Structure, uses spherical arc surface clamping axially to position, eliminates snap ring spacing, and this flange can adapt to different regions Flange Standard
Install and need, greatly reduce cost, easy for installation, solid and reliable.But, the intensity of this flange and property easy for installation need into
One step improves.
Utility model content
The purpose of this utility model is for the problems referred to above, it is provided that a kind of pump loose flange.
For reaching above-mentioned purpose, this utility model have employed following technical proposal: a kind of pump loose flange, including method
Blue body, in described flange body and along some connecting holes that is circumferentially with of flange body, described flange body center sets
Having access opening, described access opening inwall to be provided with positioning step, described positioning step is provided with inner stopper.
In above-mentioned pump loose flange, described inner stopper is connected with the sidewall of positioning step.
In above-mentioned pump loose flange, the bottom of described inner stopper is circular arc bottom, and inner stopper and positioning step
Sidewall smoothly transit.
In above-mentioned pump loose flange, the thickness of described positioning step by away from inner stopper one laterally closer in
The side of seam is gradually increased, so that positioning step inwall forms bell mouth shape.
In above-mentioned pump loose flange, also include the location steel ring that can put in inner stopper.
In above-mentioned pump loose flange, described location steel ring has a breach.
In above-mentioned pump loose flange, the radian of location steel ring matches with the radian of inner stopper.
In above-mentioned pump loose flange, when positioning steel ring and putting in inner stopper, described location steel ring can be sent out
Life is shunk deformation thus is reduced the size of breach.
In above-mentioned pump loose flange, described connecting hole ovalize.
In above-mentioned pump loose flange, flange body uses casting technique disposal molding, and uses QT500-7 ball
Ink cast iron quality.
Compared with prior art, the utility model has the advantage of:
1, the design of inner stopper, facilitates and coordinates and import and export formation clamping location with position steel ring, easy to connect.
2, inner stopper limits steel ring position, location, and location steel ring is positioned into outlet, both can ensure that the intensity of Flange joint,
Flange can also rotate, and facilitates the installation of user.
3, employing forges the flange of technique, processes hell to pay；Using casting technique to hollow out the solid place of flange, strength reduction is bright
Aobvious, this utility model uses QT500-7 spheroidal graphite cast-iron, rigidity and tensile strength ratio to forge strong many of ferrum, more digs than solid place
Empty cast steel flange tensile strength is much higher.
Accompanying drawing explanation
Fig. 1 is the schematic diagram removing location steel ring of the present utility model；
Fig. 2 is the structural representation of location steel ring；
Fig. 3 is fundamental diagram of the present utility model.
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, import and export 101, groove 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, a kind of pump loose flange, including flange body 1, in described flange body 1 and along flange basis
Body 1 be circumferentially with some connecting holes 2, connecting hole 2 ovalize, connecting hole 2 is designed as ellipse, with facilitate with turnover water end (W.E.)
Pipeline connect, described flange body 1 center is provided with access opening 7, and described access opening 7 inwall is provided with positioning step 3, institute
The positioning step 3 stated is provided with inner stopper 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.When positioning steel ring 5 and putting in inner stopper 4, described location steel ring 5
Deformation can be shunk 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 the import and export 101 location steel passing in and out water body 100
Circle 5 radially positions, and imports and exports 101 and is provided with annular groove 102, determines location steel ring 5 external diameter with inner stopper 4, the most both
Can ensure that the intensity of Flange joint, flange can also rotate, and facilitates the installation of user.
Specific embodiment described herein is only to this utility model spirit explanation for example.This utility model institute
Belong to those skilled in the art described specific embodiment to make various amendment or supplement or use similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although the most more employing flange body 1, connecting hole 2, inner stopper 4, location steel ring 5, breach 6, access opening
7, pass in and out the terms such as water body 100, import and export 101, groove 102, but be not precluded from using the probability of other term.Use these
Term is only used to describe and explain essence of the present utility model more easily；It is construed as any additional limit
System is all contrary with this utility model spirit.
