Description
Technical field
The invention belongs to hydraulic-driven field, be related to can simultaneously to multiple solenoid valves carry out reliability test device and its
Detection method.
Background technique
The time that solenoid valve reliability test usually requires is longer, and efficiency is lower if being tested one by one, existing
Solenoid valve reliability test usually pass through several solenoid valve serial or parallel connections while being tested to improve efficiency, for
The scheme of solenoid valve parallel connection, due to having several fluid power channel conductives, hydraulic fluid flow rate needed for system simultaneously when solenoid valve is opened
When being several times as much as a solenoid valve and be tested, it is necessary to the hydraulic station for selecting flow deliverability big, otherwise it cannot be guaranteed that
Each solenoid valve has the flow for meeting test requirements document when unlatching, will increase cost and the big usual body of hydraulic station of flow in this way
Product is also big, so as to cause the increase of entire experimental rig volume；And the concatenated scheme of solenoid valve, it cannot be guaranteed that each solenoid valve is opened
The pressure at preceding both ends is equal to test pressure.
Chinese patent CN201420484977.0 discloses a kind of proportion magnetic valve endurance quality test as shown in Fig. 1
Multiple electromagnetism valve bases (2), each electromagnetism valve base (2) is arranged on the test device bracket (1) of the test device in device
Be connected to fuel tank (4) by pipeline respectively, multiple solenoid valves (8) to be measured are moved with can control solenoid valve to be measured (8) and be opened and closed respectively
The PWM signal generator (6) of work connects, and multiple solenoid valves (8) to be measured are configured to be installed on multiple electromagnetism valve bases respectively
(2) structure on, the test device can fast be accurately finished the test of proportion magnetic valve endurance quality, and test result is quasi-
It is really reliable.Meanwhile whether working properly the device can judge solenoid valve, to judge to solenoid valve to be measured self-test one by one
Valve endurance life；The test device can carry multiple solenoid valves simultaneously and be tested, and compatibility is strong.
Hydraulic station will give multiple solenoid valve fuel feeding to be measured, system simultaneously when the scheme of the patent has the disadvantage in that test
When required hydraulic fluid flow rate is tested much larger than a solenoid valve, it is necessary to select big hydraulic of flow deliverability
It stands, otherwise it cannot be guaranteed that each solenoid valve has the flow for meeting test requirements document when opening, will increase cost and flow in this way

Oil pressure, the A mouth of tested valve II communicated by the B mouth of control valve, S mouthfuls with fuel tank, and hydraulic at this is equal to tank pressure, so
Pressure difference before opening between the P mouth of tested valve II and A mouthfuls is equal to test pressure；Hydraulic oil passes through tested valve II during stage C
P mouth, A mouthfuls, the B mouth of control valve, P mouthfuls, the P mouth of tested valve IV, A mouthfuls of inflow fuel tanks, the hydraulic fluid flow rate of whole system do not surpass
The maximum stream flow of a tested valve is crossed, two tested valves of opening have the flow for meeting test requirements document to flow through；
(4) stage D opens tested valve II, tested valve III and control valve, closes tested valve I, tested valve IV,
Hydraulic oil at the A mouth of tested valve IV directly flows back to fuel tank；Hydraulic oil passes through the P mouth of tested valve II, A mouthfuls, control
The B mouth of valve, P mouthfuls, the P mouth of tested valve III, A mouthfuls of inflow fuel tanks；
During entering stage D by stage C: tested valve IV is closed, and the hydraulic oil at the A mouth of tested valve IV directly flows back to
Fuel tank；Tested valve III is opened, and the hydraulic oil to come when being in stage C before opening from tested valve II, control valve can be in tested valve
The pressure that size is equal to hydraulic power source oil pressure is formed at III P mouth, the A mouth pressure of tested valve III is equal to tank pressure, so opening
Pressure difference between the P mouth of preceding tested valve II and A mouthfuls is equal to test pressure；Hydraulic oil passes through the P of tested valve II during stage D
Mouth, A mouthfuls, the B mouth of control valve, P mouthfuls, the P mouth of tested valve III, A mouthfuls of inflow fuel tanks；The hydraulic fluid flow rate of whole system is no more than one
Two tested valves of the maximum stream flow of a tested valve, opening have the flow for meeting test requirements document to flow through.
As shown in figure 4, simultaneously multiple solenoid valves can be carried out with the device of reliability test, including hydraulic station, control valve, hold
Row device and solenoid valve to be measured, solenoid valve to be measured are reversal valve, and the control valve for testing solenoid valve to be measured is also reversal valve, commutation
Valve has P mouthfuls, T mouthfuls and three hydraulic interfaces of A mouth, has opening, closes two states, communicates with A mouthfuls for its P mouthful when opening, other
It is not communicated between mouthful, communicates for its T mouthful and A mouthfuls when closing, be not communicated between other mouths, the upper limit of the number of solenoid valve to be measured is four
It is a, including tested valve I, tested valve II, tested valve III and tested valve IV；Actuator is the actuator of single-acting, the packet of actuator
Include actuator I, actuator II, actuator III and actuator IV；The P mouth of tested valve I, tested valve II P mouth respectively with hydraulic station
