Air Volume Control Valve
產品型號:AVCVS
產品分類:自動化設備/產業機械 / 其他產業機械 / 其他
產品特色
The air volume control valve is unified into four specifications in the blade width, the blade shape is a diamond-shaped double blade, and the blades are softly
The valve body frame of the air volume control valve is cold-rolled with 2 mm galvanized sheet, and is welded with carbon dioxide gas shielding or processed by ordinary Q235 plate; the blade is cold-rolled into corrugated with 1 mm galvanized sheet, and the two pieces are synthesized by spot welding Insert square shaft, or cold press forming of 2mm G235 steel plate, single piece punching insert square shaft or welded round shaft.
產品規格
- Before the air valve is installed in place, it should be checked one by one whether its structure is firm and tight, and the switch operation test should be conducted to check whether it is flexible and reliable; the electric air valve should be tested and tested one by one, and the test records should be made.
- Before the air valve is in place, it must be checked whether its scope of application, installation location, air flow direction and operating surface are correct.
- The opening and closing direction and opening angle of the air valve should be accurately marked on the visible surface.
- The effective distance of the operating surface of the air valve from the wall, roof and other equipment and pipelines should not be less than 200mm, and the air valve should not be installed in the structural layer or hole. The width of the seam around the valve should be greater than 150mm.
- Check whether the size of the flange reserved for connecting the air pipe, the diameter of the drill hole and the hole spacing, the flatness and parallelism of the flange surface, the material and thickness of the gasket, and the connection method of the non-metallic air pipe meet the requirements.
- The horizontality error of the air valve installation is not more than 3%, and the verticality error is not more than 2%. The installation tolerance of the air valve without separate support and hanger controls the accuracy together with the air pipe.
- Installation inspection and test content of electric valve:
– Insulation resistance, grounding resistance, withstand voltage.
– AC / DC working voltage is stable.
– Static and dynamic (maximum differential pressure) power measurement.
– Control and feedback signal test.”
