Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hydrogen drying tower structures, and in particular relates to a hydrogen drying tower pressure gauge device. Background Art
[0002] Among gases, hydrogen has the best thermal conductivity, and its thermal conductivity is 6.69 times that of air. Hydrogen has a very high diffusion rate, and hydrogen is basically completely diffused at a distance of 0.25m from the leak point. Therefore, when hydrogen is used instead of air as the cooling medium of the generator, on the one hand, the thermal conductivity of the insulating material itself can be improved, and on the other hand, the thermal conductivity in the gap of the insulating layer can be improved, thereby improving the cooling effect of the generator. However, the hydrogen cooling system of the generator has high requirements for the purity of hydrogen. If water vapor or oxygen is mixed in, it will corrode the internal components of the generator. Therefore, it is usually necessary to set up a hydrogen drying tower to remove water vapor from hydrogen, and a pressure gauge needs to be set on the hydrogen drying tower for pressure monitoring. The pressure gauge of the hydrogen drying tower needs to be disassembled and inspected regularly. In the process of disassembling and reinstalling the meter, air will inevitably be introduced into the hydrogen tower, which will have an adverse effect on the purity of hydrogen during long-term operation. Utility Model Content
[0003] Aiming at the technical problem that air is easily mixed into the pressure gauge of the existing hydrogen drying tower during the disassembly and assembly process, the utility model provides a pressure gauge for the hydrogen drying tower, which can effectively prevent air from mixing into the pressure gauge during the disassembly and assembly process.
[0004] The utility model provides a hydrogen drying tower pressure gauge device, comprising a mounting flange, a detection tube, an exhaust pipe, a first valve, a second valve, a one-way valve and a pressure gauge, wherein one end of the detection tube is connected to the mounting flange, the other end of the detection tube is detachably connected to the pressure gauge, the first valve is arranged at one end of the detection tube, the exhaust pipe is connected to the other end side wall of the detection tube, and the second valve and the one-way valve are arranged on the exhaust pipe in sequence.
[0005] Furthermore, a first flange is provided at the other end of the detection tube, and a second flange is provided at the sampling port of the pressure gauge, and the first flange and the second flange are detachably connected.
[0006] Furthermore, a plurality of mounting holes are arranged at intervals on the mounting flange.
[0007] Furthermore, the first valve and the second valve are electrically controlled valves.
[0008] The pressure gauge device of the hydrogen drying tower is provided with a detection tube between the pressure gauge and the mounting flange. The pressure gauge can be extended out of the top cover plate of the hydrogen drying tower through the detection tube, so as to facilitate the recording of the value of the pressure gauge during daily inspection. On the other hand, when the pressure gauge needs to be dismantled for inspection regularly, the first valve can be closed and the pressure gauge can be dismantled to avoid mixing of air during the dismantling process; when the pressure gauge is reinstalled, the first valve and the second valve can be started first, and the air in the detection tube can be exhausted through the one-way valve, and the second valve can be closed after the air is exhausted, so as to avoid mixing of air in the hydrogen drying tower.
