Abstract
The utility model relates to a feed pipeline flow control system which comprises a storage device and a feed pipeline, wherein the feed pipeline is communicated with the storage device. The system also comprises a backflow pipe, wherein one end of the backflow pipe is connected with the storage device, the other end of the backflow pipe is connected with the feed pipeline, a flow control valve is arranged on the backflow pipe, a power pump is arranged on the feed pipeline, and the power pump is positioned between the joints of the storage device with the backflow pipe and the feed pipeline. The feed pipeline flow control system provided by the utility model has the advantages that as the backflow pipe is arranged on the feed pipeline and the flow control valve is arranged on the backflow pipe, when in use, the flow control valve is directly regulated so that materials are uniformly obtained at the working end without necessity of intermittently opening and closing the power pump, thereby reducing the damage degree of the power pump and facilitating control on the feed speed of the feed pipeline.
Description
Technical field
The utility model relates to prepares chemical raw material field, relates in particular to a kind of feed pipe flow control system.
Background technology
In prior art, when preparing chemical raw material, feed pipe directly adopts kinetic pump to carry out transferring raw material, but in course of conveying, its flow is uncontrollable, when the amount that needs when preparation district is enough, direct closing device, while lacking, open the kinetic pump of equipment, then carry, so, time-consuming, and kinetic pump is also had to damage to a certain degree, be unfavorable for the long-run development of producing.
Utility model content
In view of this, be necessary to provide a kind of control, and reduce the feed pipe flow control system to kinetic pump infringement.
The utility model is achieved in that feed pipe flow control system, comprises storage device and feed pipe, described feed pipe is communicated with storage device, also comprises return duct, and one end of described return duct connects storage device, the other end connects feed pipe, and described return duct is provided with flow control valve.
Further, described feed pipe is provided with kinetic pump, and described kinetic pump is between storage device and return duct and the junction of feed pipe.
The advantage of the feed pipe flow control system that the utility model provides is: by return duct is set on feed pipe, and flow control valve is set on return duct, in use, directly regulate flow control valve, make working end obtain uniformly material, while opening while not needing, close kinetic pump, reduce the damaged condition to kinetic pump, and be convenient to control the charging rate of feed pipe.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model feed pipe flow control system.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is the structural representation of the utility model feed pipe flow control system.
Described feed pipe flow control system, comprises storage device 10 and feed pipe 20, and described feed pipe 20 is communicated with storage device 10, also comprise return duct 30, one end of described return duct 30 connects storage device 10, and the other end connects feed pipe 20, and described return duct 30 is provided with flow control valve 31.
Described feed pipe 20 is provided with kinetic pump 40, and described kinetic pump 40 is between storage device 10 and return duct 30 and the junction of feed pipe 20, for feed pipe 20 provides the power of convey materials.
By return duct 30 is set on feed pipe 20, and flow control valve 31 is set on return duct 30, in use, directly regulate flow control valve 31, make working end obtain uniformly material, while opening while not needing, close kinetic pump 40, reduce the damaged condition to kinetic pump 40, and be convenient to control the charging rate of feed pipe 20.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
