For solve existing air-valve monomer area little, need deficiency such as assembly unit use, the utility model that a kind of simple in structure, novel pneumatic air-valve of being easy to produce is provided.This model utility structure can not only realize the making of large size monolithic valve body, and can easily produce the supporting pneumatic actuator of different moments of torsion.
The technological scheme that its technical problem that solves the utility model adopts is: adopt the single-acting cylinder of standard to dispose composition actuators such as corresponding main pivoted arm and solenoid valve; Large-area valve body adopts in the integral frame dividing plate form is set; With the valve plate of axis connection dividing plate both sides, the secondary pivoted arm of axle head and connecting rod link to each other and realize parallel or relative open function.Plurality of advantages such as this technological scheme has simple in structure, adapts to all size size, and material, the pneumatic element of use are purchased easily, and cost of production is low, makes easily, and is easy to use, reliable.
Pneumatic actuator is the power that air-valve finishes unlatching, cuts out.It is made up of single-acting cylinder, cylinder block, breeches joint and the main pivoted arm of standard.When pressurized air stretches out cylinder column by electromagnetic valve or withdraws, drive the main pivoted arm be twisted together with it and rotate, main pivoted arm drives driving shaft by flat key and is fixed on valve plate rotation on the axle, finishes unlatching, closing motion.Driving shaft all is equipped with the secondary pivoted arm of same size with other countershafts and links to each other by connecting rod, makes the valve plate that is fixed on the countershaft finish the action of open and close equally.
The valve body of air-valve is an overall structure: be welded into housing with the metal section that is converted into the C type, again according to the size of valve body width W, dividing plate is set in housing, and dividing plate is divided into width with valve body and is not more than 1.2 meters unit, to guarantee that wherein valve plate is not because of the long resistance to flexure that reduces.On the height H direction of valve body, housing and dividing plate have axis hole and installation shaft bearing and bearing in order to support valve shaft.
Concrete technological scheme of the present utility model is: the lateral mid-point of top and bottom housing is welded with longitudinal baffle; Vertically have a spindle hole and a plurality of countershafts hole in the housing, weld bearing support and axle sleeve is installed with the major-minor axis hole is concentric, corresponding position also has axis hole and axle sleeve is installed on the dividing plate, and housing is concentric with the axle sleeve on the dividing plate; Cylinder is connected with cylinder block and is installed on the bearing, and bearing is fixed on vertical housing outside, and the breeches joint of wire connection and main pivoted arm are twisted together on the cylinder column; Main pivoted arm is connected with main shaft, and main shaft all is equipped with the secondary pivoted arm of same size with other countershaft and links to each other by connecting rod; Valve plate is combined by the steel plate of 2 compression mouldings, penetrates main shaft and countershaft in the center hole of valve plate, and block with sealing plate in valve plate and housing gap; Can limit main pivoted arm and open the adjusting overhang of final position and the top that limiting board is installed in horizontal housing, the output terminal of valve shaft be equipped with valve plate rotate synchronously and can and the position limit switch limiting stopper of colliding; Suction tude connects the suction port of solenoid valve, and the relief opening of solenoid valve is connected with silencing apparatus respectively, inserts cylinder after solenoid valve and series flow control valve link.
The beneficial effects of the utility model are: 1. can make the following unit valve body of area 8 square meters, having solved in the past need be with the defective of many assembly units; 2. select the standard cylinder of different cylinder diameters for use, promptly can be assembled into the pneumatic actuator of various moments of torsion, be not subjected to the restriction of special-purpose air-valve final controlling element specification.Can satisfy monomer air-valve area big, be swift in motion reliable, and the requirement of safety anti-explosive.
