Description
Technical field
The utility model relates to technical field of air conditioner refrigeration, is specifically related to a kind of fusible plug assembly.
Background technology
Refrigerant is constantly circulation by itself state change to realize the operation material of refrigeration in refrigeration systems, its by hermetically sealed in air-conditioning system.When as outside fire or air-conditioning system spontaneous combustion occur, due to the sharply rising of temperature, the pressure of refrigerant in confined space suddenly increases, and very easily blasts, thus causes larger destruction to surrounding environment.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of air-conditioning system when there is outside fire or air-conditioning system spontaneous combustion, prevents the fusible plug assembly exploded.
In order to solve the problems of the technologies described above, the technical scheme that the utility model provides is as follows: a kind of fusible plug assembly, and comprise fusible plug and meltable bolt seat, described fusible plug is provided with axially extending bore, fills out and be provided with low-melting alloy in this through hole; Described meltable bolt seat is provided with through hole vertically, and one end and the fusible plug of described meltable bolt seat are sealedly and fixedly connected, other end connecting tubes.
Further, described fusible plug is threaded with meltable bolt seat, and is marked with anaerobic sealer in interconnective screw thread.
Further, also sealing gasket is provided with between described fusible plug and meltable bolt seat.
Further, the fusing point of described low-melting alloy is 70 ± 3 DEG C.
Further, the end of described adapter forms flange through enlarging, and the lower end of described meltable bolt seat is inserted in the adapter of enlarging, and by being welded and fixed.
Further, the lower end of described meltable bolt seat is provided with container cavity, and the end of described adapter to be inserted in this container cavity and by being welded and fixed.
Fusible plug assembly of the present utility model, connected by the refrigerant of adapter with air-conditioning system, when there is outside fire or air-conditioning spontaneous combustion makes temperature higher than safe temperature, filling out the low-melting alloy established in fusible plug and being melted, refrigerant flows out by the axially extending bore of fusible plug, pressure in its seal cavity is quickly released, thus prevents air-conditioning system from exploding, and loss is reduced to bottom line, this fusible plug modular construction is simple, practical, security is good, is suitable for promoting in field of air conditioning.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " on ", D score, "front", "rear", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, connect integratedly, also can be removably connect; It can be the connection of two element internals; Can be directly be connected, also indirectly can be connected by intermediary, for the ordinary skill in the art, concrete condition can understand the concrete meaning of above-mentioned term in the utility model.
embodiment one
As shown in Figure 1, Figure 2, the fusible plug assembly of the first embodiment comprises fusible plug 1 and meltable bolt seat 2, and wherein fusible plug 1 is provided with axially extending bore 4, fills out and be provided with low-melting alloy 5 in this through hole 4.It should be noted that, fill out in the present embodiment the low-melting alloy 5 set as fusing point be the alloy of about 70 DEG C, be commonly called as 70 DEG C of alloys, because the selection of 70 DEG C of alloys is on the market more, belong to existing known materials, therefore do not limit at this concrete material to this low-melting alloy, meeting fusing point is 70 ± 3 DEG C.
Further, meltable bolt seat 2 is provided with through hole 7 vertically, and one end and the fusible plug 1 of its meltable bolt seat 2 are sealedly and fixedly connected, other end connecting tubes 3, and wherein adapter 3 is connected with the refrigerant of air-conditioning system.As preferably, fusible plug 1 is threaded with meltable bolt seat 2, based on sealing requirements, is marked with anaerobic sealer in interconnective screw thread, and is also provided with sealing gasket 6 between fusible plug 1 and meltable bolt seat 2.In this embodiment, the end of adapter 3 forms flange 31 through enlarging, and the lower end of meltable bolt seat 2 is inserted in the adapter 3 of enlarging, and by being welded and fixed.
embodiment two
As shown in Figure 3, the fusible plug assembly of the second embodiment is identical with the fusible plug module body structure of the first embodiment, and difference is the connected mode of meltable bolt seat 2 and adapter 3.In the present embodiment, the lower end of meltable bolt seat 2 is provided with container cavity 8, and the end of its adapter 3 to be inserted in this container cavity 8 and by being welded and fixed.This connected mode is compared with embodiment one, and advantage is that container cavity plays positioning action, and welding procedure is more simple, and manually can complete welding, welding quality also more easily ensures.
The fusible plug assembly of above-mentioned two kinds of embodiments, connected by the refrigerant of adapter with air-conditioning system, when there is outside fire or air-conditioning spontaneous combustion makes temperature higher than safe temperature, filling out the low-melting alloy established in fusible plug and being melted, refrigerant flows out by the axially extending bore of fusible plug, pressure in its seal cavity is quickly released, thus prevents air-conditioning system from exploding, and loss is reduced to bottom line, this fusible plug modular construction is simple, practical, security is good, is suitable for promoting in field of air conditioning.
In a word; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
