Abstract

The invention discloses an oil cylinder which comprises an outer cylinder body and an inner cylinder body, wherein the outer cylinder body and the inner cylinder body are connected through at least one positioning connector. The inner cylinder body comprises a cylinder barrel, a front sealing cover and a rear sealing cover, the side, corresponding to the front sealing cover, of the outer cylinder body is provided with a conical opening, the outer side of the opening is fixedly connected with a spraying pipe, a conical head which is coaxial with the front sealing cover is fixedly connected to the outer side of the front sealing cover, and the conical head can penetrate out from the opening of the outer cylinder and plug the spraying pipe. A piston, a piston rod and a spring sleeved with the piston rod are arranged in the inner cylinder body, wherein the piston and the piston rod are coaxial, one end of the piston rod penetrates out from the piston, and the other end of the piston rod penetrates out from the front sealing cover and is connected with the conical head. After the structure is adopted, the conical head is driven by the piston rod to plug or depart from the spraying pipe slowly, and therefore the flow rate of water is reduced or increased.

Description

technical field [0001] The invention relates to a speed regulating device for an impact type hydraulic generator, in particular to an oil cylinder. Background technique [0002] The speed regulation of the traditional impulse hydro-generator basically depends on the closing size of the gate and the difference in water level for control, and the operation is cumbersome. In addition, the hydraulic loss is large, the waste of water resources is serious, and the efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil cylinder with simple operation, accurate adjustment and water saving in view of the above-mentioned deficiencies in the prior art. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] An oil cylinder includes an outer cylinder body and an inner cylinder body connected by at least one positi...
