Abstract
The utility model discloses a pneumatic switch valve for powder, which comprises a valve body, a valve rod is rotatably arranged in the valve body, one end of the valve rod extends out of the valve body, a rotating power device is connected at the extending end of the valve rod, a semicircular funnel-shaped valve core is fixed on the valve rod in the valve body, a sealing clapboard is fixed in the valve body, a material feeding port is arranged on the sealing clapboard, and part of the arc surface of the semicircular funnel-shaped valve core extends into the material feeding port. When in work, an air supply system supplies power, and then a driving mechanism drives the semicircular funnel-shaped valve core to sway to the position of a limiting block in the valve body, so that a cylinder completes an action, and the semicircular funnel-shaped valve core completes a working cycle under the driving of the driving mechanism; and when the semicircular funnel-shaped valve core is opened, low-pressure air enters the pneumatic switch valve body through an air chute, thus enabling the powder to be in a fluidized state and slantingly flow to the next procedure for use.
Description
Technical field
The utility model relates to a kind of pneumatic on-off valve.
Background technique
Along with China's economy develops fast, living standards of the people constantly improve, and have driven developing rapidly of cement industry.Air conveyer flume is used also more and more widely as defeated grey facility, and the discharge port place of consideration air flume need increase a switch valve and be controlled.In the application system of reality, because the position deflection of pipeline, the deviation of mounting point, and the factors such as sealing characteristics of valve all need the end position of regulating valve switch, guarantee " zero leakage " and " full gate degree " of valve.
The model utility content
Technical problem to be solved in the utility model provides a kind of good airproof performance, long service life, is not subjected to the powder pneumatic on-off valve of the influence of ambient temperature.
For solving the problems of the technologies described above, the technical solution of the utility model is: the powder pneumatic on-off valve, comprise valve body, be rotatablely equipped with valve rod in the described valve body, one end of described valve rod stretches out described valve body, the external part of described valve rod is connected with rotational power plant, be installed with semicircle bucket shape spool on the described valve rod in the described valve body, described valve body internal fixation is equipped with seal diaphragm, described seal diaphragm is provided with the punishment in advance mouth, and the part arcuate surface of described semicircle bucket shape spool extend in the described punishment in advance mouth.
As a kind of improvement, described rotational power plant comprises the cylinder that is installed on the described valve body, and described cylinder is connected with transmission device, and described transmission device connects described valve rod.
As further improvement, described transmission device is a connecting rod.
As further improvement, described seal diaphragm comprises the sealing plate body, and described sealing plate body is provided with described punishment in advance mouth, and the edge of the described punishment in advance mouth of described sealing plate body is fixed with the sealing felt.
Owing to adopted technique scheme, the powder pneumatic on-off valve, comprise valve body, be rotatablely equipped with valve rod in the described valve body, an end of described valve rod stretches out described valve body, and the external part of described valve rod is connected with rotational power plant, be installed with semicircle bucket shape spool on the described valve rod in the described valve body, described valve body internal fixation is equipped with seal diaphragm, and described seal diaphragm is provided with the punishment in advance mouth, and the part arcuate surface of described semicircle bucket shape spool extend in the described punishment in advance mouth; During work, after air-channel system provided power, driving mechanism drove the semicircle bucket and be rocked to the limiting stopper place in valve body; Cylinder is finished an action, has finished a work cycle at the drive lower semi-circle bucket of driving mechanism; When pneumatic on-off valve semicircle bucket was opened, low-pressure air made material be fluidized state when entering in the jettron valve body by air flume, and outflow along inclined direction enters next process continuation use.
