Abstract
The utility model provides a diaphragm pump with a double-sealing structure and belongs to the technical field of diaphragm pumps. The diaphragm pump with the double-sealing structure comprises a pump head cover, a diaphragm chamber, a diaphragm sheet, a pump head seat and a balance wheel seat, wherein the pump head cover, the diaphragm chamber, the diaphragm sheet, the pump head seat and the balance wheel seat are all connected in a matched mode. The diaphragm pump with the double-sealing structure is characterized in that the diaphragm sheet is provided with an upper sealing ring and a lower sealing ring, the pump head cover is correspondingly provided with an upper sealing groove which is connected with the upper sealing ring in an embedded matched mode, and the pump head seat is provided with a lower sealing groove which is connected with the lower sealing ring in an embedded matched mode. The diaphragm pump with the double-sealing structure is simple in assembling process, stable in assembly and low in cost. The pump head cover, the diaphragm chamber, the diaphragm sheet and the pump head seat are assembled to form the complete double-sealing structure, sealing invalidation time limit caused by micro deformation due to the facts the pump head cover, the diaphragm chamber, the diaphragm sheet and the pump head seat are under the action of water pressure for a long time and materials age is effectively prolonged, the sealing performance of the pump is guaranteed after one way of sealing is invalid, and technical requirements are met.
Description
Technical field
The utility model belongs to the diaphragm pump technical field, is specially a kind of diaphragm pump with double sealing structure.
Background technique
The reverse osmosis water purification machine is from the pressurized part barrier film pump structure of its core till now that is born; Mainly still adopt the diaphragm technology; Cooperate the seal ring of processing with flexible material to be combined in addition and prevent the structure of the liquid of pump supercharging generation to motor internal and the outside seepage of the pump housing; Like the patent No. is that the Chinese utility model patent " a kind of diaphragm structure of diaphragm pump " of N201120164210.6 is just to being connected between diaphragm and the escapement seat; Design the double leak-proof structure, solved diaphragm and escapement seat joint to the motor internal leakage problems, but the Seal Design between diaphragm and pump cover and the pump head seat has still had certain deficiency.
The model utility content
To the problems referred to above that exist in the existing technology, the purpose of the utility model is to design a kind of technological scheme with diaphragm pump of double sealing structure, its good sealing effect, easy to assembly, long service life is provided.
Described a kind of diaphragm pump with double sealing structure; Comprise the pump head lid, chamber of septum, diaphragm, pump head seat, the escapement seat that are connected; It is characterized in that being provided with on the diaphragm seal ring, lower seal; Pump head covers the last sealed groove of correspondence setting and last seal ring interlocking close-fitting, and corresponding setting and lower seal are rabbeted the lower seal groove of close-fitting on the pump head seat.
Described a kind of diaphragm pump with double sealing structure, it is characterized in that pump head cover be provided with one the circle sealed muscle, the interlocking end face crimping close-fitting of sealed muscle and lower seal, lower seal groove.
Described a kind of diaphragm pump with double sealing structure is characterized in that on the pump head seat positioning block being set, and pump head covers correspondence locating slot is set.
Described a kind of diaphragm pump with double sealing structure is characterized in that described upward seal ring is upwardly extending circular fold structure, and described lower seal is that lower seal is positioned at the periphery of seal ring to the circular fold structure that extends below.
Above-mentioned a kind of diaphragm pump with double sealing structure; Assembly technology is simple, and assembly is stable, and is with low cost; Pump head lid, chamber of septum, diaphragm, pump head seat combination back form complete double sealing structure; Can effectively prolong pump head lid, chamber of septum, diaphragm, pump head seat because of the micro-deformation that under the long-term hydraulic action and the aging back of material self produces causes the seal failure time limit, after the single track seal failure, still can guarantee the pump seal performance, meet technical requirements.
