Classification and selection of fluorine-lined valves

Fluorine-lined valves, also known as fluorine-lined plastic corrosion-resistant valves, use molding (or inlay) method to place polytetrafluoroethylene resin on the inner wall of the valve pressure-bearing parts or the outer surface of the valve internal parts. (The same method is applicable to all types of valves. (lining of pressure vessels and pipeline accessories), a special corrosion-resistant valve made by taking advantage of its unique performance in resisting highly corrosive media. To put it simply, fluorine-lined valves use lining technology for all places within the valve body that can be reached by the medium.

How does the working principle diagram of a pneumatic butterfly valve work? Answered

Pneumatic butterfly valves are particularly widely used as general-purpose valves. Nowadays, many chemical industries, papermaking, coal mines, petroleum, and medical industries will use valves, especially pneumatic valves, and the number used is relatively large. It is a pneumatic butterfly valve that is used in many industries. Pneumatic pipelines are very common! Especially the use of low-pressure medium pipe diameters is increasing, and the larger the pipe diameters of other valves, the more economical they are.

The difference between electric ball valves and electric butterfly valves: Which one is better? Answered

With the acceleration of the industrialization process, in order to adapt to the needs of the times, valve products are constantly updated in the market. Now the requirements for "environmental protection" and "safety" in the valve market are getting higher and higher. At present, the demand for electric valves is high, mainly because the use of electric valves is more energy-saving and safer and more reliable. Compared with traditional manual valves, solenoid valves can be used faster than ordinary valves, which not only reduces physical labor, but also Greatly improve work efficiency.

What is the variable frequency of electric gate valve? How to control?

There are many forms of valves. The simple one is a certain form of switch. The more complicated one is to control the opening of the electric gate valve baffle through simulation. The essence is to control the angle. This is the servo valve, which must be realized by servo control. It is rare to see the size of the valve controlled by the speed size. Of course, it is not to say that there is no such thing. I have seen it in the chemical fiber plant material system. In this form, the air blower maintains a constant wind pressure, which is equivalent to a positive pressure feed. There is a rotating roller in the middle. When the filling nozzle and the roller open the feeding hole, the material can come down and turn over, but the blockage cannot come down. As long as the motor rotates and there is more material, the feeding speed will be faster. This can be understood as speed control. Electric gate valve.

Working principle diagram of electric ball valve: detailed picture explanation

Electric ball valves are mainly composed of electric actuators and ball valves. The electric ball valve is not only a good product for throttling, cutting off, cutting off, and closing, but also a preferred product for flow regulation systems. It has the characteristics of pressure resistance, temperature resistance, corrosion resistance, small flow resistance, long service life and wide application range.

Illustration of the working principle of pneumatic ball valve: attached with internal structure diagram

The pneumatic ball valve is a 90° rotating ball valve. Under the action of air source pressure, the pneumatic actuator (pneumatic head) pushes the rotating shaft through the piston to drive the valve stem to realize the switching and adjustment of the ball valve. The air pressure of pneumatic ball valves is generally 0.1-1.0MPa, and they are generally equipped with valve positioners, filter pressure reducing valves, solenoid valves, limit switches, pneumatic heads and other components. According to power outage or insufficient air pressure, the action of the pneumatic ball valve returns. Pneumatic ball valves are divided into two categories: single-acting and double-acting ball valves.
