  • Pressure relief valve
    Patent number: 11193603
    Abstract: A pressure relief valve with a trigger mechanism having a plurality of tines on the ejector which engage with a fixed stop. The tine ends and/or the fixed stop are chamfered. The valve opens when the force from the contained fluid exceeds the force of the spring plus the force necessary to move the tines out of alignment with the fixed stop. The trigger pressure of the valve can be adjusted by adjusting the geometry of the tines. This is accomplished by using interchangeable tine sections on the ejector. Pressure is contained by a primary seal located on the outer diameter of the ejector.

  • Multi-outlet channel combination gas valve
    Patent number: 11175037
    Abstract: A multi-outlet channel combination gas valve includes a valve body, a solenoid valve and a flow regulating mechanism. The valve body has a multiple of air outlets, at least two outlet channels formed between each air outlet and an air inlet of the valve body, a regulating port disposed in the at least two outlet channels, and the flow regulating mechanism can regulate the gas flow passing through each regulating port of the valve body at the same time, and a solenoid valve with a dual-coil electromagnet structure. When the valve is opened, a relatively larger current is passed, and then a very small current will be provided thereafter to maintain an operation by low power consumption. Therefore, this gas valve can be used without a mains power, and a low-level regulating structure is provided for presetting a low-level flow of each air outlet.
