Design features of bolted bonnet connecting gate valve
The bolted bonnet connection gate valve is mainly composed of parts such as the valve body, bonnet, gate plate, valve stem, bolts and seals. The valve body and bonnet are connected by bolts to form a sealed integral structure. The bonnet is provided with a stuffing box for accommodating packing to prevent medium leakage. The valve stem is connected with the bonnet through the stuffing box to drive the gate plate to realize the opening and closing of the valve.The design of the bolted bonnet connection gate valve makes it maintain high reliability under various working conditions. The bolted connection structure is simple, easy to install and disassemble, and convenient for daily maintenance and overhaul. When it is necessary to replace seals or perform other maintenance operations, the bonnet can be easily disassembled by loosening the bolts without the need for complex tools or equipment.
Bolted bonnet connection gate valves can adapt to various working conditions, including high temperature, high pressure, and corrosive media. By choosing appropriate materials and seals, this type of valve can operate reliably within a wide range of temperatures and pressures. For example, in industries such as petroleum, chemical, and natural gas, bolted bonnet connection gate valves are widely used for the interruption and control of pipeline systems.
The bolted connection structure is simple and sturdy, capable of withstanding large pressures and temperature changes. This connection method ensures the sealing between the valve body and the bonnet through the preload of the bolts, and can maintain stable performance even during long-term operation. In addition, the design of bolted bonnet connection gate valves enables them to maintain good sealing performance under high pressure and high temperature conditions, reducing the risk of leakage.
The maintenance process of bolted bonnet connection gate valves is simple and quick. Due to its structural design, maintenance personnel can easily remove the bonnet, replace seals or perform other maintenance operations. This design not only reduces maintenance costs but also reduces downtime and improves the operating efficiency of the system.
