Abstract
The utility model belongs to the technical field of water level automatic control, and provides a double-floating-ball type water level measuring device. The double-floating-ball type water level measuring device is mainly characterized by comprising a water tank, wherein a support frame with a support rod arranged at the upper end is arranged on the water tank, and a travel switch is arranged at the lower end of the support frame. A regulating nut is arranged on the support rod, a spring is connected between the regulating nut and the corner wall of the travel switch, and the junction of the corner wall of the travel switch and the spring is connected with an upper floating ball and a lower floating ball which are connected through a connecting line, and a travel switch high-low limitation output circuit is connected with an electrical automatic control system. The double-floating-ball type water level measuring device can measure a water level reliably and provide a control limitation value for the automatic control system, and meanwhile has the advantages of being simple in structure, convenient to maintain, low in investment, and high in reliability.
Description
Technical field
The utility model belongs to water level automatic control technology field, relates to a kind of pair of float-ball type level measurement device.
Background technology
Recirculated water is the important heat eliminating medium of afterheat generating system, the water yield of keeping the pond is stable, it is significant for keeping steam turbine cooling system to avoid occurring significantly water-level fluctuation, in the production and application process, for the water quality that keeps recirculated water need to be carried out necessary blowdown, consider that simultaneously the sharp draft cooling tower can cause certain water loss, must carry out moisturizing to circulating water pool, keep stable level, this just requires level measurement device simple and reliable, easy to maintenance, so that personnel monitoring's water level and provide reliable action limit value for automatic control loop.At present, at the process of using multiple mechanical type, the pressure type level measurement devices of adopting, all there is poor reliability in these devices more, and maintenance is frequent, the technical matterss such as inconvenient maintenance.
Summary of the invention
The inventor is in the daily course of work, find that existing cement kiln residual heat generating circulating water pool level measurement device exists defects, through design improvement constantly, technical problem to be solved in the utility model provide a kind of safe, convenient, reliably can provide for automatic control system again two float-ball type level measurement devices of control limit.
For solving the problems of the technologies described above, technical solution adopted in the utility model is that this pair float-ball type level measurement device comprises a pond, establish the upper end with the support of support bar in the pond, establish travel switch in the support lower end, establish adjusting nut at support bar, be connected with a spring between wall turning of adjusting nut and travel switch, the wall that turns at travel switch is connected with upper floating ball and the lower ball float that is connected by connecting line with the intersection of spring, and the spacing output loop of travel switch height is connected with automatic electrical control system.
Can immerse in the water in order to ensure lower ball float, described lower ball float density should be greater than the density of water.
The utility model adopts the designed two float-ball type level measurement devices of technique scheme, two float-ball type level measurement devices are set on the basis of original water replanishing device and are connected with corresponding automaton, can realize the automatic water supplement of circulating water pool, have safety, convenient, reliable advantage, can reduce hand labor intensity simultaneously.
Description of drawings
Fig. 1 represents the structural representation of the two float-ball type level measurement devices of the utility model.
Embodiment
Specify below in conjunction with the structure of accompanying drawing to the two float-ball type level measurement devices of the utility model.
Referring to Fig. 1, the structure of the two float-ball type level measurement devices of the utility model comprises pond 1,1 establishes the upper end with the support 8 of support bar 10 in the pond, establish travel switch 7 in support 8 lower ends, establish adjusting nut 9 at support bar 10,12 on the wall that turns at adjusting nut 9 and travel switch 7 is connected with a spring 11, the wall 12 that turns at travel switch 7 is connected with upper floating ball 6 and the lower ball float 3 that is connected by connecting line 4 with the intersection of spring 11, can immerse in the water in order to ensure lower ball float 3, lower ball float 3 is plastic floating ball, its density should be greater than the density of water, and the spacing output loop of travel switch 7 height is connected with the automatic electrical control system (not shown).
The two float-ball type level measurement devices of the utility model in use, first support 8 and support bar 10 are fixed on correct position on the pond 1, again adjusting nut 9 and travel switch 7 and spring 11 are installed, with upper floating ball 6, after connecting, lower plastic floating ball 3 usefulness connecting lines 4 are fixed on the intersection of the connecting lever 12 of spring 11 and travel switch 7, because the density of lower plastic floating ball 3 is slightly larger than water, the direct submerged of meeting, the length of adjusting connecting line 4 remains under the plumbness, lower plastic floating ball 3 is in low spacing 2 places of water level, upper floating ball 6 is in high spacing 5 places of water level, will control with the high-low water level output signal of travel switch 7 Guan Hekai of pond moisturizing electrically operated valve simultaneously.After the utility model was installed, when water level met or exceeded upper floating ball 6, the buoyancy of ball float increased gradually, spring 11 is pulled to upper limit with the connecting lever 12 of travel switch 7, travel switch 7 output high water stage restriction signals, automatic electrical control system is closed the moisturizing motorized valve, and water level progressively descends.After upper floating ball 6 progressively breaks away from the water surface, under the acting in conjunction of two ball float gravity and spring 11 pulling force, connecting lever 12 progressively moves down, when plastic floating ball 3 progressively breaks away from the water surface instantly, under two ball float action of gravitations, spring 11 is stretched, and connecting lever 12 arrives low spacing, travel switch 7 output low-water level signals, automatic electrical control system is opened pond water compensating valve door, the pond water inlet, water level progressively raises, thereby arrives the purpose of automatically measuring and control water level.
Level measurement device of the present utility model can be used for the measurement of the positions such as pond, case, groove.
The utility model is on probation through manufacturing experimently, and proves can carry out reliably level measuring and for automatic control system provides control limit, this device has advantage simple in structure, easy to maintenance, that investment is little, reliability is high simultaneously.
Claims (2)
1. two float-ball type level measurement device, comprise a pond, it is characterized in that establishing the upper end with the support of support bar in the pond, establish travel switch in the support lower end, establish adjusting nut at support bar, be connected with a spring between wall turning of adjusting nut and travel switch, be connected with upper floating ball and the lower ball float that is connected by connecting line at the wall that turns of travel switch with the intersection of spring, the spacing output loop of travel switch height is connected with automatic electrical control system.
