Embodiment Construction

[0025] The present disclosure will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0026] figure 1 It is a high temperature and high pressure resistant sealing cylinder according to an embodiment of the present invention. Such as figure 1 As shown, the sealed cylinder includes a cylinder main body 1, an upper flange structure 2, an air inlet 4, an air outlet 5, a pressure measurement conduit 8, a thermocouple 7, a drain pipe 6 and a sealing gasket 3, and the two ends of the cylinder 1 are arranged For the lower flange structure.

[0027] Both ends of the cylinder body 1 are provided with sealing gasket grooves with a diameter greater than the inner diameter of the cylinder body 1. The sealing gaskets 3 are placed on the sealing gasket grooves. The sealing gaskets 3 are composed of stainless steel sheets and rubber sheets arranged alternately. In the above embodiment, stainless steel sheets and rubber sheets are alternate...

Abstract

The invention discloses a sealing cylinder, which comprises a cylinder body, a cover part, a sealing device, a temperature measurement device and a pressure measurement device. An air inlet and an airoutlet are formed in a side wall of the cylinder body; the cover part seals openings in the first end and the second end of the cylinder body; the sealing device is arranged between the cylinder bodyand the cover part; the temperature measurement device and the pressure measurement device penetrate through the cover part and the sealing device to arrive at the inner part of the cylinder body. The invention discloses the sealing cylinder, which can well simulate a high-temperature high-pressure environment, can be used for concretely monitoring temperature and pressure of a test object in real time, and has good high pressure resistance and good sealability.

Description

technical field [0001] The disclosure relates to a sealing cylinder, in particular to a high temperature and high pressure resistant sealing cylinder. Background technique [0002] The core of the reactor is composed of the arrangement and combination of fuel elements, including cladding and surrounding radioactive fuel pellets. Therefore, the performance of the fuel cladding plays a vital role in the safety of the reactor. Before the fuel cladding is put into use, it is necessary to test the high temperature and high pressure resistance of the cladding under abnormal conditions (loss of water accident conditions) to ensure the safety of the reactor in the event of an accident. The detection of the cladding needs to be carried out in a special high temperature and high pressure resistant sealed cylinder. But at present, there is no sealed cylinder in the prior art that can well meet the safety performance test requirements of the fuel cladding of the current reactor under ...
