At the same time, the first mounting hole 4 and the second mounting hole 5 are provided on the valve seat 1, so that the surface-mounted solenoid valve can also be connected to the actuator by plate connection. In other words, the installation method of the surface-mounted solenoid valve in the present disclosure can directly realize plate connection or pipe connection, and the installation method is changeable, which effectively meets the usage requirements of customers; it reduces the burden and cost of customers, and no adapter plate is needed, and the solution is simple.

[0022] As an optional embodiment, the surface-mounted solenoid valve further includes a first connector; the first connector is provided with a first connection hole for plugging a hose, and when the first connector is threadedly matched with the threaded portion inside the first air inlet 2, the first connection hole is connected to the first air inlet 2. The first connector is threadedly matched with the threaded portion inside the first air inlet 2, thereby realizing a convenient connection between the hose and the solenoid valve, and facilitating the introduction of gas; the provision of the first connector enables the solenoid valve to adapt to more types of pipeline connections, thereby increasing its wide application.

[0023] As an optional embodiment, the surface-mounted solenoid valve further includes a second connector; the second connector is provided with a second connection hole for plugging a hose, and when the second connector is threadedly engaged with the threaded portion inside the air outlet 3, the second connection hole is communicated with the air outlet 3. The design of the second connector allows the air outlet 3 to be connected to other devices or pipelines through a hose, thereby expanding the use function of the solenoid valve; and the hose connection method is convenient for disassembly and replacement when necessary, thereby reducing maintenance costs.

[0024] As an optional embodiment, the mounted solenoid valve further includes a coil housing 10, a static iron core assembly 8 and a moving iron core 6; the coil housing 10 is connected to the valve seat 1; the static iron core assembly 8 is installed in the coil housing 10 and has an exhaust port 9; the moving iron core 6 is movably installed inside the static iron core assembly 8, and stays in the first position and the second position according to whether the mounted solenoid valve is powered on or not; when the moving iron core 6 stays in the first position, the first air inlet 2 is connected to the air outlet 3, and the moving iron core 6 prevents the exhaust port 9 from being connected to the air outlet 3; when the moving iron core 6 stays in the second position, the exhaust port 9 is connected to the air outlet 3, and the moving iron core 6 prevents the first air inlet 2 from being connected to the air outlet 3. The introduction of the moving iron core 6 enables the solenoid valve to accurately control the flow of gas, and stays in different positions according to whether it is powered on or not, so as to realize the switching of the gas path; at the same time, the movable design of the moving iron core 6 ensures that the solenoid valve can still maintain a high reliability under frequent operation.

[0025] As an optional embodiment, the mounted solenoid valve further includes a reset spring 7, the two ends of which are respectively in contact with the static iron core assembly 8 and the moving iron core 6; when the mounted solenoid valve is powered off, the reset spring 7 drives the moving iron core 6 to move to the second position. The reset spring 7 enables the solenoid valve to automatically return to the second position after power failure, thereby improving the safety and stability of the system; at the same time, the automatic reset function solves the problem of continuous energy consumption of the solenoid valve when it does not need to work.

The actuator realizes the inflow and outflow of gas through the control of the surface-mounted solenoid valve. When the solenoid valve is energized, the moving iron core 6 is in a specific position, allowing gas to flow into the A chamber of the actuator from one port and discharge the gas from the B chamber of the actuator from another port. Conversely, when the solenoid valve loses power, the flow direction of the gas will change; by precisely controlling the flow of gas, they provide stable and reliable power support for various devices and systems. Under the control of the surface-mounted solenoid valve, the above-mentioned actuator can realize precise control and operation of the gas, so that the actuator in the present disclosure can be widely used in industrial automation, fluid control, medical equipment and other fields.

The actuator is tightly connected to the solenoid valve by the fasteners, which ensures the stability and safety of the system. At the same time, the design of the mounting holes and the fasteners makes the installation process of the actuator simple and quick.

[0030] It should be noted that a sealing ring is also provided between the actuator and the solenoid valve to ensure the sealing of the connection between the air outlet 3 and the second air inlet.

[0031] As an optional implementation, the actuator further includes a third connector and a hose; the third connector is threadedly connected to the second air inlet; and both ends of the hose are plugged into the second connector and the third connector respectively. The design of the third connector and the hose enables the actuator to adapt to more types of pipeline connections, increasing its wide application. The hose connection method is easy to disassemble and replace when necessary, reducing maintenance costs.

[0032] The working process of the execution device is as follows:

[0033] Depending on whether the mounted solenoid valve is energized or not, the moving iron core 6 stays in the first position (energized) and the second position (de-energized); when the moving iron core 6 stays in the first position (energized), the first air inlet 2 is connected with the air outlet 3, the air outlet 3 is connected with the second air inlet of the actuator, and at the same time, the exhaust port 9 is prevented from being connected with the air outlet 3 and the second air inlet of the actuator; when the moving iron core 6 stays in the second position (de-energized), that is, when the solenoid valve is de-energized, the reset spring 7 drives the moving iron core 6 to move to the second position, and the moving iron core 6 prevents the first air inlet 2 from being connected with the air outlet 3, and at the same time, the exhaust port 9 is connected with the air outlet 3 and the second air inlet of the actuator.
