Embodiment Construction

[0009] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0010] Wherein, the anti-oxidation alloy material used to seal the valve comprises the combination of the uppermost stellite alloy, the deoxidizer of the middle layer and the stainless acid-resistant steel of the lowermost layer, and the stellite alloy is cobalt chromium tungsten alloy, cobalt chromium molybdenum alloy or cobalt based alloy , the Stellite alloy accounts for 74%-76% of the overall weight of the anti-oxidation alloy material used for sealing valves, and the described deoxidizer accounts for 3%-5% of the overall weight of the anti-oxidation alloy material used for sealing valves, so The above-mentioned stainless and acid-resistant steel accounts for 20%-22% of the total weight of t...

Abstract

The invention discloses an antioxidant alloy material for sealing a valve. The antioxidant alloy material for sealing the valve is formed by combining stellite arranged on the uppermost layer, a deoxidizing agent arranged on the middle layer and stainless acid-resisting steel arranged on the bottommost layer; the stellite is cobalt-chromium-tungsten alloy or Co-Cr-Mo alloy or cobalt-base alloy, the stellite accounts for 74%-76% of the total weight of the antioxidant alloy material for sealing the valve, the deoxiding agent accounts for 3%-5% of the total weight of the antioxidant alloy material for sealing the valve, and the stainless acid-resisting steel accounts for 20%-22% of the total weight of the antioxidant alloy material for sealing the valve. The antioxidant alloy material for sealing the valve has the advantages of corrosion resistance, scratch resistance, erosion resistance and oxidation resistance.

Description

technical field [0001] The invention relates to an anti-oxidation alloy material used for sealing valves. Background technique [0002] Because the valve has a wide range of uses, it plays a very important role. For example: in power plants, valves can control the operation of boilers and steam turbines; in petroleum and chemical production, valves also play a role in controlling the normal operation of all production equipment and technological processes. The same is true in other sectors. Nevertheless, comparisons of valves with other products are often overlooked. For example: When installing machinery and equipment, people often focus on the main machinery and equipment, but ignore the valves. This will reduce the overall production efficiency or stop production, or cause various other accidents to occur. Therefore, serious and responsible work must be carried out on the selection, installation and use of valves. [0003] The electric drive valve is a commonly used ...
