The utility model relates to the field of refrigeration accessories, in particular to a silencer. The existing silencers are made of traditional pure copper. In recent years, a new type of spinning silencer, the former is still stagnant because of the high cost of pure copper. Although the price of the latter is lower than the cost of pure copper silencer, it has been unable to solve the problem of welding leakage. The utility model is a kind of muffler, which is provided with a plurality of inward convex ports on the cylinder body, the main body is against the card mouth, the main body is composed of two parts of the large end and the conical end, and the large end on the body is fitted to the barrel and is welded through welding, and the silencing place is carried out because of the change of the end of the large end and the cone end. Reason. The utility model is used as a spinning structure, without welding, to achieve a complete sealing connection and avoid welding leakage. By changing the cross section area of the pipeline flowing through the refrigerant, the noise produced by the high-speed flow of the refrigerant in the pipeline is significantly reduced and the cost is reduced.
【技术实现步骤摘要】
一种消音器
本技术涉及制冷配件领域,具体涉及一种消音器。
技术介绍
消音器是空调制冷系统重要部件,一般安装于空调制冷管路中,或空气动力设备的气流通道或进、排气系统中,通过突然改变空调系统内冷媒流经的管路横截面积来降低或消除冷媒在管路中高速流动产生的噪音。现有的消音器有传统的纯铜制造,近年来新兴的一种旋压式消音器,前者因纯铜制造成本高昂一直处于停滞状态,后者虽然价格要比纯铜消音器成本低,但一直无法解决产品因焊接泄漏问题。
技术实现思路
本专利技术的目的就是针对现有技术之不足,提供一种能防止泄漏和结构简单的消音器。一种消音器,包括筒体,所述的筒体的两端缩口,在筒体上设有多个内凸的卡口,主体抵靠在卡口上,主体由大端和锥形端两部分组成,主体上的大端贴合在筒体内,并通过焊接固接,因大端和锥形端截面积的改变,进行消音处理。作为对上述方案的进一步完善和补充,本实用还包括以下附加技术特征:所述的卡口有两排,定位好。所述的筒体的材料为不锈钢,成本相对较低。所述的主体的材料为不锈钢,可以进行冲压,尺寸精确。使用本技术可以达到以下有益效果:因筒体为旋压结构,无须焊接,实现了完全密封连接,避免出现焊接泄漏,通过改变冷媒流经的管路的横截面积,显著降低了冷媒在管路中高速流动产生的噪音,相对于传统结构,也降低了成本。附图说明图1是本技术的结构示意图。具体实施方式下面结合附图对本技术的具体实施方式进行详细描述。如图1所示,本技术为一种消音器。本实施例所述的消音器,包括圆柱形的筒体1,所述的筒体1的两端缩口处理,在筒体1上设有有两排多个内凸的圆环形的卡口11,中空的主体2抵靠在两卡口11上,定位精 ...
