Abstract
The utility model provides an extensional stainless steel flange to solve the problem of pressure increase after pipes are connected. On the basis of a common flange plate, a trapezoid extension is arranged and can effectively increase the pipe output pressure, and extensional flanges with different calibers and meeting different requirements are produced according to the radius of pipes, so that the problem of connection between ring openings in different sizes of the pipes is solved. The extensional stainless steel flange comprises a plate body, a plate face, the trapezoid extension, a welding ring opening, bolt positioning holes and a plate body through hole, and is characterized in that the center of the plate body is provided with the plate body through hole; the bolt positioning holes are formed at the periphery of the plate body through hole; the surface of the plate body is provided with the plate face; the center of the plate face is provided with the trapezoid extension; the other end of the trapezoid extension is provided with the welding ring opening. The extensional stainless steel flange has the beneficial effects that the positive output pressure between the pipes can be improved, and the output pressure between the pipes is reduced conversely.
Description
Technical field
The utility model relates to the manufacture field of stainless steel product and instrument, relates in particular to a kind of extensional mode steel flange.
Background technique
Flange is the blue flange disk of call again.Flange is the interconnective part between pipe and pipe and between pipe and valve, for the connection between pipe end; Also the flange that has the equipment that is used in to import and export, for the connection between two equipment.Flange connects or flanged joint, refers to by flange, pad and bolt three and interconnects the releasable connection as one group of combined sealing structure.
But in the process of long-time utilization flange, it is found that the application of tangible common plane flange after flange connects is not very desirable, the connection that is too thin and pipe fitting of its problem flange plate also need to improve pressure in varying degrees, thereby and some pipe fittings diameter of needing in the course of the work to change pipe fitting increase Output pressure.
Model utility content
Problem to be solved in the utility model is to provide a kind of extensional mode steel flange, for addressing the above problem, improve the supercharging problem after connection between pipe fitting, on the original base of common flange plate, be provided with trapezoidal extension, change trapezoidal extension and can effectively increase pipe fitting delivery pressure, and can produce according to the reducing size of pipe fitting the extensional mode flange of the different bores of various demands, thereby solve the connectivity problem of different size circle mouth between pipe fitting.
The technical solution of the utility model is as follows: a kind of extensional mode steel flange, comprises disk body, card, trapezoidal extension, complete mouthful of welding, bolt positioning hole and disk body through hole; It is characterized in that described disk body center position is provided with disk body through hole, described disk body through hole is provided with bolt positioning hole around, and described disc surfaces is provided with card, and described card center position is provided with trapezoidal extension, and the described trapezoidal extension the other end is provided with welding circle mouthful.
Further, described disk body and trapezoidal extension are stainless steel resistance to compression material.
Further, described trapezoidal extension is trapezoidal circular arc structure.
The beneficial effects of the utility model are: the delivery pressure that can improve forward between pipe fitting, otherwise reduce the delivery pressure between pipe fitting, this product applicable from different pipe fittings between connection by being mutually permanently connected between disk body and trapezoidal extension and pipe fitting, realize, the size dimension that manufacturer also can need connect according to pipe fitting customizes the size of welding circle mouth in trapezoidal extension, thereby meet the connection between different size pipe fitting, and this product adopts high strength stainless steel material, durable not fragile.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is tangent plane schematic diagram of the present utility model.
Wherein: 1, disk body, 2, card, 3, trapezoidal extension,
4, welding circle mouthful, 5, bolt positioning hole, 6, disk body through hole.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made to brief description.
As shown in Figure 1, 2, a kind of extensional mode steel flange, comprises disk body 1, card 2, trapezoidal extension 3, complete mouthful 4 of welding, bolt positioning hole 5 and disk body through hole 6; It is characterized in that described disk body 1 center position is provided with disk body through hole 6, described disk body through hole 6 is provided with bolt positioning hole 5 around, described disk body 1 surface is provided with card 2, and described card 2 center positions are provided with trapezoidal extension 3, and described trapezoidal extension 3 the other ends are provided with welding circle mouth 4.
Described disk body 1 and trapezoidal extension 3 are stainless steel resistance to compression material.
Described trapezoidal extension 3 is trapezoidal circular arc structure.
Design and principle is installed: the design of trapezoidal extension 3 is for liquid is gathered to then output by trapezoidal extension 3 through disk body 1 time, this link is supercharging link, otherwise liquid refluence can be played the pressure-reducing function of liquid, it is installed principle and by disliking welding circle mouth 4 in trapezoidal extension 3, is fixed and welded together with corresponding size pipe fitting exactly, again by the disk body 1 corresponding flange plate equal with this product size in back and by the bolt positioning hole on two flange plate 5 mutual corresponding by special sealing pad by and special-purpose holding down bolt thereby two flange plate are connected together to the connection realizing between pipe fitting.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
