Abstract
The invention relates to a novel flap valve. The racket door comprises a racket door seat and a door body, wherein a hinged support is arranged above the racket door seat, an ear plate is arranged at the upper end of the door body and connected with the hinged support through a hinged shaft, a sleeve is sleeved outside the racket door seat, a sealing gasket is arranged between the sleeve and the outer wall of the racket door seat, and the outer end of the sealing gasket is in contact with the periphery of the inner end face of the door body. The flap valve is simple in structure, convenient and quick to install and convenient to maintain, the flap valve can be effectively sealed by placing the sealing gasket between the flap valve seat and the sleeve, the sealing gasket is not easy to fall off, and the service life is long.
Description
Technical Field
The invention relates to a flap valve, in particular to a novel flap valve.
Background
Flap valve installed mainly at the end of drainage pipeline to prevent the reverse flow of external water. The material is divided into various materials such as stainless steel, cast iron, section steel, composite material (glass fiber reinforced plastics) and the like. The flap valve is divided into a plurality of types, such as a floating box type flap valve, a flat flap valve, a sleeve type flap valve and the like, and is a one-way valve arranged at the outlet of a drainage pipe at the edge of a river, when the river tide level is higher than the opening of a water outlet pipe and the pressure is higher than the pressure in the pipe, a flap valve panel automatically closes to prevent the river tide water from flowing back into the drainage pipe. The sealing gasket of the prior flap valve is basically arranged on the inner end surface of the door body and is easy to fall off from the door body after long-time use, so that the sealing effect is poor.
Disclosure of Invention
In view of the above defects, the invention aims to provide a novel flap valve which has a simple structure, is convenient and quick to install and maintain, has a sealing gasket which is not easy to fall off, and has a good sealing effect.
Therefore, the technical scheme adopted by the invention is as follows:
the racket door comprises a racket door seat and a door body, wherein a hinged support is arranged above the racket door seat, an ear plate is arranged at the upper end of the door body and connected with the hinged support through a hinged shaft, a sleeve is sleeved outside the racket door seat, a sealing gasket is arranged between the sleeve and the outer wall of the racket door seat, and the outer end of the sealing gasket is in contact with the periphery of the inner end face of the door body.
As a further improvement of the technical scheme, the flapper seat is connected with the sleeve through a bolt, and the bolt penetrates through the sealing gasket.
As a further improvement of the technical scheme, the upper end of the sealing gasket is higher than the outer ends of the flap valve seat and the sleeve.
As a further improvement of the technical scheme, the interior of the door body is a cavity, and a filling opening is formed in the side wall of the exterior of the door body.
As a further improvement of the technical scheme, the number of the hinged supports is 2.
The invention has the advantages that:
the flap valve is simple in structure, convenient and quick to install and convenient to maintain, the flap valve can be effectively sealed by placing the sealing gasket between the flap valve seat and the sleeve, the sealing gasket is not easy to fall off, and the service life is long.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure, 1 is a flap seat, 2 is a door body, 3 is a hinged support, 4 is an ear plate, 5 is a hinged shaft, 6 is a sleeve, 7 is a sealing gasket, 8 is a bolt, and 9 is a filling port.
Detailed Description
The utility model provides a novel flap valve, is including clapping a seat 1 and a body 2, clap 1 top of a seat and be equipped with hinged-support 3, 2 upper ends of the body are equipped with otic placode 4, otic placode 4 passes through articulated shaft 5 with hinged-support 3 and is connected, clap 1 overcoat of a seat and have sleeve 6, be equipped with sealed the pad 7 between sleeve 6 and the 1 outer wall of a seat of clapping, the outer end of sealed pad 7 contacts all around with the terminal surface in the body 2.
As a further improvement of the technical scheme, the flapper seat 1 is connected with the sleeve 6 through a bolt 8, and the bolt 8 penetrates through the sealing gasket 7.
As a further improvement of the technical scheme, the upper end of the sealing gasket 7 is higher than the outer ends of the flap valve seat 1 and the sleeve 6.
As a further improvement of the technical scheme, the interior of the door body 2 is a cavity, and a filling opening 9 is arranged on the side wall of the exterior of the door body 2.
As a further improvement of the technical scheme, the number of the hinged supports is 2.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
