特殊单立管排水系统的上部特制原理

特殊单立管排水系统的起步是从特制配件开始的,特制配件分上部特制配件和下部特制配件两种。上部特制配件用以排水横支管与排水立管的连接,同时解决横支管水流与立管水流的相互干扰问题。下部特制配件用以排水立管与排水横干管的连接,同时解决立管底部的水跃、壅水和空气通道中阻问题,上部特制配件和下部特制配件是互相配套的。

Special single riser drainage system is the beginning of the beginning of the special parts, special parts of the upper part of the special accessories and special accessories under the two. In order to solve the mutual interference between the branch pipe and the riser pipe, the upper part is used to drain the connection between the branch pipe and the drainage riser. The lower part is specially used for draining the connection between the vertical pipe and the drain dry pipe, and simultaneously solves the problem of the water jump, the backwater and the air passage resistance in the bottom of the vertical pipe.

上部特制配件的两项功能中,连接排水横支管和排水立管是基本功能,解决两种水流的相互干扰是主要功能。为了防止水流的相互干扰,采取的措施有两种方式:

The upper part of the special accessories of the two functions, the connection of the drainage branch pipe and drainage riser is the basic function, to solve the mutual interference of the two water flow is the main function. In order to prevent the interference of water flow, there are two ways to take measures:

1 分流。用内挡板、内管或改变水流进入方向等办法使排水横支管水流和排水立管水流在水流方向一致之前不相遇。苏维托的档板,环流器、环旋器的内管和侧流器的进水方向改变就基于这一理念。

1 shunt. With the inner baffle, the inner pipe or changing the direction of water flow into the direction and so on, so that the drainage branch pipe flow and drainage riser water flow in the same direction before the flow. Baffle Suwito, circulation device, ring rotary device of the inner tube and the inlet side flow direction change is based on this idea.

2 旋流。使排水横支管与管件的连接不是正向接入,而以切线方向接入。以形成横支管水流的旋流状态,从而保持立管中心的空气芯,旋流也有采用导流叶片,管内壁或管件内壁螺旋线(螺旋肋或螺旋体)来造成的。前者如旋转进水型管件,后者如AD型细长接头,AD型小型接头,CA型接头,CB型接头,管旋器等。另一种旋流是在管件内设置螺旋肋,也有很好的效果,如漩流降噪接头。

2 cyclone. The connection between the drainage transverse branch pipe and the pipe fittings is not a positive access, but is connected with a tangent direction. In order to form the vortex state of the water flow of the transverse branch pipe, the air core of the vertical tube center is maintained, and the vortex flow is also caused by the adoption of the guide vanes, the inner wall of the pipe or the inner wall of the pipe line (spiral rib or spiral body). The former, such as rotary inlet pipe fittings, the latter, such as AD type slender joints, AD type small joints, CA type connectors, CB type connectors, such as rotary tube. Another is the spiral rib is arranged in the cyclone tube, also have very good effect, such as swirling joint noise reduction.
