Stainless steel ball valves are reducing and generally not reducing channel two structures. No matter the structure, stainless steel ball valve flow resistance coefficient is small. Especially the so-called full flow type, i. e. , not reducing ball valve, due to its channel diameter equal to the inner diameter pipeline, local resistance loss only equivalent length of pipe friction resistance, namely in all valves, the ball valve minimum flow resistance. Stainless steel ball valve just has to rotate 90 degrees of operating and small rotational torque can be closed tight. Full equality of the valve body cavity for medium resistance is very small, straight flow channel. Stainless steel ball valve itself is the main characteristics of compact structure, easy operation and maintenance, and is applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be a whole, also can be combined. This paper briefly describes what are restrictive factors in the process of stainless steel ball valve is in use. Stainless steel ball valve is limited by temperature and pressure: nameplate shows a ball valve under the maximum and minimum operating temperature allowed by the maximum operating pressure. Using PTFE or RTFE seat and seal material, operating temperature should be between - 290 - c to 2000 c. Other types of operating temperature of the seat and seal, should check by KI factory. Stainless steel ball valve nominal pressure level ( PN) , can show that the maximum working pressure in normal temperature condition. ( For example: PN4. 0, which indicates that its operating temperature in - 290 - c - 380 c when the maximum working pressure for 40 Bar ( 4. 0MPa) ) 。 Stainless steel ball valve is to rely on the working principle of rotary valve core to keep the valve open or closed. Stainless steel ball valve switch lightweight, small size, can make it big caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries. Stainless steel ball valve and plug valve is belong to one type of valve, only its closure is a ball, the ball around the center line of the body as a rotation to achieve a kind of open and close the valve. Stainless steel ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. Stainless steel ball valve is widely used a new type of valve. Stainless steel ball valve position according to the channel can be divided into straight-through, three general formula and right Angle type. Tee stainless steel ball valve has a T and L. T can make three orthogonal pipes unicom and cut off the third passage, shunt, rivers. L can only connect two orthogonal pipes, cannot maintain the third pipeline connected each other, only assigned role. 1, tee stainless steel ball valve adopts the integration of structure in the structure, four plane seat seal, flange connection, high reliability, realize the lightweight design. 2, the 3-way ball core points T and L, and long service life, the flow capacity is big, small resistance 3, stainless steel ball valve by acting cent two kinds of single and double action type, the characteristic of single acting is once the power failure occurs, stainless steel ball valve will be in a state of control system requirements. Stainless steel ball Industrial Valves just has to rotate 90 degrees of operating and small rotational torque can be closed tight. Full equality of the valve body cavity for medium resistance is very small, straight flow channel. Stainless steel ball valve to reduce the resistance of the pipeline system has two ways: one is to reduce the fluid velocity, therefore need to increase diameter and valve size, for the efficiency of pipeline system tends to produce adverse effect, especially for conveying system at low temperature ( Liquid hydrogen) Is very bad. So why has the characteristic of improve the service life of the stainless steel ball valve? 1, reduce the local resistance of the valve, therefore, ball valves have naturally become choice. 2, the ball valve open/close switch quickly and conveniently. Since only the ball valve in the general case rotates 90 ° completes the fully open or close the action, it is easy to realize rapid opening and closing. Can realize the rapid opening and closing, some of the structure of the opening and closing time is only 0. 05 ~ 0. 1 s to ensure that can be used to test the automation system. Quick opening and closing valves, no impact on the operation. 3, ball valve sealing performance is good. The vast majority of ball valve seat is made of elastic material such as ptfe, sealing pair of metallic and non-metallic materials, often referred to as soft seal. In general, soft seal sealing easy to guarantee, and the machining accuracy and surface roughness on the surface of the sealing requirement is not high. 4, long service life of ball valve. Because ptfe have good self-lubrication, and sphere of friction and wear is small, and because the ball processing technology improvements, reduce roughness, thus improve the service life of the ball valve.
