[0024] Furthermore, an adjusting mechanism is provided on the surface of the valve body 1, and the adjusting mechanism includes a movable frame 3, the movable frame 3 is arranged directly below the valve body 1, a guide rod 31 is fixedly connected to the surface of the movable frame 3, a lifting plate 32 is slidably connected to the surface of the guide rod 31, a hydraulic cylinder 33 is fixedly connected to the surface of the movable frame 3, the bottom of the lifting plate 32 is fixedly connected to the piston rod of the hydraulic cylinder 33, a movable rod 34 is fixedly connected to the surface of the lifting plate 32, a connecting plate 35 is fixedly connected to the surface of the movable rod 34, and the connecting plate 35 is fixedly connected to the surface of the valve body 1. Some larger valve bodies 1 need to be installed on ships using a crane during installation, but some spaces inside the ship are not suitable for using a crane. The adjusting mechanism can adjust the horizontal height and position of the valve body 1, thereby facilitating the installation of the valve body 1 and improving the installation efficiency of the valve body 1.

[0025] Furthermore, the storage pipe 21 is inclined, and the storage pipe 21 is connected to the interior of the valve body 1. An external thread is provided at one end of the storage pipe 21 away from the valve body 1, and a pipe cover 22 is threadedly connected to the external thread of the storage pipe 21. One end of both sides of the valve body 1 is an inlet pipe, and the other end is a water outlet pipe. The storage pipe 21 is fixedly connected to the water inlet pipe of the valve body 1, and the storage pipe 21 is located in front of the filter screen 2. The storage pipe 21 is equipped with a pipe cover 22 for storing larger impurities. The pipe cover 22 can be removed from the storage pipe 21, so as to discharge the impurities inside the storage pipe 21.

[0026] Furthermore, the rotating rod 24 is driven to rotate inside the valve body 1 through the output shaft of the motor 23, and the guide plate 25 is rotated inside the valve body 1 through the rotating rod 24. The guide plate 25 is located directly above the storage tube 21.

[0027] Furthermore, the guide plate 25 is composed of a plurality of groups of semicircular sectors, and the semicircular sectors are evenly arranged in a ring shape on the rotating rod 24. The radius of the guide plate 25 is smaller than the inner circle radius of the valve body 1. The guide plate 25 rotates counterclockwise inside the valve body 1.

The guide plate 25 rotates counterclockwise inside the valve body 1. The guide plate 25 will block larger impurities. During the rotation process, the guide plate 25 guides the impurities to the inside of the storage tube 21. The impurities inside the storage tube 21 can be cleaned up through the pipe cover 22, which prevents the impurities from following the fluid to hit the filter 2, thereby ensuring the safety of the use of the filter 2 and extending the service life of the filter 2.

[0031] By moving the frame 3 to change the position of the guide rod 31, the guide rod 31 is provided to the lifting plate 32, the movable rod 34, and the connecting plate 35 to change the position of the valve body 1.
