Description
Technical field
A kind of Hydraulic Conirol Unit is the utility model is related to, more particularly to a kind of high-pressure high-flow controls without impact energy accumulation device
Component.
Background technology
In Quick-speed veneering hydraulic system of press, averagely using power 10KW, and fast lifting, Quick-pressing, moment are defeated
Go out power and reach 250KW, accumulator big flow discharges, and the impulsive force of moment is very big.
Accordingly, it is desirable to provide a kind of new technical scheme solves the above problems.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of high-pressure high-flow without impact energy accumulation device control assembly.
In order to solve the above technical problems, a kind of high-pressure high-flow of the present utility model is without impact energy accumulation device control assembly, it
Including control valve block, overflow valve, magnetic valve, electromagnetic relief valve, inserted valve, shuttle valve and two accumulators, two accumulators pass through
Large flange is fixed on control valve block, and the overflow valve, magnetic valve and electromagnetic relief valve are arranged on same control valve block, described
Overflow valve is connected with oil return pipe, and the oil return pipe is connected to fuel tank, and inserted valve is installed at the input and output hydraulic fluid port end of the accumulator,
Shuttle valve is installed on the inserted valve.
The accumulator is by check valve by fuel tank fuel feeding.
The beneficial effects of the utility model：The valve block of the accumulator control assembly, compact-sized, rigidity is big, flow output
It is that noise is small, connection safe clearance is especially big, No leakage long-time pressurize.

Embodiment
In order to deepen to understanding of the present utility model, the utility model is made below in conjunction with embodiment and accompanying drawing further
It is described in detail, the embodiment is only used for explaining the utility model, does not form the restriction to the scope of protection of the utility model.
As illustrated in fig. 1 and 2, for a kind of high-pressure high-flow of the present utility model without impact energy accumulation device control assembly, it includes control
Valve block 1, overflow valve 2, magnetic valve 4, electromagnetic relief valve 6, inserted valve 3, shuttle valve 5 and accumulator 7 processed, two accumulators 7 are by big
Flange 9 is fixed on control valve block 1, and to resist frequent impact vibrations, overflow valve 2, magnetic valve 4 and electromagnetic relief valve 6 are arranged on
On same control valve block 1, overflow valve 2 is connected with oil return pipe 8, and oil return pipe 8 is connected to fuel tank 11, the input and output oil of accumulator 7
Inserted valve 3 is installed at 10 ends of mouth, and shuttle valve 5 is installed on inserted valve 3.
The output of accumulator 7 is controlled using inserted valve 3, installs shuttle valve 5 on inserted valve 3 additional and steady control is realized by magnetic valve 4
System.
There is no pipeline connection between accumulator 7 and magnetic valve 4, accumulator 7 exports directly controlled by flow valve after export, valve
The rigidity of block is big, and flow output is that noise is small, and connection safe clearance is especially big, and overflow valve 2 also makes on the valve block simultaneously
It is compact-sized.
Cone valve structure, electromagnetic relief valve 6, the DBDS types direct-acting overflow valve 2 of inserted valve 3 can realize that No leakage is protected for a long time
Pressure.
Shown in Fig. 2, the course of work：
The first step：Accumulator 7, by the fuel feeding of fuel tank 11, passes through oil-filled, the accumulation of energy to accumulator 7 of check valve 12 by check valve 12
Device 7 stores energy, and pressure sensor 14 detects pressure, oil-filled stopping when reaching setting pressure, in holding state.
Second step：Magnetic valve 4 is powered, and the control chamber F of inserted valve 3 oil passes through the variable of inserted valve 3 by damping 13 oil returns
Restriction is slowly opened, the pressure oil of accumulator 7 steady quick release from small to large.By the size of the restriction of inserted valve 3 and
The size of damping 13 changes, and can be matched well with output system.Adjusting rod 15 limits maximum.
3rd step：The dead electricity of magnetic valve 4, the pressure oil of A, B chamber are compared by shuttle valve 5, it is ensured that inserted valve 3 is reliably closed.
It during emergency, can be associated with electrical control, close output, avoid other accidents.During generation accident, equipped with dead electricity
Automatic protection functions, output, automatic unloading pressure are closed during dead electricity.Releasing pressure automatically during shutdown, slowly release energy guarantee safety.
When environment temperature causes the energy storage pressure to raise when changing, voltage-limiting protection is carried out by overflow valve 2.
The utility model flow large impact is small, and flow output noise is small, No leakage long-time pressurize.Land structure, dismounting
It is convenient, meet ergonomics, installation capability is readily obtained guarantee.Make in industry of artificial boards Quick-speed veneering hydraulic system of press
With accumulator special mounting structure, high-power output can be realized, resists frequent impact, realizes high-pressure high-flow, it is reliable for a long time
Operation.
