[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: including an ultrasonic flow meter assembly 1, wherein gas leakage prevention components 2 are provided on both sides of the ultrasonic flow meter assembly 1.

[0024] The gas leakage prevention assembly 2 includes a first housing 201, a second housing 202 on one side of the first housing 201, a second retaining ring 204 fixedly installed on both the front and back of the first housing 201, a first retaining ring 203 fixedly installed on both the front and back of the second housing 202, and a detection tube 205 fixedly inserted into one side of the second housing 202. A sealing cap 206 is threaded onto one end of the detection tube 205. To prevent gas leakage at the flange joint 104 from causing inaccurate measurement data, the sealing cap 206 can be opened periodically, and then the corresponding gas detector can be taken out and inserted into the detection tube 205. After insertion, the inside of the sleeve can be detected. If there is a gas leak, it can be detected, thus indicating that a gas leak has occurred at the flange joint 104.

[0025] In this embodiment, the ultrasonic flowmeter assembly 1 includes a flowmeter housing 101. An integrator 102 is fixedly installed on the top of the flowmeter housing 101. The flow integrator controller processes various signals such as temperature, pressure, and flow rate for acquisition, display, control, remote transmission, communication, and printing, forming a digital acquisition and control system. It features LCD and digital displays, various external dimensions, and is suitable for flow integrator measurement and control of various liquids, general gases, superheated steam, and saturated steam. It can perform quantitative / batch control of the medium (with start, stop, and zeroing functions), and is used with various flow sensors or transmitters, adapting to various measurement and control applications. Vent pipes 103 are provided on both sides of the flowmeter housing 101. A flange joint 104 is fixedly sleeved on one end of each vent pipe 103. One side of the flange joint 104 has a... Several threaded ports 105 are used to connect the flow meter to the middle of the gas pipeline via flange joints 104 at both ends of the flow meter. Specifically, the flange joints 104 are connected to the flange joints 104 of the gas pipeline. After the connection is made, the first clamping ring 203 and the second clamping ring 204 are connected and wrapped around the vent pipe 103. After wrapping, the clamp 207 is put on the pipe body of the vent pipe 103. The clamp 207 is used to merge the first sleeve 201 and the second sleeve 202 together. After the first sleeve 201 and the second sleeve 202 wrap around the flange joints 104, the first sleeve 201 and the second sleeve 202 can form a sleeve. The sleeve wraps around the two flange joints 104 and provides an external protection function. The sleeve can prevent gas from leaking directly when there is a leak at the flange joints 104, thus improving safety.

[0026] Meanwhile, a clamp 207 is fitted on the outer side of the first clamping ring 203 and the second clamping ring 204. Both ends of the clamp 207 are fixedly installed with mating plates 208. The two mating plates 208 are directly opposite each other and fit together. Locking screws 209 are threaded into the sides of the two mating plates 208. One end of the locking screw 209 is threaded through the two mating plates 208, and a nut 210 is threaded onto the end of the locking screw 209 that passes through the two mating plates 208. This allows the two ends of the clamp 207 to be joined together, thereby tightening the clamps of the first clamping ring 203 and the second clamping ring 204.

[0027] The second casing 202 has a first sealing groove 211 on both ends, and a first sealing strip 212 is fixedly installed on both ends of the first casing 201. The first sealing strip 212 is inserted into the first sealing groove 211, which can improve the connection and sealing performance between the first casing 201 and the second casing 202.

[0028] The second ferrule 204 is fixedly installed with a second sealing strip 214 on both ends. The first ferrule 203 is provided with a second sealing groove 213 on both ends. The second sealing strip 214 is movably inserted into the second sealing groove 213, which can effectively improve the sealing performance of the first ferrule 203 and the second ferrule 204.

[0029] The first retaining ring 203 and the second retaining ring 204 together form a retaining ring, which is fitted onto the pipe body of the vent pipe 103. The flange joint 104 is located inside the first sleeve 201 and the second sleeve 202, which together form a sleeve.

[0030] In summary, this modular ultrasonic gas flow meter provides external protection by installing sleeves at both ends of the connector. The sleeves prevent direct gas leakage in the event of a leak at flange connector 104, thus improving safety. Furthermore, the sleeves facilitate the inspection of gas leaks at both ends of the modular ultrasonic gas flow meter, enhancing the test accuracy and practicality of the flow meter.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
