  • What are the advantages of pneumatic ball valves (1)?

    Compared with other types of valves, pneumatic ball valves have angular stroke output torque, fast opening, stable and reliable, wide application, and the following advantages:1. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.2. Anti-static function: A spring is set between the ball, the valve stem and the valve body, which can export the static electricity generated during the switching process.3. Due...

  • What are the characteristics of ball valve?

    Wear resistance; because the valve core of the hard-sealed ball valve is alloy steel spray-welded, and the sealing ring is alloy steel surfacing, so the hard-sealed ball valve will not produce too much wear when switching. (Its hardness coefficient is 65-70)Second, the sealing performance is good; because the sealing of the hard-sealed ball valve is artificially ground, it cannot be used until the valve core and the sealing ring are completely matched. So his sealing performance is reliable.Thir...

  • Do you know the product of ball valve?

    The ball valve came out in the 1950s. With the rapid development of science and technology, the continuous improvement of production technology and product structure, it has rapidly developed into a major valve type in just 40 years. In developed western countries, the use of ball valves is increasing year by year.In my country, ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal...

  • Do you know what are the classifications of ball valves?

    Function classification:1. Bypass valve: The ball valve is generally opened for still water, so the bypass valve is set to be flat pressure first, that is, the two sides are filled with water;2. Air valve: when filling with water, the buoy will automatically close the valve when the air is removed; when draining, the buoy will drop by itself for supplementing air;3. Pressure relief valve: When opening and closing the valve, remove the pressure water between the valve and the sealing cover, so as...

  • Do you know ball valve?

    Ball valve, the opening and closing member (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control, among which the hard-sealed V-shaped ball valve has a V-shaped ball core and a metal valve seat of hard alloy surfacing.Strong shearing force, especially suitable for media containing fibers, tiny solid particles, etc.The multi-port ball valve on the pipeline can not only flexibly control the confluence, diversion, and ...

  • Types and characteristics of household heating valves

    Heating in winter is mainly based on water heating, whether it is independent heating or central heating; the pipe fittings that control the heating system are still valves, and there are many types of valves, and there are no less than ten of them used in heating systems. Kind of, these are a bit far from our lives, but the valves that are closely related to our lives are the valves of the domestic heating system. Generally speaking, they can be divided into three types, one is the globe valve ...

  • Valve knowledge: valve terms

    1) General purpose valve (general purpose valve): A general term for valves with a wide range of uses, also known as general purpose valves. It is not a valve for specific conditions and specific purposes.Although there is no clear definition for general valves, they mainly refer to manually operated globe valves, gate valves, check valves, butterfly valves and ball valves with a pressure lower than 2MPa. The valve housing materials mainly include gray cast iron, ductile cast iron, malleable cas...

  • Is the home tap water main valve selected correctly? Ball valve or globe valve? What's the difference?

    Many valves will inevitably be used during the renovation of the waterway in our family. There are actually two types of valves commonly used in families: the first is a ball valve, and the second is a stop valve. So which of these two valves is more suitable for use in our family? What is the difference between the two? It is estimated that many friends do not know it well. For example, a friend now asks such a question: Is a stop valve or a ball valve installed on the main PPR pipe of the tap ...
