Technical Field
The invention relates to the technical field of industrial automation, in particular to a general electromagnetic valve core action feedback device.
Background
Electromagnetic valves are electromagnetic control industrial equipment and are widely applied to hydraulic and pneumatic transmission systems. The control precision and flexibility can be effectively ensured by adjusting parameters such as the direction, the flow, the speed and the like of the medium in the industrial control system. However, due to the precise valve core structure of the electromagnetic valve, when the medium contains impurities, the electromagnetic valve is blocked, so that a medium loop is not communicated or a subordinate actuating mechanism is refused, and finally, the industrial control flow is failed. The liquid and gas mediums have flowability, and impurities which cause the jamming solenoid valve often flow back to a pipeline or a hydraulic groove when the fault is checked and repaired, so that the jam solenoid valve is extremely difficult to find; the solenoid valve is not provided with a valve element operation monitoring mechanism. Therefore, whether the electromagnetic valve is blocked or not or whether other faults exist in the system cannot be determined, and great difficulty and inconvenience are caused to fault detection.

Detailed Description
Example 1:
the invention relates to a general electromagnetic valve core action feedback device, which is shown in figures 1 to 3 and comprises a bracket, a screw, a spring, a bolt and the like which are used for fixing.
The bracket is made of metal materials, and can be processed by steel plates or iron plates or other high-strength engineering metal materials when in specific implementation.
The bottom of the bracket is designed according to the actual model of the field electromagnetic valve, and can be designed into a circular ring shape or a U shape, as shown in fig. 1, and the embodiment is a circular ring-shaped bracket. The support base 1 is of a circular ring structure, two support columns 5 are upwards connected to the outer side edges of two ends of the circular ring, the top ends of the two support columns 5 are connected with a transverse plate 4, the long side of the transverse plate 4 is upwards provided with an extension part, the extension part is a micro-switch installation area 3, and a sufficient space is reserved on the micro-switch installation area 3 for installing a micro-switch.
The bracket base 1, the bracket column 5, the transverse plate 4 and the extension part of the upper part of the transverse plate 4 are of an integral connection structure.
The transverse plate 4 is of a rectangular structure, and an opening is formed in the center of the transverse plate 4 and used for penetrating through the spring screw 2. The screw rod 2 is made of metal materials, the corresponding screw rod is processed according to the diameter of the on-site solenoid valve core monitoring hole, and threads can not be processed at the part of the screw rod plug 7 at the bottom of the screw rod, inserted into the solenoid valve core monitoring hole, so that friction resistance is reduced. The assembly mode of the screw rod 2 and the spring 9 is shown in the figure, the spring 9 passes through the screw rod 2 and is clamped between the gasket 8 and the nut 10, and the compression amount of the spring can be adjusted by rotating the nut 10 up and down so as to adjust the compression force of the spring and the length of the screw rod to meet the requirement of natural rebound of the spring.
The micro switch is arranged at the micro switch installation area 3 of the bracket 1, the type of the micro switch can be selected according to the actual situation of the site, and the normally open contact of the micro switch is sent to the control system through a signal cable.
The working mode of the device is as follows:
Firstly, a circular ring of a bracket base is sleeved outside a solenoid valve coil and is fixed by a solenoid valve self-carrying coil bolt, a screw plug 7 is penetrated into a solenoid valve core monitoring hole to be monitored and is tightly contacted with a baffle plate in the solenoid valve core monitoring hole, so that a valve core, a valve core baffle plate and a spring screw are integrally linked. When the electromagnetic valve acts, the valve core is attracted by the electromagnet to push the valve core baffle, and the spring screw rod 2 is compressed to extend the top of the screw rod. A micro switch installation area 3 is arranged on a support at the top of the screw rod, a micro switch is installed on the micro switch installation area 3, the screw rod presses the micro switch to close a normally open contact of the switch, and a valve core action signal is sent out. When the electromagnetic valve is in reverse action or recovery, the valve core acts to the other end, the screw rod is under the action of the elastic force of the spring and returns to the initial position, at the moment, the top end of the screw rod does not press the micro switch any more, and the action signal of the electromagnetic valve is recovered.
Example 2:
the bracket 1 is a U-shaped bracket, and the other parts are the same as those of the embodiment 1.
