The utility model is suitable for the manufacturing field of parts and components of refrigeration system. The utility model provides a stainless steel silencer, which comprises a stainless steel silencer, a stainless steel end cover is welded at the upper and lower ports of the stainless steel silencer, a cylindrical through hole is opened in the middle axle of the stainless steel end cover and a connecting pipe matching the through hole in diameter is installed, and a circle of steps is formed at the end of the connecting pipe, and stainless steel The first welding ring is fixed between the inner wall of the end cap and the outer wall of the connecting pipe is evenly distributed with several vertical fine grooves. After the first welding ring is completed, the solder melts and flows to the space between the fine groove and the inner wall of the through hole of the stainless steel end cap, and solidifies. It can be assembled in a tight fit manner. The gap is controlled by the groove depth of the fine groove, and the solder passes through capillary phenomenon. Completely filling each gap avoids the gap between the smooth external connecting pipe and the stainless steel end cap, which leads to the gas hole and welding breakage.

一种不锈钢消音器
本技术属于制冷系统零部件制造领域,尤其涉及一种不锈钢消音器。
技术介绍
消音器是一种制冷系统中使用的既可使气流通过又能有效降低噪音的设备,专利号为201620806199.1的技术专利公开了一种不锈钢消音器,其包括一段直径较大的消音筒,消音筒两端有端盖,两个端盖上分别穿入并焊接的直径较小的进气管和出气管。目前,市面上的消音器上所采用的连接管(进气管和出气管)外部光滑,连接管外部和端盖之间必然会存在少许间隙,焊接过程中个别产品会出现气孔和断焊现象,焊料腐蚀后会从中间气孔和断焊处产生泄漏。
技术实现思路
鉴于上述问题,本技术的目的在于提供一种不锈钢消音器,旨在解决现有不锈钢消音器焊接不牢固、容易存在间隙的技术问题。本技术采用如下技术方案:一种不锈钢消音器,包括不锈钢消音筒,所述不锈钢消音筒的上下两个端口各焊接一个不锈钢端盖,所述不锈钢端盖的中轴开有圆柱形通孔,所述不锈钢端盖的通孔内安装有直径与所述通孔匹配的连接管,所述连接管的尾端形成一圈台阶,所述台阶与不锈钢端盖内壁之间焊接第一焊环固定,所述连接管的外壁上均匀分布有若干个竖直的细凹槽,第一焊环焊接完成后,焊料熔融并流至所述细凹槽与不锈钢端盖的通孔内壁之间空间并凝固。进一步的,所述不锈钢消音筒两端与不锈钢端盖内壁之间设置有第二焊环,通过所述第二焊环,所述不锈钢消音筒与不锈钢端盖焊接为一体。进一步的,所述连接管为紫铜连接管,所述第一焊环和第二焊环为青铜焊环。进一步的,所述紫铜连接管的细凹槽的槽深为0.5毫米,拉丝数为36条。本技术的有益效果是:本技术的不锈钢消音器结构设计简单巧妙,连接管的尾端形成一圈台 ...
