Abstract
The utility model provides a feed liquid backflow preventing device of a cut rolled stem feeder. The feed liquid backflow preventing device comprises a main pipeline connected with a feeder, wherein the other end of the main pipeline is respectively connected with a vertical first pipeline and a horizontal second pipeline through a three-way ball valve, the first pipeline is connected with a feeding pump outlet through a pneumatic ball valve, the second pipeline is connected with the top of a storage tank, the bottom of the storage tank is connected with a feeding pump inlet through a third pipeline, a flow meter is arranged on the first pipeline between the three-way ball valve and the pneumatic ball valve, the flow meter is electrically connected with a controller, and the control end of a feeding pump is also electrically connected with the controller; and the control end of the pneumatic ball valve is connected with a two-position three-way electromagnetic valve which is electrically connected with the controller. The feed liquid backflow preventing device is simple in structure and practical in function, the problem of feed liquid backflow is effectively solved, fluctuation of feeding at the beginning stage is effectively avoided, feeding stability is enhanced, and control capacity of the production process is improved.
Description
Technical field
The utility model relates to a kind of stem charger feed liquid back-flow preventer.
Background technique
It is pre-filled that stem charger will carry out feed liquid to blank pipe road before reinforced, makes blank pipe fill up feed liquid.After pre-filled completing, because liquid level in pipeline is higher than the liquid level of storage tank, the feed liquid in pipe slowly flows backwards back in storage tank again under differential pressure action, and making to approach in one section of pipeline of charger does not have feed liquid, does not reach the pre-filled object of pipeline.
Model utility content
The utility model provides a kind of stem charger feed liquid back-flow preventer, and technical problem to be solved is:.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of stem charger feed liquid back-flow preventer, comprise the main pipeline being connected with charger, the main pipeline the other end is connected with the first pipeline and the horizontally disposed second pipe of vertical setting respectively by tee ball valve, the first device for cleaning pipeline is crossed pneumatic ball valve and is connected with charge pump outlet, second pipe is connected with storage tank top, and storage tank bottom is connected with charge pump entrance by the 3rd pipeline.
On first pipeline between tee ball valve and pneumatic ball valve, be provided with flowmeter, flowmeter is electrically connected with controller, and charge pump control end is also electrically connected with controller; Pneumatic ball valve control end is connected with two-bit triplet solenoid valve, the electrical connection of two-bit triplet solenoid valve controller.
The utility model is simple in structure, practical function, not only efficiently solves feed liquid reflux problem, and effectively avoids reinforced incipient stage fluctuation, has increased reinforced stability, improves product process control ability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment: as shown in Figure 1, a kind of stem charger feed liquid back-flow preventer, comprise the main pipeline 2 being connected with charger 1, main pipeline 2 the other ends are connected with the first pipeline 4 and the horizontally disposed second pipe 5 of vertical setting respectively by tee ball valve 3, the first pipeline 4 is connected with charge pump 9 outlets by pneumatic ball valve 8, second pipe 5 is connected with storage tank 6 tops, and storage tank 6 bottoms are connected with charge pump 9 entrances by the 3rd pipeline 10.
On first pipeline 4 between tee ball valve 3 and pneumatic ball valve 8, be provided with flowmeter 7, flowmeter 7 is electrically connected with controller, and charge pump 9 control ends are also electrically connected with controller; Pneumatic ball valve 8 control ends are connected with two-bit triplet solenoid valve, the electrical connection of two-bit triplet solenoid valve controller.
Make tee ball valve 3 pre-filled and open when reinforced, pre-filled end and reinforced stopping are closed in time afterwards.
Join the opening, open of two-bit triplet electromagnetic valve pneumatic ball valve 8 of cabinet setting at gas, automatically control solenoid valve by control program according to the working state of charger, when pre-filled, two-bit triplet solenoid valve obtains electricly, and pneumatic ball valve 8 is opened, solenoid valve dead electricity when pre-filled stopping, pneumatic ball valve 8 is closed.
