Abstract
The utility model discloses a stepless display and water level control sensor which is characterized in that the casing fixed at the lower part in a water container is composed of a top cover and a base sealed with the top cover. An inlet opening is arranged on the base. The circumference of the membrane with corrugations is sealed with the wall of the inner cavity of the casing. The middle is corresponding to the inlet opening. A push rod and a spring abutting with the middle of the membrane support on the casing. The push rod is provided with an electrical resistance slice matched with a travelling arm. The electrical resistance slice is electrically connected with a water level display control device. The stepless display and water level control sensor can change the pressure variation of the water level measured into positional variation of the travelling arm on the electrical resistance slice. The electrical signal is transformed and is transmitted to the water level display control device by connecting wires. The stepless display and the stepless control for the smaller water-level fluctuation are realized. The use is very wide, such as the indicating and the control of the water level of a solar energy water container, the display control of the water level of a hot and cold water container of a bath, bathysondes of rivers, etanges, pumping wells, etc.
Description
Affiliated field
The utility model relates to a kind of liquid level sensor, especially is applied to the sensor of stepless demonstration of water level and control.
Background technology
Measuring the less water level of control amplitude of variation at present, as water tower, solar water heater etc., generally all is that water conductive electrode or tongue tube magnet assemblies are obtained measurement and control signal.The main drawback of water conductive electrode is that the easily ionizable polarization was lost efficacy.The main drawback of tongue tube magnet assemblies is owing to there is physical displacement, installs easy fatigue break, destroys leakproofness and loses efficacy.The two also has a common shortcoming is exactly to show control to limited water level point.When requiring to carry out multistage water level and show, will make sensor and signal wire become very numerous and diverse and lose practical value.
Summary of the invention
In order to overcome the shortcoming that above-mentioned technology exists, the purpose of this utility model is to provide a kind of variation based on water level principle that corresponding pressure changes to be arranged and design can realize stepless demonstration and control to less SEA LEVEL VARIATION to the sensitive level sensor of less SEA LEVEL VARIATION.
The technical solution of the utility model is, the housing that is fixed on bottom in the water receptacle is formed by loam cake with the base of loam cake sealing, base is provided with the inlet opening, the diaphragm that has gauffer seals with the housing internal chamber wall all around, the middle part is corresponding with the inlet opening, contacting with diaphragm middle part is provided with push rod and the spring that is supported on the housing, and push rod is provided with the resistor disc that cooperates with travelling arm, and this resistor disc is electrically connected with water level demonstration and control device.
Further scheme is, be provided with the mobile hole that cooperates with push rod last covering, spring places between loam cake inwall and the push rod head, the push rod end is provided with travelling arm, cooperate with travelling arm and to be provided with resistor disc, be provided with the seal box that contains travelling arm and resistor disc in the upper end of loam cake, lead connects resistor disc by seal box and water level shows and the control device.
Can also be, described push rod, spring, travelling arm and resistor disc be arranged on the housing inner chamber, cooperate the push rod support that is provided with the band through hole with push rod, and lead connects resistor disc by housing and water level shows and the control device.
The utility model beneficial effect is:
1, overcomes the polarization of water conductive electrode easily ionizable and lost efficacy, and caused the shortcoming of attachment short circuit for a long time inefficacy between electrode because of water quality inferiority.
2, can realize stepless demonstration and control to water level.
3, the sensor that utilizes this principle to make, purposes is very extensive, and such as the water level indication and the control of solar water container, the hot and cold water tank's of bathing pool water level shows control; Bathysondes such as river, pond, motor-pumped well etc.
Description of drawings
Figure is a main cut-open view of the present utility model.
Among the figure: 1 inlet opening, 2 ends seat, 3 diaphragms, 4 push rods, 5 springs, 6 loam cakes, 7 travelling arms, 8 resistor discs.
Embodiment
As shown in the figure, the technical scheme of present embodiment is, the housing that is fixed on bottom in the water receptacle is formed by loam cake 6 with the base 2 of loam cake sealing, base 2 is provided with inlet opening 1, the diaphragm 3 that has gauffer seals with the housing internal chamber wall all around, and the middle part is corresponding with inlet opening 1, contacts with diaphragm 3 middle parts to be provided with push rod 4 and the spring 5 that is supported on the housing, push rod 4 is provided with the variable resistive film 8 that cooperates with travelling arm 7, and this resistor disc 8 shows with water level and control device is electrically connected.
Loam cake 6 is provided with the mobile hole that cooperates with push rod 4, spring 5 places between loam cake inwall and the push rod head and is placed on the push rod 4, push rod 4 ends are provided with travelling arm 7, cooperate with travelling arm 7 and to be provided with resistor disc, be provided with the seal box that contains travelling arm 7 and resistor disc 8 in the upper end of loam cake 6, lead connects resistor disc 8 by seal box and water level shows and the control device.
Have water 1 importing from the inlet opening of certain pressure (height of water level), diaphragm 3 is produced pressure, diaphragm 3 promotes push rod 4 and produces displacements because of pressure produces deformation.5 pairs of push rods 4 of spring have a reacting force, in order to the pressure of equilibrium water, thereby make the displacement of push rod 4 change corresponding one by one with the pressure of water.Variable-resistance travelling arm 7 is housed at the top of push rod 4, this travelling arm 7 be fixed on the resistor disc 8 that covers and be in the sliding friction state, the pressure of tested water level has been become the variation of the position of travelling arm 7 on resistor disc 8, and be converted into electric signal and be transferred to water level by lead and show and the control device.
