Description

Technical Field

[0001] The utility model relates to the technical field of check valve reinforcement devices, in particular to a check valve reinforcement device. Background Art

[0002] As we all know, the check valve is an automatic valve, whose main function is to prevent the backflow of the medium, the reverse rotation of the pump and the drive motor, and the discharge of the container medium. The check valve can also be used to provide supply to the auxiliary system where the pressure may rise to exceed the system pressure.

[0003] In real life, check valves are used in every household in cities and rural areas. The check valve joint of the check valve is connected to the external water pipe joint of the external water pipe. During use, the check valve and the connected water pipe are often hit by external force and shake. Since the check valve joint and the water pipe are not arranged as a whole, when the water pipe is hit, the connection between the check valve joint and the water pipe is greatly affected. After long-term use, the external water pipe joint and the check valve joint may become loose or shifted. The existing check valve does not have reinforcement measures that can stabilize the connection between the external water pipe joint and the check valve joint to maintain a long-term and firm connection. Therefore, the fixing effect is not very good and there is still room for improvement. Utility Model Content

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a check valve reinforcement device, which has the following beneficial effects:

[0015] The check valve reinforcement device, by threading a fixing ring on the fixing pipe and then threading the fixing ring with bolts and nuts, can enable the connecting plate to exert greater pressure on the clamping block, thereby achieving a better fixing effect on the connecting pipe. When the connecting pipe is impacted by an external force, the shaking caused by the impact force will directly terminate at the clamping plate without affecting the connection between the connecting pipe and the fixing pipe, thereby improving a certain fixing effect.
