New type handle throttle without tubing relief valves
Classification of relief valves:
In order to control tank and motor power, speed, direction, and must be configured with a variety of control valve in the hydraulic system, in accordance with the features of different types of valves in the hydraulic system and uses different, can be classified as pressure control valves, flow control valves, directional control valves, pressure control valves can be divided into the overflow valve, unloader valve, pressure relief valve
Relief valve draft picture:
1. valve body 2. seat 3. spool 4. oil pressure gauge port 5. damping hole 6. reset spring 7. pilot valve body 8. remote control ports 9. conical seat 10. taper valve 11. spring 12. Top lever 13. adjustment screw 14. lock nut 15. High pressure oil nozzle
Working principle of pressure relief valves:
When system pressure below spill stream valve of adjustable set value Shi, cone valve close, valve within no oil liquid mobile, A,C two cavity full hydraulic oil, and pressure equal, main valve core is pressure balance State, main valve core by reset spring put bottom of cone pressure tight in main valve valve block Shang, thereby up close a,, b two cavity of role, valve not spill stream, dang system pressure elevated and over regulation value Shi, c cavity of oil through channel put cone valve open, and after main valve core center channel spill stream to b cavity, again returns to tank, Due to through cone valve of oil liquid from Yu a, cavity and after country set of damping hole, so, hole sides produces pressure poor, dang imports (a, cavity) than export (c cavity) of pressure high Shi, liquid pressure up, makes main valve core lift up, valve core Cone and valve block off opened, as long as pilot valve of cone valve opened, main valve core also on opened, System (a, cavity) of pressure by cone valve of spring and pressure to control.
Overflow valve:
1.Limit the system's maximum pressure so that it does not exceed the set pressure of the relief valve value, safety protection.
2. automatically keep system pressure constant, spill stream valve, quantitative pump supply throttle valve adjustable speed system work flow Hou extra of flow spill stream will tank, and in spill stream of while keep pump export Department of pressure for spill stream valve of adjustable set value
3. remote control adjustable pressure, if big flow of spill stream valve is loaded in main pipeline away from tank recently of place, II away from manipulation Taiwan and more far, available loaded in manipulation stage of remote adjustable pressure valve control main spill stream valve to regulation system pressure.
4. unloading, remote control relief valve plug removed and tubing back into the fuel tank and pipes plus a relay controlled by stress in the middle of two way normally closed solenoid valve.
Overflow valve malfunctions and maintenance methods:
| Condition | Fault | Solution and maintenance methods |
| 1.Pressure is too high or too low | 1. Pressure set incorrectly 2. stress disorder 3. carry on the valve is not properly 4. adverse balance piston 5. spring force is too low 6. Valve seat, balance piston, worn or there is dust | 1. correct setting 2. check pressure gauge 3. Remove valve reorganization or Exchange valve, remove the adjustment bolt, 4. tapping valve several times 5. Remove upper cover jiecha valve core dust and other debris blocking the holes of 6. Replace spring 6. cleaning or updates |
| 2. Pressure not settled | 1. balance piston action bad 2. mention moving valve not settled 3. mention moving valve exception 4. oil in the has air 5. mention moving valve block has dust processing | 1. check valve core of hole whether has dust, valve core of action whether sleek, and the spring of State 2. replaced mention moving valve, check oil whether dirty 3. excluded air |
| 3.Tiny vibrations, (ill an abnormal sound when) | 1. Valve anomalies 2. drain air 3. resonance control valve 4. adverse fuel tank tubing 5. flow rate too high 6. outlet there is back pressure | 1. replace the actuator 2. check hydraulic oil pollution 3. displace air |
