Description of drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the accompanying drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description These are only some embodiments of the utility model, and those skilled in the art can also obtain other drawings based on these drawings without creative work.

Fig. 1 is the structural representation of the utility model.

detailed description

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

Referring to FIG. 1 , the high-suction pneumatic diaphragm pump provided by the present invention includes a diaphragm pump body 100 .

Diaphragm pump body 100, which is an existing diaphragm pump, is provided with a feed pipe 200 and a discharge pipe 300 communicating with the inside of the diaphragm pump body 100. When the diaphragm pump body 100 works, it will generate suction. The diaphragm pump body 100 The liquid is sucked in through the feed pipe 200 and discharged through the discharge pipe 300 .

In order to increase the suction lift of the diaphragm pump, the present application sets the diaphragm pump into a U-shaped structure, specifically, an infusion tube 400 is provided on the diaphragm pump body 100 .

The infusion tube 400 is specifically L-shaped, and after the infusion tube 400 is connected to the diaphragm pump body 100, the diaphragm pump as a whole is U-shaped.

When the liquid enters the feeding pipe 200, it can enter the infusion pipe 400 from top to bottom. When it flows in, it will give the diaphragm pump body 100 a certain air pressure. When the diaphragm pump body 100 works, the infusion pipe 400 and the diaphragm pump body The liquid in 100 will flow, and the pulling force of the liquid will cause the diaphragm pump body 100 to be sucked in, and then discharged through the discharge pipe 300, which can greatly increase the suction lift of the diaphragm pump.

The infusion tube 400 is specifically composed of a first pipeline 410 , a second pipeline 420 and a third pipeline 430 connected in sequence.

The first pipe 410 is horizontal and perpendicular to the feed pipe 200 , and the liquid flows into the first pipe 410 first.

The third pipe 430 is also horizontal and communicates with the feeding pipe 200 horizontally.

The second pipe 420, which is arranged between the first pipe 410 and the third pipe 430, is in the shape of an arc with an arc of 90 degrees, and it is used to quickly flow the liquid flowing in from the first pipe 410 into the second pipe 410. Three pipes 430, so as to flow into the feed pipe 200.

In order to control the flow rate of the liquid in the infusion tube 400 , a ball valve 500 is provided on the first pipe 410 , and the liquid can be injected into the first pipe 410 only after the ball valve 500 is opened.

In addition, a three-way valve 600 is also provided on the first pipeline 410. The three-way valve 600 is used to control the injection amount of the liquid in the infusion tube 400. When the liquid in the infusion tube 400 is filled, the three-way valve 600 Excess fluid will be drained.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model The new model also has various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection required by the utility model is defined by the appended claims and their equivalents.
