Abstract
The utility model relates to a liquid level meter, which belongs to a liquid level measuring device. The utility model comprises a supporting seat, wherein, a shell body is fixed on the supporting seat; a movable indicating needle is fixed on the shell body. The utility model is characterized in that gears of the indicating needle are engaged with racks arranged on a frame; springs are respectively arranged between a supporting frame of the shell body and a bearing plate, and between the bearing plate and the frame; the bottom end of the frame is connected with a floating cylinder by a connecting rod. The utility model has the characteristics of simple structure, high safety, etc.
Description
The utility model is to belong to liquid level emasuring device.
Be used for the fluid level measuring instrument of oil, chemical industry and sewage at present and have multiple, for example: 1, noncontact instrument: generally be installed on the liquid level top, in the emission of various ripples and reflection main mode as measurement, owing to contain in the crude oil and be easy to the hydrocarbons that volatilizees in a large number, particularly under heating condition, the speed of volatilization is very fast, makes to transmit and receive sensor and adhere to this class material very soon, causes instrument to lose efficacy; 2, immersible apparatus: owing to contain a certain proportion of moisture content in the crude oil, when the water cut in the crude oil reach 65% or moisture content through sedimentation when becoming free water, changes in capacitance produces distortion, causes instrument to lose efficacy; 3, surface contact: this device must change with liquid level variation, belongs to traverse measurement, because the bonding of paraffin and pitch can cause the malfunctioning of moving-member.
More than various metering systems also have a common characteristic, become the purpose that electric signal reaches measurement by physical quantity exactly.Probe in oil tank all is charged.This just need carry out encapsulation process to the electronic component in the probe, and whole device is carried out electrostatic prevention and explosion-proof protection, makes its complicated originally structure more complicated, has strengthened cost of manufacture, makes maintenance increase difficulty simultaneously.
The purpose of this utility model just provides a kind of simple in structure, liquid level gauge that performance is safe and reliable.
The purpose of this utility model is achieved in that the utility model comprises on bearing, the bearing and is fixed with housing, be fixed with movably pointer on the housing, its structural feature is that the gear of pointer is meshed with the tooth bar on the framework, the bracing frame of housing is with between the supporting plate, be respectively arranged with spring between supporting plate and the framework, the bottom of framework links to each other with floating drum by connecting rod.
Major advantage of the present utility model:
1, simple in structure:
The utility model main member is framework, spring, gear, tooth bar, floating drum, and its member is few, and body is simple, is easy to make convenient for maintaining;
2, safe and reliable:
The utility model does not adopt electronic original part, and adopts reliable machinery parts in addition, has therefore guaranteed safety, stable operation.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:
The utility model comprises bearing 4, be fixed with housing 18 on the bearing 4, be fixed with rotating pointer 12 on the housing 18, the gear 11 of pointer 12 is meshed with the tooth bar on the framework 8 10, the bracing frame 16 of housing 18 is with between the supporting plate 13, be respectively arranged with spring 15, spring 9 between supporting plate 13 and the framework 8, and the bottom of framework 8 links to each other with floating drum 2 by connecting rod 5.
For easy to use, connecting rod 5 can be divided into connecting rod 7, lower link 3, and last connecting rod 7, lower link 3 are connected with bolt 6 forms.
The top of bracing frame 16 is provided with adjusts bolt 17, can set up the distance of framework 8 operations.
During use, bearing 4 is fixed on the fixedly oil tank 1 of measured object, floating drum 2 is put into the liquid 19 of oil tank 1, the upstream or downstream owing to the variation of the buoyancy in the floating drum 2 suffered oil tanks 1,10 of the tooth bars of framework 8 move thereupon, gear 11 drives pointer 12 and rotates, and promptly just represents the amount of liquid 19 in the oil tank 1 with pointer 12.
