Embodiment
Below by drawings and Examples, technological scheme of the present invention is described in further detail.
Fig. 1 is one-way valve embodiment's of the present invention plan view, Fig. 2 is one-way valve embodiment's of the present invention right elevation, Fig. 3 is one-way valve embodiment's of the present invention left view, Fig. 4 is a shape schematic representation of the stage clip of one-way valve of the present invention, Fig. 5 is that the stage clip of one-way valve of the present invention is in the left view under the normal state, Fig. 6 is the stage clip of one-way valve of the present invention left view under in running order, Fig. 7 is a shape schematic representation of the reed of one-way valve of the present invention, Fig. 8 is in left view under the normal state for the stage clip of one-way valve of the present invention, and Fig. 9 is the left view of the stage clip of one-way valve of the present invention under in running order.Shown in Figure 9 as Fig. 1, one-way valve of the present invention comprises: comprise dunnage 1, a side of dunnage 1 is installed with reed 2, stage clip 3 and the carriage 4 that metallic material is made successively;
Wherein, reed 2 comprises reed body 21 and is arranged on being used on the reed body 21 and be blocked in airtight plate 22 on a plurality of inlet holes 11 on the dunnage 1, and stage clip 3 comprises stage clip body 31 and is arranged on being used on the stage clip body 31 and pushes up the compressing tablet 32 that is located on each airtight plate 22; Offer vent in the middle of dunnage 1 and the carriage 4, vent is equipped with rivet 6, and rivet 6 is installed on the carriage 4, and rivet 6 is arranged with washer 7, and catch 7 is positioned at the opposite side of dunnage 1, and is blocked in the vent 12 of dunnage 1, and is arranged with spring 8 on the rivet 6; Spring 8 is between the end of catch 7 and rivet 6;
When vent 12 fed refrigerant, airtight plate 22 broke away from inlet hole 11 under the refrigerant differential pressure action, make refrigerant pass through inlet hole 11; When vent fed refrigerant, washer 7 moved on rivet 6 at promotion spring 8 under the refrigerant differential pressure action, makes refrigerant pass through vent.
The one-way valve that the embodiment of the invention provides, the reed 2 by adopting metallic material to make has improved the resetting property of reed 2 and the validity that installs stage clip 3 additional, thereby reed 2 is effectively sealed.
Further, carriage 4 is provided with supporting frame 41, and rivet 6 is installed on the supporting frame 41.
Further, dunnage 1 is provided with at least three positioning boss, is provided with the locating slot 5 that is set on the positioning boss on reed 2, stage clip 3 and the carriage 4.
Further, when the thickness of stage clip 3＞0.1mm, one-way valve can not be realized effective unlatching under the pressure reduction of regulation, and flow can not meet product requirement; When the thickness of stage clip 3＜0.03mm, stage clip 3 circles are bent, and to act on the power of reed 2 too small, can not realize the closure of stage clip 3, and interior leakage can not meet product requirement; Therefore, the thickness of the stage clip 3 in the embodiment of the invention is 0.03mm～0.08mm, thereby makes that one-way valve can proper functioning; Further, if angle＜120 of stage clip body 31 and compressing tablet 32 °, behind valve opening, reed can not normally reset; If angle＞150 of stage clip body 31 and compressing tablet 32 °, when valve opening a period of time, reseting pressuring spring 3 can't make reed 2 sealings; Therefore, the thickness of the stage clip 3 in the embodiment of the invention is 0.03mm～0.08mm, and stage clip body 31 is 120 °～150 ° with the angle of compressing tablet 32; Preferably, the thickness of stage clip 3 is 0.04mm, and stage clip body 31 is 120 °～130 ° with the angle of compressing tablet 32, and perhaps, the thickness of stage clip 3 is 0.07mm, and stage clip body 31 is 130 °～150 ° with the angle of compressing tablet 32.The design of the thickness by stage clip 3, stage clip body 31 and compressing tablet 32 makes stage clip 3 have elasticity and resetting property.
Further, the press-bending coefficient of stage clip 3 is greater than the press-bending coefficient of reed 2.Further, stage clip 3 in the embodiment of the invention and reed 2 can be processed into the part of one, and the press-bending coefficient of stage clip part is greater than the press-bending coefficient of reed part, and the press-bending coefficient of stage clip part and reed part differs more than 30%.By stage clip and reed are made one, can simplify assembly process, reduce matching requirements.
Further, dunnage 1 also is provided with and is used to a plurality of inlet holes 11 that refrigerant is passed through, the embodiment of the invention is only carried out exemplary illustration so that four holes to be set, the shape of reed 2 and stage clip 3 changes along with the shape of the inlet hole 11 that is provided with on the dunnage 1, as shown in Figure 4 and Figure 5, and carry out exemplary illustration in conjunction with Fig. 1～Fig. 3, evenly offer four inlet holes 11 on the dunnage 1, correspondingly, flow in order to control refrigerant, be provided with four airtight plates 22 on the reed body 21 of reed 2, be provided with four compressing tablets 32 on the stage clip body 31 of stage clip 3 and be used for establishing airtight plate 22 in order to push up.Apparently, when offering a plurality of inlet hole 11 on the dunnage 1, also the number with inlet hole 11 is identical accordingly for the number of airtight plate 22 and compressing tablet 32.
Figure 10 is the plan view of filter embodiment of the present invention, as shown in figure 10, and carry out exemplary illustration in conjunction with Fig. 1～Fig. 9, filter of the present invention comprises: body 61, molecular sieve 62, wherein, be respectively arranged with Fig. 1～one-way valve 64 embodiment illustrated in fig. 9 in two ends of body 61, be provided with filter element 63 between two ends of body 61 and the one-way valve 64.
Further, filter element 63 is made of in turn filter sheet, screen cloth, backstop.
The filter that the embodiment of the invention provides by adopting above-mentioned Fig. 1～one-way valve embodiment illustrated in fig. 9, owing to effective sealing of one-way valve, has improved the open and close valve number of times of one-way valve.
Figure 11 is an embodiment of the invention application schematic representation of refrigerant two-way flow in the course of the work, Figure 11 is in the schematic representation of normal state for the stage clip in the one-way valve of the present invention, as shown in figure 11, and carry out exemplary illustration in conjunction with Fig. 1～Figure 10, when refrigerant when left side one end of filter flows into one-way valve, when refrigerant flows into one-way valve 64, the inlet hole of offering on the dunnage of flowing through 1 11, because refrigerant pressure reduction is opened the reed 2 of one-way valve 64, stage clip 3, and from flowing into molecular sieve 62 inside between carriage 4 and the body 61, and the filter sheet of process filter element 63, screen cloth, backstop flows into the vent 12 that dunnage 1 is offered, because refrigerant pressure reduction promotes the catch 7 of one-way valve 64, the spring 8 that is fixedly arranged on the one-way valve 64 seesaws and realizes opening along rivet 6, refrigerant flows out through vent 12, refrigerant is identical with said process from the right side one end inflow one-way valve of filter, does not repeat them here.
Technique scheme as can be seen, because the reed in the one-way valve of the present invention adopts metal material, improved the resetting property of reed, and be easy to processing, its active force of stage clip assembling back can cover 3/4ths area of reed, thereby guaranteed the sealing of reed and dunnage, improved the working life of one-way valve.
It should be noted last that, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technological scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.
