Abstract
The utility model discloses a diapragm compressor belongs to compressor technical field. Include that the membrane that separates cylinder body, diaphragm, admission valve, air bleeding valve, installs on the cylinder body covers. The cylinder body with the composition surface department of membrane lid is provided with the diaphragm chamber, the diaphragm is installed with the diaphragm of diaphragm chamber partition for gaseous chamber and hydraulic pressure chamber to the diaphragm intracavity, the hydraulic pressure oil duct that is provided with the piston on the hydraulic pressure chamber and feeds through with the cylinder body, the membrane is covered and is provided with air bleeding valve, the snifter valve that communicates with gaseous chamber the snifter valve is provided with the filter screen with the junction of membrane lid. The utility model discloses simple structure, convenient to use, effectual prevention spring piece and other impurity get into the diaphragm chamber, prevent that the diaphragm from breaking, the membrane head injured.
Description
Technical field
The utility model relates to a kind of diapragm compressor, belongs to Compressor Technology field.
Background technique
Diapragm compressor is by barrier film peripherally by two confinement plate pinched composition air cavitys, and barrier film drives to-and-fro motion in cylinder by mechanical or hydraulic pressure, air pressure valve, thus the compression realized gas and conveying.Traditional air valve runs for a long time under the high temperature conditions, and spring easily occurs that fatigue fracture enters compressor diaphragm chamber.
Model utility content
For solving the problem, the utility model provides a kind of structure simple, diapragm compressor easy to use.
The technological scheme that the utility model adopts for its problem of solution is:
A kind of diapragm compressor, comprises every cylinder body, barrier film, suction valve, outlet valve, the membrane cover be arranged on cylinder body.The mating face place of described cylinder body and described membrane cover is provided with diaphragm chamber, is provided with the diaphragm that diaphragm chamber is divided into air chamber and hydraulic pressure cavity by diaphragm in described diaphragm chamber; The hydraulic pressure oil duct described hydraulic pressure cavity being provided with piston and being communicated with cylinder body; Described membrane cover is provided with the outlet valve, the Aspirating valves that are communicated with air chamber, the junction point of described Aspirating valves and membrane cover is provided with filter screen.
Preferably, described membrane cover is provided with in some air flues and diaphragm chamber is provided with diaphragm.
Preferably, described cylinder body is provided with piston cylinder, described piston is slidably arranged in described piston cylinder.
The beneficial effects of the utility model are: structure is simple, easy to use, and effective spring fragment and other impurity of stoping enters diaphragm chamber, prevents rupture of diaphragm, film head injured.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structure sectional view of the present utility model;
Fig. 2 is the enlarged diagram in A portion in Fig. 1.
In figure: 1, cylinder body; 2, membrane cover; 3, diaphragm chamber; 4, diaphragm; 5, piston; 6, oil duct; 7, oilhole; 8, piston cylinder; 9, outlet valve; 10, Aspirating valves; 11, filter screen.
Embodiment
A kind of diapragm compressor as shown in accompanying drawing 1,2, comprise cylinder body 1, the membrane cover 2 be arranged on cylinder body 1 one end face, described cylinder body 1 is provided with diaphragm chamber 3 with the mating face place of described membrane cover 2, the diaphragm 4 diaphragm chamber 3 being divided into two cavitys is installed in described diaphragm chamber 3, the middle part of membrane cover 2 and cylinder body 1 all forms depression, after membrane cover 2 and diaphragm cavity 1 are installed and are engaged, the end of diaphragm 4 is clamped by the position that the surrounding of membrane cover 2 and diaphragm cavity 1 does not cave in, sunk part then forms diaphragm chamber 3, and is divided into two parts in left and right by diaphragm 4.The oil duct 6 described cylinder body 1 being provided with piston 5 and being communicated with diaphragm chamber 3, described cylinder body 1 is provided with the oilhole 7 of some connection oil ducts 6 and diaphragm chamber 3.Described diaphragm cavity 1 is provided with piston cylinder 8, and described piston 5 is slidably arranged in described piston cylinder 8, and piston cylinder 8 can adopt separately the material of rub resistance to make, and with the face of piston 5 sliding contact through polishing treatment, so both cost savings, again convenient processing.Described membrane cover 2 is provided with the outlet valve 9 and Aspirating valves 10 that are communicated with described diaphragm chamber 3, when piston 5 slides, can diaphragm chamber 3 be pressurizeed or be reduced pressure, when pressurized, outlet valve 9 is subject to the air pressure of diaphragm chamber 3 inside and opens, and discharges air, when reducing pressure, diaphragm chamber 3 inside forms the negative pressure being less than external pressure, and Aspirating valves 10 is promoted by outside atmosphere, and outside air enters in diaphragm chamber 3.When outside air enters diaphragm chamber 3 from Aspirating valves 10, according to the situation of working environment, fragment may be had and together enter, therefore, described Aspirating valves 10 and the junction point of membrane cover 2 are provided with filter screen 11, and the effective spring that stops enters diaphragm chamber 3, prevents that diaphragm 4 from breaking, film head is injured.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and model utility design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
