Abstract
The utility model provides a connecting sealing device for flanges, and relates to the connecting sealing device for the flanges in a liquid or ore pulp delivering pipeline and a pulp containing tank. The connecting sealing device for the flanges is characterized in that a steel-plate cushion block is arranged between two flanges which need to be connected, the thickness of the steel-plate cushion block is smaller than the diameter of a circular sealing rubber bar, and the width of the steel-plate cushion block is smaller than the width of each flange. Connecting bolts are used to connect the flanges and the steel-plate cushion block tightly, the circular sealing rubber bar arranged in a gap among the two flanges and the steel-plate cushion block is compressed, the liquid or the ore pulp in the pipeline and the tank is sealed, the connecting sealing device for the flanges is more reliable compared with an original method that a sealing rubber cushion is arranged between two flanges, and the connecting sealing device for the flanges can be used for a long time without leakage, and is simple in manufacturing and low in cost.
Description
Technical field
The utility model relates to a kind of liquid or ore pulp delivery duct and Sheng stock tank case flange connecting sealing device.
The pipeline of now conveying and contain fluid or ore pulp, tank joint seal of flanges are to add a seal rubber pad between two flanges, connect with bolt afterwards.
Background technique
The pipeline of now conveying and contain fluid or ore pulp, tank joint seal of flanges are to add a seal rubber pad between two flanges, and rear with the bolt connection, there are following two aspect problems in this sealing means:
1, add a seal rubber pad between two flanges, it is flexible that flange connects, and uses rear pipeline slightly to have displacement to leak for long-distance transmission pipeline is long-term;
2, for large scale, non-machine tooling flanged surface, working surface can produce the flexing distortion behind welded flange, sealing area is large, strong lower than the Asia, sealing difficulty causes connecting bolt to arrange intensive, and where leaks and just need tight this place's bolt, but can not be with the bolt overtorquing, otherwise seal rubber pad can damage by pressure.
Summary of the invention
Reveal and easily damage by pressure the problem of inefficacy for the flange seal that solves existing pulp conveying and hold, the utility model provides a kind of flange connecting sealing device.For achieving the above object, the technical solution adopted in the utility model is: flange (4) is welded on the housing (2), unworn liner (1) is bonded on the housing (2), steel plate cushion block (6) intermittent point welding is on any flange (4), and steel plate cushion block (6) outside is concordant with flange (4) outside, circular seal adhesive tape (3) is placed between two flanges (4) and steel plate cushion block (6) in the gap, with bolt (5) with two flanges (4), steel plate cushion block (6) and circular seal adhesive tape (3) connect compression.Wherein, steel plate cushion block (6) thickness is less than circular seal adhesive tape (3) diameter, and width is less than flange (4) width.The sealing device can not only play good sealing, and can easily change Stamping Steel Ribbon, guarantees the sealing effect of seal arrangement in the being dismounted for multiple times process.
Description of drawings
Shown in Figure 1 is the utility model flange front view, and its shape can be circle, rectangle or other arbitrary shape, but opening, also can be closed;
Shown in Figure 2 is the utility model A-A section shape.
Wherein: 1, unworn liner, 2, housing, 3, circular seal adhesive tape 4, flange, 5, bolt, 6, the steel plate cushion block.
Embodiment
Aforesaid liquid or ore pulp delivery duct and the concrete assembly relation of Sheng stock tank case flange connecting sealing device are exactly mode of execution of the present utility model.Its enforcement (production) process is: flange (4) is welded on the housing (2), unworn liner (1) is bonded on the housing (2), steel plate cushion block (6) Width flange is narrow, it by intermittent point welding on any flange (4), and steel plate cushion block (6) outside is concordant with flange (4) outside, circular seal adhesive tape (3) is placed between two flanges (4) and steel plate cushion block (6) in the gap, with bolt (5) with two flanges (4), steel plate cushion block (6) and circular seal adhesive tape (3) connect compression.
Claims (2)
1. one kind relates to liquid or ore pulp delivery duct and Sheng stock tank case flange connecting sealing device, it is characterized in that flange (4) is welded on the housing (2), unworn liner (1) is bonded on the housing (2), steel plate cushion block (6) intermittent point welding is on any flange (4), and steel plate cushion block (6) outside is concordant with flange (4) outside, circular seal adhesive tape (3) is placed between two flanges (4) and steel plate cushion block (6) in the gap, with bolt (5) with two flanges (4), steel plate cushion block (6) and circular seal adhesive tape (3) connect compression.
2. described flange connecting sealing device according to claim 1 is characterized in that steel plate cushion block (6) thickness less than circular seal adhesive tape (3) diameter, and width is less than flange (4) width.
