Fig. 3 is the schematic diagram that spacer type double-action list piston hydraulic cylinder embodiment illustrated in fig. 2 is applied on sleeve kiln ash discharge drawer.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.First it should be noted that, the utility model is not limited to following embodiment, the spirit that those skilled in the art should embody from following mode of execution is to understand the utility model, and each technical term can do the most wide in range understanding based on Spirit Essence of the present utility model.Reference character identical in the accompanying drawings represents identical part.
As shown in Figure 2, the spacer type double-action list piston hydraulic cylinder of the utility model embodiment, comprise cylinder body 10, cylinder cap 21, piston 12, piston rod 1, guide sleeve 19, gland 18, spacer 3, cylinder cap 21 and guide sleeve 19 lay respectively at the two ends of cylinder body 10, cylinder cap 21 is fixedly connected with cylinder body 10, guide sleeve 19 is fixedly mounted in cylinder body 10 by gland 18, gland 18 contact guide sleeve 19, piston rod 1 is connected by Cock screw 15 with piston 12, piston 12 moves back and forth together with in cylinder body 10 inner chamber of piston rod 1 between cylinder cap 21 and guide sleeve 19 under the effect of hydraulic oil, cylinder body 10 is connected by Cock screw 20 with gland 18, spacer 3 is threaded with cylinder cap 21, spacer 3 is formed outside thread 3a and fluid to leak hole 5.Spacer 3 and cylinder this 21 after both are threaded, also give stationary positioned by Cock screw.Preferably, dust ring 2 is provided with in the front end of spacer 3.In the present embodiment, in the fluid of spacer 3 leaks hole 5, be provided with gear oil rubber 4.Cylinder cap 21 and piston 12 are being respectively equipped with axial seal 7 and radial seal such as O-ring seals 11 with piston rod 1 touching position.Cylinder cap 21 is also being provided with anti-extrusion ring 8 and support ring 9 with piston rod 1 touching position.Piston 12 is being provided with support ring 13 and radial seal with cylinder body 10 contacting point, such as O-ring seals 14.Guide sleeve 19 is being provided with radial seal such as O-ring seals 16 and anti-extrusion ring 17 with cylinder body 10 touching position.
