Abstract
The utility model discloses a pipe flow rate regulating structure which comprises a liquid conveying pipe, wherein a water pump is arranged in the middle of the liquid conveying pipe. The pipe flow rate regulating structure is characterized in that a return pipe with a valve is connected between a water inlet and a water outlet of the water pump. According to the pipe flow rate regulating structure, the return pipe with the valve is adopted to solve the problem of flow rate regulation, the cost is low, no complicated circuit is needed, the requirements on maintenance personnel are low, and the flow rate regulation is easily achieved.
Description
Technical field
The utility model relates to the structure that a kind of pipeline flow is regulated.
Background technique
When using line transportation liquid, need carry out the control of flow usually.Existing technology generally is a water pump to be set at the middle part of pipeline carry out flow control, but this kind method requires to adopt the frequency-variable electronic device that the rotating speed of motor is adjusted usually than higher to the speed adjustment device of pump motor; Reach flow is adjusted, this regulative mode has a lot of advantages; But because the present sale price of electronics frequency modulator is very high; After the frequency conversion adjustment, pipeline flow regular hour of can fluctuating just can reach stable, and attendant's technical requirements is also very high; Repair cost is also and then higher, so user cost is just than higher.
The model utility content
It is low, simple in structure that the purpose of the utility model provides a kind of cost, can reach stable pipeline flow regulation structure rapidly after the flow adjustment.
To achieve these goals, adopt following technological scheme: a kind of pipeline flow regulation structure comprises that the middle part has the liquid conducting pipes of water pump, is characterized in that: be connected with the reflux line with valve between said pump intake and the water outlet.
The utility model has only adopted a reflux line that has valve just to solve the problem of flow adjustment, and cost is little, need not complicated circuit, and is lower to attendant's requirement, is easy to realize.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explanation.
As shown in Figure 1, a kind of pipeline flow regulation structure comprises that the middle part has the liquid conducting pipes 1 of water pump 2, is connected with the reflux line 4 with valve 3 on the water intake of said water pump 2 both sides and the pipeline of water outlet.
When carrying out the flow adjustment, only need regulating valve 3, regulate the flow in the reflux line, thereby easily the feed flow in the conveyance conduit is compared accurate adjustment.
The utility model is simple in structure, is easy to realize, and is with low cost.
More than show and described the advantage of basic principle, major technique characteristic and the utility model of the utility model.The utility model is not restricted to the described embodiments, the principle of describing in the foregoing description and the specification that the utility model just is described., all belong in the scope of the utility model technological scheme any simple modification, equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
