Problems solved by technology

Under normal circumstances, the temperature in the sealed working space continues to rise during the period when the channel has not been opened, which will cause significant overheating
[0007] In addition, when the ambient temperature, or rather, when the temperature of the closed cavity shell is significantly lower than the cavity temperature, the start-up lag will be further prolonged
In this case, the molten solder in the entire bolt body is affected by the external low temperature, which is not conducive to melting

Embodiment Construction

[0047] A best embodiment of the present invention will be described below with reference to FIGS. 2 to 4 .

[0048] figure 1 Shown is a closure representing the state of the art. It can be seen that the closure has a closure body 1 in which a channel 1 . 1 is provided which is closed with a fuse element 2 . The fuse element is a melting solder, which is placed in the channel 1.1 over its entire cross-section and exhibits a great thickness.

[0049] Also in Figure 4a with Figure 4b Also shown is a closure representing the state of the art for installation in fluid couplings. Such a closure in a hydraulic coupling has a certain start-up hysteresis, resulting in an overtemperature of the working medium of about 50K, which is related to the heating rate of the working medium. This means that the temperature of the fluid coupling working medium is about 50K higher than the rated temperature of the welding solder.

[0050] Figure 2 shows a closure according to the invention,...

Abstract

A closure with the function of a thermal fuse, comprising a closure body that closes a cavity that needs to be closed; a fuse element inserted in the closure body, and a passage provided in the closure body that can be at least indirectly closed; The invention also includes a bolt which is inserted into the through hole of the closure body and closes the through hole; the fuse element interconnects the bolt and the closure body; the closure of the present invention may also comprise a through hole A sleeve and a bolt, wherein the bolt is inserted into the through hole of the sleeve and closes the through hole, and the fuse element connects the sleeve and the bolt to each other. The sealing member with the function of a thermal fuse provided by the invention has short start-up time and reliable opening function, and is suitable for sealing the working space of a fluid power flow energy machine, especially a working space of a hydraulic coupling.

Description

technical field [0001] The invention relates to a closure with the function of a thermal fuse, in particular, the invention relates to a hydrodynamic machine for converting the energy of water flow into mechanical energy, the working space of which is sealed by means of a closure with the function of a thermal fuse , isolated from the surrounding environment. Background technique [0002] Closures having the function of a thermal fuse are already known. Such a closure contributes to cavity sealing, eg against the environment, which media will satisfy the hydrodynamic working space and be closed. Typically, the seal is mounted in a box which directly forms a cavity or at least indirectly encloses a cavity. The closure is combined with heat conduction in the cavity, for example containing a liquid working medium. [0003] The significance of the function of the thermal cutout is that the temperature of the seal depends on the temperature in the cavity and opens automaticall...
