Description
Technical field
The utility model relates to a kind of diaphragm pump, especially relates to the improved diaphragm pump of a kind of umbrella shape one-way valve structures.
Background technique
At present, the diaphragm pump of prior art, but its one-way valve comprises the cylindricality umbrella pin of a tensile buckling and the circular umbrella cover of an elastically deformable; One end of cylindricality umbrella pin is fixed on the center bottom of circular umbrella cover, and the other end of cylindricality umbrella pin is a free end; The middle and upper part week of cylindricality umbrella pin is along outwards being provided with a projection; Correspondingly, the middle part of its one-way valve fixed block is provided with a through hole that matches with this cylindricality umbrella pin.The one-way valve of this diaphragm pump needs manually firmly the free end of cylindricality umbrella pin to be filled in the through hole of one-way valve fixed block, and the projection on the cylindricality umbrella pin is sticked in the through hole so that this one-way valve is positioned in assembly process.In addition, long cylindricality umbrella pin need be cut toward contact after this one-way valve assembles.The structure of obvious this one-way valve causes installation time longer, and assembly process is more loaded down with trivial details, and owing to need be cut the waste that has caused certain material with long umbrella pin, thereby increased the expenditure of corresponding cost.
The model utility content
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of umbrella shape one-way valve structures improved diaphragm pump, and it has simple in structure, easy to assembly, reliable and saves material, lower-cost characteristics.
The technological scheme that its technical problem that solves the utility model adopts is: the improved diaphragm pump of a kind of umbrella shape one-way valve structures comprises that gas compiles the chamber; This gas chamber of compiling comprises gas barrier chamber, one-way valve and one-way valve fixed block; The upper end of gas barrier chamber is respectively equipped with suction tude and steam outlet pipe, is connected between gas barrier chamber and the one-way valve fixed block and surrounds air-inlet cavity that is connected with suction tude and the outlet chamber that is connected with steam outlet pipe; Be provided with the inlet hole that some and described air-inlet cavity is connected in the one-way valve fixed block, the middle part of one-way valve fixed block is provided with the air outlet hole that some and described outlet chamber is connected; One-way valve is installed in the described outlet chamber; This one-way valve comprises that one makes and can cover fully the circular little shell fragment of described some air outlet holes by the rubber material; The top middle portion of circular little shell fragment is provided with one can be real in one-way valve is carried out spacing protuberance by the gas barrier constant pressure; Be provided with position structure between the bottom of circular little shell fragment and the one-way valve fixed block.
The bottom end middle part that described position structure comprises circular little shell fragment one is used to the counterbore that make described one-way valve location and with described first little column-shaped projection be complementary to what the top end middle part of one first little column-shaped projection that has and one-way valve fixed block had downwards.
What described position structure comprised that the top end middle part of groove that the bottom end middle part of circular little shell fragment upwards has and one-way valve fixed block upwards is provided with one is used to the second little column-shaped projection that makes described one-way valve location and be complementary with described groove.
Little shell fragment of described circle and described protuberance, the first little column-shaped projection are structure as a whole.
The improved diaphragm pump of a kind of umbrella shape one-way valve structures of the present utility model, during its one-way valve assembling, only need the little shell fragment of circle is placed in the outlet chamber that gas barrier chamber and one-way valve fixed block surrounded, the protuberance on the then circular submissile sheet top end is real by the gas barrier constant pressure.The bottom and the position structure between the one-way valve fixed block of circular little shell fragment have two kinds of design proposals: one is: the bottom end middle part of circular little shell fragment is to having one first little column-shaped projection, and at the top end of one-way valve fixed block middle part the corresponding counterbore that is complementary with this first little column-shaped projection of opening, when then assembling, only need the first little column-shaped projection is embedded in this counterbore, can position one-way valve; It two is: the bottom end middle part of circular little shell fragment upwards has a groove, and at the top end of one-way valve fixed block middle part the corresponding second little column-shaped projection that is complementary with this groove that is provided with, when then one-way valve assembles, similarly, only need this second little column-shaped projection is embedded in the groove, can position this one-way valve.
The beneficial effects of the utility model are: compare with the structure of the one-way valve of prior art, the one-way valve of this architecture advances, because the cylindricality umbrella pin that will have one-way valve now replaces to first little column-shaped projection or the groove of circular submissile sheet bottom end, and correspondingly open counterbore that one and the first little column-shaped projection is complementary on the top end of one-way valve fixed block downwards or on the top end of one-way valve fixed block to having one and the second little column-shaped projection that is complementary of described groove; The one-way valve of this architecture advances also upwards is provided with one at the top end of the little shell fragment of circle and is used for by the protuberance in gas barrier constant pressure jail, make that one-way valve assembling under the constant situation of performance of this architecture advances is simpler, and therefrom saved certain cost of material and man-hour.
Below in conjunction with drawings and Examples the utility model is described in further detail; But the improved diaphragm pump of a kind of umbrella shape one-way valve structures of the present utility model is not limited to embodiment.
