Background technique
Pneumatic diaphragm pump is a kind of positive displacement pump for trandfer fluid class or powdery type.It is pushed away using compressed air as power
Dynamic diaphragm movement, once having arrived extreme position, compressed air distributing valve changes the disengaging direction of compressed gas automatically, to change
The direction of motion of diaphragm, makes it constantly move back and forth, then is pumped by the cooperation of four check valves in inlet/outlet pipe to reach
The purpose of medium is a kind of very widely used pump.
The working principle of existing pneumatic diaphragm pump is after high pressure gas enters in valve cage, to enter two by reversal valve
It one in air cavity, heaves the air cavity interior diaphragm and reaches range, two latallaes are connected by pitman shaft, when side reaches
When to range, another latallae is pulled to minimum stroke, when diaphragm is pulled to minimum stroke, connected pressing plate
It then will push assist rod, and assist rod is then the reversing arrangement for controlling reversal valve, it slides reversal valve to change high pressure gas
Body is communicated in the air cavity of the other side, achievees the purpose that left and right does not stop sliding as a circulation.Existing pneumatic diaphragm
The reversing arrangement pumped inside valve cage is two individual parts, when one of failure Shi Douhui causes diaphragm pump to stop
Work, and due to needing separate machined, cost can be higher.Existing pneumatic diaphragm pump gas circuit adds all inside valve cage
Work, required precision is higher, complex-shaped, causes processing cost high, error is larger.It installs more complex.The gas of existing diaphragm pump
The contact plane of source inlet and reversal valve is horizontal layout, and due to Bernoulli's theorem, swiftly flowing gas can make on reversal valve
Square pressure reduces, and will lead to it can not mutually be adjacent to matched bootstrap block, causes gas to leak, reduces working efficiency,
Waste gas source.

Complete commutation.
Advantageously, also have in the rear surface of air valve body described in the reversing valve assembly of the pneumatic diaphragm pump and be located at upper company
Gas vent 605 between through-hole 601, lower intercommunicating pore 602, left connection hole 603 and right intercommunicating pore 604.It not will cause and suppress as a result,
Pressure.
Advantageously, the reversing valve assembly of the pneumatic diaphragm pump further includes multiple sealing rings 610, multiple sealing rings 610
It is located to time interval on the periphery wall of air valve body 600.Thereby it is ensured that leakproofness.
A kind of pneumatic diaphragm pump according to the present utility model, in the operating condition, upper and lower piston controls to be changed commutation sliding block
It is slided up and down to sliding block to change high pressure gas and enter in different air cavitys, pitman shaft drives take-up housing and then drives commutation sliding block
It horizontally slips to change high pressure gas and enter in different piston chamber.
The front end of take-up housing is suitable for sliding up and down commutation sliding block, and take-up housing is connected with pitman shaft, the left and right of pitman shaft
The mobile take-up housing that will drive is mobile, and take-up housing moves left and right, and will drive commutation sliding block again and is moved left and right, to make to connect
The Influence of Displacement of bar axis is entered to high pressure gas in different piston chamber, so that changing high pressure gas enters different air cavitys
It is interior, to achieve the purpose that commutation.
Air valve body is the device for guiding gas, there is sealing device of multiple sealing rings as isolation connectivity layer on air valve body,
There are five hole, respectively intermediate gas vent, upper and lower air cavity intercommunicating pore, the piston intercommunicating pores of left and right for bottom.When diaphragm pump work
When making, commutation sliding block is ceaselessly up and down by rule sliding to control in a manner of gas connection to make pitman shaft or so not stop
Movement.
The air inlet of valve cage is arranged symmetrically with air valve body, and when high pressure gas enters in valve cage, high pressure gas can be straight
It connects and blows to commutation sliding block to which the sliding block that makes to commutate is close to air valve body, reduce the leakage of high pressure gas, increase the use effect of gas source
Rate improves work efficiency.
A kind of pneumatic diaphragm pump according to the present utility model dexterously ties two reversing arrangements of original pneumatic diaphragm pump
It has closed on a commutation sliding block, to reduce the usage amount of valve cage inner body, so that failure rate is reduced.Due to tradition
The gas circuit of diaphragm pump leads to complex process all in valve cage, and precision is low, and new structural pneumatic diaphragm pump then places gas circuit
In the smaller air valve body of volume, so that processing efficiency is higher, installation is more convenient, to reduce costs.Due to changing for structure
Become, new structural pneumatic diaphragm pump is dexterously utilized high pressure gas and is allowed to blow to reversal valve, and commutation sliding block is enable to utilize gas
It overlays on tight air valve body with matching, being unlikely to resistance while playing sealing function again can not slide greatly very much, from
And the utilization rate of high pressure gas is improved, it improves work efficiency.
