Technical field
The present invention relates to technical field of automation in industry, more particularly to a kind of general valve core of the electromagnetic valve action feedback dress
Put.
Background technology
Magnetic valve is Electromagnetic Control industrial equipment, is widely used in hydraulic pressure, pneumatic gearing system.In industrial control system
Parameter, the precision of control and the flexibilities such as the middle direction for adjusting medium, flow, speed can be effectively ensured.But due to electromagnetism
Valve core construction is accurate, can cause magnetic valve bite when containing impurity in medium, causes medium loop obstructed or subordinate performs
Mechanism tripping, ultimately result in the failure of industry control flow.And liquid, gas class medium have flowable, when malfunction elimination overhauls, cause card
The impurity of puckery magnetic valve often flows back to pipeline or hydraulic pressure groove, it is extremely difficult to finds；And magnetic valve does not possess valve element action MA monitoring agency.
Therefore it can not determine that whether because bite tripping, or system have other failures, very big difficulty is caused to malfunction elimination for magnetic valve
And inconvenience.
The content of the invention
To overcome defect present in above-mentioned prior art, the present invention provides a kind of general valve core of the electromagnetic valve action feedback
Device, it is a kind of simple and reliable for structure its purpose is to provide, magnetic valve emotionally condition can be effectively monitored, and can carry significantly
The valve core of the electromagnetic valve action feedback device of high failture evacuation rate.
In order to realize foregoing invention purpose, the present invention is achieved in the following ways：
A kind of general valve core of the electromagnetic valve action feedback device, is to have connected up two stent struts in bracket base outer side edges,
The top connection transverse slat of two stent struts, the long side of transverse slat are provided with prolongation upwards, and the prolongation is installed for microswitch
Region, enough spaces is left on microswitch installation region, for installing microswitch；The center of transverse slat is provided with perforate, uses
It is screw rod plug to come through spring spiro rod, screw rod bottom, and spring passes through screw rod, is clipped between packing ring and nut, by nut
Lower turn, amount of spring compression is adjusted, to adjust pressing force of the spring and spiro rod length.
The bracket base is cirque structure or U-shape structure.
The transverse slat is rectangle structure.
The screw rod is made up of metal material.
The bracket base, stent strut, transverse slat and the prolongation on transverse slat top are integrated the metallic steel of attachment structure
Plate is process.
The bracket base, stent strut, transverse slat and the prolongation on transverse slat top are process by steel plate.
Advantages of the present invention and beneficial effect are：
The present invention has the features such as simple and reliable for structure, reasonable in design.Spring can be connected by simple and reliable transmission mechanism
Bar and valve core of the electromagnetic valve are in close contact, and drive spring link action when valve core of the electromagnetic valve action, involution.Further, since spring connects
Bar upper end is provided with microswitch, therefore microswitch can return to feedback signal control system, and control system can be remembered
The realistic operation situation of magnetic valve is recorded, is inquired about by history bulletin, you can the quick original for determining or excluding executing agency's tripping
Because whether being caused by magnetic valve bite.Electromagnetism valve events situation can be effectively monitored, while substantially increases the effect of failture evacuation
Rate.
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is further detailed explanation, but not by the present embodiment institute
Limit.
Brief description of the drawings
Fig. 1 the structural representation of present invention；
Fig. 2 is Fig. 1 side view；
Fig. 3 is Fig. 1 top view.
In figure：Bracket base 1, screw rod 2, microswitch installation region 3, transverse slat 4, stent strut 5, screw rod plug 7, packing ring 8,
Spring 9, nut 10.
Embodiment
Embodiment 1：
The present invention is a kind of general valve core of the electromagnetic valve action feedback device, and as shown in Figure 1 to Figure 3, it includes being used for fixing
The part such as the support of effect, screw rod, spring, bolt forms.
The support is made up of metal material, and steel plate can be selected during specific implementation and be process, also can be selected iron plate or
Other high-strength work metal materials.
The bottom of support may be designed as annular or U-shaped, as shown in figure 1, should according to the actual type design of live magnetic valve
Embodiment is annular stent.Bracket base 1 is cirque structure, and at annulus both ends, outer side edges have connected up two stent struts
5, the top connection transverse slat 4 of two stent struts 5, the long side of transverse slat 4 is provided with prolongation upwards, and the prolongation is microswitch
Installation region 3, enough spaces is left on microswitch installation region 3, for installing microswitch.
The bracket base 1, stent strut 5, transverse slat 4 and the prolongation on the top of transverse slat 4 are integrated attachment structure.
The transverse slat 4 is rectangle structure, and the center of transverse slat 4 is provided with perforate, for through spring spiro rod 2.Screw rod 2 is gold
Category material is made, and processes respective threaded rod according to the diameter of live valve core of the electromagnetic valve Judas-hole, the screw rod plug 7 of screw rod bottom inserts
The part of valve core of the electromagnetic valve Judas-hole can not process screw thread, with reducing friction resistance.Screw rod 2 is with the assembly method of spring 9 as schemed
Showing, spring 9 passes through screw rod 2, is clipped between packing ring 8 and nut 10, by nut turn about 10, can adjust amount of spring compression,
To adjust pressing force of the spring and spiro rod length, to meet the requirement of spring nature resilience.
The microswitch, at the microswitch installation region 3 of support 1, microswitch model can be according to scene
Actual conditions select, and microswitch normal opened contact delivers to control system by signal cable.
The working method of apparatus of the present invention is：
The annulus of bracket base is enclosed on outside electromagnetic valve coil first and fixed with magnetic valve self brought line circle bolt, by screw rod plug
7 penetrate monitored valve core of the electromagnetic valve Judas-hole, are in close contact with valve core of the electromagnetic valve Judas-hole Internal baffle, form valve element, valve element
Baffle plate, the entirety of spring spiro rod three linkage.Valve element is attracted by electromagnet during electromagnetism valve events, promotes valve element baffle plate, compression
Spring spiro rod 2, extends screw tip.Microswitch installation region 3 is provided with the support of screw tip, is pacified in microswitch
Microswitch is installed on dress region 3, screw rod compressing microswitch, closure switch normal opened contact, sends out valve element action signal.Electricity
When magnet valve counteragent or recovery, valve element is acted to the other end, screw rod and acted on by spring force, returns to initial position, now spiral shell
No longer oppress microswitch, magnetic valve action signal involution in bar top.
Embodiment 2：
The support 1 is U-shaped support, and the other the same as in Example 1 is identical.
