Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm pumps, in particular to a valve core drainage and noise reduction structure. Background Art

[0002] A diaphragm pump, also known as a control pump, uses power operation to change the flow rate of the regulated medium and maintain the regulated parameters within the required range, thereby achieving automation of the production process. The fluid of the diaphragm pump enters the pump chamber from the one-way input valve of the valve core, and then the fluid in the pump chamber is discharged from the pump chamber through the one-way discharge valve of the valve core to circulate the fluid. However, when the one-way discharge valve of the existing diaphragm pump discharges the fluid from the pump chamber, the contact area between the discharge valve and the valve core is large and generates a lot of noise. In addition, when the fluid in the pump chamber is discharged from the valve core, the area blocked by the inner side of the valve core is large, generating more reverse sputtering and noise. Therefore, it is necessary to design a new valve core structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0018] The working principle of the valve core drainage noise reduction structure described in the utility model is achieved through the cooperation between the valve core body 1 and the diaphragm 2. Figures 1 to 4 As shown, a support rib 5 is provided on the inner side of the discharge valve 4. The discharge valve 4 contacts the surface of the valve core body 1 through the support rib 5, which can reduce the contact area between the discharge valve 4 and the valve core body 1 during drainage and reduce the noise generated. A guide groove 8 is provided on the inner side of the valve core body 1 in the accommodating cavity, and the area of ​​the fluid in the accommodating cavity that is blocked by the inner side of the valve core body 1 when the fluid is discharged is reduced, thereby reducing the reverse splashing of the fluid and the noise generated. Compared with the traditional diaphragm pump, the valve core drainage noise reduction structure can effectively reduce the noise generated when the valve core is draining.

[0019] Specifically, a receiving groove 11 is provided at the center of the valve core body 1, a limiting block 12 is provided at the center of the bottom surface of the discharge valve 4, and the limiting block 12 of the discharge valve 4 is engaged with the receiving groove 11 of the valve core body 1, wherein the middle part of the valve core body 1 is provided with a rough frosted surface surrounding the receiving groove 11, wherein the support rib 5 is a hollow fan-shaped structure, and a plurality of the support ribs 5 are evenly arranged on the inner side of the discharge valve 4, and a plurality of the support ribs 5 are arranged around the limiting block 12, such as Figures 1 to 4 As shown, the limit block 12 of the discharge valve 4 is inserted into the receiving groove 11 to prevent the discharge valve 4 from rotating on the valve core body 1, and the surface of the valve core body 1 is provided with a rough frosted surface. Compared with the smooth plane, the concave and uneven surface of the valve core body 1 can further reduce the contact area between the two when contacting the discharge valve 4, so as to reduce the noise generated when the discharge valve 4 contacts the valve core body 1, and the rough frosted surface cooperates with the support rib 5 to reduce the contact area between the discharge valve 4 and the surface of the valve core body 1 during drainage, thereby achieving a better noise reduction effect.

[0020] Furthermore, the bottom surface of the receiving groove 11 is provided with a through groove 13, the bottom surface of the limit block 12 is provided with a first slide rod 14, the first slide rod 14 is slidably connected to the through groove 13, and a limiting ring 15 is provided on the first slide rod 14. Furthermore, the top surface of the accommodating cavity is provided with a through hole 16, the top surface of the input valve 7 is provided with a second slide rod 17, the second slide rod 17 is slidably connected to the through hole 16, and a limiting protrusion 18 is provided on the second slide rod 17. Figures 1 to 4 As shown, the fluid enters the accommodating chamber from the input hole 10 of the valve core body 1, and the fluid drives the input valve 7 and the second slide rod 17 to move toward the accommodating chamber and open the input valve 7. The limiting protrusion 18 on the second slide rod 17 can abut against the valve core body 1 to prevent the input valve 7 from falling off the valve core body 1. After the fluid input is completed, the piston 3 in the accommodating chamber drives the fluid in the accommodating chamber to move toward the flow guide groove 8. The piston 3 is configured similarly to the input valve 7, so it is not described in detail. The fluid is discharged from the accommodating chamber from the discharge hole 9, and the fluid drives the discharge valve 4 and the first slide rod 14 to move outward and open the discharge valve 4, thereby performing the fluid delivery work in this cycle.
