It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined or illustrated in one figure, it will not need to be further discussed or illustrated in detail in the description of the following figure.

As shown in fig. 1-3, the present invention provides a technical solution: the utility model provides a gas pressure regulating temperature pressure correction batch meter, includes measurement box 1, needs to notice that measurement box 1 need be placed outdoors, exposes in external environment for a long time, consequently measures box 1 and need once only cast the shaping, and the gap is not stayed to the outside, avoids rainwater infiltration measurement box 1 inside. In this embodiment, the metering box 1 is made of austenitic stainless steel to improve the corrosion resistance of the metering box 1 facing the external environment, and ensure that the metering box 1 can provide protection for the internal mechanism of the box in a long period of time. At the same time, austenitic stainless steel is almost non-magnetic and therefore does not interfere with the various compact electronics inside the metering box 1. The inside fixedly connected with pressure regulating valve body 12 of metering tank 1, pressure regulating valve body 12 outside is including logical valve top cap 1201 and logical valve end box 1210, and in this embodiment, logical valve top cap 1201 and logical valve end box 1210 pass through bolt fixed connection to form inclosed space between the two and regard as the passageway of gas, consequently logical valve end box 1210 one side fixedly connected with gas filling pipe 1205, logical valve end box 1210 opposite side fixedly connected with gas output tube 1209. The top end of the through valve top cover 1201 is provided with an upper sliding port and a lower sliding port, the transmission ejector rod 1206 penetrates through the through valve top cover 1201, and meanwhile, a sealing washer and a washer protective shell are arranged at the joint of the transmission ejector rod 1206 and the through valve top cover 1201, so that when the transmission ejector rod 1206 slides up and down in the sliding ports, the whole air tightness of the pressure regulating valve body 12 is not damaged, and gas leakage is prevented. The bottom end of the transmission ejector rod 1206 is fixedly connected with a sensitive spring 1202, and the bottom end of the sensitive spring 1202 is fixedly connected with a sealing membrane 1207. In this embodiment, a sealing notch is formed in the side direction of the connection surface of the through valve top cover 1201 and the through valve bottom case 1210, and the sealing film 1207 is being clamped in the sealing notch to divide the interior of the pressure regulating valve body 12 into two airtight halves. When the pressure of the injected gas is too high, the excessive gas is injected into the pressure regulating valve body 12 and cannot be discharged through the gas output pipe 1209, the air pressure in the space below the sealing membrane 1207 is increased, the sealing membrane 1207 is upwards supported, and the sensitive spring 1202 and the transmission ejector rod 1206 above the sealing membrane 1207 are driven to ascend. Sealing involucra 1207 bottom fixedly connected with drive post 1208, drive post 1208 bottom swing joint has loose axle 1203, and gas control pipe 1204 has been placed to loose axle 1203 bottom, and it should be noted that, in this embodiment, gas control pipe 1204 one end and gas filling pipe 1205 directly communicate, but the other end is sealed, has only seted up the intercommunicating pore at the top, releases the gas to pressure regulating valve body 12 in through this intercommunicating pore. And the bottom end of the movable shaft 1203 is provided with a blocking column, the section of the blocking column is matched with the communicating hole, and when the movable shaft 1203 is laid flat, the blocking column just blocks the communicating hole. When the sealing membrane 1207 is in a relaxed state, the driving column 1208 is in a lower position, one end of the movable shaft 1203 is pressed by the driving column 1208 to sink, and the other end of the movable shaft 1203 tilts up, so that the blocking column is separated from the communicating hole; when the seal film 1207 expands upward, one end of the movable shaft 1203 rises and the other end thereof descends, so that the plug is inserted into the communication hole, thereby preventing the gas from being continuously injected, reducing the air pressure in the pressure regulating valve body 12, and returning the seal film 1207. The top end of the transmission ejector rod 1206 is fixedly connected with a pressure sensor 7, and the top end of the pressure sensor 7 is fixedly connected with a sensor fixing frame 8. The pressure sensor 7 judges the air pressure in the pressure regulating valve body 12 by sensing the rising force of the transmission ejector rod 1206, and converts the air pressure into an electric signal to be transmitted. The top end of the top cover 1201 of the through valve is fixedly connected with a pressure gauge 13 which can visually reflect gas pressure. The top end of the top cover 1201 of the through valve is fixedly connected with a temperature sensor 11 for sensing the temperature of the fuel gas, so that accidents caused by high temperature are avoided, and a thermometer is arranged on one side of the temperature sensor 11. The top end of the metering box body 1 is fixedly connected with a buzzer 2, and the top end of the metering box body 1 is fixedly connected with a flash lamp 3; measurement box 1 one side swing joint has

switch door

6, and 6 one sides fixedly connected with operating panel 4 of switch door, 4 top fixedly connected with display screens 5 of operating panel, the inside signal of telecommunication conduction to operating panel 4 that produces of temperature sensor 11 and pressure sensor 7 to feed back to in the display screen 5. The inboard fixedly connected with gas concentration converter 9 of measurement box 1, gas concentration converter 9 bottom fixedly connected with gas retort 10, in this embodiment, placed the material that can adsorb the gas molecule in the gas retort 10, in the adsorption process, the electrochemical property of adsorbed material changes, and is provided with sampling circuit among the gas concentration converter 9, and has the electrode to expose in gas retort 10 among the sampling circuit. The change of the electrochemical property of the adsorption substance causes the change of the current in the sampling circuit, so that the change of the gas concentration is converted into an electric signal to be transmitted to the operation panel 4, when the operation panel 4 judges that the parameters in the gas pipeline are abnormal, the buzzer 2 and the flash lamp 3 can be started to give an alarm, and the alarm is remotely informed to a worker. In this embodiment, a ceiling may be provided on the top of the metering box 1 to protect the buzzer 2 and the flash lamp 3.

To use the present embodiment, the metering box 1 and the gas piping system are first connected, and normal gas pressure, temperature and concentration are input to the operation panel 4. When the difference between the signals transmitted from the pressure sensor 7, the temperature sensor 11 and the gas concentration converter 9 and the set value is too large, the operation panel 4 starts the buzzer 2 and the flash lamp 3 to remind surrounding people of paying attention, and remotely informs workers of overhauling, and during overhauling, the numerical value can be visually reflected through the pressure gauge 13 and the thermometer without looking up the display screen 5.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
