Abstract
A kind of fluid level control device, is made up of water tank, plastics keg float, traction rope, fixed pulley, slideway, weight slide block, pointer, proximity switch and control loop; The plastics keg float of dress water is provided with in the water tank filling liquid, water tank one is edge-on slideway with a scale, slideway is slidably connected weight slide block, weight slide block is fixed with pointer, traction rope one end connects weight slide block, the other end is connected on plastics keg float after walking around fixed pulley, is provided with proximity switch outside slideway, and proximity switch is connected on the control loop of control system by wire.The utility model structure is simple, good airproof performance, failure rate is low, is easy to safeguard, buoyancy can regulate arbitrarily, liquid level reflection is true and reliable, and reading is intuitively simple, can realize liquid level conduction and be separated with control, reduce use cost, improve serviceable life, be particularly useful for unattended sunk type pump house automatic drain system, reach below setting warning line Auto-drainage to safe water bit line.
Description
Technical field
The utility model belongs to liquid level automatic balancing control device field, is specifically related to one and utilizes liquid buoyancy and non-contacting sensor, submersible pump or other water feeding and draining devices is carried out to the device of liquid level automatic balancing control.
Background technology
Level Control Technology is of a great variety, but substantially can be divided into two large classes, and a class is Analog control; Another kind of is discrete control.But all inevitable liquid level degree of depth to scene of which kind of control mode or kind of liquid, proportion etc. have such or such requirement, and most of integrated product, installation requirement, if add later maintenance, its use cost greatly and be difficult to control.
Summary of the invention
It is simple that the utility model aims to provide a kind of structure, good airproof performance, failure rate is low, is easy to safeguard, buoyancy can regulate arbitrarily, realizes liquid level conduction and is separated with control, can reduce the fluid level control device of use cost.
For this reason, the solution that the utility model is taked is:
A kind of fluid level control device, is characterized in that, be made up of water tank, plastics keg float, traction rope, fixed pulley, slideway, weight slide block, pointer, proximity switch and control loop; Liquid is filled in water tank, liquid upper is provided with the plastics keg float that is equipped with water, water tank one is edge-on slideway with a scale, slideway is slidably connected a metal weights slide block, weight slide block is fixed with pointer, and traction rope one end connects weight slide block, and the other end is turned back after walking around fixed pulley and is connected on plastics keg float, outside slideway, be provided with at least one proximity switch along slideway scale direction, proximity switch is connected on the control loop of control system by wire.
Control method of the present utility model and beneficial effect are:
Filled with water or other liquid buoyancy counterweight can be regulated in the utility model Plastic Drum, liquid level indicates and is made up of the metal weights of traction rope end and pointer, the change of liquid level can be reflected in the motion of vertical direction intuitively, liquid level display is made up of in conjunction with total indicator reading the content gauge demarcated in advance, and sensor is arranged on the motion track of weight slide block, slideway footing varying height positions.Liquid level change drives cursory moving up and down, and metal weights sensing is thereupon upper and lower moves along slideway planned orbit, as long as reserve Liquid level depth point according to actual needs, and proximity switch is arranged on corresponding position.
The utility model is by liquid level sensing device and control device physics and electrical isolation, effectively can improve the life-span, and can according to on-the-spot actual employing entirety or partial devices, with the use of corresponding proximity switch, cost elasticity is large, cost is controlled, be easy to safeguard, liquid level reflection is true and reliable, reading is intuitively simple, for operating environment without particular/special requirement, indoor outer, be particularly useful for unattended sunk type pump house automatic drain system, reach below setting warning line Auto-drainage to safe water bit line.
Accompanying drawing explanation
Fig. 1 is fluid level control device structural representation.
In figure: water tank 1, liquid 2, plastics keg float 3, traction rope 4, fixed pulley 5, slideway 6, scale 7, weight slide block 8, pointer 9, proximity switch 10, wire 11.
Embodiment
As seen from Figure 1, the utility model fluid level control device is mainly made up of water tank 1, plastics keg float 3, traction rope 4, fixed pulley 5, slideway 6, weight slide block 8, pointer 9, proximity switch 10 and control loop.Fill liquid 2 in water tank 1, above liquid 2, be provided with the plastics keg float 3 that is equipped with water.Found a slideway 6 with altitude scale 7 on the right side of water tank 1, slideway 6 footing varying height positions, slideway 6 is slidably connected a metal weights slide block 8, and weight slide block 8 can slide up and down along slideway 6.Weight slide block 8 is fixed with pointer 9, to show liquid level.Traction rope 4 one end connects weight slide block 8, and the other end is turned back after walking around fixed pulley 5 and is connected on plastics keg float 3, and be provided with 3 proximity switches 10 in the outside of slideway 6 along scale 7 direction, proximity switch 10 is connected on the control loop of control system by wire 11.
