Description
Technical field
The utility model relates to a kind of valve, and more particularly, it relates to a kind of butterfly valve.
Background technique
It is on valve interior wall, arrange one deck backing layer that lining fluorine butterfly valve is different from common butterfly valve, and backing layer adopts fluoroplastic making to have good corrosion resistance.Existing lining fluorine butterfly valve is due to its unreasonable structure, and valve seal is poor, cannot reach the zero leakage standard of valve in-vivo medium.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is the lining fluorine butterfly valve providing a kind of good seal performance rational in infrastructure.
For achieving the above object, the utility model provides following technological scheme: a kind of cascade zero leakage lining fluorine butterfly valve, comprise valve body, valve seat, butterfly plate and valve rod, valve rod to be fixedly connected with butterfly plate with valve seat through valve body, described valve seat is that fluoroplastic material makes, valve rod is made by stainless steel material and comprises upper valve rod and lower valve rod, described butterfly plate and valve-stem integrated are cast, described butterfly plate surface, lower valve rod surface and upper valve rod are all enclosed with fluoroplastic material by the one end connecting butterfly plate to the outer surface between the part contacted with valve body, the position that described upper valve rod is connected with valve seat is ladder shaft-like, the two ends that described butterfly plate is connecting upper valve rod and lower valve rod are provided with the column construction abutted against with valve seat, the end face that described upper valve rod is connected with valve body with lower valve rod is provided with axle sleeve, rigidity packing ring and resilient rubbber cushion.
Upper valve rod realizes the sealability with the reasonable interference fit improving product of valve seat by the structure of ladder shaft-like, the column construction abutted against with valve seat that butterfly plate is arranged at the two ends connecting upper valve rod and lower valve rod, add the area of contact of butterfly plate and the upper and lower both sides of valve seat, improve the sealability of valve seat and butterfly plate, the axle sleeve arranged, rigidity packing ring and resilient rubbber cushion improve the stability connected between valve rod and valve body all further, prevent it from loosening and cause leakage.
The utility model is set to further: be provided with elastic rubber strip between described valve seat and valve body.
By adopting technique scheme, preventing from occurring between valve seat and valve body loosening, ensure that the sealing of product.
The utility model is set to further: described axle sleeve is provided with interior O RunddichtringO and outer O RunddichtringO, and described interior O RunddichtringO and outer O RunddichtringO are along stem shaft to being arranged alternately.
By adopting technique scheme, make the process connecting valve rod and valve body during installation convenient, interior O RunddichtringO and outer O RunddichtringO are to valve rod and axle sleeve, play good sealing effect respectively between axle sleeve and valve body, and interior O RunddichtringO and outer O RunddichtringO can replace the interchangeability using and improve product parts.
