Abstract
The utility model provides a flap check valve, and relates to a check valve. The flap check valve comprises a valve body, a valve flap and a valve cover arranged at the top of the valve body. The flap check valve is characterized in that a magnet is arranged at a movable end of the valve flap, the N-pole of the magnet corresponds to the valve body, and the S-pole of the magnet corresponds to the valve cover; a magnet is arranged on a portion, contacting the movable end of the valve flap, of the valve body, and the S-pole of the magnet corresponds to the valve flap; a magnet is arranged on the valve cover, the S-pole of the magnet is outwards, and the valve flap is composed of rubber and a steel plate. The flap check valve is simple in structure and reasonable in design, the magnetism principle is used, the N-pole of the magnet on the valve cover repels the N-pole of the magnet on the valve flap, the N-pole of the magnet on the valve flap attracts the S-pole of the magnet on the valve body, and back-and-forth range of the valve flap can be reduced, sealing performance can be improved, and noise is reduced at the same time.
Description
Technical field:
The utility model relates to a kind of safety check, relates in particular to a kind of flap valve.
Background technique:
Safety check claims again one-way valve or check valve, is mainly used in the pipeline mounted pump outlet port of the industrial departments such as supply and drain water system, petrochemical industry, prevents that medium from flowing backwards, and can also be installed in wet pit and import and export on the bypass tube of water pipe, prevents that the pond aqueous reflux from destroying pump.The own wt that existing flap valve is depended merely on flap is covered on valve body, and sealing is inadequate, and it is large to open or close amplitude, and noise is large, easily causes damage.
The model utility content:
Technical problem to be solved in the utility model is to overcome the defective of prior art, and a kind of resistance to erosion is provided, good airproof performance, a kind of flap valve that noise is little.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of flap valve, comprise valve body, flap and be located at the valve gap at valve body top, it is characterized in that: described flap movable end is provided with magnet, the N pole pair of magnet is answered valve body, the S pole pair is answered valve gap, and the place, contact position of described valve body and flap movable end is provided with magnet, and the S pole pair of magnet is answered flap, described valve gap is provided with magnet, and the S magnetic pole of magnet outwardly.
Described flap is comprised of rubber and steel plate, resistance to erosion.
Described rubber adopts the fine oil resistant rubber of fourth.
Compacting forms described steel plate through high temperature.
The utility model is simple in structure, and is reasonable in design, utilizes magnetic principles, the N magnetic pole that valve gap is provided with on N magnetic pole and the flap repels mutually, and the N magnetic pole on the flap and valve body are provided with the S magnetic pole and attract each other, can make flap back and forth amplitude reduce, increase sealing, also reduced noise simultaneously.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of flap valve as shown in Figure 1, comprise valve body 1, flap 2 and be located at the valve gap 3 at valve body top, wherein flap 2 movable ends are provided with magnet 4, the N pole pair of magnet 4 is answered valve body 1, the S pole pair is answered valve gap 3, wherein valve body 1 is provided with magnet 5 with the place, contact position of flap 2 movable ends, the S pole pair of magnet 5 is answered flap 2, wherein valve gap 3 is provided with magnet 6, the S magnetic pole of magnet 6 outwardly, wherein flap 2 is comprised of rubber 7 and steel plate 8, and wherein rubber 7 adopts the fine oil resistant rubber of fourth, and compacting forms its light plate 8 through high temperature.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
