Electric 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 electric butterfly valve is an expandable and contractible internal mold with different shapes (a product made by vulcanizing with the fiber reinforcement layer, which has high compressive strength, elasticity and air tightness), which is vulcanized from the polymer and high-strength fiber cloth. 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 electric butterfly valve is only for a few small aspects, which is not good. Compared with electric butterfly valve, will its own use method or the existence of other aspects be different? Let's briefly explain the use of electric butterfly valve.
1. The electric 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 electric butterfly valves produced by our company is high. Each electric butterfly valve can be used repeatedly. The low cost can reach (80 times for circular electric butterfly valves), (70 times for oval electric butterfly valves), and (65 times for octagonal electric butterfly valves) to save capital and investment. Our factory has many years of production experience,
All the electric butterfly valve products provided have passed the 48 hour pressure measurement and side leakage test to ensure the product quality and pay attention to the brand image of the company and the electric butterfly valve.
3. All electric butterfly valves adopt the process of natural and synthetic combination to ensure the quality of electric 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 electric butterfly valve produced by our company makes buyers worry free.
4. Electric butterfly valve. First, it is aimed at its own existence. The use of electric butterfly valve is very convenient, and it is also important for inflatable products. It is perfect to save labor time and labor cost.
The electric butterfly valve has been proved by many engineering construction practices that the electric butterfly valve hole drawing process equipment is simple, not only saving materials, but also the electric 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.
