AI Technical Summary

Technical Problem

The existing fuel pump pressure regulating valve is connected to the hose through a single plug-and-removal connection method during installation, resulting in loose connections easily after the hose is inserted and unplugged many times, causing oil leakage.

Method used

A leak-proof fuel pump pressure regulating valve is designed, and the pipeline connection is carried out using multiple locking mechanisms, including sliding adjustment seats, locking clamps, sealing ropes, air bags and sealing air bags. Through the synergistic action of these components, a stable sealing connection is achieved, and secondary auxiliary tightening is performed when the oil pressure is too high.

Benefits of technology

The stable pipeline connection is achieved through multiple locking mechanisms, ensuring the sealing of the connection, avoiding oil leakage, and improving the safety and connection stability of the fuel pump during use.

Abstract

The invention discloses a leakproof fuel pump pressure regulating valve, and belongs to the technical field of fuel pump pressure regulating valves, the leakproof fuel pump pressure regulating valve comprises a pressure regulating valve body mounted on a fuel pump, an oil inlet pipe is arranged on the outer side of the lower part of the pressure regulating valve body, and an oil discharge pipe is arranged at the lower end of the pressure regulating valve body; a limiting fixing plate is fixedly arranged on the outer side of the oil inlet pipe, a sliding adjusting seat is arranged on the outer side of the limiting fixing plate, a reset spring is connected between the inner wall of the sliding adjusting seat and the limiting fixing plate, and locking clamping blocks are evenly, elastically and rotationally installed on the outer wall of the oil inlet pipe. And a sealing binding rope for fixing an external rubber pipe is connected between the two symmetrically arranged locking clamping blocks. According to the leakproof fuel pump pressure regulating valve, stable pipeline connection can be achieved through multiple locking mechanisms, the sealing performance of the connecting position is effectively guaranteed, secondary auxiliary fastening can be conducted when oil pressure is too high, leakage is avoided when the oil pressure is too high, and the safety of a fuel pump in the using process is improved.
