The utility model relates to a rationally, through carrying out the flow test respectively to single booster valve and relief pressure valve, then respectively the option flow error is less than or equal to 1% booster valve, relief pressure valve pair become the electromagnetism valves to the qualified solenoid valve of each group of option gets into pressure regulator's final assembly, has improved the qualification rate of pressure regulator assembly greatly, effectively guarantees that its pressure regulating characteristic of solenoid valve requires unanimous basically in braking process, improves pressure regulator's pressure regulation characteristic and performance.

Description

Pressure governor solenoid valve flow testing device
Technical field
The utility model relates to a kind of anti-blocking brake system of automobile pressure governor solenoid valve flow testing device, belongs to the manufacturing technology field of solenoid valve testing apparatus.
Background technology
Pressure governor is most important parts in anti-blocking brake system of automobile (being called for short ABS) the three big parts, pressure governor is provided with four groups of solenoid valves, every group of solenoid valve formed by pressure charging valve and reduction valve, the quality of its adjusting function directly has influence on the indexs such as braking ability, directional stability, steering capability and minimum braking distance of ABS, therefore requires every group of solenoid valve (pressure charging valve and reduction valve) its voltage adjustment characteristic basically identical in braking procedure when assembling.
The pressure control characteristic of four groups of solenoid valves that existing pressure governor is used in the assembling test process is generally integrated testability, promptly directly four groups of solenoid valves on the pressure governor being carried out the pressure control characteristic measures, show from the family curve of measuring, because the integrated testability randomness is bigger, cause angularity to differ bigger, influence practical effect, reduced the qualification rate of pressure governor simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, can effectively guarantee solenoid valve its voltage adjustment characteristic requirement basically identical in braking procedure, improves the pressure control characteristic of pressure governor and the pressure governor solenoid valve flow testing device of usability.
The utility model is a pressure governor solenoid valve flow testing device, it is characterized in that by the solenoid valve mount pad of bringing oily joint and delivery connection into, place the solenoid valve fixture of band fixed cover on the solenoid valve mount pad, the tensimeter that links to each other with fuel inlet fitting, place formations such as interior butt-end packing pad of solenoid valve mount pad and seal bar, fuel inlet fitting links to each other with the peripheral hardware oil pump station with delivery connection, also is provided with the digital display flowmeter on the delivery connection.
Also can be provided with the O RunddichtringO in the described solenoid valve mount pad.
Also can be provided with the O RunddichtringO on the described seal bar.The bottom of described seal bar also can be provided with the adjustment screw.
The utility model is reasonable in design, by single pressure charging valve and reduction valve are carried out flow rate test respectively, match the pressure charging valve of flow error≤1% then respectively, reduction valve is paired into electromagnetic valve group, on the test suite of solenoid valve pairing test platform, record the conventional brake characteristic of solenoid valve, the single cycle control characteristic, compound control characteristic, the valve regulation characteristic is pressed in increase and decrease, every family curves such as continuous supercharging performance, thereby match the qualified solenoid valve of respectively organizing, enter the general assembly of pressure governor, improve the qualification rate of pressure regulator assembly greatly, guaranteed the quality of product.
Description of drawings
Accompanying drawing is the utility model one-piece construction cut-open view.
Among Fig. 1: 1 is high-pressure oil pipe, and 2 is fuel inlet fitting, and 3 is the solenoid valve mount pad, 4 is tensimeter, and 5 is electromagnetic valve coil, and 6 is the solenoid valve fixture, 7 is fixed cover, 8 is solenoid valve, and 9,11 is the O RunddichtringO, and 10 are the butt-end packing pad, 12 is seal bar, 13 for adjusting screw, and 14 is delivery connection, and 15 is the digital display flowmeter.
Embodiment
The utility model is mainly by the solenoid valve mount pad 3 of bringing oily joint 2, tensimeter 4, delivery connection 14, digital display flowmeter 15 into, place the solenoid valve fixture 6 of band fixed cover 7 on the solenoid valve mount pad 3, place butt-end packing pad 10, O RunddichtringO 9,11, seal bar 12 in the solenoid valve mount pad 3, adjust formation such as screw 13, fuel inlet fitting 2 links to each other with the peripheral hardware oil pump station with delivery connection 14.
During work, tested solenoid valve assembly 8 is packed in the solenoid valve mount pad 3, electromagnetic valve coil 5 is packed in the solenoid valve assembly 8, with solenoid valve fixture 6 and fixed cover 7 tested solenoid valve assembly 8 is fixed in the solenoid valve mount pad 3 respectively then, tighten and adjust screw 13, butt-end packing pad 10 is not leaked with tight contact of solenoid valve assembly 8 ports, start the peripheral hardware oil pump station, the output oil pressure of peripheral hardware oil pump station is adjusted to 10Mpa, connect the operating voltage of solenoid valve assembly 8, solenoid valve assembly 8 has been opened at this moment, by the oil of peripheral hardware oil pump station output through high-pressure oil pipe 1, fuel inlet fitting 2, solenoid valve assembly 8, delivery connection 14, digital display flowmeter 15 forms circulating oil path, and directly read the flow number of solenoid valve under this pressure condition and record number from digital display flowmeter 15.
The solenoid valve that pressure charging valve and the reduction valve by flow error≤1% matched are formed is respectively on solenoid valve pairing test platform, every family curves such as valve regulation characteristic, continuous supercharging performance are pressed in the conventional brake characteristic, single cycle control characteristic, compound control characteristic, the increase and decrease that record solenoid valve, thereby match qualified respectively organize solenoid valve, the general assembly that enters pressure governor.
