Description
Technical field
The utility model relates to gas pressure regulating field, especially a kind of compact gas pressure-regulating box.
Background technique
Along with the change of China's energy resource structure and continuing to increase of environmental protection dynamics, the development and utilization of rock gas is made to obtain swift and violent development.Compressed natural gas is that well head rock gas or the laggard horizontal high voltage of pipe natural gas purification compression are stored and transport, arrives place to use, directly inputs pipe network supply all types of user through multi-stage heat exchanger, pressure regulation.Gas generally could finally will be used by user through the pressure regulation of regulator, and Gas Pressure Regulating Equipment is generally made up of several function module, as pressure governor realizes voltage regulation function; Filter realizes clean filtering function etc.; In recent years, because wideling popularize of the clean energy resourcies such as rock gas, Gas Pressure Regulating Equipment also obtains applying more widely, and therefore relevant departments also strengthen the supervision of the design of the type device, manufacture, use, make quality of product further be ensured and improve.The core component of fuel gas pressure-regulating box is gas pressure regulator, governor, is applicable to the gas of the different mediums such as rock gas, town gas, liquefied petroleum gas (LPG), mixed gas.
Model utility content
The purpose of this utility model is to provide a kind of compact gas pressure-regulating box at this; Structure is simple, compact, extensively can be useful in resident, section pressure regulation and change the boiler and burner air feed aspect of industrial and mining enterprise.
The utility model realizes like this, construct a kind of compact gas pressure-regulating box, it is characterized in that: comprise entrance sleeve, gas inlet ball valve, needle value A, filter, safety cut-off valve, signal tube, manually diffuse mouth, cut-out pressure adjustment cock, pressure governor, needle value B, gas outlet butterfly valve, discharge connection; Wherein gas inlet ball valve, needle value A, filter, safety cut-off valve, pressure governor, needle value B, gas outlet butterfly valve are formed and are communicated with, and entrance sleeve is communicated with gas inlet ball valve, and gas outlet butterfly valve is communicated with described discharge connection; Described entrance sleeve and discharge connection adopt following structure, and it comprises body and is placed in the fastening flange on body, and body bottom is welding shoulder, and loose flange is positioned on welding shoulder, and the end face of welding shoulder arranges sealing horse stable.
The utility model has the advantage of: compact gas pressure-regulating box described in the utility model; Structure is simple, compact, extensively can be useful in resident, section pressure regulation and change the boiler and burner air feed aspect of industrial and mining enterprise; Described fuel gas pressure-regulating box structural design is compact, and installation procedure is simple, and volume small footprint size is little; Guarantee user operation is simple and convenient, and suitable indoor or outdoor installation, maintenance is convenient.
