Abstract
The invention discloses a hexagon bolt for a pipe flange. The hexagon bolt for the pipe flange comprises a screw and a nut, wherein the screw and the nut are made of alloy steel, threads are arranged on the surface of the screw, a clamping groove is formed in the bottom of the screw, the nut is a regular hexagon, a sealing disc is arranged between the nut and the screw, the diameter of the sealing disc is 12 mm, and the sealing disc is detachably connected with the nut. The hexagon bolt is simple in structure and convenient to manufacture, is conveniently applied to connection of the pipe flange and is convenient to mount and dismount, meanwhile the sealing performance of a pipe is also ensured, the usage safety is improved, and the hexagon bolt is excellent in practical performance and novel in design, is a very good innovation scheme and has wide market promotion prospect.
Description
Technical field
The present invention relates to a kind of link, particularly relate to a kind of pipe flange hex head bolt.
Background technique
Flange is the blue flange disk of call or bead again.Flange is interconnective part between pipe and pipe, for the connection between pipe end; Also the flange that the equipment that is used in is imported and exported is had, for the connection between two equipment, as speed reducer flange.Flange joint or flanged joint, refer to and be interconnected releasable connection as one group of combined sealing structure by flange, pad and bolt three.Piping flange means the flange of pipe arrangement in tube equipment, is used in import and export flange equipment meaning equipment.Perforation on flange, bolt makes two flanges be close to.Liner containment is used between flange.Flange divides be threaded (screwed connection) flange, welded flange and clip flange.Flange is all use in pairs, and low pressure pipeline can use an acting flange, and four kilograms with the use welded flange of upward pressure.Add sealing gasket between two panels flange plate, then use bolton.The flange thickness of different pressures is different, and the bolt that they use is also different.Water pump and valve, when being connected with pipeline, the local of these equipment facilities, also makes corresponding flange shape, also referred to as Flange joint.Every union piece using bolt connection simultaneously to close at two planar perimeter, be generally all called " flange ", as the connection of ventilation duct, this class part can be called " flange type part ".But this connection is the local of an equipment, as the connection of flange and water pump, just bad water pump " flange type part ".More small-sized as valve etc., can cry " flange type part ".But current pipe flange often adopts bolt in the process connected, and bolt is easy dismounting after installing, and can adopt the situation of leakage, there is certain potential safety hazard, so there is deficiency to actual use.
In sum, for the defect of prior art, need pipe flange hex head bolt especially, to solve the deficiencies in the prior art.
Summary of the invention
The deficiency that in using for pipe flange in prior art, bolt exists, and bring very large inconvenience in the work of reality, the present invention proposes pipe flange hex head bolt, structure is simple, novel in design, the while of easy-to-mount, also guarantee to address the deficiencies of the prior art the sealability that pipeline connects.
To achieve these goals, the present invention realizes by the following technical solutions:
Pipe flange hex head bolt, comprise screw rod, nut, screw rod and nut all adopt alloyed steel, and the surface of screw rod is provided with screw thread, and the bottom of screw rod is provided with draw-in groove, nut is regular hexagon, be provided with sealed disc between nut and screw rod, the diameter of sealed disc is 12mm, adopts detachable connection between sealed disc and nut.
Further, the below of described draw-in groove is provided with drill bit, adopts detachable connection between drill bit and screw rod.
Further, the length of described screw rod is 40mm, adopts one-body molded between screw rod and nut.
The invention has the beneficial effects as follows: this product structure is simple, easy to make, apply the connection of piping flange easily, and not only easy disassembly, also ensure that the sealability of pipeline simultaneously, enhance safety in utilization, practicability is excellent, modern design, is a kind of well innovation scheme, has very much marketing prospect.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is pipe flange hex head bolt structural representation of the present invention.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
See Fig. 1, pipe flange hex head bolt, comprise screw rod 110, nut 100, screw rod 110 and nut 100 all adopt alloyed steel, and the surface of screw rod 110 is provided with screw thread 120, and the bottom of screw rod 110 is provided with draw-in groove 140, nut 100 is regular hexagon, be provided with sealed disc 130 between nut 100 and screw rod 110, the diameter of sealed disc 130 is 12mm, adopts detachable connection between sealed disc 130 and nut 100.In addition, the below of draw-in groove 140 is provided with drill bit 150, adopts detachable connection between drill bit 150 and screw rod 110, and the length of screw rod 110 is 40mm, adopts one-body molded between screw rod 110 and nut 100.
The present invention is effective is: structure is simple, easy to make, applies the connection of piping flange easily, and not only easy disassembly, also ensure that the sealability of pipeline simultaneously, enhance safety in utilization, practicability is excellent, modern design, is a kind of well innovation scheme, has very much marketing prospect.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
