摘要： An excessive fluid pressure safety valve for a fluid processing heat exchanger transferring thermal energy to fluids in the heat exchanger by piping extending through the heat exchanger is formed by a valve, normally maintained open by a pressure responsive collapsible pin, interposed in the thermal energy conductor upstream from the heat exchanger. Fluid pressure above a predetermined value in a tube connecting the heat exchanger with the valve axially moves a piston in the valve toward and collapses the pin to close the valve.

摘要： An air pressure adjusting module compensating balancing valve and its chamber structure is disclosed. A dovetail-shaped rod perpendicular to a horizontal channel is provided at a connection. At the bottom face of the horizontal channel is provided with conic shaped rod parallel to the horizontal channel. The cross-section of the horizontal channel has a circular arch shaped lower end. The outlet of the horizontal channel is a recessed face. At the bottom of the section of the horizontal channel is provided with an overflow channel having a slanting face at the bottom face thereof. A dovetail-shaped partition is provided at the bottom face of the overflow channel to partition the overflow channel into two sides, such that the air into the inlet and flows out from the outlet will obtain a higher flow rate ratio and the pressure is stable as laminar flow.
