Description
Technical field
the utility model relates to membrane pump with pneumatic drive, particularly relates to a kind of imbibition bottom valve.
Background technique
in the production of beverage, often need to use CIP cleaning station tank and pipeline are cleaned, sterilized.When CIP cleaning station allotment cleaning solution, need to reach chemical barrel by flexible pipe with membrane pump with pneumatic drive and add acid, alkali.In the process of membrane pump with pneumatic drive pumping acid, alkali, because membrane pump with pneumatic drive is to belong to pulsed drawing liquid, in imbibition process, can produce liquid backflow; In addition, in CIP cleaning process, diaphragm pump needs timing to add acid, alkali, need to be by ability pumping acid, alkali after complete the air pumping in flexible pipe, and the time of adding acid, alkali can be very long; In addition, membrane pump with pneumatic drive is to not filtering protection between chemical barrel, once be mixed with impurity in chemical product, easily membrane pump with pneumatic drive caused to damage.
Summary of the invention
the purpose of this utility model is to provide a kind of imbibition bottom valve for membrane pump with pneumatic drive.
for achieving the above object, the technical solution adopted in the utility model is:
a kind of imbibition bottom valve for membrane pump with pneumatic drive, there is a valve body, in described valve body, be provided with position-limiting tube and non-return piece, described non-return piece has tapered channel, described tapered channel and the pipeline of position-limiting tube are configured for the imbibition passage of imbibition, in described tapered channel, be provided with spheroid, described spheroid opens or closes described tapered channel.
preferably, the bottom of described imbibition passage is provided with at least one deck filter screen.
further preferably, to be provided with two-layer up and down, described upper strata filter screen be 60 order filter screens to described filter screen; The many filter screens of described lower floor are 40 order filter screens.
preferably, on described position-limiting tube, be provided with the back-up ring for limiting described spheroid movement position.
preferably, described valve body comprises upper valve body and lower valve body.
preferably, described spheroid is ceramic ball.
because technique scheme is used, the utility model compared with prior art has following advantages:
(1), simple in structure, be convenient to manufacturing;
(2), valve part can adopt the material of resistance to concentrated acid, concentrated base corrosion to make, without maintenance, change parts;
(3), profile is small and exquisite, can directly put in chemical barrel and use;
(4), with filtering function, can prevent that the impurity in acid, alkali from entering the pump housing in the time that diaphragm pump is worked, barrier film is caused to damage, extend working life of membrane pump with pneumatic drive.
Brief description of the drawings
accompanying drawing 1 is membrane pump with pneumatic drive drawing liquid flow chart;
the structure principle chart that accompanying drawing 2 is imbibition bottom valve.
wherein: 1, membrane pump with pneumatic drive; 2, pick-up tube; 3, chemical barrel; 4, imbibition bottom valve; 41, position-limiting tube; 42, back-up ring; 43, upper valve body; 44, ceramic ball; 45, non-return piece; 450, tapered channel; 46, lower valve body; 47,60 order filter screens; 48,40 order filter screens.
Embodiment
below in conjunction with drawings and Examples, the utility model is further described:
a kind of imbibition bottom valve for membrane pump with pneumatic drive as shown in Figure 1, 2, there is a valve body, in valve body, be provided with position-limiting tube 41 and non-return piece 45, non-return piece 45 has tapered channel 450, and the pipeline of tapered channel 450 and position-limiting tube 41 is configured for the imbibition passage of imbibition.In tapered channel 450, be provided with spheroid, adopt ceramic ball 44 herein, ceramic ball 44 opens or closes tapered channel 450.When the work of imbibition bottom valve, because the suction that membrane pump with pneumatic drive 1 produces is raised ceramic ball 44, tapered channel 450 is opened, and imbibition passage forms path, and the liquid in chemical barrel 3 is aspirated and be pumped into use point; In the time that membrane pump with pneumatic drive 1 stops aspirating, ceramic ball 44 can be because the gravity of self sets back, and contacts to form to seal the liquid refluence preventing in pick-up tube, thereby improve the efficiency of membrane pump with pneumatic drive 1 with non-return piece 45.
be provided with at least one deck filter screen in the bottom of imbibition passage, in the present embodiment, filter screen is provided with two-layer up and down, and upper strata filter screen is 60 order filter screens 47; The many filter screens of lower floor are 40 order filter screens 48; Two-layer filter screen can filter the impurity of sneaking in acid, alkali, prevents that impurity from entering membrane pump with pneumatic drive 1, thereby membrane pump with pneumatic drive has been carried out to protection 1.
on position-limiting tube 41, be provided with back-up ring 42, the effect of back-up ring 42 is movement positions of restriction ceramic ball 44, avoids the excessive pick-up tube that enters of suction to stop up circulation.
in addition, in the present embodiment, valve body comprises upper valve body 43 and lower valve body 46, and valve body is divided into processing and the installation that two parts are conducive to all parts.
when the present embodiment has solved and again started after the backflow that produces due to the drawing liquid mode of membrane pump with pneumatic drive self and membrane pump with pneumatic drive quit work, add the chronic of acid, alkali; And prevent that the impurity of sneaking in concentrated acid, concentrated base from causing damage to diaphragm pump.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
