Abstract
The invention discloses a kind of low noise hydraulic intensifiers comprising pressurizing pack, liquid controlled reversing valve module, buffer-braking component.The both ends plunger shaft of booster low-pressure piston is equipped with through-flow slot, when piston is moved to side, when the through-flow slot of the side is covered by piston, fluid can only be flowed out by the sequence valve in the side one way sequence valve, therefore brake pressure is generated to the low pressure chamber of the side by the one way sequence valve of the side, on the one hand make piston generate braking to stop, the end cap of the side will not be met, into without generating noise, on the other hand the overflow valve being connected with other side low pressure chamber is triggered to open, to promote the spool of liquid controlled reversing valve module to move, flow direction change, to which through-flow slot and one way sequence valve of the high pressure oil through the side flow into the low pressure chamber of the side, piston is pushed to be moved to the other side, repeatedly.The present invention can not only realize automatic continuous supercharging, and generate shock between end cap when avoiding piston motion, greatly reduce noise.
Description
Technical field
The present invention relates to hydraulic intensifier technical field more particularly to it is a kind of can it is reliable, can automatically continuously be pressurized
Low noise hydraulic intensifier.
Background technology
Hydraulic intensifier is different using piston both ends active area and the identical principle of stress size, and hydraulic pressure is put
Low pressure can be increased to 200MPa or more by a kind of big ultrahigh-pressure hydraulic element, hydraulic intensifier.Hydraulic intensifier
Three kinds of single-acting one-stroke booster, single-action reciprocating booster and Double-action reciprocating formula booster can be divided into.Single-acting
For one-stroke booster due to can only be moved to a direction, by travel limit, output flow is limited, can not reach continuous increasing
Pressure, the scope of application are narrow.Single-action reciprocating booster may be implemented continuously to be pressurized, but can only one way supercharging, oil sources utilize
Rate only has half, output flow also limited.Two-way continuous supercharging may be implemented, no in Double-effect reciprocating hydraulic pressure booster
By travel limit, output flow is big, is ideal pressurizing elements.But traditional Double-action reciprocating formula that the country uses at present
Hydraulic intensifier is the continuous commutation by solenoid directional control valve, and control pressurized cylinder moves back and forth continuous output high pressure, and structure is multiple
Miscellaneous, volume and weight is huge, it has not been convenient to carry, be difficult to use in terms of inflammable and explosive occasion and portable mechanism.
Notification number is that the Chinese invention patent of CN101666339 discloses a kind of hydraulic intensifier, it is proposed that a kind of utilization
The scheme that Stroke Control reversal valve and main reversing valve control pressurized cylinder continuously move, the program is compared with domestic traditional utilization electromagnetism
The double-acting supercharger of reversal valve control commutation has innovation, but there is also following disadvantages：
1, since its return of stroke valve positioned using steel ball and chain is maintained at two positions, control pressurized cylinder is to different
Direction moves, complicated, difficulty of processing is big.And steel ball positioning is easy to fail, and when chain is pulled off, Stroke Control reversal valve
It will be in floating position, i.e. pressurized cylinder stop motion, therefore this control mode is unreliable；
2, it uses stroke control valve and main reversing valve Two-level Control, one side structure complex；On the other hand it is bound to
The reduction of charger boost frequency is caused, big flow output is not achieved.
3, after its piston moves to the end in one direction, piston can generate shock with the end cap of respective direction, continue
In high frequency motion, the continuous noise generated that hits of piston and end cap is very big, and produces adverse effect to service life.

Hydraulic fluid port T2 connections.
The operation principle and the course of work of the present invention is as follows：
When low-pressure piston 11 moves right, the reversing valve core 9 of liquid controlled reversing valve module is in P mouthfuls and A mouthfuls even at this time
Logical, the B mouthfuls of states being connected to T2 mouthfuls, A mouth of the high pressure oil through liquid controlled reversing valve module enters left low pressure chamber 4a, pushes low-pressure piston
11 move right, when low-pressure piston 11 move to right through-flow slot 7b it is not covered before, the fluid of right piston chamber 4b all passes through
Right through-flow slot 7b returns to the B mouths of liquid controlled reversing valve module, after low-pressure piston 11 covers right through-flow slot 7b, as shown in Fig. 2, right
The fluid of plunger shaft 4b can only return B mouthfuls by the sequence valve in right one way sequence valve 6b, therefore pass through 6b pairs of right one way sequence valve
Right low pressure chamber 4b generates brake pressure, on the one hand make low-pressure piston 11 generate braking stop will not encountering the right end cap into without
Noise is generated, left overflow valve 8a is on the other hand triggered and opens；After left overflow valve 8a is opened, P mouthfuls of fluid through left overflow valve 8a into
Enter the left control chamber 11a of reversing valve core 9, left control chamber 11a is also connected with the control port of right hydraulic control one-way valve 10b, by right liquid
It controls check valve 10b to open, the pressure oil of control chamber 11a left in this way pushes reversing valve core 9 to move right, the oil of right control chamber 11b
Liquid returns to T mouthfuls through right hydraulic control one-way valve 10b, and reversing valve core 9 moves to right position, P mouthfuls and B mouthful it is logical, A mouthfuls and T1 mouthfuls lead to；This
Sample, fluid enter right low pressure chamber 4b through the check valve in P mouthfuls, B mouthfuls, right one way sequence valve 6b and push low-pressure piston 11 to moving to left
It is dynamic.
In low-pressure piston 11 during being moved to the left, after low-pressure piston 11 opens the through-flow slot 7b in the right side, B mouthfuls of fluid
Check valve through right through-flow slot 7b and right one way sequence valve 6b enters right low pressure chamber 4b simultaneously, when low-pressure piston 11 moves downward
Left through-flow slot 7a is covered in, as shown in figure 3, the fluid of left piston chamber 4a can only pass through the sequence valve in left one way sequence valve 6a
A mouthfuls are returned, therefore brake pressure is generated to left low pressure chamber 4a by left one way sequence valve 6a, low-pressure piston 11 is on the one hand made to generate system
Dynamic stopping will not encounter left side end cap and be opened into right overflow valve 8b without generating noise, is on the other hand triggered；When right overflow valve
After 8b is opened, P mouthfuls of fluid enter the right control chamber 11b of reversing valve core 9 through right overflow valve 8b, right control chamber 11b also with left hydraulic control
The control port of check valve 10a is connected, and left hydraulic control one-way valve 10a is opened, and the pressure oil of control chamber 11b right in this way pushes commutation
Spool 9 is moved to the left, and the fluid of left control chamber 11a returns to T mouthfuls through left hydraulic control one-way valve 10a, and reversing valve core 9 moves to left position
Set, P mouthfuls and A mouthful are logical, B mouthfuls and T2 mouthfuls lead to；In this way, fluid enter through the check valve in P mouthfuls, A mouthfuls, left one way sequence valve 6a it is left low
Pressure chamber 4a pushes low-pressure piston 11 to move right.Repeatedly.
Therefore, booster can be with bilateral reciprocation and noiseless.
The foregoing is merely illustrative of the preferred embodiments of the present invention, the protection domain being not intended to limit the invention, it is all
