Efficient air pressure detection device

Abstract

The invention discloses an efficient air pressure detection device which comprises an air pressure lead-in bottle, a bottle cover, a sealing rubber ring, an air pressure lead-in pipe and an air pressure lead-out pipe, one end of the air pressure lead-in pipe and one end of the air pressure lead-out pipe penetrate through the bottle cover downwards and extend into the air pressure lead-in bottle, an air pressure lead-in pipe connector is arranged at the other end of the air pressure lead-in pipe, and an air flow control valve is arranged on the air pressure lead-in pipe, an air flow discharge control valve is arranged on the air pressure lead-out pipe, and the fixed bolt is an outer hexagonal head bolt. The air pressure lead-in pipe is directly inserted into the bottom of a sampler, so thatthe air in the sampling bottle can be thoroughly removed during the sampling process, and the loss of light components in the sample during the sampling can be greatly reduced or eliminated during use, and the accuracy of saturation steam pressure measurement is ensured; and the air flow control valve and the air flow discharge control valve can realize the sealing of the sample after sampling.

Description

technical field [0001] The invention relates to the detection field of a natural gas processing system, in particular to a gas pressure detection device for a steam boiler. Background technique [0002] Special care is required when taking samples for certain tests, and proper sampling methods should be strictly followed to ensure meaningful test results. However, these regulations and requirements are not based on technical means, and still rely to a large extent on the technical proficiency of sampling personnel, which has great uncertainty and leaves hidden dangers for the accuracy of measurement. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a high-efficiency air pressure detection device that can ensure the accuracy of saturated vapor pressure measurement. [0004] To achieve the above object, the technical solution adopted in the present invention is: [0005] The high-efficiency...
