The existing butterfly valve structure is a triple eccentric structure, and has the advantages that for example, a hard sealing structure is adopted, and a sealing surface is subjected to surfacing of temperature-resistant and corrosion-resistant alloy, so that the butterfly valve can be used in a high-temperature and high-pressure environment; secondly, when the valve is opened, the valve seat and the sealing surface of the butterfly plate are instantaneously separated, no friction exists between the valve seat and the sealing surface of the butterfly plate, so that the service life of the butterfly valve is prolonged, but the conventional butterfly valve with the triple eccentric structure also has problems in the use process, because the multi-layer soft and hard stacked sealing ring is fixed on the butterfly plate, when the valve plate is in a normally open state, the sealing surface of the butterfly plate is flushed positively by a medium, and after the soft sealing belt in the metal sheet interlayer is flushed, the sealing performance is influenced;
as shown in fig. 16, the rotation center of the butterfly plate 602 and the sealing line of the valve seat ring form a first eccentricity, the rotation center of the butterfly plate 602 and the center line of the valve body 601 form a second eccentricity, and the cone center line of the cone and the center line of the valve body 601 form a third eccentricity; the butterfly plate 602 forms an elliptical sealing surface when in contact with the valve seat ring and forms a multi-position seal between 86 and 94 degrees, enhancing the sealing effect.
The sealing principle is that the valve rod 608 is driven to rotate, the valve rod 608 drives the butterfly plate 602 to rotate through the positioning pin 610 so as to be in contact with a valve seat ring on the valve body 601, and sealing specific pressure is generated through the elasticity of the valve seat ring, so that a sealing effect is achieved, and the butterfly valve rotates clockwise to be in a closing direction and rotates anticlockwise to be in an opening direction;
As shown in FIG. 17, the valve seat adopts a floating design, the valve seat is in a right circular ring before the butterfly plate is closed, and when the butterfly plate is closed, the valve seat is pressed into close contact with the butterfly plate along with gradual pressing of the butterfly plate to move in a sealing way, two sides of the valve seat are expanded, and the valve seat is tensioned up and down; when the butterfly plate is completely closed, the valve seat is an elliptical ring and is tightly attached to the sealing surface, and the sealing is realized by utilizing the elasticity of the valve seat, so that the butterfly plate is elastic and can adapt to temperature and pressure changes in the working condition range;
as shown in fig. 18, stainless steel protection layers or other materials are welded at the contact parts of the valve seat sealing rings (valve seat rings 614), so that the working surfaces cannot be corroded by media in long-term use, normal operation of the valve is ensured, and the service life of the valve is prolonged.
The sealing structure of the butterfly valve is an all-metal elastic sealing structure, and is not influenced by the cold and hot expansion coefficients of the medium and the flowing direction of the medium; the valve seat ring of the butterfly valve adopts high-strength nickel-based alloy; the butterfly valve is sealed without adding redundant sealing parts, the bidirectional peer sealing is realized by means of the sealing of the valve seat ring, the sealing effect is good, the elastic sealing of pure metal to metal is realized through the unique triple eccentric sealing structure of the butterfly valve, the floating elastic U-shaped metal sealing ring enables the valve to realize bidirectional peer sealing through the elasticity of the valve, and meanwhile, the influence of the huge thermal stress of a heat supply pipeline on the valve sealing to produce the triple eccentric elastic metal sealing butterfly valve is overcome, and the butterfly valve has the advantages of small size, light weight, low cost and stable sealing performance.
The valve seat adopts a floating design, the valve seat is a right circular ring before the butterfly plate is closed, when the butterfly plate is closed, the valve seat is pressed into close contact with the butterfly plate along with gradual pressing of the butterfly plate to move in a sealing way, two sides of the valve seat are expanded, and the valve seat is tensioned up and down; when the butterfly plate is completely closed, the valve seat is an elliptical ring and is tightly attached to the sealing surface, and the sealing is realized by utilizing the elasticity of the valve seat, so that the butterfly plate is elastic and can adapt to temperature and pressure changes in the working condition range.
