Abstract
The utility model discloses a pneumatic open movable reverser, particularly relates to a pneumatic open movable reverser small in size, low in noise and vibration and free of reflowing and splashing, and solves the technical problems that the existing pneumatic open reverser is large in size, has flow field disturbance, large in noise and poor in accuracy. The pneumatic open movable reverser comprises a nozzle and a divider hopper; the nozzle is fixed above the divider hopper; the divider hopper is driven through a pull bar. The pneumatic open movable reverser is simple in structure and never vibrates or rebounds during operating; the noise caused when a cylinder drives the pull bar to move is decreased effectively; accuracy of the whole reverser can be well guaranteed.
Description
Technical field
The utility model relates to the commutator in a kind of water flow standard apparatus, be specifically related to that a kind of volume is little, noise and vibration little, without the portable reverser assembly of the pneumatic open type of the phenomenon of turning one's coat, dabbling.
Background technology
Commutator is an important component part in flow standard device, is the necessary equipment of Static mass method, Static Volumetric Method water flow standard apparatus.It is arranged on the top of work measuring instrument (or container), by changing the direction of liquid flow, as the importing and exporting foundation of each calibrating fluid flow.In traditional commutator structure, having following weak point is:
1. physical dimension is larger, has flow field disturbance
Open type commutator all adopts swing type structure at present, is divided into two kinds of pendulum nozzle-type and pendulum guiding bucket types.
As shown in Figure 1, pendulum guiding bucket type is made up of nozzle 1, guiding hopper 2 and point bucket 3 three parts.Nozzle 1 and point bucket 3 are fixing, pull guiding hopper 2 to swing by cylinder or electromagnet, and current are imported to different measuring devices or container, realize commutation and the metering of current.
As shown in Figure 2, pendulum nozzle-type is made up of nozzle 1 and point bucket 3 two parts, and cylinder drives jet hole to swing, nozzle 1 below is a point bucket 3, swing by nozzle 1, by a point bucket 3, current are imported to different measuring devices or container, realize commutation and the metering of current.Swinging of nozzle, can produce the transient-upset to upstream flow field.
2. noise is large
Current pneumatic open type commutator all adopts without buffer structure cylinder, when cylinder stops, clashing into because the effect of inertial force produces, and can send very large sound.Meanwhile, also can cause the vibration of commutator body because clashing into, thereby affect its timing accuracy.
Utility model content
The technical problems to be solved in the utility model be current pneumatic open type commutator physical dimension large, have that flow field disturbance, noise are large, poor accuracy, provide and in a kind of work, do not produce vibration and bounce-back, noise is little, accuracy the is high portable commutator of pneumatic open type.
For achieving the above object, the utility model adopts following technical proposals: the portable commutator of a kind of pneumatic open type, comprise nozzle and point bucket, and nozzle is fixed on the top of point bucket, and a point bucket is driven by pull bar, and pull bar is driven by cylinder.
Described cylinder is double buffering cylinder.
Described point bucket adopts guide pillar guide sleeve structure.
Adopt the utility model after said structure, with the comparison of pendulum guiding bucket type structure, omitted guiding hopper, dwindled greatly the whole height of commutator, reduced and taken up space; With the comparison of pendulum nozzle-type, nozzle is fixed, and unconfined flow phenomenon, has increased reliability; In work, do not produce vibration and bounce-back, the noise having caused while effectively having reduced the motion of cylinder drive pull bar, can be good at ensureing the accuracy of package unit.
Brief description of the drawings
Fig. 1 is the pendulum guiding bucket type commutator structure schematic diagram of prior art.
Fig. 2 is the pendulum nozzle-type commutator structure schematic diagram of prior art.
Fig. 3 is the utility model commutator structure schematic diagram.
Embodiment
As shown in Figure 3, the utility model comprises nozzle 1 and point bucket 3, and nozzle 1 is fixed on the top of point bucket 3, and a point bucket 3 is driven by pull bar 4, and pull bar 4 is driven by cylinder 5.By the horizontal rectilinear motion of point bucket 3, in the time having current to pass through, cylinder 5 pulls point bucket 3 to realize the switching of water (flow) direction; With the comparison of pendulum guiding bucket type structure, omit guiding hopper, dwindle greatly the whole height of commutator, reduce and taken up space; With the comparison of pendulum nozzle-type, nozzle is fixed, and unconfined flow phenomenon, has increased reliability.
Described cylinder 5 is double buffering cylinder.At ingoing stream switching state not with while stopping, cylinder 5 slowly starts or stops, and at real commutating zone, 5 rapid movements of cylinder, ensure time requirement and the symmetry requirement of commutation, and do not produce at work vibration and bounce-back, effectively reduced the noise that causes when cylinder 5 drives pull bar 4 to move, can be good at ensureing the accuracy of package unit.
A described point bucket 3 adopts guide pillar guide sleeve structure, and a point bucket 3 moves and adopts guide pillar guide pin bushing form, and machining precision is high, flexibly mobile.
Below the course of work of the present utility model is summarized as follows:
As shown in Figure 3, when under the state of water device in water flowing, cylinder 5 pulls point bucket 3 to carry out horizontal linear and moves, and current are divided to water conservancy diversion, in this process, the situation that commutator dabbles can not occur; When cylinder 5 moves, can reduce cylinder in the produced simultaneously noise and the vibration that drive pull bar 4 to move, ensure that symmetry and the repeatability of commutator meets the requirements, thereby ensured the accuracy of whole water device.
