Fuel gas pressure regulating box

Abstract

The invention relates to a fuel gas pressure regulating box. The box comprises a main body framework. The main framework comprises a bottom frame, vertical columns distributed at intervals are fixed to the four sides of the bottom frame, a top cover assembly is installed on the upper side of the main framework, and end plate assemblies are installed at the two ends of the main framework respectively. Side door assemblies are arranged between every two adjacent vertical columns on the two sides of the main framework respectively, and each side door assembly comprises a door lintel, a door frameand a door body. Each door body comprises a side frame, a door plate and a sound insulation plate, wherein the door plate and the sound insulation plate are fixed to the side frame at an interval, aventilation hole is formed in the upper half portion of the door plate, a first sound absorption plate is arranged on the side, opposite to the sound insulation plate, of the door plate, the top of the first sound absorption plate is lower than the ventilation hole, a gap is reserved between the bottom of the sound insulation plate and the bottom edge of the side frame, a second sound absorption plate is arranged on the side, opposite to the door plate, of the sound insulation plate, a gap is reserved between the second sound absorption plate and the first sound absorption plate, and a third sound absorption plate is arranged on the other side, opposite to the door plate, of the sound insulation plate. The pressure regulating box has the advantages of being simple in structure, small in occupied space, good in ventilation effect, high in noise reduction capability and high in safety.

Description

technical field [0001] The invention relates to a box body, in particular to a gas pressure regulating box for natural ventilation and noise reduction through a door body. Background technique [0002] The pressure regulator is an important device in the gas pipeline network, which plays the role of regulating and stabilizing the pressure. Because the regulator will generate a lot of noise during the working process, the field usually installs the regulator and related equipment in the regulating box to achieve the purpose of noise reduction; and because the gas is a flammable and explosive gas, according to industry requirements , The regulating box should have the function of natural ventilation, and its two sides should be designed as door structures, so as to enter and exit the pressure regulating box and quickly release the gas in the box. In order to meet the above requirements, in the prior art, an air inlet and an air outlet are usually provided at one or both ends ...

AI Technical Summary

Problems solved by technology

The surge box with this structure is not only complex in structure, takes up a lot of space, and has high cost, but also has poor natural ventilation effect because of the small ventilation volume of the air inlet and exhaust outlet.
