Detailed description of the invention
The embodiment of the invention discloses a kind of open sealing structure of metallic filter, its open upper cover easy and simple to handle, save time.The embodiment of the invention also discloses a kind of metallic filter, it applies above-mentioned open sealing structure, opens the easy and simple to handle, quick of upper cover.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1-2, the embodiment of the present invention provides a kind of open sealing structure of metallic filter, it comprises lower cover 100 and is removably fixed on the upper cover 200 on lower cover 100, wherein, lower cover 100 comprises and being fixedly connected with and the main body 12 be communicated with and the projection 11 be fixedly connected with this main body 12 with this metallic filter, and above-mentioned projection 11 forms draw-in groove with aforementioned body 12; The edge of upper cover 200 is provided with the protuberance 21 coordinated with above-mentioned draw-in groove, and this protuberance 21 is fastened on above-mentioned draw-in groove place.
In the open sealing structure of the metallic filter that the embodiment of the present invention provides, upper cover 200 is fastened on the draw-in groove place of upper cover 200 by protuberance 21, protuberance 21 only need be made when opening to deviate from by draw-in groove, by structure that bolt makes upper and lower covers be fixedly connected with in prior art, which obviate the multiple bolt of dismounting, open the easy and simple to handle of upper cover 200, and save time, be convenient to increase work efficiency.
In addition, the open sealing structure place of the metallic filter that the embodiment of the present invention provides also has high voltage bearing effect, its highest high pressure bearing 4.0MPa.
In the open sealing structure of the metallic filter that above-described embodiment provides, the mode that upper cover 200 can be placed through rotation disassembles by lower cover 100.Concrete, draw-in groove is set to multiple, and its bottom surface is arc surface; The number of protuberance 21 is set to the number being no less than draw-in groove, and adjacent protuberance 21 distance is circumferentially not less than draw-in groove length circumferentially.During assembling, after making the indentation, there of adjacent tabs 21 on upper cover 200 corresponding with projection 11, place it on lower cover 100, then, rotate upper cover 200, to make protuberance 21 screw in draw-in groove, thus upper cover 200 is fixed on lower cover 100.Preferably, above-mentioned protuberance 21 is evenly arranged.Concrete, the number of above-mentioned protuberance 21 is set to identical with draw-in groove, and number is 2.
Because in metallic filter use afterwards its, gas is high pressure conditions, for the ease of the gases at high pressure in metallic filter being discharged before opening upper cover 200, in the open sealing structure of the metallic filter that the present embodiment provides, upper cover 200 is provided with the valve 23 for being vented, and it is communicated with the inside of lower cover 100.During application, slowly open valve 23, originally the opening opened of valve 23 is less, and the gases at high pressure sprayed by valve 23 are less, and the liquid of metallic filter inside can be avoided to be sprayed by valve 23; Subsequently, the angle opened of valve 23 increases gradually, but partial high pressure gas is discharged by valve 23, and the pressure of metallic filter inside reduces, and the gas that a large amount of pressure is higher is discharged by valve 23, and the liquid of metallic filter inside can be avoided equally to spray; To sum up, compared to the mode of discharging gases at high pressure by extracting pin common in prior art, internal liquid ejection when the open sealing structure that the present embodiment provides can be avoided discharging gases at high pressure, eliminates the hidden danger of aforesaid liquid harm staff and surrounding devices.
Further, do not discharge gas in metallic filter in order to avoid workman and directly open upper cover, in the open sealing structure of the metallic filter that the present embodiment provides, projection 11 is provided with groove, valve 23 comprises spanner, and it is against in groove when valve 23 is closed, deviate from by groove gradually while valve 23 is opened.In the open sealing structure of this metallic filter, valve 23, upper cover 200 and lower cover 100 form safety interlock, if without discharge gases at high pressure, upper cover 200 is pinned by the spanner of valve 23, and it cannot rotate, and namely cannot open, workman's maloperation can be prevented, eliminate safe hidden trouble.
In order to further optimize technique scheme, in the open sealing structure of the metallic filter that the present embodiment provides, the tubular that upper cover 200 is closed in one end, its openend is stretched in the port of lower cover 100, and the side above-mentioned openend being pressed close to lower cover 100 is provided with the seal groove of band sealing ring 300; Wherein, protuberance 21 is near above-mentioned openend.
In the open sealing structure of the metallic filter that the present embodiment provides, the gap place between upper cover 200 and lower cover 100 is provided with sealing ring 300, and the sealing that upper cover 200 is connected with lower cover 100 is guaranteed.
Concrete, in the open sealing structure of the metallic filter that above-described embodiment provides, also comprise the handle 22 for rotary upper cover 200, it is fixed on upper cover 200.Preferably, above-mentioned handle 22 is provided with through hole, for inserting the clubs such as reinforcing bar, is convenient to staff by promoting above-mentioned club with rotary upper cover 200.
In the open sealing structure of the metallic filter that above-described embodiment provides, the mode that upper cover 200 can also be placed through pull disassembles by lower cover 100.Accordingly, the number of projection 11 is set to 2, and namely the number of draw-in groove is set to 2, and the bottom surface of draw-in groove is set to plane, and the bottom surface of 2 draw-in grooves is set to parallel; Upper cover 200 is set to rectangle, and the protuberance 21 on it inserts in draw-in groove.Concrete, above-mentioned upper cover 200 covers the port of lower cover 100, and is provided with sealing gasket between itself and lower cover 100.
The embodiment of the present invention also provides a kind of metallic filter, which is provided with opening, and opening part is provided with hermetically-sealed construction, wherein, and the open sealing structure that hermetically-sealed construction provides for above-described embodiment.
