Abstract
The invention discloses a kind of trench valve core of the electromagnetic valve structure, on spool 2 on the part of 1 clearance fit of valve pocket, offer several drainage troughs 3,4 times of the area of passage of drainage trough 3 not less than 4 area of section of oil return runner in valve pocket 1.Dynamic response caused by the trench valve core of the electromagnetic valve structure that the present invention designs solves the problems, such as solenoid valve due to the crevice throttle between spool and valve pocket component is relatively low, the trench valve core of the electromagnetic valve structure of design is applied in solenoid valve significantly improve response speed when solenoid valve switches on and off, and improves solenoid valve dynamic response performance.
Description
Technical field
The invention belongs to Solenoid Valve Technologies, and in particular to a kind of trench valve core of the electromagnetic valve structure.
Background technique
Solenoid valve is a kind of electro-hydraulic converting element, is made of coil block and oil intake assembly.Wherein coil block is electrical
Element, oil intake assembly are Hydraulic Elements.Oil intake assembly is made of valve pocket component and spool, and solenoid valve passes through control coil component
Power supply generates electromagnetic force to control position of the spool in valve pocket component everywhere in oil intake assembly to reach switching oil intake assembly
The effect of oil circuit.Spool and valve pocket in oil intake assembly are cooperatively connected using interval.Hydraulic oil is in valve pocket group when electromagnetic valve work
Crevice throttle is generated in gap between part and spool, so that valve core movement is limited, causes solenoid valve dynamic response performance poor.
The invention proposes a kind of trench valve core of the electromagnetic valve structure, which can guarantee that spool is transported in valve pocket component
Ensure to pass through trench valve core structure increase spool two under the premise of the fit clearance between spool and valve pocket component is constant when dynamic
The area of passage at end prevents from generating crevice throttle influence valve core movement at spool, can effectively improve the dynamic response of solenoid valve
Characteristic.
Summary of the invention
The purpose of the present invention: to solve solenoid valve due to the crevice throttle that clearance fit generates between spool and valve pocket component
The poor problem of caused solenoid valve dynamic response performance.By designing trench spool, spool and valve pocket component is avoided to generate
Crevice throttle proposes a kind of trench valve core of the electromagnetic valve structure.
Technical solution of the present invention:
A kind of trench valve core of the electromagnetic valve structure, which is characterized in that on spool 2 and on the part of 1 clearance fit of valve pocket, open
Equipped with several drainage troughs 3, the area of passage of drainage trough 3 is not less than 4 times of 4 area of section of oil return runner in valve pocket 1.
The spool 2 uses 440C stainless steel material.
The cross-sectional area of the drainage trough 3 is rectangle.
The drainage trough 3 is two, and symmetrical on spool 2.
Advantages of the present invention:
The trench valve core of the electromagnetic valve structure that the present invention designs solves solenoid valve because of the seam between spool and valve pocket component
Gap throttling and caused by the relatively low problem of dynamic response, the trench valve core of the electromagnetic valve structure of design is applied to can in solenoid valve
The significant response speed improved when solenoid valve switches on and off, improves solenoid valve dynamic response performance.
Detailed description of the invention:
Fig. 1 is concrete structure schematic diagram of the invention.
Fig. 2 is valve core structure schematic diagram of the present invention.
Wherein, 1 is valve pocket, and 2 be spool, and 3 be drainage trough, and 4 be oil return runner.
Specific embodiment:
The invention will be described in further detail with reference to the accompanying drawing.
As shown in Figure 1, 2, in the embodiment of the present invention, spool 2 uses 440C stainless steel material, on spool 2 with 1 gap of valve pocket
On the part of cooperation, a drainage trough 3 is offered, cross-sectional area is rectangle, and the size of oil return runner 4 is diameter in the present embodiment
For the circle of 0.8mm, area is 0.5mm2, therefore, the rectangle of 3 selection of dimension 1mm*2mm of drainage trough, area is 2mm2。
When electromagnetic valve work coil block be powered when spool moved downward in valve pocket component, the steel ball in valve pocket component with
It is adjacent on the left of valve pocket, the control chamber Pa chamber and oil suction chamber Ps of solenoid valve are connected.The spool left end when valve core of the electromagnetic valve is moved to the left
Hydraulic oil between valve pocket component enters electromagnetic valve oil return chamber T chamber by the drainage trough on spool.Work as coil assemblies of solenoid valves
When power-off, spool moves right in valve pocket component, is adjacent on the right side of the steel ball in valve pocket component and valve pocket, the control chamber of solenoid valve
Pa chamber and oil back chamber T chamber are connected.When solenoid valve moves right, oil back chamber T chamber hydraulic oil enters valve by the drainage trough on spool
In core leftward space.It solves hydraulic oil in valve core of the electromagnetic valve movement to flow in the fit clearance between spool and valve pocket component
Dynamic and generation hydraulic damping, improves the dynamic response performance of solenoid valve.
