Abstract
The utility model provides a kind of hydraulic valve test system, including electric proportional pressure control valve, flowmeter, check valve, pressure sensor and three-position four-way electromagnetic directional valve；Three-position four-way electromagnetic directional valve is connected with electric proportional pressure control valve, flowmeter and check valve successively；Pressure sensor is connected on two oil inlets of three-position four-way electromagnetic directional valve.The utility model need to frequently dismantle fluid pressure line when experiment carries out commutation valve test before solving, and reduce the maloperation of operating personnel, improve operating efficiency, reduce the leakage and waste of hydraulic oil；Meanwhile, security and measuring accuracy all increase.
Description
Technical field
The utility model is related to a kind of hydraulic valve test system.
Background technology
During hydraulic valve is hydraulic system, the element of the pressure of control and regulation liquid stream, liquid measure and flow direction, it is ensured that executive component
It is operated as requested, and hydraulic valve is required for testing hydraulic valve various parameters when dispatching from the factory.
It is existing that frequently dismounting fluid pressure line is needed when testing hydraulic valve, when testing different hydraulic fluid ports, so that
The maloperation of operating personnel is added, the leakage and waste of hydraulic oil is easily caused.
The content of the invention
Goal of the invention of the present utility model is to provide a kind of hydraulic valve test system, mainly solves and operates in the prior art
It is cumbersome, the problems such as inefficiency.
The technical scheme that the utility model solves the above problems：The hydraulic valve test system provided, including electric ratio are overflow
Flow valve, flowmeter, check valve, pressure sensor and three-position four-way electromagnetic directional valve；The three-position four-way electromagnetic directional valve is successively
It is connected with electric proportional pressure control valve, flowmeter and check valve；Divide on two oil inlet pipelines of the three-position four-way electromagnetic directional valve
Pressure sensor is not connected with it.Flowmeter outlet and check valve connection, will not be from flow if occurring maloperation hydraulic oil during test
The outlet of meter returns to entrance and flowmeter is caused to damage.
The snap joint for connecting tested hydraulic valve is connected with the oil inlet of above-mentioned three-position four-way electromagnetic directional valve.
Advantage of the present utility model：
The utility model need to frequently dismantle fluid pressure line when experiment carries out commutation valve test before solving, and reduce operation
The maloperation of personnel, improves operating efficiency, reduces the leakage and waste of hydraulic oil；Meanwhile, security and measuring accuracy are all
Increase.
Brief description of the drawings
Fig. 1 is the utility model solenoid directional control valve test hydraulic schematic diagram；
Fig. 2 is the utility model banked direction control valves test hydraulic schematic diagram.
Reference is detailed as follows：
1- electricity proportional pressure control valves；2- flowmeters；3- check valves；4- three-position four-way electromagnetic directional valves；5- pressure sensors；6-
Snap joint；7- system high pressure oil-outs；8- fuel tanks；9- safety valves；10- is tested hydraulic valve.
Embodiment
The utility model is described in detail with reference to Figure of description：
Hydraulic valve test system as shown in Figure 1, when testing solenoid directional control valve, the high-pressure oil outlet 7 of system
Divide two-way, the oil inlet of hydraulic valve is connect all the way, the oil inlet of safety valve, the T mouths directly oil return of safety valve 9 and hydraulic valve are connect all the way
Case 8.A, B hydraulic fluid port of hydraulic valve are connected by snap joint 6 with A, B mouth of three-position four-way electromagnetic directional valve 4, when to hydraulic valve
When different hydraulic fluid ports carry out loading test, the Y2 magnetic valves of the Y1a or Y1b of three-position four-way electromagnetic directional valve 4 and electric proportional pressure control valve
Obtain electric simultaneously, the hydraulic oil of three-position four-way electromagnetic directional valve 4 enters electric proportional pressure control valve 1, constantly changes electricity proportional pressure control valve 1
Size of current is realized to the electric proportional pressure control valve draining of load test of hydraulic valve through excessively stream so as to change the oil pressure relief of overflow valve
The flow of hydraulic valve can be measured during gauge 2, check valve obtains the test pressure of hydraulic valve from pressure sensor 5.
Hydraulic valve test system as shown in Figure 2, when testing banked direction control valves the high-pressure oil outlet of system directly with it is many
The P mouths connection of road valve.A, B hydraulic fluid port of hydraulic valve are connected by snap joint 6 with A, B mouth of three-position four-way electromagnetic directional valve 4, when
When the different hydraulic fluid ports of hydraulic valve are carried out with loading test, the Y1a or Y1b of three-position four-way electromagnetic directional valve 4 and electric proportional pressure control valve
Y2 magnetic valves simultaneously it is electric, the hydraulic oil of three-position four-way electromagnetic directional valve 4 enters electric proportional pressure control valve, constantly changes electric ratio
The size of current of overflow valve 1 is realized and the electric proportional pressure control valve of load test of hydraulic valve is let out so as to change overflow valve oil pressure relief
The flow of hydraulic valve can be measured when oil is by flowmeter, the test pressure of hydraulic valve is obtained from pressure sensor 5.
The hydraulic valve test system is not limited to the test to above two hydraulic valve, when tested hydraulic valve 10 has multiple hydraulic fluid ports
Need only snap joint 6 need to be installed in each hydraulic fluid port during test, changed respectively with 3-position 4-way electromagnetism by snap joint 6 during experiment
Connected to A, B of valve 4.
