Embodiment Construction

[0028] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0029] Such as image 3 and Figure 4 As shown, when the 120 valve 5 needs to be tested, the 120 valve 5 is installed on the test clamping panel 7, and the test bench surface 6 is set. There are two exhaust ports 52 at the bottom of the 120 valve 5, respectively for the relief of the valve. The air outlet 521 and the air outlet 522 of the relief handle part, and the air outlet 522 of the relief handle part is located in the relief handle part 51 .

[0030] Such as figure 1 and figure 2 As shown, the noise reduction device of...

Abstract

The invention belongs to the technical field of valve body test beds, and particularly relates to a noise reduction device of a 120 valve test bed. According to the technical scheme, the noise reduction device of the 120 valve test bed comprises a fixing support, a lifting mechanism is installed on the fixing support, the other end of the lifting mechanism is connected with a noise reduction box, the noise reduction box is provided with connectors aligned with two exhaust ports of a 120 valve, and after the noise reduction box is lifted, a relieving handle part of the 120 valve stretches into the noise reduction box from one connector; the test clamping panel is provided with a horizontal cylinder used for pushing a relief handle part of the 120 valve to tilt, and a piston rod of the horizontal cylinder extends into the noise reduction box. The invention provides the noise reduction device for the 120 valve test bed, which does not influence the 120 valve installation space.

Description

technical field [0001] The invention belongs to the technical field of valve body test benches, and in particular relates to a noise reduction device for a 120-valve test bench. Background technique [0002] During the exhaust process of the 120 valve performance test, since 11.6 liters of 600kPa pressure air is discharged to the atmosphere through two holes with a diameter of about 30mm, the noise is large, which affects the comfort of the production test environment. With the continuous improvement of production enterprises and users' requirements for the production test environment, how to effectively reduce the exhaust noise during the 120 valve test process has become particularly important. [0003] When the 120 valve is tested on the test bench, according to the requirements of the test content, after the cylinder pushes the relief valve handle, the pressure air is first discharged from the relief handle, and then exhausted from the relief valve exhaust port. If the ...
