Abstract
The utility model discloses check valves, including tube body, baffle is welded with above tube body, valve body is provided with above baffle, valve body is integrally welded with block, baffle is located among valve body and block, beneficial effect is: before water filling, this check valve valve body is closely buckled on baffle due to gravity, when water filling, hydraulic pressure jacks up valve body, since baffle and block limit valve body, valve body is set not fall off out of tube body, water purification simultaneously is injected in cabinet by the gap of valve body and baffle, after the completion of water filling, check valve valve body is closely buckled on baffle again due to gravity, play sealing function, the intracorporal water purification of case will not be flowed into water injection pipe from from baffle, backflow phenomena will not be generated, such design, so that the present apparatus is more stable, environmental protection, it is easy, it is safe and reliable.
Description
Technical field
The utility model relates to a kind of valves, in particular to check valve, belong to rolling stock plumbing sanitary equipment technology neck
Domain.
Background technique
In the prior art, the existing rolling stock clear water tanks inlet pipeline outlet in China is not provided with check valve, works as train
When acutely shaking, the water purification in case can be splashed into water outlet as cabinet fluctuates, and lead to have a large amount of waters in water injection pipe.Work as secondary injection
When water, water generates waste, so the utility model proposes check valves since gravity generates reflux.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides check valve.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
The utility model check valve, including tube body, the tube body top are fixedly connected with baffle, are arranged between the baffle
There is valve body, the lower end two sides that the valve body is located at tubular body are fixedly connected with several blocks.
As a kind of optimal technical scheme of the utility model, the baffle is ring baffle.
As a kind of optimal technical scheme of the utility model, the internal diameter of the baffle is greater than block top half width.
As a kind of optimal technical scheme of the utility model, the internal diameter of the baffle is less than block lower half portion width.
As a kind of optimal technical scheme of the utility model, the internal diameter of the tube body is greater than block lower half portion width.
As a kind of optimal technical scheme of the utility model, the block top half is connected among baffle by perforation
It connects.
The utility model beneficial effect achieved is: before water filling, this check valve valve body is closely buckled in baffle due to gravity
On, when water filling, hydraulic pressure jacks up valve body, since baffle and block limit valve body, take off valve body will not out of tube body
It falls, while water purification is injected in cabinet by the gap of valve body and baffle, after the completion of water filling, check valve valve body is due to gravity again
It is closely buckled on baffle, plays sealing function, the intracorporal water purification of case will not be flowed into water injection pipe from from baffle, will not generate inverse
Flow phenomenon, such design, so that the present apparatus is more stable, environmentally friendly, easy, safe and reliable.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the utility model sectional view；
Fig. 3 is the structural schematic diagram of the utility model off working state；
Fig. 4 is utility model works status architecture schematic diagram；
Fig. 5 is the mounting structure schematic diagram of the utility model.
In figure: 1, valve body；2, baffle；3, tube body；4, block.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
As shown in Figs. 1-5, check valve, including tube body 3 are welded with baffle 2 above tube body 3, are provided with valve body above baffle 2
1, valve body 1 and block weldering 4 are connected into one, baffle 2 be located at valve body 1 among block 4, after the completion of water filling, the valve body 1 of the present apparatus because
Gravity is closely buckled in again on baffle 2, plays sealing function, and the intracorporal water purification of case will not be flowed into water filling from baffle 2
Guan Zhong will not generate backflow phenomena.
Baffle 2 is ring baffle, and the internal diameter of baffle 2 is greater than 4 top half width of block, and the internal diameter of baffle 2 is less than block 4
The internal diameter of lower half portion width, tube body 3 is greater than 4 lower half portion width of block.4 top half of block is among baffle 2 by wearing
Hole connection.
Specifically, when the utility model is used, before water filling, valve body 1 is closely buckled on baffle 2 this check valve due to gravity,
When water filling, hydraulic pressure jacks up valve body 1, since baffle 2 and block 4 limit valve body 1, makes valve body 1 will not be out of tube body 3
It falls off, while water purification is injected in cabinet by the gap of valve body 1 and baffle 2, after the completion of water filling, the valve body 1 of the present apparatus is because of gravity
Effect is closely buckled in again on baffle 2, plays sealing function, and the intracorporal water purification of case will not be flowed into water injection pipe from baffle 2,
Backflow phenomena, such design will not be generated, so that the present apparatus is more stable, environmentally friendly, easy, safe and reliable.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
