Self-closing Integral Sampling Valve

Design Standards

Can be designed and manufactured according to national standards, American Standards and other standards according to requirements

Structural Features

● The integrated sampler is made of forged blocks to meet the sampling requirements of media with various pressures, temperatures and viscosities;

● The integrated sampler adopts a friction-free design spring to automatically close the handwheel, making it easy to operate and easily realize sampling;

● The integrated sampler adopts a full-diameter design with no dead angle, and a residual-free design at the sampling outlet. The needle-inserted sampler adopts a positive nitrogen blowing method in the center hole of the valve stem to ensure that there is no medium residue at the outlet of the sampler and the sampling needle;

● The integrated sampler valve core adopts a long-stroke conical plunger soft and hard double seal zero-leakage design. It has a powerful pressure reduction function to control the sampling flow rate and avoid overflow and explosion of the bottle. The sampling safety box is designed to isolate sampling and ensure the safety of sampling personnel;

● The integrated sampler shaft seal is designed with soft and hard fillers and multi-layer disc springs to ensure zero leakage of the shaft seal;

● The integrated sampler can be customized designed and manufactured according to customer requirements.

Application Scenarios

Pharmaceuticals, coal chemicals, sewage treatment, and many other fields are waiting for you and me to discover together.

Application Case 1: In the field of fine chemical industry, the preparation method of silicone oil is to prepare high-boiling silicone oil from secondary high-boiling substances of organic silicon. During the preparation process, different mass fractions of methanol need to be added dropwise at different times. Before alcoholysis, the percentage content of methanol needs to be tested. Without affecting production or stopping, choosing Wanlong sampling valve can perfectly solve this problem, providing reliable quality assurance for customers 'products and improving customers' production efficiency.

Application Case 2: The customer belongs to Sinochem Group and is the world's leading comprehensive service provider for polymer additives. The customer originally used a simple ordinary valve for sampling at a high temperature of 150 ° C. A bypass was needed during installation, which made online and quantitative sampling impossible. In addition, due to the pressure of the medium in the pipeline, there is a safety risk to the operator during sampling; After many exchanges with customers and analysis of different working conditions, Wanlong Machinery R & D Center has designed cut-off sampling valves and stopcock sampling valves for different media, different temperatures and different sampling volumes, realizing online, cavity-free and no pressure, ensuring that the sample liquid is non-contaminated and the safety of operators, and at the same time improving the efficiency of sampling work.
