SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a weight flap valve to solve the tar or the dust adhesion that exist among the prior art and harden in sealed face junction and the sealed not tight, the problem of leaking out, vacuum that causes.

In order to solve the technical problem, the utility model discloses a technical scheme be: the heavy hammer flap valve comprises a shell with an upper opening and a lower opening, wherein a downward sealing cone hopper is arranged at the upper opening in the shell, two opposite side walls of the shell are respectively provided with a bearing with a seat at the outer side of the opening part of the sealing cone hopper, a turnover shaft is arranged between the bearings with the seats, a sealing turnover plate capable of completely covering the opening part of the sealing cone hopper is arranged on the turnover shaft, a turnover plate swing arm is fixedly arranged between the bearings with the seats, a balancing weight is sleeved on the turnover plate swing arm, a cutter body is arranged at the free end of the sealing turnover plate, the section of the cutter body is trapezoidal, the upper edge of the trapezoid is extremely narrow, a sharp sealing surface is formed, and the sealing surface faces to the inlet of a valve body; a groove is formed at the inlet of the valve body of the cone sealing hopper; when the sealing flap is closed, the knife body can be embedded into the groove.

The size of the groove is correspondingly arranged according to the size of the cutter body.

Wherein the cutter body adopts a high-temperature-resistant and wear-resistant casting SCH₂And (4) preparing.

And the balancing weight is provided with a locking bolt for fixing the position of the balancing weight.

The utility model has the advantages that: be different from prior art's condition, the utility model provides a pair of weight flap valve structure sets up the cutter body through turning over on the board at sealed to and correspond at sealed awl fill and set up the recess, under the condition that has material such as tar and dust to bond at the valve body import department that sealed awl was fought, the cutter body that should seal the board of turning over can shovel into wherein, closely laminates with the recess that sealed awl was fought under the action of gravity of configuration piece, constitutes effectively sealed. Therefore, the problems of not tight sealing, air leakage and vacuum caused by hardened objects at the joint of the sealing surfaces in the prior art are solved.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described in more detail with reference to the accompanying drawings and embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Fig. 1 is a schematic structural view of a heavy hammer flap valve according to an embodiment of the present invention. The heavy hammer flap valve 10 comprises a machine shell 11, a sealing cone hopper 12, a bearing 13 with a seat, a turnover shaft 14, a sealing flap 15, a flap swing arm 16 and a balancing weight 17.

Specifically, the heavy hammer flap valve 10 is provided with a casing 11 with an upper opening and a lower opening, and a downward sealing conical hopper 12 is arranged at the upper opening inside the casing 11. The bottom of the sealing cone 12 is open and the mouth is in the same plane. Two opposite side walls of the casing 11 are respectively provided with a bearing 13 with a seat outside the opening part of the conical hopper 12, the overturning shaft 14 is arranged between the two bearings 13 with the seat, and the overturning shaft 14 is provided with a sealing turnover plate 15 which can completely cover the opening part of the conical hopper 12.
