Abstract
The utility model discloses a kind of rotary air valve, this air valve comprises rotary cylinder, valve body, rotating shaft and valve block, described valve body two ends are connected with gas channels respectively, and the diameter center that described rotating shaft runs through valve body is vertical with airflow direction, described rotary cylinder and rotating shaft synchronized links; Described valve block to be arranged in valve body and to be fixed in rotating shaft, and the external diameter of valve block is identical with the internal diameter of valve body.The utility model solves gas circuit can not the phenomenon of frequent quick on-off.The rotation of valve block realizes the break-make of gas circuit, volume and the less valve block of thickness size, swing inertia is little, the large inertia that the weight and volume not having ball valve larger brings, and diametric(al) contacts few with the internal diameter of valve body, frictional force is little, there is no the contact of the whole sphere of ball valve and the large frictional force produced, adopt light-duty blade type rotary cylinder to be driving force, volume is little, install simple and easy, so this mechanical flexibility, to be swift in response, improve manufacturing efficiency; Low inertia and less friction, reduce manufacturing cost and use cost.
Description
Technical field
The utility model relates to a kind of gas circuit control equipment, specifically rotary air valve.
Background technique
At home and abroad in packaging facilities and accumulator equipment, a lot of mechanism using negative-pressure adsorption object or large discharge air quantity to carry out absorbent bodies, this kind of mechanism requires whether the break-make controlling gas circuit is run to realize adsorption function usually.Existing equipment manually increases automaticity for reducing, being become by valve design can with the pneumatic or electronic ball valve performing rotation, but ball valve needs to fit to contact with valve body inner bore just can realize closing, and the swing inertia of the frictional force that sphere is larger and ball valve own wt makes existing mechanism cannot be applied in the occasion of frequent quick on-off; The Pneumatic butterfly valve that Ye You producer releases, structure adopts rack-shaped oscillating cylinder, and action runs rapid not, and manufacturing efficiency is low.
Model utility content
Model utility object: the utility model object there are provided a kind of rotary air valve making the frequent quick on-off of gas circuit.
For achieving the above object, the technical solution of the utility model is a kind of rotary air valve, comprise rotary cylinder, valve body, rotating shaft and valve block, described valve body two ends are connected with gas channels respectively, the diameter center that described rotating shaft runs through valve body is vertical with airflow direction, described rotary cylinder and rotating shaft synchronized links; Described valve block to be arranged in valve body and to be fixed in rotating shaft, and the external diameter of valve block is identical with the internal diameter of valve body.
Described rotary cylinder is blade type rotary cylinder.
Described rotary cylinder is fixed on valve body by fixed plate.
Also be provided with limiting stopper between described fixed plate and valve body, fixing board card is on limiting stopper.
Beneficial effect: the utility model solves gas circuit can not the phenomenon of frequent quick on-off.The rotation of valve block realizes the break-make of gas circuit, volume and the less valve block of thickness size, swing inertia is little, the large inertia that the weight and volume not having ball valve larger brings, and diametric(al) contacts few with the internal diameter of valve body, frictional force is little, there is no the contact of the whole sphere of ball valve and the large frictional force produced, adopt light-duty blade type rotary cylinder to be driving force, volume is little, install simple and easy, so this mechanical flexibility, to be swift in response, improve manufacturing efficiency; Low inertia and less friction, reduce manufacturing cost and use cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below according to specific embodiment, set forth the utility model further.
As shown in Figure 1, a kind of rotary air valve, comprise rotary cylinder 1, valve body 2, rotating shaft 3, valve block 4, fixed plate 5 and limiting stopper 6, valve body 2 two ends are connected with gas channels respectively, the diameter center that rotating shaft 3 runs through valve body 2 is vertical with airflow direction, rotary cylinder 1 and rotating shaft 3 synchronized links; Valve block 4 to be arranged in valve body 2 and to be fixed in rotating shaft 3, and the external diameter of valve block 4 is identical with the internal diameter of valve body 2, and limiting stopper 6 is fixed on valve body 2, and fixed plate 5 is installed on limiting stopper 6, and rotary cylinder 1 is fixed on fixed plate 5.Wherein rotary cylinder is blade type rotary cylinder.
During rotary cylinder 1 half-twist, the plane of valve block 4 and the axes normal of valve body 2, gas circuit is closed; Rotary cylinder 1 rotates again (up time direction or inverse time direction) 90 ° time the plane of the valve block 4 and axis being parallel of valve body 2, gas circuit is opened.Rotary cylinder 1 volume is little, can realize the rotation of upper frequency to realize the quick rotation of valve block 4, and reach the frequent quick on-off of gas circuit.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
