Abstract
The utility model discloses a mechanical bypass valve for the tail gas purifying device of a diesel generating set, which comprises a bolt, a valve seat, an O-shaped ring, a valve block, a spring, a valve cover and a nut. The valve seat and the valve block are fixed by the bolt. The O-shaped ring is arranged between the valve seat and the valve block. The spring and the valve cover are sleeved on the bolt. The nut and the bolt are connected together. According to the technical scheme of the utility model, the cost of the safety mechanical bypass valve for the tail gas purifying device of the diesel generating set is lowered, and the installation space is saved.
Description
Technical field
The utility model relates to a kind of tail gas from diesel electric generator purification plant, particularly relates to a kind of mechanical bypass valve of tail gas from diesel electric generator purification plant.
background technique
What the mechanical bypath valve of generator set exhaust gas cleaner mainly used in the market is wafer type hard seal butterfly valve, comprises manually opened, electronic automatic unlatching and pneumatic automatic unlatching.Though which kind of mode, not only price high, need to be equipped with extra device, and exhaust temperature is had to upper limit requirement, General Requirements is lower than 350 ℃, otherwise can cause sealing not exclusively, produces gas leakage.
model utility content
Technical problem to be solved in the utility model is to provide a kind of mechanical bypass valve of tail gas from diesel electric generator purification plant, it reduces the cost of the safe bypass of generator set exhaust gas cleaner, it reduces the cost of the safe bypass of generator set exhaust gas cleaner, saves installing space.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of mechanical bypass valve of tail gas from diesel electric generator purification plant, it is characterized in that, it comprises bolt, valve seat, O type circle, valve block, spring, valve gap, nut, between valve seat and valve block, be bolted, O type circle is between valve seat and valve block, spring, valve gap are enclosed within on bolt, and nut is connected with bolt.
Positive progressive effect of the present utility model is: the cost that, reduces the safe bypass of generator set exhaust gas cleaner; Two, save installing space; Three, less demanding to exhaust temperature; Four, according to setting pressure, bypass valve is opened automatically, without being equipped with other devices and operator.
accompanying drawing explanation
Fig. 1 is the structural representation of the mechanical bypass valve of the utility model tail gas from diesel electric generator purification plant.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the mechanical bypass valve of the utility model tail gas from diesel electric generator purification plant comprises bolt 1, valve seat 2, O type circle 3, valve block 4, spring 5, valve gap 6, nut 7, fixing by bolt 1 between valve seat 2 and valve block 4, O type circle 3 is between valve seat 2 and valve block 4, spring 5, valve gap 6 are enclosed within on bolt 1, and nut 7 is connected with bolt 1.
In the time that back pressure is too high, the pressure that generator set tail gas causes valve block 4 can make spring 5 compress, and valve block 4 is separated with the O type circle 3 on valve seat 2, and generator set tail gas, by the gap between valve block 4 and O type circle 3, is discharged in air through bypass tube; Carry out the reduction length (deformation quantity) of Regulation spring 5 by adjusting valve gap 6 and nut 7, thus the pressure that regulates valve block 4 to open.The utility model reduces the cost of the safe bypass of generator set exhaust gas cleaner, saves installing space.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
