One end of bar 4 is fixedly connected with piston 5, and the other end of piston rod 4 stretches out the outside of cylinder body 1, and cylinder head 2 is sheathed on piston rod 4
Outside is simultaneously fixedly connected with 1 one end of cylinder body, and cylinder bottom 3 is sealingly fastened in the other end of cylinder body 1.
The first oil inlet and outlet 6, heat dissipation cavity 7 are provided on cylinder head 2 and into oil outlet 8；Second is provided on cylinder bottom 3 into fuel-displaced
Mouth 9.Wherein the first oil inlet and outlet 6 is connected with heat dissipation cavity 7, and heat dissipation cavity 7 and the inner cavity of the cylinder body 1 of 5 side of piston pass through disengaging
Oilhole 8 is connected.The inner cavity of the cylinder body 1 of 5 side of piston into oil outlet 8, heat dissipation cavity 7 and the first oil inlet and outlet 6 by being formed
Channel be connected with extraneous pipeline, the inner cavity of the cylinder body 1 of 5 other side of piston passes through the second oil inlet and outlet 9 and external world's pipeline phase
Connection, by controlling the valve body on extraneous pipeline, that realizes hydraulic oil flows in or out 1 inner cavity of cylinder body, to push piston 5,
Realize the flexible of piston rod 4, in relation to hydraulic systems and operation principles such as the pipelines, valve body, fuel tank that are connected with hydraulic cylinder, by
In belonging to the prior art, not repeated them here.Increase heat dissipation cavity 7 in cylinder head 2, enters using from the first oil inlet and outlet 6
And the heat in piston rod 4, cylinder head 2, cylinder body 1 is cooled down and is taken away by the hydraulic oil gone out, and utilizes the power of oil cylinder itself
Circular treatment heat, and then the sealing in cylinder head 2 is protected not fail because of thermal accumlation.Heat dissipation cavity 7 can be around
The toroidal cavity structure of piston rod 4 increases endotherm area in circumferential direction, improves heat dissipation effect.In heat dissipation cavity 7 and cylinder body 1
Inner cavity connection be arranged into oil outlet 8, under the premise of ensureing that heat dissipation cavity 7 is connected to cylinder body 1, make the interior of heat dissipation cavity 7 and cylinder body 1
Chamber is relatively isolated, and the hydraulic oil reduced in heat dissipation cavity 7 is influenced by the hydraulic oil of the inner cavity of cylinder body 1, makes the hydraulic pressure in heat dissipation cavity 7
Oily main heat of the absorption from cylinder head 2, the heat at oil cylinder head 2 is taken away by hydraulic oil, to reach the heat dissipation of cylinder head 2
Remarkable result makes the sealing of cylinder head 2 obtain effective protection, is particularly useful on the hydraulic cylinder at the high temperature such as steam power plant, steel rolling mill,
It can be made to seal service life and improve 4 times, reduce and replace the frequency, reduce failure rate, to improve production security and safeguard peace
Quan Xing.
