When the overflow valve is in use, common faults include noise, vibration, radial clamping of the valve core, and pressure regulation failure. This article shares common failure causes and troubleshooting methods of overflow valves.The noise-prone components in hydraulic devices are generally considered to be pumps and valves, and the valves are mainly overflow valves and electromagnetic reversing valves. There are many factors that cause noise.

This article shares common failure causes and troubleshooting methods of overflow valves.The noise-prone components in hydraulic devices are generally considered to be pumps and valves, and the valves are mainly overflow valves and electromagnetic reversing valves. There are many factors that cause noise. The noise of the overflow valve has two types: velocity sound and mechanical sound.

Types and working principle of hydraulic hose joints，1. Hose joint 2. Nut 3. Steel pipe 4. Sleeve, when nut 2 is screwed with the external thread of the joint body (piece 1), as the tightening torque increases, the outer cone of the hose joint and the steel pipe ( Part 3) The inner cone surfaces are in contact and pressed tightly, and the hose connector 1 and 3 cone surfaces are in full contact and produce greater pressure, which plays a sealing role. Due to the leverage of the cone surfaces, the pressure between the cone surfaces is greater.
