Stainless steel spring automatic reset ball valve, also known as spring automatic return ball valve or spring automatic closing ball valve, is a device that adds a spring handle on the basis of a ball valve. Its main working principle is to achieve automatic opening and closing of the valve through the compression and rebound of the spring. When the handle is rotated to open the valve, the spring is compressed; After releasing the handle, the spring will push the handle to close, thereby achieving the automatic reset function
Structural characteristics
The structural design of the stainless steel spring automatic reset ball valve is reasonable and aesthetically pleasing. The valve body adopts advanced casting technology, and the valve seat adopts an elastic sealing structure to ensure reliable sealing. The valve stem adopts a bottom mounted structure with reverse sealing function to prevent the valve stem from being flushed out when the valve chamber is abnormally pressurized. In addition, the valve has a simple structure, small size, light weight, easy operation, and is suitable for various working conditions
Application scenarios
Stainless steel spring automatic reset ball valves are widely used in industries such as petroleum, chemical, urban water supply and drainage, food, pharmaceuticals, and environmental protection. Its advantages include low fluid resistance, easy operation, simple maintenance, safety and reliability, etc
2. Especially in working conditions that require strict cutting off of the medium, this type of valve can significantly reduce manual operation, avoid medium loss and operational errors
