Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in the figure, the check valve with the built-in gas meter pipeline interface comprises a check valve body, a valve plate 6, a rotary connecting mechanism 5, a magnet I7 and a magnet II 8; the check valve body consists of a valve seat 3 and a valve sleeve 4, a valve plate 6 is assembled in the valve seat 3 through a rotary connecting mechanism 5 to block an inner cavity of the valve sleeve 4, and a magnet I7 is embedded in the lower part of the valve plate 6; a magnet II 8 is embedded in the bottom plane of the valve seat 3, and the magnet II 8 corresponds to a magnet I7 at the lower part of the valve plate 6.
In order to ensure the stability of the structure of the utility model, the valve plate 6 is in a disc shape, the outer diameter of the valve plate is larger than the hollow inner cavity of the valve sleeve 4, and a one-way plug is formed in the direction from the valve seat 3 to the valve sleeve 4.
In order to further ensure the stability of the structure, the magnetic poles on the opposite sides of the magnet I7 and the magnet II 8 are attracted in the same polarity, and are N poles or S poles.
In order to optimize the structural stability of the gas meter, the check valve body is a hollow stepped cylinder, a shaft shoulder is formed between the valve seat 3 and the valve sleeve 4 and pressed in an inner cavity of the gas meter 1, and the check valve body is embedded in the pipeline interface 2 of the gas meter 1 through the valve sleeve 4.
As a conventional technical option, the rotary connection mechanism 5 is a detachable rotary shaft structure.
In order to optimize the rotating shaft structure, the rotating shaft structure of the rotating connecting mechanism 5 is a hinge.
The working principle of the utility model is as follows:
the check valve body in the hollow step shape consists of a valve seat and a valve sleeve, and a valve plate is arranged on the valve seat to form unidirectional plugging in the direction from the valve seat to the valve sleeve.
Magnets with the same magnetic poles are embedded on the valve plate and the valve seat, and the valve plate and the valve seat are mutually closed by utilizing the principle that the magnets are attracted by the same polarities, so that the valve plays a role in blocking the valve and prevents water from flowing back; when the pipeline interface is introduced with gas with pressure, the valve plate is flushed by the gas flow, and the gas meter enters a working state.
When the valve is normally used, the valve plate can be pushed open by the gas pressure; when water flows downwards, the valve plate can directly cover the valve seat, and water in the wall-mounted furnace is prevented from flowing back to the gas pipeline.
The utility model has the characteristics that:
because the valve plate is arranged on the valve seat to form the unidirectional plugging in the direction from the valve seat to the valve sleeve, when water flows downwards on the valve seat, the valve plate can directly cover the valve seat to play a role in stopping and sealing, and the water in the wall-mounted furnace is prevented from flowing back to a gas pipeline to influence the safe operation of a pressure regulating facility and cause the danger of ice plugging.
Because the valve block is the same with the magnetic pole of the magnet inlaid on the valve seat, when the valve block covers the valve seat, the valve block and the valve seat plane are automatically closed mutually, and the air tightness of the inner cavity of the gas meter is kept.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
