Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
By Fig. 1 in conjunction with shown in Fig. 2,3, a kind of hydrodynamic(al) actuator, comprise piston cylinder 1, in described piston cylinder 1, be provided with piston 2, piston rod 3 and Returnning spring 4, described piston 2 is provided with containing groove 22, described Returnning spring 4 is located in containing groove 22, and such structure is reliably installed the Returnning spring in piston cylinder.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 being 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 that is 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 adopting is again renewable resources, can greatly reduce costs.Intercommunicating pore is set simultaneously on piston, the two ends of piston cylinder are provided with first-class through hole and second through hole, make no matter intrasystem piston is in standard-sized sheet or complete shut-down position, intercommunicating pore on second pipe and piston, can make water flow through continuously second pipe, intercommunicating pore, drain opening, form the state of long current.The hydrodynamic(al) actuator of this structure, security of operation, reliable.And the present invention also have simple in structure, easy to assembly, energy consumption is low, the advantage such as 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, the second Rectifier plate 83 and the 3rd Rectifier plate 84, the 3rd Rectifier plate 84 is located between first throttle plate 82 and the second Rectifier plate 83, on first throttle plate 82, the second Rectifier plate 83 and the 3rd Rectifier plate 84, be respectively equipped with first segment discharge orifice 821, second section discharge orifice 831 and the 3rd throttle orifice 841, the aperture of the aperture of described first segment discharge orifice 821 and second section discharge orifice 831 is 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 Joints, and it is more reliable, more convenient that such structure is installed product.The setting of throttle orifice and Rectifier plate can be so that in the water inflow system endlessly at water source.And arranging of throttle orifice can be slightly larger than intercommunicating pore, can guarantee in system the logical water of permanent current sometimes, can not cause too many waste again.Certainly, on second pipe, controlling device can be set, thereby control, enter the rate-of flow 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 of two stop valves and control valve formation, and the forward and backward stop valve that is all equipped with of solenoid valve, works as solenoid valve failure, while needing dismounting solenoid valve, by closing stop valve, makes to avoid intrasystem water source to leak.Therefore the setting of stop valve, the trouble and worry of well solved on-the-spot solenoid valve maintenance, changing.Specifically, described control valve 6 is two-position two-way solenoid valve.Certainly control valve is mainly the break-make of controlling the first pipeline, can adopt other on-off valves to realize.Certainly at the first pipeline, near the stop valve of first-class through hole, can be replaced by one-way valve.In the course of the work, stop valve is normally open, while just keeping in repair solenoid valve, closes.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, piston rod is done down maneuver, now can throttle down.When stop valve, open, solenoid valve is charged, and now action of reset spring is tried hard to recommend moving piston driving piston rod and done vertical motion, and valve is opened.No matter final controlling element is in standard-sized sheet or complete shut-down position, intercommunicating pore on second pipe and piston, can make water flow through continuously second pipe, intercommunicating pore, drain opening, form the state of long current, avoid the operational failure of the final controlling element that water source is corrupt, fouling brings in system.Certainly the present invention is not only applicable in the keying of valve, can be used on other devices of other field yet and be 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.
