Abstract
The utility model relates to the technical field of valves, in particular to a novel forging steel double-sealing dish valve, which is characterized in that the novel forging steel double-sealing dish valve comprises a valve body, a dish plate, a sealing ring, a valve rod and a boundary grinding cover, wherein the boundary grinding cover is embedded on the valve body or the dish plate, the boundary grinding cover which is embedded on the valve body or the dish plate is made from high manganese wear-resistant steel, and a formed sealing pair is a metal sealing structure. The novel forging steel double-sealing dish valve has the beneficial effects that the novel forging steel double-sealing dish valve has excellent sealing performance, has the characteristics of high temperature resistance, high pressure resistance, corrosion resistance and long life and the like, and the operation saves labor, and is flexible and reliable.
Description
[technical field]
The utility model relates to valve technology field, especially a kind of novel forged steel double-sealing dish valve.
[background technique]
Gasket seal in traditional hard seal butterfly valve generally adopts Graphite pad or asbestos washer, behind the valve closing, reaches sealing effect by the extruding force between the sealing pair; When working pressure when 4.0MPa is above, very easily cause the damage of seal ring itself.The highest bearing capacity of these two kinds of pads is generally 2.5MPa, and heatproof only reaches 420 ℃ and is only applicable to the low-temp low-pressure occasion.
[summary of the invention]
A kind of novel forged steel double-sealing dish valve, it is characterized in that comprising valve body, butterfly plate, seal ring, valve rod and attached mill front cover, described attached mill front cover is embedded on valve body or the butterfly plate, the described attached mill front cover that is embedded on valve body or the butterfly plate, adopt high manganese wear-resistant steel to make, formed sealing pair is a shape metallic leak-proof structure.
Beneficial effect of the present invention: be embedded in the attached mill front cover on valve body or the butterfly plate, possess excellent sealing performance, have high temperature resistant, high pressure, characteristics such as anticorrosive, life-span is long, rapid operation, flexibility and reliability.Can be widely used on the pipe-line system of industries such as metallurgy, petrochemical industry, thermoelectricity and heating power, that makes fluid blocks and regulates usefulness.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Referring to Fig. 1, the 1st, valve body, the 2nd, butterfly plate, the 3rd, valve rod, the 4th, seal ring, the 5th, attached mill front cover.
[embodiment]
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
With reference to Fig. 1, a kind of novel forged steel double-sealing dish valve, it comprises valve body 1, butterfly plate 2, valve rod 3, seal ring 4, attached mill front cover 5.Attached mill front cover 5 adopts high manganese wear-resistant steel to make, and attached mill front cover 5 is embedded on valve body 1 or the butterfly plate 2, and formed sealing pair is metallic seal, and when high-temperature high-pressure medium passed through, its structure made to regulate and block medium with seal ring 4.
