Abstract
The utility model discloses a kind of bypath system, this system comprises housing, the first lift valve, the second lift valve, electric check valve, described housing is F shape structure, the first valve port is provided with in the vertical component of described housing, the horizontal component of described housing is provided with the second valve port, and the position of described second valve port is higher than the position of described first valve port; Described housing is arranged the first lift valve, the second lift valve, the valve plate of described first lift valve coordinates with the first valve port, and the valve plate of described second lift valve coordinates with the second valve port; Described electric check valve is arranged on the side of housing.The utility model solve valve plate and sealing valve port tight time cause discharging the problem exceeded standard, the utility model in off position time, even if valve plate and sealing valve port are not sternly, also just cause deduster to leak out, the discharge of deduster can never be affected.
Description
Technical field
The utility model belongs to deduster technical field, is specifically related to a kind of bypath system.
Background technology
Along with the dynamics of Environmental protection is progressively strengthening, Air Pollutant Emission requires more and more harsher.In order to reach the requirement of low emission, enterprise selects bag dust collector or electrostatic fabric filter one after another.Enterprise, in order to tackle emergency case (temperature exceeds filter bag allowable temperature), requires that bag dust collector or electrostatic fabric filter have bypath system, to be protection filter bag at high temperature, reduces enterprises' loss.
Existing bypath system valve port and valve plate in manufacture and installation process are easily out of shape, and cause valve plate poorly sealed, cause former flue gas to reveal, discharge exceeds standard.
Utility model content
In view of this, main purpose of the present utility model is to provide a kind of bypath system.
For achieving the above object, the technical solution of the utility model is achieved in that
The utility model embodiment provides a kind of bypath system, this system comprises housing, the first lift valve, the second lift valve, electric check valve, described housing is F shape structure, the first valve port is provided with in the vertical component of described housing, the horizontal component of described housing is provided with the second valve port, and the position of described second valve port is higher than the position of described first valve port; Described housing is arranged the first lift valve, the second lift valve, the valve plate of described first lift valve coordinates with the first valve port, and the valve plate of described second lift valve coordinates with the second valve port; Described electric check valve is arranged on the side of housing.
In such scheme, described first valve port is communicated with former flue, and described second valve port is communicated with flue.
Compared with prior art, the beneficial effects of the utility model:
The utility model solve valve plate and sealing valve port tight time cause discharging the problem exceeded standard, the utility model in off position time, even if valve plate and sealing valve port are not sternly, also just cause deduster to leak out, the discharge of deduster can never be affected.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model embodiment provides a kind of bypath system, as shown in Figure 1, this system comprises housing 1, first lift valve 2, second lift valve 3, electric check valve 4, described housing 1 is F shape structure, the first valve port 5 is provided with in the vertical component of described housing 1, the horizontal component of described housing 1 is provided with the second valve port 6, and the position of described second valve port 6 is higher than the position of described first valve port 5; Described housing 1 is arranged the first lift valve 2, second lift valve 3, the valve plate of described first lift valve 2 coordinates with the first valve port 5, and the valve plate of described second lift valve 3 coordinates with the second valve port 6; Described electric check valve 4 is arranged on the side of housing 1.
Described first valve port 5 is communicated with former flue, and described second valve port 6 is communicated with flue.
The course of work of the present utility model:
As shown in Figure 1, when the utility model is closed, described first lift valve 2 and the second lift valve 3 are closed, and cut off former flue and flue, described electric check valve 4 is opened, and introduce air, now, and P in the utility model
1-P
0=house outlet pressure+resistance of the filter bag, P
2-P
0=house outlet pressure, pressure P in housing 1 of the present utility model
0be greater than former flue pressure P
1with flue pressure P
2even if now two valve plates are all not closed completely, also do not have former flue gas and directly enter flue, the discharge effectively avoiding bypass valve to be not closed completely causing exceeds standard; Described P
1be the pressure (relative pressure is less than zero) of (i.e. former flue) below the first valve port 5, described P
0for the pressure (relative pressure is zero) in housing 1, described P
2be the pressure (relative pressure is less than zero) of (i.e. flue) below the second valve port 6;
When the utility model is opened, electric check valve cuts out, isolated air, and described first lift valve 2 and the second lift valve 3 are opened, and are incorporated in flue by former flue gas from former flue, now, and P in the utility model
1=P
2=P
0=house outlet pressure, pressure P in housing 1 of the present utility model
0equal former flue pressure P
1equal flue pressure P
2equal house outlet pressure.
The above, be only preferred embodiment of the present utility model, is not intended to limit protection domain of the present utility model.
