| No. | Name | Description | Reference picture |
|---|---|---|---|
| 11 | Gaojia three-way valve | Valve body type: free forging, casting. The flow equalizing cover structure is adopted to slow down the medium erosion and guide the valve freshness, with small vibration and low noise. |
|
| 12 | High inlet valve | This valve is used in conjunction with the Gaojia check valve (together known as the Gaojia joint valve). It is installed at the inlet and outlet ends of the Gaojia respectively to protect the Gaojia. |
|
| 13 | Gaojia check valve | The high-intensity inlet valve is used in conjunction with this valve (collectively called the high-intensity combined valve), which is installed at the inlet and outlet ends of the high-intensity outlet respectively to protect the high-intensity inlet. |
|
| 14 | Air discharge check valve | The valve consists of a check valve, a recirculation bypass valve and a throttling device. When the medium flows back, the main channel is closed with the help of medium pressure and spring force, and the bypass valve is opened at the same time. When the main valve is fully open, the bypass valve is closed. |
|
| 15 | Extraction check valve | This valve is a special quick-closing valve to protect the steam turbine generator set. When the steam turbine unit sheds load or the medium pressure in the steam turbine drops suddenly, the valve closes quickly to prevent the medium from flowing back into the steam turbine and causing damage to the turbine blades. |
|
| 16 | Spring full lift safety valve | Used for power station boilers or pressure vessels to prevent their pressure from exceeding the allowable pressure value. |
|
| 17 | Main safety valve (PN40) | It is used for temperature and pressure reduction devices and is used in conjunction with GA49bH-40DN25 pulse safety valve to prevent the pressure from exceeding the allowable pressure value. |
|
| 18 | Pulse safety valve (PN40) | It is used for temperature and pressure reduction devices and is used in conjunction with the A49aH-40 type main pressure regulator to prevent the pressure from exceeding the allowable pressure value. |
|
| 19 | Main safety valve (PN100) | It is used for temperature and pressure reduction devices and is used in conjunction with GA69bH-100/1001DN20 pulse safety valve to prevent the pressure from exceeding the allowable pressure value. |
|
| 20 | Pulse safety valve (PN100) | It is used for temperature and pressure reducing devices and is used in conjunction with the A49aH/A69aH-100 main safety valve to prevent the pressure from exceeding the allowable pressure value. |
