Description

流体分流器Fluid splitter 技术领域Technical field
本发明创造涉及流体连接件领域,具体涉及将流体从主管路分配到支路的连接装置。The present invention relates to the field of fluid connectors, and more particularly to a connection device for distributing fluid from a main line to a branch.
背景技术Background technique
气体、液体输送管道广泛应用于石油、化工等工业领域。在生产应用中,主管路或容器内的流体往往需要连接多个支线管路,用以分配流体,以满足工业需求,实现样本检测、流体性能指标测试、循环散热等目的。气源分配器在工业领域中应用最为广泛,中国专利CN102788246A公开了一种气源分配器,这种气源分配器是集中安装的启动仪表与气体总管相连接的中间桥梁,它可以方便控制各管路的通断。中国专利CN104180115A认为在先专利的连接方式会导致容器壁过厚,这就导致整个装置笨重,因此作出改进,发明了薄壁型流体分流器。中国专利CN104180115A公开的这种流体分流器,容器壁薄、重量轻,但是加工制造工艺欠佳,在这种装置中,穿插固定销时必须从容器内部一端进行,穿插完毕后,再进行容器端盖的焊接,这种装配工艺,装配速度慢,而且最后焊接容易破坏导致密封失效,成品率低。Gas and liquid pipelines are widely used in petroleum, chemical and other industrial fields. In production applications, fluids in the main road or container often need to be connected to multiple branch lines to distribute fluids to meet industrial needs, to achieve sample testing, fluid performance testing, and heat dissipation. The gas source distributor is the most widely used in the industrial field. Chinese patent CN102788246A discloses a gas source distributor, which is a middle bridge connecting the centrally installed starter instrument and the gas main pipe, which can conveniently control each The continuity of the pipeline. The Chinese patent CN104180115A considers that the connection method of the prior patent causes the container wall to be too thick, which causes the entire device to be cumbersome, and thus improvements have been made to invent the thin-wall type fluid splitter. The fluid shunt disclosed in Chinese Patent No. CN104180115A has a thin wall and a light weight, but the processing and manufacturing process is not good. In this device, the fixing pin must be inserted from the inner end of the container, and after the insertion is completed, the container end is performed. The welding of the cover, the assembly process, the assembly speed is slow, and finally the welding is easily broken, resulting in seal failure and low yield.

Problem solution
技术解决方案Technical solution
一种流体分流器,包括容器、多个阀门、多个接头、多个扣合件和多个密封件;接头与阀门、容器连接;阀门控制管路的通断;所述容器包括至少一个用于连接主管路的流体主通道,还包括设置在容器的圆柱壁上、与接头连接的圆孔;接头大致呈圆管状,具有贯通的中心孔,第一端具有用于连接阀门的阴螺纹, 阴螺纹处形成中心孔,该中心孔沿着接头轴向贯通至接头第二端,中心孔在第二端的直径小于阴螺纹处的直径,使得中心孔在靠近第二端形成环状平台,接头第二端端面上设置有环形凹槽;扣合件包括阴螺纹部、薄壁部、外沿部、突起部和中心孔,扣合件的中心孔贯通阴螺纹部、薄壁部和外沿部;扣合件的阴螺纹部和薄壁部依次穿过接头、密封件和容器圆孔,在轴向、相向方向上的外力作用下,薄壁部塑变塌陷、并向薄壁部径向向外鼓起,形成突起部,使扣合件外沿部的下缘抵顶在接头的环状平台上、突起部抵顶在环绕圆孔的容器内壁上,实现接头与容器形成轴向夹紧,并将密封件封闭在凹槽内。A fluid flow divider includes a container, a plurality of valves, a plurality of joints, a plurality of fasteners and a plurality of seals; a joint is connected to the valve and the container; the valve controls the opening and closing of the pipeline; and the container includes at least one The fluid main passage connecting the main pipe further comprises a circular hole which is arranged on the cylindrical wall of the container and connected to the joint; the joint is substantially round and has a through hole, and the first end has a female thread for connecting the valve. Forming a central hole at the female thread, the central hole extending through the joint axially to the second end of the joint, the diameter of the central hole at the second end being smaller than the diameter of the female thread, such that the central hole forms an annular platform near the second end, the joint An annular groove is disposed on the end surface of the second end; the fastening component comprises a female thread portion, a thin wall portion, an outer edge portion, a protrusion portion and a center hole, and the central hole of the fastening member penetrates the female thread portion, the thin wall portion and the outer edge The female threaded portion and the thin-walled portion of the fastening member sequentially pass through the joint, the sealing member and the circular hole of the container, and under the external force in the axial direction and the opposite direction, the thin-walled portion is plastically collapsed and is thinned toward the thin-walled portion.

进一步的,为了提高扣合件与容器内壁的摩擦力,防止扣合件轴向松动,在薄壁部外壁设置有纹路或凸起,以加大突起部与容器内部的摩擦力。Further, in order to improve the friction between the fastening member and the inner wall of the container, the fastening member is prevented from being loosened in the axial direction, and the outer wall of the thin portion is provided with a grain or a protrusion to increase the friction between the protrusion and the inside of the container.
进一步的,为了提高扣合件与接头的摩擦力,防止接头与扣合件轴向松动,外沿部的下缘设置有纹路或凸起,环状平台上也设置有纹路或凸起。Further, in order to improve the friction between the fastening component and the joint, the joint and the fastening component are prevented from being loosened axially, and the lower edge of the outer edge portion is provided with a grain or a protrusion, and the annular platform is also provided with a grain or a protrusion.
流体分流器还包括设置在容器上的用于清扫的泄放接口。The fluid splitter also includes a bleed port for cleaning on the container.
进一步的,接头第二端端面是平面,扣合件塑变时压迫容器壁也发生塑变,使容器外壁贴合在接头第二端面上。Further, the end surface of the second end of the joint is a flat surface, and the wall of the pressing container is also plastically deformed when the fastening member is plasticized, so that the outer wall of the container is attached to the second end surface of the joint.
作为另一种方案,接头第二端面也可以是与容器壁半径相当的圆弧面。Alternatively, the second end face of the joint may also be a circular arc surface having a radius corresponding to the wall of the container.

The specific installation method of the joint is: the male threaded end 521 of the mandrel 52 of the clamping device 50 and the fastening member The female thread 332 of the female thread portion is screwed, and the screwing direction is as shown in FIG. 6, and the folded front end 333 of the fastening member is sequentially passed through the joint 20, the sealing member 40, the circular hole 18, and the annular sealing member is made. 18 is embedded in the recess 26, and the sleeve end 511 is abutted against the upper edge 312 of the fastener, and then the force F1 is applied to the sleeve 51, and a force F2 is applied to the mandrel 52 to make the fastener The axial compression causes the thin portion 32 to bulge radially outward to form a protrusion 322. As the forces F1 and F2 are gradually increased, the protrusion 322 abuts against the inner wall of the container 10 and presses the inner wall of the container to be plasticized. Sexually fits over the end face 23 of the joint 20, and finally the mandrel 52 and the female threaded portion 33 are unscrewed, as shown in Fig. 10 to complete the installation of a joint. Install the remaining connectors in the same way as above. Finally, the valve 60 is mounted to the female thread of the joint 20 to provide the fluid splitter shown in FIG.
实施例2Example 2
一种流体分流器,与实施例1中的流体分流器基本相同,不同之处在于,接头第二端面23是与容器中段11半径相当的圆弧面。扣合件30轴向压缩塑变过程中,容器中段11外壁不塑变就与第二端面23自然吻合对接。 A fluid splitter is substantially identical to the fluid splitter of Embodiment 1 except that the second end face 23 of the joint is a circular arc surface that is commensurate with the radius of the midsection 11 of the vessel. During the axial compression molding process of the fastening component 30, the outer wall of the middle section 11 of the container is naturally abutted with the second end surface 23 without being plastically deformed.
