Description
Technical field:
The utility model relates to air-conditioning technical field, in particular to a kind of sealing device for heat exchanger.
Background technology:
Heat exchanger, is the equipment that the part heat of hot fluid is passed to cold fluid, claims again heat exchanger.Wherein, knockout is one of important auxiliary equipment in Tube Sheet of Heat Exchanger group loop, as shown in Figure 1, knockout of the prior art comprises: offer tap hole 104 knockout main body 10, be welded on separating tube 50 in the tap hole 104 of knockout main body 10, be screwed onto the nut 20 in knockout main body 10.
At present, heat exchanger product all needs to carry out the Check processing of product leakage, traditional handicraft adopts entrance end welding shrouding or capping processing, as shown in Figure 1, between described knockout main body 10 and nut 20, sealing device as described below is installed: be arranged on the weld-ring 90 between knockout main body 10 and nut 20, with the adapter 80 that weld-ring 90 is welded, one end of described adapter 80 is set with sealing ring 70, and the other end of described adapter 80 is welded with shrouding 81.Although above-mentioned sealing device can carry out line seal in heat exchanging organ pipe group loop,, its weak point is: increase the time that product is reprocessed, stopped a leak, reduced production and processing efficiency; The increase of solder joint, also can improve the slip of product greatly; Change the outward appearance of knockout, caused the aesthetic property of product to decline.
Utility model content:
The technical problem that the utility model solves: heat exchanger product is in the time carrying out the Check processing of product leakage, what traditional handicraft adopted seals at import and export end welding shrouding or capping heat exchanger, cause the time that product is reprocessed, stopped a leak to increase, the raising of product leakage rate; The decline of product aesthetic property.
The utility model provides following technical scheme: a kind of sealing device for heat exchanger, comprise knockout, seal member, the nut that described knockout comprises knockout main body, is spirally connected with knockout main body, described seal member is arranged between knockout main body and nut, and described seal member is seal cover.
The novel seal parts of using when the utility model provides a kind of Check processing in heat exchanger product leakage, it is seal cover, than sealing device of the prior art, although seal cover is simple in structure, but, it is easy for installation, and fast and effeciently line seal is carried out in heat exchanging organ pipe group loop, thus the convenient Check processing that product is leaked.Moreover, described seal cover can also play protective action when client sprays paint processing to product.By technique scheme of the present utility model, heat exchanger product is in the time carrying out the Check processing of product leakage, do not need the encapsulation process of as conventional art, capping and shrouding being welded in pipe group loop, so, reprocess, stop a leak in saving in the time, do not change the outward appearance of knockout, greatly improved the aesthetic property of product, solve the technical problem existing in prior art, there is useful technique effect.
As further improvement of the utility model, described nut is provided with back-up ring, and described seal cover is clamped between the end face and back-up ring sidewall of knockout main body.Nut screwing is in knockout main body, and the back-up ring sidewall of nut and the end face of knockout main body are clamped in seal cover wherein, to improve the stability of seal cover.
As further improvement of the utility model, a side of described seal cover is provided with boss, described boss and back-up ring inwall interference fit; The opposite side of described seal cover is also provided with boss, described boss and knockout main body inner wall interference fit.So improve, in the time that nut and knockout main body are spirally connected, the sealing in seal cover heat exchanger loop is improved.
As further improvement of the utility model, be provided with boss with the boss of knockout main body inner wall interference fit, described boss and knockout main body inner wall matched in clearance.That is, be provided with second segment boss with the boss of knockout main body inner wall interference fit, this second segment boss has guide effect, to guarantee that seal cover sleeve is in knockout main body.
As a kind of restriction of the present utility model, above-mentioned seal cover material is polytetrafluoroethylene (PTFE).
Described knockout, except comprising knockout main body, nut, also comprises separating tube, and described knockout main body offers tap hole, and described separating tube is welded in tap hole.
