Abstract
The invention discloses a safety liquid level control device which comprises a container. Liquid level in the container is divided into a normal liquid level range, an influent liquid level range and an unsafe liquid level range. A first-level liquid level sensing device is arranged on the boundary of the normal liquid level range and the influent liquid level range. A second-level liquid level sensing device is arranged on the boundary of the influent liquid level range and the unsafe liquid level range. The first-level liquid level sensing device and the second-level liquid level sensing device are connected with an external controller. The controller is connected with a display controller. According to the invention, two-level liquid level control is used; the liquid level is divided into the normal liquid level range, the influent liquid level range and the unsafe liquid level range; prompts are given when safety production is affected and cannot be carried out; the liquid level of the container can be well monitored; the production efficiency is improved; double-protection is provided for production; and efficient and safe production is realized.
Description
Technical field
The present invention relates to semi-automation and automatic field, a kind of safety levels control device being realized the production safety management to it when needing to carry out Liquid level by the monitoring of two grades of liquid levels.
Background technology
In some cold liquid machine, the amount of storage of container medium need to be determined, to ensure liquid level within the limits prescribed, so that production process is normally carried out, and ensure that product can be kept the safety in production.So in cold liquid machine, the height of liquid level sensor monitoring liquid level need to be used.
When traditional Liquid level, use one-level Liquid level, generally when liquid level exception being detected, need maintenance down.This mode not only affects production efficiency, also cannot the special circumstances damaged of provisional monitor device.
Summary of the invention
It is an object of the invention to provide a kind of safety levels and control device; use two grades of Liquid level; liquid level is divided into normal level scope, has an impact liquid level scope and three parts of dangerous liquid level scope; and all can make prompting in impact safety in production with when can not keep the safety in production; can be good at the liquid level of monitoring of containers; to improve production efficiency, and provide duplicate protection for producing, thus promote the production of highly effective and safe.
Technical scheme is as follows:
A kind of safety levels controls device, include container, it is characterized in that: the liquid level in described container is divided into normal level scope, has an impact liquid level scope and dangerous liquid level scope, wherein normal level scope and the boundary having an impact liquid level scope are provided with one-level liquid level sensing device, the boundary having an impact liquid level scope and dangerous liquid level scope is provided with two grades of liquid level sensing devices, described I and II liquid level sensing device external controller, described controller connects and has indicating & controlling device.
Described safety levels controls device, it is characterised in that: described I and II liquid level sensing device is respectively adopted mechanical type, electronic type or photoelectric level transducer.
Described safety levels controls device, it is characterised in that: the upper and lower end of described container is respectively equipped with filling opening and tap hole.
The liquid level information that detection is obtained by I and II liquid level sensing device respectively is transferred to controller, and shows in indicating & controlling device.When one-level liquid level sensing device detects liquid level exception, system makes prompting, such as warning etc.；When two grades of liquid level sensing devices detect liquid level exception, system makes instruction, such as shutdown etc..
Filling opening in order to supplement coolant when system loss or micro-leakage, and tap hole can release a small amount of coolant, when keeping in repair container when system filling excess, it is possible to utilizes the liquid in tap hole emptying receptacles.
Beneficial effects of the present invention:
1, the present invention passes through rational deployment, uses two grades of Liquid level, and after control system makes prompting, related personnel has the longer time be adjusted and repair, and can improve production efficiency, has higher practical value.
2, the present invention uses two Sensor monitorings, is equivalent to provide duplicate protection for equipment, makes equipment work more reliable and more stable.
3, the present invention controls simply, convenient, it is easy to accomplish module designs.
4, the present invention is applied widely, can be widely applied to need in the semi-automation of Liquid level and automated system.
Accompanying drawing explanation
Fig. 1 is present configuration theory diagram.
Fig. 2 is the mounting structure schematic diagram of I and II liquid level sensing device in the present invention.
Detailed description of the invention
See Fig. 1,2, a kind of safety levels controls device, include container 1, in container, the liquid level of 1 is divided into normal level scope 8, has an impact liquid level scope 9 and dangerous liquid level scope 10, wherein normal level scope 8 and the boundary having an impact liquid level scope 9 are provided with one-level liquid level sensing device 4, the boundary having an impact liquid level scope 9 and dangerous liquid level scope 10 is provided with two grades of liquid level sensing devices 5, I and II liquid level sensing device 4,5 external controller 2, controller 2 connects and has indicating & controlling device 3.
In the present invention, I and II liquid level sensing device 4,5 is respectively adopted mechanical type, electronic type or photoelectric level transducer.
The upper and lower end of container 1 is respectively equipped with filling opening 6 and tap hole 7.
Below in conjunction with accompanying drawing, the present invention is further illustrated:
If liquid level does not send any signal at normal level scope 8, one-level liquid level sensing device 4, equipment normally works, and indicating & controlling device 3 shows normally；
If liquid level is having an impact liquid level scope 9, one-level liquid level sensing device 4 is signaled to controller 2, if any audible alarm, generate failure code etc., make prompting, and show on indicating & controlling device 3, staff is according to prompting liquid feeding, until liquid level returns to normal level scope 8.Having an impact liquid level scope 9, equipment normally works；
If liquid level is signaled to controller 2, if any audible alarm at dangerous liquid level scope 10, two grades of liquid level sensing devices 5, generate failure code etc., make instruction, and show on indicating & controlling device 3, staff makes corresponding maintenance measures according to instruction, until liquid level returns to normal level scope 8.At dangerous liquid level scope 10, equipment downtime.
Embodiment described above is only to be described the preferred embodiment of the present invention; not the scope of the present invention is defined; on the premise of designing spirit without departing from the present invention; various deformation that technical scheme is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that claims of the present invention determines.
