Description

一种分气管组件及燃气灶Air distribution pipe assembly and gas stove 技术领域Technical field

本申请涉及燃气管连接接头技术领域,具体涉及一种分气管组件及燃气灶。本申请要求于2019年2月22日提交至中国国家知识产权局、申请号为201910136654.X、发明名称为“一种分气管组件及燃气灶”的专利申请的优先权。 The application relates to the technical field of gas pipe connection joints, and in particular to a gas distribution pipe assembly and a gas stove. This application claims the priority of the patent application filed to the State Intellectual Property Office of China on February 22, 2019, with the application number of 201910136654.X and the invention title of "a sub-pipe assembly and gas stove".

背景技术Background technique

燃气灶结构中,分气管连接着阀体和喷嘴,由于分气管在灶具工作时极限温度可能达到150℃以上,为确保分气管使用寿命及可靠性,目前市场上几乎都采用金属气管以及相应的金属连接接头,而且在密封面上不能使用垫片、胶水之类辅助密封材料。通常阀体接头为铜;分气管为铝;分气管两端接头为铜;喷嘴为铜。In the gas stove structure, the gas pipe is connected to the valve body and the nozzle. Because the limit temperature of the gas pipe may reach 150℃ or more when the stove is working, in order to ensure the service life and reliability of the gas pipe, almost all metal gas pipes and corresponding Metal connection joints, and auxiliary sealing materials such as gaskets and glue cannot be used on the sealing surface. Usually the valve body joint is copper; the gas manifold is aluminum; the joints at both ends of the gas manifold are copper; the nozzle is copper.

分气管较薄,一般分气管壁厚为0.6mm,由于在整机装配过程中要手工调整分气管角度,壁厚太厚会导致分气管强度过高而不方便手工调节。但是,如图1分气管的结构所示,分气管与喷嘴及阀体连接方式,分气管两端被加工成“喇叭口”形状,“喇叭口”与喷嘴及阀体对接,再用螺母压紧。“喇叭口”由气管两端直接涨管加工而成,该处材料厚度减少到0.4mm左右,在螺母压紧时“喇叭口”处常常因壁厚较薄而被拧破,从而产生燃气泄露。The trachea is relatively thin. Generally, the wall thickness of the trachea is 0.6mm. Because the angle of the trachea must be manually adjusted during the assembly process of the whole machine, too thick wall thickness will cause the trachea to be too strong and not convenient for manual adjustment. However, as shown in the structure of the air pipe in Figure 1, the air pipe is connected to the nozzle and valve body. Both ends of the air pipe are processed into a "bell mouth" shape. The "bell mouth" is butted with the nozzle and valve body, and then the nut is pressed tight. The "bell mouth" is processed by directly expanding the two ends of the air pipe. The thickness of the material at this place is reduced to about 0.4mm. When the nut is compressed, the "bell mouth" is often broken due to the thin wall thickness, resulting in gas leakage .

在分气管连接阀体和喷嘴时,为了尽可能节约空间,分气管一般都有数次弯曲,而且不是平面上的弯曲,而是空间上的弯曲,这就常常出现分气管与阀体及喷嘴连接处同轴度偏差较大的情况,(也就是“装歪了”)。分气管的“喇叭口”与喷嘴配合面出现歪斜,这样也会导致分气管与阀体及喷嘴连接处泄露。In order to save space as much as possible when the air manifold is connected to the valve body and the nozzle, the air manifold generally has several bends, and it is not a flat curve, but a spatial curve. This often occurs when the air manifold is connected to the valve body and the nozzle. In the case of large deviations in coaxiality, (that is, "installed crooked"). The "flare" of the air distribution pipe and the nozzle mating surface are skewed, which will also cause leakage at the connection between the air distribution pipe and the valve body and nozzle.

实施例1 Example 1

本实施例提供一种分气管组件,适于与端部外侧成型有螺纹的连接件连接。在本实施例中,如图1-4所示,所述连接件为喷嘴1或阀体。该分气管组件包括:分气管2、套设在分气管2上的螺母5和承力件,其中分气管2的两端的结构相同,均成型有喇叭口3,螺母5适于与所述连接件螺纹连接,所述承力件处于所述螺母5与所述喇叭口3之间,所述螺母5与所述连接件螺纹连接后,所述承力件处于所述喇叭口3外壁与所述螺母5内壁之间。This embodiment provides a gas distribution pipe assembly, which is suitable for connecting with a connecting piece formed with threads on the outside of the end. In this embodiment, as shown in Figures 1-4, the connecting piece is the nozzle 1 or the valve body. The gas distribution pipe assembly includes: a gas distribution pipe 2, a nut 5 sleeved on the gas distribution pipe 2 and a bearing member, wherein the two ends of the gas distribution pipe 2 have the same structure, and both are formed with a bell mouth 3, and the nut 5 is suitable for connecting with the The bearing member is threadedly connected, the bearing member is located between the nut 5 and the bell mouth 3. After the nut 5 is threadedly connected to the connecting member, the bearing member is located between the outer wall of the bell mouth 3 and the Between the inner wall of the nut 5.

在本实施例中,所述承力件为环绕所述喇叭口3的垫片4,为保证喇叭口3的外壁不会与螺母5的内壁直接接触,保护喇叭口3不会被破坏,所述垫片4与所述喇叭口3的形状相匹配。如图2所示,所述螺母5包括与所述螺纹的外径相适配的第一段51、与所述分气管2的外径相适配的第二段52、以及连接所 述第一段51与所述第二段52的圆锥形过渡段53,所述螺母5将所述分气管2与所述连接件连接时,所述垫片4的至少一个外端抵靠在所述螺母5的内表面上,这样设置使得分气管2与喷嘴1或阀体的连接可靠稳定。In this embodiment, the bearing member is a gasket 4 surrounding the bell mouth 3. To ensure that the outer wall of the bell mouth 3 will not directly contact the inner wall of the nut 5, and protect the bell mouth 3 from being damaged, The gasket 4 matches the shape of the bell mouth 3. As shown in Figure 2, the nut 5 includes a first section 51 that is adapted to the outer diameter of the thread, a second section 52 that is adapted to the outer diameter of the gas manifold 2, and is connected to the second section. A section 51 and a conical transition section 53 of the second section 52. When the nut 5 connects the gas distribution pipe 2 to the connecting piece, at least one outer end of the gasket 4 abuts against the On the inner surface of the nut 5, this arrangement makes the connection between the gas distribution pipe 2 and the nozzle 1 or the valve body reliable and stable.

分气管2在进行安装时,由于燃气灶内部空间较小及节约成本的考虑,需要将分气管2弯折成曲折的三维空间管道,还需要用手掰分气管2,调整两端的喇叭口3分别对准阀体和喷嘴1,如果分气管2壁厚过厚,手掰不动,安装难度大幅增加,为避免这种情况,方便对分气管2进行调整安装,在本实施例中,所述分气管2采用合金材料气管,所述分气管2的两端的壁厚大于中间管段的壁厚。During the installation of the gas distribution pipe 2, due to the small internal space of the gas stove and cost-saving considerations, the gas distribution pipe 2 needs to be bent into a tortuous three-dimensional space pipe, and the gas distribution pipe 2 needs to be broken by hand to adjust the bell mouth 3 at both ends. Align the valve body and nozzle 1, respectively. If the wall thickness of the gas manifold 2 is too thick and the hand does not move, the installation difficulty will be greatly increased. To avoid this situation, it is convenient to adjust and install the gas manifold 2. In this embodiment, The gas distribution pipe 2 adopts an alloy material gas pipe, and the wall thickness of the two ends of the gas distribution pipe 2 is greater than the wall thickness of the middle pipe section.

实际进行连接安装时,调整分气管2的两端使两端的喇叭口3分别对准阀体和喷嘴1,然后分别紧固两端的螺母5,螺母5在紧固的过程中,由于承力件位于喇叭口3外壁与螺母5的内壁之间,承力件代替喇叭口3承受螺母5的压紧力、破坏性扭力,承力件将压紧力均匀传递给喇叭口3,从而保护喇叭口3不被压紧力及破坏性扭力直接将其撕裂造成气体泄漏,从而保证了分气管组件的密封效果。在采用本实施例提供的分气管组件后,在工艺等条件未变更的情况下,可将分气管2与阀体及喷嘴1连接处泄漏率由原来的1.5%左右降低至0.3%以下。When actually connecting and installing, adjust the two ends of the air distribution pipe 2 so that the bell mouths 3 at both ends are aligned with the valve body and the nozzle 1, and then tighten the nuts 5 at both ends. The nuts 5 are tightened due to the bearing parts. Located between the outer wall of the bell mouth 3 and the inner wall of the nut 5, the bearing member replaces the bell mouth 3 to bear the pressing force and destructive torque of the nut 5, and the bearing member transmits the pressing force to the bell mouth 3 evenly, thereby protecting the bell mouth 3 It will not be directly torn by compression force and destructive torsion force to cause gas leakage, thereby ensuring the sealing effect of the gas manifold assembly. After using the gas distribution pipe assembly provided by this embodiment, the leakage rate of the connection between the gas distribution pipe 2 and the valve body and the nozzle 1 can be reduced from about 1.5% to less than 0.3% under the condition that the process and other conditions are not changed.

在可替换的实施例中,所述垫片4可替换为其他结构的承力件,比如间隔环绕在喇叭口3外侧的多个凸块。 In an alternative embodiment, the spacer 4 can be replaced with a bearing member of other structure, such as a plurality of bumps surrounding the bell mouth 3 at intervals.

在可替换的实施例中,所述阀体或喷嘴1可替换为用于其他需要密封连接的连接件。 In an alternative embodiment, the valve body or nozzle 1 can be replaced with other connectors that require a sealed connection.
