Abstract
The utility model discloses a kind of ball check valve for sewage discharge, including valve body and the ball float being arranged in valve body, the lower end of the valve body is provided with dirt inlet, upper end is provided with sewage draining exit, the middle part of the valve body at least opens up a pipeline connection port, the ball float side connected with the valve body is additionally provided with the side wall of the valve body and holds passage, holds in the ball float side at the port of passage and is provided with bonnet；The diameter of the ball float is more than the diameter of the dirt inlet and sewage draining exit, and the diameter of the ball float is less than the diameter that the ball float side holds passage.The utility model unique structure is novel, simple and practical, can realize sewage non-return, the purpose of multi-pipeline blowdown automatically, and manufacturing cost is low, service life length, suitable for being widely used in the fields such as multi-pipeline sewage discharge.
Description
Technical field
It the utility model is related to valve technology field, specifically a kind of ball check valve for sewage discharge.
Background technology
With the continuous development of industry, the discharge of sewage has turned into the necessary process of modern industry operation, and is arranged in sewage
Generally required when putting and use check-valves.Check-valves is also known as check valve or non-return valve, is one kind of Fluid valve, and it is applied to conveying
It can be played in pipe network and ensure that sewage flows through valve and prevent the function of medium reverse flow along positive.Structurally, non-return
Valve typically has the species such as swing type, lift, butterfly and spherical valve core plugging type, because the check-valves of spherical valve core plugging type opens
Close rapidly, it is safe for operation, it is widely used in transmission pipeline network.But check-valves is often fitted due to the characteristic of its pipeline at present
For one-in-and-one-out formula pipeline, and two or more pipelines are frequently necessary in sewage discharge industry while enter same pipe
Discharged again behind road, and the two or multiple pipelines can not be connected, this just needs to research and develop a kind of non-return of specific structure
Valve, which could be realized, ensures that sewage flows through valve and prevent the function of sewage reverse flow along positive.
Utility model content
The purpose of this utility model is just to provide a kind of ball check valve for sewage discharge, to solve existing check-valves
The problem of being unsuitable for two or more pipeline blowdowns and preventing sewage from flowing backwards simultaneously.
The purpose of this utility model is achieved through the following technical solutions：A kind of spherical non-return for sewage discharge
Valve, including valve body and the ball float being arranged in valve body, the lower end of the valve body is provided with sewage draining exit provided with dirt inlet, upper end, described
The middle part wall of valve body up to offers a pipeline connection port less, is additionally provided with the side wall of the valve body and connects with the valve body
Logical ball float side holds passage, holds in the ball float side at the port of passage and is provided with bonnet；The diameter of the ball float enters described in being more than
The diameter of dirty mouth and sewage draining exit, the diameter of the ball float are less than the diameter that the ball float side holds passage.
A pipeline connection port is offered on the middle part wall of the valve body；The pipeline connection port and the second sewage transport
Pipeline is connected, and second sewage running piping is connected with submersible sewage pump.
The utility model up to opens up a pipeline connection port less by the middle part wall in valve body so that check-valves can be with
Connect multiple sewage running pipings；The ball float side connected with the valve body set in the side wall of valve body holds passage and in ball float
Side hold passage port at set bonnet so that sewage from multiple one pipeline of pipeline flow-direction when, ball float floating to ball float side hold
In passage, the purpose discharged while sewage is realized.The utility model unique structure is novel, simple and practical, can realize automatically
Sewage non-return, the purpose of multi-pipeline blowdown, manufacturing cost is low, service life length, suitable in the fields such as multi-pipeline sewage discharge
Widely use.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model check-valves.
Fig. 2 is structural representation when the utility model check-valves uses.
Embodiment
Example below is used to the utility model be further described, but does not limit the utility model in any form.
Embodiment 1
As shown in figure 1, a kind of ball check valve for sewage discharge provided by the utility model, including valve body 1 and set
Put the ball float 2 in valve body 1.The lower end of its valve body 1 is provided with dirt inlet 3, upper end is provided with sewage draining exit 4, and the middle part of valve body 1 also opens up
There is a pipeline connection port 5, and the ball float side for being further opened with connecting with valve body 1 in the side wall of valve body 1 holds passage 6, in ball float
Side holds has screwed up bonnet 7 at the port of passage 6 by screw thread.The diameter of its ball float 2 is more than the diameter of dirt inlet 3 and sewage draining exit 4,
The diameter of ball float 2 is less than the diameter that ball float side holds passage 6.In use, the as shown in Fig. 2 sewage transport of pipeline connection port 5 and second
Pipeline 8 is connected, and conveyance conduit 8 is connected with submersible sewage pump 9.
In use, sewage is entered in valve body 1, in valve body 1 under the pressure effect of submersible sewage pump 9 by conveyance conduit 8
Ball float 2 falls into the top of dirt inlet 3 and stops dirt inlet 3, and sewage flows out from sewage draining exit 4；And when dirt inlet 3 also has sewage entrance
During valve body 1, ball float 2 holds at the bonnet 7 of the port of passage 6 under being acted in hydraulic pressure floating to ball float side, the sewage of dirt inlet 3 and latent dirt
The sewage that pump 9 is pumped into together is discharged from sewage draining exit 4.
The technical solution of the utility model and beneficial effect are described in detail above-described embodiment,
It should be understood that the foregoing is only most preferred embodiment of the present utility model, the utility model is not limited to, it is all at this
Any modification, supplement and equivalent substitution made in the spirit of utility model etc., should be included in guarantor of the present utility model
Within the scope of shield.
