The air valve component disclosed by the utility model has the advantages that since the air is used as power, the flow can be automatically adjusted along with the change of the resistance of an outlet, and can adapt to the conveying of fluid with medium-high viscosity automatically.
Description
Technical field
The utility model relates to the Pneumatic Transmission technical field, relates in particular to a kind of air-valve assembly for two chambers diaphragm pump.
Background technique
Diaphragm pump is a kind of novel conveying mechanism, and the fluid that can carry is very extensive, from low viscous to full-bodied, to poisonous inflammable and explosive, is the nucleus equipment that the remote pipeline of solid liquid media is carried from corrosive.Diaphragm pump generally is made up of actuator, pump body and valve.Actuator goes to change fluid flow and the flow direction by control signal by power operation.Diaphragm pump is by the power that actuator uses, can be divided into electronic, surge, pneumatic three kinds.With electronic electric diaphragm pump as power source, the power of actuator is determined by variable-frequency motor that mostly load can not be excessive or too small when variable-frequency motor required startup and stops pump, otherwise frequency variator is fragile; During many and complicated component, pipeline is easy to stop up when the impurity in the discharge of wastewater, and it is too high to produce load, and motor easily generates heat impaired.It is the electricity of the power diaphragm pump that surges with the medium pressure liquid, be that medium promotes diaphragm of rubber and does concavo-convex motion and make the medium volume cyclically-varying in the pump housing finish conveying with liquid, hydraulic regulation precision height, steady, but the complicated easily leakage pollution environment of hydraulic pipe line, difficult maintenance has certain requirement to working environment.Being the membrane pump with pneumatic drive of power source with pressurized air (nitrogen or rock gas), is that pneumatically is as motivational drive.Gas distributing valve is by electromagnetic valve in the market, by the limit position near switch perception barrier film, be exclusively used in and control the solenoid valve commutation after pump electrical control original paper is received signal, thereby change the flow direction of gas, change flow and the flow direction of pump fluid, pump electrical control original paper is to the environmental requirement height, and solenoid valve is fragile, needs the professional person to safeguard.And the proper functioning of pump needs the support of electricity, the electric energy that pump consumes is very big, the analysis result that external certain producer drops into for a long time to water pump: purchase cost accounts for 8%, maintenance cost accounts for 7%, power consumption accounts for 85%, the maximum fund that pump expended in its working life is not first purchase cost, neither maintenance cost, but the electric energy of its consumption.According to incompletely statistics, 20%-25% of annual national generating capacity will consume on the pump product, and power consumption becomes a difficult problem of pump valve industry development.
Summary of the invention
The purpose of this utility model is to provide a kind of and exempts to lubricate, do not have leakage, the air-valve assembly that is used for two chambers diaphragm pump easy to maintenance.
The utility model is to realize like this, a kind of air-valve assembly for two chambers diaphragm pump, commutation valve body, main directed air valve body, pilot valve valve body in the middle of comprising, it is characterized in that: be provided with the pilot valve spool in the described pilot valve valve body, fixedly there is drive plunger at pilot valve spool two ends, are arranged with the barrier film connecting rod in parallel below the described drive plunger; Be provided with the C chamber between the directed air valve body of described master and the main directed air valve spool, main directed air valve body below is provided with baffler, and described baffler is provided with the baffler lid.
The utility model so flow can be adjusted automatically with the variation of resistance to flow output, can adapt to the conveying of the fluid of medium-high viscosity owing to be used as power with air automatically; Do not need water during the utility model work; only need open gas valve; air-valve assembly work; pump namely automatically sucks water, has self-absorption function, when the membrane pump with pneumatic drive overburdening or when closing pump discharge; pump meeting autostop; have the self-protection performance, after normal or outlet is opened when load restoration, can start operation automatically again.

Concrete mode of execution
The present invention is further described below in conjunction with drawings and embodiments:
A kind of air-valve assembly for two chambers diaphragm pump, commutation valve body 2, main directed air valve body 3, pilot valve valve body 8 in the middle of comprising, it is characterized in that: be provided with pilot valve spool 7 in the described pilot valve valve body 8, fixedly there is drive plunger 9 at pilot valve spool 7 two ends, are arranged with barrier film connecting rod 10 in parallel below the described drive plunger 9; Be provided with C chamber 13 between the directed air valve body 3 of described master and the main directed air valve spool 6, main directed air valve body 3 belows are provided with baffler 5, and described baffler 5 is provided with baffler lid 4.
Discharge stroke: main directed air valve spool 6 is directed to valve and activates back (as the figure working state), pressurized air enters from air inlet 1, be dispensed to middle commutation valve body 2 through pilot valve valve body 8, reach main directed air valve body 3 again, main directed air valve spool 6 is dispensed to pressurized air the right air cavity 12 of the pump housing at last, when right air cavity 12 pressure surpass the liquid container pressure that barrier film tosses about, the hydraulic coupling of liquid container pushes back valve seat with pump housing entrance ball check valve, close liquor inlet, to export ball valve simultaneously and push away valve seat, open liquid outlet, liquid is extruded and is external from the water outlet excavationg pump, i.e. discharge opeing.
Induction stroke: the pressurized air of left air cavity 11 is dispensed to baffler 5 by main directed air valve spool 6, is drained in the air by baffler 5, and the volume of left air cavity 11 reduces, the liquid chamber volume that barrier film is tossed about increases, form vacuum, liquid chamber pressure reduces, when the atmospheric pressure in the external world during greater than liquid chamber pressure, generate pressure reduction, external atmospheric pressure promotes liquid through intake line, pump housing inlet side ball check valve is pushed away valve seat, liquid influent chamber, until filling up, i.e. suction.
The to-and-fro motion of pump: when barrier film is moved to certain position by barrier film connecting rod 10, barrier film contacts with the drive plunger 9 of pilot valve, barrier film promotes drive plunger 9 and continues motion, when barrier film connecting rod 10 and diaphragm movement during to the stroke end, drive plunger 9 drives pilot valve spool 7 and moves to another working state, after pilot valve spool 7 is activated, part pressurized air is by the air cavity pipeline that is dispensed to pilot valve of the air cavity pipeline process pilot valve spool 7 of pilot valve, reach the air cavity of middle commutation valve body through the air cavity pipeline of pilot valve, reach the C chamber 13 of main directed air valve body 3 again, after pressure signal is received in C chamber 13, the spool that activates main directed air valve is converted to another working state, the spool 6 of main directed air valve makes pressurized air reassign to the right air cavity 12 of the pump housing, begins draining.Air-breathing and the exhaust that pump housing air chamber replaces just forms imbibition and discharge opeing stroke that the pump liquid chamber replaces, and the continuous conveying of liquid medium is finished in motion so repeatedly.
