混砂车的压力液通过输送管路排出,需要连接的两个管路之间常常通过法兰或者焊接的方式密封连接。然而有时也需要管路围绕其轴线转动以带动带压流体,如此便需要连接的两个管路之间可以实现相对转动连接,而现有技术中的连接方式都是固定连接而不能实现连接的两个管路之间相对转动。
综上所述,如何实现两个管路之间的旋转连接,是目前本领域技术人员急需解决的问题。
实用新型内容
有鉴于此,本实用新型的第一个目的在于提供一种旋转接头装置,该旋转接头装置的结构设计可以实现两个管路之间的旋转连接,本实用新型的第二个目的是提供一种包括上述旋转接头装置的流体输送设备。
为了达到上述第一个目的,本实用新型提供如下技术方案:
一种旋转接头装置,包括:

优选地,上述旋转接头装置中,所述水封的与所述法兰接触的面和与内管接触的面均为阶梯面,所述法兰和内管均开设有与所述水封的阶梯面配合的阶梯槽。
优选地,上述旋转接头装置中,所述法兰的凸缘与所述外套环之间通过螺钉固定连接。
优选地,上述旋转接头装置中,所述法兰与所述外套环之间还设置有密封圈,且所述外套环上开设有能够容置所述密封圈的容置槽。
一种流体输送设备,包括如上述中任一项所述的旋转接头装置。
本实用新型提供的旋转接头装置,包括内管、外套环、轴套、压盖以及法兰。其中外套环套设在内管外侧,轴套套设在内管和外套环之间,且轴套均与内管的外壁和外套环的内壁接触,以减小摩擦力。压盖的形状为环形,且压盖与外套环的一端固定连接,即压盖设置在外套环沿着轴向的一端,并且内管的外壁上固定设置有凸起的定位挡圈,定位挡圈的两侧分别与压盖和轴套抵接。法兰与内管轴向排布,即法兰和内管沿着轴向并排设置且两者轴线重合,法兰的凸缘与外套环固定连接,并且内管与所述法兰的连接处设置有与两者的连接端均接触的水封,内管的连接端即为其靠近法兰的一端,法兰的连接端即为其靠近内管的一端,在内管的连接端和法兰的连接端之间设置有水封,且水封与内管的连接端和法兰的连接端均接触,且内管内部与法兰的内部连通。法兰的另一侧可以连接其它管路。
应用本实用新型提供的旋转接头装置时,由于外套环与内管之间设置有轴套,因此可以将内管固定。由于定位挡圈与压盖抵接,同时法兰与压盖固定连接且法兰与内管之间设置有水封,因此定位挡圈与法兰同时作用可以防止外套环与内管发生轴向移动。如此,可以驱动外套环转动,由于法兰与外套环固定连接,因此可以实现外套环和法兰共同转动且内管固定不转动,以此实现了法兰和内管相对转动,法兰可以连接其它管路,进而实现了其它管路与内管的相对转动。当然,也可以内管转动,法兰和外套环固定,或者内管和法兰同时相对转动。
为了达到上述第二个目的,本实用新型还提供了一种流体输送设备,该流体输送设备包括上述任一种旋转接头装置。由于上述的旋转接头装置具有上述技术效果,具有该旋转接头装置的流体输送设备也应具有相应的技术效果。

为了保证轴套4的内壁和内管3的外壁之间的密封性能,还可以在轴套4的内壁和内管3的外壁之间设置有密封圈6,以防止流体从轴套4的内壁和内管3的外壁之间泄漏。其中,可以在内管3的外壁上开设有能够容置密封圈6的容置槽,如此则可以将密封圈6置于容置槽中。进一步的,密封圈6可以为O型密封圈。
其中,水封5与法兰8接触的面和与内管3接触的面均为阶梯面,法兰8和内管3均开设有与水封5的阶梯面配合的阶梯槽。即水封5夹在法兰8和内管3之间,并且水封5与法兰8的连接端接触的面和与内管3的连接端接触的面均为阶梯面,内管3的连接端和法兰8的连接端上均开设有与水封5的阶梯面配合的阶梯槽,如此则可以将水封5置于内管3的连接端和法兰8的连接端的阶梯槽内,以此进一步防止流体从内管3和法兰8的连接处泄漏。当然,水封5的与法兰8的连接端接触的面和与内管3的连接端接触的面也可以为平面,在此不作限定。
