High Pressure Bypass Valve

What is High Pressure Bypass Valve？

High Pressure Bypass Valve, also known as HP bypass valve, is a steam regulating valve.High pressure bypass valves are widely used in steam power systems to reduce pressure by throttling and saturating steam by periodic water injection, thereby reducing critical steam parameters. The valve body of this high pressure bypass valve consists of two ball cavities with the largest outer diameter.Its main field of application is high pressure bypass systems for fossil fuel power plants in subcritical and supercritical steam conditions. With the range of valve body materials available, the High Pressure Bypass Valve can be used for the main steam pressures and temperatures of today's most advanced thermal power plants. This valve is designed for cyclic operation of bypass systems. Equipped with hydraulic actuators and necessary safety controls, the valve can be used as a combined safety valve for high pressure bypass and superheater.

The composition of the high and low pressure bypass valve of the steam turbine system:

High pressure bypass control valve, high pressure bypass spray water control valve, high pressure bypass water isolation valve; low pressure bypass pressure reducing control valve, low pressure bypass spray water control valve, low pressure bypass water isolation valve and control system, etc. It can provide complete sets of devices for the control mode and use of supercritical units, including electric, pneumatic and hydraulic.

High Pressure Bypass Valve Function

The valve also has the function of reducing temperature and pressure. Water jets are injected into areas of high velocity steam and turbulent flow. This ensures fine atomization and good mixing of the injected water with the steam, resulting in a very short evaporation length and a uniform temperature distribution at the valve outlet.

Dividing the steam jet into several small jets ensures noise reduction. This cage also prevents water droplets from reaching the pressure boundary wall, thus eliminating any risk of thermal shock.
