Hydraulic relief valve FOR LONKING WHEEL LOADER

Hydraulic relief valve FOR LONKING WHEEL LOADER/Hydraulic Relief Valve FOR XCMG/Hydraulic Relief Valve FOR Liugong/Hydraulic Relief Valve for Wheel Loader
Loader Hydraulic components are divided into the following parts:hydraulic gear pump、loader multi way valve、Loader variable speed pump、loader pilot valve、Loader full hydraulic steering gear、Flow amplification valve、Variable speed control valve、Loader hydraulic cylinder、Hydraulic oil filter、Screw-in, cartridge-style Hydraulic relief valve、Flow amplification valve、Loader pressure reducing valve、Loader hydraulic cylinder、loader steering control valve
The main parameter of the safety valve is displacement, which is determined by the caliber of the valve seat and the opening height of the valve, by the opening height is different, and divided into micro and full type two. SDLG, Liugong, Yutong, Lonking, XCMG and other wheel loaders, fully open type means that the opening height of the valve disc is 1/4 of the throat diameter of the valve seat. At present, the mass production of safety valve has two categories: spring type and rod type. In addition, there are impulse hydraulic valve, pilot safety valve, safety switch valve, safety decompression valve, static weight safety valve and so on. Spring type safety valve mainly rely on the spring force and work, spring type safety valve and closed and not closed, generally flammable, explosive or toxic medium should choose closed, steam or inert gas can choose not closed, in the spring type safety valve with wrench and without wrench. The role of wrench is mainly to check the flexibility of the valve disc, sometimes can also be used as manual emergency pressure relief, lever safety valve mainly rely on lever hammer force and work, but because of the large size of the lever safety valve often limit the scope of selection. Safety valve with radiator is used when the temperature is higher. Selection of safety valve is determined by the operating pressure of the relief valve nominal pressure, use temperature range is determined by the operating temperature of the relief valve, relief valve set pressure value calculated by spring or leverage constant pressure range, and then determined according to the working medium of the relief valve material and structure, according to the throat area of relief valve discharge volume to calculate the relief valve. The following are the general rules for the selection of hydraulic safety valves. Working principle and structure: safety valve plays a role of safety protection in the system. When the system pressure exceeds the specified value, the safety valve opens, will be part of the system of gas into the atmosphere, so that the system pressure does not exceed the allowable value, so as to ensure that the system is not due to high pressure and accidents. Relief valve is also known as relief valve. Several typical structures of safety valves. Piston type safety valve, the spool is a plate. The air source pressure on the piston A, when the pressure exceeds the safety value determined by the spring force, the piston A is pushed open, part of the compressed air is discharged into the atmosphere from the valve port; When the air pressure falls below the safe value, the spring drives the piston down and closes the valve.
