Product Description
The centerline soft - sealed butterfly valve has a simple structure, with the valve stem axis located at the center of the valve body and the butterfly plate. It uses soft materials for sealing, featuring good sealing performance, rapid opening and closing, and low flow resistance. It is often used for on - off control of media in fields such as water supply and drainage, and gas supply.
Structural Design Features
1.Centerline Structure: The axis of the valve stem, the center of the butterfly plate, and the center of the valve body are all on the same axis. This design ensures that the butterfly plate is evenly stressed during the opening and closing process, rotates flexibly, reduces friction and wear, and extends the service life of the valve.
2.Soft - Sealing Design: Soft materials such as rubber and polytetrafluoroethylene (PTFE) are used as the sealing surface. They can tightly adhere to the butterfly plate and the valve seat, achieving excellent sealing effects and effectively preventing medium leakage.
3.Integral Cast Valve Body: Generally, an integral casting process is adopted. This gives the valve body good strength and rigidity, enabling it to withstand certain pressure and temperature variations, ensuring the stability of the valve under complex working conditions.
Functional Characteristics
1.Rapid Opening and Closing: It only takes a 90° rotation to complete the opening or closing operation. The operation is simple and fast, which can meet the requirements of some systems for opening and closing speed.
2.Good Regulation Performance: During the opening process of the butterfly plate, the medium flow rate can be precisely controlled by rotating the angle, realizing different degrees of flow regulation.
3.Reliable Sealing: The soft - sealing material has excellent elasticity and sealing performance. It can ensure zero leakage under low - to medium - pressure working conditions, making it suitable for occasions with high sealing requirements.
4.Low Flow Resistance: After the butterfly plate is opened, the cross - section of the passage is close to the inner diameter of the pipeline, allowing the medium to flow smoothly. The flow resistance coefficient is small, which can reduce energy consumption.
Application
1.Water Supply and Drainage Systems: It is used in urban water supply and sewage treatment pipelines to control the on - off of water flow and regulate the flow rate. Its good sealing performance can prevent water leakage and ensure the safety of water supply.
2.Heating, Ventilation, and Air Conditioning (HVAC) Systems: In heating, ventilation, and air - conditioning pipelines, it regulates the medium flow rate to achieve precise control of temperature and air volume, meeting the comfort requirements of different environments.
3.Gas Systems: It is suitable for urban gas transmission pipelines. With its reliable sealing performance, it ensures that gas does not leak, safeguarding people's lives and property.
4.Food and Pharmaceutical Industries: Soft - sealing materials and structural designs that meet hygiene standards are adopted. They meet the strict requirements of the food and pharmaceutical industries for medium purity and hygiene, and are used to transport various pharmaceutical liquids and food raw materials.
