Abstract
A titanium, zirconium gate valve comprises a valve cover, a valve body and a valve stem, wherein, a valve plate is connected with the lower end of the valve stem to closely match with the valve body; the valve stem is covered with a bush made of titanium or zirconium; corrosion resistant sealing packing is arranged between the upper part of the bush and the valve stem; the lower edge of the bush is positioned between the valve cover and the valve body, and an opening at the upper end of the valve body is completely covered by the bush, thereby forming an isolation structure between the valve cover and a medium. The utility model causes the strong oxidizing corrosive medium to be completely separated from the valve cover with the bush made of titanium or zirconium, and the valve cover just needs to be provided with general corrosive performance, such as resistance of water corrosion, air corrosion, etc., the valve cover can be made of stainless steel, etc., therefore, the utility model not only saves massive titanium and zirconium to reduce the cost greatly, but also has the advantages of reasonable structure and convenient manufacture.
Description
Technical field:
The utility model relates to a kind of gate valve of powerful oxidation corrosion resistance corrosion.
Background technique:
In fields such as petrochemical industry, soda acid, chlorine and desalination of sea water, owing to often need the strong oxide etch medium of line transportation, adopt the corrosion resistant valve of common stainless steel material can not reach the usage requirement of corrosion resistant fully, but will use just powerful oxidation corrosion resistance corrosivity of special noble metal manufacturing such as titanium material, zirconium material.The valve gap of general titanium, zirconium material gate valve, valve body, flashboard, valve rod etc. all use titanium material or zirconium material, and the material of use is many, and particularly valve gap and valve body materials are most of, and cost is very high, is unfavorable for promoting.
Summary of the invention:
At the deficiencies in the prior art, it is a kind of rational in infrastructure that the utility model provides, and saves special titanium, zirconium material gate valve with material.
The utility model comprises valve gap, valve body and valve rod, flashboard is connected the valve rod lower end and valve seal cooperates, on valve rod, be with the lining of titanium material or zirconium material system, between lining top and valve rod, be provided with the corrosion resistant stuffing box packing, the lower edge of this lining is then between valve gap and valve body, and hide the upper end open of closed valve fully, constitute valve gap and dielectric isolation structure.
The utility model utilizes the lining of titanium material or zirconium material system that strong oxide etch medium and valve gap are separated fully, valve gap only need have the common corrosion resistant performance of corrosion such as preventing moisture, air to get final product, the valve gap manufactured materials can use materials such as stainless steel, a large amount of titaniums, zirconium material have not only been saved, cost is declined to a great extent, and it is rational in infrastructure, easily manufactured.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings:
Accompanying drawing is embodiment's a main structure schematic representation.
Embodiment: as shown in the figure, valve gap 1 is connected valve body 2 tops, and flashboard 5 is connected valve rod 4 lower ends and valve body 2 is sealed and matched.On valve rod 4, be with the lining 3 of titanium material or zirconium material system, between lining 3 tops and valve rod 4, be provided with corrosion resistant stuffing box packing 6, the lower edge of this lining 3 and hides the upper end open of closed valve 2 then between valve gap 1 and valve body 2 fully, constitutes valve gap and dielectric isolation structure.To the flow through strong oxide etch medium of valve body 2 inner chambers of this lining 3 blocks, and can not produce with valve gap 1 contact, and valve gap 1 can adopt made such as stainless steel like this, does not need titanium, zirconium material etc., and cost significantly reduces.
For being sealed and matched firmly, the serviceability temperature of gate valve is significantly improved between the flashboard 5 of present embodiment and the valve body 2, satisfy the usage requirement of operating modes such as high temperature strong corrosion medium.
Claims (2)
1. a titanium, zirconium material gate valve, comprise valve gap, valve body and valve rod, flashboard is connected the valve rod lower end and valve seal cooperates, it is characterized by: the lining (3) that on valve rod (4), is with titanium material or zirconium material system, between lining (3) top and valve rod (4), be provided with corrosion resistant stuffing box packing (6), the lower edge of this lining (3) then is positioned between valve gap (1) and the valve body (2), and hides the upper end open of closed valve (2) fully, constitutes valve gap and dielectric isolation structure.
2. titanium according to claim 1, zirconium material gate valve is characterized by: between flashboard (5) and the valve body (2) for being sealed and matched firmly.
