Common Problems of Forged Steel Valves1
Forged steel valves are mainly suitable for all kinds of fire power station on the pipeline, it can be used to control the flow of various types of fluids such as air, water, steam, corrosive media, mud, oil, liquid metal and radioactive media.
Forged steel valves and other valve products compared to the characteristics of high temperature and pressure, unique self-sealing design, the higher the pressure, the more reliable sealing. Due to the performance of technical characteristics, the special conditions of the product also formed a substitute for other products can not be the characteristics.
Forged steel valves should pay attention to the valve body discharge and silk plug pressure problem. Valve pressure test, the sealed chamber cavity gas and moisture due to rising ambient temperature and pressure, grease when the first discharge pressure relief, in order to facilitate the smooth operation of the grease. After the grease, the air and moisture in the sealed chamber are fully displaced. Timely release valve chamber pressure, but also to protect the use of the valve safety. After the end of the grease, be sure to tighten the sewage and pressure plug plug to prevent accidents. When filling grease, pay attention to the problem of fat evenly. Normal injection of fat, from the mouth of the mouth of the mouth of the fat out of the first fat, and then to the low, and finally high, successive fat. If you do not press the law or not fat, to prove the existence of clogging, timely clearance.
