"It's up to us to keep in shape, so when we come back we're ready to go again," center Brayden Schenn said.
Emery, getting his first start in seven games, preserved the win with an outstanding save on rookie Sean Monahan as he redirected David Jones' right-wing pass in front with 1 minute, 30 seconds left.
"He's a winner; he's won everywhere he's been," Flyers coach Craig Berube said.
Schenn and Scott Hartnell each scored their 15th goals as the Flyers defeated a Calgary team that had won six of its previous seven games.
After a Calgary turnover, Claude Giroux picked up a loose puck and quickly fired a shot from the top of the right circle that deflected off Hartnell's skate and past Reto "Yogi" Berra, giving the Flyers a 2-0 lead with 15:56 left in the third period.
Giroux, bypassed by Team Canada for an Olympic spot, has 15 goals and 39 points in his last 31 games, and he leads the NHL in points since Dec. 11.
Calgary, which outshot the Flyers by a 25-12 margin over the last two periods, got to within 2-1 when Matt Stajan scored on a rebound with 2:26 remaining.
"It wasn't a pretty game, but we got the two points," defenseman Andrej Meszaros said.
Earlier, Schenn took a pass from Simmonds and fired a left-circle one-timer that appeared to deflect off Berra's shoulder before going into the net with 11:56 left in the second period. Vinny Lecavalier set a screen in front, helping Schenn score just his second goal in the last 11 games.
"There's always ups and downs during a season," Schenn said, "but you don't worry too much if the chances are coming."
Despite taking the lead on Schenn's goal, the Flyers were outplayed in the second period, getting outshot, 11-4, and spending most of the time in their defensive end.
Emery was sharp throughout the game, even though it was his first start since Jan. 23.
"It's a different preparation," Emery said of the long layoff. "On the plus side, you've had a lot of practice and a lot of rest. You can look at the positives instead of the negatives."
The positives: Steve Mason and Emery have combined for a 1.34 goals-against average and .958 save percentage as the Flyers have gone 5-1 in their last six games.
The Flyers (30-23-6) go into the break in third place in the Metropolitan Division, one point behind the second-place New York Rangers. They return to practice Feb. 19, and resume play by hosting San Jose on Feb. 27.
"We've put ourselves in a pretty good spot going through the end of the year," Emery said.
