The height of the caisson directly affects the length of the valve stem, and opening and closing rely on special devices and must be rotated manually. Therefore, the traditional caisson water pressure site operation is cumbersome. Each ball valve is equipped with a valve stem. The quality and precision of the valve stem processing directly affect whether the ball valve can be successfully opened and closed. There are many people involved, the human operation factor has a greater impact, the offshore operation time is longer, and the safety risk of caisson water pressure is greater. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the present invention provides a support and lifting process for a caisson water pressurizing solenoid valve, which improves the caisson water pressurizing efficiency, reduces the impact of human operation on water pressurizing, reduces the input of water pressurizing personnel, and reduces the safety risk of caisson water pressurizing.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts a support and hoisting process for a caisson water pressure solenoid valve, comprising the following steps:

[0005] S1. First, on the inner side of the flanges at the water inlet and outlet ends of the solenoid valve, each end is connected to the valve body of the solenoid valve through two U-shaped steel plates, and the two U-shaped steel plates are connected by the fastening bolts at the bottom; two upper angle steels are welded on the inner side of the bottom of the U-shaped steel plates, and the upper angle steels are connected to the lower angle steels by bolts; in the direction of the water inlet channel, the end of the lower angle steel is connected to the bottom angle steel by welding;

[0006] S2. Then connect the two wings on the outside of the U-shaped steel plate at the bottom of the solenoid valve to the connecting screw by welding, and connect the upper end of the connecting screw to the connecting steel plate at the top of the solenoid valve. After the connection is completed, the connecting steel plate at the top and the support frame are assembled as a whole; install the ear plate in the middle of the connecting steel plate along the direction of the water inlet channel;

[0007] S3. Finally, a steel wire rope is used to connect the lifting lug to move, adjust or install the solenoid valve.

[0008] The upper angle steel of step S1 is provided with a connecting hole, and the lower angle steel is provided with an adjusting hole. During installation, the installation positions of the upper angle steel and the lower angle steel are adjusted by cooperating with the connecting hole and the adjusting hole;

[0009] In the step S1, when installing the lower angle steel, the tip corner of the lower angle steel needs to be cut off;

[0010] In step S2, a hole is reserved in the middle of the connecting steel plate for connecting the top bolt of the solenoid valve, ensuring that the connecting steel plate is horizontal and vertically connected to the connecting screw rod;

[0011] The four corners of the connecting steel plate located at the top of the solenoid valve are provided with reserved bolt holes, and the connecting steel plate and the connecting screw rod are connected by connecting bolts;
