sampling valve is a pipe or equipment used to obtain samples of the valves in the media, often in the many needs media samples for chemical analysis of the situation, many will be using specialized sampling valves. Works in accordance with the sample or the performance of different sampling valve is divided into three categories, including double to open the valve, valve and flange clip with insulation jacket of the sampling valve.

1 , double opening valve

double to open the valve is more commonly used sampling valves, ball valves are usually composed of two connected, characterized by a sampling of security, stability. In the sampling process, first turn off double to open the valve near the equipment and pipelines A valve, then open the B valves, two valves so that media flows the space between, and then close the B valve open A valve, the sample containers placed in the sample population sampling media in full bloom.

2 , flange clip valve < span lang = "EN-US ">

flange clip valve principle is that the top of the vertebral body through the valve stem and valve seat to seal the cone hole, in the sample to enhance the use of hand wheel valve stem position, will stem and cone separation, so that cone in the medium can flow into the sample containers in the external.

3 , sampling valve with thermal jacket

sampling valve during the use, if you encounter need to use the insulation jacket, it should be note that the operation can not be completely melted before in the media did not break open the valve, must wait until crystallization within the valve to open the valve after melting, or likely to cause accidents.

insulation jacket to use when sampling valve, but also careful not to force open the valve, the valve can not be opened if you encounter the situation, avoid using the extended arm, this will cause the valve the stress caused by too large spool and the valve stem off, or lead to sample damage components, leading to potential safety problems.
