Abstract
The utility model provides a flange sealing structure. An inspection hole which is added to a flange is used for detecting the seal leakage and the problem that the seal leakage cannot be timely detected is solved. According to the technical scheme, the flange with a seal leakage inspection hole is characterized in that a sealing washer is arranged between the flange and a connecting part; one section of the flange, which is towards the sealing washer, is provided with a flange grove; one side of the sealing washer, which is towards the flange, is matched with the flange inside the flange groove; one section of the connecting part, which is towards the sealing washer, is provided with a connecting part groove; one side of the sealing washer, which is towards the connecting part, is matched with the connecting part inside the connecting part groove; a position in the flange, which is arranged at an annular center of the flange groove, is provided with an inspection hole in a drilling mode; the inspection hole is communicated with a detection hole; the flange, the connecting part and the sealing washer achieve sealing due to fastening through bolt.
Description
Technical field
The utility model relates to a kind of flange seal.
Background technique
Flange is interconnective part between pipe and pipe, 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.Flange connects easy to use, can bear larger pressure.In industrial pipeline, the use that flange connects is very extensive.The sealing surface of flange generally has the forms such as annular groove face sealing surface, convex face sealing surface, whole plane sealing surface, male and fomale(M&F) sealing surface, tongue and groove sealing surface, annular groove face sealing surface complexed metal ring pad normal be used in all higher operating modes of high temperature, high pressure or the two, in Petroleum Production and petroleum refining industry, especially come into one's own, purposes is just more and more extensive.But the situation that flange in use also there will be seal failure to leak, detects that for the medium such as inflammable, explosive, poisonous, harmful the leakage of sealing is very important in time.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of flange sealing structure, has increased peep hole on flange, for detecting in time the leakage of finding sealing, solves the problem that seal leakage can not detect in time.For solving the above problems, the utility model has adopted following scheme: a kind of flange with seal leakage inspection socket, it is characterized in that: between described flange and link, be provided with seal washer, described flange is provided with flange groove towards a section of seal washer, described seal washer coordinates with flange in flange groove towards a side of flange, described link is provided with link groove towards a section of seal washer, described seal washer coordinates with link in link groove towards a side of link, described flange is drilled with peep hole in the ring center that is positioned at flange groove, peep hole is communicated with detection hole.Flange, link and seal washer are by the fastening realization sealing of bolt.
As preferably, the slot cross-section of described flange groove is trapezoidal.
As preferably, detect hole thread mill drilling outside flange, carry out Leak testtion for setting pressure Detecting element.
As preferably, seal washer Huan center processing intercommunicating pore, for the pressure in connected sum balance flange groove and link groove.
The utility model provides a kind of flange sealing structure, has increased seal leakage peep hole on flange, for detecting in time the leakage of finding sealing, solves the problem that seal leakage can not detect in time.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
With reference to the accompanying drawings the utility model is described further below: a kind of flange arrangement that detects mouth with seal leakage, comprise flange (1), the link (2) being connected with flange (1), it is characterized in that: between described flange (1) and link (2), be provided with seal washer (3), described flange (1) is provided with flange groove (4) towards a section of seal washer (3), described seal washer (3) coordinates with flange (1) in flange groove (4) towards a side of flange (1), described link (2) is provided with link groove (5) towards a section of seal washer (3), described seal washer (3) coordinates with link (2) in link groove (5) towards a side of link (2), described flange (1) is drilled with peep hole (6) in the ring center that is positioned at flange groove (4), peep hole (6) is communicated with detection hole (7), flange (1), link (2) seals by the fastening realization of bolt (8) with seal washer (3).
Detect hole (7) at flange (1) outside thread mill drilling, carry out Leak testtion for setting pressure Detecting element.
Seal washer Huan center processing intercommunicating pore (9), for the pressure in connected sum balance flange groove (4) and link groove (5).
When flange is during at work due to situation generation seal leakages such as bolt looseness, pressure medium variation, seal washer inefficacies, dielectric leakage is during to cavity in the middle of seal washer (3) and flange groove (4), can cause that the pressure in cavity changes, by peep hole (6) with detect hole (7) by pressure conduction to being arranged on the Detecting element detecting on hole (7), change the leakage situation that can judge in time sealing by pressure.
Claims (4)
1. the flange with seal leakage peep hole, comprise flange (1), the link (2) being connected with flange (1), it is characterized in that: between described flange (1) and link (2), be provided with seal washer (3), described flange (1) is provided with flange groove (4) towards a section of seal washer (3), described seal washer (3) coordinates with flange (1) in flange groove (4) towards a side of flange (1), described link (2) is provided with link groove (5) towards a section of seal washer (3), described seal washer (3) coordinates with link (2) in link groove (5) towards a side of link (2), described flange (1) is drilled with peep hole (6) in the ring center that is positioned at flange groove (4), peep hole (6) is communicated with detection hole (7), flange (1), link (2) seals by the fastening realization of bolt (8) with seal washer (3).
2. a kind of flange according to claim 1, is characterized in that: the slot cross-section of described flange groove (4) is trapezoidal.
3. a kind of flange according to claim 1, is characterized in that: detect hole (7) at flange (1) outside thread mill drilling, carry out Leak testtion for setting pressure Detecting element.
4. a kind of flange according to claim 1, is characterized in that: seal washer Huan center processing intercommunicating pore (9), and for the pressure in connected sum balance flange groove (4) and link groove (5).
