Abstract
The utility model provides a lightningproof and antistatic flange bridging device which comprises two flanges, a red copper piece, a pair of flange clamps and a hexagonal bolt. The red copper piece is fixedly mounted between the flanges in a bridging manner, the flange clamps cover the red copper piece, and the hexagonal bolt penetrates the flange clamps and fixes the red copper piece and the flange clamps on the flanges. The lightningproof and antistatic flange bridging device is simple in structure, easy in popularization and capable of effectively preventing accumulation of static charge; in the process of engineering construction, flange mounting and static grounding can be completed at one step, so that repeated labor or the phenomenon that part of the flanges is not connected with static grounding wires due to negligence is reduced, and the objectives of eliminating static electricity and reducing workload are achieved truly.
Description
Technical field
The utility model is specifically related to a kind of flange lightning protection anti electrostatic crossover assembly.
Background technique
At present, the a lot of units of Oilfield Company are carrying out the flange cross-over connection work in inflammable and explosive place, but there is no ready-made flange cross-over connection production standard, if for high pressure flange jumper be pressed in nut may damage by pressure below copper sheet, fastening force not, problem that bolt length is inadequate, and the release that will stop production could be implemented.
Model utility content
The purpose of this utility model is for solving above-mentioned deficiency, and a kind of flange lightning protection anti electrostatic crossover assembly is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of flange lightning protection anti electrostatic crossover assembly, comprise flange, copper sheet, the 1 pair of flange clip and hex head bolt, copper sheet cross-over connection is fixedly mounted between two flanges, 1 pair of flange clip covers on copper sheet, and hex head bolt passes flange clip and copper sheet and flange clip are fixed on flange.
The utility model also has some technical characteristicss like this:
Described hex head bolt or for long pin screw rod.
The utlity model has following useful effect:
The utility model is simple in structure, be easy to promote, can effectively prevent gathering of static charge, in engineering construction process, flange is installed with electrostatic grounding and can a step be completed, reduce the duplication of labour or miss the phenomenon of static ground wire because carelessness causes part flange, really having reached the object of eliminating static and reducing workload.
Brief description of the drawings
Fig. 1 is of the present utility model without clamp device structural representation;
Fig. 2 is the clamp device structural representation that has of the present utility model;
Fig. 3 is the apparatus structure schematic diagram of belt length foot bolt of the present utility model.
Wherein, 1, flange, 2, copper sheet, 3, flange clip, 4, hex head bolt, 5, long pin screw rod.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
Embodiment 1
A kind of flange lightning protection anti electrostatic crossover assembly, comprise flange 1,2,1 pair of flange clip 3 of copper sheet and hex head bolt 4, copper sheet 2 cross-over connections are fixedly mounted between two flanges 1,1 pair of flange clip 3 covers on copper sheet 2, hex head bolt 4 is through flange clip 3 and copper sheet 2 and flange clip 3 are fixed on flange, described hex head bolt 4 or be long pin screw rod 5.
This device is mainly for high pressure flange, and other mesolow flange also can adopt.
By specific embodiment, the utility model is had been described in detail above, but these not form restriction of the present utility model.In the situation that not departing from the utility model principle, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection domain of the present utility model.
