Description
Technical field
The utility model relates to silencer technical fields, can effectively simplify installation operation, reliability more particularly, to one kind
High suction and discharge silencer.
Background technique
Common silencer is made of plastic material, under the high temperature action of compressor, silencer be easily deformed or
Melt, can make silencer that can not eliminate the noise, or reduces noise elimination effect；Cylinder cover is mutually indepedent with silencer, and installation operation is more numerous
It is trivial.
Summary of the invention
The purpose of the invention of the present invention is to overcome cylinder cover in the prior art and silencer mutually indepedent, installation
Comparatively laborious deficiency is operated, installation operation, the suction and discharge silencer of high reliablity can effectively be simplified by providing one kind.
To achieve the goals above, the utility model uses following technical scheme:
A kind of suction and discharge silencer, including cylinder head, the noise elimination cavity being connected as one with cylinder head, be set to cylinder head and
Connecting hole between noise elimination cavity, two air inlets on noise elimination cavity；Noise elimination cavity includes upper chamber and lower chamber
Body, is equipped with baffle between upper chamber and lower cavity, baffle is equipped with notch；Two air inlets are located in lower cavity.
Gas passes through the lower cavity that two air inlets enter noise elimination cavity first, enters back into upper chamber, then gas
Entered in cylinder head by connecting hole, to effectively eliminate the noise.
The silencer and cylinder cover of the utility model are an integral structure, and amount of parts is few, are easily installed, stability
Well, high reliablity, noise elimination effect are good.
Preferably, cylinder head includes rectangle frame and the cover plate on rectangle frame；Cover plate inner surface is equipped with several pieces
Partition.Each piece of partition will be separated into several separate spaces inside cover plate.
Preferably, rectangle frame be equipped with 4 valve group screw holes, cover plate be equipped with 4 respectively with each valve group screw hole
Corresponding evacuation groove.
The valve group of rectangle frame and compressor is connected using 4 valve group screw holes, the setting of 4 evacuation grooves makes to tighten 4
The operation of a valve group screw hole is more easier.
Preferably, lower cavity side is equipped with rectangular boss, two air inlets are respectively positioned in rectangular boss.
Preferably, the junction of rectangular boss and lower cavity is equipped with U-shaped groove.Rectangular boss and U-shaped groove are set
It sets, separates two air inlets with noise elimination chamber outer surface, if noise elimination chamber outer surface has oil, oil will not slide into 2 suctions
In stomata, it is ensured that oil will not suck in lower cavity.
Preferably, the notch is in rectangle.
Preferably, the surface towards compressor of cylinder head and noise elimination cavity flushes；Noise elimination cavity is equipped with 4 boring covers
Screw hole.
Preferably, cylinder head and noise elimination cavity are all made of aluminum material and are made.
Aluminum material light weight, and can be with high temperature resistant.
Therefore, the utility model has the following beneficial effects: silencer and cylinder cover are an integral structure, components are few,
It is easily installed, stability is good, high reliablity, and noise elimination effect is good；Aluminum material, high temperature resistant.
Detailed description of the invention
