System and method for identifying inlet water of gas path and draining water of pump suction type gas detector

Abstract

The invention relates to the technical field of gas detection, and discloses a system and a method for identifying inlet water of a gas path and draining water of a pump suction type gas detector, the system comprises a buffer container, a first branch pipe communicated with the buffer container is arranged at the top of the buffer container, and a second branch pipe communicated with the first branch pipe is arranged on the first branch pipe. The first branch pipe and the second branch pipe are each provided with a three-way electromagnetic valve, the end, away from the buffer container, of the first branch pipe is connected with a direct-current diaphragm pump, the air suction end of the direct-current diaphragm pump is communicated with the other end of the second branch pipe, and the three-way electromagnetic valve on the first branch pipe is connected with a drainage air inlet pipe. According to the scheme,a floater liquid level sensor is arranged on a gas detection gas path, whether accumulated water exists in the buffer container or not can be detected in real time, when water exists, the three-way electromagnetic valve, the direct-current diaphragm pump and the drainage gas inlet pipe are matched with one another, the accumulated water is discharged, and the functions of automatically recognizing and discharging liquid are achieved; and failure of the gas sensitive element in the gas detector due to water inflow is effectively prevented.

Description

Technical field [0001] The present invention relates to the field of gas detection techniques, and in particular, a system and method for identifying and draining a gas path water in a pumping gas detector. Background technique [0002] The pump suction gas detection system consists of a built-in air pump, a gas path, and a gas detector. On the prior art gas detection gas path, there is generally no intake water and drainage mechanism. If the water is encountered, the gas is inhaled by the gas pump. Inside the detector, the inner gas sensitive element of the gas detector is damaged. Inventive content [0003] It is an object of the present invention to solve the disadvantages of the prior art, and a system and method for which a pumping gas detector of a pumping gas detector is proposed and drained. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A systematic water inlet water in a pumping gas detector identifies a...

Problems solved by technology

[0002] The pump-suction gas detection system is composed of a built-in air pump, gas circuit and gas detector. The gas detection gas circuit in the prior art generally has no water inlet and drainage mechanism. If there is water in the system, the gas will be sucked in by the air pump In the detector, the inner gas sensor of the gas detector is damaged
