1. Introduction of 1151 flange type three valve

法兰式三阀组 组与1151系列罗斯蒙特电容差压变送器配套安装,用于从引压点将信号引入1151系列差压力变送器正/负测量室,使引压点与测量室接通或断开,通过法兰与变送器直接连接。 The 1151 flange type three-valve manifold group is installed together with the 1151 series Rosemount capacitive differential pressure transmitter to introduce signals from the pressure point to the positive / negative measurement room of the 1151 series differential pressure transmitter to make the pressure point The chamber is switched on or off and directly connected to the transmitter via a flange.

Two, 1151 flange type three valve role :

1. When the medium is added from the initial state (empty), the pressure on both sides of the sensor will suddenly change and the pressure difference will increase. To avoid this, the valves A and B on both sides of the sensor should be closed and the bypass valve C opened.
2. After the medium is filled with the pipeline, and it is close to being stable and balanced, gradually open A and B, so that the pressure is evenly applied on both sides of the sensor;
3. Finally close valve C, the sensor starts to work normally;
4. The closing sequence is opposite to the above situation;
5. After cleaning the pipeline for a period of time, the sensor part is not affected (the pipeline is bypassed).
 

Third, 1151 flange type three valve group structure:
Type 1151 three-valve unit is suitable for supporting with the 1151 series of capacitive differential pressure transmitter products from S. Monte. The function is to introduce signals from the pressure point to the positive and negative measurement room of the 1151 series differential pressure transmitter to make the pressure point Connected to or disconnected from the measurement room, it is an indispensable accessory for the 1151 capacitive transmitter.
