Abstract
The utility model relates to an eccentric butterfly valve, which consists of a valve body, a valve rod, a valve plate and a metal wave-shaped interlayer sealing ring. The utility model is characterized in that: the valve rod of the central line of the eccentric valve body is sleeved with the valve plate of the metal wave-shaped interlayer sealing ring. The utility model is of a proper design and good sealing property, and the structure of metal wave-shaped ring wave saw teeth wave form of the metal wave-shaped interlayer sealing ring enhances the performance of multi layers compound sealing ring, and the utility model solves that: the soft material like tetrafluoride used for valve sealing is likely to produce the phenomenon of expansion because of heat and flowing because of cold. The valve has a long service life which is agile for operation.
Description
The utility model relates to a kind of eccentric-butterfly-valve, relates to a kind of pipeline fluid is controlled, brisk valve of operation specifically.
At present, be applied to the substantial market of control flows body medium valve in the industrial pipeline, to satisfy the control needs of gaseous fluid, and existing the elephant with in the valve of the such flexible material of tetrafluoro as sealing, because the variation of its structural reason and serviceability temperature, the heat that the causes seal ring cold flow distortion of rising is torn, cause the valve plate and the abnormal sealing of valve seat of valve, generation is leaked and is scrapped too early, causes valve short working life, has a strong impact on normal industrial production and people's quality of life.
It is sealing material that the purpose of this utility model is to design a kind of flexible material, and the eccentric-butterfly-valve of long service life is to overcome the deficiencies in the prior art.
The purpose of this utility model is achieved in that it mainly is made up of valve body (1), valve rod (2), valve plate (3), metal wave mode interlayer seal ring (4), pressure ring (5).The valve rod (2) of valve body center line one side of it is characterized in that setovering is gone up suit and is connected with valve plate (3), is furnished with metal wave mode interlayer seal ring on the valve plate (3), and is compressed by pressure ring (5).Its feature also is metal wave mode interlayer seal ring (4), and it is formed by soft seal ring (7) MULTILAYER COMPOSITE that the surface has the metal wave mode circle (6) of zigzag fashion wave formula to reinforce flexible material.
The utility model compared with prior art, and is reasonable in design, and good seal performance has better solved flexible material and torn problem for the cold flow of sealing, and long service life is operated brisk.
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing one is a structural representation of the present utility model;
Accompanying drawing two is for constituting the metal wave mode circle (6) and the soft seal ring (7) of metal wave mode interlayer seal ring (4).
Referring to accompanying drawing, the utility model is made up of valve body (1), valve rod (2), valve plate (3), metal wave mode interlayer seal ring (4), pressure ring (5).Metal wave mode interlayer seal ring (4) is reinforced by metal wave mode circle (6) that soft seal ring (7) is composited.And metal wave mode interlayer seal ring (4) is fitted on the valve plate (3).Compressed by pressure ring (5), it is upward affixed that valve plate (3) is sleeved on valve rod (2), and valve rod (2) biasing is passed and is actively socketed on valve body (1) center line one side, forms valve rod (2) to valve body (1) off-centre, and valve body (1) is provided with packing holder.During use, clockwise rotate valve rod (2), valve plate (3) rotates together, and the metal wave mode interlayer seal ring (4) that presses solidly on valve plate (3) compresses to valve body (1) upper valve base, reaches hermetically closing.Rotate counterclockwise valve rod (2), valve rod (2) is being with valve plate (3) to rotate, and the metal wave mode interlayer seal ring (4) on valve plate (3) is lifted off a seat and opened valve.
Claims (2)
1, a kind of eccentric-butterfly-valve it mainly contain: valve body (1), valve rod (2), valve plate (3), metal wave mode interlayer seal ring (4), pressure ring compositions such as (5); It is characterized in that setovering is set with valve plate (3) on the valve rod (2) of valve body center line one side, is furnished with metal wave mode interlayer seal ring (4) on the valve plate (3), and is pressed solidly by pressure ring (5).
2, eccentric-butterfly-valve according to claim 1, its feature also are described metal wave mode interlayer seal ring (4), and it is composited by metal wave mode circle (6) and soft seal ring (7).
