Abstract
The invention discloses a concave gate plate for petroleum transportation pipelines. The concave gate plate comprises a disc body, a trapezoidal clamping groove is formed at the upper edge of the disc body, a bearing surface is arranged on each of the front side and the back side of the disc body respectively, and three mutually connected fan-shaped buffering grooves with fan-shaped cross sections are formed on each bearing surface; a protrusion is formed at the bottom of each sector buffering groove, every three protrusions are spliced to form a cone frustum, and the top of each cone frustum is fixedly connected via a center positioning component. The concave gate plate has the advantages that a plurality of buffering recessed areas in fan-shaped structures are arranged at the center of each bearing surface of the disc body and matched with central conical positioning blocks, so that blocking and buffering effects are good; when liquid petroleum impacts buffering recesses, vortex turbulence is formed, and accordingly impact of the petroleum on the gate plate is reduced; the profile is matched with the cross section of a petroleum pipeline, and sealing performance of the concave gate plate is further improved.
Description
Technical field
The present invention relates to a kind of petroleum pipeline pipe fitting, relate in particular to a kind of oil delivering pipe concave flashboard.
Background technique
Pipeline transport is with a kind of defeated mode of growing distance conveying liquids and gases goods and materials of pipeline as 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 main line transportation in the unified transport network.When utilizing pipeline to carry out the oil transportation, some high pressure pipe lines need with various valves obtain to end, the function such as discharging to be to reach different purposes, but the valve at some position only plays the purpose that stops oil flow and gets final product, and just can use the structures such as flashboard comparatively simple and with low cost, pressure-resisting plate in this case.Traditional flashboard exists much and does not go, and for example: the cross section is generally square or rectangular, and flashboard can't well cooperate with the section of petroleum pipeline, and deviation easily appears in the position that therefore stops, blocking effect is relatively poor; Simultaneously, the speed and strength during owing to oil flow is larger, impacts when comparatively smooth flashboard surface, and flashboard can bear larger oil pressure, causes sometimes security incident.Therefore, for above aspect, need to make rational improvement.
Summary of the invention
The purpose of this invention is to provide a kind of better, the long-lived oil delivering pipe of intensity, anti-pressure ability concave flashboard that has the inner groovy structure, can strengthen pipeline and plate junction point, to solve many deficiencies of prior art.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of oil delivering pipe concave flashboard, comprise disc, a trapezoidal draw-in groove is offered in described disc upper edge, and described disc is positive, the back side is respectively arranged with a supporting plane, is positioned at that three cross sections that join are set on each supporting plane is fan-shaped fan-shaped buffer groove; Simultaneously, be positioned at each fan-shaped buffer groove bottom a projection is set, these three projection splicings form a circular cone, and described circular cone top is fixedly connected with by the centralized positioning assembly.
Correspondingly, the width of described trapezoidal draw-in groove is diminished in groove gradually by opening, and described supporting plane periphery arranges a circle rubber sealing boot.
The beneficial effect of oil delivering pipe concave flashboard of the present invention is: the buffering sunk area of some sector structures is set and cooperates the tapered centre positioning block by the center at the disc supporting plane, have better stopping and cushioning effect, when petroleum liquid impacts the buffering recess, can form vortex-like sinuous flow, thereby reduce oil to the impact of flashboard, this profile and petroleum pipeline section match, further improved the sealability of product, be conducive in the oil carrier, apply.
Description of drawings
The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.
Fig. 1 is the structural drawing of the described oil delivering pipe of embodiment of the invention concave flashboard.
Among the figure: 1, disc; 2, trapezoidal draw-in groove; 3, supporting plane; 4, fan-shaped buffer groove; 5, rubber sealing boot; 6, circular cone; 7, centralized positioning assembly.
Embodiment
As shown in Figure 1, the described oil delivering pipe of embodiment of the invention concave flashboard, comprise disc 1, the width ecto-entad that a trapezoidal draw-in groove 2 and this trapezoidal draw-in groove 2 are offered in described disc 1 upper edge diminishes gradually, and described disc 1 front, the back side are respectively arranged with a supporting plane 3 and are positioned at that three cross sections that join are set on each supporting plane 3 is fan-shaped fan-shaped buffer groove 4; Simultaneously, described supporting plane 3 peripheries arrange a circle rubber sealing boot 5, be positioned at each fan-shaped buffer groove 4 bottom a projection is set, and these three projection splicings form a circular cone 6, and described circular cone 6 tops are fixedly connected with by centralized positioning assembly 7.
Claims (3)
1. an oil delivering pipe concave flashboard comprises disc, it is characterized in that:
A trapezoidal draw-in groove is offered in described disc upper edge, and described disc is positive, the back side is respectively arranged with a supporting plane, is positioned at that three cross sections that join are set on each supporting plane is fan-shaped fan-shaped buffer groove;
Simultaneously, be positioned at each fan-shaped buffer groove bottom a projection is set, these three projection splicings form a circular cone, and described circular cone top is fixedly connected with by the centralized positioning assembly.
2. a kind of oil delivering pipe concave flashboard as claimed in claim 1, it is characterized in that: the width of described trapezoidal draw-in groove is diminished in groove gradually by opening.
