Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and more specifically to a high-efficiency cambered sealing valve for compressors and a manufacturing device thereof. Background Art

[0002] Compressors are widely used in many industrial fields, and the performance of their valve components has a critical impact on the working efficiency, energy consumption and service life of the compressor. In terms of working efficiency, the quality of valve performance is like a double-edged sword, which directly determines the operating efficiency of the compressor. An efficient valve can ensure that the flow path of gas in the compressor is unobstructed, just like building a high-speed channel for the gas. During the suction stroke, it can open at the right time and degree, allowing the gas to quickly flow into the compression chamber like a tide, so that the compression process can be carried out fully and efficiently; and during the exhaust stroke, it can be closed in time like a precise gate to prevent the backflow of compressed gas, thereby ensuring that each compression cycle can output the maximum amount of effective work, so that the working efficiency of the compressor reaches the ideal state.

[0003] However, most of the existing sealing valves are flat seals, which are prone to uneven wear of the sealing surface due to vibration and pressure fluctuations, poor sealing and a vicious cycle of wear, requiring large sealing force, increasing maintenance costs and downtime frequency, and their flow channels are simple, impurities are easily accumulated in narrow corners, causing a sharp increase in flow resistance, a sharp drop in efficiency, and damage to the flow channels.

[0043] Embodiment 2, as Figure 4 As shown, the present invention relates to a manufacturing device for a high-efficiency cambered sealing valve for a compressor, comprising a mechanical arm 5, the end of the mechanical arm 5 is connected to one side of the top end of a lateral moving assembly 6, and the lateral moving assembly 6 rotates in a horizontal plane with the end of the mechanical arm 5 as the axis, and both output ends of the lateral moving assembly 6 are installed with milling assemblies 7, and the milling assembly 7 is provided with a ball-end milling cutter 704, and the ball-end milling cutter 704 rotates in a horizontal plane with the end of the mechanical arm 5 as the axis, and the rotation tracks of the two ball-end milling cutters 704 are concentric and radially distributed;

[0044] Working method: the robot arm 5 drives the lateral moving component 6 to rotate in a horizontal plane with the end of the robot arm 5 as the axis. When the lateral moving component 6 rotates, it drives the milling component 7 to rotate. The milling component 7 drives the ball end mill 704, and the ball end mill 704 processes the sealing groove 101 and the arc surface 103.

[0045] The present invention is provided with two concentric and radially distributed milling assemblies 7, so that the two milling assemblies 7 can rotate along the end of the mechanical arm 5 as the axis, forming two concentric and radially distributed rotating tracks, which is convenient for processing the valve seat 1, and the arc surface 103 structure can be processed by using the ball end mill 704. The present invention can form the concentric and radially distributed sealing groove 101 structure and the sealing groove 101 arc surface 103 at one time, which not only has high processing accuracy and excellent molding quality, but also greatly reduces the processing procedures and time, significantly improves the overall work efficiency, and effectively enhances the production efficiency and product competitiveness.
