Embodiment 1

[0038] Such as Figure 1-7 As shown, according to a kind of portable vacuum gate valve testing system of the present invention, this embodiment is realized by the design form that all components are integrated in the portable adjustable box 100, are portable adjustable box 100, power supply 200, The cycle control component 300, the sensor component 400 and the test cover 500, the object to be tested is a pneumatic vacuum flapper valve 600, and its driving element is a pneumatic cylinder 601. The cycle control component 300 controls the vacuum by controlling the solenoid valve 602 of the pneumatic cylinder 601. The switch of the gate valve 600. The vacuum gate valve has two flanges, the sealing surface flange 603 and the base flange 604. The test cover 500 is connected to the base flange 604 . Wherein, through the flange 603 on the sealing surface, the switching status of the vacuum gate valve 600 can be observed.

[0039] Figure 1~3 The above is a schematic diagram of the...

Embodiment 2

[0046] Figure 8 It is a schematic diagram of the system composition of the second embodiment. In the second embodiment, the vacuum gate valve 600 under test adopts the form of electric drive, and the electric cylinder 601' is used as the power drive element, and the operation of the electric cylinder 601' is realized by the motor 602'. According to the portable vacuum gate valve testing system of the present invention, in this embodiment, the power supply, cycle control components and the driver of the measured object are integrated in an external control box 300', which is independent of the portable adjustable box 100', The sensor assembly 400 is installed inside the portable adjustable case 100'.

[0047] In this embodiment, the external control box 300' has the functions of timing, counting and alarming, and controls the stroke and test of the electric cylinder through the motor control signal sent out at regular intervals, and then drives the motor 602' to control the s...

Abstract

The invention relates to a vacuum plugboard valve testing device in the technical field of valve testing. The testing device comprises a box body, a power supply assembly, a circulation control assembly and a testing cover plate. The power supply assembly is installed inside or outside the box body and is used for providing a power supply; and the circulation control assembly installed in the boxbody includes a control subsystem. An adjustable fixing mechanism is arranged in the box body and is adjusted and fixed according to enveloping sizes of to-be-tested vacuum plugboard valves with different calibers. The testing cover plate is connected with a valve body of a to-be-tested vacuum plugboard valve in a matching manner. The control subsystem is connected with and controls the to-be-tested vacuum plugboard valve. According to the invention, the position and size of the fixing frame are adjusted to realize three-degree-of-freedom changes of the fixing frame in the box body by combining the box body with the fixing frame. The testing device is suitable for vacuum plugboard valves with different calibers to fix and protect the vacuum plugboard valves.

Description

technical field [0001] The invention relates to the technical field of valve testing, in particular to a vacuum plug valve testing device. Background technique [0002] Vacuum valve testing is one of the important means to test the performance and reliability of vacuum valves, especially when developing new valves or testing product reliability, vacuum valve testing is an important link to verify product quality. Common tests for general vacuum valves include leak rate test and switch test. The leak rate test checks the basic performance of the vacuum valve, and the switch test checks the reliability of the vacuum valve after multiple switches. Typically during switch testing, a leak rate test is also performed at each stage. [0003] During the detection process, it is usually necessary to use leak detectors, gas sources, power supplies and other related equipment and accessories. Depending on the requirements of the test, it may be necessary to add other equipment, whic...
