Abstract

The invention discloses a large diameter valve high temperature sealing test device. A gas storage tank is connected with an air compression station or an air compression pump through a first cut-off valve. A gas outlet end of the gas storage tank is connected with a surge tank in an electric heating room. A pressure test plate is disposed behind the surge tank. A valve under test is installed between the surge tank and the pressure test plate, and the surge tank, the pressure test plate and the valve under test are connected to form a cavity. The upper, lower, left, right, front and rear sides of the interior of the electric heating room are provided with electric heaters respectively. A second cut-off valve and a regulating valve are disposed on a gap pipe, and the second cut-off valve is located at the front of the regulating valve. A first security valve, a first pressure sensor and a first temperature sensor are disposed on the gas storage tank. A second security valve, a second pressure sensor and a second temperature sensor are disposed on the surge tank. A relief valve is disposed on the pressure test plate. The valve under test is connected with a drive device driving the valve under test to open and close. The invention is reasonable in structure, and can improve the working reliability of the valve.
