Sanitary sampling valve

Sanitary sampling valve

Product Description Sanitary sampling valve is used to obtain the pipeline or equipment in the media samples of the valve, in many need to often on the media samples of chemical analysis of the occasion, will use a special health level sampling valve. According to the working principle or performance at the time of sampling, the hygienic sampling valve is divided into three categories, including double open valve, flange clip valve and sanitary jacket with sanitary sampling valve.

1, double open valve

Double open valve is the more commonly used hygienic sampling valve, usually consists of two connected ball valve, which is characterized by safe sampling and stability. In the sampling process, first close the double open valve near the equipment and pipeline A valve, and then open the B valve, so that the media into the space between the two valves, and then close the B valve to open the A valve, the sampling vessel placed in the sampling Mouth containing the sampling medium.

2, the flange clip valve flange clip valve principle is through the stem at the top of the vertebral body and the valve seat of the cone hole to seal, in the use of hand wheel to enhance the position of the stem, the stem and cone So that the medium in the taper hole can flow into an external sampling vessel.

3, with the insulation jacket sampling valve

Sanitary sampling valve in the use of the process, if you need to use the case of insulation jacket, it should be noted that the operation can not be completely melted in the media before the open valve, you must wait until the valve dissolved in the valve to open the valve, otherwise Easily lead to security incidents.

Sanitary sampling valve using insulation jacket, but also should not be forced to open the valve, if the valve can not open the case, should not use the extension arm, which will cause the valve force is too large and lead to the valve stem and stem Shedding, or causing damage to the sampling parts, resulting in a security risk.
