Problems solved by technology

[0003] In the prior art, a manual distributor with a pneumatic piston structure has similar functions, but it needs to preset the ball flow communication channel, and cannot automatically turn and distribute continuous or discrete ball flow in real time, and is only suitable for occasions with few actions
In addition, similar functions can also be performed by using some turning and conveying devices. The rotor of the device is provided with two ball receiving cups arranged at 120°. Through the control of the rotation angle, the discrete delivery of the single-way ball flow to the two pipelines can be realized. For the tandem spherical elements conveyed in the same direction continuously, the device needs to be started and stopped frequently, and there is inevitably a risk of ball jamming, so it is not suitable for the continuous implementation of the "one-to-two" ball flow distribution function

Embodiment 1

[0054] The embodiment of the present invention proposes a right steering gear applied to a high-temperature gas-cooled reactor based on a packing shaft seal, see figure 1 , the high-temperature gas-cooled reactor steering gear involved in the present invention includes a power component 1, a coupling assembly 2, a shaft seal connection assembly 3, a rotor assembly 5 and a casing assembly 6, wherein the shaft seal connection assembly 3a is a middle flange 4 is the middle flange connection assembly of the main body.

[0055] see figure 1 and figure 2 The shaft seal connection assembly 3a is composed of the bracket 10 and the middle flange 4 to form the connection body. The middle flange 4 has sufficient thickness, which can effectively prevent the spherical element from causing damage to the power component 1 due to axial accumulation and continuous radiation. The rotor includes a rotating drum 19 and a rotating shaft 29. The rotating drum 19 is placed in the sealed space for...

Embodiment 2

[0058] The embodiment of the present invention proposes a left steering gear applied to a high temperature gas-cooled reactor based on a magnetic drive without a shaft seal, see Figure 4 , The high temperature gas-cooled reactor steering gear involved in the present invention includes a power component 1, a coupling assembly 2, a shaft seal connection assembly 3, a rotor assembly 5 and a box assembly 6, wherein the shaft seal connection assembly is a magnetic drive 3b.

[0059] see Figure 4 and Figure 5 , The configuration and structure of the power component 1, the coupling assembly 2, the rotor assembly 5 and the box assembly 6 are the same as those in Embodiment 1, and the positional relationship and connection mode of each component are also basically the same. However, since this embodiment adopts the magnetic drive 3b as the shaft seal connection assembly, it is suitable for the seal transmission in the helium atmosphere. The isolation cover 37 of the magnetic drive...

Abstract

The invention provides a steering gear applied to a high temperature gas cooled reactor. The steering gear comprises a box body component, a power component, a shaft seal connecting component and a rotor component, wherein the shaft seal connecting component also having the function of steering shielding is arranged; the box body is provided with a first straight through hole and a first side through hole; the rotating drum of the rotor is provided with a second straight through hole and a second side through hole; the inclined angles of the axle of the second straight through hole and the second side through hole is equal to the included angle of the axle of the first straight through hole and the first side through hole, so that a straight through ball path and a side through ball path which can be mutually switched according to rotation of the rotor are formed. The steering gear has the function of ball flow distribution that one is divided into two, is simple in structure and small in pipeline mounting space, and the requirements on reliability in long-term operation in a strong radiation working environment are met.

Description

technical field [0001] The invention relates to reactor engineering, in particular to a diverter applied to a high-temperature gas-cooled reactor. Background technique [0002] The pebble bed high-temperature gas-cooled reactor uses spherical fuel elements (hereinafter referred to as spherical elements) to run through the core multiple times. The availability and economy of high-temperature reactor nuclear power plants largely depend on their unique fuel loading and unloading systems. Chinese invention patent CN101083153B discloses a pebble bed modular high-temperature gas-cooled reactor fuel loading and unloading system for on-line refueling. Since it is necessary to charge the dual-reactor cores from a common charging subsystem, and for a single reactor, it is also necessary to Different types of spherical elements, such as enrichment elements, low-enrichment elements, graphite balls, and spent fuel balls, are identified or differentiated and sent to different pipelines, o...
