â… ï¼ŽProduct Introduction
The pneumatic powder-gas quantitative sampling valve and inline powder sampler are used for online sampling in pipelines, ensuring the authenticity of the sampled medium. It is mainly composed of a valve body, valve core, valve stem, valve seat, high-temperature packing, exhaust port and sampling bottle. The sampling bottle adopts a detachable design; after the sample enters the sampling bottle, the matching bottle cap can seal the sampling bottle to avoid sample contamination. The flow channel of the sampling valve is designed without retention and flow resistance, which will not affect the flow rate. The valve stem drives the valve stem and valve core through the rotation of the handwheel, and the valve core is lifted up and down to precisely control the flow rate and sampling volume, allowing the sample to enter the sampling bottle. Two types of sampling bottles are available: transparent and light-proof. This sampling valve is widely used in pharmaceutical, chemical and food industries.
Ⅱ．Product Features
-
This sampling valve can be installed on the main pipeline. The channel is designed without flow resistance, which does not affect the flow rate of the main pipeline.
-
The valve cover adopts a double-sealing design to prevent medium leakage.
-
The valve stem adopts a double-sealing design, using O-rings and packing for double sealing to prevent medium leakage.
-
The sampling outlet is cone-sealed, which can precisely adjust the flow rate to achieve the required sampling volume.
-
It has light torque and can be operated with one hand for sampling, improving the safety of sampling.
-
The valve body is integrally precision cast and undergoes solution treatment to prevent intergranular corrosion.
Ⅲ．Technical Data
Overview
It is an online sampling valve suitable for high-temperature working conditions, which can realize accurate online sampling of media in pipelines. It has the advantages of no medium retention, no flow resistance, detachable sampling bottle, and adjustable sampling volume, and is widely used in various fields requiring strict sampling.
