Embodiment 1
[0024] The raw gas in the gas cylinder is sent to the high-pressure regulating system by the filter control valve through the filter. The pressure sensor 1 collects the pressure signal and transmits it to the pressure signal processing system for processing. Then the low-pressure regulating system adjusts the product gas end pressure. The pressure sensor 2 collects the pressure. The signal is transmitted to the pressure signal processing system for processing, the switch outlet of the product control valve is connected to the product gas cylinder, and the dynamic mass of the product gas cylinder is weighed through the electronic balance and transmitted to the data processing system, and the raw material and product control are controlled according to the pre-designed quality value Valve one and product control valve two. The switch of pressure gauge and vacuum gauge is automatically controlled by the pressure sensor processing program to obtain accurate vacuum data of the syste...

The invention discloses a novel device for distributing standard gas. In the whole set of device, a raw material gas cylinder is filtered by a filter and then is connected with a raw material control valve; the raw material control valve is connected with a high-pressure adjusting system; the high-pressure adjusting system is connected with a pressure sensor I and then is connected with a low-pressure adjusting system; the low-pressure adjusting system is connected with a pressure sensor II and then is connected with a product control valve, an air release control valve and a vacuum pump valve respectively; a product is placed on an electronic balance; signals of the pressure sensor I and the pressure sensor II and data of the balance are accessed into a signal processing system; and the signal processing system is connected with a data processing system, the air release control valve and a vacuum pump interlocking device respectively. The device can intuitively display the component mass and proportioning, greatly simplifies the gas distribution process and improves work efficiency and weighing accuracy. The system can directly give warning according to the gas distribution components which may cause safety accidents and chemical reaction, so that operation simplicity, safety and quickness of the equipment are greatly improved.
Description
technical field [0001] The invention discloses a gas distribution device, in particular to a novel standard gas distribution device. Background technique [0002] Standard gas is one of the most widely used standard substances in measurement work, and it is widely used in steel, petroleum, chemical, medical, semiconductor, electric power, metal processing and other industries. With the precision of various instruments and meters in industrial production, the requirements for standard gases are also increasing, which is mainly reflected in the continuity of accuracy and concentration. At present, the order of standard gas in the measurement industry is prepared at a specific point according to the user's requirements, but for the multi-point linearity evaluation of the instrument and the linear comparison within a certain range, a single standard gas is powerless. At the same time, many instruments and meters require on-site calibration, and it is inconvenient to carry a...
