Abstract
The utility model provides a universal test interface for hydraulic system, which is characterized in that an oil line is provided between an oil inlet and an oil outlet; upper part of the valve housing is provided with a fast pressure test interface and a large flow hydraulic fast interface; center of a rotary core positioned in the valve housing has a through hole, the diameter of which is equal to that of the oil line. The through hole is provided with an oil hole communicating with the fast pressure test interface, which may be arranged in pipeline of the hydraulic system and which has a plurality of standard specifications with various flow ranges and is provided with a plurality of fast interfaces of various specifications to external test instruments for simple tests and precise tests. The utility model makes the hydraulic system tests particularly simple and fast and also makes the universal meter of hydraulic system worthy of the name.
Description
Technical field
The utility model relates to a kind of device that detects hydraulic system.
Background technique
Compare with circuitry, hydraulic system and circuitry have many general character, but aspect the detection diagnosis, circuitry and hydraulic system but have very big difference.Though electricity be cannot see, impalpable material,, till now, the diagnostic detection instrument of circuitry is numerous, and test is got up easy and simple to handle, simply, with the multimeter world of just can walking.
Though the fluid in the hydraulic system is visible material, but the detection of hydraulic system diagnosis is very complicated, just takes simple Pressure testing to go ahead, and most domestic hydraulic equipment does not all have the Pressure testing interface, pressure gauge is connecting system easily, necessary working joint, and different machine dimensions differences, so, detect once pretty troublesome, though what have has a special-purpose screw plug, the interface specification difference must be processed crossover sub.The hydraulic system that has has the pressure measurement fast interface, and pressure measurement is more convenient, but can only do easily-testing.
Precision measurement is used for hydraulic system is adjusted, status monitoring, fault diagnosis etc., detected multi-parameter, as pressure, temperature, flow, power etc., and this type of hydraulic tester arranged on the market, portable, volume is little, in light weight, the precision height, it can survey several parameters simultaneously, so, be called the hydraulic system multimeter again, but, when detecting, the somewhere hydraulic pipe line be taken apart, instrument be sealed in, but each pipe interface Dimensions of various machines is different, during measurement, process different joints and test hose, and easily cause systemic contamination.So detecting once is suitable complexity trouble, measures once sometimes, needs prepare several days, so such multimeter is often put by the height of bundle, can't promote the use of.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, and a kind of hydraulic system general-purpose test interface is provided, and this interface can be installed in the pipeline of hydraulic system, makes the hydraulic system test simple, quick, and easy for installation, maintenance and repair are also very convenient.
The technological scheme that realizes the utility model purpose is a kind of hydraulic system general-purpose test interface, it is characterized in that filler opening being arranged at valve casing one end, the other end has oil outlet, between filler opening and oil outlet, be provided with oil duct, quick pressure measurement interface and high-volume hydraulic rapid pipe joint are housed on valve casing top, rotary plate is installed in valve casing, central authorities have through hole at rotary plate, the diameter of through hole and the equal diameters of oil duct, having oilhole on through hole communicates with quick pressure measurement interface, the rotary plate bottom is fixed with back-up ring and valve casing, and the high pressure seal sealing is arranged between rotary plate and valve casing.
This interface can be installed in the pipeline of hydraulic system, according to different range of flows, several standard sizes is arranged, and, with external test instrument the rapid pipe joint of several specifications is arranged, can be used for doing easily-testing and precision measurement.Make and do the hydraulic system test just especially simply, fast, make the hydraulic system multimeter can really accomplish " general-purpose ".

Embodiment
As shown in Figure 1, when the hydraulic system proper functioning, fluid flows to oil outlet 2 from filler opening 1 through the through hole the rotary plate 4, at this moment, has fluid to lead to quick pressure measurement interface 9 from oilhole 8, can pressure measurement on this interface, thermometric, sampling, rotary plate 4 bottoms are fixing with valve casing 3 with back-up ring 5, and high pressure seal 6 sealings are used in the axial motion of restriction rotary plate 4 between rotary plate 4 and valve casing 3, prevent oil leakage, working principle as shown in Figure 3.
As shown in Figure 2, when test, rotary plate 4 is rotated 90 degree, oil duct 7 is blocked on the two sides in addition of spool 4, will get final product between the testing instrument access 10 and 11 with rapid pipe joint, and little oilhole 8 logical pressure measurement interfaces 9 are arranged.After finishing hydraulic test, spool being returned 90 degree go back to, testing instrument is pulled up from 10,11 mouthfuls get final product, is high-accuracy the cooperation between rotary plate 4 and the valve casing 3, prevents oil leakage, and working principle as shown in Figure 3.
As shown in Figure 4, the typical case of hydraulic system general-purpose test interface in hydraulic system uses (representing hydraulic system general-purpose test interface with symbol T among the figure)
1, is contained on the oil road of oil hydraulic pump
Diagnosis and monitoring hydraulic pressure pump performance, parameters such as measurement of discharge, pressure, power are come the evaluating liquid press pump, the flow rate pressure song of test or adjustment oil hydraulic pump.
2, be installed between the housing discharging oil duct of oil hydraulic pump and oil hydraulic motor
Detect and monitor oil hydraulic pump and the oily flow of housing discharging of motor, the performance of evaluating liquid press pump and motor accurately under a certain state.
3, be installed in a certain oil duct of oil hydraulic cylinder
Judge the degree of letting out in hydraulic jack whether with interior discharge.
Hydraulic system general-purpose test splice for the adjustment of hydraulic system, detect monitoring, fault diagnosis general, easy a, platform fast be provided, can be used as a standard configuration element and be installed in the hydraulic system, for Maintenance of Hydraulic System and repairing provide great convenience.
