Pneumatic butterfly valve, also known as concrete precast hollow slab inflatable core mold, bridge inflatable core membrane, internal mold. It is mainly used for the pouring and forming of highway bridge concrete pre tensioned and post tensioned beams. It is also used in culvert drainage works. The pneumatic butterfly valve is a kind of expandable and contractible internal mold with different shapes, which is vulcanized with high molecular weight and high-strength fiber cloth (it is a product vulcanized with fiber reinforcement layer, with high compressive strength, elasticity and air tightness). After being filled with compressed air, the expansion reaches the design requirements of its section. The inflation pressure is determined according to the manufacturer's logo. The capsule can also be extracted from the cavity. It is easy to use, economical and durable. It is soft and shrinks when not inflated, and can be folded and curled at will. After inflated and expanded, it has sufficient strength to withstand the pressure of concrete. It can replace the original wood mold, bamboo mold and steel mold, and can be reused for many times. It is a supporting product of concrete products that can reduce costs and speed up construction progress.
The existence of pneumatic butterfly valves is only for a few small aspects. This is not good. Compared with pneumatic butterfly valves, will their own use methods or other aspects be different? Let's briefly explain the use of pneumatic butterfly valve.
1. The pneumatic butterfly valve is an inflatable product, which is easy to use and remove after use, saving labor time and cost, and reducing work intensity.
2. The return on investment of the pneumatic butterfly valves produced by our company is high. Each pneumatic butterfly valve can be used repeatedly. The low cost can reach (round pneumatic butterfly valve 80 times), (oval pneumatic butterfly valve 70 times), (octagonal pneumatic butterfly valve 65 times) to save capital investment. Our factory has many years of production experience,
All the pneumatic butterfly valve products have passed 48 hour pressure measurement and side leakage test to ensure product quality, and pay attention to the brand image of the company and pneumatic butterfly valve.
3. All pneumatic butterfly valves adopt the process of natural and synthetic combination to ensure the quality of pneumatic butterfly valves is not disordered. To this end, our company provides high-quality after-sales service, customer return visits, customer technical frustration answers, and even sends technical staff to the customer's construction site for guidance. The pneumatic butterfly valve produced by our company gives buyers no worries.
4. Pneumatic butterfly valve. First, it is aimed at its own existence. The use of pneumatic butterfly valve is very convenient, and it is also important for inflatable products. It is perfect to save labor time and labor cost.
The pneumatic butterfly valve has been proved by many engineering construction practices that the pneumatic butterfly valve hole drawing process equipment is simple, which not only saves materials, but also the pneumatic butterfly valve has a variety of shapes, such as round, oval, rectangular, arch, octagon, trapezoid and other apertures. It can also be made into straight holes and variable cross-section faces (positive and oblique), which can make the building structure become light and thin-walled hollow beams and slabs.
