Hydraulic valve is an automatic element operated with pressure oil, which is
controlled by the pressure oil of the pressure distribution valve,
and is usually used in combination with the electromagnetic
pressure distribution valve, which can be used to remotely control
the on/off of the oil, gas and water pipeline system of the
hydropower station. It is widely used in clamping, control,
lubrication and other oil circuits, and is a key element used to
control the pressure, flow and direction of liquid in hydraulic
transmission. The following is a detailed analysis of the hydraulic
valve:
1. Classification
Hydraulic valves can be classified according to different
classification criteria:
Classification by function:
Flow valves: including throttle valves, speed control valves,
diverter flow collector valves, etc., which are used to control the
flow of liquids.
Pressure valves: including relief valves, pressure reducing valves,
sequential valves, etc., which are used to control the pressure of
liquids.
Directional valves: such as solenoid directional valves, manual
directional valves, check valves, etc., which are used to control
the flow direction and on-off of liquids.
Classified according to control methods: manual valves, electric
control valves, hydraulic control valves
Classified by installation method: plate valve, pipe valve,
stacking valve, threaded cartridge valve, cover valve
Classified by operation mode: manual valve, motorized valve,
electric valve, hydraulic valve, electro-hydraulic valve
2. Specific functions and applications
Check valve: only allow the fluid to be connected in one direction
in the pipeline, and cut off in the reverse direction, which plays
a role in preventing the liquid from flowing back.
Reversing valve: change the on-off relationship between different
pipelines to realize the direction control of the hydraulic system.
Relief valve: It can control the hydraulic system to maintain a
constant state when the set pressure is reached, and is used for
overload protection. When the system pressure rises to a limit that
can cause damage, the valve port opens and overflows, keeping the
system safe.
Pressure reducing valve: It can control the branch circuit to
obtain a stable pressure lower than the oil pressure of the main
circuit, and can be divided into fixed value pressure reducing
valve, differential pressure reducing valve and fixed ratio
pressure reducing valve according to the different control pressure
functions.
Sequential valve: After one actuator (such as hydraulic cylinder,
hydraulic motor, etc.) is acted, other actuators are operated in
order.
3. the main points of the design
When designing hydraulic valves, it is necessary to fully consider
their functional requirements, ease of installation, ease of
maintenance and service life. For example, the length, width and
height of the hydraulic valve group are generally determined with
reference to the size of the parts that make up the hydraulic valve
group, and the channel design should ensure that the length is
appropriate and the rotation angle is less to reduce the loss of
oil pressure and heat.
