Description

Technical Field

[0001] The utility model relates to the technical field of valve faucets, in particular to a sealing ring pressing device for valve faucets. Background Art

[0002] A valve is a device that allows the medium (liquid, gas, powder) in pipes and equipment to flow or stop and control its flow rate. A valve is a control component in a fluid conveying system with functions such as shutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valve to various valves used in extremely complex automatic control systems.

[0003] For example, Chinese patent authorization announcement No. CN216267712U discloses a sealing ring pressing device for a valve faucet, comprising: a top cover, a support column, a pressing component, a motor, a fixing plate, a hydraulic oil pump, a telescopic rod, a slow-release pad, a limit shell, an external pressing ball, a connecting rod, an inner pressure plate, a transmission rod, a limit plate, a bearing ball, an inner pressure column, a spring, a lower pressure seat, an inner pressure rod, a rubber pad, a vent groove and a bottom shell. The support column is installed on the lower end surface of the top cover, and the pressing component is installed on the lower end surface of the support column. Fixed plates are installed on the left and right ends of the middle position of the motor, and hydraulic oil pumps are installed on the left and right sides of the fixing plate. The telescopic rod is installed on the lower end surface of the hydraulic oil pump. Compared with the prior art, the utility model has the following beneficial effects: by using the hydraulic oil pump, the sealing ring can be pressed, and by using the external pressing ball, the sealing ring can be pressed with uniform force, thereby improving the pressing effect of the utility model;

[0004] By referring to the above comparative documents, it can be seen that the existing technology still has the following deficiencies. Since there are many types of valve faucets, the sizes of sealing rings used in different types of valve faucets may also be different, but the existing pressing device can generally only press sealing rings of one size. Therefore, when faced with sealing rings of various sizes, the existing pressing device is difficult to press sealing rings of various sizes, resulting in poor applicability of the existing pressing device. Moreover, when the pressing device presses the sealing ring in the valve, the pressing device is likely to scratch the inner wall of the valve, which may cause damage to the valve. Utility Model Content

[0005] The utility model provides a sealing ring pressing device for a valve faucet, which is conducive to pressing sealing rings of various specifications and sizes and is conducive to preventing the pressing device from scratching and damaging the inner wall of the valve.

DETAILED DESCRIPTION

[0024] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0025] like Figure 1-3 As shown, in this embodiment, it includes an operating handle 1, and pressure rollers 10 are provided on both sides of the lower end of the operating handle 1. Adjustment plates 9 are provided on the inner sides of the pressure rollers 10. A bidirectional threaded adjustment rod 8 is threaded through the two adjustment plates 9, and a mounting block 6 is rotatably sleeved on the middle part of the outer periphery of the bidirectional threaded adjustment rod 8. An electric telescopic shaft 4 is provided above the mounting block 6, and the power end of the electric telescopic shaft 4 is connected to a drive motor 5. The upper end of the mounting block 6 is connected to the power end of the drive motor 5, and elastic buffer components are provided between the adjusting plates 9 and the pressure rollers 10. A battery box 2 is fixed to the middle part of the lower end of the operating handle 1, and a battery 3 is installed in the battery box 2. The upper end of the electric telescopic shaft 4 is fixed to the middle part of the lower end of the battery box 2. A first switch 15 is installed at the left end of the operating handle 1, and the battery 3, the first switch 15 and the electric telescopic shaft 4 are connected in series. A second switch 16 is installed at the right end of the operating handle 1, and the battery 3, the second switch 16 and the drive motor 5 are connected in series.

[0026] When the sealing ring in the valve is pressed by the pressing device, the operating handle 1 is held and pressed down, and then the electric telescopic shaft 4 is controlled to extend through the first switch 15 until the pressure roller 10 can be pressed onto the sealing ring, and then the drive motor 5 is started through the second switch 16. The drive motor 5 will drive the mounting block 6, the two-way threaded adjustment rod 8, the elastic buffer assembly and the pressure roller 10 to rotate together, so the pressure roller 10 will rotate and press the sealing ring during rotation. In summary, through the extension and retraction of the electric telescopic shaft 4, the pressure roller 10 can be conveniently extended into valves of various depths to press the sealing ring, and the operation of the drive motor 5 drives the pressure roller 10 to rotate and press the sealing ring, which effectively ensures the convenience of the sealing ring pressing operation.

[0027] like Figure 1 、 3As shown, in this embodiment, an adjustment plate 9 is provided on the inner side of the pressure roller 10, and a bidirectional threaded adjustment rod 8 is threadedly passed through the two adjustment plates 9. A mounting block 6 is rotatably sleeved on the middle part of the outer periphery of the bidirectional threaded adjustment rod 8. A telescopic rod 7 is connected between the adjustment plate 9 and the mounting block 6, and handles are fixed to the left and right ends of the bidirectional threaded adjustment rod 8.

[0028] When it is necessary to adjust the working distance between the two pressing rollers, the bidirectional threaded adjustment rod 8 is turned by the handle to drive the adjustment plate 9 to compress or stretch the telescopic rod 7. At the same time, the adjustment plate 9 drives the elastic buffer assembly and the pressing roller 10 to move together, so that the working distance between the two pressing rollers 10 can be easily adjusted. Therefore, the cooperation of the two pressing rollers 10 is conducive to the pressing of sealing rings of various sizes, effectively improving the applicability of the pressing device.

[0029] like Figure 2 、 3 As shown, in this embodiment, the outer side surface of the pressure roller 10 is rotatably connected to a plurality of balls 14, and the elastic buffer components include a spring buffer rod 12 and a buffer plate 11. The spring buffer rod 12 is fixed to the outside of the adjustment plate 9, and the buffer plates 11 are connected to the ends of the spring buffer rod 12. The pressure rollers 10 are rotatably connected to the outside of the adjacent buffer plates 11.

[0030] When the pressure roller 10 rotates and presses the sealing ring in the valve, the ball 14 rolls along the inner wall of the valve, and combined with the elasticity of the spring buffer rod 12, it helps to reduce the friction generated on the inner wall of the valve, thereby preventing the pressing device from scratching and damaging the inner wall of the valve when pressing the sealing ring, effectively ensuring the practicality of the pressing device.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementation schemes of the present invention. In addition, other implementation schemes are also included. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
