Background technique
Traditional impingement type hydraulic generator speed governing relies on closing gate size and water level difference of height to control substantially, complex operation, and in addition, hydraulic loss is large, and water resource waste is serious, and efficiency is low.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provides a kind of simple to operate, regulates accurately and the oil cylinder of water saving.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of oil cylinder, comprise the outer cylinder body and the inner cylinder body that by least one landing nipple, are connected, described inner cylinder body comprises cylinder barrel, front capping and rear seal-cover, a described outer cylinder body side corresponding with front capping is provided with the opening of taper, this open outer side is fixedly connected with jet pipe, described front capping is fixedly connected with coaxial conical head outward, and this conical head can pass from the opening of outer cylinder body and energy shutoff jet pipe; In described inner cylinder body, be provided with coaxial piston and piston rod, and the spring that is sleeved on piston rod outside, one end of piston rod passes from piston, and the other end of piston rod passes and is connected with conical head in capping in the past.
One end arranged outside that described piston rod is connected with piston has magnet ring, central axis place is provided with endoporus, on described rear seal-cover, be provided with displacement transducer, this displacement transducer one end is connected with the guide rod of built-in electric wire, the other end of this guide rod passes magnet ring and endoporus, and can in endoporus, move forward and backward.
Piston rod outside between described front capping and spring is set with balance set, between described spring and balance set, is provided with spring seat.
The present invention adopts after said structure, between above-mentioned outer cylinder body and inner cylinder body, be filled with press water, when needs reduce water speed, only need be to oil-filled pressurization in the cavity of inner cylinder body piston-rodless, piston moves forward promotion piston rod, the moving conical head of piston rod moving belt moves forward shutoff jet pipe, thereby reduces the flow velocity of water; When needs increase water speed, the release of draining the oil in the cavity of inner cylinder body piston-rodless, conical head, under the drive of spring, will slowly leave jet pipe, thereby increase water speed.Above-mentioned displacement transducer can accurately be monitored the shift value of piston rod, thereby regulates more accurately the flow velocity of water.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of oil cylinder of the present invention.
Wherein have: 1. outer cylinder body; 2. inner cylinder body; 3. landing nipple; 4. jet pipe; 5. front capping; 6. cylinder barrel; 7. rear seal-cover; 8. piston; 9. piston rod; 10. spring; 11. conical heads; 12. magnet rings; 13. displacement transducers; 14. guide rods; 15. endoporus; 16. balance sets.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation with concrete better embodiment.
As shown in Figure 1, a kind of oil cylinder, comprise the outer cylinder body 1 and the inner cylinder body 2 that by least one landing nipple 3, are connected, described inner cylinder body 2 comprises cylinder barrel 6, front capping 5 and rear seal-cover 7, described outer cylinder body 1 side corresponding with front capping 5 is provided with the opening of taper, this open outer side is fixedly connected with jet pipe 4, the outer coaxial conical head 11 that is fixedly connected with of described front capping 5, and this conical head 11 can pass from the opening of outer cylinder body 1 and energy shutoff jet pipe 4; In described inner cylinder body 2, be provided with coaxial piston 8 and piston rod 9, and the spring 10 that is sleeved on piston rod 9 outsides, the two ends of this spring 10 are provided with spring seat, one end of piston rod 9 passes from piston 8, the other end of piston rod 9 passes and is connected with conical head 11 in capping 5 in the past, is preferably and removably connects, according to the internal diameter size of jet pipe 4, change conical head 11 corresponding thereto, thereby make oil cylinder of the present invention can adapt to the jet pipe 4 of different inner diameters size.
One end arranged outside that described piston rod 9 is connected with piston 8 has magnet ring 12, central axis place is provided with endoporus 15, on described rear seal-cover 7, be provided with displacement transducer 13, these displacement transducer 13 one end are connected with the guide rod 14 of built-in electric wire, the other end of this guide rod 14 passes magnet ring 12 and endoporus 15, and can in endoporus 15, move forward and backward.
Above-mentioned displacement transducer 13 is monitored the shift value that moves forward and backward of piston rod 9 by the displacement situation of reaction magnetic ring 12, can regulate as required current size, sets corresponding shift value, can control exactly the speed of current.
Before described vicinity, on the spring seat of capping 5 and the piston rod 9 between front capping 5, be also set with balance set 16.This balance base 16 can prevent moving radially of piston rod 9 or shake, and makes this oil cylinder more stable work with reliable.
During use, between above-mentioned outer cylinder body 1 and inner cylinder body 2, be full of press water, when needs reduce water speed, flow velocity as required, set the shift value of piston rod 9, in the cavity of backward inner cylinder body 2 piston-rodless 9, oil-filled pressurization (does not mark oil filler pipe in figure, for prior art), piston 8 moves forward promotion piston rod 9, spring 10 compressions, and the movement of piston rod 9 moves forward drive conical head 11 and slow shutoff jet pipe 4, when piston rod 9 displacements reach setting value, by feedback signal, stop oil-filled pressurization, thereby reduce and keep the flow velocity of water; When needs increase water speed, flow velocity equally as required, set the shift value of piston rod 9, the release of draining the oil in the cavity of inner cylinder body 2 piston-rodless 9, spring 10 slowly resets, conical head 11 is under the drive of spring 10, to slowly leave jet pipe 4, when reaching setting shift value, by feedback signal, stop the release of draining the oil, thereby increase and keep water fast.Aforesaid operations is simple, and accurately, the utilization ratio of water is high, avoids the waste of water.
