Abstract

The utility model discloses a pipeline sealing plate. The pipeline sealing plate comprises a disc body, wherein a trapezoid clamping groove is formed in the upper edge of the disc body, the front surface and the back surface of the disc body are respectively provided with a bearing surface, and two semi-circular buffering concave areas are formed in the center of each bearing surface. Meanwhile, a horizontal baffle is installed between the two semi-circular buffering concave areas, the two sides of the horizontal baffle are respectively connected with the edges of the disc body, a sealing strip is arranged in the connecting position of every two edges, and a rotary handle is arranged on the outer surface of the horizontal baffle. The pipeline sealing plate has the advantages that the buffering concave areas are arranged in the centers of the bearing surfaces of the disc body and matched with the horizontal baffle, a good blocking and buffering effect is achieved, an eddy turbulent flow is generated when liquid petroleum impacts the buffering concave areas so that impact to a flashboard by the petroleum can be lowered, the profile is matched with a section of a petroleum pipeline, and the sealing performance of products is further improved.

Description

A kind of seal for pipe joints plate

Technical field

The utility model relates to a kind of petroleum pipeline pipe fitting, relates in particular to a kind of seal for pipe joints plate.

Background technique

Pipeline transport is a kind of defeated mode 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 transportation in unified transport network.When utilizing pipeline to carry out the oil transportation, need to obtain with various valves the functions such as cut-off, discharge to reach different purposes on some high pressure pipe line, but the valve at some position only plays the purpose that stops oil flow and gets final product, 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: cross section is generally square or rectangular, and flashboard can't well coordinate with the section of petroleum pipeline, and deviation easily appears in the position therefore stopped, blocking effect is poor; Simultaneously, the speed and strength during due 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.

The model utility content

The purpose of this utility model is to provide a kind of better, long-lived seal for pipe joints plate of intensity, anti-pressure ability that has the double compression resistant structure, can strengthen pipeline and plate junction point, to solve many deficiencies of prior art.

The purpose of this utility model is carried out specific implementation by the following technical programs:

A kind of seal for pipe joints plate, comprise disc, and 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 and be positioned at each supporting plane center position arranges two semicircle buffering sunk areas; Simultaneously, between two semicircle buffering sunk areas, a horizontal baffle of installation and this horizontal baffle both sides join with the disc edge respectively, be positioned at connecting part, two edges a Stamping Steel Ribbon respectively is set, described horizontal baffle outer surface is provided with rotatable handle.

Correspondingly, described horizontal baffle length equals the diameter of section length of disc, and described supporting plane periphery arranges a circle rubber sealing boot.

The beneficial effect of seal for pipe joints plate described in the utility model is: by the center at the disc supporting plane, the buffering sunk area is set and coordinates horizontal baffle, have and preferably stop and cushioning effect, when petroleum liquid impacts the buffering recess, can form vortex-like sinuous flow, thereby reduce the impact of oil to flashboard, this profile and petroleum pipeline section match, and have further improved the sealability of product, are conducive to apply in the oil carrier.

The accompanying drawing explanation

Below according to drawings and embodiments the utility model is described in further detail.

Fig. 1 is the structural drawing of the described seal for pipe joints plate of the utility model embodiment.

In figure: 1, disc; 2, trapezoidal draw-in groove; 3, supporting plane; 4, semicircle buffering sunk area; 5, rubber sealing boot; 6, horizontal baffle; 7, Stamping Steel Ribbon; 8, rotatable handle.

Embodiment

As shown in Figure 1, the described seal for pipe joints plate of the utility model embodiment, 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 each supporting plane 3 center position two semicircle buffering sunk areas 4 is set; Simultaneously, described supporting plane 3 peripheries arrange a circle rubber sealing boot 5, between two semicircle buffering sunk areas 4, a horizontal baffle 6 of installation and this horizontal baffle 6 both sides join with disc 1 edge respectively, be positioned at connecting part, two edges a Stamping Steel Ribbon 7 respectively is set, described horizontal baffle 6 outer surfaces are provided with rotatable handle 8, and horizontal baffle 6 length wherein equal the diameter of section length of disc 1.
