According to the personage inside course of study says, the origin of the name of the thread ball valve, mainly attributed to it and pipeline connection way of threaded connection on the specific material it was divided into carbon steel, stainless steel, alloy steel, low temperature steel and ball mill cast iron and other materials. So, than the other ball valve, screw ball valves what characteristics? 1, thread ball valve on the structure generally divided into integral, two stages and three, each structure layout reasonable, aesthetically pleasing, accord with the aesthetic view of most consumers, two of the chip, three chip thread ball valve connection mode and adopted b-weld and socket weld mode, and with the international standard support platform and the locking device, driving mode can be divided into manual, electric and pneumatic in three different modes. 2, seat is adopted elastic seal structure, the easy on and off, the Industrial Valves stem part of the application is pour sealing bottoms type structure, this effectively avoid the abnormal stem was rushed out of the cavity.

Due to its simple structure, light weight, more can reduce the pressure of pipeline. According to the experimental data research proves that thread ball valve is available in 1 - 4 mpa and the working temperature in - 29 ~ 180 degrees Celsius under the environment of truncation and through pipes in the medium, and medium not only include who, gas, steam includes oil, nitric acid and acetic acid and other chemicals.
