Today, let's summarize the advantages of sanitary butterfly valve. Sanitary butterfly valve is a very popular equipment in the market. So what are the advantages of sanitary butterfly valve performance? Here we take a look! The sanitary butterfly valve is a valve used in the production and processing of some food, beverages and other products. The sanitary butterfly valve is mainly different in material from the ordinary butterfly valve, so it has all the excellent performance of the butterfly valve.
Strength performance: The strength performance of a sanitary ball valve refers to the ability of the valve to withstand medium pressure. The valve is a mechanical product that is subjected to internal pressure, so it must have sufficient strength and rigidity to ensure long-term use without rupture or deformation.
Sealing performance: The sealing performance of the valve refers to the ability of each sealing part of the valve to prevent the leakage of the medium, which is an important technical performance index of the valve. There are three sealing parts of the valve: the contact between the opening and closing parts and the two sealing surfaces of the valve seat; the matching place between the packing and the valve stem and the stuffing box, and the connection between the valve body and the bonnet. The leakage in the former part is called internal leakage, which is commonly referred to as lax closure, which will affect the ability of the valve to cut off the medium.
. For shut-off valves, internal leakage is not allowed. The leakage in the latter two places is called external leakage, that is, the medium leaks from the inside of the valve to the outside of the valve. External leakage will cause material loss, pollute the environment, and even cause accidents in severe cases. For flammable, explosive, toxic or radioactive media, leakage is not allowed, so the valve must have reliable sealing performance. Sanitary Diaphragm Valve
Opening and closing speed: The opening and closing speed is expressed by the time required for the valve to complete an opening or closing action. Generally, there are no strict requirements for the opening and closing speed of the valve, but some working conditions have special requirements for the opening and closing speed. Some require rapid opening or closing to prevent accidents, and some require slow closing to prevent water hammer, etc. This should be taken into account when selecting the valve type.
Action sensitivity and reliability: This refers to the sensitivity of the valve to respond to changes in medium parameters. For throttle valves, pressure reducing valves, regulating valves and other valves used to adjust medium parameters, as well as safety valves, steam traps and other valves with specific functions, their functional sensitivity and reliability are very important technical performance indicators.
