Abstract
The utility model relates to a metal tight sealing butterfly gate with an inclined axle, which comprises a driving device, a heat insulation seat, a valve body, a butterfly plate, a long axle, a short axle, a sealing ring, a pressing ring, a straight cylindrical sleeve, an axle sleeve, an end cover, a male pin, etc. The sealing ring is arranged on the butterfly plate to enable the long axle, the short axle and the butterfly plate to be inclined with a certain angle. When the butterfly valve is closed, the driving device drives the long axle to rotate with the rotation of the butterfly plate and the short axle in order to enable the sealing ring to contact with the straight cylindrical sleeve on the inner wall of the valve body to be further tightened with closing in order to obtain excellent sealing effect. The utility model has good sealing performance, small flow resistance coefficient, energy saving, simple structure, temperature resistance, pressure resistance increase, good manufacturability, easy assembly, convenient maintenance, low manufacture cost and long service life and can replace the imported products.
Description
The utility model relates to a kind of metal hard-sealing butterfly valve, and the spy means a kind of clino-axis type metal hard-sealing 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, be 882122800 wafer type metal hard-sealing butterfly valves as the patent No. of our factory production, because of the butterfly plate end face is asymmetric arc, make relatively difficulty, and can only one-way sealing, sealing effect is not ideal enough.
The purpose of this utility model is to overcome the deficiency of prior art and a kind of clino-axis type metal hard-sealing butterfly valve is provided.
Solution of the present utility model is: seal ring is contained on the butterfly plate, major axis, minor axis and butterfly plate three are tilted at an angle, when butterfly valve cuts out, drive unit drives major axis and rotates, butterfly plate, minor axis rotate thereupon, thereby the right cylindrical cover that makes seal ring and valve interior wall contacts and the pass is tight more more, thereby reaches 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 by drive unit (1), heat-insulating base (2), and valve body (3), butterfly plate (4), seal ring (5), major axis (6), minor axis (7), trim ring (8), straight garden cylindrical sleeve (9), axle sleeve (10), end cap (11), pin (12) is formed.Major axis (6) one ends connect by heat-insulating base (2) and drive unit (1), the other end is packed into by the last inclined hole internal axle sleeve (10) of valve body (3) in butterfly plate (4) the protrusion inclined hole partly, minor axis (7) one ends are packed in the inclined hole axle sleeve (10) of valve body (3), its outer cap is equipped with end cap (11), the other end is contained in butterfly plate (4) and protrudes in the inclined hole partly, 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, 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, straight garden bolster kit (9) is welded in the groove, and the external diameter of seal ring (5) is greater than the external diameter of butterfly plate (4) and the internal diameter of straight garden cylindrical sleeve (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 right cylindrical cover (9) on valve body (3) inwall, and since major axis (5), minor axis (6) tilt at an angle with butterfly plate (4), thereby make seal ring (7) 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 80 °.
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, anufacturability is good, easily dress Join, low cost of manufacture, easy to maintenance, long service life, alternative imported product.
