Embodiment
Core of the present invention is to provide one stove of tumbling and shares hydraulic control system, the control that this system can realize multiple oil hydraulic cylinder by an oil feed line, and then control the operation of multiple stove of tumbling.
In order to make those skilled in the art understand technological scheme provided by the present invention better, below in conjunction with accompanying drawing and concrete mode of execution, hydraulic control system being shared to stove of tumbling provided by the present invention and is described in detail.
As shown in Figure 1, the structural representation of a kind of concrete mode of execution of hydraulic control system is shared for stove of tumbling provided by the present invention.As shown in the figure, be provided with multiple oil hydraulic cylinder 1 in this programme, multiple oil hydraulic cylinder 1 can control multiple stove of tumbling, and carries out the operation be elevated.
Device provided by the present invention has selector valve 2, hydraulic oil in same oil feed line can be supplied to different oil hydraulic cylinders 1 by selector valve 2, and selector valve 2, by switching different Placements, changes the flow direction of hydraulic oil, supply needs the oil hydraulic cylinder 1 of corresponding operating respectively, drives oil hydraulic cylinder 1 to rise.Particularly, the selector valve 2 in present embodiment is solenoid directional control valve, conveniently realizes Automated condtrol, can complete instruction without the need to manually-operable, reach the object simplified the operation.
Loop between oil hydraulic cylinder 1 with selector valve 2 is communicated with the first return line 4, the other end of the first return line 4 is communicated in fuel tank, forming one makes the hydraulic oil in oil hydraulic cylinder 1 flow into loop in fuel tank, first return line 4 is also provided with choke apparatus, by the break-make of oil circuit between choke apparatus hydraulic control cylinder 1 and fuel tank.Particularly, this choke apparatus is ball valve 5, and ball valve 5 controls the opening and closing of the first return line 4 by artificial operation, when ball valve 5 path, hydraulic oil is injected in fuel tank from oil hydraulic cylinder 1, and oil hydraulic cylinder 1 declines gradually, the rate of descent of the openings of sizes hydraulic control cylinder 1 of ball valve 5.Loop between selector valve 2 and fuel tank is also provided with ball valve 5, when oil hydraulic cylinder 1 is static do not work time, hydraulic oil can by open ball valve 5 be directly injected in fuel tank.
Between the oil outlet and fuel tank of oil pump 3, relief valve 6 is set; relief valve 6, along path between oil pump 3 to fuel tank, avoids oil pump 3 because oil pressure is excessive and causes damage, when oil pressure exceedes certain value; hydraulic oil is fed directly in fuel tank by relief valve 6, hydraulic pipe line is played to the effect of protection.
