DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the adjustable flow beer faucet includes a valve body 1, a ball core 2 and a wine outlet pipe 3, the valve body 1 has a wine inlet end 4 and a wine outlet end 5, the wine outlet pipe 3 is connected to the wine outlet end 5, the ball core 2 is located in the valve body 1, the valve body 1 is connected to a control component that drives the ball core 2 to rotate to realize the opening and closing of the wine inlet end 4 and the wine outlet end 5, the wine inlet end 4 is connected to a straight tube-shaped branch pipe 6, a diverter core 7 is arranged in the branch pipe 6, and the branch pipe 6 is connected to a connecting pipe 8, the diverter core 7 has a tapered section 71 and a cylindrical section 72, the connecting pipe 8 has a tapered inner wall 81 matched with the tapered section 71, the cylindrical section 72 has a penetration portion 721 axially penetrated in the branch pipe 6, and the outer wall of the penetration portion 721 is embedded with a seal on The sealing ring 19 is on the inner wall of the branch pipe 6, and the cylindrical section 72 has a wine inlet blind hole 722 connected to the wine inlet end 4. The conical section 71 is radially penetrated by six wine inlet through holes 711 circumferentially evenly distributed and connected to the wine inlet blind hole 722 at the inner side of the conical section 71 near the cylindrical section 72. The cylindrical section 72 is sleeved with a sealing ring 2 10 sealed on the inner wall of the branch pipe 6. The cylindrical section 72 is fixedly connected with a fastener 11 located between the sealing ring 1 9 and the sealing ring 2 10. The branch pipe 6 has a slide groove 61 for the fastener 11 to radially pass through. The fastener 11 slides along the slide groove 61 to drive the diverter core 7 to move along its axial direction to change the opening size between the conical section 71 and the conical inner wall 81 to adjust the wine inlet flow rate.

[0030] In the present adjustable flow beer faucet, the valve body 1 and the branch pipe 6 are connected, so that the ball core 2 is assembled with the valve body 1 first, and the assembly is convenient; during processing, the dimensional accuracy of the slide groove 61 must be ensured, that is, when the fastener 11 abuts against one end of the slide groove 61, the tapered section 71 and the tapered inner wall 81 abut to make the wine flow rate zero, and when the fastener 11 abuts against the other end of the slide groove 61, the opening between the tapered section 71 and the tapered inner wall 81 is the largest, and the wine flow rate is the largest. Because the processing difficulty of the slide groove 61 is much smaller than the processing difficulty of the hole distance and the eccentrically arranged spherical protrusion, the present adjustable flow beer faucet is easy to process and has a high yield rate; when in use, by adjusting the fastener 11 The position in the slide groove 61 is used to adjust the flow rate of the wine inlet, which is convenient to adjust. The beer entering from the pipe 8 passes between the tapered inner wall 81 and the tapered section 71, and enters the wine inlet blind hole 722 from the wine inlet through hole 711, and then flows to the wine inlet end 4. The sealing ring 1 9 and the sealing ring 2 10 ensure the sealing performance to avoid leakage, and also provide damping, so that the diverter core 7 is not affected by the impact of the beer and axial displacement. The ball core 2 is driven to rotate by the control component, so that the wine inlet end 4 and the wine outlet end 5 are connected. The beer passes through the ball core 2 and then flows out from the wine outlet end 5. After use, the control component drives the ball core 2 to rotate again to disconnect the wine inlet end 4 and the wine outlet end 5. In this embodiment, the number of sealing rings 1 9 is two, which plays a double sealing role. The fastener 11 is a screw. In actual manufacturing, the fastener 11 can be a cylindrical pin.

[0031] To further elaborate, in this embodiment, the chute 61 is tilted, the fastener 11 is in contact with the two groove walls of the chute 61, one end of the chute 61 is close to the side of the connecting piece 8, and the other end of the chute 61 is close to the side of the valve body 1. After adjusting the flow, the fastener 11 is located in the chute 61, and the diverter core 7 is subjected to the impact force of the beer, which will generate an axial force on the fastener 11. Because the chute 61 is tilted, the groove wall of the chute 61 has a supporting effect on the fastener 11, and the friction damping of the sealing ring 1 9 and the sealing ring 2 10 can further offset the impact force of the beer, avoid the diverter core 7 from being impacted by the beer and causing axial displacement, and ensure the accuracy of flow regulation. In this embodiment, the lower end of the slide groove 61 is close to the valve body 1 side, and the upper end of the slide groove 61 is close to the connecting piece 8 side. When the fastener 11 abuts against the upper end of the slide groove 61, the conical section 71 and the conical inner wall 81 abut against each other to make the wine inlet flow rate zero. When the fastener 11 abuts against the lower end of the slide groove 61, the opening between the conical section 71 and the conical inner wall 81 is the largest, and the wine inlet flow rate is the largest.

[0032] The cylindrical section 72 is sleeved with a sleeve 12, and the fastener 11 is arranged through the sleeve 12, and the outer wall of the sleeve 12 contacts the inner wall of the branch pipe 6. The sleeve 12 provides rotation damping, so that the cylindrical section 72 rotates smoothly and the operation feels comfortable, and can further eliminate the impact force of beer, and prevent the shunt core 7 from axial displacement due to the impact of beer. The sleeve 12 is made of polytetrafluoroethylene material, which has good damping, good wear resistance, and long service life. In actual manufacturing, the end of the sleeve 12 contacts the sealing ring 10, and the conical section 71 intersects with the end of the cylindrical section 72 for the other side of the sealing ring 10 to contact, which is convenient for positioning the sealing ring 10 and assembly.

In this way, the handwheel ring 14 is placed outside to cover the nylon ring 13 and the fastener 11, which has a beautiful appearance. In addition, the nylon ring 13 increases the damping feeling, rotates smoothly, and improves the comfort of the operating feel. When in use, the handwheel ring 14 is rotated, and the handwheel ring 14 drives the nylon ring 13 to rotate between the two limiting convex rings 62. The nylon ring 13 contacts the end of the fastener 11 through the groove wall of the groove 131, driving the fastener 11 to slide along the sliding groove, thereby driving the shunt core 7 to axially displace; the groove 131 is axially extended to provide a clearance space, and the end of the fastener 11 is smoothly displaced.
