Description
Technical field
The utility model relates to a kind of rectangular diaphragm accumulators, belong to hydraulic accumulating device technical field.
Background technique
Diaphragm accumulator is one of hydraulic system energy savings device, its working principle is by the energy in system
Being changed into compression energy or displacement can store, can be by that can turn compression energy or displacement when system pressure reduces
Become hydraulic energy and release, the pressure of hydraulic system is kept to stablize.As the critical component of accumulator, diaphragm of rubber should
The separation of stringent ne-leakage, Seal Oil, air cavity withstand up to the alternating bending deformation of 100 degree or more of operating temperature again, and
Long-term work at high temperature under high pressure, therefore diaphragm easily damages.
Utility model content
In view of the above-mentioned problems, the technical problem to be solved by the present invention is to provide a kind of rectangular diaphragm accumulators.
The rectangular diaphragm accumulator of the utility model, it includes protective cap, national standard charge valve, washer, upper housing, the first O
Type circle, lower case, the second O-ring, diaphragm, stopping-off piece and third O-ring, the upper housing lower section are provided with lower case,
And the junction of upper housing and lower case is provided with the first O-ring, is provided with national standard charge valve, and state above the upper housing
Protective cap is provided with outside mark charge valve, the national standard charge valve and upper housing junction are provided with washer, the upper casing
Cavity is formed between body and lower case, and is provided with diaphragm in cavity, and stopping-off piece is provided on the diaphragm, it is described
Lower case external upper is provided with the second O-ring, and lower case outer lower side is provided with third O-ring.
Preferably, first O-ring, the second O-ring and third O-ring are all made of nitrile rubber and are made, and hard
Degree reaches 75-90 ° of shore.
The utility model has the beneficial effects that its structure is simple, rationally, diaphragm is equipped with stopping-off piece, to diaphragm for design
Piece plays a good protective effect, and impact resistance is improved, to extend the service life of diaphragm, while upper housing and lower case
Between be equipped with O-ring, ensure that diaphragm integrally good leakproofness.
Detailed description of the invention
The present invention is described in detail by the following detailed description and drawings for ease of explanation,.
Fig. 1 is the overall structure cross-sectional view of the utility model；

Appended drawing reference: protective cap 1, national standard charge valve 2, washer 3, upper housing 4, the first O-ring 5, lower case 6, second are O-shaped
Enclose 7, diaphragm 8, stopping-off piece 9, third O-ring 10.
Specific embodiment
As shown in Figure 1-Figure 3, present embodiment uses following technical scheme: it includes protective cap 1, national standard charge valve
2, washer 3, upper housing 4, the first O-ring 5, lower case 6, the second O-ring 7, diaphragm 8, stopping-off piece 9 and third O-ring 10, institute
Lower case 6 is provided with below the upper housing 4 stated, and the junction of upper housing 4 and lower case 6 is provided with the first O-ring 5, it is described
Upper housing 4 above be provided with national standard charge valve 2, and protective cap 1 is provided with outside national standard charge valve 2, the national standard inflation
Valve 2 and 4 junction of upper housing are provided with washer 3, and cavity, and setting in cavity are formed between the upper housing 4 and lower case 6
There is diaphragm 8, stopping-off piece 9 is provided on the diaphragm 8,6 external upper of lower case is provided with the second O-ring 7,

Working principle: forming air cavity between upper housing 4 and diaphragm 8, sap cavity is formed between lower case 6 and diaphragm 8, will
Diaphragm accumulator is connect with hydraulic system, is full of nitrogen by authorized pressure to accumulator by national standard charge valve 2, is worked as high-pressure and hydraulic
When oil pressure reaches pulse crest value, is squeezed by oilhole and push diaphragm 8, make 8 alternating compression nitrogen of diaphragm.It is hydraulic at this time
Elastic potential energy can be converted into be stored in compressed nitrogen.When high pressure liquid pressure value is to pulse valley value, compressed nitrogen
Gas is given off energy and is added in liquid due to environmental liquids pressure reduction, and the elastic potential energy in nitrogen is converted into hydraulic at this time
Energy.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
