Description

F-shaped flap valve

Technical Field

The utility model relates to a manger plate gate especially relates to the improvement to manger plate gate seal structure.

Background

At present, the flap valve is generally used for river course manger plate dam, and the river bottom is submerged in at ordinary times in the unnecessary time, then utilizes power to make the valve plate of flap valve rise when needing to use, and the perpendicular to river course is used for the manger plate, adopts between valve plate and the river course lateral wall to utilize the vulcanization to fix the rubber seal on the valve plate to seal simultaneously, prevents to leak, but because the adhesive tape need be long-term with the river bank friction, consequently appear the damaged needs often to be changed easily. The other sealing mode for the air shield dam is that an inflatable rubber bag is arranged on a river bank, and the rubber bag is inflated after a valve plate is lifted in place, so that the sealing effect can be achieved, the rubber bag is not inflated when the valve plate rotates, the contact time between the rubber bag and the valve plate can be shortened, the service life is prolonged, but only one layer of sealing structure can be formed, namely, the inflated rubber bag is directly contacted with the valve plate to form linear sealing, and the sealing effect is poor when the water pressure is too high.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a F-shaped flap valve which forms a plurality of seals and has good sealing effect with the river bank when retaining water.

The utility model discloses a following technical scheme realizes: f type flap valve, including the valve plate, the part of valve plate and bank contact is equipped with sealing device, sealing device is including locating first sealed gasbag on the valve plate with locate at least one second sealed gasbag on the bank, fixed a plurality of sealed sand grips on the first sealed gasbag, be equipped with a plurality of seal grooves on the second sealed gasbag, work as when the valve plate rises sealed sand grip block is in the seal groove.

The river bank is provided with at least one mounting groove, each second sealing air bag is arranged in the mounting groove, the bottom of the mounting groove is provided with a pipeline communicated with an air compressor, and the pipeline is used for inflating the second sealing air bags after the valve plate rises.

The valve plate is internally provided with an inflation tube which is communicated with an air compressor, and the inflation tube is used for inflating the first sealing air bag after the valve plate rises.

Compared with the prior art, the utility model discloses the valve plate rises promptly the valve plate is perpendicular with the river course, be used for blocking water, the valve plate rises to aerify for first air-tight bag after target in place, aerify for the sealed gasbag of second after the first air-tight bag is aerifyd and is accomplished, thus, sealed sand grip just blocks in the seal groove, the pressurization through first air-tight bag and the sealed gasbag of second ensures sealed effect, then first air-tight bag and the sealed gasbag gassing of second when the valve plate resets needs, sealed sand grip and seal groove separation, put down the valve plate again and reset, can reduce the friction between the sealing member like this, the life of extension sealed sand grip. And more than one sealing convex strip is arranged on the first sealing air bag, so that a plurality of seals can be formed, and the sealing effect is good.

FIG. 2 is a schematic view of the sealing device;

in the figure: 1. river banks; 2. a valve plate; 3. a sealing device; 31. a first sealed bladder; 32. a second sealed airbag; 33. sealing the convex strips; 34. a sealing groove; 35. and (4) mounting the groove.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2, the F-type flap valve includes a valve plate 2, a sealing device 3 is disposed at a contact portion of the valve plate 2 and a river bank 1, the sealing device 3 includes a first sealing air bag 31 disposed on the valve plate 2 and at least one second sealing air bag 32 disposed on the river bank 1, a plurality of sealing protruding strips 33 are fixed on the first sealing air bag 31, a plurality of sealing grooves 34 are disposed on the second sealing air bag 32, and when the valve plate 2 is lifted, the sealing protruding strips 33 are engaged in the sealing grooves 34. The valve plate 2 rises and is the valve plate 2 perpendicular with the river course for block water, the valve plate 2 rises to aerify first sealed gasbag 31 after target in place, aerify second sealed gasbag 32 after the completion of aerifing of first sealed gasbag 31, like this, sealed sand grip 33 just blocks in seal groove 34, guarantee sealed effect through the pressurization of first sealed gasbag 31 and second sealed gasbag 32, then first sealed gasbag 31 and second sealed gasbag 32 deflate when needing to reset valve plate 2, sealed sand grip 33 and seal groove 34 separate, put down valve plate 2 again and reset, can reduce the friction between the sealing member like this, the life of extension sealed sand grip 33. And more than one sealing convex strip 33 is arranged on the first sealing air bag 31, so that a plurality of seals can be formed, and the sealing effect is good.
