Technical Field

[0001] The invention relates to the technical field of liquid inlet valves, and in particular to a structure of a high-speed liquid inlet valve port for reducing the impact of jet impact. Background Art

[0002] In a large flow rate liquid pump, the flow rate of the liquid inlet is large, the flow rate is fast, and the frequency is high. In order to meet the large flow rate and high flow rate, the liquid inlets need to be opposite. When the two liquid inlets are opposite, the high-speed flowing liquids collide with each other, generating noise and vibration. This causes damage to the relevant parts inside the machine. At the same time, turbulence will also occur. This will cause energy loss and reduce work efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide a structure of a high-speed liquid inlet valve port that reduces the impact of jet impact. The two high-speed jets will not collide by staggered first liquid inlet channels and second liquid inlet channels. Furthermore, noise and vibration are reduced by a buffer structure arranged in the liquid inlet channel, thereby overcoming the defects existing in the prior art.

[0006] It should be noted that a first buffer structure and a second buffer structure are respectively provided along the inner side wall of the first liquid inlet channel, wherein the first buffer structure and the second buffer structure are respectively provided close to the transverse center line of the valve body.

[0007] It should be noted that the first buffer structure is a plurality of first groove teeth, and the plurality of first groove teeth are arranged in sequence along the inner side wall of the first liquid inlet channel.

[0008] It should be noted that a plurality of the first groove teeth are arranged longitudinally.

[0009] It should be noted that the second buffer structure is a plurality of second groove teeth, and the plurality of second groove teeth are arranged in sequence along the inner side wall of the second liquid inlet channel.

[0011] It should be noted that a vortex area is formed between the liquid outlet of the first liquid inlet channel and the liquid outlet of the second liquid inlet channel.

[0012] It should be noted that the axis of the first liquid inlet channel and the axis of the second liquid inlet channel are parallel to each other.

[0013] It should be noted that the axis of the first liquid inlet channel and the axis of the second liquid inlet channel are located in the same plane.

[0014] It should be noted that the axis of the first liquid inlet channel and the axis of the second liquid inlet channel are located in different planes.

[0015] The beneficial effects of the present invention are as follows: the structure of the present invention itself adopts a polymer material with a certain elasticity, which can significantly reduce the impact force on the internal structure and reduce vibration noise, thereby protecting the internal structure from damage; further, the two relatively arranged liquid inlets are staggered with each other to generate a vortex zone in the valve body, thereby suppressing the generation of turbulence; further, by providing a groove tooth structure in the liquid inlet channel, it is possible to reduce noise and vibration, reduce the generation of internal energy, and improve work efficiency.
