The right end for the U-tube stated is equipped with check valve body, and the check valve body band is magnetic, and the lower section of the check valve body is equipped with down
Magnetite frame, the lower magnetite frame are fixed on the outer surface of U-tube, and magnetite, the magnetic are equipped in the lower magnetite frame
Stone and lower magnetite frame releasable connection.
It as a further improvement of the above technical scheme, further include upper magnetite frame, the upper magnetite frame is fixed on unidirectionally
The top of valve body, the upper magnetite frame are fixed on the outer surface of U-tube.
It as a further improvement of the above technical scheme, further include alarm device, the alarm device includes light inductance
Device is answered, the photoelectric induction device includes transmitter and receiver, and the transmitter and receiver are separately fixed at sky
The two sides of air column, the oblique lower section setting of the transmitter, the receiver are fixed on along the direction of transmitter meaning.
The beneficial effects of the invention are as follows:By be arranged check valve, when the pressure of input terminal it is small compared with when, liquid level will not be caused
It influences, so that the fluctuation of liquid level is smaller, is more convenient for reading.Except, the mode that the technical program uses magnetic force to attract is check valve
Body provides sealing force, provides sealing force using the mode that spring presses compared to tradition for check valve body, only needs when adjusting pressure
It takes or adjusts the sealing force that can eliminate or change the check valve body set on magnetite on the outside of pipeline away, pass through knob compared to traditional

Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described.Obviously, described attached drawing is a part of the embodiments of the present invention, rather than is all implemented
Example, those skilled in the art without creative efforts, can also be obtained according to these attached drawings other designs
Scheme and attached drawing.
Fig. 1 is the structural schematic diagram of the embodiment of the present invention;
Fig. 2 is the light refraction schematic diagram of the embodiment of the present invention.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to design of the invention, specific structure and generation clear
Chu is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of the embodiment, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art are not being paid
Other embodiments obtained, belong to the scope of protection of the invention under the premise of creative work.In addition, be previously mentioned in text
All connection/connection relationships not singly refer to that component directly connects, and referring to can be added deduct according to specific implementation situation by adding
Few couple auxiliary, to form more preferably coupling structure.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
Embodiment is as follows, and referring to Figures 1 and 2, one kind is U-shaped to show that pressure pipe, including U-tube 1, the U-tube 1 are provided with liquid
Body, the left end of the U-tube 1 is closed end, right end is input terminal, and air column is equipped in the closed end;Described is U-shaped
The right end of pipe 1 is equipped with check valve body 2, and 2 band of check valve body is magnetic, and the lower section of the check valve body 2 is equipped with lower magnetic
Stone frame 4, the lower magnetite frame 4 are fixed on the outer surface of U-tube 1, and magnetite is equipped in the lower magnetite frame 4, described
Magnetite and lower 4 releasable connection of magnetite frame.
By be arranged check valve, when the pressure of input terminal it is small compared with when, liquid level will not be impacted, thus the fluctuation of liquid level
It is smaller, it is more convenient for reading.Except, the mode that the technical program uses magnetic force to attract provides sealing force for check valve body, compared to biography
System provides sealing force using the mode that spring presses for check valve body, only need to take away or adjust outside pipeline when adjusting pressure
The sealing force of the check valve body can be eliminated or be changed to side magnetite, compared to traditional by way of knob adjustment spring elastic force,
It is to maintain sealing inside its pipeline, leakage path, good airproof performance is not present;On the other hand, internal only to place one unidirectionally
Simultaneously a caliber is arranged compared with segment in valve body, and structure is simple, production easy to process.It is single furthermore when negative pressure occurs in input terminal
It can be avoided the liquid in U-tube to valve to be sucked away, to influence the instruction function to pressure.
It is further used as preferred embodiment, further includes upper magnetite frame 3, the upper magnetite frame 3 is fixed on check valve
The top of body 2, the upper magnetite frame 3 are fixed on the outer surface of U-tube 1.As a result, by taking the magnetite on lower magnetite frame
It walks to be installed on magnetite frame, check valve body can be made to stay open, U-tube is connected to input terminal, consequently facilitating more
Change internal liquid etc..
It is further used as preferred embodiment, further includes alarm device, the alarm device includes optoelectronic induction dress
It sets, the photoelectric induction device includes transmitter 5 and receiver 6, and the transmitter 5 and receiver 6 are separately fixed at sky
The two sides of air column, the oblique lower section of transmitter 5 setting, the receiver 6 are fixed on the direction signified along transmitter 5
On.By the way that alarm device is arranged, when its pressure value exceeds safe range, extraneous progress manual intervention can be notified in time,
It is unexpected to prevent occurring.The oblique lower section setting of transmitter in photoelectric induction device, thus when liquid level rises, the light of transmitting with
Certain angle is slanted through liquid level, existing by the way that deviation can occur known to the refraction principle of light when light injects liquid from air
As, so that light deviates receiver, the photosignal at receiver changes, start alarm device, thus liquid level
Height change can convert electric signal.It is compared using such mode and transmitter is horizontally disposed with and floating material is set on liquid level
Mode, its reliability is high, and deflection phenomenon can occur when liquid level rises the former light channel of influence, and uses the side of setting floating material
Formula, if blank phase of the floating material in its receiver detection cycle has passed through detection line, pressure exceeds safe range for nothing
Method perception, will cause security risk.
Better embodiment of the invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make various equivalent modifications on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
