Abstract
The utility model relates to the technical field of environmental engineering, in particular to a liquid-sealed smoke switch valve device, which has higher sealing performance and more flexible operation compared with the traditional smoke valve and greatly reduces the occurrence of toxic gas leakage accidents; the smoke switch valve comprises a smoke switch valve body, a liquid inlet valve, a liquid outlet valve and a liquid level meter, wherein the lower end of a smoke inlet in the smoke switch valve is higher than the lower end of a smoke outlet, and the liquid level meter is arranged on the outer wall of the switch valve body. The flue gas in the flue is switched on and off by means of liquid seal. When the flue needs to be switched to a passage, a liquid discharge valve of the device is opened to discharge the liquid. At the moment, the device forms a same channel, and the flue gas flows out of the device along the channel and enters the outlet flue. When the flue needs to be switched to be a closed circuit, the liquid inlet valve of the device is opened to inject water into the device, and the liquid submerges the liquid outlet to block the flue gas, so that the purpose of closing the flue gas is achieved.
Description
Technical Field
The utility model relates to a technical field of environmental engineering especially relates to a liquid seal formula flue gas switch valve device.
Background
The flue gas valve is widely used as a flow dividing and converging or flow direction switching device of media in pipelines of coal chemical industry, petrochemical industry, rubber, papermaking, pharmacy and the like. The traditional flue gas valve has poor sealing performance and loose flue gas sealing, and safety accidents can be caused when toxic gas leaks. In addition, the corrosion of strong corrosive gas to the valve is difficult to avoid, the valve is seriously corroded after long-time operation, and the valve cannot be normally opened or closed, the sealing performance is influenced, and the like.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a liquid seal formula flue gas ooff valve device specifically is flue gas inlet lower extreme is higher than the exhanst gas outlet lower extreme in the ooff valve.
The utility model discloses a liquid seal formula flue gas ooff valve device, including flue gas ooff valve main part, business turn over liquid valve and level gauge.
The utility model discloses a liquid seal formula flue gas ooff valve device, flue gas inlet lower extreme is higher than the flue gas outlet end in its ooff valve, and the level gauge sets up on ooff valve main part outer wall. The flue gas in the flue is switched on and off by means of liquid seal. When the flue needs to be switched to a passage, a liquid discharge valve of the device is opened to discharge the liquid. At the moment, the device forms a same channel, and the flue gas flows out of the device along the channel and enters the outlet flue. When the flue needs to be switched to be a closed circuit, the liquid inlet valve of the device is opened to inject water into the device, and the liquid submerges the liquid outlet to block the flue gas, so that the purpose of closing the flue gas is achieved.
The utility model discloses a liquid seal formula flue gas ooff valve device installs the level gauge on the device, can detect the liquid level in the device. In addition, the device can realize manual operation or on-line automatic operation, and only the liquid inlet valve and the liquid outlet valve are required to be set as manual valves or automatic valves.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a flue gas inlet lower extreme is higher than the form of flue gas outlet end to the form through the liquid seal carries out the switching of opening and closing to the flue gas in the flue, has increased substantially the leakproofness of device, reduces the corruption of strong corrosive gas to the valve member, has improved the life-span of valve, reduces the influence to production.

Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
As shown in fig. 1, the utility model discloses a liquid seal formula flue gas ooff valve device, flue gas inlet 1, exhanst gas outlet 2, inlet valve 3, inlet 4, level gauge 5, leakage fluid dram valve 6, leakage fluid dram 7, overflow mouth 8, flue gas ooff valve main part 9. The flue gas inlet 1 of the flue gas switch valve is connected with flue gas generating equipment, the flue gas outlet 2 of the flue gas switch valve is connected with flue gas processing equipment, the liquid level meter 5 is positioned on the outer wall of the valve main body, and the liquid inlet valve 3 and the liquid outlet valve 6 can be set to be manual valves or automatic valves.
The utility model discloses a liquid seal formula flue gas ooff valve device, 1 lower extreme of flue gas inlet is higher than 2 lower extremes of exhanst gas outlet in its ooff valve, and level gauge 5 sets up on ooff valve main part outer wall. The flue gas in the flue is switched on and off by means of liquid seal. When the flue needs to be switched to a passage, the liquid discharging port 7 of the device is opened, and the valve 6 is opened to discharge the liquid. At the moment, the device forms a same channel, and the flue gas flows out of the device along the channel of the flue gas inlet 1 and enters the flue gas outlet 2. When the flue needs to be switched to be a closed circuit, the liquid inlet valve 3 of the device is opened to inject water into the device, and the liquid submerges the lower end of the flue gas outlet 2 to block the flue gas, so that the aim of closing the flue gas is fulfilled.
The utility model discloses a liquid seal formula flue gas ooff valve device installs level gauge 5 on the device, can detect the liquid level in the device. In addition, the device can realize manual operation or on-line automatic operation, and only the liquid inlet valve 3 and the liquid outlet valve 6 are required to be set as manual valves or automatic valves.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
