[0026] See also Figure 1-7 The utility model provides a technical solution: a multifunctional check valve, comprising a valve body 1, a fixed seat 2 is fixedly connected to the top of the valve body 1, a sealing ring 3 is connected to the top of the fixed seat 2, a valve stem 4 is plugged into the top of the fixed seat 2, a rocker 5 is fixedly connected to the top of the valve stem 4, a fixed pipe 6 is fixedly connected to the left and right sides of the valve body 1, a flange 9 is fixedly sleeved on the outer edge of the fixed pipe 6, and a plurality of flange holes 7 are opened on the flange 9;
[0027] A disc 8 is provided on the side of the flange 9 close to the fixed pipe 6, and a hexagonal groove 10 is opened on the disc 8. A connecting plate 12 is fixedly connected to the side of the disc 8 away from the fixed pipe 6. Four grooves 11 are opened on the outer edge of the flange 9, and the connecting plate 12 is movably inserted in the inner cavity of the adjacent groove 11. An annular groove 14 is opened on the side of the flange 9 away from the fixed pipe 6, and the annular groove 14 corresponds to the adjacent flange hole 7. A ring 13 is movably inserted into the inner side of the annular groove 14, and the ring 13 is fixedly connected to the adjacent connecting plate 12. The thickness of the ring 13 is less than the depth of the annular groove 14, and the ring 13 is flush with one side of the connecting plate 12. The horizontal distance between the disc 8 and the flange 9 is greater than the depth of the annular groove 14, the connecting plate 12 and the groove 11 match each other, and the ring 13 and the annular groove 14 match each other.
[0028] Working principle: During use, before the valve body 1 is connected to the external pipe, first move the disc 8, the connecting plate 12 and the ring 13 as a whole, and move the whole to the outer edge of the flange 9 on the valve body 1, and then move the disc 8, the connecting plate 12 and the ring 13 as a whole, so that the ring 13 and the side of the flange 9 away from the fixed pipe 6 fit each other, and then move the disc 8, the connecting plate 12 and the ring 13 as a whole toward the center of the flange 9 until the connecting plate 12 moves to the inner cavity of the groove 11, and then move the disc 8, the connecting plate 12 and the ring 13 as a whole horizontally, so that the ring 13 moves to the inner cavity of the annular groove 14, thereby completing the installation of the disc 8, the connecting plate 12 and the ring 13;
[0029] After that, the flange on the external pipe is aligned with the flange 9 of the device, and a sealing gasket can be placed in the middle. Then, the screw is passed through one side of the hexagonal groove 10, and through the flange hole 7 and the ring 13 at the same time, so that one end of the hexagonal nut of the screw is inserted into the hexagonal groove 10. The screw also passes through the flange hole on the external pipe, and then the nut is put on. At this time, one end of the hexagonal nut of the screw is inserted into the hexagonal groove 10. There is no need to fix the screw with a wrench, and the nut can be rotated with a wrench.
