The body material of the pneumatic butterfly valve of the fan is spherical cast iron. Special structure design, height can be adjusted according to actual needs.
Light and solid shape, easy installation; It is applicable to valve devices in various machines. All ball valves are subject to heat treatment, ED rust release, paint baking or plastic spraying procedures. The load deflection of 25mm and 30mm can effectively eliminate the vibration of mechanical structure.
Fan vibration isolation is generally adopted
Ball valve pneumatic butterfly valve, pneumatic butterfly valve and air cushion pneumatic butterfly valve are used for vibration isolation. The performance of these three pneumatic butterfly valves. In terms of cost, the price of air cushion pneumatic butterfly valve is the highest, followed by ball valve pneumatic butterfly valve, and pneumatic butterfly valve is the cheapest; In terms of valve performance, the valve effect of air cushion pneumatic butterfly valve is the best, followed by ball valve pneumatic butterfly valve, and pneumatic butterfly valve is the worst; In terms of service life, the combined service life of ball valve and pneumatic butterfly valve is the longest, up to 15-20 years; Air cushion pneumatic butterfly valve takes the second place; The pneumatic butterfly valve is the worst, depending on the materials used by the manufacturers, the use environment of the pneumatic butterfly valve is different. In terms of the ease of maintenance, the pneumatic butterfly valve of the ball valve almost needs no maintenance within its service life, and the air cushion pneumatic butterfly valve generally needs one to two years to replenish air; The pneumatic butterfly valve does not need maintenance within its service life. In general, it is more appropriate to use ball valve for pneumatic butterfly valve of fan with high cost performance ratio.
Fans are used in metallurgy, petrochemical, electric power, urban rail transit, textile, shipbuilding and other fields of national economy as well as ventilation in various places. In addition to the traditional application fields, there will still be great development prospects in more than 20 potential market fields, such as comprehensive utilization of coal gangue, new dry process clinker technology, energy saving in metallurgical industry and comprehensive utilization of resources. In the process of growing demand for wind turbines,
As a new auxiliary equipment, pneumatic butterfly valve of fan is favored by many enterprises. As the competition in the wind turbine manufacturing industry continues to intensify, mergers and acquisitions and capital operations among large wind turbine manufacturing enterprises are becoming increasingly frequent. Domestic outstanding wind turbine manufacturing enterprises are increasingly paying attention to the research of the industry market, especially the in-depth research of the industry development environment and product buyers. Because of this, the fan pneumatic butterfly valve has set off large-scale innovation and development in the market. Shanghai Dongfeng Pump Valve Factory has introduced foreign advanced pneumatic butterfly valves to inject powerful power into the domestic market.
