To state membrane and left chamber is divided into left fluid chamber and left air chamber, right chamber is divided into right fluid chamber and right air chamber by membrane,
Check valve is respectively connected between left chamber and feed-inputing branched pipe and discharging branch pipe, the bottom and top of right chamber are close by blind plate
Envelope, the left air chamber are connected with right fluid chamber by a connecting pipe.
Further, the driving device is air motor.
Further, the driving device is connected with muffler.
Further, the check valve includes valve ball, gasket ring and the sealing ring set gradually.
Further, it is both provided with packing ring between the blind plate and right chamber.
The utility model has the advantage of：
1st, the suction of diaphragm pump can be effectively improved, ideally can double the Fluid pressure of output.
2nd, it is simple in structure, easy to safeguard.
3rd, it is safe using air motor, inflammable and explosive medium fluid can be conveyed.

Embodiment
For limited pressure caused by solving general Pneumatic double diaphragm pump work, more sticky medium can not be conveyed
The problem of fluid, there is provided high-pressure pneumatic twin-diaphragm pump.
Make the purpose, technical scheme and advantage of the utility model embodiment clearer, below in conjunction with the utility model
Attached drawing in embodiment, carries out the technical scheme in the embodiment of the utility model clear, complete description, it is clear that described
Embodiment be the utility model part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art obtain without making creative work, belongs to this
The scope of utility model protection.
High-pressure pneumatic twin-diaphragm pump as shown in Figures 1 to 3, including left chamber 1, right chamber 2 and between the two driving dress
3 are put, left chamber 1,2 bottom of right chamber are provided with a feed-inputing branched pipe 4, and top is provided with a discharging branch pipe 5, the left chamber 1, the right side
It is both provided with membrane 6 in chamber 2, left chamber 1 is divided into left fluid chamber 11 and left air chamber 12 by the membrane 6, and membrane 6 is by the right side
Chamber 2 is divided into right fluid chamber 21 and right air chamber 22, and list is respectively connected between left chamber 1 and feed-inputing branched pipe 4 and discharging branch pipe 5
To valve, the bottom of right chamber 2 is sealed with top by blind plate 8, and the left air chamber 12 is connected with right fluid chamber 21 by one
Pipe 9 connects.In actual use, since blind plate 8 closes right chamber 2, liquid cannot be introduced into right chamber 2, and left air chamber 12 with
Right fluid chamber 21 connects, therefore can be obtained than general twin-diaphragm pump more in left fluid chamber 11 from the fluid that feed-inputing branched pipe 4 is pumped into
Big pressure.
The driving device 3 is air motor.Air motor can be used for the conveying of flammable explosive gas, safe.
The driving device 3 is connected with muffler 10.Muffler 10 can effectively reduce gas caused by air motor work
Flow noise.
