Abstract
The invention relates to a hydraulic cylinder with a sequence valve, which has the advantage that a one-way electromagnetic valve is used for controlling the hydraulic cylinder to finish reciprocating motion, thereby saving energy sources. An inductive drain valve of a water tank, which is manufactured by the invention enables the water tank to automatically drain and has low energy consumption.
Description
Technical field
The present invention relates to a kind of oil hydraulic cylinder, particularly a kind of piston-type hydraulic cylinder with sequence valve.
Background technique
Piston-type hydraulic cylinder generally is that the shell with oil hydraulic cylinder is fixed on the basic object, by input or discharge Medium Oil, makes the piston movement of oil hydraulic cylinder and drives operation mechanism's motion.Prior art will make hydraulic cylinder piston reciprocating, generally is to adopt the input and output of selector valve control oil hydraulic cylinder to realize.
Summary of the invention
Oil hydraulic cylinder of the present invention by adopting one with the piston of sequence valve, can realize doing with for export switch control of an one-way valve hydraulic cylinder piston purpose of fast reciprocating motion.
For solving above technical problem, the technical solution used in the present invention is: a kind of oil hydraulic cylinder with sequence valve, this oil hydraulic cylinder has cylinder body, the cylinder body two ends set out respectively the mouth of a river and water intake, the piston that is complementary with cylinder body is arranged in the cylinder body, and piston links to each other with piston rod, it is characterized in that: described piston is comprised of valve base and sequence valve, piston one side is provided with equalizing orifice, and the rubber gasket corresponding with the valve position is housed in cylinder body.
When water intake comes water, when water outlet was closed, because the effect of equalizing orifice, piston up and down two ends pressure equated, makes it be subject to downward active force because piston upper surface is long-pending greater than the following table area, and piston is positioned at the cylinder barrel cylinder body bottom.Sequence valve and valve base are closed, and mechanism is in original state.
When water outlet was opened, end pressure reduced rapidly on the piston, piston under the promotion of upward pressure, on move to the rubber seal pad position, at this moment sequence valve is closed by rubber gasket.
Under the effect of this pressure, the piston driving valve base moves to the rubber seal pad position on continuing.At this moment, sequence valve and valve base are opened.
When water outlet was closed again, piston upper end pressure increased sharply, and is subject to downward pressure-acting, and the piston driving valve base begins to move down.At this moment, sequence valve separates with rubber pad, and sequence valve is opened, and the current of piston cavity of resorption enter rapidly epicoele through the center hole of valve, and piston is pushed out.(
When piston together is displaced downwardly to the cylinder barrel cylinder body bottom the time together with valve base, sequence valve, sequence valve can not be moved by the restriction of cylinder body, and the piston driving valve base continues to move down.Sequence valve is closed again, is in original state, and circulation finishes.

Embodiment
As shown in Figure 1, the oil hydraulic cylinder that the present invention announces, set out respectively the mouth of a river 6, water intake 12, shunting disk 7 on the cylinder body 2, the piston 4 that is complementary with cylinder body is arranged in the cylinder body 2, piston 4 links to each other with piston rod 1, piston 4 is comprised of valve base 11, sequence valve 10, jump ring 8, seal ring 3, and piston 4 one sides are provided with equalizing orifice 9, and the rubber gasket 5 corresponding with sequence valve 10 positions is housed in cylinder body 2.
When water intake 12 comes water, when water outlet 6 is closed because the effect of equalizing orifice 9, piston 4 about two ends pressure equal, because of piston 4 top surface area greater than the following table area, make it be subject to downward active force, piston 4 is positioned at cylinder barrel cylinder body 2 bottom.Sequence valve 10 is closed with valve base 11, and mechanism is in original state.(seeing Fig. 2)
When water outlet 6 was opened, end pressure reduced rapidly on the piston 4, piston 4 under the promotion of upward pressure, on move to rubber gasket 5 positions, at this moment sequence valve 10 is closed by rubber gasket 5.(seeing Fig. 3)
Under the effect of pressure, piston 4 drives in valve base 11 continuation and moves to rubber gasket 5 positions.At this moment, sequence valve 10 is opened with valve base 11.(seeing Fig. 4)
When water outlet 6 was closed again, piston 4 upper end pressure increased sharply, and are subject to downward pressure-acting, and piston 4 drives valve base 11 to begin to move down.At this moment, sequence valve 10 separates with rubber pad 5, and sequence valve 10 is opened, and the current of piston 4 cavity of resorptions enter rapidly epicoele through the center hole of valve 10, and piston 4 is pushed out.(seeing Fig. 5)
When piston 4 together is displaced downwardly to cylinder barrel cylinder body 2 bottom the time (seeing Fig. 6) together with valve base 5, sequence valve 10, sequence valve 10 can not be moved by the restriction of cylinder body 2, and piston 4 drives valve bases 11 and continues to move down.Sequence valve 10 is closed again, is in initial (seeing Fig. 2) state, end-of-job.
