Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of opposite opened pneumatic gate valve, can be used for the technical fields such as vegetables and fruits machinery, also can be used for food, environmental protection and chemical industry Fabricating machinery.
Background technology
In palm fibre fruit fresh fruit string conveying storing process, because its fruit ear size is large, the gate that palpus open area is large realizes doses and controls, if open area is little, can produces knot arch, put up a bridge, cause discharging not smooth.
Existing gate comprises the flashboard be placed in valve flow channels, the supported on both sides of flashboard is on roller, during open-close sluice gate, flashboard slides under the traction of cylinder or hydraulic actuating cylinder on the roller of two groups, left and right, the outside of gate flow channels is provided with the space of shifting out for flashboard and the cylinder driving flashboard lifting or hydraulic actuating cylinder etc., cause the oad of gate excessive, flow channels at most only accounts for 30% of the gate gross area, in restricted clearance difficulty in installation and layout.When bulk materials is stuck between flashboard and doorframe, may cause two kinds of consequences: one flashboard is blocked by block material, gate cannot be completely closed; It two is that cylinder rod or the strength of gate disk are not enough, easily causes mechanical breakdown, reliability decrease after jam.Therefore, the reliability of traditional gate is not enough, under more harsh environment, as high temperature, dirty and have an impact environmental working condition under, can not operating needs be met.
Utility model content
The purpose of this utility model is, overcomes problems of the prior art, provides a kind of opposite opened pneumatic gate valve, and open area is large, and conveniently opening and closing is flexible.
For solving above technical matters, a kind of opposite opened pneumatic gate valve of the present utility model, comprise buffering hopper, described buffering hopper upper end is provided with inlet point, described buffering hopper lower end is provided with discharging opening, described buffering hopper lower end is provided with to be closed discharging opening and the arc-shaped door that can split, the rear and front end of described arc-shaped door is connected to swing arm, the upper end of described swing arm is separately fixed on the external end head of door-hinge, the rear and front end of described door-hinge is supported on the wallboard of described buffering hopper respectively, wherein one fan arc-shaped door swing arm in the middle part of be hinged with cylinder, the upper end thereof of described cylinder is on cylinder block, described cylinder block is fixedly connected on the top of described buffering hopper, same one end of described door-hinge is separately installed with synchronizer gear, and two synchronizer gears engage each other.
Relative to prior art, the utility model achieves following beneficial effect: when cylinder is without air feed, and gate is in closed condition under the effect of deadweight.When passing into pressurized air in cylinder, cylinder rod shrinks, and cylinder rod end hinge place produces the tractive force along cylinder-bore axis direction, and make arc-shaped door laterally and upwards swing, discharging opening is opened.When air feed reverse in cylinder, cylinder rod produces thrust, and arc-shaped door Fast synchronization is closed.Arc-shaped door is opening or closing in process, and synchronizer gear engages each other, and guarantees that the arc-shaped door symmetry of the left and right sides synchronously opens or closes, prevent side operating angle excessive cause jam or leak material.This device can realize the quick standard-sized sheet of major path, full cut-off easily, eliminates contingent knot doming effect; Oad is compact, and open area can reach more than 90% of body size, and carries buffering bucket, eliminates stockpile positive pressure, arc-shaped door is opened and closed light, flexible.
As preferred version of the present utility model, be also hinged with cylinder in the middle part of the swing arm of another fan arc-shaped door, described in two, cylinder symmetry is installed.The action force of two cylinder arrangement is more powerful, and on-off action accurately and reliably, is adapted to harsh working environment, meets high reliability request.
As preferred version of the present utility model, described door-hinge is near the line of centers of described buffering hopper fore-and-aft direction.Door-hinge is the closer to the line of centers of buffering hopper fore-and-aft direction, and the trend that two arc-shaped doors mutually close up under Gravitative Loads is larger.
As preferred version of the present utility model, described inlet point is circular or square.
As preferred version of the present utility model, described synchronizer gear and described cylinder are positioned at the same side of described buffering hopper.

Detailed description of the invention
As shown in Figures 1 to 6, opposite opened pneumatic gate valve of the present utility model comprises buffering hopper 1, and buffering hopper 1 upper end is provided with inlet point 1a, and inlet point 1a is circular or square.Buffering hopper 1 lower end is provided with discharging opening, buffering hopper 1 lower end is provided with to be closed discharging opening and the arc-shaped door 2 that can split, the rear and front end of arc-shaped door 2 is connected to swing arm 4, the upper end of swing arm 4 is separately fixed on the external end head of door-hinge 3, the rear and front end of door-hinge 3 is supported on the wallboard of buffering hopper 1 respectively, wherein one fan arc-shaped door 2 swing arm 4 in the middle part of be hinged with cylinder 5, the upper end thereof of cylinder 5 on cylinder block 6, cylinder block 6 be fixedly connected on buffering hopper 1 top; Same one end of door-hinge 3 is separately installed with synchronizer gear 7, and two synchronizer gears 7 engage each other.
When cylinder 5 is without air feed, gate is in closed condition under the effect of deadweight.When passing into pressurized air in cylinder 5, cylinder rod shrinks, and cylinder rod end hinge place produces the tractive force along cylinder-bore axis direction, and make arc-shaped door 2 laterally and upwards swing, discharging opening is opened.When air feed reverse in cylinder 5, cylinder rod produces thrust, and arc-shaped door 2 Fast synchronization is closed.Arc-shaped door 2 is opening or closing in process, and synchronizer gear 7 engages each other, and guarantees that arc-shaped door 2 symmetry of the left and right sides synchronously opens or closes, prevent side operating angle excessive cause jam or leak material, single cylinder can realize the driving to two arc-shaped doors 2.This device can realize the quick standard-sized sheet of major path, full cut-off easily, eliminates contingent knot doming effect; Oad is compact, and open area can reach more than 90% of body size, and carries buffering bucket, eliminates stockpile positive pressure, arc-shaped door 2 is opened and closed easily, flexible.
Also can be hinged with cylinder in the middle part of the swing arm 4 of another fan arc-shaped door 2, two cylinder symmetries are installed.The action force of two cylinder arrangement is more powerful, and on-off action accurately and reliably, is adapted to harsh working environment, meets high reliability request.
Door-hinge 3 is near the line of centers of buffering hopper 1 fore-and-aft direction.Door-hinge 3 is the closer to the line of centers of buffering hopper 1 fore-and-aft direction, and the trend that two arc-shaped doors 2 mutually close up under Gravitative Loads is larger.
Synchronizer gear 7 and cylinder can be positioned at the same side cushioning hopper 1, also can not be arranged in the same side.
The foregoing is only the better possible embodiments of the utility model, non-ly therefore limit to scope of patent protection of the present utility model.In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.The utility model can pass through without the technical characteristic described or adopt existing techniques in realizing, does not repeat them here.
