3. Design of equal width of sealing surfaces of valve bodies and plugs The main sealing surface of the pressure-balanced plug valve is a cone surface. The angle of the cone surface affects the consistency of the sealing surface width, thereby affecting the sealing of the entire valve. The sealing cone surface and other vertex design scheme is that the cone angle of the sealing surface of the plug and the valve body is the same as the plug flow channel window angle vertex (shared vertex O1). At this...

High-temperature and high-pressure valves, also known as high-temperature and high-pressure control valves, play a vital role in industrial automation process control. They act as the final control elements by receiving control signals from the regulating control unit and using dynamic operation to adjust process parameters such as fluid flow, pressure, temperature, and liquid level. Generally, they consist of an actuator and a valve. Depending on the stroke characteristics, high-temperature and...

Abstract: The research background of high-pressure and large-diameter plug valves is introduced. The valve is analyzed from the equal deformation design of the valve body sealing surface, equal width of sealing surfaces of valve bodies and plugs, low torque of valves, lasting balance of sealing and anti-deformation. The matters needing attention in the design and manufacturing process of high-pressure and large-diameter pressure-balanced plug valves are obtained. High-pressure and large-diameter...

Valve seats A valve seat is a crucial component of a valve. Use elastic sealing materials and a small actuator thrust to obtain a bubble-tight seal. Compressing the sealing stress of the valve seat causes the material to elastically deform and squeeze into the rough surface of the matching metal parts to block all leakage paths. The permeability of the material to the fluid is the basis for small leaks. Valve seats are an essential component of internal combustion engines, playing a crucial role...

Surfacing is a technology that heats alloys with certain properties through a heat source, deposits them on the surface of parts and forms a surfacing layer, thereby repairing the failed parts of the parts and enhancing the surface properties of the parts. Surfacing mainly includes arc surfacing, plasma surfacing and vacuum electron beam surfacing, which has the advantages of lower cost and less consumables. Surfacing is used to repair products with smaller quantities and irregular workpieces, and...
