Description
Technical field
The present invention relates to electromagnet, in particular to the electromagnet of feedback output, belong to magnet control device technology neck
Domain.
Background technique
Common electromagnet is powered by coil, and armature is attracted, and push rod band movable valve plug generates movement, then relies on when power is off
The pressure of spring resets armature and spool, to control the on-off deflecting of oil circuit.Current electromagnet is fed back without output
Information after the movement of function, i.e. valve rod can not be fed back in control system, so the information that whether medium flows in valve can not lead to
Electromagnet feedback is crossed, in certain occasions, such as in the place of security against fire, combustible and explosive area, it is dynamic that controller needs to obtain valve rod
The feedback information of work, simply using current electromagnet cannot achieve, and need using special hydraulic valve, this kind of hydraulic
The feedback device of valve is mounted on valve body, indivisible between valve body, and expensive, and if this hydraulic valve substitution
Whole substitution is needed if current common valve, not only capital consumption is big, it is also necessary to biggish project amount, in replacement process also
It needs system integrally to shut down, and much needs occasion not this requirement in pervious design of feedback signal at present,
What is used in initial design installation is all common valve, and this requirement is the fining requirement of upgrading and management with control
It generates, so how to realize one insoluble problem of feedback signal of valve rod movement on common valve.
Summary of the invention
It is an object of the invention to overcome the problems, such as in current common valve using cannot achieve signal control signal feed back,
A kind of switch electromagnet with feedback output is provided.
To achieve the purpose of the present invention, using following technical solutions: a kind of switch electromagnet with feedback output, packet
Switch electromagnet is included, attachment base A is fixedly connected on switch electromagnet, through-hole is in axial direction offered on attachment base A, even
The axial direction of push rod of axial direction and switch electromagnet of joint chair A is identical, and the through-hole is by the different hole A of three diameters, hole B, hole C
Composition, hole A is close to switch electromagnet and diameter maximum, and hole C far from switch electromagnet and diameter minimum, stretch by switch electromagnet front end
Enter in the A of hole and be fixedly connected with attachment base A, hole B is installed on the side wall of attachment base A by mounting hole between hole A and hole C
There is high pressure resistant sensor, high pressure resistant approach switch sensor is radial along attachment base A, in the high pressure resistant approach switch sensor
End is communicated with hole B, and in hole, the two sides of C offer the attachment base A oil-through-hole being connected to hole B, and the front end of attachment base A is provided with company
Joint chair B, attachment base B between valve seat for being connected, and the rear end of attachment base B offers spliced eye, and the front end of the A of attachment base is
The front end of multi-diameter shaft, attachment base A is inserted in spliced eye, has one section between the front end of attachment base A and the bottom of spliced eye
The periphery in youngster gap, attachment base B has annular protrusion, and inner screw sheath is threaded through the front of attachment base B peripheral annular protrusion, connects
One section of the multi-diameter shaft of seat A is upper to be connected with the screw thread matched with inner screw sheath, attachment base A and attachment base B by inner screw sheath
It is connected together, the hole D with through-hole C face is offered on attachment base B, hole D is equal with the diameter of hole C, the two of hole D on attachment base B
Side also offers attachment base B oil-through-hole, and connecting rod is fixedly connected on the push rod of electromagnet, and the front of the connecting rod is
The elongate rod matched with hole C and hole D, rear portion are the thick bar matched with hole B, and toroidal inductive signal is machined in thick bar
Slot, the length of the toroidal inductive signal slot is more than or equal to the diameter of the mounting hole of high pressure resistant approach switch sensor, described
The section of elongate rod be square that quadrangle is arc, square is the inscribed square of hole C, and the arc of quadrangle is located at and hole
On the C concentric same circumference, the difference of the radius of the radius and quadrangle arc of hole C is 0.01-0.02mm；Further；It is described
Thick bar periphery on be machined with multiple arcs pit；Further；The arc part of the quadrangle of elongate rod is along its length
It is machined with multiple grooves；Further；The length of the toroidal inductive signal slot is more than or equal to high pressure resistant close to switch sensing
The diameter of device mounting hole, when electromagnet retracts, face above and below toroidal inductive signal slot and mounting hole.
Positive advantageous effects of the invention are: being equipped on this electromagnet high pressure resistant close to switch biography
Sensor, with the toroidal inductive signal groove portion mutually incuded with high pressure resistant sensor, when valve rod movement, resistance to height in connecting rod
Pressure, which passes approach switch sensor, can generate inductive signal, and inductive signal can be used as the feedback signal of valve, this electromagnet is certainly
Body has feedback function, is directly mounted to form the hydraulic control system of automation on current common valve, without adopting again
With expensive dedicated hydraulic valve, used in installed common valve occasion can in the case where investing small, project amount very little it is real
Existing system has feedback control signal, and this electromagnet combines its cost price with common valve and is far below to have and feeds back function
Can dedicated hydraulic valve also can biggish saving capital investment, it is critical that this band so even if using in newly-built system
The simple combination of the electromagnet of feedback push rod and electromagnet frequently, because push rod is longer, and during pushing spool also
Need to overcome valve core spring pressure oil pressure variation generate pressure, how structure design it is bad if, connecting rod be easy hair
Life is stuck, and early period is less likely to occur stuck if the gap between connecting rod and hole is big, but positions bad, movement shakiness, is easy
Concentrated wear, the integral member service life is low, has good positioning if the gap between extension bar and hole is small in succession, if machining accuracy is not high
The extremely easy generation of words is stuck, so that connecting rod is born biggish pressure in movement if gap is small, is easily deformed, after deformation
It will lead to stuck, so that movement is failed, this connecting rod is positioned using hole B, the hole both ends C, and passes through special elongate rod cross sectional shape
Valve rod is born when pushing away spool pressure can either be can reduce, make to position in the lesser situation in gap between connecting rod and hole again
Good, motion stability, is not easy to deform it in use, and the groove in elongate rod, which opens up, not only ensure that positioning, but also reduces
Friction, moreover it is possible to be connected to oil circuit by groove, uniform force when acting connecting rod, motion stability adds on the thick bar circumference
Work arc hole can be used for oil storage, and resistance when reduction acts is connected between attachment base A and attachment base B using inner screw sheath,
It can guarantee that high pressure resistant approach switch sensor can be located at top forever during installation.
