Stainless steel discharge valve installation and maintenance

1, the discharge valve should be stored in a ventilated and dry warehouse as a whole, non-stacking or open storage, the valve diameter at both ends of the board to be blocked. 2, according to the media performance and life, should always check the top of the valve body PTFE ring and orifice Department of PTFE sheet. If found to be damaged should be replaced and re-used. 3, before installation should pay attention to the various departments of the screw force balance, lifting (activities) is flexible. 4, unfolding the discharge valve to be carefully checked before installation of the valve, and clear the valve internal transport, storage damage caused during the process. 5, when the material is blocked, you can use the metal rod or hard tools to clear, pay attention to the use of metal rods or hard tools do not damage the disc and seal contact surface. 6, discharge valve should try to avoid the alternating use of acid-base medium (except in the reaction medium), so as not to shorten the life. 7, the next show-style discharge valve should be installed in the absence of severe vibration and impact of the place, and the use of the valve without damage to the site. 8, if the valve surface is found to be damaged immediately, you can use special materials to repair the affected area, or commissioned by the production units.

Chrome Plating Production Line

Metal electroplating line is widely used in aircraft and auto parts, machinery parts, metal, hardware processing industries, including cooper plating, silver plating, zinc plating, nickel plating, gold plating, chrom plating, anodizing, electrophoresis production line,etc.

Chrome plating refers to the act of plating chromium as a plating layer on other metals.
Chromium is a kind of silver-white metal with a bluish tint. Metal chromium is easily passivated in the air, and a very thin passivation film is formed on the surface, thus showing the properties of precious metals.
The chromium-plated layer has a very high hardness, and its hardness can vary within a wide range of 400-1200HV according to the composition of the plating solution and process conditions. The chromium-plated layer has good heat resistance. When heated below 500℃, there is no obvious change in gloss and hardness. The temperature above 500℃ starts to oxidize and discolor, and the hardness starts to decrease when the temperature exceeds 700℃. The friction coefficient of the chrome layer is small, especially the dry friction coefficient, which is the lowest among all metals. Therefore, the chrome-plated layer has good wear resistance.
