Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described: as Figure 1-3, the control of a kind of fluid flow direction
Valve processed, by three-way body 1, rotating shaft 2, valve plate 3, Upper shaft sleeve 4, Lower shaft sleeve 5, connecting bolt 6, connecting rod 7, stop screw seat 8, spacing spiral shell
Nail 9, driving means 10, supporting plate 11 form, and driving means is arranged on supporting plate 11 and is fixedly connected in threeway, and supporting plate 11 plays
The effect in heat insulation prolongation driving means life-span；It is characterized in that: the push rod of the driving means outside three-way body 1 is with connecting rod 7 one end even
Connecing, the other end of connecting rod 7 is connected with rotating shaft 2, and Upper shaft sleeve 4 and Lower shaft sleeve 5 are separately mounted to the two ends of rotating shaft, and three-way body 1 sets
Having two gas outlets and an air intake, valve plate 3 is positioned at three-way body 1, fixes with rotating shaft 2 and be connected in the middle part of valve plate, and rotating shaft 2 is positioned at
Outlet is with on entrance center intersection, and valve plate 3 edge processes and two inclined-planes of the three-way body 1 tangent symmetry of inner chamber, and valve body is being beaten
Fit tightly with three-way body 1 inner chamber under open and close state.
Described valve plate can set, when angle one-tenth according to different needs from the centrage initial position angle of threeway inner chamber
Good economy performance when 30-45 °.
Described supporting plate 11 is fixed by bolts in threeway 1 with stop screw seat 8 simultaneously, and two stop screws are respectively mounted
In stop screw seat 8 both sides, for controlling the travel position of connecting rod 7, connecting rod 7 is consistent with the crank degree of valve plate, thus by two
Individual stop screw controls the opening and closing angle of valve plate.
The unlatching rotation direction of described valve plate is clockwise or counterclockwise.
Described driving means 10 uses cylinder, motor or gas motor.
Described gas outlet is ammonia tank connector and tail gas outlet.
By changing valve plate 3 and three-way body 1 inner chamber angle, when valve plate closed mode fluid along valve plate 3 through threeway side
Flowing out, when rotary valve open mode, fluid is flowed out along valve plate 3 by the other end of threeway.
Three-way body 1 can use the modes such as casting or Combination Welding to process, three-way body 1 inner surface needs machining to ensure
Sealing.
Stop screw seat 8 can use stamping parts to make and fix both sides stop screw simultaneously, it is ensured that the valve under open and-shut mode
Angle position adjusts.
Limited turned position regulation valve plate 3 and the body cavity angle of connecting rod 7 by stop screw 9, and then control valve
The flow percentage in two exit passageways is entered when opening.
As it is shown in fig. 7, the gas inlet of fluid flow directional control valve is connected with exhaust aftertreatment device, ammonia tank connector with
Solid ammonia storage tank is connected.
As shown in Figure 4 when ammonia storage tank tank body need not heat, driving means 10 return to initial point, by connecting rod 7 drive turn
Axle 2 forwards closed position to, and now valve plate 3 and three-way body 1 inner chamber angle are 40 ° of inclined-planes and three that just valve plate 3 edge processes
Entire body internal chamber wall fits tightly, and as shown in Figure 8, i.e. valve plate 3 closes the passage of the internal ammonia tank connector of three-way body.Gas inlet enters
The tail gas entered enters in air along valve plate 3 through tail gas outlet, prevents tail gas from entering ammonia storage tank unwanted time and causes storage
Ammonia tank is overheated, and when parking of automobile state, valve plate 3 is closed ensureing that ammonia storage tank is in safe temperature, by left side all the time
