Specific implementation mode
It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.Only this state, the utility model occur in the text or will occur upper and lower, left and right, it is preceding,
Afterwards, the orientation such as inside and outside word is not the specific restriction to the utility model only on the basis of the attached drawing of the utility model.
Referring to attached drawing 1 to attached drawing 5, the utility model discloses a kind of one-way valve structures, including elastic piece 2 and end phase
The inlet suction port 1 and air outlet adapter 3 of connection, the inlet suction port 1 and air outlet adapter 3 form regulation and control chamber 4 at the position of connection,
The inlet suction port 1 is equipped with the inlet channel 11 being connected to regulation and control chamber 4, and the air outlet adapter 3 is equipped with to be connected to regulation and control chamber 4
Outlet passageway 31.The elastic piece 2 is installed in regulation and control chamber 4, and the air outlet adapter 3, which is equipped with, to be located in regulation and control chamber 4
Lug boss 30, the lug boss 30 and the centre of elastic piece 2 are oppositely arranged.The elastic piece 2 under momentum effect with tune
Mutually it is close to or is bent to 3 direction of air outlet adapter in the bottom surface of control chamber 4.Wherein, the elastic piece 2 is sheet rubber.
When inlet channel 11 is passed through gas or liquid, the elastic piece 2 is under momentum effect to outlet passageway direction
It is mobile, and the center portion thereof position is close to lug boss 30, edge is bent to 3 direction of air outlet adapter, so that gas or liquid
Body is flowed by the gap between elastic piece 2 and inlet suction port 1 in regulation and control chamber 4；On the contrary, when outlet passageway 31 be passed through gas or
When liquid, the elastic piece 2 is mutually close under momentum effect with the bottom surface of regulation and control chamber 4, so that inlet channel 11 and regulation and control chamber
Room 4 is isolated.
The utility model by regulation and control chamber 4 in setting elastic piece 2 to control the one-way flow of gas or liquid,
When gas or liquid in inlet channel 11 by flowing into, elastic piece 2 can be by the impulse force to outlet passageway 31, since outlet connects
First 3 are equipped with lug boss 30 in regulation and control chamber 4, and the elastic piece 2 is when by the blocking of lug boss 30, the center of elastic piece 2
It is to be close to lug boss 30, the edge of elastic piece 2 still can be bent by impulse force to 3 direction of air outlet adapter, at this point, elastic piece 2
Passage gaps can be formed between the inner wall of regulation and control chamber 4, thus the gas and liquid flowed by inlet channel 11 can circulate between
Clearance flow enters in chamber 4, and the gas or liquid flowed into regulation and control chamber 4 is flowed out under the promotion of air-flow by outlet passageway 31.
On the contrary, when gas or liquid in outlet passageway 31 by flowing into, elastic piece 2 can be by 11 direction of inlet channel
Impulse force, at this point, elastic piece 2 can by inlet channel 11 and regulation and control chamber 4 be isolated, to stop the circulation of gas or liquid.
As it can be seen that the utility model has the advantages of simple structure, it is only necessary to be put into elastic piece 2 in regulation and control chamber 4, install
