连接管组件及具有其的控制阀组件
本申请要求于2021年9月22日提交至中国国家知识产权局、申请号为202122297347.5、发明名称为“连接管组件及具有其的控制阀组件”的专利申请的优先权。
技术领域
本申请涉及控制阀技术领域，具体而言，涉及一种连接管组件及具有其的控制阀组件。
背景技术
目前，现有的控制阀包括阀体和连接管，阀体上设置有阀管，连接管通过阀管与阀体连通，在现有技术中，阀管与连接管通过焊接固定，在焊接过程中由于焊料添加过多或者进行多次插拔焊接，会在焊接区域形成焊瘤和焊渣，焊瘤和焊渣容易从阀管掉进阀体内，从而造成阀体内的通路堵塞，影响了控制阀的正常使用。
发明内容
本申请提供一种连接管组件及具有其的控制阀组件，以解决现有技术中的连接管组件焊接不良而影响控制阀正常使用的问题。
根据本申请的一个方面，提供了一种连接管组件，连接管组件包括：第一连接管，具有相对设置的第一端和第二端；连接套管，第一连接管的第一端位于连接套管内，连接套管具有相对设置的第一端和第二端，连接套管的第一端与第一连接管的外侧壁连接，连接套管的中部的内壁与第一连接管的第一端的外壁之间具有间隙，间隙形成容纳腔；第二连接管，第二连接管的一端与连接套管的第二端连接，且第二连接管的端部位于连接套管内。
通过设置上述结构，将第一连接管的第一端设置在连接套管内，并且连接套管的中部的内壁与第一连接管的第一端的外壁之间具有间隙，间隙形成容纳腔，该容纳腔可以容纳连接套管与第二连接管焊接时产生的焊瘤、焊渣或者多余的焊料，能够避免焊瘤、焊渣或者多余的焊料从焊接处流出，保证了控制阀的正常使用。
进一步地，连接套管20的壁厚为T，所述间隙在径向上的最大尺寸为t，0＜t＜T。将连接套管的壁厚设置为T，间隙在径向上的最大尺寸设置为t，0＜t＜T，在提高焊接效果的同时能够进一步保证控制阀的正常使用。
进一步地，第二连接管的位于连接套管内的端部与第一连接管的第一端相抵接，第二连接管的位于连接套管内的端部与第一连接管的第一端的外壁以及连接套管的中部的内壁相互配合以封闭容纳腔。如此设置，通过第一连接管、连接套管和第二连接管相互连接将容纳腔 封闭，能够防止焊接后的焊瘤、焊渣或者多余的焊料从容纳腔溢出，从而避免了焊瘤、焊渣或者多余的焊料流入控制阀，保证了控制阀运行时的稳定性。
进一步地，连接套管包括相互连接的第一段、第二段和第三段，连接套管的第一段与第一连接管连接，连接套管的第三段与第二连接管连接，第二段的内壁与第一连接管的第一端的外壁之间形成容纳腔，第二段的内径由第一段至第三段的方向逐渐增大。上述设置，将连接套管设置为变径结构，既能够保证连接套管与第一连接管和第二连接管的连接，提高了焊接时的稳定性，也有利于形成容纳腔以容纳焊接后的焊瘤、焊渣或者多余的焊料。
进一步地，第三段的内径为D，第一连接管的第一端的外壁的直径为d，t＝(D-d)*0.5。如此设置，结构简单，便于对容纳腔的加工。
进一步地，第一段的长度为L1，连接套管的第一端的端面与第一连接管的第一端的端面之间的距离为L2，容纳腔沿轴向的最大长度为L，L＝L2-L1且L>0。上述设置，既能够保证容纳腔的容量，同时将容纳腔沿轴向的最大长度L设置为L＝L2-L1且L>0也有利于连接套管与第一连接管的定位，从而有利于组件连接后的焊接。
进一步地，连接套管的内壁上设置有限位结构，限位结构与第一连接管的第一端在轴向上具有间隔，限位结构用于限制第二连接管在连接套管内的轴向位置。通过限位结构，能够使第二连接管与第一连接管的端面之间具有一定距离，如此进一步增大了容纳腔的容纳面积，从而能够容纳更多的焊瘤、焊渣或者多余的焊料，进一步提高了焊接效果。
进一步地，连接套管的内壁上有多个凸起，多个凸起形成限位结构，多个凸起环形间隔设置在连接套管的内壁上。通过上述设置，能够进一步地限制第二连接管在连接套管内的轴向位置，从而保证了第二连接管与连接套管连接的稳定性。
进一步地，限位结构包括凸起，凸起环形设置在连接套管的内壁上。如此设置，能够增加凸起与第二连接管的接触面积，能够限制第二连接管在连接套管内的轴向位置，便于第二连接管与连接套管的焊接，从而进一步保证了第二连接管与连接套管连接的稳定性。
根据本申请的另一方面，提供了一种控制阀组件，控制阀组件包括上述的连接管组件。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何限制。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如图1至图3所示，本申请实施例一提供了一种连接管组件，该连接管组件包括：第一连接管10、连接套管20和第二连接管40。其中，第一连接管10，具有相对设置的第一端和第二端，连接套管20，第一连接管10的第一端位于连接套管20内，连接套管20具有相对设置的第一端和第二端，连接套管20的第一端与第一连接管10的外侧壁连接，连接套管20的中部的内壁与第一连接管10的第一端的外壁之间具有间隙，间隙形成容纳腔30，第二连接管40，第二连接管40的一端与连接套管20的第二端连接，且第二连接管40的端部位于连接套管20内。在本实施例中，第一连接管与阀口连接，第二连接管与外界的其他设备连接。
通过设置上述结构，将第一连接管10的第一端设置在连接套管20内，并且连接套管20的中部的内壁与第一连接管10的第一端的外壁之间具有间隙，间隙形成容纳腔30，该容纳腔30可以容纳连接套管20与第二连接管40焊接时产生的焊瘤、焊渣或者多余的焊料，能够避免焊瘤、焊渣或者多余的焊料从焊接处流出，保证了控制阀的正常使用。
进一步地，连接套管20的壁厚为T，所述间隙在径向上的最大尺寸为t，0＜t＜T。将连接套管的壁厚设置为T，间隙在径向上的最大尺寸设置为t，0＜t＜T，在提高焊接效果的同时能够进一步保证控制阀的正常使用。
其中，当t>T时，在安装过程中容易使第二连接管40的端部伸入连接套管20的中部的内壁与第一连接管10的第一端的外壁之间的间隙内，如此会导致第一连接管10和连接套管20之间无法形成容纳腔30，从而不能够容纳焊瘤、焊渣或者多余的焊料。因此，在本申请中，将t设置在0至T之间，能够在第一连接管10和连接套管20之间形成容纳腔30，在焊接时，焊料会沿着第二连接管40和连接套管20之间的间隙流动，最终产生的焊瘤、焊渣或者多余 的焊料会容纳在容纳腔30内，从而保证了连接管组件的焊接效果。具体地，t可以设置为0.3T、0.5T或0.8T。
其中，第二连接管40的位于连接套管20内的端部与第一连接管10的第一端相抵接，第二连接管的位于连接套管20内的端部与第一连接管10的第一端的外壁以及连接套管20的中部的内壁相互配合以封闭容纳腔30。如此设置，通过第一连接管10、连接套管20和第二连接管相互连接将容纳腔30封闭，能够防止焊接后的焊瘤、焊渣或者多余的焊料从容纳腔30内溢出，从而避免了焊瘤、焊渣或者多余的焊料流入控制阀，保证了控制阀运行时的稳定性。
进一步地，连接套管20包括相互连接的第一段21、第二段22和第三段23，连接套管20的第一段21与第一连接管10连接，连接套管20的第三段23与第二连接管连接，第二段22的内壁与第一连接管10的第一端的外壁之间形成容纳腔30，第二段22的内径由第一段21至第三段23的方向逐渐增大。上述设置，将连接套管20设置为变径结构，既能够保证连接套管20与第一连接管10和第二连接管40的连接，提高了焊接时的稳定性，也有利于形成容纳腔30以容纳焊接后的焊瘤、焊渣或者多余的焊料。
如图2所示，第三段23的内径为D，第一连接管10的第一端的外壁的直径为d，t＝(D-d)*0.5。如此设置，其结构简单，便于对容纳腔30的加工。
具体地，第三段23的长度大于第一段21的长度。如此设置，能够增大第三段23与第二连接管的连接面积，从而有利于连接套管20与第二连接管的焊接，提高了二者焊接后的结构强度。
进一步地，第一段21的长度为L1，连接套管20的第一端的端面与第一连接管10的第一端的端面之间的距离为L2，容纳腔30沿轴向的最大长度为L，L＝L2-L1且L>0。上述设置，既能够保证容纳腔30的容量，同时将容纳腔30沿轴向的最大长度L设置为L＝L2-L1且L>0也有利于连接套管20与第一连接管10的定位，从而有利于组件连接后的焊接。
图4和图5所示，本申请实施例二提供了一种连接管组件，与实施例一的区别在于：连接套管20的内壁上设置有限位结构24，限位结构24与第一连接管10的第一端在轴向上具有间隔，限位结构24用于限制第二连接管在连接套管20内的轴向位置。通过限位结构24，能够使第二连接管与第一连接管10的端面之间具有一定距离，如此进一步增大了容纳腔30的容纳面积，从而能够容纳更多的焊瘤、焊渣或者多余的焊料，进一步提高了焊接效果。
进一步地，连接套管20的内壁上有多个限位结构24，多个限位结构24环形设置在连接套管20的内壁上。通过上述设置，能够进一步地限制第二连接管在连接套管20内的轴向位置，从而保证了第二连接管与连接套管20连接的稳定性。
进一步地，限位结构24包括凸起，凸起环形设置在连接套管20的内壁上。如此设置，能够增加凸起与第二连接管40的接触面积，能够限制第二连接管40在连接套管20内的轴向位置，便于第二连接管40与连接套管20的焊接，从而进一步保证了第二连接管40与连接套管20连接的稳定性。
本申请另一实施例提供了一种控制阀组件，该控制阀组件包括上述实施例提供的连接管组件。
通过本申请提供的技术方案，将第一连接管10的第一端设置在连接套管20内，并且连接套管20的中部的内壁与第一连接管10的第一端的外壁之间具有间隙，间隙形成容纳腔30，该容纳腔30可以容纳连接套管20与第二连接管40焊接时产生的焊瘤、焊渣或者多余的焊料，能够避免焊瘤、焊渣或者多余的焊料从焊接处流出，在提高焊接效果的同时能够保证控制阀的正常使用。同时，在连接套管20的内壁上设置有限位结构24，如此保证了第二连接管40与连接套管20连接的稳定性。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本申请的范围。同时，应当明白，为了便于描述，附图中所示出的各个部分的尺寸并不是按照实际的比例关系绘制的。对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为授权说明书的一部分。在这里示出和讨论的所有示例中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它示例可以具有不同的值。应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
在本申请的描述中，需要理解的是，方位词如“前、后、上、下、左、右”、“横向、竖向、垂直、水平”和“顶、底”等所指示的方位或位置关系通常是基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，在未作相反说明的情况下，这些方位词并不指示和暗示所指的装置或元件必须具有特定的方位或者以特定的方位构造和操作，因此不能理解为对本申请保护范围的限制；方位词“内、外”是指相对于各部件本身的轮廓的内外。
为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。
此外，需要说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本申请保护范围的限制。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
