The working principle of micro electric pneumatic valve ball

pneumatic ball valve is made up of cock, evolved from its opening and closing as a sphere, using a sphere around the axis of the pneumatic valve stem rotation o the realization of the aim of opening and closing. Pneumatic ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium, designed to open V of the pneumatic ball valve also has a good flow regulating function. Pneumatic ball valve not only simple structure, good sealing performance, and within a certain range of nominal pass after small volume, light weight, less material consumption, installation size is small, and the drive torque is small, easy to operate, easy to realize the rapid opening and closing, pneumatic ball valve is one of the fastest growing pneumatic valves varieties in last decade. Especially in America, Japan, Germany, France, Italy, and west, Britain and other developed countries, pneumatic ball valve has a very wide range of use, using the variety and quantity continues to expand, and to high temperature and high pressure, big, high sealing, long life, good regulation performance, and a pneumatic valve multifunctional direction, its reliability and other performance indicators have reached a higher level, and has set up a brake part, pneumatic valve, globe pneumatic valve, pneumatic valve throttle. The technological progress as the pneumatic ball valve, in the foreseeable within short time see, especially on oil and gas pipeline, oil cracking device, and the nuclear industry will have a wider range of application. In addition, in other industries in large and medium caliber, low and medium pressure field, pneumatic ball valve will also become one of the leading pneumatic valve type. Pneumatic ball valve is one of the century s pneumatic valve, in half a century, pneumatic ball valve has developed into a major pneumatic valve class. Pneumatic ball valve is mainly used to cut or connect medium, can also be used for regulation and control of the fluid, v-shaped ball pneumatic valve can compare accurate flow regulation and control, pneumatic valve is used to assign the 3-way ball medium and change the flow of medium. Compared with other types of pneumatic valve, pneumatic ball valve has the following several advantages:

, small fluid resistance, pneumatic ball valve is for all pneumatic valve minimum fluid resistance among the class a, even reducing pneumatic ball valve, the fluid resistance is small.

, switch is quick, convenient, as long as the pneumatic valve rod rotation °, completes the pneumatic ball valve fully open or close the action, it is easy to realize rapid opening and closing.

, sealed performance is good. Pneumatic ball valve pneumatic seat sealing generally use the elastic materials such as teflon, easy to guarantee the seal, and pneumatic ball valve sealing force with medium pressure increases.

and reliable pneumatic valve stem seal. Pneumatic ball valve open/close the pneumatic valve stem only for rotary motion, thus the pneumatic valve stem packing seal is not easy to be destroyed, and pneumatic valve stem pour sealing sealing force with medium pressure increases.

do ° rotation, pneumatic ball valve opening and closing, so easy to achieve automatic control and remote control, pneumatic ball valve can be configured pneumatic equipment, electric equipment, hydraulic equipment, gas liquid linkage or electro-hydraulic linkage.
pneumatic ball valve installation instructions:

, pneumatic ball valve before and after the line has been ready. Before and after the pipe shall be concentric, two flange sealing surface should be parallel. Pipe should be able to withstand the weight of the pneumatic valve, ball or piping must be equipped with appropriate support.

sweep, blow the pipeline before and after pneumatic valve, oil, remove the pipe welding slag, and all other impurities.

, check the pneumatic ball valve, pneumatic ball valve is in good condition. The pneumatic valve fully open full closed several times to confirm they work.

, down the ball on the other side of pneumatic valve protection on the connecting flange.

remove potentially some dirt, check the pneumatic valve hole, and then wash the pneumatic valve hole. Between pneumatic valve seat and the ball even if only small particles of foreign matter may also damage the pneumatic valve seat sealing surface.

, the pneumatic valve is installed on the pipeline. Any end of the pneumatic valve can be installed at the upstream end. Pneumatic valve driven by the handle can be installed on the pipeline at any position. But with gear box or pneumatic actuator pneumatic ball valve should be installed upright, is installed in a horizontal pipe, and drive in the pipeline.

, pneumatic valve, flange and pipe flange gasket fitted according to the requirements of pipeline design.

, flange bolts need to be symmetrical, successive, evenly tighten.

, pneumatic pipeline connection ( Using pneumatic drive.

several times, drives the ball pneumatic valve opening and closing operation, should be no sluggish acerbity, confirmed that they work.

, according to the requirements of pipeline design of pipeline between the pneumatic ball valve and the flange joint surface of the sealing performance.
