Abstract

The utility model provides a ventilating duct quick-opening sealing device, which comprises two face flanges which are connected with each other and a support fastener. The two face flanges are sealed with a carbon seal ring, and are permanently connected with a short joint, respectively. One of the short joints is permanently connected with a hinge arm; the other end of the hinge arm is flexibly connected to a hinge axis. The hinge axis is arranged on a shaft support which is permanently connected with the other short joint. The utility model makes use of a hinge for connection, and changes the sealing mode, is convenient for mounting and dismounting connected pipes, reduces sealing bolts; the carbon sealing mode is adopted to ensure sealing effect; the overall structure of the device is rational; the hinge arm has high strength, is invulnerable to deformation, has long performance life, and is convenient for dismantlement and overhaul which can be completed by one person easily.

Description

Ventilation duct is driven seal arrangement soon

Technical field:

The utility model relates to a kind of seal arrangement, especially relates to a kind of pipestill for heat carrier ventilation duct and drives seal arrangement soon.

Background technique:

In ventilation duct, usually adopt flange to be connected with the equipment body joint, install high temperature resistant asbestos rope additional and seal, the change in location because pipeline has living space, the face-flange connecting bolt is more in addition, geometric distortion is big, dismounting is difficulty very, is difficult for during installation aiming at tapped hole, and poorly sealed, cause sealing medium to leak outside, very dangerous.

The model utility content:

Technical problem to be solved in the utility model provides a kind of convenience, good sealing effect, ventilation duct rational in infrastructure, long service life of removing and installing and drives seal arrangement soon, to overcome the defective that prior art exists.

The technical solution of the utility model is: comprise two face-flanges that are connected, support fastening piece, two face-flanges adopt the carbon seal ring sealing, two fixedly connected short circuit heads of face-flange difference, be fixedly connected with hinge arms on one of them short circuit head, the other end of hinge arms is movably connected on the hinge axis, on the bracing strut that hinge axis is located at another short circuit head is fixedlyed connected.

The utility model utilizes hinge to connect, change seal form, make things convenient for the dismounting and the installation of connecting line, reduced sealing bolt, adopt the form of graphite grazing, guarantee sealing effect, device reasonable integral structure, hinge arms intensity height, not yielding, long service life, a people just can finish dismounting and service work, and is very convenient.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the right elevation of Fig. 1.

Embodiment:

With reference to Fig. 1, Fig. 2, the utility model comprises two face-flanges that are connected 2, supports fastening piece 7, two face-flanges adopt carbon seal ring 6 sealings, two face-flanges weld a short circuit head 1 respectively, be welded with hinge arms 5 on one of them short circuit head, the other end of hinge arms 5 is movably connected on the hinge axis 4, and hinge axis is fixed on the bracing strut 3 of fixedlying connected with another short circuit head.

During use, the short circuit head end that is provided with bracing strut is fixed in ventilation duct, during dismounting, as long as take the support fastening piece apart, the short circuit head that connects hinge arms is rotated counterclockwise around hinge axis takes apart, very convenient, a people just can finish.

Claims

1. a ventilation duct is driven seal arrangement soon, comprise two face-flanges that are connected, support fastening piece, it is characterized in that: two face-flanges adopt the carbon seal ring sealing, two fixedly connected short circuit heads of face-flange difference, be fixedly connected with hinge arms on one of them short circuit head, the other end of hinge arms is movably connected on the hinge axis, on the bracing strut that hinge axis is located at another short circuit head is fixedlyed connected.
