Q: the principle of the pneumatic ball valve with unique local answer: love by rotary valve to valve pneumatic ball valve is smooth or congestion, consists of three type ball valve equipped with arrangement of pneumatic actuators, pneumatic actuators are divided into double and single utility type, magnetic valve stem, electricity flows through a successful implementation ball valve switch. Pneumatic ball floating ball valve structure simple, tight sealing ability is good, but the spherical stereo assume office medium load all passed export tightly closed circle, because the problem to consider tightly closed circle material can support to spherical stereo media work load. 。 2, thrust bearing, reduce the stem friction torque, can make the valve stem operation safe and secure for a long period of time. Can successfully implement intelligent stem, quickly turned on or off line, can work on pipe network of stem and management. 5, because materials such as ptfe have satisfactory self lubricating oil, and the spherical stereo friction loss is small, so the use fixed number of year of the survival of the length of the pneumatic ball valve. Marine valve 3, seat tightly sealed performance is good, see fit and use of ptfe tightly closed ring made of elastic material, such as structure to facilitate tightly closed, pneumatic ball valve of the valve closure and experienced increases as the medium pressure increases. Pneumatic ball valve of the spherical stereo is floating, under medium pressure utility, spherical stereo to initiation of displacement and compression on the outlet tightly closed, ensure outlet tightly closed. 4, the valve stem is tightly closed good, because the valve stem will only be used as rotation and don't do up and down movement, the valve stem packing tightly closed is not easy to damage, and tightly closed experienced increases as the medium pressure increases. Pneumatic ball valve in the line is mainly used to do truncation, distribution, and changes the flow direction of medium. 6, unloading valve stem and valve stem head convex order to avoid the Industrial Valves stem, such as fire cause stem tightly closed mutilate, convex order between the body and also can form metal contact, ensure that the valve stem tightly closed. Pneumatic ball valve switch light, big and small, can make it very large diameter, tightly closed reliable, simple structure, convenient maintenance, often in the closed tightly closed surface and the ball surface, not easily be medium erosion, is mainly used to cut off or connect pipe in the media, can also be used for the regulation of fluid and the stem, it and other valve class in, have the following strengths. 7, anti-static function: between the spherical stereo, valve stem and valve body set up spring, can switch process initiation of electrostatic export. 1, fluid resistance small, pneumatic ball valve is the smallest of all valve fluid resistance in class a, even if is reducing pneumatic ball valve, the fluid resistance is small. Pneumatic ball valve and plug valve is belong to one type of valve, only it's closure of a spherical stereo, spherical solid core line around the body as a rotation to achieve a kind of open and close the valve. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
