Intelligent adjustable flange electric soft seal butterfly valve

1Intelligent adjustable flange electric soft seal butterfly valveValve Introduction:

The structure is simple, the volume is small, and the weight is light, consisting of only a few parts. And it can be quickly opened and closed by simply rotating 90 °, with simple operation, and the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the resistance of the medium flowing through the valve body, so the pressure drop generated by this valve is very small, which has good flow control characteristics. Butterfly valves have two sealing types: elastic sealing and metal sealing. Elastic sealing valve, the sealing ring can be embedded on the valve body or attached around the butterfly plate. The dual-purpose soft sealed electric butterfly valve is composed of a rubber sealed butterfly valve and a carbon steel or stainless steel valve plate and stem. The electric fully lined rubber butterfly valve is suitable for regulating flow and intercepting media in water supply and drainage, gas pipelines with temperatures ≤ 80-120 ℃, such as food, medicine, chemical, petroleum, power, textile, papermaking, etc.

IIThe characteristics of the intelligent adjustable flange electric soft seal butterfly valve are:

1. Compact and lightweight, easy to disassemble and repair, and can be installed in any position.

2. The structure is simple and compact, with low operating torque and quick opening of 90 ° rotation.

3. The flow characteristics tend towards a straight line, with good regulation performance.

4. The connection between the butterfly plate and the valve stem adopts a pin free structure, which overcomes the possible internal leakage points.

5. The outer circle of the butterfly plate adopts a spherical shape, which improves the sealing performance and extends the service life of the valve. It can be opened and closed under pressure for more than 50000 times and still maintain zero leakage.

6. The sealing components are replaceable and the sealing is reliable, achieving bidirectional sealing.

7. Butterfly plates can be coated with coatings such as nylon or polytetrafluoroethylene according to user requirements.

8. This valve can be designed for flange connection and clamp connection.

9. The driving mode can be selected as manual, electric or pneumatic.

Electric flange butterfly valves are suitable for industries such as water supply and drainage, sewage, food, heating, gas, ships, hydropower, metallurgy, energy systems, and textiles, with temperatures ≤ 120 ℃ or ≤ 150 ° C and nominal pressures ≤ 1.6MPa. They are particularly suitable for bi-directional sealing and valve body corrosion prone applications, as a medium for regulating flow and intercepting flow.

3、 Safety precautions for pressure testing:

1. During the testing of electric valves, special attention should be paid to the personal safety of participants, who must wear safety shoes and helmets correctly. Strictly follow the experimental procedures.

2. During the electric valve testing process, it is important to take good care of the electric valve and its accessories.

3. The main purpose of electric valve calibration is to adjust the strength and sealing performance of electric valves. Strength performance: The strength performance of electric valves refers to the ability of electric valves to withstand media. Sealing performance: The sealing performance of electric valves refers to the ability of sealing parts at various locations to prevent media leakage. It is an important indicator of electric valves. There are three sealing parts of electric valves:

1) The contact area between the sealing surfaces of the opening and closing components and the valve seat (internal leakage, also known as poor sealing, will affect the ability of the electric valve to cut off the medium);

2) The fitting between the packing and the valve stem and packing box.

3) The connection between the valve body and the valve cover (leakage).
