Description

Technical Field

[0001] The utility model relates to the technical field of gas metering, in particular to a gas metering device which is easy to install. Background Art

[0002] As a gas metering device, gas meter originated in Europe in the 19th century. Its emergence and development are closely related to gas use and industrial technology changes. Gas meter is an important part of the gas system and has a great impact on the safe operation, service quality, economic benefits, etc. of gas companies. With the development of the economy and society and the implementation of the natural gas tiered price policy, the problems faced by gas companies in the new era, such as home meter reading, security inspection, supervision, price adjustment, settlement, accidents, etc., are becoming increasingly prominent.

[0003] Today's gas meters are relatively mature. Commonly used gas meters include not only traditional gas meters, but also some smart gas meters are also widely used. However, there are still problems with the installation of gas meters. This is due to the different installation environments. Not only that, the installation and disassembly steps of gas meters are also relatively cumbersome.

[0004] As the gas meter is used for a longer time, the aging of its components is inevitable, which poses a great risk to the use of gas. Nowadays, most of the components of gas meters are metal components, which means that in a humid environment, the components are easily corroded, resulting in inaccurate measurement and even gas leaks. Utility Model Content

[0005] The utility model aims to provide a gas metering device that is easy to install, so as to solve the problems in the above-mentioned background technology that the disassembly and assembly steps are relatively complicated and the parts are prone to aging.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a gas metering device that is easy to install, comprising a shell and a positioning block, the inner convex surface of the shell is fixedly connected to a gas pipeline, a ball valve is installed in the middle of the gas pipeline, a meter is installed at the upper end of the gas pipeline, nuts are installed on both sides of the gas pipeline, a connecting bracket is connected to the side of the nut, and the connecting bracket

[0007] 1. During installation, insert the gas pipe into the holes on both sides of the shell, and then rotate the rotating rod until the gas pipe is connected and tightened with the gas pipe. During disassembly, rotate the rotating rod in the opposite direction until the gas pipe is disconnected from the gas pipe to complete the disassembly. Since the meter is installed on the upper surface of the gas pipe, and the gas pipe is fixedly connected to the shell, and a nut is installed on the gas pipe, the meter can be disassembled and assembled by disconnecting or tightening the nut from the gas pipe. No tools are needed, which optimizes the cumbersome process and makes disassembly and assembly more convenient.

[0008] 2. When the humidity inside the device is too high, the water-absorbing resin inside the button will expand when it comes into contact with water, so that the piston moves downward, causing the positioning block to move downward, the limit block to pop out, and the baffle to rotate, increasing air flow to reduce humidity and prevent aging of components;

[0009] 3. When a fault occurs and maintenance is required, press the button to move the positioning block downward, so that the spring inside the positioning slot is deformed, and the limit block pops out, the baffle rotates, and the internal components can be seen. Close the ball valve to disconnect the gas, which facilitates maintenance for the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-6The utility model provides a technical solution: a gas metering device that is easy to install, including a shell 1, a gas pipe 2, a ball valve 3, a meter 4, a nut 5, a connecting bracket 6, a rotating rod 7, a block 8, a threaded rod 9, a button 10, a piston 11, a positioning groove 12, a positioning block 13, a baffle 14, a rotating shaft 15 and a limiting block 16. The inner convex surface of the shell 1 is fixedly connected with the gas pipe 2, the middle position of the gas pipe 2 is installed with a ball valve 3, the upper end of the gas pipe 2 is installed with a meter 4, nuts 5 are installed on both sides of the gas pipe 2, and the side of the nut 5 is connected with a connecting bracket 6, the upper surface of the connecting bracket 6 is provided with a rotating rod 7, the inner wall top surface of the connecting bracket 6 is provided with a block 8, the lower surface of the block 8 is fixedly connected to the upper end of the threaded rod 9, the lower end of the threaded rod 9 passes through the shell 1, the gas pipe 2 and the ball valve 3 are rotatably connected, the gas pipe 2 and The nut 5 is a rotational connection, and the nut 5 and the connecting bracket 6 are meshingly connected. The outer surface of the nut 5 is evenly distributed with teeth. The rotating rod 7 and the stopper 8 are fixedly connected through the rectangular hole of the connecting bracket 6. One side surface of the connecting bracket 6 is evenly distributed with teeth. During installation, the gas pipe is inserted into the holes on both sides of the shell 1. At this time, the rotating rod 7 is rotated. Due to the rotation of the rotating rod 7, the threaded rod 9 fixedly connected to the stopper 8 is rotated, so that the threaded rod 9 moves downward through the thread of the shell 1. Since the rotating rod 7 also moves downward at the same time, the connecting bracket 6 is pressed downward, and the nut 5 meshingly connected with the connecting bracket 6 is rotated until the gas pipeline and the gas pipe 2 are fastened. At this time, the installation is completed. During disassembly, the rotating rod 7 is rotated in the opposite direction, and the stopper 8 moves upward, thereby pressing the connecting bracket 6 upward until the nut 5 is disconnected from the gas pipe 2. At this time, the disassembly is completed.

[0019] A button 10 is installed at the upper end of the shell 1, and a piston 11 is arranged inside the button 10. A positioning groove 12 is fixedly installed on the upper end of the shell 1, and a limiting block 16 is fixedly installed at the bottom of the button 10 and is located below the positioning groove 12. The positioning block 13 is fixedly installed on the upper end surface of the baffle 14, and a rotating shaft 15 is installed inside the lower end of the baffle 14. The button 10 is slidably connected to the piston 11, and a spring is installed at the bottom of the piston 11. A spring is arranged inside the positioning groove 12, and the baffle 14 is rotatably connected to the shell 1. The end of the positioning block 13 is a right-angled trapezoidal block protrusion, and the limiting block 16 is hook-shaped as a whole. When maintenance is needed, press the button 10 and the limiting block 16 is hooked. As the button 10 descends, the limit block 16 also descends. Since the locking block 13 loses the support of the limit block 16, the spring inside the locking groove 12 recovers its shape, popping out the locking block 13, and the baffle 14 rotates due to gravity. The baffle 14 opens, and the internal structure can be seen at this time, which is convenient for maintenance. When the humidity is too high, the water-absorbing resin contained in the button 10 will expand when it meets water. At this time, the piston 11 moves downward due to the expansion and compression, which is the same as the working principle when the button 10 is pressed, so that the baffle 14 is opened, and air can flow into the interior of the shell 1 to take away excess moisture to ensure dryness, thereby preventing parts from rusting and aging due to moisture.

[0020] Working principle: When using the easy-to-install gas metering device, the nut 5, connecting bracket 6, button 10, and positioning block 13 and other structures are used. When installing, you only need to rotate the rotating rod 7 to complete the installation. When the humidity is too high, the baffle 14 will automatically pop open to improve air circulation. When this device is in use, the gas will enter the inside of the gas pipe 2 through the gas pipe connected to the outside, and then the gas will complete the metering work through the inside of the meter 4. The meter 4 is a mature mechanical product commonly used on the market. It records the gas volume, and finally the gas is discharged from the end of the gas pipe 2 to the gas pipeline on the other side.
