How to prolong the service life of the valve

Dregs of pipe welding slag, rust, solidification, wire, cloth, etc. in the throttle, steering parts caused by blocked or stuck valve fragments, often occurs in the new operation system and overhaul operation after the initial. This is the most common fault. Encounter this situation, must be disassembled for cleaning, remove residue, such as the sealing surface is damaged should be grinding; at the same time, open the bottom plug, to flush slag and the pipeline flushing. Before operation, to adjust valve fully open, and then let the media flow into the normal operation after a period of time.

At the beginning of the use of ceramic control valve to work as much as possible, such as 80%. In this way, the initial impurity pipe erosion, wear and other damage occurred in part of the valve core is damaged place, remove the impurities in the pipeline, then regulating valve opening adjustment to the normal opening is slightly larger, with an increase in the flow of the destruction of fluid on the spool,, the corresponding opening decreases, so continue to disrupt the gradually shut down, so take advantage of all of the spool, until the roots spool and sealing surface damage, can not be used so far.

We calculate the correct CV through the CV value calculation formula to select the appropriate valve diameter. In the same flow of the case, the smaller the valve diameter, the faster the flow of fluid, the media on the spool and seal the more severe erosion. It is suggested that the user can increase the caliber of the valve properly, so as to reduce the effect of wear and tear.

Shift the serious damage to the secondary position to protect the sealing surface of the spool valve seat and the throttle face. Usually ceramic ball valve is the most serious erosion, the fastest flow is fluid inlet at the lower part of, for the now three piece ceramic valve structure, will be able to use the ball core reversing, such a ball core can be at the entrance to use four times and 4 times longer life of the valve so that.

Ceramic control valve initially used two pieces of structure, in order to more reasonable structure of the valve, the now commonly used three piece structure, this structure has a dual seat, so also has a double sealing characteristics. At the same time, in the selection of ceramic ball valve when the choice of attention to the transition of the design of the valve, so that the valve can reduce the impact of the fluid.
