Abstract
The invention relates to a check piece. The check piece is characterized in that a main body is a rubber plate made of soft rubber materials; the rubber plate is round; the center of the rubber plate is provided with a round installing hole; the rubber plate is internally provided with six to eight reinforcing metal strips which are distributed in a radial shape; the reinforcing metal strips are uniformly distributed around the center of the rubber plate. The check piece is simple in structure, convenient to manufacture and low in production cost.
Description
Technical field
The present invention relates to a kind of non-return sheet.
Background technique
Safety check is one of valve conventional in pipework, for preventing the refluence of pipeline internal medium in pipework, safety check is a kind of automatic valve that relies on pressure medium opening and closing, for only allowing medium to a pipeline that direction is mobile, the core of safety check is the non-return sheet of safety check, and non-return sheet is generally rubber material and makes, in the market the non-return sheet general structure of common safety check more complicated all, also more complicated is installed, and cost of production is also comparatively expensive.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of non-return sheet simple in structure.
The present invention is achieved by the following technical solutions, a kind of non-return sheet, its main body is the rubber plate that a soft rubber material is made, described rubber plate is rounded, the center of described rubber plate has circular mounting hole, rubber plate inside is provided with 6-8 the reinforcement metal bar radially distributing, and described reinforcement metal bar is uniformly distributed around the center of rubber plate.
Further, the thickness of described rubber plate is 3mm.
Further, described reinforcement metal bar is 8, and described reinforcement metal bar is made by light-weight high-strength material.
The advantage of a kind of non-return sheet provided by the invention is: compared with prior art, the present invention is simple in structure, easily manufactured, and cost of production is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
In order to make object of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is structural representation of the present invention.
As shown in FIG., a kind of non-return sheet of the present invention, its main body is the rubber plate 1 that a soft rubber material is made, described rubber plate 1 is rounded, the thickness of rubber plate 1 is 3mm, and the center of described rubber plate 1 has circular mounting hole 3, and rubber plate 1 inside is provided with 8 reinforcement metal bars 2 that radially distribute, described reinforcement metal bar 2 is made by light-weight high-strength material, and described reinforcement metal bar 2 is uniformly distributed around the center of rubber plate.
In use, this non-return sheet is arranged on safety check by mounting hole, the support aperture plate arranging in the liquid entering hole of non-return sheet and valve seat fits, during normal operation, and the pressure flow body jack-up non-return sheet being flowed into by liquid entering hole, make fluid can pass through smoothly safety check, when reverse fluid flow, under the effect of pressure, make non-return sheet tightly be attached to propping bar online, stop passing through of fluid, played non-return effect.
In sum, the advantage of a kind of non-return sheet provided by the invention is: compared with prior art, the present invention is simple in structure, easily manufactured, and cost of production is low.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
