Abstract

The utility model discloses a hydraulic cylinder with an energy accumulator, comprising a cylinder barrel with an oil port. The energy accumulator is fixed on the outer wall of the cylinder barrel by a bracket, and the oil port of the energy accumulator is communicated with the oil port of the cylinder barrel by a pipeline. The hydraulic cylinder has the following beneficial effects: the energy accumulator is fixed on the side wall of the cylinder barrel, a four-way valve block is utilized for communicating a plurality of pipelines with the oil port of the cylinder barrel, and an overflowing valve is embedded in the four-way valve block, so that more space is saved.

Description

The hydraulic jack of band accumulator
Technical field
The utility model relates to the hydraulic machinery technical field, relates in particular to a kind of hydraulic jack.
Background technique
Hydraulic jack is the engineering mechanical components of using always, is made of cylinder barrel and the piston rod and the piston that are positioned at cylinder barrel, when hydraulic jack is used for system's pressurize, generally needs to connect accumulator.
Way of the prior art is that a support is installed and fixing accumulator in extra being provided with, with pipeline oil cylinder and accumulator are linked together again, safety for the hydraulic jack system also needs to connect a relief valve in addition, and relief valve need utilize support and pipeline to install and be connected equally.
The installation consumable material of accumulator and relief valve is more in the prior art, and it is big to take up room, and Performance And Reliability is poor.
The model utility content
The utility model provides a kind of hydraulic jack with accumulator, and mounting point, the mounting type of accumulator are more reasonable, have saved space and material.
A kind of hydraulic jack with accumulator comprises the cylinder barrel that has hydraulic fluid port, and described accumulator is fixed on the cylinder barrel outer wall by carriage, and the hydraulic fluid port of accumulator and cylinder barrel hydraulic fluid port pass through pipeline connection.
Be fixed with the four-way valve piece at the cylinder barrel oil port, have four pipelines that are interconnected in the valve piece, wherein the first via is communicated with the cylinder barrel hydraulic fluid port, and the second the tunnel is communicated with the hydraulic fluid port of accumulator, Third Road is communicated with the pressure sensitive device, and the four the tunnel is communicated with the hydraulic oil oil circuit of hydraulic jack.
Be provided with the relief valve that directly communicates with described Third Road, relief valve can adopt the relief valve of direct-acting type.Described relief valve embeds in the four-way valve piece, has saved the space more.
Described cylinder barrel hydraulic fluid port, first via pipeline and the four road pipeline linearly distribute, and are convenient to reduce the oil circuit resistance, make the hydraulic oil between cylinder barrel hydraulic fluid port and the outside oil circuit flow more unobstructed.
The beneficial effects of the utility model are accumulator to be fixed on the sidewall of cylinder barrel, and utilize the four-way valve piece that many pipelines are communicated with the cylinder barrel hydraulic fluid port, and relief valve embeds and is installed in the four-way valve piece, has saved the space more.
Description of drawings
Fig. 1 is the partial sectional view of the hydraulic jack of the utility model band accumulator.
Embodiment
A kind of hydraulic jack with accumulator of the utility model comprises cylinder barrel 1, and the sidewall of cylinder barrel 1 one ends has hydraulic fluid port, is used for flowing to, flowing out of hydraulic oil.
Be installed with piston rod 6 in the cylinder barrel 1, the end that piston rod 6 stretches into cylinder barrel 1 inside is equipped with piston 7, and when hydraulic oil promoted piston 7, it is reciprocal that piston 7 can drive piston rod 6.
Accumulator 5 is for storing the container of hydraulic oil, and accumulator 5 is fixed on cylinder barrel 1 outer wall by carriage, and carriage can utilize various ways such as prefabricated clamp of the prior art.
Be fixed with valve piece 4 at cylinder barrel 1 oil port, have four pipelines that are interconnected in the valve piece 4, according to orientation among the figure:
The first via that opening is positioned at valve piece 4 belows is communicated with the hydraulic fluid port of cylinder barrel 1;
Opening is positioned at right-hand the second tunnel being communicated with the hydraulic fluid port of accumulator 5 of valve piece 4
The Third Road that opening is positioned at valve piece 4 lefts is communicated with pressure sensitive device (not shown);
Opening is positioned at valve piece 4 tops the four tunnel and is communicated with the external hydraulic oil oil circuit of hydraulic jack.
Wherein the cooperation place of the hydraulic fluid port of first via opening and cylinder barrel 1 is provided with seal ring 3, and valve piece 4 can be by being bolted to the hydraulic fluid port position of cylinder barrel 1.
As seen, be used for the Third Road that is communicated with the pressure sensitive device among the figure, be provided with relief valve 2, relief valve 2 is inlaid in the valve piece 4, has saved the space more.
The hydraulic fluid port of cylinder barrel 1, first via pipeline and the four road pipeline linearly distribute, and are convenient to reduce the oil circuit resistance, make in the cylinder barrel 1 with outside oil circuit between hydraulic oil mobile more unobstructed.
