The formation of abnormal pressure rise occurs surprisingly similarly in many gate valve applications, as the two major factors involved in its occurrence are similar in many industrial systems

The important component for adjusting pressure in a piston type pressure reducing valve is the piston plug,

On April 17th, news came from the First Drilling Company of Bohai Drilling Company that the Gao32-Ping4 well, which was drilled by the 70025 drilling team, had completed drilling at 6088 meters,

For stainless steel, it is generally considered that it is not easy to rust, but in fact, stainless steel can also rust.

Flange butterfly valves are mainly used in industrial production pipelines. Their main function is to cut off the flow of media in the pipeline, or to regulate the flow of media in the pipeline.

Hard seal butterfly valve refers to the hard seal with metal materials or other hard materials on both sides of the sealing pair.

Knife gate valve can only be used to cut off rather than to throttle, and gate valve can throttle or switch.

Installation environment and maintenance precautions of butterfly valve

304 austenitic stainless steel (new standard 06Cr19Ni10 steel, old standard 0Cr18Ni9 steel) is widely used in petrochemical, metallurgical machinery,

The installation of safety and relief valves in pressure vessels and the use of stop valves upstream and downstream are considered to be the last line of defense for equipment with internal pressure greater than atmospheric pressure.

Electric gate valve is a widely used valve, which is mainly used in analog quantity regulation of medium flow in liquid, gas and air systems.

In winter, the temperature drops rapidly, and the valve often freezes. At this time, if it is not handled, the pipeline will be prone to failure.

When using the relevant mechanical equipment, if some wrong methods are used, the equipment will be seriously injured.

Valve welding inspection is generally divided into two parts:

Carefully read the valve manual to understand the basic structure and principle.
