Abstract
A kind of connection structure of membrane pump feeding pipe and clack box is related to a kind of improvement of the connection structure of membrane pump feeding pipe and clack box.The utility model offer is a kind of simple in structure, can extend charging clack box service life, and reduces the connection structure of membrane pump feeding pipe and clack box that abnormal sound is produced in diaphragm pump operational process.The utility model includes the gradually increase of the distance between feed pipe, the first charging clack box, the second charging clack box and the 3rd charging clack box, the first charging clack box, the second charging clack box and the feed inlet of the 3rd charging clack box and feed pipe, it is characterised in that：The first connecting tube being connected with the first charging clack box is provided with the feed pipe, the second connecting tube being connected with the second charging clack box and the 3rd connecting tube being connected with the 3rd charging clack box；The diameter of first connecting tube is more than the diameter of the second connecting tube, and the diameter of the second connecting tube is more than the diameter of the 3rd connecting tube.
Description
Technical field
It the utility model is related to a kind of improvement of the connection structure of membrane pump feeding pipe and clack box.
Background technology
Nowadays diaphragm pump is widely applied to the industries such as coal chemical industry.Valve cone, valve seat, membrane are diaphragm pumps as vulnerable part
Main consumables.Their service life directly concerns the actual production progress of the daily maintenance of diaphragm pump and factory.
The fed version of diaphragm pump is substantially all using unilateral charging, and existing diaphragm pump is as shown in Fig. 2, its feed pipe leads to
Threeway is crossed with charging clack box to be connected.Found by long-time service, diaphragm pump is during continuous operation, the valve away from feed inlet
Case always produces the phenomenon of slurry deposition, causes suction insufficient, so as to cause the phenomenon of valve cone interim card（Card valve）, seriously affect
Valve cone, the service life of valve seat and with larger abnormal sound.Chamber of septum suction deficiency is also easy to the rupture for causing membrane at the same time.
The content of the invention
The utility model is aiming at the above problem, there is provided and it is a kind of simple in structure, charging clack box service life can be extended, and
And reduce the connection structure of membrane pump feeding pipe and clack box that abnormal sound is produced in diaphragm pump operational process.
In order to realize the above-mentioned purpose of the utility model, the utility model adopts the following technical solution, the utility model bag
Include feed pipe, the first charging clack box, the second charging clack box and the 3rd charging clack box, the first charging clack box, the second inlet valve
The gradually increase of the distance between case and the feed inlet of the 3rd charging clack box and feed pipe, it is characterised in that：Set on the feed pipe
Be equipped with first the first connecting tube for being connected of charging clack box, the second connecting tube being connected with the second charging clack box and with the 3rd charging
The 3rd connecting tube that clack box is connected；The diameter of first connecting tube be more than the second connecting tube diameter, the second connecting tube it is straight
Footpath is more than the diameter of the 3rd connecting tube.
As a kind of preferred solution of the utility model, the end of the feed pipe is provided with closure flange.
The beneficial effects of the utility model：The utility model using gradually reduce connecting tube caliber structure type, i.e., from
Feed end starts, and charging latus rectum is from the close-by examples to those far off gradually reduced.This structure increases the slurry flow rate that charging distal end feeds clack box, subtracts
Lack slurry deposition, ensure that the suction flow of clack box and chamber of septum.So as to reducing card valve phenomenon, extend valve cone, valve seat,
The service life of membrane.
In addition, the utility model is provided with closure flange, set easy to be cleared up feed pipe or increased other auxiliary
Apply.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the connection structure of existing membrane pump feeding pipe and clack box.
1 it is feed pipe in attached drawing, 2 be the first connecting tube, 3 be the second connecting tube, 4 be the 3rd connecting tube, 5 is plugging method
It is blue, 6 for the 3rd charging clack box, 7 be the second charging clack box, 8 be the first charging clack box.
Embodiment
The utility model includes feed pipe 1, first and feeds the charging charging clack box 6 of clack box 7 and the 3rd of clack box 8, second, described
First charging clack box 8, second feeds the distance between feed inlet of the charging clack box 6 of clack box 7 and the 3rd and feed pipe 1 and gradually increases
Add, it is characterised in that：The first connecting tube 2 being connected with the first charging clack box 8 is provided with the feed pipe 1, with the second charging
The second connected connecting tube 3 of clack box 7 and the 3rd connecting tube 4 being connected with the 3rd charging clack box 6；First connecting tube 2 it is straight
Footpath is more than the diameter of the second connecting tube 3, and the diameter of the second connecting tube 3 is more than the diameter of the 3rd connecting tube 4.
As a kind of preferred solution of the utility model, the end of the feed pipe 1 is provided with closure flange 5.
The feed pipe 1 can be connected by pipe connections such as multiple-pass joint, elbows with connecting tube.
It is understood that above with respect to the specific descriptions of the utility model, it is merely to illustrate the utility model and is not
The described technical solution of the utility model embodiment is limited to, it will be understood by those of ordinary skill in the art that, still can be with
Modify to the utility model or equivalent substitution, to reach identical technique effect；As long as satisfaction uses needs, all in this reality
Within new protection domain.
