In order to increase the sealing effect between the valve core 4 and the cavity 11 in this embodiment, the valve core 4 may be designed as a circular truncated cone, a sealing member 41 may be wrapped on the conical surface of the valve core 4, and the sealing member 41 is preferably made of a polymer material such as rubber; in order to prevent the sealing member 41 from falling off from the valve core 4, a rib 42 may be added to the valve core 4; however, the rib 42 is not necessarily a structure, and functions to make the sealing member 41 better fitted on the tapered surface of the valve element 4, and the rib 42 may be omitted in manufacturing.

In this embodiment, the diameter of the stopper 52 is larger than that of the through hole of the bracket 5, when the valve core 4 is not acted by an external force, the valve core 4 is not in contact with the cavity 11 due to the action of the second spring 53, and the check valve is in a normally open state; the liquid in the cavity 11 can freely flow from the end of the second flange 13 to the end of the first flange 12; but when the liquid in the cavity 11 reversely flows from the end of the first flange 12 to the end of the second flange 13, because of the pressure effect of the liquid; and a valve core 4 in the one-way valve is closed with the valve body 1 to prevent liquid from flowing backwards.

A snap ring 6 is further fixedly mounted at the end close to the first flange 12 on the cavity 11, a thrust ring 7 is arranged between the permanent magnet 2 and the snap ring 6 in the cavity 11, a first spring 71 is arranged between the thrust ring 7 and the snap ring 6, one end of the first spring 71 is fixedly connected with the snap ring 6, and the other end of the first spring 71 is fixedly connected with the thrust ring 7.

Wherein, the number of turns of the coil 3 is set to be n turns, and n is more than 1. When two connecting lines of two end parts of the first flange 12 and two end parts of the second flange 13 are perpendicular to a horizontal line, the second flange 13 is ensured to be positioned below the first flange 12.

In this embodiment, two end portions of the first flange 12 are parallel to two connecting lines of two end portions of the second flange 13, and when the two connecting lines are parallel to a horizontal line, the cavity 11 of the check valve is slightly inclined upward in order to increase the reliability of the check valve, and an included angle θ is formed between the axis of the cavity 11 and the connecting lines, i.e., the horizontal line.

When the liquid flows through the cavity 11, the permanent magnet 2 rolls in the cavity 11 towards the end of the first flange 12 due to the impact force of the liquid; however, because the permanent magnet 2 is provided with a plurality of through holes, the situation of irregular pressure relief can occur, so that the permanent magnet 2 rotates in the cavity 11 at high frequency, the magnetic field generated by the permanent magnet 2 moves at high frequency, which is equivalent to that the coil 3 cuts magnetic induction lines at high frequency, and current is generated in the coil 3. The current is collected and sorted, and in the prior art, the electric energy in the coil 3 is stored in a storage battery through components such as a power amplifier, a current converter, a controller and the like, so as to supply power to other related devices.

In order to improve the efficiency of cutting the magnetic induction lines by the coil 3, the shape of the permanent magnet 2 can be selected to be a bar magnet, and the number of the bar magnets is more than or equal to 1; the outer face of the permanent magnet 2 is wrapped by the ball body 23, and rubber can be preferably selected as the material of the ball body 23, so that the sealing performance is improved, and the vibration is reduced. Because the permanent magnet 2 can move back and forth in the cavity 11, sometimes the permanent magnet can touch the cavity 11 at one end close to the first flange 12; in order to increase the motion amplitude of the permanent magnet 2 in the cavity 11, a clamping ring 6 is fixedly arranged at one end of the cavity 11 close to the first flange 12; in the cavity 11, the snap ring 6 is fixedly connected with one end of the first spring 71, and the thrust ring 7 is fixedly connected with the other end of the first spring 71. If the permanent magnet 2 collides with the thrust ring 7, the first spring 71 is compressed, and the elastic force generated by the first spring 71 causes the permanent magnet 2 to move in the opposite direction, thereby acting to buffer and increase the disturbance of the permanent magnet 2.

It should be noted that although an included angle θ exists between the axis of the cavity 11 and the horizontal line in this embodiment, the two end portions of the first flange 12 are parallel to the two connecting lines at the two end portions of the second flange 13, respectively, the two connecting lines are parallel to the horizontal line, and the axis of the bolt holes of the first flange 12 and the second flange 13 is parallel to the horizontal line, such that the cavity 11 is inclined, but the end surfaces of the first flange 12 and the second flange 13 are still perpendicular to each other, so that the check valve can be conveniently installed on the horizontal line; thereby overcoming the technical problem that the horizontal pipeline can not be provided with the one-way valve with the power generation function.

In addition, the check valve with power generation function according to another embodiment of the present invention can be further installed on a vertical pipeline, the two end portions of the first flange 12 are parallel to two connecting lines at the two end portions of the second flange 13, respectively, the two connecting lines are perpendicular to a horizontal line, an included angle θ is formed between the axis of the cavity 11 and the connecting lines, and it is sufficient to ensure that the second flange 13 is below the first flange 12 during installation; the power supply device has a large applicable scene and can meet the power supply problem of certain low-power-consumption electric appliances under severe working conditions.

The utility model also provides a power generation device without the function of the check valve, the structure of which is similar to that of the power generation device in the embodiment, as shown in fig. 4, when only the power generation function is kept, the components such as the valve core 4, the valve rod 51, the bracket 5, the second spring 53 and the like can be removed; the essential parts are as follows: the valve body 11, the permanent magnet 2 and the coil 3 have the same power generation principle as described above, and are not described herein.

Further, if the length of the cavity 11 is large, and the permanent magnet 2 does not touch the cavity at the end of the cavity 11 close to the first flange 12, the thrust ring 7, the first spring 71, and the snap ring 6 may be removed, so that the check valve is simplified, and is suitable for some application scenarios.

The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the above modifications or changes to the equivalent embodiments with equivalent changes, without departing from the technical spirit of the present invention, and any simple modification, equivalent change and change made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the technical spirit of the present invention.
