The Scope Of The Three Valve Group

Jul 08, 2019

The three-valve group consists of a valve body, two shut-off valves and a balancing valve. Operation procedure when the differential pressure transmitter is put into operation: First, open the two drain valves on the differential pressure transmitter, then open the balance valve, and tahen slowly open the two shut-off valves to remove the air or dirt in the pressure guiding tube. When the two drain valves are closed, the balance valve is closed and the transmitter can be put into operation.

The three-valve group is composed of a high-pressure valve and a balance valve. It is used together with a differential pressure transmitter. Its function is to turn on or off the positive and negative measuring chambers and pressure points of the differential pressure transmitter, or The positive and negative pressure measuring chambers are opened and turned on, and the pressure and pressure points are directly connected to the steel pipe, and the connection is welded. Other connections can be used. Please specify when ordering.

The scope of the three valve group: urban construction, chemical, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection.

The three-valve group consists of a high-pressure valve low-pressure valve and a balance valve three valves.

The three-valve group has a wide range of applications, consisting of three valves: high pressure valve, low pressure valve and balance valve. The high pressure valve is connected to the positive pressure chamber of the differential pressure transmitter, and the low pressure valve is connected to the negative pressure chamber of the differential pressure transmitter. The function of the three-valve group is to turn on or off the positive and negative pressure chambers and the pressure guiding pressure tube of the differential pressure transmitter, or to turn on or off the positive and negative pressure chambers. The operating precautions for the three-valve group are as follows:

1. When the pipeline is added to the medium from the initial state (empty), in order to avoid this situation, first close the valves A and B on both sides of the sensor and open the bypass valve C;

2. After the medium is filled with pipes and is approaching smooth and balanced, gradually open A and B to apply pressure evenly on both sides of the sensor;

3. Finally, close the valve C and the sensor starts to work normally;

4. The closing sequence is the opposite of the above.
