Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a solenoid valve. Background Art

[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids and belong to actuators. Solenoid valves can be used with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed. Different solenoid valves play a role in different positions of the control system. The most commonly used ones are check valves, safety valves, directional control valves, etc.

[0003] A patent search revealed that a solenoid valve with announcement number CN220337603U has wrapping components installed at the outer ends of the connecting components on both sides of the solenoid valve, and the wrapping components contain sponges. If the medium leaks at the connection between the connecting component and the external pipeline and flows into the sponge, the humidity of the sponge will be high. A humidity sensor is installed at the lower end of the wrapping component to monitor the humidity in the sponge. When the humidity is high, the humidity sensor sends a signal to the controller, which in turn turns on the warning light through the controller to illuminate, prompting the staff that there is a leak at the connection, thereby reducing the loss of the medium and economic losses and improving the functionality of the solenoid valve.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4, including: a solenoid valve body 1, an alarm 3 arranged inside the solenoid valve body 1, and a valve body connecting tube 2 installed on one side of the solenoid valve body 1, a plurality of mounting holes are arranged on the surface of the solenoid valve body 1, and a cavity is arranged inside the solenoid valve body 1, the alarm 3 is placed in the cavity, and the usage of the alarm 3 and the valve body connecting tube 2 is the same as that of the comparative document.

[0025] The detection opening 6 is provided at the bottom of the inner wall of the valve body connecting tube 2. The interior of the valve body connecting tube 2 is divided into two sections. One group is the internal threaded portion 4 arranged on the inner wall of the valve body connecting tube 2, and the other group is the water leakage detection portion 5 on one side of the internal threaded portion 4 and close to the opening of the valve body connecting tube 2. The inner diameter of the water leakage detection portion 5 is larger than the inner diameter of the internal threaded portion 4. In this way, an external pipeline can be connected through the internal threaded portion 4, and the external pipeline is combined with the internal threaded portion 4 to complete the combination of the external pipeline and the valve body connecting tube 2. After being combined with the external pipeline, the flowing medium enters the entire solenoid valve along the valve body connecting tube 2.

[0026] An assembly cylinder 7 is fixedly provided on the outer wall of the valve body connecting cylinder 2; the assembly cylinder 7 is of a cylindrical structure and is hollow inside. The top of the assembly cylinder 7 is connected to the detection opening 6, and a sponge plug 9 can be filled in the hollow inside of the assembly cylinder 7, and a docking socket 8 is opened at the top of the assembly cylinder 7. The docking socket 8 is connected to the channel of the detection opening 6, and a protrusion is provided on the top of the sponge plug 9. After the sponge plug 9 is assembled in the hollow of the assembly cylinder 7, the protrusion enters the detection opening 6 along the docking socket 8, and the other part of the sponge plug 9 is retained in the interior of the assembly cylinder 7. When water leakage occurs, the sponge plug 9 will be soaked.

[0027] The external thread of the assembly tube 7 is installed with a sealing sleeve 10, and the sealing sleeve 10 is plugged with a humidity sensor 11, wherein the test end of the humidity sensor 11 extends into the cavity of the sealing sleeve 10. When the sealing sleeve 10 is combined with the assembly tube 7, the test end of the humidity sensor 11 moves upward synchronously, and a socket portion 12 is provided at the bottom of the sponge plug 9. The top test end of the humidity sensor 11 extends upward through the sealing sleeve 10 and is plugged and adapted to the socket portion 12, so that the test end of the humidity sensor 11 accurately extends into the interior of the socket portion 12, and the sponge plug 9 is wetted. After that, the detection is carried out quickly, and the humidity sensor 11 is connected to the alarm 3 by a controller. Similar to the comparative document, a sleeve outer stopper 13 is fixedly arranged on the outer wall of the sealing sleeve 10. The fixed sleeve outer stopper 13 facilitates the use of a tool to rotate the sealing sleeve 10. After the sealing sleeve 10 is threadedly sleeved on the assembly tube 7, the entire device can isolate the test end of the humidity sensor 11 and the sponge plug 9 from the outside, so that the detection of the sponge plug 9 and the humidity sensor 11 can be more accurate, which greatly reduces the error caused by the external environment to the detection of the humidity sensor 11.
