With the rapid development of many industrial fields in the country, industrial automation has slowly replaced the artificial operation system, especially the use of various self -control valves. The electric butterfly valve has its unique structural characteristics and has become one of the types of valve types. The scope of applications is also more extensive. However, in different working conditions, it is especially important to choose different electric butterfly valves. It does not waste costs and saves resources. From the sealing structure of the valve, the electric butterfly valve can be divided into two categories: soft sealing and hard sealing. Where are the differences between them, which one is more advantageous, and how can we distinguish it?
The difference between the electric stable butterfly valve and the electric soft sealing butterfly valve is mainly reflected in performance and structure. These two seals can be added with each other. The two have their own advantages and deficiencies. When choosing, you should analyze your own needs and conditions and conditions, and select the appropriate product. The main differences between the main difference between the electric hard-sealing and the soft-sealing industrial butterfly valve are the following points.
The electric soft sealing butterfly valve is mostly a mid -line structure. The sealing materials are generally fluoroplastic, rubber, resin, etc. It has good corrosion resistance and sealing. Choose different component materials, which can be used for multiple media. Most of the electric stable butterfly valves are single-eccentricity, dual-eccentricity, and three eccentric butterfly valves. Most of the sealing uses stainless steel+hard alloy. Among them, there are no friction transmission between the three eccentric butterfly valves. It has the characteristics of high temperature resistance, abrasion resistance, and good mechanical performance.
Soft seal is used for normal temperature environments, and it can be used for low temperature, normal temperature, high temperature and other environments.
Soft sealing low voltage normally, stable can also be used in high-pressure and other industrial conditions.
Soft sealing butterfly valve sealing performance is better, which can reach zero leakage. The disadvantage is that it is easy to aging, wear, and short service life. The hard -dense butterfly valve can maintain good operation at high pressure and high temperature, more abrasion, good mechanical, long service life, but poor sealing performance.
When the electric butterfly valve is turned on and closed, it is not only saving effort, but also has small current resistance. It is convenient and fast to operate, light weight, low volume, and has a relatively simple structure. Customers can be reasonably selected according to economic conditions and medium conditions, on-site environment, etc., whether it is soft-sealing or a stable butterfly valve.
