Pulse Safety Valve
The pulse-type safety valve designed by Dazhong Valve Group is a cooperative brand of YOY. The safety valve of Yongyi Valve Group is composed of two parts: the main valve and the auxiliary valve. The pressure of the valve disc is stabilized by a lever and a heavy hammer, so that the valve can be sealed and moved. position and change the weight of the weight to achieve the required take-off pressure. The sealing surface is made of iron-based chromium-nickel stainless steel surfacing, the valve disc is heat-treated, and the upper part of the valve is provided with an electromagnet for opening and closing, so that the mechanical and electrical actions do not interfere with each other.
The pulse safety valve consists of a main valve and an auxiliary valve.
Also known as pilot-operated or combined auxiliary valve, it is a set of heavy-hammer lever-type or spring-type loading mechanism. When the pressure in the equipment exceeds the specified value, the auxiliary valve will act first, but it will not be directly exhausted. Instead, the auxiliary valve is used to pulse the Ren valve to drive the main valve to act and relieve pressure. The valve has flexible action, small opening and closing delay, and tight closing. Second, due to the complex structure, it has only been used for safety relief. Boilers and pressure vessels.
Use the lever and the weight to stabilize the pressure of the valve disc, so that the valve can be sealed, move the position of the weight and change the weight of the weight to achieve the required take-off pressure.
The sealing surface is made of iron-based chromium-nickel stainless steel surfacing, and the valve disc is heat-treated to improve wear resistance and erosion resistance.
The upper part of the valve has an electromagnet for opening and closing, and the mechanical and electrical actions do not interfere with each other.
