Embodiment 1

[0049] Such as Figure 1-4 As shown, the present embodiment provides a discharge valve, which includes:

[0050] A valve body 1 with a valve cavity inside, the valve body 1 has an inlet port 11 and an outlet port 12;

[0051] The ball 4 as the opening and closing part is assembled in the valve cavity and is suitable for controlling the on-off of the discharge valve;

[0052]The sphere 4 has a through hole; when the through hole communicates with the valve cavity, the valve body channel is opened; the valve body channel is respectively communicated with the inlet port and the outlet port; the discharge valve also includes, a valve stem 5, which is connected to the ball 4 and drives the ball 4 to open or close the passage of the valve body;

[0053] The radiation shielding cover 3 includes a body 31; a side plate 32, which surrounds the body 31, and one end of the side plate 32 is connected to the body 31 or is integrally made with the body (31), and faces away from the body (...

Embodiment 2

[0070] This embodiment provides a discharge valve. Compared with the discharge valve provided in Embodiment 1, the difference is that the opening and closing part is a gate plate, which is assembled in the valve cavity and is suitable for controlling the opening and closing of the discharge valve. broken.

[0071] Further, a third shielding layer can be embedded in the shutter, and the second shielding layer can be selected as a graphene composite shielding material or a lead-based nuclear shielding material, which can realize that when the discharge valve is closed, the radiation shielding cover Cooperate to form a shielding and sealing cavity at the gate and the outlet of the valve body, which not only ensures that the radioactive liquid will not leak, but also ensures that the radiation will not pass through the above-mentioned shielding and sealing cavity, thereby preventing pollution of the external environment.

Abstract

The invention relates to the technical field of valves, in particular to a discharge valve. A radiation shielding cover capable of opening or closing an outlet end of a valve body is arranged at the outlet end of the valve body, so that when the discharge ball valve discharges materials to a pipeline for receiving a nuclear medium, the radiation shielding cover is opened to make the discharge valve communicate with the pipeline; and when the discharging is completed, due to steam of radioactive substances existing in the pipeline for receiving the nuclear medium, the steam is condensed into liquid in a valve cavity of the ball valve, and when a discharging device is separated from the pipeline, the radiation shielding cover closes the outlet end to prevent radioactive liquid condensed in the valve cavity from contacting with the outside, so that safe discharging is achieved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a discharge valve. Background technique [0002] The valve uses a valve plate or a sphere with a channel as the opening and closing part to operate the opening and closing part to open or close the valve. Its function is to ensure the smooth passage of the medium and ensure the sealing of the valve when the valve is closed. The discharge valve is a valve that controls the connection between the discharge device and the material receiving device. Among them, the discharge ball valve is a common discharge valve. The existing discharge ball valve is mainly improved for the retention of materials at the ball valve. . For example, in the patent document CN202812283U, it reduces the distance between the sphere and the degassing tank, eliminates the dead angle between the degassing tank and the ball valve, eliminates the accumulated material in the dead angle, and completely discharges ...
