[New patent introduction] A gas meter that automatically controls pressure and temperature

Today I will introduce a national invention authorized patent-a gas meter that automatically controls pressure and temperature. The patent was applied for by Chongqing Ruilibi Gas Equipment Co., Ltd., and the authorization was announced on March 9, 2018.

Content description

The invention relates to the field of gas meter equipment, in particular to a gas meter that automatically controls a gas meter based on pressure and temperature.

Background of the invention

At present, automatic control gas meters have become one of the indispensable equipment in gas equipment. With the continuous development of automatic control gas meters, automatic control gas meters are widely used due to their unique advantages, but some automatic control gas meters still exist Certain problems, the Chinese patent application number 2014102453444.9, the specific content is: a gas meter is disclosed, including an air inlet pipe, an air outlet pipe, a control module and at least one cavity, wherein: the inlet end of the cavity is connected The inlet pipe is equipped with an inlet valve, and the outlet end is connected to the outlet pipe and equipped with an outlet valve; a pressure sensor and a temperature sensor are installed inside the cavity; the pressure sensor measures the pressure in the cavity and transmits it to the control module; the temperature sensor collects the temperature in the cavity And transmit it to the control module; the control module controls the opening/closing of the inlet valve and the outlet valve according to the preset pressure and the received pressure to complete the air inlet and outlet process, and calculates the amount of material transferred at one time according to the preset pressure and the received temperature. The quantity of substances and the type of gas can be used to measure gas. The above-mentioned patents are inconvenient to use, unsafe to operate, and have poor stability. Therefore, a gas meter that automatically controls pressure and temperature is needed to solve the above problems.

Summary of the invention

In order to solve the above-mentioned problems, the present invention provides a gas meter that automatically controls gas based on pressure and temperature.

Figure is a structural view of the invention

In view of the above problems, the technical solution adopted by the present invention is: a gas meter that automatically controls pressure and temperature, including an outlet pipe, an inlet pipe, a pressure sensor, a flow pipe, and a temperature sensor. An inlet pipe is provided on one side of the outlet pipe, and the inlet pipe A pressure sensor is arranged on the lower side of the air pipe, a flow pipe is arranged around the pressure sensor, a temperature sensor is arranged under the flow pipe, a meter is arranged on one side of the temperature sensor, and an outer casing is arranged in front of the meter. A controller is arranged on one side, a display is arranged on one side of the controller, and a control button is arranged under the display.

In the above structure, when the outer casing is fixed and the control button is pressed, when the control button is pressed, the controller will issue a command, and then the intake pipe will enter the gas. When the gas enters, the pressure sensor will sense the pressure and temperature of the gas flow. The sensor will sense the temperature of the gas flowing in the flow pipe, and the meter will keep recording the gas flow, and then flow out through the gas outlet pipe, and finally show it on the display.

In order to further improve the quality of the automatic control gas meter, the outlet pipe is connected with the inlet pipe, the inlet pipe is connected with the pressure sensor, and the pressure sensor is connected with the flow pipe. The flow pipe is connected with the temperature sensor, the temperature sensor is connected with the meter, the meter is connected with the outer casing, and the outer casing is connected with the controller. The controller is connected with the display, and the display is connected with the control button through a signal line.

The beneficial effects of the invention are: accurate measurement of gas in the pipeline can be realized under different temperatures and different pressures, and the service life is long and the performance is stable.
