Description
Technical field
The utility model is related to a kind of compound liquid level control switch, and particularly a kind of display type float-type on the spot can adjust
Pond liquid level controlling switch.
Background technology
Closed steam turbine drainage collection pond is equipped with outside the steam turbine building of industrial premises come in collecting the steam turbine course of work
The waste water of generation, usually contains temperature water and steam higher in the collecting pit.To ensure that the water level in collecting pit maintains one
In fixed safe range, steam turbine drainage collection is typically provided with a set of automatic control system in pond, i.e., by liquid-level switch come automatic
Control two draining pumps start or stop to make water level be maintained at zone of reasonableness.At present, factory mostly uses and is set in collecting pit
Floating-ball level switch is put to control two startups and stopping of draining pump, but because water and vapor (steam) temperature are too high, Floating Ball Liquid Level is opened
Pass is often ruined, and floating-ball level switch Liquid level is inaccurate, the situation that the idle running of draining pump motor burns out often occurs,
And because collecting pit opening is smaller, operations staff's observation liquid level is inconvenient.Therefore, the Liquid level in steam turbine drainage collection pond is urgently
Treat that a kind of Liquid level is accurate, ensure the safe and stable operation of equipment, while the Liquid level for being easy to operations staff to patrol and examine again is opened
Close.
The content of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned existing steam turbine drainage collection pond control liquid level to use
Floating-ball level switch deficiency, and provide that a kind of Liquid level in steam turbine drainage collection pond is accurate, ensure the safety and stability of equipment
Operation, while be easy to the liquid level control switch that operations staff patrols and examines again, i.e. display type float-type adjustable water pit level control on the spot
System switch.
The technical scheme in the invention for solving the technical problem is：A kind of display type float-type on the spot can adjust
Pond liquid level controlling switch, it includes the top tub master for being provided with turning plate indicator and scale linked into an integrated entity by adpting flange
Body and the interior bottom protection jacket casing for setting ball float, the turning plate indicator are made up of magnetic color chips, and it is arranged on outside tub main body
Side, it is provided with scale above, and one group of adjusting action switch is separately installed with the top H scales and bottom L scales of scale；
The ball float is provided with the floating ball rod being made up of magnetic core material, and floating ball rod is by extending to top bucket in the protection jacket casing of bottom
In groove body, floating ball rod top carries magnet, the adjustable pond of this float-type of display type on the spot that the utility model is provided
Liquid level control switch when in use, realization fixed installation, its underpart is connected with the vessel flange of collecting pit by by adpting flange
The protection jacket casing for inside setting ball float is placed in hand collecting pit, and ball float is floated on the surface by buoyancy, when liquid level rises in pond,
Moved up by the ball float of buoyancy effect, so that floating ball rod is moved up, when floating ball rod rises, by floating ball rod top
Liquid level shown and color change in the influence that end magnet rises, corresponding magnetic color chips there is；When liquid level makes magnet be less than L liquid
Step switch is failure to actuate during position, from without interlocked startup draining pump motor, with the rising of liquid level, when liquid level makes magnet high
When H liquid levels, the step switch at H liquid levels is touched, so that draining pump interlocked startup is triggered, as draining pump startup is received
Liquid level declines in collection pond, the step switch when liquid level makes magnet be less than L liquid levels at triggering L liquid levels, stops draining pump
Draining.
The electric shock capacity of above-mentioned adjusting action switch can be according to the electric control loop of automatic control system in collecting pit
It is required that setting.
The utility model provide this float-type of display type on the spot adjustable water pit level controlling switch, its ball float and
The protection sleeve fixed by flange is provided with outside floating ball rod, prevents water impact from causing ball float that big fluctuation occurs, so that anti-
Only level gauging is forbidden；Adjustable step switch is placed in outside pond, is not in scorch phenomenon, and the step switch liquid level
Precise control, has prevented the situation appearance that the idle running of draining pump motor burns out, it is ensured that equipment safety stable operation；Its top is turned over
Plate indicator and scale are arranged at outside collecting pit, are easy to operations staff to patrol and examine；It applies also for any high-temperature pool or phase
Measurement to special media in closed pond, and two position control and alarm in pond；Its simple structure, easy construction, design
Rationally, actually used value is high.

Specific embodiment
With reference to embodiment, the utility model is described in further detail, but is not intended to limit protection model of the present utility model
Enclose.
The utility model embodiment provides a kind of display type float-type adjustable water pit level controlling switch on the spot, and it includes
The top tub main body 3 for being provided with turning plate indicator 1 and scale 2 that is linked into an integrated entity by adpting flange 6 and interior set under ball float 8
Portion protects jacket casing 9, the turning plate indicator 1 to be made up of magnetic color chips, and it is arranged on the outside of tub main body 3, and it is provided with mark above
Chi 2, is separately installed with one group of adjusting action switch at the top H scales and bottom L scales of scale 2；Set on the ball float
There is a floating ball rod 5 being made up of magnetic core material, floating ball rod 5 is by extending to top tub main body 3 in the protection jacket casing 9 of bottom
Interior, the top of floating ball rod 5 carries magnet 4.
This float-type of the display type on the spot adjustable water pit level controlling switch that the utility model is provided when in use, is led to
Cross and adpting flange 6 is connected realization fixed installation with the vessel flange 7 of collecting pit, the protection jacket casing 9 that ball float 8 is set in its underpart is put
