This article will take you to understand
wafer butterfly valves from a professional point of view.
Valves belong to one kind of large-scale manufacturing industry. As a main category of valves, its scale can not be underestimated. We all know that in today's technological development and innovation, there are many types of
butterfly valves whether it is petrochemical, energy, metallurgy, power and other industries, we can see it. At present, there are 23 kinds of butterfly valves. It is believed that in the future, with the innovation of science and technology, more vaeirties will be expanded. The product is composed of valve body, valve stem, butterfly plate and sealing ring. It is a simple regulating valve. The valve body is cylindrical with short axial length and built-in butterfly plate. It is suitable for transporting various (non) corrosive fluid medium in LPG, city gas, power generation and environmental protection engineering systems, and it is used to regulate and cut off the flow of medium.
The utility model has the advantages of simple structure, light weight, good fluid control characteristics and sealing performance. Due to the streamline design, the loss of fluid resistance is small, which is a typical energy-saving product. The valve rod has good comprehensive mechanical properties, corrosion resistance and scratch resistance after quenching and tempering treatment. The unique technical system is adopted to greatly shorten the shutdown time.
It is used to regulate the flow rate, the pressure loss in the pipeline is more. When the valve is closed, it has to bear the pressure of the medium in the pipeline, which requires it to have a certain firmness. Because its structure is very suitable for making large diameter valves, the number of large diameter
butterfly valves is still increasing. In the use of
wafer butterfly valves, we can only choose the correct size and type in order to make it work better.
Application ranges:
It is not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power station.
It is used for gas pipeline in sulfuric acid industry: inlet and outlet of blower in front of furnace, inlet and outlet of relay fan, series connection valve of electric mist eliminator, inlet and outlet of S02 main blower, converter regulation, inlet and outlet of preheater, etc.
It is used in the sulfur burning, conversion and dry absorption section of the sulfur burning sulphuric acid plant. It is considered by the majority of users as
a butterfly valve with good sealing performance, light operation, secondary corrosion, high temperature resistance, convenient and flexible operation, safe and reliable use, which has been widely used. The
wafer butterfly valve is also widely used in the pipeline of SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, alkali, sea water, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media in the chemical, petrochemical, smelting, pharmaceutical, food and other industries.
