Description

Technical Field

[0001] The utility model belongs to the technical field of metering, and in particular relates to a device for metering the flow of annular gas. Background Art

[0002] Flowmeters are necessary metering equipment in natural gas pipeline systems. For a long time, common flowmeters in natural gas pipeline systems have been turbine flowmeters and orifice flowmeters. Mechanical metering equipment has a complex structure and is prone to blockage of its flow channel or corrosion of its parts due to water vapor and particulate debris carried in natural gas, which not only reduces the service life of the flowmeter, but is also extremely detrimental to accurate measurement.

[0003] After searching, in the related technology, the patent document with the authorization publication number CN208350165U discloses a device for gas metering, including a flap and a main body, the flap is a triangular structure, the bottom end of the flap is provided with two symmetrical gas bins, the two gas bins are separated by the middle gas dividing baffle, the top of the flap is provided with a shielding protrusion, and the middle part of the lower end of the flap is provided with an axial hole; the bottom end of the main body is provided with an air hole, the air hole passes through the bottom end of the main body to communicate with the inside of the main body, the side wall of the bottom end of the air hole is provided with an axial fixing hole, and the flap shaft passes through the axial fixing hole and the axial hole to movably install the flap in the main body. The utility model has a simple structure and is easy to use. The drainage method is used to calculate the volume of gas passing through. There is a triangular flap inside the main body, which has two symmetrical gas bins. After the gas flows through the gas bin, the gas bin flips, and the shielding protrusion also flips, which can be counted once, and then the gas bin on the other side flips, counts again, and repeats in sequence; it is convenient for operators to quickly measure the volume of gas, and it has strong practicality.

[0004] Regarding the above-mentioned related technologies, the utility model applicant believes that there are the following defects:

[0005] 1. Although the above device uses the drainage method to calculate the volume of gas passing through, there is a triangular flap inside the main body, which has two symmetrical gas chambers. After the gas flows through the gas chamber, the gas chamber flips, and the shielding protrusion also flips, which can be counted once, and then the gas chamber on the other side flips, and counts again, and the cycle continues. However, this technology requires personnel to keep staring at the triangular flap to flip and count, so over time, it is easy to cause eye fatigue, dizziness, and wrong counting, so the accuracy is poor.

[0006] Therefore, it is necessary to provide a new device for measuring the annular gas flow to solve the above technical problems. Utility Model Content

[0009] The two connection sealing components are respectively arranged on pipe one and pipe two, and the connection sealing components include a connection sleeve, a sealing ring one and a sealing ring two. The connection sleeve is fixedly installed on pipe one, the sealing ring one is arranged on pipe one and matched with the connection sleeve, and the sealing ring two is arranged on the connection sleeve.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 The structure of the utility model is shown in FIG. Figure 1 ; Figure 2 The structure of the utility model is shown in FIG. Figure 2 ; Figure 3 for Figure 1 The enlarged structural diagram of part A in the figure. The device for measuring the flow of the ring gas comprises: an integrated flow meter 1, a pipe 1 2, a pipe 2 3 and two connecting sealing components, wherein the pipe 1 2 and the pipe 2 3 are respectively adapted to the water inlet and the water outlet of the integrated flow meter 1;

[0023] The two connecting sealing components are respectively arranged on pipe 1 2 and pipe 2 3, and the connecting sealing components include a connecting sleeve 4, a sealing ring 1 5 and a sealing ring 2 6. The connecting sleeve 4 is fixedly installed on pipe 1 2, the sealing ring 1 5 is arranged on pipe 1 2 and is adapted to the connecting sleeve 4, and the sealing ring 2 6 is arranged on the connecting sleeve 4.

[0024] The two sealing rings 1 5 are respectively matched with the water inlet and the water outlet of the integrated flow meter 1 , and the inner walls of the two sealing rings 2 6 are respectively matched with the outer walls of the water inlet and the water outlet of the integrated flow meter 1 .

[0025] The two connecting sleeves 4 are connected and fixed by a plurality of fixing components, wherein the fixing components include an L-shaped fixing rod 7 , a fixing block 8 , a nut 9 and a handle 10 . The L-shaped fixing rod 7 is fixedly mounted on the corresponding connecting sleeve 4 .

[0026] The fixing block 8 is fixedly mounted on the corresponding connecting sleeve 4 , and one end of the L-shaped fixing rod 7 passes through the fixing block 8 and is slidably connected to the fixing block 8 .

[0027] The L-shaped fixing rod 7 is connected and fixed to the fixing block 8 via a nut 9 , and the handle 10 is fixedly mounted on the nut 9 .

[0028] The fixing block 8 is provided with a sliding hole, and the sliding hole is adapted to the L-shaped fixing rod 7 .

[0029] The working principle of the device for measuring the flow of annular gas provided by the utility model is as follows:

[0030] The first step: when in use, the water inlet of the integrated flow meter 1 is inserted into the connecting sleeve 4 and contacts with the sealing ring 1 5. During this period, the sealing ring 2 6 is sleeved on the outer wall of the water inlet of the integrated flow meter 1. Therefore, the sealing ring 1 5 is tightly fitted with the water inlet of the integrated flow meter 1, and the sealing ring 2 6 is tightly fitted on the outer wall of the water inlet of the integrated flow meter 1, thereby ensuring the sealing performance, thereby preventing water leakage. Similarly, the pipe 2 3 is connected to the water outlet of the integrated flow meter 1, and the integrated flow meter 1 can measure the gas flow through the integrated flow meter 1 (the integrated flow meter 1 is a finished product of the prior art, so the specific structure and if it is measured will not be described in detail). This model is a 3095MV flow transmitter, which has the technical characteristics of fast measurement, dynamic calculation, and no memory occupation of the intelligent terminal, so the performance-price ratio is high, and there is no need to stare at the counting, thereby improving the accuracy;

[0031] The second step: during the connection process, the L-shaped fixed rod 7 will pass through the sliding hole on the fixed block 8, and then the L-shaped fixed rod 7 will be fixedly connected to the fixed block 8 by the nut 9, thereby ensuring that the pipe 1 2 and the pipe 2 3 are tightly fitted with the water inlet and outlet of the integrated flow meter 1, thereby improving the sealing performance. Similarly, the nut 9 can be removed by rotating the handle 10, and then the integrated flow meter 1 can be separated from the pipe 1 2 and the pipe 2 3 to complete the disassembly.
