Description

Technical Field

[0001] The utility model relates to the technical field of gas equipment, in particular to a combined structure of a valve and a pipe. Background Art

[0002] In the field of gas equipment, the combination of valves and pipes is a key component of gas transportation. The traditional combination of valves and pipes usually uses copper pipes as ventilation pipes. Although copper pipes have good electrical and thermal conductivity, their cost is relatively high. Specifically, on the one hand, the material cost of copper pipes is expensive; on the other hand, the process is complicated, and the labor and production costs are high. During the production process, after the copper pipes are processed and welded with brass joints and other joint structures, they will oxidize due to high temperature. After the copper pipes are oxidized, they need to be treated with pickling liquid, which increases the cost, and the waste pickling liquid after use is easy to cause pollution.

[0003] For example, a Chinese patent with the patent number CN202020948683.4 discloses a new type of stove, including support legs, a fuel box and a fire hood, wherein the support legs are provided in three groups, and the support legs are arranged at equal angles outside the fixing ring and fixed, the fixing ring is fixedly connected to the bottom of the fuel box through a support plate, the inside of the fuel box is connected to the ferrule through a pipeline, the ferrule is connected to the control valve through a copper tube, the control valve is fixedly mounted on the valve seat, and the valve seat is fixed to the fixing ring by welding. However, the new stove connects the copper tube to the control valve through the ferrule, so the combined structure of the valve and the tube has high production costs, which is not conducive to the market promotion of gas equipment. Utility Model Content

[0004] The utility model aims to overcome the problems of the prior art and provides a combined structure of a valve and a pipe.

[0007] Furthermore, the ventilation aluminum tube is a bendable 3003 aluminum tube.

[0008] Furthermore, the outer diameter of the ventilation aluminum tube is 3.2 mm; the wall thickness of the aluminum tube is 0.6 mm.

[0009] Furthermore, the ventilation aluminum tube and the valve body are connected via a tube clamp.

[0010] Furthermore, the pipe clamp includes a locking pipe seat, a pipe cover plate and screws; the locking pipe seat is connected to the valve body at a position corresponding to the air inlet; one end of the ventilation aluminum tube passes through the pipe cover plate and is adapted to be embedded in the locking pipe seat and is connected to the air inlet; the pipe cover plate is connected to the locking pipe seat by screws to fix the ventilation aluminum tube on the valve body.

[0011] Furthermore, the other end of the ventilation aluminum tube is connected to the brass joint by crimping or welding.

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figure 1 to Figure 2 As shown, a valve and pipe combination structure includes a valve body 1; the valve body 1 has an air inlet connected to the inner cavity of the valve body 1; the valve and pipe combination structure also includes a ventilation aluminum tube 2; one end of the ventilation aluminum tube 2 is connected to the valve body 1 and connected to the air inlet. The ventilation aluminum tube 2 is used to replace the copper tube, which simplifies the production process, is easy to process, reduces manual operations, and improves production efficiency. The price of aluminum is relatively low, which can effectively reduce production costs in terms of simplifying production processes and materials, and help improve the market competitiveness of gas equipment; and the impact on the environment during production and use is small, which helps to achieve green production and sustainable development, thereby improving environmental protection performance; and by setting the valve body 1 and the ventilation aluminum tube 2 in combination, the ventilation aluminum tube 2 is used to replace the traditional copper tube, so that the structure is lightweight, and the density of aluminum is much lower than that of copper. Therefore, the aluminum tube of the same volume is lighter than the copper tube, which is conducive to reducing the weight of the entire fluid control system and is convenient for installation and transportation. The other end of the ventilation aluminum tube 2 is connected with a brass joint 3. The design of the brass joint 3 enables the aluminum pipe to be reliably connected to other pipes or equipment, while improving the sealing performance of the connection.

[0027] In this embodiment, the outer diameter of the ventilation aluminum tube 2 is 3-3.5 mm, preferably 3.2 mm; the wall thickness of the aluminum tube is 0.5-0.7 mm, preferably 0.6 mm. The outer diameter and wall thickness of the ventilation aluminum tube 2 are controlled within a set range. Such a size design ensures that the ventilation aluminum tube 2 has sufficient strength to withstand the pressure of the internal gas, and can remain light and flexible, easy to install and connect, and reduces material costs.

[0028] Preferably, the ventilating aluminum tube 2 is a bendable 3003 aluminum tube. The ventilating aluminum tube 2 is designed in this way. First, the bendability makes the 3003 aluminum tube more flexible and convenient during the installation process. Compared with traditional rigid pipes, the bendable ventilating aluminum tube 2 can easily adapt to various complex installation environments, reducing the difficulty and cost of installation. Whether it is bending, twisting or bypassing obstacles, this ventilating aluminum tube 2 can easily cope with it, greatly improving the installation efficiency. Secondly, the bendable ventilating aluminum tube 2 has good corrosion resistance. Gas equipment is often in a humid or corrosive environment, so the corrosion resistance of the pipeline is very important. The surface of the 3003 aluminum tube is specially treated to effectively resist oxidation and corrosion and extend the service life of the pipeline. In addition, the bendable aluminum tube also has high strength and stability. Although it has the characteristics of bendability, it performs well when under pressure and is not easy to deform or break. This stability ensures the safety and reliability of gas equipment during operation and reduces the safety risks caused by pipeline problems. Finally, the bendable aluminum tube also has the advantages of environmental protection and energy saving. Aluminum itself has good recyclability, and the use of bendable ventilation aluminum tube 2 is conducive to reducing resource waste and environmental pollution. At the same time, due to its excellent performance, it can reduce energy waste caused by pipeline damage, thereby achieving the goal of energy conservation and emission reduction. In summary, the bendable 3003 aluminum tube has many advantages in the field of gas equipment, including flexible and convenient installation, strong corrosion resistance, high strength and good stability, and environmental protection and energy saving. Of course, the ventilation aluminum tube 2 is not limited to 3003 aluminum tube, and can also be replaced by 1060 aluminum tube or 6063 aluminum tube and other models.

[0029] In order to facilitate the stable connection between the ventilation aluminum tube 2 and the valve body 1 and facilitate disassembly and assembly, the ventilation aluminum tube 2 and the valve body 1 are connected by a pipe clamp 4. Preferably, the pipe clamp 4 includes a locking tube seat 41, a tube cover plate 42 and a screw 43; the locking tube seat 41 is connected to the valve body 1 at the position corresponding to the air inlet; one end of the ventilation aluminum tube 2 passes through the tube cover plate 42 and is adapted to be embedded in the locking tube seat 41, and is connected to the air inlet; the tube cover plate 42 is connected to the locking tube seat 41 by a screw 43 to fix the ventilation aluminum tube 2 on the valve body 1. Of course, in other embodiments, the ventilation aluminum tube 2 and the air inlet of the valve body 1 can be connected by welding, threaded connection, etc. to ensure the connection strength and sealing.

[0030] In this embodiment, the other end of the ventilation aluminum tube 2 is connected to the brass joint 3 by crimping or welding to ensure connection strength and sealing. The connection method between the brass joint 3 and other components can be selected according to specific needs, such as threaded connection, flange connection, etc. Preferably, the brass joint 3 is in the shape of a T-shaped column, which is suitable for connection with other components and is simple to connect.

[0031] In order to reasonably arrange the route of the ventilation aluminum tube 2, effectively utilize the space, and avoid the structure volume being too large, two installation columns 5 are arranged at intervals at the lower end of the valve body 1; there is an interval space 6 between the two installation columns 5; the ventilation aluminum tube 2 is first extended downwardly parallel to the installation columns 5, and then bent and horizontally passed through the interval space 6. Taking advantage of the ventilation aluminum tube 2's characteristics of bending, twisting, and bypassing obstacles, the convenient and bendable ventilation aluminum tube 2 can easily adapt to various complex installation environments, and the ventilation aluminum tube 2 can be easily bent and passed through the interval space 6, which is conducive to reducing the difficulty and cost of installation, and effectively utilizing the space to avoid the structure volume being too large.

[0032] The combined structure of the valve and the pipe also includes a valve core, a rotating shaft 7 and an air outlet 8; the valve core is installed in the inner cavity of the valve body 1; the rotating shaft 7 is rotatably connected to the valve body 1 and connected to the valve core; the two air outlets 8 are both connected to the inner cavity of the valve body 1. By providing two air outlets 8, when the rotating shaft 7 is used to rotate the valve core to control the opening of the air inlet, air can be discharged in both directions, which is convenient for the gas equipment to use multiple gas outlets and improves the flexibility of use.

[0033] In summary, the embodiment of the utility model provides a combined structure of a valve and a pipe, wherein the combined structure of the valve and the pipe has the following advantages:

[0034] 1. Using ventilation aluminum tube 2 instead of copper tube simplifies the production process, is easy to process, reduces manual operation, improves production efficiency, and the price of aluminum is relatively low, which can effectively reduce production costs in terms of simplifying production processes and materials, and help improve the market competitiveness of gas equipment.

[0035] Second, the use of ventilation aluminum tubes 2 instead of copper tubes has less impact on the environment during production and use, which helps to achieve green production and sustainable development, thereby improving environmental protection performance.

[0036] 3. By combining the valve body 1 with the ventilation aluminum tube 2, the ventilation aluminum tube 2 is used instead of the traditional copper tube to achieve lightweight structure. The density of aluminum is much lower than that of copper. Therefore, the aluminum tube of the same volume is lighter than the copper tube, which is beneficial to reduce the weight of the entire fluid control system and facilitates installation and transportation.

[0037] Fourth, the outer diameter and wall thickness of the ventilation aluminum tube 2 are controlled within a set range. Such a size design ensures that the ventilation aluminum tube 2 has sufficient strength to withstand the pressure of the internal gas, while remaining light and flexible, convenient for installation and connection, and reduces material costs. Moreover, such a ventilation aluminum tube 2 is combined with a brass joint 3. The design of the brass joint 3 enables the aluminum tube to be reliably connected to other pipes or equipment, while improving the sealing performance of the connection.

[0038] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
