Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1-3, a centrifugal air compressor volute comprises a volute body 1, an air vent 2, a fixing ring 3 and a baffle 9, wherein an air outlet pipe 5 is welded at one end of the volute body 1, an air inlet 4 is formed in the top of the volute body 1, the bottom of the volute body 1 is connected with the fixing ring 3 through a thread groove, a fixing groove 7 is formed in the fixing ring 3, a ball 8 is mounted on the inner side of the fixing groove 7 through a mounting groove, an arc-shaped block 6 is welded on the inner side of the volute body 1, and the air vent 2 is formed in the outer side of the volute.
Wherein, the quantity of ball 8 and arc piece 6 is a plurality of.
In this embodiment, as shown in fig. 3 and 5, after the impeller rotating shaft is inserted into the fixing groove 7, the plurality of balls 8 can improve the structural stability and the smoothness of rotation, and the plurality of arc-shaped blocks 6 can block the air entering the volute body 1 to change the flow direction of the air, so that the impeller rotates to collect the wind in the volute body 1.
Wherein, the inside baffle 9 that installs through the mounting groove of air vent 2, the centre gripping has small-size spring 10 between baffle 9 and the air vent 2.
In this embodiment, as shown in fig. 4, when the air inside the volute body 1 flows into the vent hole 2, the baffle 9 loses suction force, and the vent hole 2 is blocked by pushing one end of the top vent hole 2 by the small spring 10, so as to prevent the air inside the volute body 1 from flowing away.
Wherein, the baffle 9 is made of hard rubber material.
In this embodiment, as shown in fig. 4, the baffle 9 made of hard rubber material can be sucked by the suction force generated by the rotation of the impeller.
It should be noted that, the utility model relates to a centrifugal air compressor volute, when in use, a fixing ring 3 is screwed in and installed in a thread groove at the bottom in the volute body 1 through threads, a fixing groove 7 is arranged in the fixing ring 3 to facilitate the rotation insertion and fixation of an impeller, the thread groove at the bottom in the volute body 1 can be protected and is not easy to deform, a plurality of balls 8 are evenly embedded in the inner side of the fixing groove 7, when the rotating shaft of the impeller rotates, the balls 8 rotate to improve the smoothness of the rotation of the impeller and the structural stability after installation, a plurality of arc-shaped blocks 6 are welded on the inner side of the volute body 1 to block air entering the volute body 1 and change the flowing direction of the air, thereby the wind gathering capacity in the volute body 1 when the impeller rotates and not affecting the rotation of the impeller, when the impeller rotates at high speed in the vent hole 2, make the inside suction that produces of spiral case body 1, with inside the outside air suction spiral case body 1, simultaneously, can inhale baffle 9 and remove, baffle 9 removes the back, and outside air can be followed vent hole 2 and got into in spiral case body 1, improves its intake, and when the inside air of spiral case body 1 flows to vent hole 2 is inside, baffle 9 loses suction, and top vent hole 2 one end is plugged up vent hole 2 under the promotion of small-size spring 10, prevents that the inside air of spiral case body 1 from running off.
