Description

一种可任意调整出口朝向的水泵 技术领域
本发明涉及水泵技术领域，尤其是一种可任意调整出口朝向的水泵。
背景技术
智能泵是具有一定的计算机处理能力,可以部分替代人工智力的泵或泵系统的总称。随着科学技术的发展,特别是计算机和信息技术的迅速发展,传统的泵制造业已向着节能化、智能化、现代化的方向发展。智能泵的设计要求不断的朝向更安全、更稳定、更美观、更环保节能的方向发展。目前市面上存在的大多数智能泵，其出口朝向是水平的，例如，中国专利号CN201720236612.X于2017年10月20日授权公告的一种带排气功能的智能泵站，包括底座和筒体，筒体两侧分别设置出水口和进水口，出水口呈水平设置。智能泵中的出水管需要连接的管路相比传统泵要多，通常采用四通接头，四通接头直接与泵体出口螺纹连接，存在出口朝向不易把控，影响美观的问题，除非采用螺纹胶固定朝向，但这不利于后期维护，因此，采用接头直接与泵体螺纹连接并不能满足客户对水泵出口朝向的要求。针对新市场需求，开发一种可任意调整出口朝向的水泵是迫切需求的。
发明内容
基于现有技术中的上述不足，本申请公开了一种可任意调整出口朝向的水泵，解决现有技术中接头与泵体螺纹连接造成的出水口朝向难以调节的问题，并且方便后期维护。
本发明的另一个目的是，用于智能泵中，智能泵需要涉及到排气功能，本发明所公开的出水结构具有更高的气液分离效率，能够提高排气的可靠性。
为实现上述目的，本发明提出以下技术方案。
一种可任意调整出口朝向的水泵，包括活接接管和出口管，活接接管与水泵连接，活接接管上设有锁紧凸台，锁紧凸台上设有与出口管连接的连接件，活接接管和出口管之间设有密封件。
通过锁紧凸台配合连接件能够锁紧活接接管和出口管，活接接管与水泵连接，出口管可以相对活接接管转动任意角度后再通过连接件锁紧连接，从而实现多通路的出口管相对水泵朝向的任意调节，使得智能泵整体成型后的更加美观，结构位置更加合理，同时也方便后期的维护调整。
作为优选，活接接管包括伸入到出口管内的进口管，进口管和锁紧凸台之间形成密封台，密封件设置在密封台上，出口管上设有对应密封台的压紧斜面。压紧斜面配合密封台完成密封件的压紧，提供可靠的密封作用，在活接接管转动任意角度后，密封件仍然能够提供 可靠的密封作用。
作为优选，出口管是内部管路呈“十”字形的四通管，出口管上设有接合段，接合段和出口管之间设有内径小于活接接管最小内径的挡水环。出口管的四个接头能够分别配合不同的管道，完成智能泵的管道连通，接合段用于与锁紧螺母连接，挡水环用于重整流体，在水泵的水体经过活接接管流入到出口管时，水体经过多次的增速和碰撞，方便四通管内的水路分配，传统泵出口管和水泵直连后，水泵出水大部分沿轴线运动，水体集中，不利于四通管其他接口的排气或水流改道，而本申请进行的挡水环改进能够方便水体的改道，并能有效提高水体内气液分离的效率，在智能泵需要对水体排气时，提高排气效率。
作为优选，连接件采用锁紧螺母，锁紧螺母和出口管通过螺纹连接，锁紧螺母的一端设有用于压紧锁紧凸台的压紧环，压紧环的内径小于锁紧凸台的外径。锁紧螺母和出口管螺纹连接时，压紧环压紧锁紧凸台，实现出口管和活接接管之间的压紧配合，该压紧配合并不受出口管转动角度的限制，因此可以完成出口管任意转动角度后的锁紧，实现出口管朝向的调节。
作为优选，进口管的端部设有第一过渡倒角，锁紧凸台朝向进口管一端的外侧设有第二过渡倒角，锁紧凸台对应进口管的端面的外径小于出口管朝向锁紧凸台一端的端面内径。第一过渡倒角和第二过渡倒角的设置在活接接管朝向出口管的一端形成类似圆台面的配合结构，因为锁紧凸台对应进口管的端面的外径比出口管朝向锁紧凸台一端的端面内径小，因此在进口管插入到出口管内配合时，锁紧凸台和出口管之间留有余量，从而在活接接管和出口管连接时，出口管的端面能够压紧密封件，保持对密封件压紧密封作用的可靠性，避免出口管和活接接管之间出现位置干扰。
作为优选，活接接管朝向水泵的一端设有与水泵连接的外螺纹段，水泵上设有与外螺纹段连接的内螺纹段，内螺纹段的外端与外螺纹段之间设有弹性密封圈。活接接管通过外螺纹段完成与水泵上内螺纹段的螺纹锁紧，配合弹性密封圈保持密封，连接方便，结构可靠。
作为优选，外螺纹段的内部孔径小于活接接管的内部孔径，外螺纹段和活接接管之间设有过渡弧面。水体从水泵射出时，从内螺纹段流入到活接接管位置时会出现一个横截面扩张的情况，水流的水压会在瞬间减小，使得气液有效分离，水体大部分在管道下方碰撞涌入到四通管内，气体居于上层，可靠溢出，在智能泵排气环节能够有效提高排气效率。
作为优选，接合段上设有连接挡水环的连接环，挡水环的两端分别伸出到连接环的外部，挡水环的形状为圆环形，挡水环朝向活接接管的一端的外侧面上设有第一过渡圆角，挡水环背对活接接管的一端的内侧面上设有第二过渡圆角。挡水环的直径还小于外螺纹段的内 径，挡水环位置的截面在整个出水过程中是最小尺寸，水泵在出水时，水体经过活接接管位置的降压后缓流到挡流环位置，发生水体碰撞，第一过渡圆角的设置能够防止水体在挡水环和连接环的连接处出现回弹，减少水力损失，而第二过渡圆角的设置是为了经过挡水环聚流增压的水体能够更好的扩散到四通管内部，提高四通阀切换水体流道的效率。
作为优选，活接接管在锁紧凸台背对出口管的一侧的外表面形状为圆角正多边形，圆角正多边形的外接圆直径与压紧环的内径间隙配合。方便压紧环和锁紧凸台的压紧配合。
作为优选，进口管的内部设有两块对称设置的加强平板，两块加强平板的一侧分别与所在进口管内侧壁贴合，两块加强平板的另一侧水平平行设置。活接接管和水泵的连接位置确定，后续即使调整四通管的朝向也不会影响到活接接管和水泵，加强平板的设置能够加强进口管的强度，并且具有更好的汇流作用，此外，在水流从内螺纹段流动到进口管时，水流在横向上的降压强于纵向上的增压，因此气体更易从两侧开始扩散，实现对气体扩散路劲的规划，中部水体集中从挡水环流过，在提高气液分离效率的同时，减小水体的动能损失。
作为优选，密封件采用“O”形密封圈。密封作用可靠，在出口管和活接接管压紧时能够提供可靠的密封。
本发明的有益效果是：1、解决现有技术中接头与泵体螺纹连接造成的出水口朝向难以调节的问题，并且方便后期维护；2、用于智能泵中，智能泵需要涉及到排气功能，本发明所公开的出水结构具有更高的气液分离效率，能够提高排气的可靠性。

活接接管1包括伸入到出口管2内的进口管101，进口管101的内部设有两块对称设置的加强平板102，两块加强平板102的一侧分别与所在进口管101内侧壁贴合，两块加强平板102的另一侧水平平行设置。进口管101和锁紧凸台103之间形成密封台104，进口管101的端部设有第一过渡倒角105，锁紧凸台103朝向进口管101一端的外侧设有第二过渡倒角106，锁紧凸台103对应进口管101的端面的外径小于出口管2朝向锁紧凸台103一端的端面内径。密封件4设置在密封台104上，出口管2上设有对应密封台104的压紧斜面202。压紧斜面202为锥角为90度的圆台面。密封件4在安装到密封台104上时突出到密封台104的外部，方便压紧斜面202压紧密封件4起到可靠的密封作用。
出口管2是内部管路呈“十”字形的四通管，出口管2上设有接合段201，接合段201的外端设有用于与锁紧螺母5螺纹配合的外螺纹。接合段201和出口管2之间设有内径小于活接接管1最小内径的挡水环203。接合段201上设有连接挡水环203的连接环204，挡水环203的两端分别伸出到连接环204的外部，挡水环203的形状为圆环形，挡水环203朝向活接接管1的一端的外侧面上设有第一过渡圆角205，挡水环203背对活接接管1的一端的内侧面上设有第二过渡圆角206。
连接件采用锁紧螺母5，锁紧螺母5的外侧面形状为正八边形，方便通过工具拧动锁紧。锁紧螺母5和出口管2的接合段201通过螺纹连接，锁紧螺母5的一端设有用于压紧锁紧凸台103的压紧环501，压紧环501的内径小于锁紧凸台103的外径。活接接管1在锁紧凸台103背对出口管2的一侧的外表面形状为圆角正多边形，圆角正多边形的外接圆直径与压紧环501的内径间隙配合。
本申请在装配时，先在活接接管1上套装上锁紧螺母5，再将活接接管1通过外螺纹 段107螺纹连接至内螺纹段301，外螺纹段107的尾端预装弹性密封圈302，在内螺纹段301和外螺纹段107安装到位后，弹性密封圈302被压紧起到可靠的密封作用；然后在密封台104上预装弹性件，将进口管101插接至接合段201内部，此时可以调整出口管2的转动角度，出口管2可以在360度范围内任意转动，之后将锁紧螺母5和接合段201螺纹拧合，压紧环501穿过锁紧凸台103一侧的圆角正八边形后压紧锁紧凸台103，完成出口管2和活接接管1之间的压紧固定，因为出口管2可以相对活接接管1转动任意角度后再通过连接件锁紧连接，从而实现多通路的出口管2相对水泵3朝向的任意调节，使得智能泵整体成型后的更加美观，结构位置更加合理，同时也方便后期的维护调整。
