Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
Shown in Fig. 1 composition graphs 2,3, a kind of hydrodynamic(al) actuator, comprise piston cylinder 1, piston 2, piston rod 3 and Returnning spring 4 is provided with in described piston cylinder 1, described piston 2 is provided with containing groove 22, described Returnning spring 4 is located in containing groove 22, and such structure makes the Returnning spring in piston cylinder reliably install.The two ends of described piston cylinder 1 are provided with first-class through hole 11 and second through hole 12, described first-class through hole 11 is provided with the first pipeline 5 be connected with the water source that intakes, the first described pipeline 5 is provided with control valve 6, on the first described pipeline 5, the two ends of control valve 6 are parallel with second pipe 7, and described piston 2 is provided with the intercommunicating pore 21 being communicated with piston 2 two ends.Specifically, the aperture of the first pipeline 5 is greater than the aperture of intercommunicating pore 21.The invention has the beneficial effects as follows, adopt hydrodynamic(al) actuator to open or throttle down, not only environmental pollution is little but also energy consumption is low, and the water resources simultaneously adopted is again renewable resources, can greatly reduce costs.Intercommunicating pore is set on piston simultaneously, the two ends of piston cylinder are provided with first-class through hole and second through hole, intrasystem piston is made no matter to be in standard-sized sheet or closed positions, intercommunicating pore on second pipe and piston, water can be made to flow through second pipe, intercommunicating pore, drain opening continuously, form the state of long current.The hydrodynamic(al) actuator of this structure, security of operation, reliable.And the present invention also has the advantages such as structure is simple, easy to assembly, energy consumption is low, pollution-free.
Described second pipe 7 is provided with Rectifier plate 8, and described Rectifier plate 8 is provided with throttle orifice 81, and the aperture of described throttle orifice 81 is greater than the aperture of intercommunicating pore 21.Described Rectifier plate 8 comprises first throttle plate 82, second Rectifier plate 83 and the 3rd Rectifier plate 84,3rd Rectifier plate 84 is located between first throttle plate 82 and the second Rectifier plate 83, first throttle plate 82, second Rectifier plate 83 and the 3rd Rectifier plate 84 are respectively equipped with first segment discharge orifice 821, second section discharge orifice 831 and the 3rd throttle orifice 841, and the aperture of described first segment discharge orifice 821 and the aperture of second section discharge orifice 831 are all greater than the aperture of the 3rd throttle orifice 841.Described first throttle plate 82 and the second Rectifier plate 83 are by screw 9 Joint, and it is more reliable, more convenient that such structure makes product install.Throttle orifice and arranging of Rectifier plate can make in the water inflow system endlessly at water source.And arranging of throttle orifice slightly larger than intercommunicating pore, can ensure the water that in system, permanent current is logical sometimes, can not cause too many waste again.Certainly, second pipe can arrange controlling device, thus the rate-of flow that control enters in piston cylinder.
The two ends of described control valve 6 are equipped with stop valve 10.In particular, second pipe is connected in parallel on the path that two stop valves and control valve formed, and solenoid valve is forward and backward is all equipped with stop valve, works as solenoid valve failure, when need dismantle solenoid valve, makes to avoid intrasystem water source to leak by closing stop valve.Therefore the setting of stop valve, the trouble and worry well solve the maintenance of on-the-spot solenoid valve, changing.Specifically, described control valve 6 is two-position two-way solenoid valve.Certain control valve mainly controls the break-make of the first pipeline, can adopt other on-off valves to realize.Certainly one-way valve can be replaced by the stop valve of the first pipeline near first-class through hole.In the course of the work, stop valve is normally open, just closes during maintenance solenoid valve.When stop valve is opened, solenoid valve not charged (solenoid valve often leaves), water source enters piston upper chamber, piston driving piston rod compression reseting spring, and piston rod does down maneuver, now can throttle down.When stop valve is opened, solenoid valve is charged, and now action of reset spring is tried hard to recommend dynamic piston driving piston rod and done vertical motion, and valve is opened.No matter final controlling element is in standard-sized sheet or closed positions, intercommunicating pore on second pipe and piston, water can be made to flow through second pipe, intercommunicating pore, drain opening continuously, form the state of long current, avoid the operational failure of the final controlling element that the water source in system is corrupt, fouling brings.Certain the present invention is not only applicable in the keying of valve, and other devices that also can be used in other field are used as driving mechanism.
Every technician's notice: although the present invention describes according to above-mentioned embodiment, invention thought of the present invention is not limited in this invention, and the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
