1.4529 boardDesulfurization butterfly valve/desulfurization denitrification butterfly valve/desulfurizationdenitrificationSlurry butterfly valve/flue gas desulfurization butterfly valveIt must meet several requirements such as corrosion, wear, flow rate, and temperature. All kinds of mineral fuels contain sulfur, especially coal, which generates a large amount of SO2 after combustion, seriously polluting the air. The most effective way to control pollution is flue gas desulfurization. Including China, the currently widely used wet desulfurization technology is "lime (limestone) - gypsum". In this process system, multiple corrosive media are involved and contain particulate materials, which cause strong corrosion and wear to the equipment. Therefore, there are special requirements for the material and structural form of the valve.

Material of parts:

Valve body: gray cast iron, ductile iron, carbon steel

Butterfly plate: Carbon steel coated with rubber, carbon steel coated with fluoroplastic, stainless steel, duplex stainless steel plate 1.4529, 2507 C276

Valve seat: natural rubber, EPDM rubber

Valve stem: stainless steel, 2Cr13, 304

Performance indicators:

Service life: The desulfurization butterfly valve can still ensure "no air leakage" when closed after more than 10000 uses.

Pressure drop: If the pressure drop is too large, it will increase energy consumption. However, it should be noted that valves are not the * factor causing pressure drop in pipeline systems, and there are also the following factors that can lead to pressure drop. The fluid cross-section of the pipeline. Friction force on the inner wall of the pipeline.

Changes in flow direction when passing through components. The fluid characteristics of desulfurization butterfly valves are three times or even higher than those of globe valves, and 75% of those of gate valves of the same size.

Universality: The desulfurization butterfly valve controls and regulates the pipeline system by opening, closing, and throttling balance. Compared with gate valves or globe valves, desulfurization butterfly valves have better "versatility". Due to the use of various surface treatment techniques and the selection of elastic material pipelines, desulfurization butterfly valves have excellent chemical corrosion resistance.

Product Introduction

In air pollution, sulfur dioxide is an important pollutant, and over 60% of sulfur dioxide pollutants come from industrial flue gas emissions. With the gradual improvement and enhancement of environmental standards in China, as well as the increasing awareness of the environment among the public, desulfurization treatment must be carried out for projects with industrial flue gas emissions in China in the future. One of the important components in flue gas desulfurization equipment is the valve, which is required to be able to withstand chloride, oxide, acid, as well as harsh abrasive wear and mud corrosion. The correct selection of valve materials and structural forms to extend the service life of the valve is the key to flue gas desulfurization butterfly valves.

A complete desulfurization system is needed in many industrial or power fields. At present, the limestone gypsum wet method and furnace tower desulfurization device are used, and the desulfurization efficiency of this desulfurization device can reach 95.5%. After passing through the desulfurization pipeline, the medium of the limestone slurry system will exhibit strong corrosiveness, which has strict requirements for the entire pipeline system, fluid control valves, and valve actuators. The desulfurization butterfly valve is designed and manufactured to meet the special requirements of the desulfurization system.

The desulfurization and denitrification butterfly valve is designed specifically for power plant desulfurization and denitrification projects, fully considering the corrosion and wear of the valve caused by desulfurization slurry, ensuring that the valve plate lining is a component that can come into contact with the slurry, while other components are not corroded by limestone (or lime paste) slurry. Therefore, the valve body and stem do not need to use expensive alloy (2205) materials, greatly saving costs. The valve seat design of the desulfurization butterfly valve separates the valve body from the fluid medium. Compared with other similar valves, it has a better way of securing the valve seat, quick on-site replacement of the valve seat, zero valve leakage, and low friction. The butterfly valve plate is made of high-performance alloy (2205) material, which effectively resists the corrosion and wear of the slurry.

Application scope:

The desulfurization butterfly valve can be widely used for regulating and intercepting fluid pipelines in hydropower, sewage, construction, air conditioning, petroleum, chemical, food, medicine, textile, papermaking, water supply and drainage, etc. It can also be adapted to different media such as water, gas, oil, etc. by changing the material, and is suitable for temperatures ranging from -20 to 80 ℃. By replacing the valve plate sealing ring, O-ring, butterfly plate, shaft and other materials, it can be applied to various media and different temperatures. The valve automatic control equipment is equipped with high-quality electric actuators or double acting pneumatic actuators, which can achieve both automatic and manual opening and closing functions.

Structural characteristics:

The main structure of the desulfurization butterfly valve consists of valve body, valve disc, valve seat, valve stem, and transmission operating mechanism. The valve seat adopts a detachable structure and can be made of materials that are resistant to high temperature, low temperature, corrosion, light, and aging according to the physical and chemical characteristics of different media.

The inner and outer surfaces of the valve ductile iron shell can be coated with high-temperature electrostatic spraying epoxy resin powder coating, which has high corrosion resistance and * bonding strength with the ductile iron substrate. The coating degree is 0.2-0.5mm

1. Adopting a medium linear structure without eccentricity design, it has significant characteristics of low operating torque, and the economy is significant when configuring electric devices;

2. Reasonable design, compact structure, easy installation and disassembly, and convenient maintenance;

3. Adopting a rubber lined structure, the butterfly plate's circular sealing surface is precision machined to a high degree of smoothness, resulting in an extremely low friction coefficient for the rubber valve seat and a long service life for the valve;

4. The flow characteristics of the valve plate sealing surface are linear, with a small flow resistance coefficient and low valve flow resistance;

5. The molded rubber valve seat designed has balance and support, effectively avoiding damage to the rubber caused by uneven force. When the valve is fully closed, the rubber is in a compressed state to maintain zero leakage;

6. The rubber sealing surfaces of the two ports of the valve protrude from the ductile iron flange surface, and no additional rubber sealing gaskets are required for valve installation in pipelines

7. The selection of the operating mechanism for butterfly valves is flexible;

8. The butterfly valve has a beautiful appearance and good corrosion resistance.
