[0024] Figure 2 is the top view of the present invention;

[0025] Figure 3 is the schematic diagram of the vent pipe;

[0026] Figure 4 is the schematic diagram of the integrated instrument.

[0027] The working principle of the present invention is as follows:

[0028] 1. The gas in the pipe network enters the inlet pipe of the integrated IC magnetic card lobed impeller underground metering and billing box, flows through the IC magnetic card billing device after filtering, then enters the flowmeter, and flows out through the outlet pipe after metering and enters the subsequent pipeline.

[0030] 3. The breather valve and the relief valve on the side plate of the box body are connected to the vent pipe through a metal hose, so that the leaked gas or the gas for pressure relief during inspection and maintenance can enter the vent pipe through the metal hose and escape into the atmosphere. The breather valve is a one-way valve, which can make the leaked gas flow out of the box body while preventing the external air from flowing in, avoiding the formation of an air-gas mixture, reducing the potential explosion risk, and at the same time preventing the external humid air from flowing into the box body to keep the box body dry.

[0031] 4. An integrated instrument box is installed on the vent pipe, which can display the internal equipment parameters of the metering box in real time, and parameter query and IC magnetic card recharge can be carried out without opening the box cover. Specific implementation mode:

[0032] As shown in the figure: An integrated IC magnetic card rotary piston underground metering and charging box, the box body is buried underground, and the box body is composed of a lower box body 3, an upper box body 7 and an upper cover 14.

[0033] The box body is welded by steel plates, which is firm and durable. The external part is subjected to anti-corrosion treatment to ensure the quality and service life of the box body in the buried state. At the same time, it can shield external electromagnetic waves and reduce the interference to internal electronic equipment.

[0034] Reinforcing plate frames 11 that cross each other are welded on the upper cover 14 to increase the strength of the upper cover without increasing the weight; the upper cover is connected to the upper box body 7 through a hinge, and a sealing gasket 10 is filled at the closing contact along the upper edge of the upper box body 7, which can realize the functions of waterproofing and leakage prevention. A hollow cylindrical lock sleeve 12 is welded on the upper cover 14, and a screw is inserted in the middle to realize the locking with the upper box body. The lock hole of the upper cover can be screwed into a plug with an O-ring to realize the waterproof function of the upper cover lock, and the plug can be a non-standard plug such as an internal octagonal plug to increase the difficulty of unlocking, or a special lock can be installed for easy management. A handle 13 is installed at the edge of the upper cover 14 to facilitate opening the cover.

[0035] A window is installed in the upper box body. The window is composed of a window frame 9 and a window plate 15 installed on it. A handle is installed on the window plate for easy lifting. The window frame can be conveniently connected and fixed to the upper box body 7 through a butterfly nut. A sealing strip 16 is installed at the lower part of the frame and cooperates with the upper box body 7 to realize the functions of sealing and leakage prevention. At the same time, it can prevent water, dust and sundries from entering the equipment and ensure the normal operation of the equipment. The window plate can be made of transparent tempered glass or polycarbonate plate, which is light in weight and large in strength. The parameters of the flowmeter head and the working state of the equipment can be observed without removing the window, which is convenient for inspection.

[0036] A sealing gasket 21 is installed at the connection between the lower box body 3 and the upper box body 7 to realize the sealing between the upper and lower box bodies.

[0037] An inlet valve 32 and an inlet pipe, an outlet valve 35 and an outlet pipe are welded on the lower box body 3. A partition plate 27 is welded inside the lower box body 3 to divide the lower box body into an inlet chamber and an outlet chamber. The inlet chamber is mainly an equipment installation area, and the outlet chamber is connected to the outlet pipe.

[0038] Reinforcing plates 23 are welded at the connection between the inlet and outlet pipes and the lower box body 3 to increase the connection strength between the inlet and outlet pipes and the lower box body, and prevent accidents such as the weld being pulled off due to the ground settlement causing the pipeline to be suspended and increasing the tensile force on the weld.

[0039] The connection point between the lower box body 3 and the upper box body 7 is fixedly connected with a connecting disc 6 through bolts. An O-ring 20 is installed in the middle to achieve the seal between the connecting disc and the lower box body 7. Hoisting rings 19 are installed at both ends of the connecting disc.

[0040] On the upper part of the connecting disc 6, there is a flange seat. On the flange seat, there are a lobed wheel flowmeter 31 and an IC magnetic card charging device 36. The inlet of the lobed wheel flowmeter and the outlet of the IC magnetic card charging device are connected through a communicating pipe 33. At the same time, the meter head 30 of the lobed wheel flowmeter and the IC magnetic card charging device 36 are connected through a signal pipe 37 for real-time charging. A sleeve and a filter element are installed under the connecting disc. A valve barrel 2 is inserted into the sleeve and sealed with an O-ring seal 22. A gasket 1 is sandwiched between the valve barrel and the partition plate 27. The elastic force applied by a spring 24 installed on the valve barrel 2 enables the valve barrel to press the gasket 1 to achieve sealing.

[0041] A fastening plate 25 is installed between the bottom end of the filter element 5 and the valve barrel 2. The fastening plate is fixed and clamped to the filter element through a fastening screw 4 installed on the connecting disc, and at the same time, the spring 24 is pre-tightened. The fastening plate 25 and the valve barrel 2 are sealed with an O-ring seal 26, enabling the gas coming in from the inlet to be completely filtered.

[0042] A differential pressure gauge 38 is installed on the connecting disc 6, which can effectively display the pressure difference inside and outside the filter element to reflect the degree of blockage of the filter element, so as to clean and replace it in time.

[0043] A breathing valve 8 is installed on the upper box body 7. The breathing valve is a one-way valve, which can ensure that when the viewing window is not tightly installed and the internal equipment leaks, the gas can pass through the breathing valve and the connected metal hose into the vent pipe in time for venting, eliminating the hidden danger that the upper cover bears the internal gas pressure due to internal leakage and the gas sprays out when the upper cover is opened during inspection and maintenance; using a one-way valve can make the leaked gas flow out of the box body while the external air cannot flow in, avoiding the formation of an air-gas mixture, reducing the potential explosion risk, and at the same time playing a role in preventing the entry of external humid air.

[0044] A signal pipe interface 28 is installed on the upper box body 7. The IC magnetic card charging device 36 and the electronic meter head 30 of the lobed wheel flowmeter are connected through an internal signal pipe 37, and the electronic meter head is connected to an external instrument box 42 through a remote signal pipe 29 and the signal pipe interface 28 to achieve the remote transmission function for real-time charging. When the balance is insufficient, the gas supply can be automatically cut off, and the gas supply can be automatically restored after recharging. The recharge operation can be carried out on the IC magnetic card charging device or in the external instrument box.

[0045] A venting interface 34 is installed on the upper box body 7. The venting connecting pipe 18 is connected to the external vent pipe 44 through the venting interface 34. By opening the venting valve 17, the gas in the pipeline can be depressurized and discharged into the vent pipe. The vent pipe 44 is 4 meters above the ground, and the discharged gas is dispersed into the high-altitude atmosphere to ensure safety. An instrument box 42 is installed in the middle of the vent pipe 44, and a vent pipe cap 41 is installed on the upper part to prevent rainwater from entering the vent pipe. An interface 43 is installed on the lower part, which can be connected to a metal connecting pipe to realize the introduction of gas and signal pipelines. An integrated instrument 36 is installed in the instrument box 42. The integrated instrument can display the device parameters such as the turbine flowmeter and the IC magnetic card charging device in real time, and the IC magnetic card can be recharged through the integrated instrument without opening the metering box cover, which is convenient for operation. A box lock 45 is installed on the instrument box for easy management.

[0046] A spare interface 40 is installed on the upper box body 7 for use when the function is expanded.

[0047] The integrated instrument has the following characteristics:

[0048] 1. The internal integrated electronic instrument is of an integral type, which can connect multiple signals, such as temperature, pressure, flow and other signals, and can be displayed on the liquid crystal screen in real time;

[0049] 2. The recording frequency can be set and the recorded parameters can be stored, and the operation records can be stored.
