The rotation of the motor 51 will cause the telescopic valve stem 7 to move, driving the valve core to move accordingly, thereby controlling the passage of the fluid. This process is a prior art);

[0024] The ventilation structure 6 includes an installation frame 61 arranged on the left and right sides of the top cover 5 and a pump body 62 installed inside the installation frame 61. One end of the pump body 62 is connected to the intake pipe 63, and the opening of the intake pipe 63 is located on the outside of the installation frame 61. The interior of the intake pipe 63 is provided with a filter screen 64 and a silica gel desiccant 65. The filter screen 64 and the silica gel desiccant 65 respectively play the role of filtering and drying. The end of the pump body 62 away from the intake pipe 63 is connected to a conduit 66. The upper and lower sides of the conduit 66 are provided with a diversion pipe 67. One side of the conduit 66 and the two groups of diversion pipes 67 are connected to an air expansion hood 68. When the pump body 62 is started, air can enter the conduit 66 and the diversion pipe 67 from the intake pipe 63, and finally be discharged from the air expansion hood 68, which can blow air to the motor 51, realize the ventilation effect, and cool the motor 51.

[0025] There are two groups of ventilation structures 6 , which are symmetrically distributed about the center line of the top cover 5 . The wind blown out by the two groups of ventilation structures 6 can be convected, so that the temperature distribution in the installation frame 61 and the top cover 5 is uniform.

[0026] Sound-absorbing cotton 611 is provided on the inner wall of the installation frame 61 . The sound-absorbing cotton 611 is used to absorb noise, so that the noise generated by the installation frame 61 is absorbed, and the noise reduction effect is good.

[0030] Example 2: This example is an improvement made on the basis of Example 1. For details, please refer to Figure 4 A hinge shaft 21 is installed on the inner wall of the water inlet pipe 2, and a pressure reducing plate 22 is provided on one side of the hinge shaft 21.

Mounting columns 23 are installed on the inner wall of the water inlet pipe 2 and the side wall of the pressure reducing plate 22. A spring member 24 is provided between the two groups of the mounting columns 23. When water flows into the water inlet pipe 2, it can impact the pressure reducing plate 22. With the help of the elasticity of the spring member 24, the pressure of the water flowing into the water inlet pipe 2 can be reduced to avoid damage to the valve body 1.

[0031] In this embodiment: when in use, water can flow into the valve body 1 from the water inlet pipe 2. At this time, the water flow will impact the pressure reducing plate 22, and the spring member 24 will be compressed. The cooperation between the pressure reducing plate 22 and the spring member 24 can block the pressure of the water flow impact, so that the water pressure entering the valve body 1 becomes smaller, thereby avoiding damage to the valve body 1 caused by excessive water pressure.

[0032] Working principle: Starting the pump body 62 can allow air to enter the duct 66 and the diversion pipe 67 from the intake pipe 63, and finally be discharged from the air expansion hood 68, which can blow air to the motor 51. At the same time, the filter screen 64 and silica gel desiccant 65 can be used to filter and dry the inhaled air, and moisture in the air can be removed. The wind blown out by the two sets of ventilation structures 6 can form convection, so that the temperature distribution in the installation frame 61 and the top cover 5 is uniform, and the sound-absorbing cotton 611 is used to reduce noise. Air can be discharged from the breathable net 52, and the activated carbon layer 53 can be used to remove moisture. Water can flow into the valve body 1 from the water inlet pipe 2. At this time, the water flow will impact the pressure reducing plate 22, and the spring part 24 is compressed. The cooperation of the pressure reducing plate 22 and the spring part 24 can block the pressure of the water flow impact, so that the water pressure entering the valve body 1 becomes smaller.
