AI Technical Summary
Technical Problem
When adjusting the overflow pressure, existing overflow valves need to use tools to lock and adjust the nut, and it is prone to loosening problems, resulting in unstable overflow pressure.
Method used
An overflow valve including a valve body, a valve needle, an adjustment plate, a moving block, a rotating sleeve and a T-plate is designed. The pressure adjustment of the valve needle is achieved through sliding connection and the fit of the spring, and the fit of the rotating sleeve and the screw is prevented from loosening and simplified operation.
Benefits of technology
The need for locking and adjustment with the help of tools is avoided, the operation is simplified, the stability and convenience of overflow pressure is ensured, and the problem of loosening is avoided.

Abstract
The utility model provides an overflow valve, which belongs to the field of overflow valves, and comprises a valve body, an overflow pipe, a valve rod, a valve rod and a valve rod, the valve needle is capable of adjusting pressure and preventing looseness, an annular valve seat is installed in the valve body, the valve needle extends into the annular valve seat and abuts against the annular valve seat in a sealed mode, an adjusting plate connected with the valve needle is connected into the valve body in a sealed and sliding mode, a moving block is connected into the valve body in a sliding mode, and a first spring is installed between the moving block and the adjusting plate. A fixed ring is fixed to the outer wall of the valve body, a plurality of strip-shaped grooves are formed in the outer wall of the fixed ring, the fixed ring is sleeved with a rotating sleeve which is movably arranged and can conduct fine adjustment on the movable block, and a T-shaped plate which is arranged in a sliding mode is arranged on the rotating sleeve in a penetrating mode and is connected into the strip-shaped grooves in a sliding mode. Compared with the prior art, the defects that the nut needs to be locked with the help of a tool and looseness exists are overcome, operation is simpler and more convenient, and tools are not needed.
