Fig. 2 is the structural representation of loose flange；
Fig. 3 is the structural representation of location steel ring.
In figure: flange body 1, connecting hole 2, positioning step 3, inner stopper 4, location steel ring 5, breach 6, access opening 7, turnover
Water body 100, adpting flange 101, cannelure 102.
Detailed description of the invention
The utility model is described in more detail with detailed description of the invention below in conjunction with the accompanying drawings.
As it is shown in figure 1, the turnover water column structure of a kind of MODEL VERTICAL MULTISTAGE PUMP, including turnover water body 100, described turnover water body
100 be respectively arranged at two ends with an adpting flange 101, described adpting flange 101 is respectively equipped with a loose flange, described
Loose flange include flange body 1, be circumferentially with some connecting holes 2 in described flange body 1 and along flange body 1,
Connecting hole 2 ovalize, connecting hole 2 is designed as ellipse, and to facilitate the pipeline with turnover water end (W.E.) to be connected, described flange is originally
Body 1 center is provided with access opening 7, and described access opening 7 inwall is provided with positioning step 3, and described positioning step 3 stops in being provided with
Mouth 4.As it is shown on figure 3, also include the location steel ring 5 that can put in inner stopper 4.
Above-mentioned flange uses casting technique disposal molding, and uses QT500-7 Nodular cast iron material.Rigidity and tension
It is strong many that strength ratio forges ferrum, more much higher than the cast steel flange tensile strength that solid place hollows out.
Inner stopper 4 is connected with the sidewall 3a of positioning step 3.The bottom of inner stopper 4 is circular arc bottom, and inner stopper 4 and location
The sidewall of step 3 smoothly transits, and improves the intensity of inner stopper 4.
The thickness of positioning step 3 is gradually increased by the side of the laterally closer inner stopper 4 away from inner stopper 4, this sets
Meter is the intensity in order to improve inner stopper 4 side, so that positioning step 3 inwall forms bell mouth shape, convenient connection is the most just
In processing inner stopper 4.
As in figure 2 it is shown, location steel ring 5 has a breach 6.As it is shown on figure 3, the cross section of location steel ring 5 is circular, should
Circular radian matches with the radian of inner stopper 4, and the edge of described adpting flange 101 is provided with and positions steel ring 5 and match
Cannelure 102, described inner stopper 4 and cannelure 102 surround formed stationary positioned steel ring 5 containing cavity.When location steel ring 5
When putting in inner stopper 4, described location steel ring 5 can shrink deformation thus reduce the size of breach 6.
As it is shown on figure 3, inner stopper 4 is designed as circular arc, flange body 1 and adpting flange 101 location passing in and out water body 100
Steel ring 5 radially positions, and adpting flange 101 is provided with cannelure 102, determines location steel ring 5 external diameter with inner stopper 4, so
Both can ensure that the intensity of Flange joint, flange can also rotate, and facilitates the installation of user.
