Abstract
The invention discloses a low-pressure automatic two-way pump. The low-pressure automatic two-way pump comprises an upper cover, a base and a pump body. The low-pressure automatic two-way pump further comprises a first outlet valve, a second outlet valve and an inlet valve, wherein a first pump cavity and a third pump cavity are formed at the two sides between the pump body and the upper cover, a second pump cavity is formed in the middle part between the pump body and the base, the inlet valve penetrates through the middle part of the upper cover and the middle part of the pump body and is communicated with the second pump cavity, the first outlet valve penetrates through the base and the pump body and is communicated with the first pump cavity, and the second outlet valve penetrates through the base and the pump body and is communicated with the second pump cavity. The low-pressure automatic two-way pump is provided with one inlet and two outlets, so that the working pressure of the two-way pump is reduced, and the service life of the low-pressure automatic two-way pump is prolonged.
Description
Technical field
The present invention relates to a kind of two-way pump, particularly relate to a kind of low-pressure type automatic bidirectional pump.
Background technique
Two-way pump can when export and import position be all constant, realize the transmitted in both directions of liquid, two-way pump can be used for bidirectional fluid energy boost collector, existing two-way pump only has an import and an outlet, and make two-way pump operationally, internal pressure is large, finally cause reduce its working life, and existing two-way pump needs motor as power source, controlled inlet valve and the outlet valve of two-way pump by transmission part, this makes inlet valve and the outlet valve response lag of two-way pump.
Summary of the invention
Object of the present invention is just to provide a kind of low-pressure type automatic bidirectional pump to solve the problem.
In order to achieve the above object, present invention employs following technological scheme:
A kind of low-pressure type automatic bidirectional pump, comprise upper cover, base and the pump housing, described a kind of low-pressure type automatic bidirectional pump also comprises the first outlet valve, second outlet valve and inlet valve, both sides between the described pump housing and described upper cover are provided with the first pump chamber and the 3rd pump chamber, middle part between the described pump housing and described base is provided with the second pump chamber, described inlet valve to run through between described upper cover and the middle part of the described pump housing and communicates with described second pump chamber, described first outlet valve runs through described base with the described pump housing and to communicate with described first pump chamber, described second outlet valve runs through described base with the described pump housing and to communicate with described second pump chamber.
Particularly, the middle part of described first pump chamber and described 3rd pump chamber is respectively equipped with piezoelectricity and shakes sheet, and the middle part of described second pump chamber is provided with piezoelectricity and shakes sheet.
More specifically, the valve port place of the valve port of described inlet valve, the valve port of described first outlet valve and described second outlet valve is equipped with electromagnetic coil; The operating voltage of described electromagnetic coil is 12V direct current, and the resistance of described electromagnetic coil is 195 Ω.
Beneficial effect of the present invention is:
The present invention has an import, two outlets, decrease the pressure during work of this two-way pump, improve working life of the present invention, an inlet valve of the present invention and two outlet valves all realize opening and closing by electromagnetic coil, and liquid in pump chamber realizes the flowing of liquid by the shake up-down vibration of sheet of piezoelectricity, makes the present invention not need motor as power source, directly act on inlet valve and outlet valve, make the reaction of inlet valve and outlet valve faster.
Accompanying drawing explanation
Fig. 1 is a kind of low-pressure type automatic bidirectional of the present invention pump structure schematic diagram.
In figure: 1-upper cover, 2-first outlet valve, 3-piezoelectricity shakes sheet, 4-first pump chamber, 5-inlet valve, 6-electromagnetic coil, 7-second pump chamber, 8-the 3rd pump chamber, 9-base, the 10-pump housing, 11-second outlet valve.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, a kind of low-pressure type automatic bidirectional of the present invention pump, comprise upper cover 1, base 9 and the pump housing 10, a kind of low-pressure type automatic bidirectional pump also comprises the first outlet valve 2, second outlet valve 11 and inlet valve 5, both sides between the pump housing 10 and upper cover 1 are provided with the first pump chamber 4 and the 3rd pump chamber 8, middle part between the pump housing 10 and base 9 is provided with the second pump chamber 7, inlet valve 5 to run through between upper cover and the middle part of the pump housing 10 and communicates with the second pump chamber 7, first outlet valve 2 runs through base 9 with the pump housing 10 and to communicate with the first pump chamber 4, second outlet valve 11 runs through base 9 with the pump housing 10 and to communicate with the second pump chamber 7, the middle part of the first pump chamber 4 and the 3rd pump chamber 8 is respectively equipped with piezoelectricity and shakes sheet 3, and the middle part of the second pump chamber is provided with piezoelectricity and shakes sheet 3, the valve port place of the valve port of inlet valve 5, the valve port of the first outlet valve 2 and the second outlet valve 11 is equipped with electromagnetic coil 6, the operating voltage of electromagnetic coil 6 is 12V direct current, and the resistance of electromagnetic coil 6 is 195 Ω.
The principle of the invention is as follows:
When piezoelectricity shake sheet 3 move downward time, the electromagnetic coil 6 of inlet valve 5 is energized, under the attraction of electromagnetic force, inlet valve 5 is opened, pump chamber volume along with piezoelectricity shake sheet 3 motion and become large, pressure drop, liquid flows in pump chamber and achieves entering of liquid, when piezoelectricity shake sheet 3 move upward time, electromagnetic coil 6 power-off of inlet valve 5, inlet valve 5 cuts out, and the electromagnetic coil 6 of outlet valve is energized simultaneously, and outlet valve is opened, because pump chamber inner volume reduces, pressure increase, liquid is discharged from outlet valve, realizes the outflow of liquid.
