Abstract

本实用新型所设计的一种变径进出口接头，涉及接头，解决了目前的接头与圆管对接不紧密的技术问题。本实用新型包括一中空管件，其特征是所述的中空管件一端内开一圆孔，另一端内开一椭圆孔，所述的圆孔与椭圆孔连通。本实用新型所涉及的一种变径进出口接头，可与圆管和椭圆形的对接口连接紧密，避免对接后在输送介质时引起的渗漏，并且采用变径后，对管件一端采用模压成椭圆形，使产品高度下降，而侧模方向变宽，节省了焊料，提高了产品的可靠性。

Description

一种变径进出口接头
技术领域
本实用新型涉及接头，尤其是一种变径进出口接头。
背景技术
目前在吹胀式产品应用于太阳能过程中，圆管与吹胀板的连接头两端均为圆孔，使得圆管与板胀开的椭圆形对接口很难等距密切连接，该部位往往是导致该产品漏介质的主要部位。
发明内容
本实用新型的目的是为了解决上述现有技术的不足而提供一种变径进出口接头，与圆管和椭圆形的吹胀板接口形状均相配，连接紧密，避免输送介质时的渗漏。
为了达到上述目的，本实用新型所设计的一种变径进出口接头，包括一中空管件，其特征是所述的中空管件一端内开一圆孔，另一端内开一椭圆孔，所述的圆孔与椭圆孔连通，圆孔连接圆管，椭圆孔与吹胀形成的椭圆形对接口相连接，形状尺寸均相配，连接紧密，避免对接后在输送介质时引起的渗漏，采用变径后，对管件一端采用模压成椭圆形，使产品高度下降，而侧模方向变宽，节省了焊料，提高了产品的可靠性。
作为上述结构的进一步完善和补充，本实用新型还包含以下附加技术特征或这些特征的任意组合：
所述的圆孔向内逐渐变径与椭圆孔相匹配，介质在接头内流通更为顺畅。
所述的管件外壁设有焊盘，方便连接。
本实用新型所涉及的一种变径进出口接头，可与圆管和椭圆形的对接口连接紧密，避免对接后在输送介质时引起的渗漏，并且采用变径后，对管件一端采用模压成椭圆形，使产品高度下降，而侧模方向变宽，节省了焊料，提高了产品的可靠性。
附图说明
图1是本实用新型的结构剖视示意图；
图2是图1的左视图；
图3是图1的右视图。
图中：1-管件、2-圆孔、3-椭圆孔。
具体实施方式
下面通过实施例结合附图对本实用新型作进一步的描述。
如图1-图3所示，本实施例描述的一种变径进出口接头，包括一中空管件1，所述的中空管件1一端内开一圆孔2，另一端内开一椭圆孔3，所述的圆孔2与椭圆孔3连通，所述的圆孔2向内逐渐变径与椭圆孔3相匹配，所述的管件1外壁设有焊盘。
