Description
Technical field
The utility model relates to a kind of liquid level warning with power condition switch and cut-off system, belongs to Liquid level field.
Background technology
Pot type fortune filling car needs to limit carrying capacity when installing oil plant additional, otherwise oil plant can overflow from the emergency relief valve of roof manhole lid.Tank vehicle generally adopted high Liquid level valve system to limit carrying capacity in the past, and this system comprises the self-closing valve be located at bottom flow container and the float ball controller being located at flow container inside.In the last few years along with the security requirement of country to pot type fortune oiling vehicle is more and more higher, the oil inlet of pot type fortune filling car is forced to require to install additional the charge of oil valve with emergency cut-off function, self-closing valve originally does not possess emergency cut-off function, therefore directly can not be contained in tank base.If adopt the mode of quick action emergency valve series connection self-closing valve, can increase cost, simultaneously because the valve body of self-closing valve own is comparatively large, and near oil inlet at the bottom of tank, space is very narrow, then a quick action emergency valve of connecting can make pipeline be difficult to arrangement.
Utility model content
Technical problem to be solved in the utility model is, overcome the shortcoming of prior art, manage directly to control gas control bottom valve to realize the limitation function to flow container carrying capacity, thus achieve and reduce costs and simplify pipeline near charge of oil mouth and meet the object that national relevant industries specify simultaneously.The utility model provides liquid level warning and the cut-off system of the band power condition switch that a kind of structure is simple, cost is low, Measure Precision is high.
In order to solve above technical matters, the utility model provides a kind of liquid level warning with power condition switch and cut-off system, comprises flow container and is arranged on the liquid level detector on flow container and is arranged on the guard box of flow container dress liquid mouth; It is characterized in that: also comprise annunciator and power condition switch; Described annunciator is connected on the outlet line of liquid level detector; The power input line road that described power condition switch is connected on liquid level detector is fixedly mounted in guard box, a jacking block is installed inside the chamber door of described guard box, described jacking block installation site is corresponding with the position of power condition switch, chamber door has opening and closing two kinds of positions, and when chamber door is opened, power condition switch connects liquid level detector power supply; When chamber door is closed, jacking block withstands power condition switch, and power condition switch closes liquid level detector power supply.
The technical scheme that the utility model limits further is:
Further, also comprise the gas control bottom valve be arranged on bottom flow container, described gas control bottom valve is arranged between flow container and dress liquid mouth.
Further, also comprise electromagnetism Pneumatic valve, described electromagnetism Pneumatic valve connect liquid level detector outlet line, under connect gas control bottom valve control mouth.
The beneficial effects of the utility model are: the utility model realizes the limitation function to flow container carrying capacity by the gas control bottom valve directly controlling to have emergency cut-off function, national relevant industries regulation can be met, again because of gas control bottom valve compact conformation, very effectively can simplify the arrangement of tank base pipeline, and this system eliminates expensive self-closing valve, greatly reduce cost, this system also add warning function simultaneously.In addition country have relevant laws and regulations to specify the dress liquid mouth of carriage of dangerous goods car must be integrated in guard box; and the power condition switch in the utility model is by being automatically switched on or switched off the power supply of whole system with the opening and closing of guard box chamber door, thus take full advantage of environmental conditions to the step that simplifies the operation.Native system also has the following advantages: native system is without any the switch needing human users, and in system, the function of power condition switch relies on the related realization of operation of opening chamber door in operation; Native system simplifies the distribution of flow container bottom conduit, and reliability is high, easy for installation, and maintenance accessi bility is good; Cutoff function being realized by controlling gas control bottom valve, cancelling expensive self-closing valve, saving cost.

Detailed description of the invention
embodiment 1
A kind of liquid level warning with power condition switch that the present embodiment provides and cut-off system, as shown in Figure 1: comprise flow container 1 and be arranged on the liquid level detector 2 on flow container 1 and be arranged on the guard box 3 of flow container dress liquid mouth; The gas control bottom valve 10 also comprising annunciator 4, power condition switch 5, electromagnetism Pneumatic valve 9 and be arranged on bottom flow container.
Electromagnetism Pneumatic valve 9 connects the outlet line of liquid level detector 2, under connect the control mouth of gas control bottom valve 10.Annunciator 4 is connected on the outlet line of liquid level detector 2; Power condition switch 5 is connected on the power input line road of liquid level detector 2, and be fixedly mounted in guard box 3, a jacking block 7 is installed inside the chamber door 6 of guard box 3, jacking block 7 installation site is corresponding with the position of power condition switch 5, chamber door 6 has opening and closing two kinds of positions, when chamber door 6 is opened, power condition switch 5 is in electriferous state, connects liquid level detector power supply; When chamber door 6 is closed, jacking block 7 withstands power condition switch 5, and power condition switch 5 is in off-position, closes liquid level detector power supply.
Power condition switch 5 is connected according to the current dress liquid status that whether is in or closes the power supply of liquid level detector 2, thus under controlling different operating mode, whether whole system works.The level sensor 8 of liquid level detector 2 is installed on flow container 1 inner setting height, when the liquid level 11 in flow container 1 arrives this height, described liquid level detector 2 sends signal to described annunciator 4 and described electromagnetism Pneumatic valve 9, described annunciator 4 gives the alarm notice operating personal, and described electromagnetism Pneumatic valve 9 converts electrical signals to gas control bottom valve 10 described in gas signal control and ends sacking.
Whether power condition switch 5 controls " warning cut-off system " and works under different operating mode.When chamber door 6 is closed, jacking block 7 withstands power condition switch 5.Whether power condition switch 5 controls the triggering of whole system by controlling the power supply of liquid level detector.When carrying out the operation of dress liquid to flow container, power condition switch energy instant on " liquid level warning of band power condition switch and cut-off system ", when after the end of job of dress liquid, power condition switch closes whole system automatically.Liquid level detector detects and to send on-off signal when liquid level in flow container reaches certain setting value and start annunciator and close gas control bottom valve by electromagnetism Pneumatic valve, the operation of cut-off dress liquid.The effect of power condition switch is established to be that, if when liquid level is not taken measures when reaching alarm value, whole system will give the alarm always herein.Especially be in motion when flow container, such as truck tanker travels jolting on road surface or acclive road, and in it, liquid level can fluctuate up and down, if do not have power condition switch, whole system can sporadically be waken up.
In addition to the implementation, this patent also can have other embodiment, such as cancels annunciator, installs power condition switch by other means, as first-class in power condition switch being fixed on charge of oil valve.The technical scheme that all employing equivalents or equivalent transformation are formed, within the protection domain all dropping on this patent requirement.
