The working principle and characteristics of non retention ball valve

Ball valve, a valve whose opening and closing parts (balls) are driven by the valve stem and rotate around the axis of the ball valve It can also be used for fluid regulation and control, in which the v-ball core of the hard sealed v-ball valve has a strong shear force between the v-ball core and the metal valve seat of hardfacing carbide, which is especially suitable for medium containing fiber, small solid particles, etc On the other hand, the multi-way ball valve can not only flexibly control the confluence, diversion and flow direction switching of the medium, but also close any channel to connect the other two channels This kind of valve should be installed horizontally in the pipeline 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 class in a short period of 40 years In the western developed countries, the use of ball valve is increasing year by year In China, ball valve is widely used in petroleum refining, long-distance pipeline, chemical industry, papermaking, pharmaceutical industry, water conservancy, electric power, municipal administration, steel and other industries, and plays an important role in the national economy It has the action of rotating 90 degrees The plug body is a sphere with a circular through hole or passage passing through its axis The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline It can be closed tightly with only 90 degree rotation and a small rotation torque The ball valve is suitable for use as switch and cut-off valve, v-ball valve In addition to the pipe parameters, special attention should be paid to the environmental conditions of the electric valve Because the electric device in the electric valve is an electromechanical device, its use state is greatly affected by its use environment In general, special attention shall be paid to the use of electric ball valve and butterfly valve in the following environment Today I would like to introduce to you the non retention ball valve This type of ball valve series is a sanitary valve for material transfer control It is widely used in food, beverage processing, pharmaceutical and chemical industries This type of ball valve is made of stainless steel 304316l, seal: PTFE, design standard: iso5211.iso2037-92, test and inspection standard: gbt13927-2008 Its working principle is: through 90 degree rotating handle, the manufacturing ball with through cavity is driven, so as to open or close the valve, thus realizing the control of medium flow You also have the following six features: 1 Stem anti flying design 2 Valve body and bonnet connection with positioning step design 3 Full flow 4 No retention design 5 Stem seal packing self compensation device 6 Padlock device Now, what are the working principles and features of the non retention full package ball valve after the above brief introduction? Do you know better? I also hope this article can help you.
