Abstract
The utility model discloses a kind of petroleum pipeline pressure-resisting plate, comprise disc, described disc center is a hemispherical groove, a trapezoidal draw-in groove is offered in disc upper edge, described hemispherical groove upper surface is set gradually two-layer buffer strip to center portion by edge, each buffer strip comprises respectively four arc grooves, and described four arc grooves become circumferencial direction to arrange.Hemispherical groove in the utility model in disc plays the effect of buffering sinuous flow, in the time that impacting hemispherical groove, petroleum liquid forms buffering for the first time, arrive when arc groove as cushioning for the second time, can form vortex-like sinuous flow, thereby reduce the impact of oil to flashboard, have and preferably stop and cushioning effect.
Description
Technical field
The utility model relates to a kind of pipeline assistant tool, relates in particular to a kind of petroleum pipeline pressure-resisting plate.
Background technique
Pipeline transport is a kind of mode of movement of growing distance conveying liquids and gases goods and materials as means of transportation with pipeline, being a kind of means of transportation to market transfer oil, coal and chemical products by grown place specially, is the special constituent element of main line transport in unified transport network.In the time utilizing pipeline to carry out oil transport, on some high pressure pipe line, need to obtain with various valves the functions such as cut-off, discharge to reach different objects, but the valve at some position only plays the object that stops oil flow, just can use in this case the structure such as flashboard, pressure-resisting plate comparatively simple and with low cost.Traditional flashboard exists the position stopping easily to occur deviation, and blocking effect is poor; Meanwhile, the speed and strength during due to oil flow is larger, impacts in the time of comparatively smooth flashboard surface, and flashboard can bear larger oil pressure, causes sometimes security incident.
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 petroleum pipeline pressure-resisting plate, comprise disc, described disc center is a hemispherical groove, a trapezoidal draw-in groove is offered in disc upper edge, described hemispherical groove upper surface is set gradually two-layer buffer strip to center portion by edge, each buffer strip comprises respectively four arc grooves, and described four arc grooves become circumferencial direction to arrange.
Preferably, the width of described trapezoidal draw-in groove is diminished in groove gradually by opening.
The beneficial effects of the utility model: the hemispherical groove in the utility model in disc plays the effect of buffering sinuous flow, in the time that impacting hemispherical groove, petroleum liquid forms buffering for the first time, arrive when arc groove as cushioning for the second time, can form vortex-like sinuous flow, thereby reduce the impact of oil to flashboard, have and preferably stop and cushioning effect.
Brief description of the drawings
Fig. 1 is a kind of embodiment's of the utility model structural representation;
Fig. 2 is the side view of Fig. 1;
In figure: 1 disc, 2 hemispherical grooves, 3 trapezoidal draw-in grooves, 4 arc grooves.
Embodiment
The mode of execution by reference to the accompanying drawings the utility model being provided is described in further detail:
As shown in Figure 1, 2, a kind of petroleum pipeline pressure-resisting plate, comprise disc 1, described disc 1 center is a hemispherical groove 2, and a trapezoidal draw-in groove 3, described trapezoidal card are offered in disc 1 upper edge, 3 width is diminished in groove gradually by opening, described hemispherical groove 2 upper surfaces are set gradually two-layer buffer strip to center portion by edge, each buffer strip comprises respectively four arc grooves 4, and 4 one-tenth circumferencial directions of described four arc grooves are arranged.
In this specification, the utility model is described with reference to its specific embodiment.But, still can make various amendments 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.
