Embodiment
It is big that the utility model aims to provide a kind of circulation area, and the pneumatic blinds valve that can adjust with the size of handling air quantity of perforate size.Below in conjunction with drawings and Examples the utility model is done detailed explanation.
To shown in Figure 4, the pneumatic blinds valve 1 of the utility model comprises rectangular valve body 2 as Fig. 2, and certain described valve body 2 also can adopt square structure, is provided with at least one rotating valve shaft 3 on valve body 2; Be fixed with valve plate 4 on valve shaft 3, valve plate 4 and described valve body 2 are suitable, have good gas tightness during with assurance valve plate 4 closures; One end of described valve shaft 3 stretches out outside the described valve body 2 and with a wherein end of crank 5 fixedlys connected, and the piston rod 7 of the other end of described crank 5 and cylinder 6 is rotationally connected; The cylinder body of described cylinder 6 is horizontally fixed on the described valve body 2, and cylinder is connected with source of the gas.
Wherein, described valve shaft 3 is two or three and be arranged in parallel; Valve shaft 3 in the present embodiment is three, all is fixed with valve plate on each valve shaft, cooperatively interacts between each valve plate, plays seal action when each valve plate is closed.
One end of each valve shaft stretches out described valve body, and fixedlys connected with a wherein end of described crank in this end of stretching out one of them valve shaft of described valve body; At present embodiment, fixedly connected with a wherein end of described crank in the end that is positioned at the valve shaft of the valve body leftmost side.
In addition, also fixedly connected with a wherein end of pull bar 8 separately in the end that each valve shaft 3 stretches out described valve body 2, the arranged direction unanimity of described each pull bar 8, and the other end of described each pull bar 8 is hinged on the same connecting rod 9.
The piston rod 7 flexible pulling cranks 5 of cylinder 6 rotate, and crank 5 drives the valve shaft of fixedlying connected with it and rotates, and this valve shaft is again by 9 actions of pull bar fixedly connected on it 8 drivening rods.The action of connecting rod 9 drives the rotation of other valve shafts again, like this, by stretching of cylinder piston rod, just can control the unlatching and closure of each valve plate, thereby can realize the Flow-rate adjustment to the air-flow that flows through valve body.
The stroke of adjusting cylinder is corresponding with the state of valve plate unlatching, and then guarantees the seal that valve plate is closed and the maximality of unlatching.Cylinder is worked simultaneously by PLC control is one or more, and is convenient and simple for operation reliable.
The embodiment that the utility model is used is the parts as the environmental protection industry (epi) sack cleaner, is installed on air-purifying chamber exhaust outlet position, guaranteeing when the deashing of each chamber of deduster, and valve closing, this chamber is in isolation; Not during deashing, valve opening, this chamber can reach certain outlet wind speed.It is that sack cleaner can be realized indispensable vitals in off-line ash-clearing or the on-bne repair function.
Be provided with sealing case 10 at the top of described valve body.The effect of sealing case 10 is to solve after the blinds valve installs, with the sealing problem of case top.
Simple for guaranteeing the installation of blinds valve, maintenance is convenient, has opened a square hole on deduster housing top board, the installation and the taking-up of enough blinds valves.Sealing case is fixed on the square hole place, is connected with blinds valve seal cover plate by flange, has guaranteed blinds valve seal and design philosophy easy for installation.The design of valve body should be convenient to make also from simple consideration, requires coupling shaft that the back is installed again and rotates flexibly, has added the cast iron wear-resistant sleeve in bearing support inside, and cast iron can play lubricated effect to axle in rotation process.Increased sealed cover at the top, the blinds valve is installed after, guaranteed the sealing at top.The valve plate of blinds valve is made into two or three usually, connects by valve shaft respectively, links together by connecting rod again between each valve shaft, along with the motion of cylinder, drives all valve plates and rotates together, and the slewing area of valve plate is the 0-90 degree.
And the pneumatic blinds valve arrangement of the utility model has adopted rectangular opening, and its perforated area is big, and resistance is little.The blinds valve adopts biplate or multi-disc valve plate, and coupling shaft rotates, and opens valve plate, relatively flexibly.And because the blinds valve stands up, closely be connected, need do not take too large space, reduced the physical dimension of deduster casing with the flange of pure qi (oxygen) case end.
The pneumatic blinds valve of the utility model has solved the exhaust outlet demand that present domestic environmental protection bag-type dust collecting equipment is handled big air quantity, and its circulation area is big, and resistance is little, and compact structure can substitute the effect of poppet valve in the dedusting industry; It is simple, quick by the action of PLC timing or level pressure difference control cylinder, is convenient to off-line ash-clearing and switches big exhaust gas volumn.
The above; it only is embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
