The main TV structure schematic diagram of the open sealing structure of the metallic filter that Fig. 1 provides for the embodiment of the invention;
The plan structure schematic diagram of the open sealing structure of the metallic filter that Fig. 2 provides for the embodiment of the invention;
Wherein, among Fig. 1-Fig. 2:
The specific embodiment
The embodiment of the invention discloses a kind of open sealing structure of metallic filter, its open loam cake easy and simple to handle, save time.The embodiment of the invention also discloses a kind of metallic filter, it has used above-mentioned open sealing structure, opens the easy and simple to handle, quick of loam cake.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
See also Fig. 1-2, the embodiment of the invention provides a kind of open sealing structure of metallic filter, it comprises lower cover 100 and removably is fixed on loam cake 200 on the lower cover 100, wherein, lower cover 100 comprises with this metallic filter and being fixedly connected with and the main body 12 that is communicated with and the projection 11 that is fixedly connected with this main body 12, and above-mentioned projection 11 forms draw-in grooves with aforementioned body 12; The edge of loam cake 200 is provided with the protuberance 21 that cooperates 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 invention provides, loam cake 200 is fastened on the draw-in groove place of loam cake 200 by protuberance 21, only need make protuberance 21 by deviating to get final product in the draw-in groove when opening, the structure that by bolt upper and lower covers is fixedly connected with in the prior art, it has avoided a plurality of bolts of dismounting, open the easy and simple to handle of loam cake 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 invention provides also has high voltage bearing effect, its highest high pressure that bears 4.0MPa.
In the open sealing structure of the metallic filter that above-described embodiment provides, loam cake 200 can be set to by the rotation mode by disassembling on the lower cover 100.Concrete, draw-in groove is set to a plurality of, and its bottom surface is arc surface; The number of protuberance 21 is set to be no less than the number of draw-in groove, and adjacent protuberance 21 is not less than draw-in groove along circumferential length along circumferential distance.During assembling, after the indentation, there that makes adjacent protuberance 21 on the loam cake 200 and projection 11 are corresponding, place it on the lower cover 100, then, rotation loam cake 200 so that protuberance 21 screws in the draw-in grooves, thereby is fixed on the lower cover 100 loam cake 200.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 its interior gas was high pressure conditions after metallic filter used, for the ease of loam cake 200 is front discharges the gases at high pressure in the metallic filter opening, in the open sealing structure of the metallic filter that the present embodiment provides, loam cake 200 is provided with the valve 23 for exhaust, the internal communication of itself and lower cover 100.During application, slowly open valve 23, originally the opening opened of valve 23 is less, and is less by the gases at high pressure of valve 23 ejections, can avoid the liquid of metallic filter inside to be sprayed by valve 23 places; Subsequently, the angle of opening of valve 23 increases gradually, but the part gases at high pressure are discharged by valve 23 places, the pressure decreased of metallic filter inside, and the gas that a large amount of pressure are higher is discharged by valve 23 places, can avoid equally the liquid ejection of metallic filter inside; To sum up, the mode that pin is discharged gases at high pressure is extracted in common passing through in the prior art, the hidden danger that aforesaid liquid endangers staff and surrounding devices was eliminated in the internal liquid ejection when open sealing structure that the present embodiment provides can be avoided discharging gases at high pressure.
Further, do not discharge gas in the metallic filter and directly open loam cake for fear of the workman, 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 the groove when valve 23 is closed, and deviates from gradually by groove when valve 23 is opened.In the open sealing structure of this metallic filter, valve 23, loam cake 200 and lower cover 100 form safety interlock, if without the discharging gases at high pressure, loam cake 200 is pinned by the spanner of valve 23, and it can't rotate, and namely can't open, can prevent workman's maloperation, eliminate safe hidden trouble.
In order further to optimize technique scheme, in the open sealing structure of the metallic filter that the present embodiment provides, loam cake 200 is the tubular of end sealing, its openend stretches in the port of lower cover 100, and the side of pressing close to lower cover 100 on the above-mentioned openend is provided with the seal groove with 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 place, slit that loam cake 200 and lower cover are 100 is provided with sealing ring 300, and loam cake 200 is guaranteed with the sealing that lower cover 100 is connected.
Concrete, in the open sealing structure of the metallic filter that above-described embodiment provides, also comprising the handle 22 for rotary upper cover 200, it is fixed on the loam cake 200.Preferably, above-mentioned handle 22 is provided with through hole, is used for inserting the clubs such as reinforcing bar, is convenient to the 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, loam cake 200 can also be set to mode by pull by disassembling on the 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 the plane, and the bottom surface of 2 draw-in grooves is set to parallel; Loam cake 200 is set to rectangle, and the protuberance 21 on it inserts in the draw-in groove.Concrete, above-mentioned loam cake 200 covers the port of lower cover 100, and itself and 100 of lower covers are provided with sealing gasket.
The embodiment of the 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.
