Manufacturers Introduce You to Telescopic Butterfly Valves

The telescopic butterfly valve is a type of valve that uses a circular butterfly plate as the closing element and operates by rotating the valve rod to open, close, and regulate the fluid passage. It serves as a component for achieving pipeline system shutdown and flow control.

The operating principle of a telescopic butterfly valve involves using a circular butterfly plate as the operating part, which, as it rotates with the valve stem, opens, closes, and adjusts the fluid passage. The butterfly plate of a telescopic butterfly valve is mounted in the diameter direction of the pipeline.

Inside the cylindrical passage of the expandable butterfly valve body, the circular disk butterfly plate rotates around the axis, with an angle of rotation between 0° and 90°. When it reaches 90°, the valve is fully open.

The advantages of adjustable butterfly valves mainly include the following aspects:

 Lightweight:The telescopic butterfly valve is composed of elastic silicone material, with a lightweight overall design, making it easy to maintain and install.

  2. Simple StructureThe structure of the telescopic butterfly valve consists of an inner and outer frame, filled with rubber and other materials in between. The flow and direction are regulated through the "butterfly" structure formed by the inner and outer frames.

Easy maintenance with low costs.

 ‌ Sealed wellThe telescopic butterfly valve is made of silicone material, featuring excellent high-temperature resistance, corrosion resistance, and wear resistance. It boasts reliable sealing performance with almost no leakage.

  High Comfort LevelThe telescopic butterfly valve boasts significant expansion and telescopic capabilities, enabling automatic adjustment and adaptation to the deformation of pipelines due to temperature or pressure variations.

   5. Versatile Features:The adjustable butterfly valve not only features regulating and cutoff functions but also compensates for thermal expansion and contraction caused by pipeline temperature differences, making installation, replacement, and maintenance easier.

  6. Compact Size:The volume of the telescopic butterfly valve is only about 35% of that of similar products, making it easy to install and use.

  7. User-FriendlySingle-phase power supply, easy wiring, no oiling or inspection required, waterproof and rustproof, installable at any angle.

 8. Enhanced Safety EquipmentEquipped with dual limit stops, overheat protection, and overload protection, the full stroke time is adjustable, and features manual operation.

  3. Metallurgy Industry:For controlling the flow of gases and liquids, particularly in blast furnaces and steelmaking processes.

‌  4. Hydropower IndustryTo control water flow and pressure, ensuring the rational allocation of water resources and the safety of water supply.

   5. Power Plant:Flow control and regulation for cooling water systems, ensuring stability and efficiency in the heat exchange process.

  6. Water Treatment Industry:Used to regulate flow and control water levels, ensuring stability and efficiency in the processing process.

7. Food Industry:To control the flow of liquids, ensuring the sanitation and safety of the production process.

 8. Textile and Paper Industry:To regulate and control the flow of media, ensuring stability in the production process and quality of products.

  9. Power Industry:For controlling the flow of gases and liquids, particularly in power generation and transmission processes.

1. Water and Gas Pipeline SystemUsed to regulate flow and control the movement of media, ensuring system stability and safety.

The maintenance and care of telescopic butterfly valves primarily includes the following aspects:

 Regular inspections and cleaning:Regularly inspect the connections and seals of butterfly valves for proper functioning, clean out debris and dirt inside the valves, ensuring smooth and normal operation of their opening and closing.

Wipe the valve surface with a soft cloth, avoiding the use of hard objects to scratch to prevent damaging the valve surface.

  2. Seal Performance InspectionRegular inspections of butterfly valve sealing performance can be conducted through methods such as inflation tests and hydrostatic tests. If leakage is detected,

It is essential to replace the seals promptly.

  3. Replacement of Vulnerable PartsRegularly inspect the vulnerable parts of butterfly valves, such as the valve plate and valve rod, and promptly replace worn or damaged components to ensure the normal operation of the valve.

 4. Anti-corrosion treatment:Corrosion protection for butterfly valves can be achieved through methods such as applying rust-proof paint coatings or spraying with corrosion-resistant coatings, thereby extending their service life.

  5. Lubrication:When maintaining butterfly valves, use the dedicated lubricant to ensure their normal service life.

 6. Avoid Over-Opening and ClosingAvoid excessive opening and closing of the butterfly valve during use to prevent damage to the butterfly plate and sealing surface.

  7. Paint Treatment:Regular painting of butterfly valves is conducted to prevent corrosion and oxidation.
