Abstract

The invention relates to a valve for a cross pipe pressurized reactor and aims at providing the valve for the cross pipe pressurized reactor, which can perform loading and unloading on the pressurized reactor under normal operation conditions. The valve comprises a valve casing (1), a ball valve (2) and a ball valve rod (3). Liquid inlet and outlet channels (4) which are mutually communicated in the same straight line are arranged inside the valve casing, the top of the valve casing is provided with a valve casing top cover (5); one end of the ball valve rod is connected with a groove at the upper end of the ball valve after penetrating the valve casing top cover; a valve body (11) is arranged between the ball valve and the valve casing, the upper end of the valve body is fixedly provided with a valve body rod (12), and the valve body rod is provided with a worm wheel (9) and a worm (10); the upper end of the ball valve rod is hinged to a linkage rod (27); the side wall of the valve casing is provided with a reloading window (28).

Description

Technical field [0001] The present invention relates to a valve, in particular to a valve used in a cross-tube pressure reactor. Background technique [0002] The way mankind excessively consumes primary energy to develop the economy must change. In the next 40 years, safe, clean, efficient, and reliable nuclear power installations will enter a period of rapid development, and nuclear power installations for ships with a reactor power of 60,000 kilowatts and above will receive increasing attention. [0003] The heavy water reactor is one of the four mainstream reactor types currently in use, and its commercial value is continuously increasing. The heavy water reactor has the advantages of online filling and unloading of fuel uranium, real-time detection and control of each tube reactor, etc., and its inherent safety has been recognized by the public. However, in the prior art, especially in cross-tube pressure reactors, it is impossible to perform online filling and unloading ope...
