Zusammenfassung:	An ultrahigh-voltage direct-current power transmission valve cooling system using a canned pump. An inlet of a main circulation pump (1), a three-way valve (2), an air heat exchanger (3), a main filter (4), a converter valve inlet flow meter (5), a converter valve inlet regulation valve (6), a thyristor converter valve (7), a converter valve outlet regulation valve (8), a converter valve outlet flow meter (9), and an outlet of the main circulation pump (1) are connected in sequence by means of pipelines to form a main circulation loop. A third end of the three-way valve (2) is connected to an inlet of the main filter (4). The main circulation pump (1) comprises a first canned pump (1-1) and a second canned pump (1-2) which are connected in parallel. A heating and degassing tank (14) is connected to the inlet of the main circulation pump (1). According to the valve cooling system, the heat load change of the thyristor converter valve can be tracked by means of water cooling capacity, so that the temperature of
