Abstract
The utility model provides a special frostless pressure-regulating cabinet for compressed natural gas. The utility model is composed of two pressure-reducing pressure-regulating device groups which are parallelly connected through pipelines, wherein each pressure-reducing pressure-regulating device group comprises a pressure-reducing pressure-regulating device, a low-pressure gauge, a high-pressure gauge, a high-pressure gas inlet stop valve and a low-pressure gas inlet stop valve, wherein the low-pressure gauge and the high-pressure gauge are connected with the pressure-reducing pressure-regulating device, and the high-pressure gas inlet stop valve and the low-pressure gas inlet stop valve are respectively connected with both ends of the pressure-reducing pressure-regulating device; each pressure-reducing pressure-regulating device is connected with a hot water inlet pipe and a hot water outlet pipe, wherein the hot water inlet pipe is provided with a hot water inlet stop valve, and the hot water inlet pipes and the hot water outlet pipes of the two pressure-reducing pressure-regulating device are respectively connected in parallel. The utility model can be provided with water from the outside to heat a low-pressure cavity of each pressure-reducing pressure-regulating device and provide heat energy required for expansion heat absorption when gas changes from high pressure to low pressure; the utility model can prevent frost formation and ice blocking in the process of pressure regulation and make pressure-regulating systems safely and stably work for a long time. The utility model is used for gas pressure regulation.
Description
Technical field
The utility model relates to a kind of gas surge tank, particularly relates to the special-purpose frostless surge tank of a kind of compressed natural gas.
Background technology
All need gases at high pressure are become low-pressure gas in many uses field, at present, generally adopt surge tank to carry out pressure regulation, in the pressure regulation process, because gas is understood swelling heat absorption when high pressure becomes low pressure, often cause in the pressure regulation process equipment frosting and ice stifled, thereby influence security, stability and the chronicity of pressure regulation process.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of frosting in use of former surge tank and stifled problem of ice of having solved, energy safety, the special-purpose frostless surge tank of compressed natural gas stable, that work over a long time.
The special-purpose frostless surge tank of the utility model compressed natural gas is by forming by pipeline and two decompression pressure regulator groups connecing.Each decompression pressure regulator group comprises the decompression pressure regulator, the low-pressure meter and the high pressure gauge that are connected with the decompression pressure regulator, the high pressure gas inlet shutoff valve and the low pressure gas outlet shutoff valve that are connected with decompression pressure regulator two ends, hot water inlet pipe and hot water outlet pipe with the decompression pressure regulator is connected are arranged on the hot water inlet stop valve on the hot water inlet pipe.The hot water inlet pipe of two decompression pressure regulators also connects the back and is connected with thermal source, and two hot water outlet pipes and connecing back are connected with externally drained pipe.Wherein, the decompression pressure regulator comprises shell, be arranged on the pressure regulating seat in the low-pressure cavity, be arranged on the pressure regulation pin on the pressure regulating seat, the pressure regulating seat briquetting that cooperates with pressure regulating seat, the pressure regulation bar that is connected with the pressure regulating seat briquetting, the low pressure gas discharge connection that is arranged on the shell and communicates with low-pressure cavity, the high pressure gas entrance sleeve that is arranged on the shell and communicates with high pressure chest is arranged on the hot water circulation chamber on the shell, is arranged on the shell and the hot water inlet pipe and the hot water outlet pipe that communicate with the hot water circulation chamber.The pressure regulation bar comprises pressure regulation transmission bar, is arranged on sealing gasket, pressure spring and adjusting pressuring handle on the pressure regulation transmission bar.
The principle of work of the special-purpose frostless surge tank of the utility model compressed natural gas is, has only one of them pressure regulator group work during work, another pressure regulator group is closed, during pressure regulation, regulate adjusting pressuring handle, select suitable low pressure, and unlatching high pressure gas inlet shutoff valve and low pressure gas outlet shutoff valve, open the hot water inlet stop valve simultaneously, high-pressure natural gas enters the pressure regulator high pressure chest by the high pressure gas entrance sleeve, entering low-pressure cavity by pressure regulation pin and pressure regulating seat briquetting expands, hot water in the hot water circulation chamber provides the gas swelling heat absorption required heat, low pressure natural gas after the expansion is discharged from the low pressure gas discharge connection, thereby finishes the pressure regulation process of rock gas from high pressure to low pressure
The advantage of the special-purpose frostless surge tank of the utility model compressed natural gas is owing to increased thermal source, the required heat of swelling heat absorption when gas is provided by high voltage variable low pressure, solve frosting and the stifled problem of ice in the pressure regulation process, for security of system, stable, long-term work provide assurance.
