Description
Technical field
It the utility model is related to a kind of electric-controlled hydraulic pressure-reducing valve.
Background technology
At present, the pressure-reducing valve that hydraulic system uses has level pressure, fixed poor and surely than three kinds to the control mode of pressure relief value.Work as liquid
Pressure system requirements pressure relief value may result in complexity by level pressure, fixed poor and when controlling in the way of determining outside ratio using above pressure-reducing valve
Decompression control system.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of electric-controlled hydraulic pressure-reducing valve, can be by appointing
What requires to be depressurized.
Technical scheme is used by the utility model solves its technical problem：A kind of designed electric-controlled hydraulic pressure-reducing valve
Including nut cap, magnetic conduction cylinder sleeve, cover clamp, armature, coil, gusset piece, spacer, spring, valve body, valve element and sheath, valve element by
Three sections of cylinders are formed, and middle part cylinder diameter is maximum and its is provided with groove axially symmetricly, and valve element rear portion is thin bar, the thin bar
Through spacer, valve body front portion is opened up into and out of oilhole, and valve body middle front part is provided with convex step, the convex step with the middle part of valve element
Spring is housed, valve body rear portion is bolted with gusset piece, and armature center is provided with through hole, armature and magnetic conduction cylinder sleeve between cylinder
Gap coordinates, and the outside cylinder front end of magnetic conduction cylinder sleeve is provided with step post, and the step post is adapted with the stepped hole of gusset piece, magnetic guiding jar
Set endoporus front end is provided with stepped hole, and the stepped hole is adapted with the step post on spacer, and coil is loaded on magnetic conduction cylinder sleeve external cylindrical surface
On, coil and sheath are between gusset piece and cover clamp, and magnetic conduction cylinder sleeve rear end and nut cap thread connection, nut cap front end is supported
On cover clamp.
Operation principle of the present utility model is：The dutycycle of control coil just controls the magnetic field intensity of coil, also just controls
Magnetic force of the coil to armature is made.Armature can be in the position of a balance in the presence of magnetic force and spring force.Change magnetic
Power will change the position of armature, so as to change the position of valve element.The change of spool position just makes between the enterprising oil outlet of valve body
Restriction effect be changed, so as to obtain the decompression power of needs.During actual use, pressure is set to pass on the oil circuit after decompression
Sensor.The ECU of hydraulic system passes through control according to the pressure requirements of setting, and the oil pressure size that pressure sensor detects
The dutycycle of coil processed, it is possible to the pressure relief value needed.
The beneficial effects of the utility model are：It can be depressurized by any requirement.
