A type of valve for spherical materials

Abstract

The invention relates to the field of flow resisting and conveying equipment and provides a valve used for spherical material. A laser comprises a fixing sleeve, a sliding execution member and a driving unit. The fixing sleeve is transversely provided with a slideway in a penetrating manner. The top surface and the bottom surface of the fixing sleeve are equipped with a sphere inlet hole channel and a sphere outlet hole channel, both of which communicate with the slideway. Additionally, the sphere inlet hole channel and the sphere outlet hole channel do not share the same axis. The sliding execution member is arranged in the slideway in an inserting manner and axially equipped with a sphere passing through hole in a penetrating manner. The sliding execution member is connected with the driving unit. The driving unit is used for driving the sliding execution member to slide in the length direction of the slideway such that the sphere passing through hole communicates with the sphere inlet hole channel or the sphere outlet hole channel. The valve used for spherical material is simple in structure and convenient in operation. Spherical material can be conveyed intermittently and quantitatively. Additionally, a flow resisting area is located at the sphere inlet hole channel and the sphere outlet hole channel. Therefore, fault tolerance of movement is high. The flow resistance is fully reliable.

Description

technical field [0001] The invention relates to the field of blocking flow conveying equipment, in particular to a similar valve for spherical materials. Background technique [0002] The pebble bed high temperature gas-cooled reactor uses its unique fuel loading and unloading system to continuously perform loading and unloading, circulation, transportation and temporary storage of spherical fuel elements, so that the continuous operation of the high temperature reactor can be realized, thereby ensuring the availability and economical efficiency of the nuclear power plant. sex. It can be seen that the fuel loading and unloading system is the key equipment to ensure the continuous operation of the pebble bed high temperature gas-cooled reactor. [0003] At present, the fuel loading and unloading system mainly adopts two methods of self-weight flow of spherical fuel elements and pneumatic conveying of compressed gas to transport spherical fuel elements. In order to ensure th...

[0004] Chinese invention patent CN201410036427.7 discloses a choke used in a high-temperature gas-cooled reactor. The choke includes power components, a magnetic drive, a box assembly, and a rotor assembly. It needs to be rotated once, but under severe conditions such as high temperature, strong radioactivity, falling vibration of spherical fuel elements, high-frequency operation and changes in bearing clearance, after long-term operation, the friction between the rotor assembly and the box assembly will continue to intensify, even It will cause the rotor assembly to run eccentrically, which will affect the normal pneumatic conveying and the circulation, loading and unloading of spherical fuel elements
