Suitable for all kinds of media in petrochemical equipment, toxic and harmful, inflammable and explosive medium and low pressure gas medium without leakage sampling. The collected samples have strong authenticity, high accuracy and no residual liquid/gas emission.
The working principle of hydrogen sealed sampler mainly includes sampling principle, sealing principle and sampler structure. The core of the sampling principle is to ensure the accuracy and reliability of the sampling while preventing the sample from being contaminated or damaged.sampling system The principle of sealing means that during the sampling process, the sampler is kept closed with the external environment to prevent interference or pollution caused by external air or other substances to the sampling process. The sampler is usually composed of a sampling part, a sealed part and a control part. The sampling part includes a sampling head, a sampling pipe and a sampling bottle, which are used to collect and store samples. The closed part includes a closed valve, a closed membrane and a closed chamber and other components for maintaining the isolation of the sampler from the external environment.
Main feature
Airtight: The hydrogen sealed sampler adopts a completely closed design, and the shell, valve and connector of the equipment are made of high-strength and corrosion-resistant materials to ensure that the sample is completely isolated from the external environment during the sampling process.
Safety: The sampler is usually equipped with a variety of safety protection devices, such as safety valves, pressure relief valves, pressure gauges, pressure sensors, temperature sensors, leak detectors, combustible gas and toxic gas detection and alarm devices, etc., to ensure the safety of the sampling process.
Accuracy: The sampler achieves accurate collection and storage of hydrogen samples through precise sampling pipes and sampling bottles and other components to ensure the reliability of sample analysis results.
Convenience: The sampler usually has a humanized operating interface and control system, and the operation site sets a simple and clear operating process and precautions, which is convenient for the operator to use.
Technical parameter
Scope of application: It is suitable for collecting liquid, gas, liquefied gas and mixed gas-liquid medium with most physical and chemical properties
Sampling temperature: -20 ~ 450℃
Design pressure: 0 ~ 20.0MPa (In order to ensure the sample circulation, the sampling inlet/outlet pressure difference is required to be greater than 0.01Mpa, if not meet the working conditions can be assembled booster pump)
Structure composition: closed sampler by the box, valve fittings, sampling cylinder/closed pressure sampling bottle, flange, pressure gauge and other components
Function selection:
Can choose cycle, purge, quantification, filtration, decompression, cooling, heat exchange, heat tracing, electric heating, pressurization, gas-liquid separation, linkage, condensation and other functions; It can also be equipped with adsorption tank, temperature meter, buffer, pipeline sight mirror, liquid level meter, rotor flowmeter, check valve and other accessories.
The user shall provide the company's sales and technical personnel with effective field sampling medium pressure, temperature, as well as the type of media and the specific field sampling environment. Optional valve fittings brand can be specified for closed sampler! The default quotation is the brand of valve fittings selected by the company's self-sealing sampler.

Xuanzong was furious and sent messengers to Pegasus countries in the Western regions to ask them why they were stingy in offering treasure and jade. The Western regions said, "That's not true, we often pay tribute, but every time we pass through Xiaolu, it will be taken away, so we can't get to Chang 'an." The emissary reported the situation to Emperor Xuanzong, who ordered an immediate attack on Xiao Bolu. Boru was an ancient country, originally in the northern part of present-day Kashmir. The early Tang Dynasty was founded, Tubo was strong, broke the Bolu, divided it into two, and the one that remained in place was called the big Bolu, and moved to the northwest to the present Gilgit and Skardu regions, called the little Bolu. The location of the little Bolu was on the throat road of the Western regions leading to the Tang Dynasty. At first, the Tang Dynasty had a good relationship with the younger Bolu. During the Kaiyuan period, King Xiao Bolu went to Chang 'an to pay tribute and was received by Emperor Xuanzong. Therefore, when Xiao Bolu was attacked by the Tubo, the Tang Army came to the rescue.
