Abstract
The invention belongs to the technical field of flange connection, and particularly relates to a guide pipe flange sealing connecting device with the adjustable peripheral direction. The connecting device comprises a flange disc (1), sealing rubber rings (2), a connecting flange disc (3), a fastening bolt (4) and a pressing flange disc (5). The adjustable flange sealing connecting device is mainly characterized in that the connecting flange disc (3) and the pressing flange disc (5) are designed independently in a split mode, and the problems that according to an original integrated design, compensation can not be conducted in the peripheral direction during sealing fixation, and the compression amount in a rubber gasket sealing mode can not be controlled easily are solved. The adjustable flange sealing connecting device adopts a double-rubber-ring sealing mode, is simple in structure and is high in sealing reliability.
Description
Technical field
The invention belongs to Flange joint technical field, particularly to a kind of circumferential adjustable conduit flange sealing and connecting device.
Background technology
Fuel duct generally adopts flange rubber cushion or the fixing connection of rubber sealing bolt, and ring flange circumference is compensated by this connected mode almost without regulating, and mounting process is poor, in fact it could happen that band stress installation question; Seal gasket decrement is difficult to control; The single rubber sealing of key position can not meet high reliability request, affects flight safety.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, circumference scalable, conduit flange sealing and connecting device that sealing reliability is high, can effectively solve the problems such as circumference cannot compensate, rubber cushion sealing means decrement is difficult to control to when conventional method orchid seals fixing.
Flange seal part adopts double density sealing groove rubber sealing, can control at optimum range by O-ring seal decrement, meet key position high reliability seal request, improve aircraft fuel system safety.
The technical scheme is that described connecting device includes ring flange 1, O-ring seal 2, mounting flange 3, fastening bolt 4, supported flange dish 5, mounting flange 3 straight tube one end outer wall is provided with lower seal groove cavity, O-ring seal 2 is installed in seal groove, ring flange 3 is provided with the flange panel of projection, supported flange dish 5 is fitted on the flange panel of projection, it is fixed together with ring flange 1 by fastening bolt 4, the seal face place of ring flange 1 and mounting flange 3 upper flange panel has seal groove, and is provided with O-ring seal 2.
This reality beneficial effect of the invention is: in the present invention, sealing flange and clamp flange dish adopt split type independent design, adopt double; two rubber sealing form, provide a kind of simple in construction, adjustable conduit flange sealing and connecting device that sealing reliability is high, can effectively solve the problems such as circumference cannot compensate, rubber cushion sealing means decrement is difficult to control to when conventional method orchid seals fixing, flange seal part adopts double density sealing groove rubber sealing, can O-ring seal decrement be controlled at optimum range, meet key position high reliability seal request.

Fig. 1 is explosive view of the present invention;
Fig. 2 is right view of the present invention;
Fig. 3 is invention A-A sectional view;
In figure: ring flange 1, O-ring seal 2, mounting flange 3, fastening bolt 4, supported flange dish 5.
Detailed description of the invention:
Accompanying drawings the specific embodiment of the present invention. The present invention is a kind of adjustable conduit flange sealing and connecting device, is made up of ring flange 1, two seals cushion rubber 2, mounting flange 3, fastening bolt 4 and supported flange dish 5. Ring flange 1 inner chamber is provided with seal groove, installs one sealing ring 2; Mounting flange 3 and supported flange dish 5 are adopted split type independent design by the present invention, mounting flange 3 straight tube end outer wall is provided with lower seal groove cavity, one sealing ring 2 is installed, it is deep in ring flange 1 inner chamber body, realize the double; two rubber sealing of two seals groove, can control, at optimum range, to improve sealing reliability by O-ring seal 2 decrement; Mounting flange 3 is compressed constraint by fastening bolt 4 by supported flange dish 5, is fastenedly connected with ring flange 1, the circumferentially adaptability adjustment of ring flange 1 and supported flange 5 compensates, it is to avoid band stress is installed, and improves mounting process.
