Abstract
The utility model relates to a muffler with an exhaust diffusion pipe. The muffler possesses a hat form structure, wherein the bottom is circular, the middle is provided with a convex structure upward, the middle of the convex structure is provided with a through hole for arranging a cylinder cover, the convex structure is provided with a diffusion pipe, and the caliber of the diffusion pipe becomes larger gradually from the connection end with the convex structure. Compared to the prior art, in the utility model, when the exhaust stream of a compressor passes through the diffusion pipe, the velocity of the exhaust stream is reduced, the pressure is increased, the pressure at the inlet of the diffusion pipe is smaller than the pressure at the outlet of the diffusion pipe, which indicates that the pressure in the muffler is smaller than the exhaust outlet of the muffler, thereby the backpressure of the exhaust valve sheet of the compressor is reduced, the overcompression loss of the compressor is reduced, and the efficiency of the compressor is raised.
Description
Technical field
The utility model relates to a kind of compressor air-discharging equipment, especially relates to a kind of baffler with exhaust diffuser pipe.
Background technique
During compressor air-discharging process baffler, because the fluid resistance losses of baffler, the pressure in the baffler can be higher than the pressure in the housing, thereby make the exhaust overcompression loss increase of compressor.
The design of compressor silencer is not only influential to reducing noise, and it also has very important influence to the compressor heat mechanical property.
Present compressor silencer is generally the circular port structure; When gas stream is crossed baffler, can produce very big fluid resistance losses, make pressure in the baffler greater than the pressure in the compressor housing; Thereby cause the back pressure of Compressor Air Exhaust Valve Plate to increase, make the overcompression loss of compressor increase.
The model utility content
The purpose of the utility model is exactly for the defective that overcomes above-mentioned existing technology existence a kind of overcompression loss that reduces compressor to be provided, and improves the baffler with exhaust diffuser pipe of compressor efficiency.
The purpose of the utility model can realize through following technological scheme:
A kind of baffler with exhaust diffuser pipe; Baffler is a hat-shaped structure, and the bottom is rounded, and the centre is provided with protruding structure upwards; The middle part of this protruding structure is provided with the through hole that cylinder cap is installed; It is characterized in that protruding structure is provided with diffuser pipe, the caliber of diffuser pipe enlarges from the connecting end with protruding structure gradually.
Described diffuser pipe is positioned at the center at protruding structure top, a side at protruding structure top or the side of protruding structure, and the connection part of diffuser pipe and protruding structure is a relief opening.
The cross section of described diffuser pipe is circle, D shape or ellipse.
Taper shape, ellipse or the polygon structure of described diffuser pipe for enlarging gradually from connecting end with protruding structure.
The outward extending direction of described diffuser pipe is rectilinear direction or Hand of spiral.
Compared with prior art, when the utility model can make compressor bleed air flow cross diffuser pipe, the blast air prompt drop was low; Pressure raises; Make the gas pressure of diffuser pipe inlet less than the pressure of diffuser pipe outlet, promptly the pressure in the baffler is less than the pressure of baffler exhaust outlet, thereby reduces the back pressure of Compressor Air Exhaust Valve Plate; Reduce the overcompression loss of compressor, improve compressor efficiency.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Baffler with exhaust diffuser pipe is shown in Fig. 1～2; Baffler is a hat-shaped structure; The bottom is rounded, and the centre is provided with protruding structure 1 upwards, and the middle part of protruding structure 1 is provided with the through hole that cylinder cap 3 is installed; Connect the diffuser pipe 2 that area enlarges gradually on this protruding structure 1, diffuser pipe 2 is a relief opening with the connection part of protruding structure 1.The installation effect of baffler with exhaust diffuser pipe is as shown in Figure 3, and exhaust is flowed out from the slit of cylinder cap 3 both sides and flowed out bafflers through diffuser pipe 2, and through cross section 1 and cross section 2, the gas pressure on the cross section 1 is P1, and gas flow rate is u1; Gas pressure on the cross section 2 is P2, and gas flow rate is u2.Because the flow area in cross section 2 is greater than cross section 1, then u2＜u1; Have the Bernoulli's equation in the fluid mechanics can know P2＞P1, the gas that flows through has been realized the increase of pressure when flowing through the diffuser pipe of baffler.And P2 is the pressure in the compressor housing, thus the pressure in the baffler be reduced, thereby reduce the back pressure of Compressor Air Exhaust Valve Plate, reduce the overcompression loss of compressor, improve compressor efficiency.
