Title
(EN) Copper pipe online automatic purging device
(ZH) 一种铜管在线自动吹扫装置
Abstract
(EN) The utility model discloses a copper pipe online automatic purging device which comprises a shell, a cylindrical sealing cavity for inserting a copper pipe is formed in the shell, one end of the cylindrical sealing cavity is located on the side portion of the shell and forms a copper pipe inserting opening, the other end of the cylindrical sealing cavity is closed, and the other end of the cylindrical sealing cavity is closed. An annular sealing cavity communicated with the cylindrical sealing cavity is formed in the portion, located on the side portion of the cylindrical sealing cavity, in the shell, and a piston used for compressing a sealing piece to tightly hold the copper pipe is arranged on the annular sealing cavity in a sliding mode. A first compressed air port and a second compressed air port which are used for feeding or discharging compressed air and a nitrogen inlet which is formed in the shell and used for feeding nitrogen are respectively formed in the shell. Compared with the prior art, the nitrogen purging device has the beneficial effects that 1, the nitrogen purging device can bear nitrogen purging with higher pressure; the sealing ring is durable and low in cost, and the number of times of sealing replacement by workers is reduced.
(ZH) 本实用新型公开了一种铜管在线自动吹扫装置,包括一壳体,壳体内构成有一供铜管插入的圆柱状密封腔体,圆柱状密封腔体的一端位于壳体的侧部并形成为一铜管插入口,所述圆柱状密封腔体的另一端封闭,在所述壳体内位于所述圆柱状密封腔体的侧部形成有一与所述圆柱状密封腔体连通的环形密封腔体,所述环形密封腔体上滑动配置有用以压缩密封件抱紧所述铜管的活塞,所述壳体上分别设置有用以供压缩空气进气或排气的第一压缩空气口和第二压缩空气口以及设置在所述壳体上用以供氮气进入的氮气入口。本实用新型的有益效果在于:本实用新型与现有技术相比,1、能够承受较大压力的氮气吹扫。2、密封圈比较经久耐用,成本低,减轻了工人更换密封的次数。
