Description
Technical field
The utility model relates to a kind of solenoid valve open and shut characteristic non-cpntact measurement device, can be used for solenoid valve, the especially measurement of attitude control engine solenoid valve open and shut characteristic under whole bullet, arrow state.
Background technology
Solenoid valve is one of critical component in the space flight propulsion system, is mainly used in the propellant control module, and its reliability is directly connected to the success or failure of whole bullet, arrow emission.Because the importance of solenoid valve status, preceding, complete machine or whole arrow state all need carry out performance test to it dispatching from the factory.No matter the test of solenoid valve before whole arrow state or emission is taked the current curve method or is utilized the break-make on gas, liquid road to judge, all is subjected to the condition restriction of general assembly factory building or launching tower, must adopt contactless detection method.The problem that the non-contact detecting mode must solve at present is: the one, and the design problem of magnetic sensor must be taken into account high sensitivity and the ability of resisting other magnetic interference preferably; The 2nd, the installation of measurement mechanism, fixation problem, necessary demolition, installation are convenient, satisfy the condition restriction of general assembly factory building.
Summary of the invention
The utility model purpose provides a kind of solenoid valve open and shut characteristic non-cpntact measurement device, overcome the deficiency of existing measuring technology, the variation of stray field around when utilizing the high sensitivity magnetic sensor to measure the solenoid valve action, be equipped with necessary testing circuit, and adopt and to be easy to the airbag aeration fixed form of demolition, installation, thereby reach the purpose of non-cpntact measurement.
Technical solution of the present utility model is:
A kind of solenoid valve open and shut characteristic non-cpntact measurement device, its special character is: comprise upper bracket 1, lower carriage 10, respectively and the annular air-pocket 3 that is tightly connected of upper bracket and lower carriage, be arranged between upper bracket and the lower carriage and be fixed in erecting frame 9 on the upper bracket, be fixed on testing circuit plate 4 on the erecting frame, be installed in magnetic sensor 2 and testing circuit on the testing circuit plate 4, described magnetic sensor is connected with testing circuit, the socket 5 that described lower carriage is provided with charge/discharge gas hole 6 and is connected with testing circuit.
Above-mentioned magnetic sensor 2 comprises the coil rack 7 that is connected with testing circuit plate 4 and is embedded in coil 8 in the coil rack 7.
Above-mentioned air bag lateral surface is provided with non-slip process 11.
Above-mentioned coil rack is a flat high magnetic permeability magnetically soft alloy coil rack.
The advantage that the utility model had:
1, the utility model magnetic sensor magnetosensitive sense direction is consistent with solenoid valve leakage field direction, and is only responsive to the stray field of this direction; Air bag is convenient to non-cpntact measurement Unit Installation, dismounting, for the magnetic sensor operate as normal provides necessary measuring distance.
2, the utility model coil rack is the high magnetic permeability magnetically soft alloy, is flat, and purpose is to enlarge the leakage field collection surface, only to the magnetic-field-sensitive degree maximum of specific direction, reduces the interference in other direction magnetic fields when strengthening magnetic sensitivity.During the solenoid valve action, stray field is caught by magnetic sensor, and coil inside is passed through in " boundling " effect of coils skeleton.Through electromagnetic induction, magnetic sensor coil output one voltage signal that is directly proportional with the line solenoid valve loop current.
3, the utility model is simple in structure, the reliability height; Can realize the non-contact measurement of solenoid valve open and shut characteristic, and the magnetic sensor high sensitivity, antijamming capability is stronger, and detection range is far away; Installation, convenient disassembly have overcome the limitation that whole bullet state solenoid valve detects.Under the situation that does not increase test point on the arrow, solenoid valve open and shut characteristic non-cpntact measurement device provides a kind of brand-new thinking for the affirmation of the solenoid valve state under the whole arrow state.

Embodiment
As shown in Figure 1, be solenoid valve open and shut characteristic non-cpntact measurement device of the present utility model, citation form promptly of the present utility model.It by upper bracket 1, magnetic sensor 2, air bag 3, testing circuit plate 4, socket 5, fill/vent port 6, lower carriage 10 etc. forms.Magnetic sensor 2 is connected on the testing circuit plate 4 by screw, and testing circuit plate 4 is installed on the upper bracket 1 by erecting frame 9, air bag 3 respectively with upper bracket 1 and the lower carriage 10 bonding airtight containers that become.Being connected to of electric signal: the electric connection contact pin on teflon lead connection detection circuit plate 4 and the socket 5, realize the input and output of electric signal.
Magnetic sensor is made up of high permeability coil rack 7, coil 8.Be fixed on the testing circuit plate.With current capacity seemingly, the magnetic line of force is always walked the path of magnetic resistance minimum (magnetic permeability maximum).During the solenoid valve action, stray field is caught by magnetic sensor, and coil inside is passed through in " boundling " effect of coils skeleton.By electromagnetic induction, magnetic sensor produces a voltage signal, and is directly proportional with the line solenoid valve loop current; Handle through subsequent conditioning circuit, can finish non-cpntact measurement the solenoid valve open and shut characteristic.
As shown in Figures 2 and 3, by fill/6 pairs of air bags of vent port inflate, air bag expands, then measurement mechanism is fixed on the inwall 13 of measured body by air pressure, has realized Unit Installation and location, can measure the solenoid valves 12 in the measured body 13.
The ultimate principle of non-cpntact measurement is: during the solenoid valve action, produce a stray field, and by the magnetic sensor coil.
By electromagnetic induction principle:
And
