Abstract
The utility model relates to a high-tightness air cylinder which comprises a cylinder as well as an upper end cover and a lower end cover matched with the cylinder, wherein the outer side of the upper end cover is in sealed connection with at least one air inlet; the outer side of the lower end cover is in sealed connection with at least one air outlet; an upper flange bent inward and matched with the cylinder is arranged on the edge of the upper end cover; a lower flange bent inward and matched with the cylinder is arranged on the edge of the lower end cover; the upper flange and the lower flange are connected with the cylinder by welding; sealants are arranged at the matched parts between the upper flange and the lower flange and the cylinder; and two support rods for setting the upper flange and the lower flange respectively are arranged in the cylinder. Through the flanges and the sealants at the joint, the air cylinder can effectively improve the sealing performance of an inner cavity of the air cylinder and improve the sealing performance at the joint.
Description
Technical field
The utility model relates to the field of pressurized container, especially a kind of high leak tightness gas receiver.
Background technique
Gas receiver mainly is used for the gas that the stored air compressor compresses is come out, and is requisite energy-storing container in the pneumatic system, and for example: vehicles such as automobile, motorcycle need be equipped with corresponding gas receiver.
Present employed gas receiver generally is made up of cylindrical shell, upper end cap and lower end cap; Upper end cap all is connected with cylindrical shell through the mode of welding with lower end cap; Because weld port is the butt welding between plane port and the plane port; So be easy to cause welding imperfect, poor sealing performance, and then cause phenomenon such as gas leakage easily.
The model utility content
The technical problem that the utility model will solve is: in order to overcome the problem that proposes in the above-mentioned background technology; The utility model provides a kind of high leak tightness gas receiver, and the design that it utilizes flanging and sealing compound is set in the joint can improve the sealability and the sealability that improves the joint of gas receiver inner cavity effectively.
The utility model solves the technological scheme that its technical problem adopted: a kind of high leak tightness gas receiver; Have cylindrical shell, the upper end cap that matches with cylindrical shell and lower end cap; The upper end cap outside is sealedly connected with at least one suction port; The lower end cap outside is sealedly connected with at least one air outlet; The edge of upper end cap is provided with the upper hem that curves inwardly and match with cylindrical shell, and the edge of lower end cap is provided with the lower hem that curves inwardly and match with cylindrical shell, and upper hem and lower hem and cylindrical shell are all through being welded to connect; The cooperation place of upper hem and lower hem and cylindrical shell is provided with sealing compound, is provided with two in the cylindrical shell and is used for respectively finalizing the design and supports the strut of upper hem and lower hem.
Further: cylindrical shell barrel thickness is 1.5～2.5mm.
Further: the quantity that is sealedly connected on the suction port in the upper end cap outside is three.
Further: cylindrical shell is processed by stainless steel.
The beneficial effect of the utility model: the design that this gas receiver utilizes flanging and establishes sealing compound in the joint can improve the sealability and the sealability that improves the joint of gas receiver inner cavity effectively; Being arranged on strut in the cylindrical shell can well finalize the design for supporting and go up lower hem; Can improve the sealing of gas holder equally; Simple in structure, good seal performance can effectively be avoided the generation of gas leak phenomenon.
