Description
Technical field
The utility model relates to a kind of liquid ejector, particularly about a kind of servo-type injector.
Background technology
Along with improving constantly of people's living standard and cultural taste, music fountain begins to appear in the middle of our daily life, and the increasing city of having made colorful.As the water scenery form of tool expressive force, music fountain requires the gimmick of designer with wonderful workmanship excelling nature, by Protean fountain moulding, in conjunction with jewelly illumination, reflects the theme and the intension of music.A good music fountain, the variation of water shape are crucial, and injector then plays a part very important therein.
Music fountain adopts magnetic valve and frequency converter to control the start and stop of self at present, and realizes water column height, the variation of running or beating.But there is following deficiency in this structure: 1, Frequency Converter Control system cost height, it is big to take cabinet space, and disturbs speaker effect, and noise is arranged.2, magnetic valve has only the open and close two states usually, can only realize running or beating of water shape, can not realize the effect that water column just rises and falls; And magnetic valve has higher requirements to the cleanliness factor of water, contains particle media in the water and just can not be suitable for when many.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of injection servo device, and with realization spout adjustable size, and the water column height is adjustable.
For achieving the above object, the utility model is taked following technical scheme: a kind of injection servo device is characterized in that it comprises: a housing, and sidewall connects water inlet pipe; One stepper motor is installed in described housing bottom; One power transmission shaft is connected on the described motor, extend into portion in the housing; One sensor is installed on the described housing sidewall; One zero-bit bolt is installed on the described power transmission shaft, and is corresponding with described sensor; One by a stator and the valve that moving plate is formed, and stator is fixed on the interface of described housing and external jet pipe, and moving plate is fixed on the described power transmission shaft, and is corresponding with stator.
Described moving plate direction of rotation is vertical with the jet pipe water (flow) direction.
Described stator is fixed on the described jet pipe.
Described stator is fixed on the described housing.
Described stator is one to have the circular piece in hole, have on the described moving plate with described stator on the corresponding blade in hole.
Blade on hole on the described stator and the described moving plate respectively is uniform three.
Described sensor and stepper motor are linked control system outward.
The head distance of the end of described sensor and zero-bit bolt is less than 5mm.
When the axle center of presetting described sensor and zero-bit bolt was on the same straight line, the indicator lamp of sensor was bright, and valve is in closed condition.
Described stepper motor adopts backbone sealing ring to carry out movable sealing, and bucker is equipped with in its outside.
The utility model is owing to take above technical scheme, it has the following advantages: 1, in the utility model, take the form of moving plate, stator rotation combination to constitute valve, moving plate is easily opening and closing under the drive of motor, and the rotation of moving plate is subjected to the water flow pressure load effect smaller; And computer passes through the control motor and then the drive moving plate rotates, and comes the control valve openings of sizes, and promptly the flow size reaches stepless adjustable.2, the utility model replacement by the mode of frequency converter and solenoid control water shape, changed because can control the height of water flow jet in the past, therefore can satisfy due performance effect.3, in the utility model, adopt closed-loop control system, introduce flow sensor or code-disc, realize that by feedback signal the real-time of valve is regulated the precision height.4, the utility model can effectively reduce cost and maintenance cost, is adapted at using in the large-scale music fountain.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a valve stator schematic diagram of the present utility model;
Fig. 3 is a valve moving plate schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1, the utility model comprises: a housing 1, a stepper motor 2, a power transmission shaft 3, a sensor 4, a zero-bit bolt 5, by a stator 6 and the valve that moving plate 7 is formed.
Shown in Fig. 2,3, by the valve that stator 6 and moving plate 7 are formed, stator 6 is one to have the circular piece in hole, is generally uniform three; Have on the moving plate 7 with stator on the corresponding blade in hole.Stator 6 is arranged on the bore position that jet pipe 8 and housing 1 join, and stator 6 both can be fixed on the jet pipe 8, also can be fixed on the housing 1; Moving plate 7 is connected in power transmission shaft 3 tops of stepper motor 2, and is upper and lower corresponding with stator 6.Moving plate 7 direction of rotation are vertical with jet pipe 8 water (flow) directions, and when moving plate 7 rotations, when stagger in the hole on blade and the stator 6, the water in the housing can flow in the jet pipe by valve; When moving plate 7 rotation, blade is when hole on the stator 6 overlaps, and the water in the housing is blocked by valve, can not flow in the jet pipe.
In the foregoing description, the head distance of the end of setting sensor 4 and zero-bit bolt 5 is less than a certain numerical value, is generally less than 5mm preferablely, and this moment, the sensor sensing effect was best.
And when the axle center of presetting sensor 4 and zero-bit bolt 5 was on the same straight line, the indicator lamp of sensor 4 was bright, and be designated as the zero position of valve this moment, and valve is in closed condition.
In the foregoing description, stepper motor 2 adopts backbone sealing ring to carry out movable sealing, and bucker is equipped with in its outside.
In the time of the work of this injection servo device, sensor 4 feeds back the anglec of rotation of moving plate 7, thereby make the state of control system according to the preset program by-pass valve control, realize that water column is by not having to the various variations that have from low to high, if a plurality of injectors are united use, can realize multiple water shape effect on the whole.
The foregoing description only is used to illustrate the utility model; wherein the structure of each parts, connected mode etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement all should not got rid of outside protection domain of the present utility model.
