Abstract
The utility model discloses a sealing device of a box, which is characterized in that one or two sealing interfaces of the box are respectively with a slot in the form fit with an aerated aeration aircushion for arranging the aeration aircushion. The sealing device for the water inlet and outlet of a box adopts an aeration aircushion as seal and arranges the aeration aircushion in the water inlet and outlet on the wall of the box. The sealing device has simple structure, less elements, low processing accuracy, simple installment and maintenance, stable performance, high reliability, better sealing effect, low production cost, long service life and wide application.
Description
Technical field
The utility model relates to a kind of seal arrangement, and particularly a kind of sealing of casing and casing advance the seal arrangement of drain opening.
Background technique
At present, the seal arrangement of existing casing adopt mostly sealing plate, structure such as diaphragm seal, seal ring, stuffing box gland, seal valve, rubber pad, locking mechanism, screw mechanism, but these seal arrangements all have its strong point and advantage, but all be not suitable for the interface scope of sealing big, have certain various type, often be in carrying and the dynamical state that moves in the sealing of casing.
The model utility content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, propose a kind of simple in structure, requirement on machining accuracy is low, convenient for installation and maintenance, sealability stable and the seal arrangement of the casing of effective, low cost of manufacture and long service life.
Main technical schemes of the present utility model is to adopt inflatable air cushion to seal between the sealing interface of casing, promptly be provided with respectively on two of the casing sealing interfaces or be provided with on sealing interface therein with inflation after the groove that is used to place inflatable air cushion that matches of inflatable air cushion shape, inflatable air cushion is positioned over the groove the inside between the sealing interface of casing.When needs seal, inflatable air cushion integral body is positioned in the groove between the sealing interface of casing, sealing interface with casing closes up then, and inflatable air cushion is full of gas after fastening with casing is outside, at this moment inflatable air cushion is full of in the groove that the back of combining closely between the sealing interface that can fully closely be full of described casing behind the gas forms.The fastening force of expansive force by the inflatable air cushion between the sealing interface of casing and casing outside makes between the sealing interface of casing and realizes sealing like this.
The seal arrangement that advances drain opening that the utility model is used for casing also adopts inflatable air cushion to seal, the same with above-mentioned reason, with inflatable air cushion be placed on box body wall in drain opening, when needs seal, inflatable air cushion is full of gas, utilizes inflatable air cushion to realize the sealing of casing at the expansive force in the drain opening of box body wall.
The utility model is simple in structure, used part is few, requirement on machining accuracy is low, convenient for installation and maintenance, have the characteristics of stable performance, reliability height, sealability and effective, cheap for manufacturing cost, long service life and applied range, in addition, the chest that seals with seal arrangement of the present utility model can carry out the ground dismounting of full position, be convenient to chest is consigned, have stronger use value.
Description of drawings
Fig. 1 is two cross-sectional view that seal when respectively groove being set on the interfaces of the seal arrangement of a kind of casing described in the utility model,
Fig. 2 is the sealing cross-sectional view that the box body wall of the seal arrangement of a kind of casing described in the utility model advances drain opening.
Embodiment:
Be described in further detail below in conjunction with the seal arrangement of the drawings and specific embodiments a kind of casing described in the utility model.As shown in Figure 1, the utility model be provided with respectively on the sealing interface 1 and 2 of casing with inflation after the groove 6 that is used to place inflatable air cushion 3 that matches of inflatable air cushion 3 shapes; Perhaps be provided with on the sealing interface 1 of casing and 2 one of them sealing interface with inflation after the groove 6 that is used to place inflatable air cushion 3 that matches of inflatable air cushion 3 shapes, inflatable air cushion 3 is positioned in the groove 6 between the sealing interface 1 and 2 of casing.
When needs seal, earlier the sealing interface 1 and 2 of casing close up in conjunction with and the outside fastening back of casing is full of gas to inflatable air cushion 3, the fastening force of expansive force by the inflatable air cushion 3 between the sealing interface 1 and 2 of casing and casing outside makes between the sealing interface 1 and 2 of casing and realizes sealing like this.
The seal arrangement that advances drain opening that the utility model is used for casing also adopts inflatable air cushion to seal, as shown in Figure 2, enter drain opening 5 the insides with what inflatable air cushion 3 was placed on box body wall 4, when needs seal, inflatable air cushion 3 is full of gas, utilizes inflatable air cushion 3 to realize the sealing of casing at the expansive force that enters drain opening 5 the insides of box body wall 4.
The profile of inflatable air cushion 3 of the present utility model can change according to the shape of the sealing interface 1 of casing and 2 and the shape of advancing drain opening of casing, as being long strip, square, rectangular, circle, triangle, polygonal and irregular polygon or the like arbitrary shape.The cross section of inflatable air cushion also can be an arbitrary shape.
The utility model is not limited to the foregoing description; to those skilled in the art, any conspicuous improvement that the foregoing description of the present utility model is made or change can not exceed the embodiment of the present utility model that only illustrates by way of example and the protection domain of claims.
