Description

Technical Field

[0001] The utility model relates to the technical field of speed regulation of low-speed centrifuges, in particular to an arc-shaped magnetically controlled regulating valve applied to a dual-speed motor for a low-speed centrifuge. Background Art

[0002] Low-speed centrifuge equipment is a centrifugal separation equipment that uses low speed and high torque. It can separate different components in a mixture. In order to meet its demand for low speed and high torque, cycloidal motors are often used on the market for driving. In order to adapt to the requirements of various centrifugal separation conditions, cycloidal motors need to set corresponding displacements for different motors. However, the optimal efficiency zone of motor speeds of different displacements is also different, and the regulating valve of the cycloidal hydraulic motor can only simply control the opening and closing, and the control method is relatively simple. It cannot meet the needs of the existing two-speed cycloidal hydraulic motor under different displacement conditions, and the internal resistance is relatively large during speed regulation, making it difficult to achieve optimal efficiency. In addition, the regulating valve of the two-speed motor mainly adopts unidirectional flow diversion, resulting in a relatively concentrated impact force during diversion, and the inflow volume is not uniform, resulting in insufficient sealing of the assembly end and the adjustment end; it is also impossible to exchange the temperature of the inflow fluid through the reflux fluid, resulting in a relatively simple functionality.

In addition, the regulating valve of the two-speed motor mainly adopts unidirectional flow guidance, resulting in a relatively concentrated impact force during the flow guidance, and the inflow volume is not uniform, resulting in insufficient sealing of the assembly end and the adjustment end; it is also impossible to exchange the temperature of the inflow liquid through the reflux liquid, resulting in a relatively simple functionality.

[0021] The arc-shaped upper adjustment cover 2 and the arc-shaped lower adjustment cover 3 are designed with a two-section structure, and the two sections are divided by a central locking frame 4 and then fixed by locking bolts.

[0023] The external liquid inlet pipe 7 is poured into the arc-shaped upper adjustment cover 2 and the arc-shaped lower adjustment cover 3 respectively through the two side arc-shaped guide channels located inside the lateral air guide cover 1, while the external liquid discharge pipe 8 guides the liquid between the arc-shaped guide channels located on both sides to perform heat exchange.
