The structure for pressure test of a kind of heat interchanger package of the present utility model, because it is provided with O-ring seal, therefore when pressure testing is tested, by crush seal circle when structure for pressure test is connected by screw thread with heat exchanger shell, thus reach the effect of sealing, realize the impermeability of the connection of structure for pressure test and heat interchanger package.Remove raw material band when being wound around raw material band and dismounting structure for pressure test before therefore not needing that structure for pressure test is installed, save operation, cost-saving.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of one of them embodiment of structure for pressure test of heat interchanger package of the present utility model.
The structure for pressure test that Fig. 2 is the heat interchanger package shown in Fig. 1 removes the schematic front elevation view after input adapter.
Fig. 3 is the schematic cross sectional views of Fig. 2 shown device.
Embodiment
Followingly carry out exemplary description to the utility model, the identical label of wherein identical parts represents.
Fig. 1 is the schematic diagram of the structure for pressure test of a kind of heat interchanger package of the present utility model.With reference to figure 1, wherein, this structure for pressure test comprises main body 10 and is positioned at the input adapter 20 of this main body 10 side circumference distribution.Wherein, 10 one end of this main body have itself and then the external thread 11 structure for pressure test being connected to heat interchanger package, and the relative other end is processed to the sexangle of hexagon or similar nut, are convenient to install and dismounting.
Input adapter 20 can be existing fluorinfused nozzle, and such as R22 fluorinfused nozzle etc., because its structure is existing structure, are not described in detail in this.This input adapter 20 is arranged in the hole 12 (with reference to figure 2) of main body 10, and it is inner and extraneous that hole 12 is communicated with heat interchanger package, therefore refrigerant (such as freon etc.) can be injected in heat interchanger package by input adapter 20.Input adapter is corresponding with hole.Preferably, for placing the hole 12 of input adapter 20, can be two.Preferably, this hole 12 can be 3, and as shown in Figure 2, one of them can as hole for subsequent use, easy to use in its distribution.
With reference to figure 2, for the purpose of clear, only show the schematic front elevation view removing the rear structure for pressure test of input adapter 20.As shown in the figure, this hole comprises the first hole portion along main body 10 axis and the second hole portion along main body 10 radial direction, and described first hole portion communicates with the second hole portion.3 hole common axises to the first hole portion, and the second hole portion is uniformly distributed in this main body 10 external circumferential.In the second hole portion in 3 holes, input adapter 20 (as shown in Figure 1) is respectively set.Because this structure for pressure test has hole for subsequent use and input adapter, therefore when certain input adapter breaks down, hole for subsequent use and input adapter can be selected, the normal use of this structure for pressure test can not be affected.
The part being provided with the second hole portion of the main body 10 of this structure for pressure test can be positive hexagon (as shown in Figure 1 or 2), is convenient to processing.120 degree, second interval, hole portion in 3 holes, is circumferentially evenly arranged in the main body side of positive six prisms.When only having 2 holes, arranging of its hole can the setting in similar above-mentioned 3 holes.
Fig. 3 is the schematic cross sectional views of the structure for pressure test of the heat interchanger package shown in Fig. 2, wherein demonstrates the annular groove 13 of main body 10 adjacent threads end, and is positioned at O-ring seal 30 wherein, also demonstrates the setting in the hole 12 of this structure for pressure test.In prior art, for guaranteeing the sealing that structure for pressure test is connected with heat exchanger shell, usually needing external thread outer felt at structure for pressure test around raw material band, after test terminates, also needing to remove the raw material band be wound around.And structure for pressure test of the present utility model arranges annular groove 13 (as shown in Figures 2 and 3) at close external thread 11 place of main body 10, O-ring seal 30 (with reference to figure 3) is placed in annular groove 13, the impermeability of this connection can be guaranteed when structure for pressure test is connected with heat interchanger package, avoid using raw material band, thus saving operation, cost-saving.
As shown in Figure 3, this main body 10 is structure as a whole, and such as adopt the direct machine work of round steel to form, this integral structure, can improve the safe reliability of this structure for pressure test.Sealing circle 30 can be O type rubber seal.
In use, spanner or aerodynamic wind big gun can be utilized to be connected on heat interchanger package by structure for pressure test of the present utility model, O-ring seal compressive deformation, thus make this connection keep sealing.
Above, heat interchanger can be evaporator in field of air conditioning or condenser.
The above embodiment only have expressed preferred implementation of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
