Stainless steel butterfly valves are usually metal hard seal butterfly valves, which can be divided into manual, pneumatic and other driving modes. It is suitable for use in pipelines with high temperature and corrosive media. Stainless steel butterfly valves are currently widely used in the market and can be seen in many fields. In particular, it acts as a gas medium regulating flow or shut-off device in dusty cold air or hot air gas pipelines for ventilation and environmental protection projects in metallurgical, chemical, building materials, power stations, glass and other industries.
Stainless steel butterfly valves have the following two characteristics:
First, it is designed and manufactured by adopting a new structure of medium-line disc and short-structure steel plate welding. It is compact in structure, light in weight, easy to install, small in flow resistance, large in circulation, avoiding the influence of high temperature expansion, and easy to operate.
Second, there are no connecting rods, bolts, etc., reliable operation and long service life. It can be installed in multiple stations and is not affected by media flow.
The advantages and disadvantages of stainless steel butterfly valves are:
Advantages: 1. It is easy and quick to open and close, labor saving, small fluid resistance, and can be operated frequently. 2. It is simple in structure, small in size and light in weight. 3. It can transport mud and store the least amount of liquid at the mouth of the pipe. 4. Under low pressure, it can achieve a good seal. 5, it has good regulation performance.
Disadvantages: 1. The pressure and operating temperature range are small. 2. Poor sealing.
In response to these characteristics, we first strictly follow the operating procedures in the manual in the usual operation. Finally, pay attention to observe the valve opening and closing instructions and valve stem operation. The valve opening and closing degree should meet the requirements. During the process of opening and closing the valve, if the signal indicator light is found to be incorrect and the valve has abnormal noise, it should be stopped and checked in time. We pay attention to these problems in daily use, which can reduce the damage caused by the operation error of the stainless steel butterfly valve.
Stainless steel butterfly valves are one of the valve products that many manufacturers need to purchase. When selecting the specific valve parameters such as the model diameter, the customer must pay attention to the choice of the valve manufacturer. Only by selecting a reputable valve manufacturer with superiority can the valve quality be better and the later repair more convenient.
