Abstract
The utility model provides a titanium, zirconium material check valve, comprising a valve body and a valve cover connected with the valve body, wherein, valve flaps are in sealing match with the valve body, a lining plate which is made of titanium materials or zirconium materials and completely covers and seals an opening of the upper end of the valve body is arranged between the valve cover and the valve body, forming the separation structure of the valve cover and the medium. The utility model applies the lining plate made of titanium materials or zirconium materials to completely separate the strong oxidation erosion media from the valve cover, and therefore the valve cover only needs to have the common erosion proof capabilities of preventing the erosion of water and air, etc.; the valve cover can be made of stainless steels. etc., which contributes to saving a great deal of titanium materials and zirconium materials and greatly lowering cost, along with reasonable structure and convenient manufacture.
Description
Technical field: the utility model relates to a kind of safety check 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 safety check, valve body, flap 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 safety check with material.
The utility model comprises valve body and connects valve gap on it, and flap then cooperates with valve seal, is lined with the liner plate of titanium material or zirconium material system between valve gap and valve body, and this liner plate hides the upper end open of closed valve fully, constitutes valve gap and dielectric isolation structure.
The utility model utilizes the liner plate 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 stainless steel etc., 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 4 of flaps and valve body 2 are sealed and matched.Be lined with the liner plate 3 of titanium material or zirconium material system between valve gap 1 and valve body 2, this liner plate 3 hides the upper end open of closed valve 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 liner plate 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 valve is significantly improved between the flap 4 of present embodiment and the valve body 2, satisfy the harsh operating mode of high temperature strong corrosion medium, as usage requirements such as dewatered melted type caustic soda.
Claims (2)
1. a titanium, zirconium material safety check, comprise valve body and connect valve gap on it, flap then cooperates with valve seal, it is characterized by: the liner plate (3) that between valve gap (1) and valve body (2), is lined with titanium material or zirconium material system, this liner plate (3) 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 safety check is characterized by: between flap (4) and the valve body (2) for being sealed and matched firmly.
