Abstract

The invention discloses a micro solenoid valve test fixture, comprising a control mechanism and a pressing mechanism, wherein the control mechanism comprises a test valve block, and the test valve block is provided with a cavity for clamping a micro solenoid valve and an oil matched with the micro solenoid valve. The pressing mechanism includes a sleeve, a movable rod, a pressing cylinder, and a pressing nut, the sleeve is hollow cylindrical, the pressing cylinder is arranged in the hollow cavity of the sleeve, and the middle of the sleeve is radially symmetrical with two long The movable rod passes through the two elongated through holes of the sleeve and is connected to the pressure cylinder. The movable rod controls the pressure cylinder to move up and down in the sleeve. The upper end of the pressure cylinder is provided with a compression nut, and the lower end of the pressure cylinder is for clamping The cavity of the miniature solenoid valve; when the miniature solenoid valve is clamped, the lower part of the pressure cylinder of the press-fitting mechanism is inserted into the test valve block of the control mechanism. The test fixture of the invention can solve the defects of the original test fixture, and has the advantages of wide application range, strong interchangeability and high safety factor.

Description

technical field [0001] The invention belongs to the technical field of solenoid valve testing, and relates to a test fixture for detecting various test performance indicators of a miniature solenoid valve, in particular to a miniature solenoid valve test fixture. Background technique [0002] As an important control component of the fuel regulation system, the micro solenoid valve has the advantages of small size, light weight and large flow rate. At present, it has been widely used in aviation, ships and some special fields. Due to its high pressure (maximum pressure is 31.5MPa), small size (sealing surface is only Φ4.7mm×9.7mm), light weight (less than 100g), and large flow (not less than 0.6L / min at 1MPa) The assembly and testing of the valve presents great difficulties. [0003] The miniature solenoid valve test fixture under the prior art is as attached figure 1 As shown in the figure, it is mainly composed of a test valve block and a sealing bushing. Its working pri...
