Abstract
The utility model discloses a pneumatic butterfly valve for pumps of fluid tanks, mainly composed of a cylinder body and a piston arranged in the cylinder. Both ends of the cylinder body are provided with pneumatic heads. The cylinder body is respectively provided with air inlet and outlet holes. Two chambers are arranged in the cylinder body. Two pistons connected to the same axis are arranged in the cylinder body. The utility model has the advantages of compact structure, light weight, good hermetic sealing property, long service life, easy installation and convenient maintenance. The utility model is mainly applied to pneumatic ash transmission system.
Description
The utility model relates to a kind of fluidized pump Pneumatic butterfly valve.
Be used for the discharge valve that the Pneumatic ash conveying system uses at present, mostly adopt pumping board formula discharge valve, its shortcoming is because Pneumatic ash conveying system discharge pressure height, the dust transporting velocity reaches more than 12 meter per seconds, the dust that pumping board formula discharge valve is often carried at a high speed destroys, working life generally about 20 days, as select for use ball valve then the life-span shorter.Pumping board formula discharge valve is because of selecting double-acting cylinder for use, and volume is big, weight is big, switching speed is slow, poor air-tightness, and manufacture cost height.
The purpose of this utility model is to provide a kind of modern design at above-mentioned shortcoming, compact structure, and beautiful shape, switch motion is neat and tidy, and tightness is good, the fluidized pump Pneumatic butterfly valve of long service life.
The utility model is the fluidized pump Pneumatic butterfly valve.For achieving the above object, its Pneumatic butterfly valve mainly is made up of pneumatic head and the valve body that is placed in the band seal ring in the pneumatic head, main cylinder body and the lid that is placed in tooth axle, piston and cylinder body two ends in the cylinder body of adopting of its pneumatic head formed, is provided with inlet, outlet in the middle of the described cylinder body, is provided with two pistons in the cylinder body and is placed on the same tooth axle.Also be provided with left and right two cavity volumes in the cylinder body.
The utility model compared with prior art has following distinguishing feature and progress.1. the utility model adopts the pneumatic head of tooth axle double-piston type tooth bar rotary structure, and cylinder diameter is little, and moment of torsion is big, and is in light weight, and suction pressure is little, and (0.4～0.8Mpa) rotating speed is fast, and the way of output is the square opening plug-in type, and it is adjustable to draw journey, compact structure, beautiful shape.Pneumatic head is provided with two air inlet/outlets, an inlet hole is by two cavity volumes, be used to open butterfly valve, and another air outlet hole is used to close butterfly valve by the two-piston face, wherein butterfly valve moment opens about 2 seconds of time kind and reaches complete opening, has avoided resembling the former plate valve one of taking out and has opened and suffer promptly that high pressure dust stream impacts and the shortcoming destroyed.2. the utility model tightness is good, and long service life can reach more than 4 months under operating at full capacity.3. easy to maintenance.Can reach more than 1 year pneumatic working life, still can continue to use after maintenance, and butterfly valve has interchangeability, and installation, maintenance is convenient, and system-down is short engineering time, can not bring negative effect to power plant.The utility model is mainly used in the Pneumatic ash conveying system.Be specially adapted to swiftly flowing Dual-Phrase Distribution of Gas olid occasion.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail down.
Fig. 1 is the utility model overall structure and partial cutaway diagrammatic sketch.
Fig. 2 is the utility model overall structure and mounting point figure.
As shown in Figure 1, 2, mainly form with the valve body 11 that is placed in pneumatic 3 interior band seal ring by pneumatic 3.Pneumatic 3 of the utility model is by cylinder body 1 and be placed in piston 2 in the cylinder body 1, be located at the end cap 4 at cylinder body 1 two ends and two air inlet/outlets 5,6 of being located on the cylinder body 1 are formed, and is provided with two cavity volumes 7,8 in the cylinder body 1.The described piston 2 that is placed in the cylinder body 1 has two, and is placed on the same axle center 9.The centre of cylinder body 1 also is provided with gear shaft 10.
The utility model is mainly used in the Pneumatic ash conveying system, is specially adapted to swiftly flowing Dual-Phrase Distribution of Gas olid occasion.
