Description

Technical Field

[0001] The utility model relates to the technical field of detection, and in particular to a detection circuit structure and a detection device. Background Art

[0002] A solenoid valve is a common device in industrial production processes, used to control the flow of liquid or gas. It mainly consists of two parts: an electromagnet and a valve body. Its working principle is simple. When the coil is energized, a magnetic field is generated, which attracts the iron core on the valve body to move. The iron core drives the valve stem to open or close the valve.

[0003] In actual applications, since the solenoid valve body often does not have a valve position detection function, and some solenoid valves are integrated into the internal equipment, it is impossible to effectively judge the actual status of the solenoid valve. Often, the only way to judge whether the solenoid valve is energized and working normally is to touch the coil with your hand and feel the temperature of the coil. However, this detection is intermittent and cannot be done in real time, which brings great inconvenience to daily maintenance work, especially for more important solenoid valves (such as steam turbine AST solenoid valves). If the solenoid valve coil failure is not discovered in time, there is a risk of unit tripping. Utility Model Content

[0023] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many other forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1-2 As shown, in an embodiment of a detection circuit structure, the detection circuit structure is used to detect the working state of the solenoid valve, including a switch element 2 and a collection component. The switch element 2 and the signal transmitting module are connected by a conductive wire. The switch element 2 can sense the magnetism of the coil 1 in the solenoid valve and turn on the circuit when the coil 1 is energized and has magnetism. The collection component is used to obtain the on-off state of the switch element 2.

[0027] In this embodiment, by setting up a device that can sense and detect magnetism, the circuit can be turned on when the coil 1 is energized when the solenoid valve is working normally. After the circuit is turned on, the acquisition component can obtain the on-off state of the switch 2, thereby realizing the function of monitoring the working condition of the solenoid valve coil 1, and solving the technical problem that it is difficult for existing solenoid valves to detect whether they are working normally.

[0028] In one embodiment of the detection circuit structure, the switch element 2 is a reed switch.

[0029] In this embodiment, the reed switch is an electronic component that uses the magnetic change of a reed to achieve switching control. It includes a glass tube, two reeds and filling gas. The magnetic change of the reed can control the conduction state of the reed switch through the action of an external magnetic field, thereby being used to detect the working state of the solenoid valve.

[0030] In addition, the switch element 2 can also be a relay. The magnetic force generated by the normal operation of the electromagnetic valve can make the relay conductive, thus achieving the effect of the relay monitoring the electromagnetic valve.

[0031] In one embodiment of the detection circuit structure, the acquisition component is a DCS system 3. Both ends of the switch 2 are connected to the DCS control system to detect the on / off status of the switch 2. When the switch 2 is open, it indicates that the solenoid valve coil 1 is not energized or is damaged. When the switch is closed, it indicates that the solenoid valve coil 1 is normally energized.

[0032] In an embodiment of a detection circuit structure, the acquisition component includes a power supply 4 and a signal module. The power supply 4, the signal module and the switch element 2 are connected in series. The signal module is used to send a signal to inform the switch element 2 of the on / off state.

[0033] In this embodiment, specifically, the signal module can inform the staff by emitting light, sound, vibration, etc. When the switch element 2 senses the magnetism of the solenoid valve coil 1, it can emit light, sound, or vibration to send a signal.

[0034] Specifically, the signal module can be a light emitting element 5, a buzzer or a vibration motor, wherein the light emitting element 5 can be a light bulb or a light emitting diode.

[0035] The utility model also relates to a detection device, comprising the detection circuit structure in the foregoing embodiment. The detection device further comprises a housing, and the detection circuit structure is mounted on the housing.

[0036] By applying the detection circuit structure in the previous embodiment, together with the housing, a portable detection device can be assembled, which is convenient for on-site staff to hold and detect the solenoid valve coil 1. When the detection device is close to the energized and magnetic solenoid valve coil 1, it will issue an indication, such as light, sound or vibration, indicating that the coil 1 is working normally. Otherwise, it means that the coil 1 is not energized or the coil 1 is damaged.

[0037] In an embodiment of the detection device, a receiving space is provided in the shell, a connecting hole is provided on the shell to connect the receiving space with the outside, and the signal module is passed through the connecting hole to be exposed to the outside.

[0038] In this embodiment, an internal receiving space can be provided to prevent the detection circuit structure from being exposed to the outside world and to avoid damage to the circuits and components. A connecting hole can be provided to facilitate the signal module to pass through and generate an alarm.

[0039] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
