Description

Technical Field

[0001] This utility model belongs to the technical field of pulse valve test benches, and specifically relates to a pulse valve performance test bench. Background Technology

[0002] A pulse valve is a diaphragm valve that is controlled by a pilot valve such as an electromagnetic or pneumatic valve and can instantly open and close a high-pressure air source to generate a pulse. Pulse valves are a major component of bag filters. Pulse valves rely on the delay effect of airflow through air resistance and air capacity to convert a long input signal into a pulse signal.

[0003] Currently, in the performance testing of pulse valves, the extraction column required for testing can reach a height of 10 meters. Traditional extraction columns are typically one-piece structures, making installation and disassembly inconvenient. Furthermore, pulse valve performance testing benches generally utilize reinforced concrete infrastructure with a height difference of up to 10 meters, resulting in large footprints and high implementation costs. Therefore, a new type of pulse valve performance testing bench is needed to solve these technical problems. Utility Model Content

The air compressor, air tank, pressure regulating valve, pulse valve test bench, and pulse valve are all fixedly installed on a support base plate. A test bench is also provided on the support base plate, and an extraction column is fixedly installed inside the test bench.

[0007] The extraction column includes an extraction column base, which is fixedly installed at the bottom of the test bench. A U-shaped connecting tube is provided below the extraction column base.

[0011] As a preferred embodiment, the extraction column has a diameter of φ300 and a liquid level height of 10m.

[0012] As a preferred embodiment, the stainless steel section of the extraction column is a 1-meter stainless steel pipe, and the PVC section of the extraction column is formed by sequentially splicing three 3-meter PVC pipes.

Therefore, they should not be construed as limitations on this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] Please see Figures 1 to 3As shown, this embodiment of the utility model provides a pulse valve performance test bench, including an air compressor 1, an air tank 2, a pressure regulating valve 3, a pulse valve test bench 4, and a pulse valve 5 connected in sequence.

A test bench 6 is also provided on the supporting base plate, and an extraction column 10 is fixedly installed inside the test bench 6. In this embodiment, the air compressor 1 provides compressed air for the entire device, and the 1m³ air tank 2 is used to provide stable air pressure for the pulse valve 5. The air compressor 1 and air tank 2 form an air supply unit. The pressure regulating valve 3 has DN50 flange interfaces on both sides for easy connection. The pulse valve test bench 4, in conjunction with the structure of the pulse valve 5, secures the pulse valve 5. The test bench 6 is used to fix the DN50 connecting pipe 7, the pulse leg 9, and the extraction column 10, etc. The extraction column 10 includes an extraction column base 8, which is fixedly installed at the bottom of the test bench 6. A U-shaped connecting pipe 16 is disposed below the extraction column base 8. One end of the U-shaped connecting pipe 16 is connected to a pulse leg 9, and the other end is connected to a stainless steel section 14 of the extraction column. A PVC section 15 of the extraction column is fixedly connected to the top of the stainless steel section 14. In this embodiment, the extraction column 10 adopts a detachable structure consisting of the extraction column base 8, the U-shaped connecting pipe 16, the stainless steel section 14, and the PVC section 15. When performing pulse valve performance testing, the extraction column base 8, the U-shaped connecting pipe 16, the stainless steel section 14, and the PVC section 15 are fixedly assembled together, which is convenient to install, relatively low in cost, and easy to disassemble after the performance test is completed.
