Generation error or drive rod are stuck and cause its deflection angle constant, cause the signal inaccuracy of fluid level controller.
Utility model content
To solve the above-mentioned problems, the purpose of the utility model is to provide a kind of Liquid level machines of sewage lifting device
Structure, to solve the problems, such as that existing level controling mechanism is easily interfered by the impurity in sewage.
Based on this, the utility model provides a kind of level controling mechanism of sewage lifting device, including diaphragm pressure becomes
Device and the device for storing liquid with accommodating chamber are sent, the diaphragm pressure transmitter has the measuring diaphragm being set in its liquid feeding end,
The diaphragm pressure transmitter is set on the side wall of the device for storing liquid and the liquid feeding end of the diaphragm pressure transmitter is connected to
The accommodating chamber, the measuring diaphragm and the liquid level in accommodating chamber are perpendicular.
Preferably, the central axis of the liquid feeding end of the diaphragm pressure transmitter is in the measuring diaphragm.
Preferably, further including the filter device in the accommodating chamber, the purification end connection of the filter device
In the liquid feeding end of the diaphragm pressure transmitter.
Preferably, the filter device is mesh enclosure made of stainless steel.
Preferably, mounting hole is offered on the side wall of the device for storing liquid, the feed liquor of the diaphragm pressure transmitter
End penetrates the mounting hole, and the diaphragm pressure transmitter is removably attachable to the device for storing liquid.
Preferably, the diaphragm pressure transmitter is located at the lower end of the device for storing liquid.
Preferably, the lower end of the device for storing liquid, which is equipped with, is connected to the accommodating chamber extraneous exhaust-valve.
The side wall of the level controling mechanism of the sewage lifting device of the utility model, device for storing liquid becomes equipped with diaphragm pressure
Device is sent, diaphragm pressure transmitter has the measuring diaphragm being set in its liquid feeding end, and the liquid feeding end connection of diaphragm pressure transmitter
The liquid feeding end of diaphragm pressure transmitter is passed through in the sewage in accommodating chamber, accommodating chamber and squeezes measuring diaphragm, measures film
The pressure that piece applies it according to sewage is to confirm liquid level information, since measuring diaphragm and the liquid level in accommodating chamber are perpendicular, because
Impurity in this sewage can not be deposited on measuring diaphragm, and the impurity of precipitating is avoided to generate interference to measuring diaphragm.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the level controling mechanism of the sewage lifting device of the utility model embodiment；
Fig. 2 is that the device for storing liquid partial structurtes of the level controling mechanism of the sewage lifting device of the utility model embodiment are shown
It is intended to.
Wherein, 1, diaphragm pressure transmitter；11, liquid feeding end；2, device for storing liquid；21, mounting hole；3, filter device；4, it arranges
Empty valve.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Referring to figs. 1 and 2, the Liquid level machine of the sewage lifting device of the utility model is schematically showed
Structure, the device for storing liquid 2 including diaphragm pressure transmitter 1 and with accommodating chamber.Diaphragm pressure transmitter 1, which has, is set to its feed liquor
Measuring diaphragm in end 11, the central axis of the liquid feeding end 11 of diaphragm pressure transmitter 1 is in the measuring diaphragm, measuring diaphragm
Height of liquid level is judged by perceiving the pressure that liquid generates it.Diaphragm pressure transmitter 1 is set on the side wall of device for storing liquid 2
And the liquid feeding end 11 of diaphragm pressure transmitter 1 is connected to accommodating chamber, the sewage in accommodating chamber enters diaphragm pressure by liquid feeding end 11
Power transmitter 1, the hydraulic pressure that measuring diaphragm is applied by sewage and the height of liquid level for detecting sewage.Due to measuring diaphragm and accommodating chamber
Interior liquid level is perpendicular, and the measurement accuracy for avoiding the contamination precipitation in sewage from leading to measuring diaphragm on measuring diaphragm reduces.
Diaphragm pressure transmitter 1 is located at the lower end of device for storing liquid 2, to maximize the level sensing of diaphragm pressure transmitter 1 as much as possible
Range.The lower end of device for storing liquid 2, which is equipped with, is connected to accommodating chamber extraneous exhaust-valve 4, when needing to overhaul accommodating chamber,
The sewage in accommodating chamber can be discharged by exhaust-valve 4 and empty accommodating chamber.
Impurity to further avoid in sewage enters in diaphragm pressure transmitter 1, the filter device 3 in accommodating chamber, mistake
The purification end of filter device 3 is connected to the liquid feeding end 11 of diaphragm pressure transmitter 1, it is preferred that filter device 3 is made of stainless steel
Mesh enclosure, mesh enclosure be located in the liquid feeding end 11 of diaphragm pressure transmitter 1, so that biggish impurity can not be with measuring diaphragm phase in sewage
Contact, does not influence the pressure precision of measuring diaphragm, moreover, mesh enclosure uses stainless bracing members, it is ensured that mesh enclosure is not easily susceptible to sewage
Corrosion.
For the ease of dismounting diaphragm pressure transmitter 1, such as Fig. 2, mounting hole 21 is offered on the side wall of device for storing liquid 2, every
The liquid feeding end 11 of membrane pressure power transmitter 1 penetrates mounting hole 21, and the liquid feeding end 11 is stretched out by mounting hole 21 from the inner wall of accommodating chamber,
Diaphragm pressure transmitter 1 is removably attachable to device for storing liquid 2 by fasteners such as bolts.
In conclusion the level controling mechanism of the sewage lifting device of the utility model, the side wall of device for storing liquid 2 is equipped with
Diaphragm pressure transmitter 1, diaphragm pressure transmitter 1 have the measuring diaphragm being set in its liquid feeding end 11, and diaphragm pressure pick-up
The liquid feeding end 11 of device 1 is connected to accommodating chamber, and the sewage in accommodating chamber is passed through the liquid feeding end 11 of diaphragm pressure transmitter 1 and makes to measure
Diaphragm is squeezed, and the pressure that measuring diaphragm applies it according to sewage due to measuring diaphragm and is accommodated with confirming liquid level information
Intracavitary liquid level is perpendicular, therefore the impurity in sewage can not be deposited on measuring diaphragm, avoids the impurity of precipitating to measurement film
Piece generates interference.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change
