Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows: as shown in fig. 1-3, a filtering overflow valve device comprises a valve body 1, a connecting pipe 2, a sealing pipe 3, a pressure relief spring 5 and a sealing ball 6, wherein the valve body 1 is hollow cylindrical, the connecting pipe 2 is fixedly arranged at the rear end of the valve body 1, the sealing pipe 3 is cylindrical, the sealing pipe 3 is movably connected with the rear end of the connecting pipe 2, the pressure relief spring 5 is arranged inside the valve body 1, the sealing ball 6 is spherical, the sealing ball 6 is arranged on the pressure relief spring 5, through holes 4 communicated with the inside of the valve body 1 are arranged around the side wall of the valve body 1, the through holes 4 are circular holes, a sealing block 7 is fixedly arranged inside the sealing pipe 3, the sealing block 7 is hollow cylindrical, a sealing plate 8 is embedded on the rear side wall of the sealing block 7, the sealing plate 8 is a circular plate, a telescopic rod 9 fixedly connected with the sealing plate 8 is arranged inside the telescopic rod 9, telescopic link 9 is cylindrical structure, has cup jointed on telescopic link 9 with closing plate 8 fixed connection's sealing spring 10, set up on the preceding lateral wall face of sealed piece 7 with the inside pressure release hole 11 that communicates of sealed piece 7, pressure release hole 11 is the circular shape hole, the internally mounted of connecting pipe 2 has erection column 12, erection column 12 is cylindrical structure, the position fixed mounting that the lateral wall of erection column 12 corresponds pressure release hole 11 has push rod 13, push rod 13 is cylindrical structure.

When the pressure relief valve is used, the rear end of the sealing tube 3 is connected with a pressure container, after the valve body 1 is installed on the sealing tube 3 through the connecting tube 2, the push rod 13 installed on the installation column 12 penetrates through the pressure relief hole 11 to push the sealing plate 8 backwards, the sealing plate 8 drives the sealing plate 8 to move backwards, so that the sealing plate 8 is separated from the sealing block 7, high-pressure gas of the pressure container can penetrate through the sealing block 7 to enter the inside of the connecting tube 2 after the sealing plate 8 is separated from the sealing block 7, when the pressure in the pressure container is overhigh, the gas can penetrate through the sealing block 7 to enter the sealing tube 2, the gas can push the sealing ball 6 at the top of the front side, the sealing ball 6 can push the pressure relief spring 5 towards the front side after being pushed, so that the gas can leave the inside of the valve body 1 through the through hole 4 to achieve the pressure relief effect, when the valve body 1 and the connecting tube 2 are required to be detached for cleaning, the connecting tube 2 is only required to be taken down from the sealing tube 3, push rod 13 also can leave the inside of sealed piece 7, and the closing plate 8 has lost can be because the elasticity of telescopic link 9 is pulled back sealed piece 7 after the power of being pushed up, and gaseous just can't get into the inside of connecting pipe 2 through sealed piece 7 when closing plate 8 gets back to on sealed piece 7, has reached the condition emergence that can not appear revealing again when making things convenient for the washing.

Example two: on the basis of the first embodiment, as shown in fig. 4, a rubber pad 14 is embedded in the front side of the inside of the connecting pipe 2, the rubber pad 14 is of a circular ring structure made of rubber, a push plate 15 matched with the inside of the connecting pipe 2 is fixedly installed at the rear end of the sealing ball 6, and the push plate 15 is a circular plate.

When using, when the contact of ball sealer 6 and connecting pipe 2 makes between valve body 1 and the connecting pipe 2 sealed, because install rubber pad 14 on the connecting pipe 2, and the material of rubber pad 14 is softer, ball sealer 6 extrudees rubber pad 14 and can make rubber pad 14 produce deformation, the deformation of rubber pad 14 can make rubber pad 14 and 6 area of contact grow of ball sealer, simultaneously because install push pedal 15 on the ball sealer 6, and push pedal 15 is the same with the inside area of connecting pipe 2, so when the gas in the sealed tube 3 gets into connecting pipe 2, can push away push pedal 15 earlier, drive ball sealer 6 through push pedal 15 and remove, relatively more gas directly blows ball sealer 6, can make gas more easily from the inside of connecting pipe 2 entering valve body 1's inside, the sealed effect of reinforcing and the more easy effect of pressure release have been reached.

Example three: as shown in fig. 5, on the basis of the second embodiment, a sealing rod 16 which can be extended and contracted together with the pressure relief spring 5 is sleeved on the pressure relief spring 5, the front end of the sealing rod 16 is fixedly connected with the inner wall of the valve body 1, and the rear end of the sealing rod 16 is fixedly connected with the sealing ball 6.

When the valve is used, the sealing ball 6 is driven to return to the original place by the pressure relief spring 5 after pressure relief is completed, the pressure relief spring 5 can be corroded after being contacted with gas for a long time, and the corroded pressure relief spring 5 can lose the original function, so that the pressure relief spring 5 is provided with the 16 which can be stretched and contracted together with the pressure relief spring 5, the 16 can separate the pressure relief spring 5 from the inside of the valve body 1, and the condition that the pressure relief spring 5 is corroded due to the contact of the pressure relief spring 5 and the gas is avoided.

Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above-described embodiments, and many modifications are possible. Any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention should be considered as belonging to the protection scope of the present invention.
