3VR Series three Manifold Valves Constituent structure
The pressure three valve group is mainly composed of a valve body, two stop valves (high pressure valve and low pressure valve) and a balance valve. These three valves communicate with each other to achieve a specific function.
High pressure valve: Usually located on the left side, it is used to control the flow of fluid on the high pressure side.
Low pressure valve: Located on the right, it is used to control the flow of fluid on the low pressure side.
Balance valve: Located in the middle, it is used to balance the pressure in the positive and negative pressure measuring chamber to ensure accurate measurement.
3VR Series three Manifold Valves Working principle
The operating principle of the pressure three valve group is based on the on-off state of its valve. To be specific:
When the high pressure valve and low pressure valve are closed and the balance valve is opened, the pressure in the positive and negative pressure measuring chamber reaches a balanced state, which is conducive to the zero adjustment and calibration of the instrument.
When the high pressure valve and low pressure valve are opened and the balance valve is closed, the pressure at the input end is high pressure and low pressure respectively, and the normal pressure measurement can be performed at this time.
Connection flange: Used to connect the sampler to other equipment or pipes.
Filter: In some cases,custum sampling system it may be necessary to install a filter before the sample tube to remove impurities.
Brackets and fasteners: Used to support and hold the sampler to ensure its stable operation.
On-line sampling valve and needle valve are common types of valves in the industrial field, they play an important role in fluid control, sampling analysis and so on
