Match With Butterfly Valve
According to different connection methods, electric butterfly valves can generally be divided into the most common electric wafer butterfly valves and electric flange butterfly valves. The sealing materials include soft seals (normal temperature and pressure) and hard seals (high temperature and high pressure). The working power supply usually includes: AC220V, AC380V, DC24V, the input signal includes 4~20mA 0~10v and other weak current signals. Finally, according to the control form, it is divided into on-off type and regulating type. The on-off type plays the role of switch; the regulating type is used to adjust the flow and can accurately It is also a relatively expensive valve to adjust the flow to a thousandth of a degree.
Rubber Lined Butterfly Valve
The rubber lining in the rubber-lined butterfly valve uses high temperature to vulcanize the rubber and the valve body into one body. It has very high anti-corrosion properties and is generally used to control some corrosive fluids with strong acid and alkali properties. The sealing materials in rubber-lined butterfly valves include: hard rubber NR applicable temperature: -10℃~85℃, soft rubber BR applicable temperature: -10℃~85℃, butyl rubber IIR applicable temperature: -10℃~120℃, chlorine Applicable temperature of butadiene CR: -10℃~105℃;
The Difference Between Fully Lined Butterfly Valve And Semi Lined Butterfly Valve
1. Semi-lined butterfly valve means: the butterfly valve is not lined with rubber, but the connection between the butterfly valve and the valve body is lined with rubber; 2. Fully lined butterfly valve means: the butterfly plate of the butterfly valve and the parts connected to the valve body are lined with rubber.
The electric butterfly valve uses electric energy as the driving force. The electric device drives the valve stem, causing the butterfly plate to rotate 90° to open and close the valve. It can also receive 4~20mA or other signals from the industrial automation control system to accurately control the valve opening. , thereby achieving the regulation and control of different process parameters such as flow, temperature, and pressure.
Pre-installation instructions for wafer butterfly valve
1. Before installation and operation, use air spray to remove foreign objects on the piping, and clean the inside of the piping with clean water.
2. Carefully check whether the valve usage is consistent with its performance specifications; (temperature, pressure)
3. Check whether there are any debris in the valve channel and sealing surface, and remove them in time;
4. The valve must be installed promptly after unpacking, and please do not loosen any fastening screws or nuts on the valve at will; 5. Wafer-type butterfly valves must use special butterfly valve flanges.
6. The electric butterfly valve can be installed on the pipeline at any angle. For the convenience of maintenance, it is recommended not to install it upside down.
7. When installing the butterfly valve flange, you must ensure that the flange surface and the sealing rubber are aligned, the screws are tightened evenly, and the sealing surface must fit completely; if the screws are tightened unevenly, rubber bulges will appear to block the butterfly plate, or top the butterfly plate. Seizing the butterfly plate causes leakage at the valve stem.
Parts Introduction
Butterfly Valve Installation And Maintenance
1. During installation, the valve disc should stop in the closed position.
2. The opening position should be determined according to the rotation angle of the butterfly plate.
3. For butterfly valves with a bypass valve, the bypass valve should be opened before opening.
4. Installation should be carried out according to the manufacturer's installation instructions. Butterfly valves with heavy weight should be installed on a solid foundation.
