Abstract
The utility model discloses a flange device provided with a seal seam allowance, which includes an upper flange and a lower flange arranged symmetrically in the vertical direction, wherein an annular groove provided with a rectangular cross section is arranged at the bottom of the upper flange and takes the center of the upper flange as the reference, an annular bulge is arranged on the lower flange and corresponds to the annular groove on the upper flange, and the space between the annular groove and the annular bulge is filled with seal silica gel in order to enhance the seal performance between the flanges. Through additionally arranged the seam allowance form groove and bulge between the upper flange and the lower flange, the flange seal performance is greatly improved, the traditional gasket seal is replaced, the rough positioning action is played at the same time, mounting and dismounting are convenient, and the seal silica gel between the groove and the bulge enhances the seal performance of the flange device, so that the flange device is more suitable for connecting large-diameter and high-pressure pipe fittings.
Description
Technical field
The utility model relates to a kind of flange apparatus of high sealing performance.
Background technique
In the technique known field, flange connects and is made up of a pair of flange, a pad and several bolt and nuts, and pad is placed between two flange facings; Behind the fastening nut; Specific pressure on the gasket surface produces distortion after reaching certain numerical value, and fills up uneven place on the sealing surface, makes to connect tight the leakage to reach the purpose of sealing; It is loosening that but the mode of this mechanical seal is easy to generate; The effect of influence sealing, sealing effect is not satisfactory when the big caliber pipe fitting of high pressure connects simultaneously, is easy to generate the problem of Lou pressing.
The model utility content
The technical problem that the utility model will solve is: the flange apparatus that a kind of good seal performance is provided.
The utility model solves the technological scheme that its technical problem adopted: a kind of flange apparatus with sealing seam; Comprise upper and lower symmetrically arranged upper flange and lower flange respectively; In the bottom of described upper flange and with the center of upper flange is that benchmark is provided with the rectangular annular groove of cross section, on described lower flange and corresponding to the annular groove on the upper flange, is provided with annular protrusion.
Further, in order to strengthen the sealability between flange, the utility model is filled with sealing silica gel between described annular groove and annular protrusion.
The beneficial effect of the utility model is: the utility model is through setting up the groove and the convexity of seam shape between last lower flange; Make the sealability of flange improve greatly; To substitute traditional gasket seal, the coarse localization effect of also having held concurrently simultaneously is easy for installation and removal; Between groove and convexity, fill and seal the sealability that silica gel has strengthened described flange apparatus especially, its pipe fitting that can more can adapt to big caliber, high pressure is connected.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1. upper flange, 1-1. annular groove, 2. lower flange, 2-1. annular protrusion.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of flange apparatus of the utility model as shown in Figure 1 with sealing seam; Comprise upper and lower respectively symmetrically arranged upper flange 1 and lower flange 2; In the bottom of described upper flange 1 and with the center of upper flange 1 is that benchmark is provided with the rectangular annular groove 1-1 of cross section; On described lower flange 2 and corresponding to the annular groove 1-1 on the upper flange 1, be provided with annular protrusion 2-1, between described annular groove 1-1 and annular protrusion 2-1, be filled with sealing silica gel.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
Claims (2)
1. one kind has the flange apparatus that seals seam; Comprise upper and lower symmetrically arranged upper flange (1) and lower flange (2) respectively; It is characterized in that: in the bottom of described upper flange (1) and with the center of upper flange (1) is that benchmark is provided with the rectangular annular groove of cross section (1-1), goes up and is provided with annular protrusion (2-1) corresponding to the annular groove (1-1) on the upper flange (1) at described lower flange (2).
