Description
Technical field
The utility model relates to a kind of general pressurized vessel, is specifically related to a kind of diaphragm type pressure water storage equipment sealed structure.
Background technology
Existing pressure water storage equipment, having two kinds of common structures, one is that water butt main body is divided into first staving and second entire body, and between first staving and second entire body, pressing arranges elasticity interlayer, first staving and second entire body welding, above elasticity interlayer be water storage cavity, below be air storing cavity. Another kind is that water butt body interior is provided with a water storage bag communicated with water-in, and the space of water storage bag outside is air storing cavity, and water butt main body arranges the inlet mouth communicated with air storing cavity.
For the structure of the first pressure water storage equipment, owing to water butt is that first staving and second staving connect, and elasticity interlayer is pressed together between first staving and second staving, only top half staving and second staving bolt connect the power produced by elasticity interlayer pressing to existing pressing mode, elasticity interlayer is by, after power, its edge is easily deviate from from pressing; In addition, easily leak between first staving and second staving.
Practical novel content
The purpose of this utility model is to provide a kind of diaphragm type pressure water storage equipment sealed structure, and the good sealing effect of above-mentioned sealed structure, can prevent from easily leaking between first staving and second staving.
For achieving the above object, base case of the present utility model is as follows:
Diaphragm type pressure water storage equipment sealed structure, comprise upper barrel body, lower barrel body and elasticity interlayer, the lower surface of described upper barrel body is offered multi-ring annular groove, the cross section of this annular recesses is taper, the upper surface of described lower barrel body be provided with multi-turn respectively with the flange of multi-ring annular groove fit, each flange sleeve has the first sealing-ring; Described elasticity interlayer is pressed together between upper barrel body lower surface and lower barrel body upper surface.
The principle of this scheme: in this scheme, before use, is filled with pressurized gas in advance in lower barrel body, during use, in upper barrel body, inject water, in the process of water filling, elasticity interlayer is extruded distortion, and elasticity interlayer moves from upper barrel body toward lower barrel body side, until completing water filling.
The advantage of this scheme is: in this scheme, the cross section of upper barrel body lower surface annular recesses is taper, the upper surface of lower barrel body is provided with the flange coordinated with annular recesses, upper barrel body is that inclined-plane coordinates with lower barrel body matching part, the contact surface of both junctions is big, so the area of the trim formed is big, sealing better effects if; In addition, when elasticity interlayer is pressed together between the upper barrel body of this scheme and lower barrel body, the outer rim of elasticity interlayer is engaged in annular recesses, and such elasticity interlayer is by, after power, its edge just is difficult to deviate from from pressing, and the pressing of elasticity interlayer is effective.
Prioritization scheme 1, to the further optimization of base case, the bottom of described annular recesses is provided with the 2nd sealing-ring.Elasticity interlayer is pressed together in annular recesses, is provided with the 2nd sealing-ring and then can ensure the sealing property between elasticity interlayer and annular recesses.
Prioritization scheme 2, to the further optimization of base case, the cone angle size that the cross section of described annular recesses is formed is 20-25 °. In use finding, when above-mentioned angle is arranged at the cone angle that the cross section of annular recesses is formed, the pressing between upper barrel body and lower barrel body is tight, and sealing property is good.
Prioritization scheme 3, to the further optimization of base case, prioritization scheme 1,2 arbitrary, described upper barrel body and lower barrel body inner side and outer side are all bolted. After upper barrel body and lower barrel body inner side and outer side are all compressed by bolt, can ensure to connect closely between upper barrel body and lower barrel body, Leakage prevention.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model diaphragm type pressure water storage equipment sealed structure embodiment;
Fig. 2 is the structural representation of upper barrel body and lower barrel body pressing place in the utility model diaphragm type pressure water storage equipment sealed structure embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: upper barrel body 10, flange 11, first sealing-ring 12, lower barrel body 20, annular recesses 21, the 2nd sealing-ring 22, elasticity interlayer 30.
Embodiment is substantially as shown in Figure 1: a kind of diaphragm type pressure water storage equipment sealed structure, comprise upper barrel body 10, lower barrel body 20 and elasticity interlayer 30, the lower surface of upper barrel body 10 is offered multi-ring annular groove 21, the cross section of this annular recesses 21 is taper, the upper surface of lower barrel body 20 is provided with the flange 11 that multi-turn coordinates respectively with multi-ring annular groove 21, and each flange 11 overcoat has the first sealing-ring 12; Elasticity interlayer 30 is pressed together between upper barrel body 10 lower surface and lower barrel body 20 upper surface. Upper barrel body 10 and lower barrel body 20 inner side and outer side are all bolted. After upper barrel body 10 and lower barrel body 20 inner side and outer side are all compressed by bolt, can ensure to connect closely between upper barrel body 10 and lower barrel body 20, Leakage prevention.
In the present embodiment, the bottom of annular recesses 21 is provided with the 2nd sealing-ring 22. Elasticity interlayer 30 is pressed together in annular recesses 21, is provided with the 2nd sealing-ring 22 and can ensure the sealing property between elasticity interlayer 30 and annular recesses 21.
