Abstract
The utility model discloses a diaphragm compressor with a new type of cylinder seal structure, comprising a cylinder cap and a cylinder body. A gas side diaphragm, a middle diaphragm and an oil side diaphragm are arranged between the cylinder cap and the cylinder body, and sealing rings are respectively installed between the cylinder cap and the gas side diaphragm, and between the cylinder body and the oil side diaphragm. An end of the cylinder cap adjacent to the gas side diaphragm and an end of the cylinder body close to the oil side diaphragm are respectively provided with a circumferential annular flute. The internal diameters of the two circumferential annular flutes are equal to the external diameters of each diaphragm, and ring flanges are respectively mounted in the two circumferential annular flutes. Sealing rings are respectively installed between the ring flange and the cylinder cap, and between the ring flange and the cylinder body. The sealing reliability of the diaphragm compressor is promoted by the structure.
Description
Technical field
The utility model relates to a kind of diaphragm type compressor.
Background technique
Diaphragm type compressor is a kind of positive displacement compressor, has two big characteristics by its structural characteristics decision diaphragm type compressor: compression ratio greatly, good airproof performance, this is the vitality place of diaphragm type compressor just also.Its groundwork principle is: reciprocating by drive mechanism piston or plunger, piston or plunger promote fluid (fluid cannot compress) the drive diaphragm pressurized gas in the oil cylinder, the volume of gas has obtained change in the film chamber, has realized the purpose of pressurized gas under the cooperation of suction, outlet valve.As shown in Figure 1, the conventional membrane compressor air cylinder structure by cylinder cap 6 ', diaphragm 8 ', 9 ', 10 ' and cylinder body 14 ' etc. form, this structure can't be satisfied the demand under to the very high situation of sealing requirements.
The model utility content
The purpose of this utility model is to provide a kind of sealing diaphragm type compressor more reliably.
For achieving the above object, technical solution of the present utility model is:
A kind of diaphragm type compressor that has novel air cylinder leakproof structure, comprise cylinder cap, cylinder body, cylinder cap, be provided with the gas latallae between the cylinder body, middle diaphragm, the oil latallae, between cylinder cap and the gas latallae, be respectively equipped with seal ring between cylinder body and the oily latallae, an end of close gas latallae on the described cylinder cap, end near oily latallae on the cylinder body is respectively equipped with a circumferential annular recess, the internal diameter of described two circumferential annular recess equates with the external diameter of described each diaphragm, in described two circumferential annular recess, be provided with ring flange, be respectively equipped with seal ring between this ring flange and the described cylinder cap and between ring flange and the described cylinder body.
Further, be processed with the Leak testtion hole on the described ring flange.
After adopting said structure,, be respectively equipped with seal ring between this ring flange and the described cylinder cap and between ring flange and the described cylinder body, therefore improved the sealing reliability of diaphragm type compressor owing to be provided with ring flange in the circumferential annular recess on cylinder cap, cylinder body; Diaphragm type compressor is widely used in compression and carries various high-purity gas, valuable rare gas, toxic and harmful and corrosive gas, its main application fields has: Aero-Space, nuclear power nuclear energy, Hydrogen Energy are utilized industry departments such as hydrogen station, food medicine, petrochemical industry, electronics industry, material industry, defence and military and scientific experimentation, so the raising of its sealing reliability has society and economy benefit widely.
