( 4) To transfer erosion location method. ( 2) For easy erosion parts of valve core and valve seat, valve stem and hardening treatment of appearance or sees fit and use cemented carbide. ( 5) See fit and use to prevent cavitation of the cavitation. Plug valves have the survival of the fixed number of year long unique place, but the use of inappropriate or Marine valve to reduce the use of its survival of fixed number of year, then how to reasonable to protect it, makes the cock use fixed number of year to extend to live? A summary as follows: ( 1) Prevent the office in a small open degrees. 。 ( 3) See fit and use classification step-down method of high pressure difference regulating valve. Plug valve is mainly be used for medium of open and closed pipelines and facilities. Q: cock prolong life way of answer: cock valve opening and closing is a hole in the cylinder, vertical to the axis of the channel rotate, thus achieve the objectives of the opening and closing the channel. Such as valve selection is too big, in the small open office, under the throttle gap is small, serious erosion, appropriate chooses regulating cock valve diameter, do open degree increased, diplomatic representative large gap, scour is abate, increasing the use fixed number of year of survival.
