Abstract
The utility model relates to an oblique axis and plate type metallic hard sealing butterfly valve, which is composed of a driving device, a thermal insulation seat, a valve body, a butterfly plate, a long axis, a minor axis, a sealing ring, a pressing ring, a right cylinder hole sleeve, an axis sleeve, a end cover, male pins, etc. The sealing ring is arranged on the butterfly plate to cause the long axis, the minor axis and the sealing ring to be inclined into a certain angle. When the butterfly valve is closed, the driving device drives the long axis to rotate, and the butterfly plate and the minor axis rotate following the long axis. Therefore, the sealing ring is contacted with the inner wall of the right cylinder hole sleeve, and is closed tighter and tighter, and thereby, the utility model achieves excellent sealing effect. The utility model has the advantages of good sealing performance, small flow resistance coefficient, energy saving, simple structure, heat resistance, high pressure resistance, good manufacturing process, easy assemblage, convenient maintenance, low manufacture cost and long service life. The utility model can take the place of import products.
Description
The utility model relates to a kind of metal hard-sealing butterfly valve, and the spy means a kind of inclined shaft, sheetmetal hard seal butterfly valve, and it is applicable in the pipeline of thermoelectricity plant, metallurgy, district heating system etc., opens, ends, regulates flow when making conveyance fluid and use.
In the prior art,,, make relatively difficulty because of the butterfly plate end is asymmetric arc as the patent No. 88212280.0 wafer type metal hard-sealing butterfly valves that our factory is produced, and can only one-way sealing, sealing effect is not ideal enough.
The purpose of this utility model is to overcome the prior art deficiency and a kind of inclined shaft, panel metal hard seal butterfly valve is provided.
Solution of the present utility model is: seal ring is contained on the butterfly plate, major axis, minor axis and seal ring three are tilted at an angle, when butterfly valve cuts out, the rotation of drive unit drive major axis, butterfly plate, minor axis rotate thereupon, thereby seal ring is contacted at straight cylinder borehole jack inwall, and the pass is tight more more, thereby reach good sealing effect.
Below in conjunction with accompanying drawing concrete structure of the present utility model is elaborated.
Accompanying drawing 1 is a main pseudosection of the present utility model.
Referring to accompanying drawing 1, the utility model is made up of drive unit (1), heat-insulating base (2), valve body (3), butterfly plate (4), seal ring (5), major axis (6), minor axis (7), trim ring (8), straight cylinder borehole jack (9), axle sleeve (10), end cap (11), pin (12).Major axis (6) one ends connect by heat-insulating base (2) and drive unit (1), the other end is gone up pack into the inclined hole of butterfly plate (4) projection of an axle sleeve (10) in the hole by valve body (3), minor axis (7) one ends are packed in the axle sleeve (10) of valve body (3), major axis (6), minor axis (7) and seal ring (5) three are inclined to the angle less than 18 °, its outer cap is equipped with end cap (11), the other end is contained in the inclined hole of butterfly plate (4) projection, pack into major axis (6) in butterfly plate (4) inclined hole, minor axis (7) is fixing with pin (12), butterfly plate (4) exterior edge face is circular, two steps are arranged on the exterior edge face, hollow tubular style (the O type that is welded, the C type) seal ring (5) is contained on the big footpath step of butterfly plate (4), trim ring (8) is contained on the path step of butterfly plate (4), valve body (3) internal diameter central authorities have a groove, right cylindrical cover (9) is welded in the groove, and the external diameter of seal ring (5) is greater than the internal diameter of straight cylinder hole shape cover (9).
Working principle of the present utility model is: when closing butterfly valve, drive unit (1) drives major axis (6) and rotates, make butterfly plate (4) simultaneously, minor axis (7) rotates thereupon, the seal ring (5) that then is contained on butterfly plate (4) the external diameter step contacts gradually with straight cylinder borehole jack (9) on valve body (3) inwall, and because major axis (5), minor axis (6) tilts at an angle with seal ring (5), seal ring (5) is inclined to very little angle with the normal cross section that valve body (3) is gone up straight cylinder borehole jack (9) endoporus (sealing surface), thereby make seal ring (5) pressurized symmetric deformation, and the pass is tight more more, reaches good sealing effect.When opened butterfly valve, rotate butterfly plate (4), be maximum open position during to 90 °.
The utility model compared with prior art, good seal performance, flow resistance coefficient is little, energy-conservation, Heatproof, resistance to pressure improve, and simple in structure, two way seal and anufacturability are good, easily Assembling, low cost of manufacture, easy to maintenance, long service life, alternative imported product.
Claims (1)
