Chevedave's first shutout of the season earned him the game's first star.
Brady Gaudet, Rob Trzonkowski and Colin Smith scored for the Blazers (3-0-1), who dropped a 4-3 shootout decision to the Royals on Friday.
Jared Rathjen made 36 saves in a losing effort for Victoria (3-0-1).
Neither club could score on the power play as they both finished the game 0-for-5 with the man advantage.
Gaudet opened the scoring for Kamloops with a long wrist shot from the left point through a screen.
Trzonkowski made it 2-0 early in the second after receiving a long stretch pass from linemate Aaron Macklin that sent him in alone for a back-hand deke.
The Blazers dominated the second period, outshooting the Royals 16-6.
A thunderous body check by Victoria defenseman Tyler Stahl, just back from a six-game suspension, ignited his team and the home crowd late in the period.
Despite a few good chances, however, the Royals couldn't solve Cheveldave in the final period.
The Blazers then went up 3-0 halfway through the third period when Smith banged in a rebound right on Rathjen's doorstep.
