Description

Technical Field

[0001] The utility model relates to the technical field of exhaust valves, and more specifically, to a quick exhaust valve. Background Art

[0002] A quick exhaust valve is an accessory device used in pipelines where the industrial medium is water. It is used to quickly discharge gas from the pipeline in order to improve the efficiency of water transportation equipment and protect the pipeline from deformation and rupture. It has been widely used in the field of pipeline exhaust.

[0003] When the valve cover of the existing quick exhaust valve needs to be disassembled, several corresponding nuts need to be screwed, which wastes a lot of time and cost in the process.

[0004] After searching, the quick exhaust valve disclosed in the Chinese patent with application number CN202322111044.9 is found. When the utility model needs to be installed, the two supporting members are pulled, and the supporting members drive the second spring to extend. Then the two plates are aligned with the two grooves and pushed to the specified position. At this time, the two supporting members are released, and the second spring returns to drive the supporting members to press against the valve cover to fix the valve cover. In this way, when cleaning the valve body, there is no need to screw the corresponding nuts, saving time and cost.

[0005] However, when the exhaust valve is actually used, since only two sides of the valve cover are fixed during installation, the unfixed edge of the valve cover may be looser than the fixed edge. When the internal pressure of the exhaust valve is high, the exhaust valve may leak. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick exhaust valve to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] The top of the lower valve body is fixed with a flange, and the exhaust pipe is fixed with a quick connection mechanism; the quick connection mechanism includes a lower connecting plate, the bottom of the lower connecting plate is fixedly connected to the outer side of the exhaust pipe, and the lower connecting plate is provided with a first slide groove, the outer side of the first slide groove is provided with a second slide groove, the top of the lower connecting plate is fixedly connected to the bottom of the lower connecting plate, and a sealing gasket is movably connected to the bottom of the lower connecting plate. The upper surface of the lower connecting plate is fixedly connected to the clamping ring, and an auxiliary ring is provided on the outer side of the clamping ring. Two positioning posts are fixedly connected to the outer side of the clamp, and the two positioning posts are symmetrically arranged on the outer side of the lower connecting plate. Buttons are installed on the outer sides of the two positioning posts. A plurality of clamping grooves are provided inside the clamp, and a plurality of clamping grooves are distributed in an annular array inside the clamp, an upper connecting plate is provided on the top of the lower connecting plate, a circular plate is provided on the upper surface of the upper connecting plate, and a plurality of hooks are fixedly connected to the bottom of the circular plate.

[0009] By adopting the above technical solution, the lower connecting plate and the upper connecting plate can be quickly connected, and at the same time, multiple force points are provided for the connection between the lower connecting plate and the upper connecting plate, so that the connection force between the lower connecting plate and the upper connecting plate is more uniform, avoiding air leakage caused by uneven force.

[0010] As a further description of the above technical solution: the top of the upper connecting plate is fixedly connected to a shielding cover, the bottom of the lower connecting plate is fixedly connected to a sealing ring, the inner wall of the sealing ring is fixedly connected to two gaskets, and a suspension ball is arranged inside the limiting cover.

[0011] By adopting the above technical solution: the shielding cover can disperse and guide the exhaust airflow to avoid concentrated gas spraying. After the water pushes the suspension ball to float, it can be sealed with the outside of the suspension ball through two gaskets to keep the inside of the exhaust pipe closed and prevent water from being discharged.

[0012] As a further description of the above technical solution: the bottom of the sealing ring is fixedly connected to the limiting cover, and a plurality of tapered tubes are arranged on the outside of the limiting cover, and the plurality of tapered tubes are distributed in a ring array outside the limiting cover.

[0013] By adopting the above technical solution, the air flow is dispersed through multiple tapered tubes during the discharge process, thereby reducing the impact of the gas on the suspension ball and preventing the suspension ball from being blown up by the gas.

[0014] Technical effects and advantages of this utility model:

[0015] 1. By setting up a quick connection mechanism, compared with the existing technology, the connection between the upper and lower connecting plates can be pulled synchronously, so that the connection process between the lower and upper connecting plates remains stable, avoiding the phenomenon of uneven force causing a gap in the connection between the lower and upper connecting plates, speeding up the connection speed of the lower and upper connecting plates while improving the tightness of the connection between the lower and upper connecting plates;

[0016] 2. By setting up a sealing ring, a gasket, a limit cover, a tapered tube and a suspension ball, compared with the existing technology, the exhaust gas is diverted through multiple tapered tubes, reducing the impact of the gas on the suspension ball, avoiding the phenomenon of the suspension ball being lifted by the gas to form an airtight state, and improving the stability of the quick exhaust valve.

A plurality of slots 12 are opened inside the chuck 7, and a plurality of slots 12 are distributed in a ring array inside the chuck 7. An upper connecting disk 13 is set on the top of the lower connecting disk 3, and a circular plate 14 is set on the upper surface of the upper connecting disk 13. A plurality of hooks 15 are fixedly connected to the bottom of the circular plate 14, and the plurality of hooks 15 are clamped with the plurality of slots 12 inside the chuck 7 so that the lower connecting disk 3 and the upper connecting disk 13 can maintain a tight fit. Then press the two buttons 11 to limit the chuck 7 to prevent the sliding of the chuck 7 from causing the connection between the lower connecting disk 3 and the upper connecting disk 13 to become loose.

[0026] Reference Figure 3 and Figure 4 As shown, a shielding cover 16 is fixedly connected to the top of the upper connecting plate 13, a sealing ring 17 is fixedly connected to the bottom of the lower connecting plate 3, two gaskets 18 are fixedly connected to the inner wall of the sealing ring 17, and a suspension ball 21 is arranged inside the limiting cover 19. The shielding cover 16 can divert the ejected gas to prevent the gas from impacting the operator. When the suspension ball 21 is lifted by water, it can contact the two gaskets 18 to form a sealed environment inside the exhaust pipe 2 to prevent water from being discharged.

[0027] Reference Figure 4 As shown, the bottom of the sealing ring 17 is fixedly connected to the limit cover 19, and a plurality of conical tubes 20 are arranged on the outside of the limit cover 19. The plurality of conical tubes 20 are distributed in a circular array on the outside of the limit cover 19 to divert the exhausted gas, reduce the impact of the gas on the suspension ball 21, and avoid the suspension ball 21 from being air-locked when the air inside the exhaust pipe 2 is not completely discharged.

[0028] The working principle of the present invention is as follows: when installing the quick exhaust valve, first align the multiple hooks 15 on the outside of the upper connecting disk 13 and insert them into the openings on the top of the multiple lower connecting disks 3, then pass the bottom ends of the multiple hooks 15 through the lower connecting disk 3 and enter the interior of the chuck 7, and then respectively engage with the first slide groove 4 and the second slide groove 5 at the bottom of the lower connecting disk 3 through the snap ring 8 and the auxiliary ring 9 on the top of the chuck 7, so that the chuck 7 can rotate smoothly at the bottom of the lower connecting disk 3. During the rotation of the chuck 7, the multiple grooves 12 inside the chuck 7 squeeze the inclined surfaces of the bottom of the multiple hooks 15, so that the multiple hooks 15 are pulled downward, and the multiple hooks 15 generate a downward pressure on the upper connecting disk 13 through the circular plate 14, so that the bottom groove of the upper connecting disk 13 is aligned with the lower The sealing gasket 6 on the top of the connecting plate 3 is squeezed and fitted, so that the connection between the lower connecting plate 3 and the upper connecting plate 13 remains tight, and then the two buttons 11 are pressed to fix the outer side of the lower connecting plate 3, so that the chuck 7 maintains the stability of the connection in the process of driving the multiple hooks 15 to pull down. Thereafter, when the exhaust valve is in use, in the process of exhausting through the exhaust pipe 2, the gas enters the interior of the limit cover 19 through the multiple conical tubes 20, so that the high-speed flowing gas is dispersed by the multiple conical tubes 20, reducing the impact force of the gas on the suspension ball 21, and then discharged from the top of the upper connecting plate 13 through the lower connecting plate 3 and the upper connecting plate 13. When water passes through the exhaust pipe 2, the water causes the suspension ball 21 to float and fit and seal with the two gaskets 18 to prevent water from leaking from the exhaust valve.
