Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a pile end one-way non-return grouting valve. Background Art

[0002] As we all know, a check valve is a valve that automatically opens and closes the valve disc depending on the flow of the medium itself to prevent the medium from flowing back. It is also called a non-return valve, a one-way valve, a reverse flow valve, and a back pressure valve. A check valve is an automatic valve. Its main function is to prevent the medium from flowing back, to prevent the pump and the drive motor from reversing, and to release the container medium. The check valve can also be used on the pipeline to provide supply to the auxiliary system where the pressure may rise to exceed the system pressure. Check valves can be mainly divided into swing check valves and lift check valves.

[0003] In various types of building construction, grouting holes are opened on the building according to construction needs, and then the check grouting valve is inserted into the grouting hole. The sealing between the check grouting valve and the grouting hole currently in practical use is not strong, which makes it easy for cement slurry to seep out and affect the grouting effect. In addition, the check grouting valve has poor stability in the grouting hole and is easy to fall off during the grouting process. Utility Model Content
