Abstract
An anti-static flange connection disc comprises two flanges which are symmetrically assembled in buckling mode. The end portions of the outsides of the two flanges are respectively connected with pipelines on the same sides, a sealing gasket is assembled between the two flanges in clamping mode, and a metal piece communicating the two flanges is installed on the edge positions of the two flanges. The metal piece communicates the two flanges which are mutually insulated originally, so that all parts in a whole acetylene production line are communicated, the flange connection disc is connected with the ground, static can be effectively input in the ground, and production safety is guaranteed. Further, the metal piece is fixed through bolts in the existing flanges, no other parts are added, so that the flange connection disc is convenient to maintain, assemble and disassemble.
Description
Technical field
The utility model belongs to acetylene safety production technique field, especially a kind of antistatic flange land.
Background technique
Acetylene is a kind of important chemical material; Be mainly used in freeze metal and organic synthesis, it is processed by calcium carbide and water reaction, and general technology is: add calcium carbide in the water in the controllable reaction jar; The acetylene that generates is transported to compression set by the road, after pressurization, is charged in the acetylene cylinder.In process of production, for fear of the blast of acetylene, each equipment and between pipeline all through conductor cable ground connection; But a large amount of flange plate that use in the connection of pipeline, its structure is: comprise two flange plate of symmetrical spiral-lock, the end in these two flange plate outsides connects the pipeline of homonymy respectively; In the middle of two flange plate, clamp gasket seal to guarantee the sealing of gas circuit; But, effectively enter the earth, but because conductor cable is all installed in the both sides of flange plate through ground wire in order to guarantee electrostatic energy because gasket seal is that insulating material is processed; Its complex structure is not easy to installation and maintenance.
The model utility content
The purpose of the utility model is to overcome the deficiency of existing technology, and a kind of antistatic flange land simple in structure, easy to use is provided.
The technological scheme that the utility model is taked is:
A kind of antistatic flange land; Two flange plate that comprise symmetrical spiral-lock; The end in these two flange plate outsides connects the pipeline of homonymy respectively; In the middle of two flange plate, clamp gasket seal, it is characterized in that: a tinsel with two flange plate conductings is installed by the edge at two flange plate.
And the two ends kink of said tinsel is sleeved on the two ends of the bolt of two flange plate of locking respectively.
And said tinsel uses copper or aluminium.
And said tinsel outer surface coats installs a skin.
The advantage and the good effect of the utility model are:
In the utility model, a tinsel with two flange plate conductings is installed by the edge of two flange plate, and this tinsel makes two flange plate conductings of original mutually insulated; Make the equal conducting of various piece in the whole acetylene line; Use total ground connection promptly can effectively static be imported the earth like this, guaranteed production safety, and the bolt on the existing flange plate of the fixedly employing of this tinsel; Can not increase other parts, safeguard, dismounting is all very convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit the protection domain of the utility model with following embodiment.
A kind of antistatic flange land; As shown in Figure 1; Two flange plate 2 that comprise symmetrical spiral-lock; The end in these two flange plate outsides connects the pipeline 1 of homonymy respectively, in the middle of two flange plate, clamps gasket seal 4, and the innovation of the utility model is: a tinsel 5 with two flange plate conductings is installed by the edge at two flange plate.
In the present embodiment, in order to simplify the installation of tinsel, kink is all made at the two ends of tinsel, these two kinks are sleeved on the two ends of the bolt 3 of two flange plate of locking respectively.Tinsel uses copper or aluminium to wait until the metal that a performance is good.
For fear of tinsel owing to receive the decline of oxidation, the conductive capability that causes of corrosion; Coat installation one outer 6 at the tinsel outer surface; This skin coats the surface of tinsel; And tinsel and the contacted inner surface of flange outer rim also protected, effectively avoided the oxidation and the corrosion of tinsel itself, improved conductive capability.
In the utility model, a tinsel with two flange plate conductings is installed by the edge of two flange plate, and this tinsel makes two flange plate conductings of original mutually insulated; Make the equal conducting of various piece in the whole acetylene line; Use total ground connection promptly can effectively static be imported the earth like this, guaranteed production safety, and the bolt on the existing flange plate of the fixedly employing of this tinsel; Can not increase other parts, safeguard, dismounting is all very convenient.
Claims (4)
