[0026] See also Figure 1-6 , an integrated water injection pump skid, including a driving device 101 and a pump body 102 connected to the driving device 101, one side of the pump body 102 is connected to a connecting pipe 103, and the connecting pipe 103 is connected to other water supply pipes through the connecting disk 104 above, so as to transport water flow, and one end of the connecting pipe 103 is connected to the connecting disk 104, and a step portion 105 is provided on one side of the connecting disk 104. By providing the step portion 105, the sealing performance when connected to other pipes can be increased, and the connecting disk 104 is provided with an inner annular groove 106 and an outer annular groove 107. The inner annular groove 106 is located in the step portion 105, and has a double sealing effect through the cooperation of an inner sealing ring 108 and an outer sealing ring 109. The inner annular groove 106 is provided with an inner sealing ring 108, and the outer annular groove 107 is provided with an outer sealing ring 109;

[0027] refer to Figure 4 and Figure 5, the connecting plate 104 is provided with a movable plate 110 at one end close to the connecting pipe 103. When installing, the connecting plate 104 is connected to the flange of the water supply pipe with bolts. The bolts pass through the flange of the water supply pipe, the connecting plate 104 and the movable plate 110 in sequence, and then are fixed with nuts. The connecting plate 104 and the movable plate 110 are provided with through holes that penetrate each other, and the through holes are used for the bolts to pass through. A cavity 111 is provided in the connecting plate 104, and one side of the movable plate 110 is connected with a hole that penetrates the cavity 111 and reaches the outer annular groove 107 The moving rod 112, when the moving plate 110 moves, will push the outer baffle 113 to move, thereby pushing the outer sealing ring 109 to move. One end of the moving rod 112 is connected to the outer baffle 113, and the outer sealing ring 109 is connected to one side of the outer baffle 113. When in use, the inner sealing ring 108 and the outer sealing ring 109 will be located in the inner annular groove 106 and the outer annular groove 107, and will not affect the installation of the two flanges. When the nut is tightened, the outer sealing ring 109 will move toward the flange at the other end, thereby playing a sealing role.

[0028] When in use, the outer sealing ring 109 will be located in the outer annular groove 107 on the side away from the movable plate 110, which will affect the installation of the flange and the connecting plate 104. The following structure is provided to reduce the impact: Specifically, refer to Figure 4 and Figure 5 The moving rod 112 is located on the side wall of the cavity 111 and is connected to an extrusion plate 114.
