Description

Technical Field

[0001] The utility model relates to the field of electromagnetic valves, in particular to a safety protection device based on electromagnetic valves. Background Art

[0002] At present, a Chinese utility model with announcement number CN218267503U discloses a solenoid valve protection device, which relates to the field of solenoid valve technology, including an upper shell and a lower shell, wherein the front and rear ends of the upper shell and the lower shell are both equipped with a semi-ring frame, and a reinforcement plate is installed between the upper shell, the lower shell and the semi-ring frame. The utility model is provided with an upper shell, a lower shell, a semi-ring frame, a reinforcement plate, a first soft protective layer, a second soft protective layer, a magnetic strip, a limit frame, a buckle, a pressure plate, and a positioning frame. The upper shell and the lower shell are provided with an external protection structure for the solenoid valve, and the first soft protective layer and the second soft protective layer are used to strengthen the protection function of the solenoid valve. The semi-ring frame and the reinforcement plate are used to strengthen the protection of the connection position between the solenoid valve and the pipeline. The magnetic strip is used to realize the opening and closing connection function of the upper shell and the lower shell. The limit frame, the buckle, the pressure plate and the positioning frame are used to realize the connection and fixing function of the upper shell and the lower shell. In this way, the solenoid valve can be fully wrapped and protected to prevent it from being damaged by impact.

[0003] The existing protective devices are not easy to install and disassemble. Generally, the protective devices are fixed and installed by bolts. When installing and disassembling them, tools are needed to disassemble and assemble them. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the efficiency of disassembly and assembly. It is not convenient to use and does not have an anti-pull function. The cable of the solenoid valve is generally directly passed through the threading hole on the protective shell. In this way, during use, if the cable is pulled, it is easy to break the connection between the cable and the solenoid valve, causing damage to the solenoid valve, thereby affecting use and reducing practicality. In order to solve the above problems, we propose a safety protection device based on a solenoid valve. Utility Model Content
