Effectiveness of the board is mainly seizing the flexibility of the disc, sometimes also can be used as a manual close pressure, lever type relief valve is mainly depends on the utility of the lever and weight strength and office, but because the lever type safety valve size often greatly limit the scope to choose. Higher temperature when choosing safety Industrial Valves with radiator. The relief valve is called the overflow valve. Figure for a piston valve, valve core is a tablet. Q: office principle of the hydraulic safety valve a: relief valve discharge is the main parameter, the displacement depends on the opening of the calibre of the seat and disc height, by the open height is not the same, is divided into tiny qi type and whole qi type two kinds. Vote by the operating pressure relief valve selection of nominal pressure relief valve, a vote by the operating temperature of the relief Industrial Valves using temperature range, calculated by the relief valve spring constant pressure value of the voting or leverage constant pressure range, and then on the basis of the media on the relief valve material and structure, and then on the basis of the relief valve discharge volume to calculate the throat area of the relief valve. Additional and impulse type hydraulic valve, pilot operated relief valve, safety valve switch, security, decompression valve, such as static weight type relief valve. Spring loaded safety valve mainly depends on the effectiveness of spring strength and office, spring loaded relief Industrial Valves is closed and not closed, ordinary inflammable, explosive or toxic mediums should choose close type, steam or inert gas can choose not closed type, such as in the spring type safety valve with the board and the board. 。 The following general rules for hydraulic pressure relief valve selection. When the system pressure is more than a specified value, the relief valve (open, the system of a small group of gas discharged into the atmosphere, make the system pressure shall not exceed the allowed value, therefore guarantee system is not an accident because the pressure was too high. Principle and structure of office: relief valve in the system security to take care of utility. This way for several typical structures of the relief valve. All rev type refers to the opening height of the disc seat throat diameter of a quarter. Tiny qi type refers to the opening height of the disc seat throat diameter of 1/40 ~ l / 20. So far more from the relief valve spring type and Marine valve lever type two kinds big. Air pressure on the piston of A utility, confirmed by the spring force when pressure exceeds the TVC, the piston is A top, A small group of compressed air is discharged into the atmosphere through the valve port; When air pressure is lower than the TVC, spring driving the piston down, close the valve port. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
