As we all know, ball valves are widely used in chemical, petroleum, metallurgy and other fields. The inner wall of the popular all welded ball valve is extremely smooth. In the process of ball valve conveying medium, the friction between the inner wall of the ball valve and the medium is very small, and the medium can pass unimpeded. However, the operation of all welded ball valve will be affected by some factors. 1、 Influence of sealing materials In actual working conditions, all welded ball valves generally use various gases as media: such as natural gas, gas, gas, chemical industry, heating, heating, etc. the temperature of these media is generally between - 20 ℃ - 150 ℃, and the nominal pressure is PN16-25 pressure. The soft seal can meet the requirements, but the quali

In recent years, with the rapid development of scientific and technological revolution, traditional industries and traditional manufacturing methods are facing great challenges, and the development of many traditional industries is in trouble.

In recent years, the sales volume of liquid ammonia emergency shut-off valve shows the trend of high-speed explosion, and its application scope covers many different fields such as mining, petroleum, chemical industry and so on. The following briefly introduces how to achieve good explosion-proof performance of liquid ammonia emergency shut-off valve: 1、The shell material has the explosion-proof effect of gas explosion pressure Compared with other types of solenoid valves, liquid ammonia emergency shut-off valve has better explosion-proof performance because its shell material has the explosion-proof effect of gas explosion pressure. Most shell materials are made of metal frame and flame retardant and high temperature resistant resin. These two materials play a very impor

   With the higher and higher degree of social and economic development, people have higher and higher requirements for the construction of ecological civilization. It is people's common expectation to realize the green development of all walks of life. If the production equipment is backward and the product R & D ability is weak, it is obviously unrealistic to achieve the goal of green development. In the process of chemical industry development, it is natural to be inseparable from various valves. Traditional metal valves are more obvious in the process of use, that is, poor corrosion resistance, poor durability and prone to "running and dripping" and other problems. These shortcomings not only affect the continuity of chemical equipment work, but also may have an i

Even if the water pump manufacturer uses high-quality raw materials and processes to manufacture the water pump, there will still be some abnormalities in the long-term use of the stainless steel diaphragm pump. Among them, the vibration of water pump is common, and there are many reasons for the vibration of unit and pump house building. Specifically, the following reasons will lead to the vibration of stainless steel diaphragm pump: 1、Electrical reasons The motor is the main device in the stainless steel diaphragm pump unit. If the magnetic force inside the motor is unbalanced and out of balance with other electrical systems, it will cause vibration and noise. For example, when the asynchronous motor is running, the radial alternating magnetic tension of the stator and ro
