Abstract
The utility model discloses a kind of pipeline pressure-resisting plate, comprise disc, described disc center is a hemispherical groove, two circular arc draw-in grooves are offered in disc upper edge, described hemispherical groove upper surface sets gradually three layers of buffer strip by edge to center portion, each buffer strip comprises four and half arc grooves respectively, and described four and half arc grooves become circumferencial direction to arrange.Hemispherical groove in the utility model in disc plays the effect of buffering sinuous flow, first time buffering is formed when petroleum liquid impacts hemispherical groove, it is second time buffering when arriving arc groove, vortex-like sinuous flow can be formed, thus reduce oil to the impact of flashboard, have and preferably stop and cushioning effect.
Description
Technical field
The utility model relates to a kind of pipeline assistant tool, particularly relates to a kind of pipeline pressure-resisting plate.
Background technique
Pipeline transport is with the mode of movement of pipeline as a kind of long distance delivery liquids and gases goods and materials of means of transportation, being a kind of special in the means of transportation of grown place to market transfer oil, coal and chemical products, is the special constituent element of line haul in consolidated delivery net.When utilizing pipeline to carry out petroleum transportation, some high pressure pipe line needs use various valve to obtain the functions such as cut-off, discharge to reach different objects, but the valve at some position only plays the object stopping oil flow, just can use the structures such as flashboard comparatively simple and with low cost, pressure-resisting plate in this case.There is the position stopped and easily occur deviation in traditional flashboard, blocking effect is poor; Meanwhile, because speed and strength during oil flow is comparatively large, impact when comparatively smooth gate panel surface, flashboard can bear larger oil pressure, causes security incident sometimes.
Model utility content
The utility model provides a kind of petroleum pipeline pressure-resisting plate.
The technical solution of the utility model is: a kind of pipeline pressure-resisting plate, comprise disc, described disc center is a hemispherical groove, two circular arc draw-in grooves are offered in disc upper edge, described hemispherical groove upper surface sets gradually three layers of buffer strip by edge to center portion, each buffer strip comprises four and half arc grooves respectively, and described four and half arc grooves become circumferencial direction to arrange.
Preferably, described circular arc draw-in groove is oppositely arranged.
Preferably, four and half arc grooves in described third layer buffer strip and half arc groove interval of all the other two-layer buffer strips are arranged.
The beneficial effects of the utility model: the hemispherical groove in the utility model in disc plays the effect of buffering sinuous flow, first time buffering is formed when petroleum liquid impacts hemispherical groove, it is second time buffering when arriving arc groove, vortex-like sinuous flow can be formed, thus reduce oil to the impact of pressure-resisting plate, have and preferably stop and cushioning effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the side view of Fig. 1;
In figure: 1 disc, 2 hemispherical grooves, 3 circular arc draw-in grooves, 4 half arc grooves, 5 third layer buffer strips.
Embodiment
By reference to the accompanying drawings the mode of execution that the utility model provides is described in further detail:
As shown in Figure 1, 2, a kind of pipeline pressure-resisting plate, comprise disc 1, described disc 1 center is a hemispherical groove 2, two circular arc draw-in grooves 3 are offered in disc 1 upper edge, described hemispherical groove 2 upper surface sets gradually three layers of buffer strip by edge to center portion, and each buffer strip comprises four and half arc grooves 4 respectively, the 4 one-tenth circumferencial direction arrangements of described four and half arc groove.
In the present embodiment preferably, described circular arc draw-in groove 3 is oppositely arranged.
In the present embodiment preferably, half arc groove 4 interval of four and half arc grooves 4 in described third layer buffer strip 5 and all the other two-layer buffer strips is arranged.
In this description, the utility model is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
