Specific embodiment
The present invention will be further described with reference to the accompanying drawing: as shown in Figs. 1-3.A kind of flow direction and flow control
Valve, by three-way body 1, shaft 2, valve plate 3, Upper shaft sleeve 4, Lower shaft sleeve 5, connection bolt 6, connecting rod 7, stop screw seat 8, limit spiral shell
Nail 9, driving device 10, supporting plate 11 form, and driving device is mounted on supporting plate 11 and is fixedly connected in threeway, and supporting plate 11 plays
The heat-insulated effect for extending the driving device service life；It is characterized by: the mandril of the driving device outside three-way body and 7 one end of connecting rod connect
It connects, the other end of connecting rod 7 is connect with shaft 2, and Upper shaft sleeve 4 and Lower shaft sleeve 5 are separately mounted to the both ends of shaft, set on 1 body of threeway
There are two gas outlet and an air intake, valve plate 3 is located in threeway 1, is fixedly connected in the middle part of valve plate with shaft 2, shaft 2 is located at
With on entrance center intersection, 3 edge of valve plate is processed to be opened with tangent symmetrical two inclined-planes in 1 inner cavity of threeway, valve body for outlet
It is fitted closely under closed state with 1 inner cavity of threeway.
The valve plate and the center line initial position angle of threeway inner cavity can according to it is different need to set, when angle at
Good economy performance at 30-45 °.
The supporting plate 11 and stop screw seat 8 is fixed by bolts to simultaneously in threeway 1, and two stop screws are installed respectively
In 8 two sides of stop screw seat, for the travel position of controls connecting rod 7, connecting rod 7 is consistent with the crank degree of valve plate, thus by two
A stop screw controls the opening and closing angle of valve plate.
The unlatching rotation direction of the valve plate is clockwise or counterclockwise.
The driving device 10 is using cylinder, stepper motor or gas motor.
The gas outlet is ammonia tank connector and tail gas outlet.
By changing valve plate 3 and 1 inner cavity angle of threeway, in valve plate closed state, fluid is along valve plate 3 through one effluent of threeway
Out, in rotary valve opening state, fluid is flowed out along valve plate 3 by the other end of threeway.
Threeway 1 can be used that the modes such as casting or Combination Welding are processed, threeway inner surface need to be machined to guarantee to seal
Property.
Stamping parts production while fixed two sides stop screw can be used in stop screw seat 8, guarantees the valve under open and-shut mode
Angular position adjustment.
Valve plate 3 and body cavity angle, and then control valve are adjusted by the turned position that stop screw 9 limits connecting rod 7
Into the flow percentage in two exit passageways when opening.
As shown in fig. 7, the gas inlet of fluid flow directional control valve is connected with exhaust aftertreatment device 12, ammonia tank connector
It is connected with solid ammonia storage tank 13.
As shown in Figure 4 when ammonia storage tank tank body does not need heat, driving device 10 return to origin, by connecting rod 7 with turn
Axis 2 goes to closed position, and valve plate 3 and 1 inner cavity angle of threeway are 40 ° of just inclined-plane that processes of 3 edge of valve plate and threeways at this time
Internal cavity wall fits closely, as shown in figure 8, the channel of the i.e. closing of valve plate 3 three-way body inside ammonia tank connector.Gas inlet enters
Tail gas be discharged into atmosphere along valve plate 3 through tail gas outlet, prevent tail gas enter when unwanted ammonia storage tank cause store up ammonia
Tank overheat, in parking of automobile state, valve plate 3 is in close state always guarantees that ammonia storage tank is in safe temperature, is limited by left side
Position screw 9 can limit the turned position of connecting rod to adjust the gap value of closed state lower valve plate 3 Yu triple-valve body, guarantee to seal
Mitigate valve plate abrasion while demand and improves the service life.
As shown in Figure 5 when ammonia storage tank tank body needs heat, the mandril of driving device 10 be ejected, driven by connecting rod 7
Shaft 2 goes to open position, and valve plate 3 closes offgas outlet wing passage inside three-way body.The tail gas entered from gas inlet passes through
Ammonia tank connector is passed through guarantee ammonia tank institute calorific requirement in ammonia storage tank.
Closed state lower valve plate 3 can be adjusted by limiting the turned position of connecting rod by left side stop screw 9 as shown in Figure 6
When angle between triple-valve body is less than 40 °, the mandril of driving device 10 is ejected, and valve plate 3 is in half open and-shut mode.From tail gas
The tail gas part that entrance enters is passed through in ammonia storage tank by ammonia tank connector, is partially discharged into atmosphere by tail gas outlet,
While guaranteeing that ammonia storage tank institute calorific requirement meets, extra exhaust gas is discharged into atmosphere, system exhaust resistance is reduced, reduces flow
Application valve body on-off times prolong the service life.
