Abstract
The utility model relates to a detachable flange. A sealing washer is arranged between a fixed flange and a flange which is welded with a pipe. The outer side of the sealing washer is sheathed with a detachable flange and is connected by an axially connecting bolt. An inside diameter of the sealing washer is equal to an inside diameter of a connected pipe, an outer diameter of the sealing washer is smaller than a diameter of a hollowness of the detachable flange, and namely, the flange which is welded with the pipe and the sealing washer are arranged in the hollowness of the detachable flange. The utility model has the advantages of strong pressure resistance, good sealing performance, and convenient assembly and disassembly.
Description
Affiliated technical field
The flange that the utility model belongs to a kind of pipe connects, and specifically is a kind of detachable flange.
Background technique
Fixed flange connects on the existing pipe, and flange is fixing, and it is very inconvenient to install and remove extremely in the end of pipe, and the seal washer bearing capacity is poor, and easy to leak is changed inconvenient.
Summary of the invention
In order to overcome the deficiency that existing fixed flange connects inconvenient dismounting and easy to leak, the utility model provides a kind of detachable flange, makes it easy accessibility, good airproof performance.
The technological scheme that its technical problem that solves the utility model adopts is: fastening flange and and pipe be encased inside seal washer between welded flange; behind active flange of overcoat; connect with connecting bolt; the internal diameter of seal washer equates with joining two pipes together internal diameter; external diameter is less than active flange recess diameter; promptly with pipe welded flange and seal washer nest in active flange recess inboard; so not only seal washer is subjected to the active flange of periphery to surround protection; do not exposed to the open air; be difficult for aging; not by the bulging of pipe internal pressure; radially compression resistance also obviously strengthens, and does not need mobile pipe when changing seal washer, as long as axial connecting bolt is taken apart; active flange unclamps immediately, can easily the seal washer of changing be taken out and put into.
Good effect of the present utility model is active flange easy accessibility, and the seal washer bearing capacity is strong, and easy to leak is not changed conveniently.
Description of drawings
Fig. 1 is the utility model plan view.Among the figure: 1. take over, 2. fastening flange, 3. bolt, 4. active flange is 5. with pipe welded flange, 6. seal washer.
Embodiment
In Fig. 1, fastening flange (2) and and pipe welded flange (5) between be encased inside seal washer (a 6) active flange of overcoat (4) back and strain with axial turnbuckle (3), the internal diameter of seal washer (6) and institute take over (1) and equate with the ips of managing welded flange (5), the external diameter of seal washer (6) is less than the recess diameter of active flange (4), make seal washer (6) nest in the recess of active flange (4), do not exposed to the open air, be difficult for aging, not by bulging, so voltage endurance capability is strong, good airproof performance, as long as take axial turnbuckle (3) when changing seal washer apart, active flange (4) can unclamp easily, makes seal washer (6) take out and put into, and is very convenient.
Claims (2)
1, a kind of detachable flange is made up of flange, seal washer etc., it is characterized in that fastening flange and and pipe be encased inside seal washer between welded flange, connect with connecting bolt behind active flange of overcoat.
2, detachable flange according to claim 1 is characterized in that the internal diameter of seal ring equates with joining two pipes together internal diameter, and external diameter is less than active flange recess diameter, promptly with pipe welded flange and seal washer nest in the recess of active flange.
