Marine Self Closing Drain Valve
Marine self closing drain valve is a kind of safety valve that can be automatically closed, and can automatically open and release pressure when the system overpressure or overtemperature, so as to protect the safety of equipment and personnel. The key components include valve body, spring and gasket.
Overview
Installation Requirements of Marine self-closing Drain Valve
1. Installation Position
The installation position of self-closing relief valve should be at the highest point of the system, and should be easy to operate and maintain. When installing, it should ensure that the connection port of the relief valve and the system pipeline is on the same level, and should use gaskets to ensure that the valve is firmly installed and the pressure relief quickly.
2. Installation Form
According to the different installation forms, the installation of self-closing relief valve will be different. In the installation of straight pipe type self-closing relief valve, the installation should be determined according to the flow direction arrow of the valve, the arrow points to the direction of the release of steam. In the flange type self-closing relief valve installation, should be in accordance with the flange medium of the actual working pressure level selection of flange.
3. Safety Distance
To ensure that the installation of self-closing relief valve safe and reliable, need to retain a certain safety distance, the distance should be 2-3 times the pressure release distance, if a certain distance must be used within a certain distance of temperature-resistant protective casing. There are also some valves for which the safety distance is specified, such as the drilling pressure resistance test valve.
