Problems solved by technology

[0006] Aiming at the above-mentioned defects in the prior art, the present invention provides a dual-station rollover valve synchronous test device, which solves the problem that the existing rollover valve detection uses only a single testing device, which can only test a certain performance of the rollover valve. At the same time, the original performance measurement of the dump valve also included the judgment of some personnel, the test time is long, the detection efficiency is low, and the accuracy of the data is also low.

Embodiment 1

[0026] A kind of synchronous test device for double-station rollover valve in the embodiment of the present invention, such as figure 1 and figure 2 As shown, it includes: mechanical transmission part, pneumatic part, console and dump valve 2. The mechanical transmission part includes workbench 3, servo motor 4, reduction box 5 and valve tooling 6. The servo motor 4 transfers the rotational torque through the reduction box 5 Transfer to the valve tooling 6, the workbench 3 is used to fix and support the servo motor 4, the reduction box 5 and the valve tooling 6, after the reduction box 5 is fixed on the workbench 3, the servo motor 4 and the reduction box 5 are installed in cooperation with each other , so that the rotational movement of the servo motor 4 is transmitted to the rotating shaft between the reduction box 5 and the valve tooling 6 through the reduction box 5, thereby driving the valve tooling 6 to rotate, realizing the simulation of the use state of the tipping va...

Embodiment 2

[0034] Compared with Example 1, the double-station rollover valve 2 synchronous test device in Example 2 also includes a leak tester, specifically, a long air pipe is used to pass through the valve tooling 6 and connect the rollover valve 2 through the leak tester , after the pressure is adjusted, keep the required time for judging whether the test requirements are met. In the actual application process, by comparing the test standards, it can accurately judge whether the tipping valve 2 meets the requirements.

Embodiment 3

[0036] Compared with Embodiment 1, the liquid level measurement part in Embodiment 3 includes a stepping motor and a liquid level detection manipulator, the stepping motor makes the liquid level detection manipulator move up and down, and the liquid level detection manipulator is provided with a photoelectric sensor, through steps The motor pulse positioning and the photoelectric sensor detect the height of the oil level in the valve tooling 6. This design is more accurate and reliable; the performance of the tipper valve 2 can be obtained in more detail by conducting the test of the tipper valve 2 at different oil level heights. The parameter can make the rollover valve 2 have higher safety performance in the application process of the vehicle.

[0037] The photoelectric sensor is also used to send on-off signals, record flow, pressure and height information in real time, and provide an external trigger signal when the console receives an alarm, so as to realize real-time moni...

Abstract

The invention discloses a double-position synchronous testing device for a rollover valve, and relates to the field of automobile fuel system testing devices. The device comprises mechanical transmission parts, a pneumatic part, a console and the rollover valve. Each mechanical transmission part includes a workbench frame, a servo motor, a reduction gearbox and a valve tool, wherein the servo motor transmits a rotational torque to the valve tool through the reduction gearbox, and the workbench frame is used for fixedly supporting the servo motor, the reduction gearbox and the valve tool. Eachvalve tool is also provided with a press-fit sealing device. The pneumatic part includes an air source component, multiple ventilation paths and a switching valve. The gas in the air source componentsequentially passes through the ventilation paths and the switching valve. The pneumatic part is also provided with a pressure sensor and a flow sensor. The interior of the valve tool is also providedwith a liquid level measuring part. According to the invention, the device is provided with the two mechanical transmission parts for the synchronous test, and the design of the switching valve at astart part can achieve the detection of the basic performances of the rollover valve. The synchronous test enables the device to have a comparison effect while improving the efficiency.

Description

technical field [0001] The invention relates to the field of automobile fuel system testing devices, in particular to a dual-station rollover valve synchronous testing device. Background technique [0002] With the development of society, automobiles are becoming more and more popular in people's lives, and the safety of automobiles has attracted more and more attention. In the actual operation of automobiles, the ability to deal with dangerous situations is very important, so automobiles There are many devices to ensure the safety of personnel and equipment, and the rollover valve is one of them. Its function is to exhaust and replenish air in the fuel tank, to ensure a constant pressure difference between the inside and outside of the fuel tank, and to prevent the fuel in the fuel tank from flowing in when the vehicle tilts or rolls over. Exhaust pipe to prevent fuel explosion. It can be seen that the reliability of the operation of the rollover valve is absolutely importa...
