Description
Technical field
The utility model relates to a kind of floating roof tank high level switches, belong to oiling product oil storage and transportation technical field.
Background technique
Oiling product storage tank requires that high liquid level warning device should be arranged according to existing national regulation, which is higher than in liquid level sets
When counting desired liquid level, alarm signal is transmitted to central control system, central control system realizes alarm, interlock protection function.
Crude oil floating roof tank generally selects Fork LIquid Level Switch, radio frequency admittance level gauge switch and supersonic liquid level to open at present
It closes, but effect is undesirable, wherein Fork LIquid Level Switch is attached in tuning fork mechanism, be will have a direct impact on due to the viscosity of crude oil
The work of Fork LIquid Level Switch；Radio frequency admittance level gauge switch and ultrasonic liquid level switch, the difference of meeting based on crude medium, and
The influence of crude oil attachment causes measurement accuracy very low, and false alarm frequency is high.Above-mentioned three kinds of liquid-level switches not can guarantee alarm, connect
The reliability service for locking defencive function, affects the safety in production of oiling product storage and transportation.
With the generation of oiling product storage and transportation production accident in recent years, country keeps the safety in production to it, and more stringent requirements are proposed,
The high level switch for installing high reliability, realizes alarm, the interlock protection function of central control system, is to guarantee oiling product storage and transportation production
The important measures of safety.
And to being equipped with the floating of the Fork LIquid Level Switch of low reliability, radio frequency admittance level gauge switch and ultrasonic liquid level switch
Top storage tank is transformed, and how in the case where not fire operation, is transformed to original system, is guaranteed in transformation process
Safety, is the important topic put in production manager and modifier.
Utility model content
For solve the prior art measurement accuracy is low, false alarm, mounting process are complicated, the technical problems such as safe and reliable, this
Utility model provides a kind of floating roof tank high level switch, has the characteristics that safe and reliable, measurement accuracy is high.
The technical solution of the utility model is as follows: floating roof tank high level switch, including shell, the outer casing bottom setting
Fixing clamp-seat, the Fixing clamp-seat are fixed by bolts on floating roof upper end tank skin, and setting limit is opened in the shell
It closes, swing rod is set on limit switch, swing rod connects weight by wirerope, pulley, is fixed with extreme position in the shell
Block, the limit switch is interior to be arranged sensing element, and sensing element connects warning device.
Further, the material of the shell is 304 stainless steels.
Further, the limit switch is explosion-proof Limit switch.
Further, the Fixing clamp-seat is fixed on floating roof upper end tank skin by four stainless steel bolts.
Further, the wirerope is stainless steel wirerope diameter 2mm.
Further, the weight material is lead, weight 4kg.
The beneficial effects of the utility model are as follows: the utility model structure is simple, reliable performance, it is easy for installation, can be accurate
Reflect that the height of floating roof jar liquid surface, precision are high.And will not because of crude oil medium difference and to precision generate deviation.Safety is to ring
Border is pollution-free, energy conservation and environmental protection.
Detailed description of the invention
Fig. 1 is the main view of floating roof tank low liquid level switch；
Fig. 2 is the top view of Fig. 1 shown device；
Wherein: 1, shell, 2, Fixing clamp-seat, 3, limit switch, 31, swing rod, 4, wirerope, 5, pulley, 6, counterweight, 7, pole
Extreme position block.
Specific embodiment
The utility model is described further with reference to the accompanying drawing:
As shown in Figs. 1-2, Fixing clamp-seat 2 is arranged in floating roof tank high level switch, including shell 1,1 bottom of shell,
The Fixing clamp-seat 2 is fixed by bolts on floating roof upper end tank skin, and limit switch 3, limit are arranged in the shell 1
Swing rod 31 is set on switch 3, and swing rod 31 connects weight 6 by wirerope 4, pulley 5, is fixed with limit position in the shell 1
Block 7 is set, sensing element is set in the limit switch 3, sensing element connects warning device.The material of the shell 1
For 304 stainless steels.The limit switch 3 is explosion-proof Limit switch.The Fixing clamp-seat 2 is solid by four stainless steel bolts
Due on floating roof upper end tank skin.The wirerope 4 is stainless steel wirerope diameter 2mm.6 material of weight is lead,
Weight is 4kg.
When in use, weight 6 is tensed the structure of the utility model by gravity, wirerope 4, and 31 under tension of swing rod is made
With right positions in Fig. 1 are swung to, to avoid damage limit switch 3, limit of utilization position stop at swing rod 31 to alert locations
7 production positioning devices.The pulling force of weight 6 can be completely counterbalanced by by extreme position block 7, guarantee 3 rotary part of limit switch not
It will receive pulling force effect.When floating roof is raised up to high liquid level height, weight 6 is lifted by oil tank floating roof, and wirerope 4 does not stress.Swing rod
31 lean on the elastic device of itself to restore to original position, and swing rod 31 is restored to upright position in Fig. 1 at this time, and limit switch 3 is alarmed.
By investigating and studying, the floating roof of crude oil floating roof tank can be gone up and down, the position of floating roof with the height of crude oil liquid level
The actual position that can reflect liquid level in tank installs this on tank skin edge corresponding position at the top of the floating roof tank according to this rule
The device of utility model.When liquid level is also less than alert locations, weight 6 will not induction alarm by gravity limit switch 3；?
When liquid level reaches alert locations, weight 6 is moved up with floating roof, and wirerope 4 loses pulling force effect high level switch and issues alarm
Signal.
It is connected by screw bolts when installation, facilitates installation, it can also be to avoid safety accident caused by fire operation.This is practical new
The floating roof tank high level switch of type, using simple theory of mechanics and electrical component, not with crude oil physical contact between media, so that it may
To play the role of high liquid level warning, while having the characteristics that safe and reliable, measurement accuracy is high.
Belong to explosion-proof 1st area of operation in crude oil floating roof tank tank field, limit switch 3 should be using the product for having explosion-proof qualification.
Installation process: the size design fastener at benefit tank skin edge when installation, steel wire: 4 length in reserve refers to floating roof tank
Requirement of the design drawing to high liquid level height.Limit switch 3 should use explosion-proof Limit switch.Shell is using attractive and durable stainless
304 material of steel, it is easy to disassemble.The inter-agency smooth no card resistance phenomenon of cooperation.6 weight of weight will guarantee to have a down dip angle swing in windy conditions
Dynamic range avoids touching tank skin.
Above-described embodiment is only intended to citing and explanation to the utility model, and is not intended to limit the invention to
Within the scope of described embodiment.Furthermore it will be appreciated by persons skilled in the art that the utility model is not limited to above-mentioned reality
Example is applied, introduction according to the present utility model can also make more kinds of variants and modifications, these variants and modifications all fall within this
In utility model range claimed.
