The DGC Coal Sample Canister, developed and manufactured by Zhengzhou Huazhi Technology Co., Ltd., is a critical auxiliary device in the mine gas content testing system. Its core functions include the sealed containment and safe storage of drill cuttings samples, making it widely applicable in mine production monitoring, geological exploration sampling, gas prevention research, and other fields. As a commonly used sampling device in the industry, this product offers multiple material options such as stainless steel and alloy, fully adapting to the complex working conditions of different mines.
I. Core Performance Advantages
Customized Service Capability: Zhengzhou Huazhi Technology can flexibly customize DGC coal sample canisters in various specifications (capacity/size), materials (stainless steel/aluminum alloy), and sealing modes based on the customer's actual sampling volume and usage scenarios, accurately meeting diverse sampling needs.
High-Quality Component Configuration: The product's valves are uniformly made of stainless steel, featuring high strength, wear resistance, and corrosion resistance, effectively reducing component wear during long-term use and extending the overall service life of the equipment.
**Process Enhancement: For aluminum alloy coal sample canisters, the thread parts are specially treated with cold鑲嵌 technology, significantly improving the sealing and wear resistance of threaded connections and addressing issues such as thread slippage and sealing failure commonly found in traditional threads.
Strong Environmental Adaptability: The overall product exhibits excellent corrosion resistance, wear resistance, and high-temperature resistance. The stainless steel version remains rust-free even after long-term use, easily handling complex mine environments such as humidity, dust, and extreme temperatures.

High Sealing Standard: The airtightness test can reach 8MPa, ensuring that coal samples do not leak or deteriorate during storage and transportation, thereby guaranteeing the authenticity of test data.

II. Instrument Structure Composition
The structure of Zhengzhou Huazhi Technology's DGC coal sample canister is simple and practical, primarily consisting of two key components:
Canister Body: As the main part that holds the coal sample, it is made of thickened high-quality materials, balancing structural strength and lightweight design for easy operation and portability at mine sites;
Valve: The critical component for controlling coal sample input/output and sealing. Made of stainless steel and processed with precision craftsmanship, it ensures smooth operation and reliable sealing, reducing maintenance frequency.
III. Usage Precautions
To ensure the device's sealing performance and operational safety, Zhengzhou Huazhi Technology reminds users to:
Carefully check whether the sealing gasket is properly installed, without displacement or deformation, before each use;
If aging, cracks, or damage are found in the sealing gasket during routine maintenance, replace it with a new one promptly to avoid coal sample contamination or data deviation due to sealing failure.
