Background technology
Diaphragm pump also known as controls pump, is the main Types of actuator, the control signal exported by receiving modulation unit, and
It goes to change fluid flow by power operation, and in diaphragm pump in application, the flow direction of liquid can be controlled equipped with valve body thereon.
Traditional is mostly two balls or four ball diaphragm pumps, and two balls are single diaphragm pump, and four balls are twin-diaphragm pump, and diaphragm pump is close
The pulse that blocking movement generates is to influence the weight factor of membrane pumping function, and in four ball diaphragm pumps, the pulse that four balls generate must
The commutation of twin-diaphragm pump can so be had an impact.
Meanwhile existing diaphragm pump uses Multipoint assembling, installing and dismounting is more difficult, and is fluid passage on the outside of membrane,
It is gas on the inside of membrane, such reversal valve must be integrated on diaphragm pump.
The content of the invention
The present invention is to solve the above problems, provide a kind of three ball diaphragm pump of composite shaft, and it is reasonable to be designed in structure, outlet end
It is sealed using single ball, is different from four traditional ball twin-diaphragm pumps, more can efficiently carry out commutation sealing, reduce pulse, meanwhile,
Commutation can be external by solenoid valve, realizes remote control.
The present invention uses compound axostylus axostyle simultaneously, is different from traditional single shaft, and axostylus axostyle be both the fixed link covered partially and
The moving lever of commutation saves production cost.
In order to achieve the above objectives, the technical solution adopted by the present invention is：A kind of three ball diaphragm pump of composite shaft, including diaphragm pump
Body, the membrane of both sides and outermost inclined lid, further include axostylus axostyle, axostylus axostyle center by the diaphragm pump body, membrane,
Lid three, which connects, partially fixes；
Axostylus axostyle is compound axostylus axostyle, including inner shaft and outer shaft；Outer shaft is flexibly connected in diaphragm pump body central position, and outer shaft can be
It slides in inner shaft, and is connected at the nearly inner shaft in outer shaft both ends with diaphragm seal；Inner shaft both ends are equipped with screw thread, and axostylus axostyle inner hollow,
And gas outlet is equipped in membrane outer end, nut is revolved with screw thread and will covered partially, membrane and diaphragm pump body three are tightly connected, inner shaft
Both ends are connected with reversal valve, which is air operated reversing valve or solenoid valve；
Diaphragm pump body both sides are symmetrical chamber disk, are equipped with liquid-inlet on the downside of symmetrical chamber disk, upside is equipped with liquid
Body exports, and the liquid-inlet of both sides is connected with double ball feed liquor ball valve seats on the downside of it, and single ball is then equipped on the upside of diaphragm pump body
Go out liquid ball valve seat.
Further, left inlet and right inlet being equipped on the upside of double ball feed liquor ball valve seats, front end is additionally provided with total inlet,
Left inlet is connected with the left liquid-inlet in liquid-inlet, and accesses left chamber's disk in chamber disk, right inlet and liquid
Right liquid-inlet connection in import, and access the right chamber disk in chamber disk；
Further, single ball, which goes out, is equipped with left liquid outlet and right liquid outlet on the downside of liquid ball valve seat, upside is equipped with total liquid outlet, San Zhelian
It is logical, and be equipped with ball sealer in connectivity part and move back and forth slot, left liquid outlet is connected with the left liquid outlet in liquid outlet, thus with
Left chamber's disk connection, right liquid outlet is connected with the right liquid outlet in liquid outlet, so as to be connected with right chamber disk；
Further, the first ball sealer and the second ball sealer are respectively equipped in left inlet and right inlet, ball sealer is back and forth transported
The 3rd ball sealer is equipped in dynamic slot.
Further, it is equipped with bumping post in left liquid-inlet and right liquid-inlet.
Further, membrane is two-layer compound diaphragm, and inside is rubber layer, and outside is Teflon layer, is set between the two
There is nylon wire.
Further, diaphragm edge has a chamfering end of thread, and when lid is connected locking with diaphragm pump body partially, chamfering end of thread can be complete
Into sealing, and ensure the edge locking of membrane.
Further, it is equipped with holding force gasket between nut and inclined lid.
Further, sealing is completed using sealing ring or gasket seal at sealed connection.
Further, double ball feed liquor ball valve seat lower ends are additionally provided with external fixed pedestal.
When in use, liquid is out of total inlet import double ball feed liquor ball valve seats, then in reversal valve for this three ball diaphragm pump
Or under the action of solenoid valve, can from diaphragm pump body make surging disk or right chamber disk enters single ball and goes out liquid ball valve seat
It is interior, and in lid ball valve seat, ball valve is different from conventional ball valve, single ball design, the two-way open and close of control ball valve seat are controlled
The discharge of left chamber's disk or the discharge of right chamber disk processed, so as to which liquid is discharged from total liquid outlet.
Reversal valve uses air operated reversing valve, therefore this diaphragm pump can be applied to the dangerous liquids industry such as chemical industry, such as
The conveying of coal mine sewage, and reversal valve use solenoid valve when, then can with remote-controlled gas, realize commutation.
In conclusion valve seat of the present invention is integrally formed, it is reasonable to be designed in structure, meanwhile, the twin-diaphragm pump difference of three balls
In four traditional ball twin-diaphragm pumps, commutation sealing more can be efficiently carried out, reduces pulse, and this diaphragm pump overall cost
It is low, the dangerous industry such as chemical industry is can be applied to, and commutation can be external by solenoid valve, realizes remote control.
The present invention uses compound axostylus axostyle simultaneously, is different from traditional single shaft, and axostylus axostyle be both the fixed link covered partially and
The moving lever of commutation saves production cost.
