Description
Technical field
The utility model is related to valve manufacture fields, and in particular to a kind of special butterfly valve of desulfurization.
Background technology
Butterfly valve refers to that for disk, a kind of valve of open and close is reached around valve shaft rotation for closure member, main on pipeline
Play cut-out and throttling action.Existing butterfly valve valve rod is whole radical, through closure member, leads to the open and close power of closure member
Square is big, and valve rod is easily damaged, and butterfly valve service life is low；In addition it also needs to add in sulfuric acid in certain sulfur removal technologies, and it is sour
Butterfly valve is just easy to be corroded under property environment.
Utility model content
To solve the above problems, the utility model is implemented according to following technical scheme：
A kind of special butterfly valve of desulfurization, it is described including driving device, valve rod, valve plate, valve body and leak detection alarm
Valve body and the valve plate are equipped with line with rubber layer with media contact part；The valve body upper right quarter is equipped with leak detection alarm, institute
Body base is stated equipped with location hole；The valve plate is located at the valve body center, and the valve rod is by keyed upper valve rod and keyed
Lower valve rod forms, and the valve plate upper and lower ends are equipped with the hole with keyway, and valve plate upper end is stretched into the keyed one end of the upper valve rod
Kong Zhong, the other end are connect with driving device, and the keyed one end of the lower valve rod is stretched into the hole of valve plate lower end, and the other end stretches into valve
In the location hole of body bottom；The valve body lower portion is equipped with valve seat.
Further, the depth of the body base location hole is 1.5-2.5 times of lower valve rod sectional dimension.
Further, the valve body four corners are equipped with fixing bolt.
Further, the seat bottom portion is equipped with foundation bolt.
The beneficial effects of the utility model：In the utility model, upper valve rod, which serves, transmits torque, and lower valve rod plays positioning and makees
With reducing the torque of the open and close of valve plate so that upper and lower valve stem is fragile, increases the service life of butterfly valve；Line with rubber layer
Design effectively raise the corrosion resistance of butterfly valve；In addition, the design of leak detection alarm can detect leakage in time, in advance
Accident prevention occurs, securely and reliably.Rational in infrastructure, performance is good, low manufacture cost, suitable for batch production.

Specific embodiment
One embodiment of the utility model is described further below in conjunction with the accompanying drawings.
The special butterfly valve of a kind of desulfurization as shown in Figure 1, including driving device 1, valve rod, valve plate 5, valve body 4 and leakage
It detects alarm 8, valve body 4 and valve plate 5 and is equipped with line with rubber layer 6 with media contact part；4 upper right quarter of valve body is equipped with leak detection report
Alert device 8,4 bottom of valve body are equipped with location hole；Valve plate 5 is located at 4 center of valve body, and valve rod is by under keyed 9 upper valve rod 2 and keyed 9
Valve rod 3 forms, and 5 upper and lower ends of valve plate are equipped with the hole with keyway, and one end of upper valve rod 2 keyed 9 is stretched into the hole of 5 upper end of valve plate,
The other end is connect with driving device 1, and one end of the lower valve rod 3 keyed 9 is stretched into the hole of 5 lower end of valve plate, and the other end stretches into valve
In 4 bottom location hole of body；4 lower part of valve body is equipped with valve seat 7；The depth of 4 bottom location hole of valve body is 3 sectional dimension of lower valve rod
1.5-2.5 times, 4 four corners of valve body are equipped with fixing bolt 10, and 7 bottom of valve seat is equipped with foundation bolt 11.
When in use, upper valve rod 2 is driven to rotate by device of rotation driving 1, upper valve rod 2 drives valve plate 5 to rotate, and reaches out
Open the purpose with closing.Upper valve rod 2 plays a part of to transmit torque, and lower valve rod 3 plays positioning, reduces valve plate 5 and opens and close
The torque closed, valve body 4 are fixed by the fixing bolt 10 of four corners, and pedestal schedules ground by foundation bolt solid 11.
The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above, it is right
For those skilled in the art, it is clear that the utility model is not limited to the details of above-mentioned exemplary embodiment, and is not carrying on the back
