Abstract

The invention provides a flap valve and relates to hydraulic equipment. The flap valve mainly comprises a valve body, a valve cover and a hinge. A valve body seal face is processed into a groove type, and water stopping seal bars are embedded in the valve body seal face. The back end of the valve cover is provided with reinforced ribs which are arranged crosswise and lengthways. The front end of the valve cover is provided with a reinforced plate which is in an end-socket arc shape. A cavity is formed between the reinforced plate and the valve cover. A rib plate support reinforced plate is arranged in the cavity. Holes which are connected with the inner portion of the cavity are formed in the bottom portion of the reinforced plate. The reinforced rib of the flap valve increases bearing degree of the valve cover and is high in strength. When pressed by water, the front end of the valve cover flows water backwards into the cavity, water in the cavity flows outwards automatically, and self-cavity of the valve cover is reduced. The flap valve is in favor of water draining, reliable in work, free from manual operation, simple in structure and reasonable in design.

Description

A kind of flap valve

Technical field:

The present invention relates to the environment-protective water construction equipment, be specifically related to a kind of flap valve.

Background technique:

Flap valve is applicable to the various pipelines in various plumbing and sewage treatment project, the outlet pipe of water pump, and going out flow in pumping plant does overflow, non-return effect in well and water channel, also can be used for various vertical shaft well lids.In the larger place of some impact forces, flap valve is according to the self gravitation sealing, and flap valve sealing efficient is bad, and even some flap valve can't stand the high strength pressure-bearing, and intensity is not high.

Summary of the invention:

Technical problem to be solved by this invention is to overcome the defective of prior art, provides stagnant water effect good, and backflow phenomenon is few, intensity high a kind of flap valve.

Technical problem to be solved by this invention realizes by the following technical solutions.

A kind of flap valve, mainly comprise a body, door closure and hinge, it is characterized in that: described door body sealing surface is processed into grooved, embedded waterstop sealing bar, described door closure rear end is provided with stiffening rib, the door closure front end is provided with stiffening plate, forms a cavity between stiffening plate and door closure, and the stiffening plate bottom is provided with the hole and connects in cavity.

The horizontal longitudinal arrangement of described stiffening rib increases door closure rear end intensity.

Described stiffening plate is end socket shape arch, and intensity is high, appearance looks elegant.

Establish floor support reinforcing plate in described cavity, strengthen the pressure-bearing degree of stiffening plate.

The present invention is simple in structure, and is reasonable in design, and stiffening rib has increased the pressure-bearing degree of door closure, intensity is high, and the door closure front end has increased the weight of door closure self because hydraulic pressure can pour in down a chimney water in cavity, stagnant water effect is better, pours in down a chimney the water yield in the cavity hydraulic pressure before according to door closure and determines, in door closure, hydraulic pressure is large during with the front hydraulic pressure of door closure, in door closure, water has rushed door closure, in cavity, water flows out automatically, and the door closure self gravitation reduces, and more is conducive to draining, reliable operation does not need manual operation.

Description of drawings:

Fig. 1 is structural representation of the present invention;

Embodiment:

For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.

A kind of flap valve as shown in Figure 1, mainly comprise a body 1, door closure 2 and hinge 3, described door body 1 sealing surface is processed into grooved, embedded waterstop sealing bar 4, and described door closure 2 rear ends are provided with stiffening rib 5, the horizontal longitudinal arrangement of stiffening rib 5, door closure 2 front ends are provided with stiffening plate 6, and stiffening plate 6 is end socket shape arch, and 2 of stiffening plate 6 and door closures form a cavity 7, establish floor 8 support reinforcing plates 6 in cavity 7, stiffening plate 6 bottoms are provided with hole 9 and connect in cavitys 7.

Above demonstration and described basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
