Abstract
The utility model discloses a flange for connecting pipe fittings, and aims at providing a low-cost and conveniently assembled flange for connecting the pipe fittings. The technical scheme of the flange has the key points that a groove is formed in a matching surface of a first flange, convex ribs are both arranged on two relative side walls of the groove, a convex block is arranged on the matching surface of a second flange, clamping slots which are matched with the convex ribs are formed in two relative lateral surfaces of the convex block, the second flange slips in the groove through the convex block and then is in contradictive connection with the first flange, and the convex ribs are placed in the clamping slots. According to the utility model, the first flange is connected with the second flange, so that bolt holes in the first flange and the second flange can be reduced to reduce the number of bolts required during mounting so as to lower the production cost, and further facilitate operation.
Description
Technical field
The utility model relates to pipeline installation fitting field, and more particularly, it relates to a kind of flange plate for connection pipe fitting.
Background technique
Flange plate is applied to when pipeline connects be found everywhere, and by a pair of flange of working in coordination, pipeline well can be connected.As a rule, between a pair of flange plate, be to add flange gasket and by corresponding mounting hole is set, and then by realizing connection each other such as links such as bolts.Stable for two flange plate are connected firmly, conventionally need a plurality of bolts to be connected and fixed, be not easy to two flange plate assemblings, also increased the manufacture cost of flange plate simultaneously.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of low cost, is convenient to the flange plate for connection pipe fitting of assembling.
For achieving the above object, the utility model provides following technological scheme: a kind of flange plate for connection pipe fitting, comprise the first flange plate and the second flange plate that can work in coordination, described the first flange plate and the second flange plate are equipped with mounting hole, the fitting surface of described the first flange plate is provided with groove, the two side that described groove is relative is equipped with convex tendon, the fitting surface of described the second flange plate is provided with projection, the bi-side that described projection is relative are provided with the draw-in groove suitable with convex tendon, described the second flange plate is connected with the first flange plate after slippage in groove through projection, described convex tendon is placed in draw-in groove.
By adopting technique scheme, fitting surface at the first flange plate is provided with groove, the fitting surface of described the second flange plate is provided with projection, projection enters from groove one end, the first flange plate and the second flange plate relatively rotate, projection slides in groove, the convex tendon of groove two side is placed in the draw-in groove of projection, the first flange plate is connected with the second flange plate is inconsistent, can reduce the first flange plate and the second flange plate upper bolt hole, and then the quantity of the bolt needing while reduce installing, reduced cost of production, simultaneously convenient operation.
The utility model is further set to: the cross section of described convex tendon is semi-circular shape, and the cross section of described draw-in groove is U-shaped shape.
By adopting technique scheme, simplified the structure of the first flange plate and the second flange plate, be convenient to manufacture.
The utility model is further set to: described groove is two, and is circumferentially uniformly distributed around mounting hole central axis.
By adopting technique scheme, reasonable layout groove, makes the first flange plate be connected firm stable more with the second flange plate more.
Accompanying drawing explanation
Fig. 1 is that the utility model is a kind of for the structural representation under the flange plate separated state of connection pipe fitting;
Fig. 2 is that the utility model is a kind of for the sectional view under the flange plate mated condition of connection pipe fitting;
Fig. 3 is A partial enlarged drawing in Fig. 2.
The 1, first flange plate in figure; 11, groove; 111, convex tendon; 2, the second flange plate; 21, projection; 211, draw-in groove; 3, mounting hole.
Embodiment
Referring to figs. 1 through Fig. 3, a kind of flange plate for connection pipe fitting of the utility model is described further.
The end face that wherein said fitting surface is in contact with one another while being described the first flange plate and the cooperation of the second flange plate.
A kind of flange plate for connection pipe fitting, comprise the first flange plate 1 and the second flange plate 2 that can work in coordination, described the first flange plate 1 and the second flange plate 2 are equipped with mounting hole 3, it can be annular groove that the fitting surface of described the first flange plate 1 is provided with its further groove of groove 11(), the relative two side of described groove 11 is equipped with convex tendon 111, in order to make the first flange plate 1 be connected firm stable more with the second flange plate 2, described groove 11 can be two, and be circumferentially uniformly distributed around mounting hole 3 central axis, groove 11 is distributed more reasonable, the fitting surface of described the second flange plate 2 is provided with projection 21, the relative bi-side of described projection 21 are provided with the draw-in groove 211 suitable with convex tendon 111, described the second flange plate 2 is connected with the first flange plate 1 after the interior slippage of groove 11 through projection 21, described convex tendon 111 is placed in draw-in groove 211, in order to have simplified the structure of the first flange plate 1 and the second flange plate 2, be convenient to manufacture, the cross section of described convex tendon 111 is semi-circular shape, the cross section of described draw-in groove 211 is U-shaped shape, certainly draw-in groove 211 can be also dovetail groove,
Fitting surface at the first flange plate 1 is provided with groove 11, the fitting surface of described the second flange plate 2 is provided with projection 21, projection 21 enters from groove 11 one end, the first flange plate 1 and the second flange plate 2 relatively rotate, projection 21 is in the interior slip of groove 11, the convex tendon 111 of groove 11 two sides is placed in the groove of projection 21, make the first flange plate 1 and second flange plate 2 is inconsistent is connected, can reduce the first flange plate 1 and the second flange plate 2 upper bolt holes, and then the quantity of the bolt needing while reduce installing, reduced cost of production, simultaneously convenient operation.
