1. It is designed and manufactured by adopting a new structural form of welding of mid-line disc plate and temporary structure steel plate. It has a compact structure, lightweight, easy installation, low flow resistance, large circulation, avoids the influence of high-temperature expansion, and is easy to operate.

7. There are no connecting rods, bolts, etc., so it works reliably and has a long service life. It can be installed in multiple positions and is not affected by the flow of the medium.

(1) The air volume control valve has four specifications when the blade width is all the same. The blade shape is a diamond-shaped double blade, and the blades are soft overlapped, so the sealing performance is excellent.

(2) The valve body frame of the air volume dispatching valve is formed by cold rolling of 2mm galvanized sheet and then welded by maintenance welding of carbon dioxide gas or processed and welded from general Q235 sheet; the blade is cold-rolled with 1mm galvanized sheet into a corrugated shape, two pieces It is composed of spot welding inserting square shaft, or 2mm G235 steel plate cold forming, single-piece punching inserting square shaft or welding round shaft.

(8) The dispatching valve is divided into manual and electric. According to the materials used, it is divided into four types: carbon steel plate, galvanized plate, aluminum alloy plate, and stainless steel plate. The valve body structure and specifications are the same.

(1) The connecting pipe size of the split multi-leaf air volume regulating valve is the same as the rectangular air pipe size stipulated by the national ventilation duct standardization.

(2) The blades of the air volume regulating valve are split-opening and forward-opening, and are used as regulating valves in ventilation, air conditioning, and air purification systems.

(3) Tested and measured, the air-tightness of the air volume regulating valve is good, the relative air leakage is about 9%, and the regulating performance is good.

1. One-time regulating valve: If the system is not balanced, it is a regulating valve designed to achieve the required air volume. It is divided into flapper valve, butterfly valve, multi-leaf regulating valve, and three-way valve.

2. Frequently switched regulating valves: Mainly include fresh air valve, primary and secondary air return valve, exhaust valve (including exhaust valve for comprehensive exhaust and partial exhaust).

5. Automatic control valve: Mainly used for automatic adjustment of fresh air, primary return air, and secondary return air. In addition to meeting the requirements of frequently-on-off regulating valves, it should also have good regulating characteristics.

1. It is designed and manufactured by adopting a new structural form of welding of center-line disc plate and short structure steel plate, compact structure, light weight, easy to install, small flow resistance, large circulation, avoiding the influence of high temperature expansion, and easy to operate

4. There are no connecting rods, bolts, etc. in the air volume regulating valve, which is reliable in operation and long in service life. It can be installed in multiple positions, and is not affected by the flow of the medium. There are no connecting rods, bolts, etc., so it works reliably and has a long service life. It can be installed in multiple positions, and is not affected by the flow of the medium.

(1) The takeover standard of the split multi-leaf air volume dispatching valve is the same as the rectangular air duct standard of the national ventilation duct standardization.

(2) The blades of the air volume dispatching valve are side-opening and forward-opening, which are used as dispatching valves in ventilation, air dispatching and air purification systems.

(3) According to the test, the air-tightness of the air volume dispatching valve is good, and its relative air leakage is about 6%, and the dispatching performance is good.

1.The wind valve material is PP and PVC, which is characterized by anti-corrosion, anti-aging, price concessions, easy installation.

2.The current manual air valve mold a molding, high strength, good sealing, smooth appearance, low resistance. Its specifications are diameter 63mm, 75mm, 90mm, 110mm, 160mm, 200mm, 250mm, 315mmd. The diameter of it is more than 355 can be customized.

4. Made of environmentally friendly materials that can be recycled.

1. It is designed and manufactured by adopting a new structural form of welding of mid-line disc plate and temporary structure steel plate. It has a compact structure, lightweight, easy installation, low flow resistance, large circulation, avoids the influence of high-temperature expansion, and is easy to operate.
