Abstract
The utility model discloses a liquid replenishment system. The liquid replenishment system comprises a container and a liquid replenishment tank, wherein the container is connected with the liquid replenishment tank through a delivering pipeline, the delivering pipeline is provided with a liquid metering device, and the delivering pipeline arranged between the liquid replenishment tank and the liquid metering device is also provided with a counterbalance valve. According to the liquid replenishment system, because the delivering pipeline is also provided with the counterbalance valve, when the pressure of a system is less than the setting pressure of the counterbalance valve, an inner diaphragm of the counterbalance valve can block the delivering pipeline under the elastic force action of a spring; when the pressure of the system is more than the setting pressure of the counterbalance valve, the diaphragm compresses the spring, the delivering pipeline is switched on, a self-flowing or siphon phenomenon generated by an annexing agent in the delivering pipeline under the effect of gravity is effectively prevented, and the accuracy of an additive amount of the annexing agent is improved; and the stability of the whole process system is enhanced, and the quality of a product is guaranteed.
Description
Technical field
The utility model relates to the control technique field,, particularly a kind of liquid replenishment system.
Background technique
In the manufacturing of two light Copper Foils, need quantitatively to add additive in producing liquid, the precision of additive adding quantity is huge to the quality influence of two light Copper Foils.Enterprise generally uses metering pump quantitatively to add additive, but when metering pump quits work, additive in conveyance conduit still can flow automatically under Action of Gravity Field or produce siphon, causes the adding quantity inaccuracy of additive, has a strong impact on thereby bring to the quality of production of two light Copper Foils.
The model utility content
Technical problem to be solved in the utility model is: a kind of liquid replenishment system is provided, prevent that the additive in conveyance conduit from flowing automatically or producing siphon under Action of Gravity Field, improve the precision of additive adding quantity, strengthened the stability of whole process system, guaranteed the quality of product.
For solving the problems of the technologies described above, the utility model proposes a kind of liquid replenishment system, comprise container and fluid infusion groove, this container is connected with the fluid infusion groove by conveyance conduit, conveyance conduit is provided with liquid metering device, also is provided with back pressure valve on the conveyance conduit between described fluid infusion groove and liquid metering device.
Further, described conveyance conduit is provided with flow control valve.
Further, the conveyance conduit between described liquid metering device and back pressure valve is provided with switch, and the conveyance conduit between described liquid metering device and switch is provided with outlet valve.
Further, described liquid metering device is metering pump.
Technique scheme has following beneficial effect at least: the utility model also is provided with back pressure valve by adopting on conveyance conduit, when system pressure than back pressure valve setting pressure hour, the inner diaphragm of back pressure valve stops up conveyance conduit under the elastic force effect of spring, when system pressure is larger than back pressure valve setting pressure, the diaphragm Compress Spring, conveyance conduit is connected, prevented that effectively the additive in conveyance conduit from flowing automatically or producing siphon under Action of Gravity Field, improved the precision of additive adding quantity, strengthen the stability of whole process system, guaranteed the quality of product.
Description of drawings
Fig. 1 is the structural representation of the utility model liquid replenishment system.
Embodiment
Need to prove, in the situation that do not conflict, embodiment and the feature in embodiment in the application can make up mutually.Below in conjunction with accompanying drawing, the utility model is described further.
As shown in 1 figure, the utility model embodiment's liquid replenishment system comprises container 1, fluid infusion groove 2, conveyance conduit 3 and is successively set on flow control valve 6, liquid metering device 4, outlet valve 8, switch 7, back pressure valve 5 on conveyance conduit 3, flow control valve 6 is communicated with container 1 entrance by conveyance conduit 3, back pressure valve 5 is communicated with fluid infusion groove 2 by conveyance conduit 3, and liquid metering device 4 is metering pump.
During work, than back pressure valve 5 setting pressures hour, the inner diaphragm of back pressure valve 5 stops up conveyance conduit 3 under the elastic force effect of spring when system pressure, when system pressure than back pressure valve 5 setting pressures when large, the diaphragm Compress Spring, conveyance conduit 3 is connected.Prevented that effectively the additive in conveyance conduit 3 from flowing automatically or producing siphon under Action of Gravity Field, improved the precision of additive adding quantity, strengthened the stability of whole process system, guaranteed the quality of product; Flow control valve 6 is installed on the conveyance conduit 3 of 4 of container 1 entrance and liquid metering devices, adjusts conveyance conduit 3 internal channels sizes by flow control valve 6, is used in combination with liquid metering device 4, improves the accuracy of metering numerical value; Switch 7 is installed on the delivery pipe of 5 of liquid metering device 4 and back pressure valves, and outlet valve 8 is installed on the conveyance conduit 3 of 4 of switch 7 and liquid metering devices, and before use, first closing switch 7 utilizes outlet valve 8 that the air exhausting of liquid metering device 4 inside is removed.
The utility model also is provided with back pressure valve by adopting on conveyance conduit, when system pressure than back pressure valve setting pressure hour, the inner diaphragm of back pressure valve stops up conveyance conduit under the elastic force effect of spring, when system pressure is larger than back pressure valve setting pressure, the diaphragm Compress Spring, conveyance conduit is connected, prevented that effectively the additive in conveyance conduit from flowing automatically or producing siphon under Action of Gravity Field, improved the precision of additive adding quantity, strengthen the stability of whole process system, guaranteed the quality of product.
The above is embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
