Description
Technical Field
The utility model relates to the technical field of valve devices, specifically be an anticorrosion stainless steel lining fluorine butterfly valve.
Background
At present, a fluorine-lined butterfly valve and a rubber-lined butterfly valve are widely applied to various fields of petroleum, chemical engineering, metallurgical hydropower and the like as a component for realizing the on-off and flow control of a pipeline system. In the known butterfly valve technology, the sealing form mostly adopts a sealing structure, and the sealing material is rubber, polytetrafluoroethylene and the like, and is not suitable for industries of high temperature resistance, high pressure resistance, corrosion resistance, abrasion resistance and the like due to the limitation of structural characteristics.
Although the existing valve can have a good sealing effect under a working condition environment with strong corrosive force, the driving function of the existing valve cannot have good corrosion resistance, so that the function is reduced or the function is failed due to the fact that the driving function is corroded under the condition that the sealing performance of a product is good and intact.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: in order to solve the problems, a stainless steel fluorine-lined butterfly valve for corrosion prevention is provided.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an anticorrosive stainless steel lining fluorine butterfly valve, includes valve body (1), butterfly plate (2) and drive assembly (7), its characterized in that, butterfly plate (2) are located inside valve body (1), valve body (1) upper end is equipped with packing groove (3), be equipped with upper seal filler (4) in packing groove (3), the cover is equipped with gland (5) on butterfly plate (2), valve body (1) upper end is equipped with support (6), support (6) are an organic whole in valve body (1), set up in support (6) upper end drive assembly (7), drive assembly (7) are fixed on support (6) through locking drive fastener (8).
As a further description of the above technical solution:
the whole driving assembly (7) is made of corrosion-resistant stainless steel.
As a further description of the above technical solution:
and shaft end sealing pairs (9) are arranged at the joints of the upper end and the lower end of the valve body (1) flow channel and the butterfly plate (2).
As a further description of the above technical solution:
