Description
Technical Field
[0001] The utility model belongs to the technical field of diaphragm pumps, and specifically relates to a pressure-relieving water diaphragm pump. Background Art

With its unique structure and working principle, the water diaphragm pump can effectively transport various corrosive, highly viscous, and solid-particle-containing liquids, and has the advantages of no leakage, no pollution, and easy maintenance.
[0003] At the current technical level, the water diaphragm pump usually consists of main components such as an isolation tank, a diaphragm, and inlet and outlet ports. Its working principle is to introduce high-pressure clear water into the isolation tank through a high-pressure water pump to squeeze the diaphragm to deform, change the volume on both sides of the diaphragm, and thus discharge the material inside the diaphragm.
[0004] At the present stage, the water diaphragm pump has achieved certain technical effects in practical applications. For example, it can achieve precise flow control and adapt to the transportation requirements under different working conditions; it can handle various complex-property materials and has strong versatility; due to the isolation effect of the diaphragm, it can effectively prevent material leakage and ensure the safety and environmental protection of the production process.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model.

At this time, the one-way valve 25 in the water outlet channel is opened, and the isolation tank 10 is in a drainage state. During the discharging process, the one-way valve 25 in the water inlet channel is opened to introduce high-pressure clean water. The material in the diaphragm 11 is under pressure and flows through the feeding port 16 of the partition 13 towards the discharging channel 18. The material pushes the retaining ring 22, compressing multiple groups of small dampers 23 and multiple groups of second return springs 24.

[0041] Further, in the above technical solution, the top end of the flange structure of the diaphragm 11 contacts the bottom end of the flange structure of the isolation tank 10, and the bottom end of the flange structure of the diaphragm 11 contacts the top end of the flange structure of the feeding and discharging channel 12.
[0042] Further, in the above technical solution, sealing gaskets are provided on the contact surfaces between adjacent flange structures.
[0043] Specifically, the principle of the present utility model is as follows: When the pressure-relieving water diaphragm pump starts to work, during the feeding process, the control valve 26 is opened, and the high-pressure material passes through the feeding and discharging channel 12 and enters the feeding channel 17 through the material guiding port 16. The pressure of the material pushes the retaining piece 19, compressing the damper 20 and the first return spring 21. The damper 20 and the first return spring 21 absorb and buffer the pressure, reducing the impact force of the material on the diaphragm 11; the material after buffering enters the inside of the diaphragm through the feeding port on the side wall of the feeding channel 17. At this time, the one-way valve 25 in the water outlet channel is opened, and the isolation tank 10 is in a drainage state; during the discharging process, the one-way valve 25 in the water inlet channel is opened, and high-pressure clean water is introduced. The material in the diaphragm 11 is under pressure and flows through the material guiding port 16 of the partition plate 13 towards the discharging channel 18.
