Because the utility model discloses a set up air inlet, gas outlet and the mouth of blowing on the valve barrel body, its air inlet and intake -tube connection, its gas outlet is connected with the reactor monomer, its mouthful jetting valve union coupling of blowing, wherein the air inlet is the normal open, the gas outlet and the occasion of oral sex for the switch -on of blowing to the demand of cleaing away catalyst laying dust in the denitration reaction device has been satisfied, moreover the utility model discloses a valve plate adopts cone combined with with the internal chamber of valve barrel wall, and sealing performance is good, simple structure.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of normal pressure Pneumatic three-way valve.
Background technique
In denitration reaction device, owing to containing a certain amount of dust in air-flow, the catalyst surface in Benitration reactor often there will be laying dust phenomenon, affects the utilization efficiency of catalyzer, needs the laying dust removing catalyzer, needs to use valve to switch for this reason.The valve that traditional denitration reaction device uses is push-pull valve, and the phenomenon that track leaks gas in use usually appears in this valve, and make air pressure impaired, and application is limited, ash-removal effect is bad.Dealer is badly in need of a kind of valve and is replaced traditional push-pull valve for this reason.
Model utility content
The purpose of this utility model is to provide that a kind of structure is simple, the normal pressure Pneumatic three-way valve of good seal performance.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of normal pressure Pneumatic three-way valve, comprises valve barrel body, valve plate, valve plate connecting rod, cylinder block, cylinder; The cylinder body of described cylinder is fixed on cylinder block, and cylinder block is fixed on valve barrel body, the piston rod rod end of cylinder by valve plate connecting rod and valve plate affixed, valve plate kink is nested with in valve barrel body; Described valve barrel body offers suction port, air outlet and inflatable mouth, and its suction port is connected with suction tude, and its air outlet is connected with reactor monomer, and its inflatable mouth is connected with blowing valve pipe.
Described valve barrel body be tubular member, its top and bottom are opened wide, the open port of upper end is installed a valve upper cover, cylinder piston rod rod end is connected with valve plate connecting rod, valve plate connecting rod is connected with the valve plate slipped in valve barrel body through after valve upper cover from top to bottom, the open at its lower end port of valve barrel body is air outlet, the lower end of valve barrel body by flange plate and reactor monomer affixed, the air outlet of valve barrel body and reactor monomer inner space, the sidewall of valve barrel body offers suction port and inflatable mouth respectively.
On described valve barrel intracoelomic cavity wall, the below of suction port is provided with a circle conic steps face; Described valve plate outer rim is inverted cone, and valve plate inverted cone outer rim coordinates with the conic steps face on valve barrel intracoelomic cavity wall.
After adopting such scheme, due to valve barrel body of the present utility model offering suction port, air outlet and inflatable mouth, its suction port is connected with suction tude, its air outlet is connected with reactor monomer, and its inflatable mouth blowing valve pipe connects, and wherein suction port is normal open, the occasion that air outlet and inflatable mouth are switched in alternation, thus meet the demand removing catalyzer laying dust in denitration reaction device, and valve plate of the present utility model and valve barrel intracoelomic cavity wall adopt cone match, and good seal performance, structure are simple.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is plan view of the present utility model;
Fig. 3 is fundamental diagram of the present utility model;
Fig. 4 is the utility model different operating view.
Embodiment
As shown in Figure 1 and Figure 2, the utility model is a kind of normal pressure Pneumatic three-way valve, comprises valve barrel body 1, valve plate 2, valve plate connecting rod 3, cylinder block 4, cylinder 5, valve upper cover 6.
The cylinder body of described cylinder 5 is fixed on cylinder block 4, and cylinder block 4 is fixed on valve barrel body 1.
Described valve barrel body 1 be tubular member, its top and bottom are opened wide, the open port 11 of upper end is installed a valve upper cover 6, cylinder 5 piston rod rod end is connected with valve plate connecting rod 3, valve plate connecting rod 3 is fixedly connected with the valve plate 2 slipped in valve barrel body 1 through after valve upper cover 6 from top to bottom, the open at its lower end port one 2 of valve barrel body 1 is air outlet 12, the lower end of valve barrel body 1 is affixed by flange plate 7 and reactor monomer 10, air outlet 12 and reactor monomer 10 inner space of valve barrel body 1, the sidewall of valve barrel body 1 is offered suction port 13 and winding-up mouth 14 respectively, suction port 13 is connected with suction tude 20, winding-up mouth 14 is connected with blowing valve pipe 30, at blowing valve pipe 30 the other end, blowing valve is installed.
On described valve barrel body 1 internal chamber wall, the below of suction port 13 is provided with a circle conic steps face 15; Described valve plate 2 outer rim is inverted cone, and valve plate 2 inverted cone outer rim coordinates with the conic steps face 15 on valve barrel body 1 internal chamber wall, makes valve plate 2 closing tight with the conic steps face 15 on valve barrel body 1 internal chamber wall declined.
As shown in Figure 3, Figure 4, working principle of the present utility model:
1, online starting impulse deduster: when normally working, valve plate 2 is mentioned, and waste gas enters from suction port 13, because winding-up mouth 14 has installed blowing valve, air-flow can not flow out from winding-up mouth.When deashing work starts, valve plate 2 falls, and high pressure draught enters from winding-up mouth 14, and air-flow now can not flow out from suction port, reaches the object of deashing.
2, denitration reaction device: owing to containing a certain amount of dust in air-flow; catalyst surface in Benitration reactor often there will be laying dust phenomenon; affect the utilization efficiency of catalyzer; the utility model is connected with valve rod by cylinder; the switch of valve is controlled automatically; directly can remove the laying dust of catalyzer, not affect again the normal operation of equipment.
The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
