[0006] The air nozzle can inflate the air bag on one hand and fix the air bag on the other hand, so as to avoid being washed away by the water flow. In a conventional case, the air in the air bag is discharged, and after the air bag is deflated, the pipeline can be normally watered. When the flow of the water in the pipeline needs to be controlled or closed, the air bag is inflated through the air nozzle, so that the space available for the water in the pipeline becomes smaller or even completely disappears.

[0007] Preferably, a plurality of air bags are provided corresponding to one gas source, so as to control multiple pipeline valves simultaneously.

[0008] Preferably, the gas source is an air pump, which facilitates the inflation of the air bag.

[0009] Preferably, the air nozzle of the air bag is sealingly arranged with the side wall of the pipeline body, so as to avoid water leakage at the air nozzle.

[0010] Preferably, the air bag adheres to the inner wall of the pipeline without inflation, so as to reduce the resistance to the water flow in the pipeline when the air bag is not inflated.

[0011] Preferably, the air bag is in the shape of a long strip after inflation, which can increase the contact area with the pipeline body and improve the friction.

[0012] Preferably, the inner wall of the pipeline body is provided with protrusions corresponding to the two ends of the air bag, so as to clamp the air bag between the protrusions of the pipeline body.

[0013] Preferably, the air nozzle is provided with an electric valve. It is convenient to control the inflation and deflation.

[0014] The utility model discloses the beneficial effect:

[0015] This scheme is through the inflation of the air bag in the pipeline, realizes the throttling of the pipeline water flow, and the air bag can automatically adhere to the inner wall of the pipeline, has very good sealing performance, is convenient to control, and can realize automatic control in combination with the air pump.

[0019] In order to deepen the understanding of the utility model, the utility model will be further described in detail below in combination with the drawings and embodiments, and the embodiments are only used to explain the utility model and do not constitute the limitation to the protection scope of the utility model.

[0020] EMBODIMENT

[0021] As Figure 1 Shown, a kind of pipeline throttling valve with air bag, including pipeline body 2, air bag 3 and air source 1;

[0022] The pipeline body 2 is provided with the air bag 3, and the air nozzle 4 of the air bag 3 extends to the outside from the side wall of the pipeline body 2.

[0023] Air nozzle 4 can inflate air bag 3 on one hand, and can fix air bag 3 on the other hand, to avoid being washed away by water flow. In the conventional case, the air in the air bag 3 is discharged, and after the air bag 3 is deflated, the pipeline can be normally water, when the flow of the pipeline water needs to be controlled or closed, air nozzle 4 is inflated to air bag 3, so that the space available for water in the pipeline is smaller or even completely without.

[0024] A plurality of air bags 3 are provided corresponding to one air source 1. So as to control multiple pipeline valves simultaneously. In combination with the control of the air source 1 by the multi-way valve, one of the plurality of air bags 3 can be inflated and deflated.
