas valve by pipeline.
As optimized technical scheme, described valve plate device comprises the valve plate that is complementary with described valve channel shape, on the described valve plate valve shaft is installed, and the drive end of described valve shaft stretches out outside the described valve body, and described valve shaft is connected with described valve plate opening device.
As to improvement of the technical scheme, described valve body is provided with valve shaft grafting blind hole corresponding to the Partner of described valve shaft.
As to improvement of the technical scheme, described valve shaft comprises initiatively semiaxis and passive semiaxis, and described active semiaxis is fixedlyed connected with described valve plate respectively with passive semiaxis.
As to improvement of the technical scheme, be the wool felt sealing between described active semiaxis and the described valve body.
As to further improvement in the technical proposal, described control cylinder is the fixed cylinder of middle runners.
As to further improvement in the technical proposal, described ventilation valve is a rotary plate valve.
As to further improvement in the technical proposal, described ventilation valve is a push-pull valve.
As to further improvement in the technical proposal, described ventilation valve is the venetian blind valve.
Owing to adopted technique scheme, described valve plate opening device comprises control cylinder, and described control cylinder is connected with electromagnetic gas valve by pipeline; Control cylinder have actuation rapidly, reaction is fast, safeguard simple, working medium cleaning, do not have that medium is rotten, good, the low cost and other advantages of working environment adaptability, can realize that distant control and field control switch simultaneously.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is that the utility model embodiment A is to side view.
Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only some one exemplary embodiment of the present utility model has been described by the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
As depicted in figs. 1 and 2, the automatic ventilation valve, comprise valve body 2, the valve plate 1 that is complementary with described valve channel shape is installed in the passage of described valve body 2, on the described valve plate 1 valve shaft is installed, described valve shaft comprises initiatively semiaxis 3 and passive semiaxis 4, initiatively semiaxis 3 stretches out by being installed in rolling bearing units 7 on the valve body that valve body 2 is outer to be connected with the valve plate opening device, initiatively be the wool felt sealing between semiaxis 3 and the valve body 2, passive semiaxis 4 is corresponding to the valve shaft grafting blind hole 8 on the valve body, and fixed installation is sealing fully, has guaranteed the ventilation valve good seal.The opening device that is connected with active semiaxis 3 connects and comprises that control cylinder 5, control cylinder 5 are the fixed cylinder of middle runners, can long working need not lubricating maintenance.Control cylinder 5 is connected with active semiaxis 3 by valve arm 6, and control cylinder 5 also is connected with electromagnetic gas valve by pipeline, and ventilation valve can be opened for a long time or be closed, and flexible movements can realize distant control and field control switching simultaneously.Ventilation valve can have many specifications such as DN100-DN2000 for rotary plate valve, push-pull valve, venetian blind valve, adopts without the material manufacturing, is applicable to the requirement of different flue gas medium and operating mode.Required source of the gas adopts the clean compressed air of 0.3-1.0MPa, and working medium obtains easily, and the air after using is discharged in the atmosphere, and is pollution-free.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
