Description
Technical field
The utility model relates to the improvement of pipeline overpressure protector structure.
Background technique
Overpressure protector is when fluid pressure in the pipeline surpasses License Value, and liquid is discharged, and avoids the device of production development accident.
In chemical industry, it is larger that the pressure of liquid conducting pipes is affected by ambient temperature often, and it is particularly important for safety in production how to limit maximum pressure.Existing overpressure protector generally adopts Safety relief valve, though it can play certain protective action, uses convenient not, troublesome poeration.In addition, because the restriction of Safety relief valve structure, its outlet generally connects pipe special, and fluid can not be recycled.
Summary of the invention
The utility model is exactly for the problems referred to above, and a kind of pipeline overpressure protector easy to use, simple in structure is provided.
For achieving the above object, the utility model adopts following technological scheme, the utility model comprises the housing with import and outlet, its structure outline inlet is provided with the valve seat that the middle part has through hole, the through hole upper end is provided with the activity closeouts, activity closeouts upper end is provided with briquetting, is provided with elastic member between briquetting upper-end surface and the housing inner top side face.
As a kind of preferred version, briquetting described in the utility model upper end is provided with positioning rod, is provided with setting sleeve corresponding to positioning rod in the housing.
As another kind of preferred version, housing inside upper part described in the utility model is provided with the vertically regulating block of running fix, and described elastic member is arranged between briquetting upper-end surface and the regulating block lower end surface.
As another kind of preferred version, setting sleeve described in the utility model is arranged on the middle part of regulating block.
As another kind of preferred version, regulating block described in the utility model middle part is provided with groove, and elastic member is arranged between briquetting upper-end surface and the groove floor.
As another kind of preferred version, housing described in the utility model upper end links to each other with the housing top movable.
As another kind of preferred version, regulating block described in the utility model links to each other by screw thread with housing.
As another kind of preferred version, elastic member described in the utility model is spring.
Secondly, activity closeouts described in the utility model is spheroid.
In addition, briquetting described in the utility model lower end is provided with the inclined-plane corresponding to spheroid.
The utility model beneficial effect: the utility model is installed and used very convenient, working stability, effective, simple in structure by the cooperation between valve seat, activity closeouts, briquetting, the elastic member.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further.The utility model protection domain not only is confined to the statement of following content.
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model uses phase diagram.
Among the figure, 1 for import, 2 be that valve seat, 3 is transmission pipeline for reflux pipeline, 14 for outlet, 13 for regulating block, 12 for groove, 11 for setting sleeve, 10 for elastic member, 9 for positioning rod, 8 for housing, 7 for inclined-plane, 6 for briquetting, 5 for activity closeouts, 4.
Embodiment
As shown in the figure, the utility model comprises the housing 6 with import 1 and outlet 12, import 1 place is provided with the valve seat 2 that the middle part has through hole, the through hole upper end is provided with activity closeouts 3, activity closeouts 3 upper ends are provided with briquetting 4, are provided with elastic member 8 between briquetting 4 upper-end surfaces and the housing 6 inner top side faces.
Described briquetting 4 upper ends are provided with positioning rod 7, are provided with setting sleeve 9 corresponding to positioning rod 7 in the housing 6.Positioning rod 7 is used working stability with setting sleeve 9.
Described housing 6 inside upper part are provided with the regulating block 11 of vertically running fix, and described elastic member 8 is arranged between briquetting 4 upper-end surfaces and regulating block 11 lower end surfaces.Be convenient to the pressure of adjustable elastic parts 8 by regulating block 11.
Described setting sleeve 9 is arranged on the middle part of regulating block 11.
Described regulating block 11 middle parts are provided with groove 10, and elastic member 8 is arranged between briquetting 4 upper-end surfaces and groove 10 bottom surfaces.Elastic member 8 is placed in the groove 10 structural stability.
Described housing 6 upper ends link to each other with housing 6 top movable; Be convenient to housing 6 upper ends are pulled down, regulating block 11 is regulated.
Described regulating block 11 and housing 6 link to each other by screw thread; Easy to adjust.
Described elastic member 8 is spring.
Described activity closeouts 3 is spheroid.Spheroid can adopt steel ball.
Described briquetting 4 lower ends are provided with inclined-plane 5 corresponding to spheroid; Structural stability.
Described regulating block 11 upper ends are six square toes; Be convenient to turn adjusting.
Below in conjunction with description of drawings the utility model working procedure: at first the import 1 with housing 6 links to each other with transmission pipeline 14 outlets, and the outlet 12 of housing 6 links to each other with 13 imports of reflux pipeline.When in the pipeline during liquid superpressure, press activity closeouts 3, briquetting 4, elastic member 8 compressions, liquid enters in the housing 6 from the slit between activity closeouts 3 and valve seat 2 through holes, housing 6 is flowed out in outlet 12 through setting sleeve 9 middle parts, housing 6, flows back to storage tank through reflux again.When fluid pressure in the pipeline returns to when normal, under the effect of elastic member 8, activity closeouts 3 is blocked the through hole of valve seat 2.
