Problems solved by technology

[0003] However, the existing diaphragm gas meter has a flexible rubber part and the transmission mechanism is composed of plastic parts. It is difficult to guarantee the accuracy in the manufacturing process. By changing the gear sleeve that drives the counter, adjust the number of teeth and check with the gas meter standard Equipment calibration meets requirements
Due to the wide error distribution and the limited number of gears, there is a certain range and gear for adjusting the accuracy of the gas meter, so the accuracy is not enough

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0024] like figure 1 As shown, an intelligent counting gas meter includes a movement, and the movement includes a bellows 1, two membranes 2, a valve cover 3, a telescopic connecting rod 4, and a transmission disc 5. The two membranes 2 are installed in the membrane box 1, the valve cover 3 is installed on the membrane 2 and the movement of the membrane 2 drives the valve cover 3 to rotate, the transmission disc 5 is synchronously connected to the valve cover 3, and the telescopic connecting rod 4 is connected to the transmission disc 5 . Specifically, two metering chambers are formed in the bellows 1, and two membranes 2 are respectively located in the two metering chambers, and each membrane 2 separates the corresponding metering chamber to form two metering chambers,...

Abstract

The invention discloses an intelligent counting gas meter, and relates to the technical field of gas meters. The intelligent counting gas meter comprises a counting system, the counting system comprises a fixing frame, a positioning plate, a plurality of sampling sensors, a controller and a display, the plurality of sampling sensors are sequentially numbered anticlockwise or clockwise, the output ends of the plurality of sampling sensors are connected with the input end of the controller, and the output end of the controller is connected with the input end of the display. When a data processor sequentially receives single signals of the thirty sampling sensors according to the numbering sequence of the thirty sampling sensors, the controller counts the gas meter once and accumulatively displays the count on the display. When the data signals, received by the data processor, of the sampling sensors are incomplete or incorrect in sequence, the controller does not count the gas meter and drives an alarm to give an alarm, so that an operator is reminded to overhaul the gas meter, counting errors are reduced, and the technical precision of the gas meter is improved.

Description

technical field [0001] The invention relates to the technical field of gas meters, more specifically, it relates to an intelligent counting gas meter. Background technique [0002] The metering principle of the membrane gas meter is to use the pressure difference in the process of fluid flow as the driving force, so that the gas enters the metering chamber with a constant volume inside the core, and discharges it after it is full. The diaphragm feels the gas pressure and moves back and forth in the metering chamber. , so that the front and rear parts of the metering chamber are filled and discharged alternately. At the same time, the slide valve switches the air flow direction, pushes the diaphragm to swing back and forth, drives the connecting rod mechanism, and turns the swing of the diaphragm into the continuous rotation of the driving gear. The driving gear converts the cycle times of inflation and exhaust into The volume unit (usually m3) is finally displayed by the co...
