Single Acting Hydraulic Cylinder Valve

According to the use of relief valve, pressure reducing valve and sequence valve. ⑴ Relief valve: can control the hydraulic system to maintain a constant state when reaching the setting pressure. Relief valves for overload protection are called safety valves. When the system fails and the pressure rises to the limit value that may cause damage, the valve port will be opened and overflow to ensure the safety of the system. ⑵ Reducing valve: can control the branch circuit to obtain stable pressure lower than the main circuit oil pressure. Reducing valve according to the pressure function it controls is different, and can be divided into fixed value reducing valve (output pressure for constant value), fixed difference reducing valve (input and output pressure difference for fixed value) and fixed ratio reducing valve (input and output pressure to maintain a certain proportion). (3) Sequence valve: can make an executive component (such as hydraulic cylinder, hydraulic motor, etc.) action, and then in order to make other executive components action.

Repair process:

1. Bake the scratched part with oxyacetylene flame (master the temperature and avoid surface annealing), and bake the oil that permeates the metal surface all the year round until there is no spark.

2, the scratched part with Angle grinder surface treatment, grinding depth of more than 1 mm, and along the guide rail grinding groove, preferably dovetail groove. Both ends of the scratch are drilled deeper to change the force situation.

1) Flexible action, reliable function, small impact and vibration, small noise, long service life.
2) When fluid passes through the hydraulic valve, the pressure loss is small; When the valve port is closed, the sealing performance is good, the internal leakage is small, no external leakage.
3) The controlled parameters (pressure or flow) are stable, and the variation is small when subjected to external interference.
4) Compact structure, easy installation, debugging, use, maintenance, good versatility.

Due to the residual compressive stress on the surface, rolling processing helps to close the small cracks on the surface and prevent the expansion of erosion. Therefore, the corrosion resistance of the surface can be improved, and the generation or propagation of fatigue cracks can be delayed, so as to improve the fatigue strength of the cylinder. Through rolling forming, a cold work hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface caused by grinding, thus improving the wear resistance of the cylinder inner wall and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the compatibility.
