Abstract

A service coupling for use with either a push-type or a screw-type port valve of a charge port is provided that includes a body portion and an axially moveable valve housing. Axial movement of an actuator permits both the selective axial movement of the valve housing from a rearward position toward a forward position and the selective disengagement of the port valve to open a flow path. In one embodiment the actuator has a nose portion that engages a threaded port valve, or axially moves a push-pin valve, to open a flow path. The operation is the same with either type of valve such that the user is not required to know which type of valve is present.

The present invention relates to a maintenance coupling for directing coolant from a coolant supply source to a refrigeration system via a filler interface, which is typically attached to the cold; eastern system and the control system Connected. The service coupling can also be used to drain the coolant from a cold roll system. [Previous Technology] Conventional coolants such as fluorocarbons (CFCs) and fluorocarbons (HCFCs) are strictly controlled because they consume ozone in the atmosphere. Exploration of new and environmentally friendly coolants to replace existing CFCs and HCFCs is directed towards the use of hydrofluorocarbons (HFCs) such as R134a. However, compared to natural coolants such as carbon dioxide or Ammonia, HFCs still show a relatively high possibility of global temperature rise (GWP) and a relatively low cost of use. These stakes have stimulated research needs for alternative refrigeration systems that use coolants other than HFCs. Through the development of refrigeration systems using carbon dioxide as a coolant, the industry of automatic air conditioners has begun to address the challenge of replacing HFCs. Used to direct coolant from a coolant supply to an inlet in the cooling system or a "charging" interface to the 200402518 maintenance connector or adapter of a refrigeration system in the related art Is well known. One known service coupler utilizes the property of one or more filler connections that can be quickly connected "to the refrigeration system. Once connected, a service valve in the service coupler engages and activates a valve in the service coupler. An interface valve in the packing interface is used to open a coolant flow path between the packing interface and the couplers. The maintenance valve is generally moved by a rotary knob into the valve connected to the interface valve. In the connection relationship, the knob can be threaded to the coupling. Traditional maintenance couplings such as those used for servicing the R134a automatic air conditioning system are usually designed to reach up to about 100 psi ( 6 · 9 bar). However, refrigeration systems that use carbon dioxide as a coolant are operated at pressures significantly higher than those of ordinary R134a refrigeration systems, that is, higher than 100 psi (6.9 bar). Due to these relatively high pressures, traditional repair couplings are subject to a number of problems that prevent them from being used in refrigeration systems that use carbon dioxide. Limitation. One limitation is that a relatively high coolant pressure will be applied to the service valve and therefore an excessive torque will be required to turn the knob. Another limitation is that, due to being trapped between the service coupler and the filler connection before the connection is interrupted The pressurized refrigerant, repair coupling's "quick-connect feature" becomes practically inoperable. This clogging pressure can also cause the service coupling to undergo an undesired violent disconnection from the packing interface. Yet another limitation is that the flow rate of the cooling meter through a 200402518 traditional maintenance coupler during the evacuation of a refrigeration system is quite high. In a refrigeration system using carbon dioxide as a coolant, a rather high evacuation flow rate. Sb can cause gaseous coolant to trap in a seal. A high evacuation flow rate may also result in the filling interface. Or the dry ice in the connector ”, which may prevent the maintenance connector and the packing interface from being resealed and allow the coolant to escape. Therefore, the filling and venting are like those that use relatively high pressure of carbon dioxide. For refrigeration systems, an improved maintenance coupling is required. [Summary of the Invention]-A maintenance coupling system is provided with a coolant supply and a source connected to a refrigeration system having a packing interface, the packing interface includes a An axially displaceable interface valve. The maintenance coupler includes a main body portion having a central passage and a lateral interface, the central passage extending from a main shaft extending from an adjusting end to an outlet end And the lateral interface is positioned at the end providing communication between the central channel and the refrigerant supply source An axially movable valve housing system is disposed in the central channel. The valve housing system extends from a first end positioned between the lateral interface and the outlet end to a Positioned at a second end near the adjusted end. The valve housing includes at least one pressure equalizing passage extending therethrough from the first end to the second end, and an overhaul The valve train is sealingly engaged within the valve housing. An actuator system is provided for the valve housing to move from a rearward position toward the adjusting end to a forward position toward the outlet end Position. The axial movement of the valve housing to the forward position 200402518 causes the service valve to abut the port valve and disengage the port valve from the engagement relationship in the packing interface order to open a coolant. Flow path. The axial movement of the valve housing to the forward position will also create a space between the second end of the valve housing and the main body portion. This space is related to the flow of refrigerant Path by at least A passageway extending through the valve housing and in communication so that the pressure in the valve housing according to any of one end portion of substantially balancer. Substantially balanced in any of the one end portion of the valve housing pressure based only

The area of the P position 58 adjacent to the flange 194 preferably has an inwardly facing annular groove 198 ', and a retaining ring system is positioned in the annular groove. As shown in FIG. 1, the retaining ring is adjacent to the flange 194 and a shoulder 202 on the locking sleeve 184 to prevent the locking sleeve 20 200402518 from being removed from the main body portion 58. Alternatively, Or combined with the retaining ring portion 200, a second retaining ring portion 204 can be arranged in a groove 206 near the outlet end portion 62, and the role of the second retaining ring portion 204 is also to prevent The locking sleeve 184 is removed from the body portion 58. The maintenance coupling 20 is preferably provided with an interlocking sleeve 208 to prevent the maintenance coupling 20 from being inadvertently released from the packing connection 22 when the flow path of the coolant is opened. Referring to Figures 1 through 3, the interlocking sleeve 208 is a substantially cylindrical member having an inner diameter slightly larger than the outer diameter 212 of the main body portion 58. The interlocking sleeve 208 is provided with a channel 214 whose width is slightly larger than the diameter of the link structure 56. A first end 216 of the interlocking sleeve 208 is engaged with the locking sleeve 184 and a second end 218 of the interlocking sleeve 208 is engaged with the knob 70. Referring to FIG. 2, when the knob 70 has been turned to a position that causes the maintenance valve 118 and the interface valve 44 to open, the interlocking sleeve 208 abuts the locking sleeve 184 to prevent the locking sleeve 184 from being retracted. A position that will release the filler connection 22. On the other hand, as shown in FIG. 3, when the knob 70 is rotated to a position where the maintenance valve 118 and the interface valve 44 are closed, the interlocking sleeve 208 can be slid on the main body portion 58 to an allowable locking sleeve. 184 Release the position of the filler connection 22. In operation 'when the maintenance coupling 20 is disengaged from the packing interface 22', the locking sleeve 184 will be in its non-retracted or forward position as shown in FIG. 2 and is acted upon by the biasing of the elastic member 190 The example remains in this position. As shown in FIG. 3, the maintenance coupling 20 is a retracted locking sleeve 184 connected to the packing interface 22, which allows the pawl ball 1 8 when the maintenance coupling 20 is engaged with the packing 03/21 200402518 〇 Can move outward. When the maintenance coupler 20 engages the packing interface 22, the inlet end portion 28 of the packing interface 22 will enter the outlet end portion 62 of the maintenance coupler 20 and sealingly engage the sealing member 150. Further axial movement of the filler joint 22 toward the adjustment end 60 causes the pawl ball 180 to ride over a shoulder 22o located on the filler joint 22 until the pawl ball 18o radially contacts the One groove 222 in the packing connection 22 is consistent. The result of the locking sleeve 184 being pushed in response to pushing the elastic member 190 and the action of the conical cam surface 188 pushing the pawl ball 180 inward radially is that the pawl ball 180 is forced radially inward. Advance within. The pawl ball 180 is connected to one side of the shoulder 220 moved from the inlet end 28 of the filler interface to the farthest shoulder 220 to fix the maintenance coupling 20 to the filler interface 22 as shown in FIG. 1. 'When the maintenance coupling 20 is so engaged with the packing interface 22, it should be noted that no coolant will flow through the combined components. Therefore, within the packing connection 22, the sealing member 50 is hermetically connected to the core main body a 'and the maintenance valve 11 is hermetically engaged with the sealing member 116 within the maintenance coupling 20. ^ Before opening the inspection valve 118 and the interface valve 44, repair the coupler system 20! Pressurized by a maintenance hose or other conduit attached to the coolant supply / evacuation system. The dense member 144 on either side of the lateral connection π 66 prevents the coolant from passing between the main body portion 58 and the valve housing. Therefore, there is no pressurizing force acting on the valve housing 82 in the axial direction that would prevent the screw # 7 () from rotating to open the maintenance coupling 20. 22 200402518 In order to open the maintenance coupling 20 and the packing interface 22 for the flow of coolant through the lateral interface 66, the knob 70 is turned in a first predetermined direction, which causes the knob 70 to move axially to FIG. 2 Shown location. By the action of the valve housing 82 in contact with the sealing members 140 and 144, as a result of the frictional resistance to this rotation of the knob 70, such rotation does not cause the valve housing 82 to substantially rotate. The axial movement of the valve housing 82 from the position of Fig. I to the position of Fig. 2 causes the maintenance coupling 20 to directly engage the interface valve 44. Once the service valve 118 contacts the interface 阙 44, due to the pressure in the cooling system of the resistance interface valve 44, there will be some resistance against the further axial movement of the valves 118 and 44. However, since the diameter of the interface valve 44 is relatively small, this resistance is not usually significant. Referring to Fig. 2, when the valves 118 and 44 start to open, a first cavity 224 formed between the packing interface 22 and the valve housing 82 will be quickly filled with the added coolant. At the same time, the passage 96 allows a first cavity or space 266 formed between the valve housing 82 and the shoulder to achieve the same pressure. The substantially balanced pressure on either side of the valve housing 82 will only produce a minimum axial force acting on the knob 70 (generally combined with the biasing force of the compression valve spring). Therefore, all that is required for turning the knob 70 is a torque that can accept a large +.

When the valve body 82 is moved to the backward position toward the adjustment end 60 as shown in FIG. The valve housing 82 is disengaged, and the god force that is blocked in the first cavity 224 can escape through the force discharge path 232. Fig. 8 'An alternative embodiment of the present invention is not shown in detail. In this embodiment, the maintenance coupling 20 is provided with a rotatable nut 25 200402518 236 instead of a retractable locking sleeve 184 for fixing the maintenance coupling 20 to the packing interface 22. The nut a% is provided with an internally threaded surface 238 that engages an externally threaded surface 240 of the packing interface 22. The screw cap 236 also includes an indeterminate portion, which is connected to an inwardly directed groove 242 in the main body portion 58. The anchor: portion 24i allows the nut 236 to rotate relative to the main body portion 58: but it prevents axial movement thereon. In order to prevent accidental release of the filler joint π 22, the interlocking sleeve may be provided with __ internal rack surfaces, which are engaged with the nut 236 when the interlocking sleeve is moved forward due to the rotation of the screw 70 An external rack surface (not shown). With reference to Fig. 9, an alternative embodiment of the present invention is not shown in detail. In this embodiment, the maintenance coupling 20 does not include a thin interlocking sleeve to prevent accidental release of the packing connector 22. Instead ,: a bolt 244 that can be moved radially is provided at the main body M: Zheng Xian is radially centered 1 when the valve housing 82 is actuated toward the outlet end 62 to prevent the interlocking sleeve 184 Slide to an internal end portion 246 of the peg 244 that will release the filler connection lifted as shown in FIG. 9 and a head portion 248 with a chamfered corner. By using at least one ring seal member like ◦ between the pegs 240, the cut strips stick to the mountain to prevent the coolant from escaping.阙 The housing 82 is provided with an end portion 6Γ 252, which is the position of the joint portion when the valve housing 82 is moved to a forward position toward the outlet and the port 2 due to the inspection room ⑴ μ and the main body Γ. Open, whether alone or in combination with the pressure of the coolant present between the cymbal shell and the cymbal 58, these 26 200402518 engagements will cause the pegs 244 to move outward until one of the pegs 244 The part > ^ extends from the main body σP position 58. When the maintenance valve 118 and the interface valve 44 are open, the protruding portion of the 'check nail 244 will engage the interlocking sleeve 184 and prevent the interlocking sleeve member 184 from being accidentally retracted. Once the valve housing 82 is moved to a rearward position toward the adjustment end 60 and the service valve 118 and the interface valve 44 are closed, the interlocking sleeve 1 can be retracted so that the bolt M * is pushed into the main body 58 In. In yet another alternative embodiment of the present invention, a dual function maintenance coupling 20 'is disclosed in Figs. 10-14. In the above embodiment, the male filler interface 22 includes a pin 44 that pushes the peg. However, in some cases it may be necessary to incorporate a screw-type valve as described below. Moreover, in the embodiment discussed above: the valve assembly "is composed of a wide housing 82 that is moved axially by being directly connected to the knob 70. The valve housing The body contains a spring-loaded valve 118 with a dowel pin 228, which is pushed open by the main body of the male service interface and sequentially opens the male service interface valve. The difference in the embodiments discussed below lies in the "valve assembly, It consists of a series of shafts. The shafts are connected to the knobs, and a spring-loaded safety sleeve system is moved axially together with the shafts. The safety sleeve is opened when it touches the end of the male service interface 'and the valve of the male service interface is pushed away by the shaft. A more detailed description is as follows. The common actuator is this knob. A more detailed description of this embodiment is described below 'which includes a specific original number according to the included illustration. 27 200402518 The screw-type valve 302 includes the use of mating threads 303, 304 between an inner peripheral surface of the packing connection 22, and an outer peripheral surface of the valve to limit the valve to the packing connection. The threads 3 and 30 are passed in a first direction (for example, the direction of rotation of the left hand), and the threads related to the shaft are in the opposite direction (for example, the direction of rotation of the right hand) A series of restriction rings 3G5 are shown, which are used to prevent the valve 302 from accidentally disengaging from the packing connection 22 when the valve 302 continues to be unscrewed from the packing connection 22, one of the valves 302 The inner peripheral surface 3 06 and an outer peripheral surface located on a protruding ㈣ 356 ± of a shaft 350 are added as a matching hexagonal drive element, which can be "Allen", "τ〇Γχ" or other suitable designs . When the hexagonal drive element is connected, the non-circular male and female elements 306 and 307 allow the valve 302 to rotate relative to the packing interface 22 via threads 303 and 304 to make the valve 30 along the main axis A- A produces a longitudinal movement within the filler connection 22 '. Regardless of whether it is incorporated in the filler connection 22, either a push-type valve 44 or a screw-type valve 30 ° 27 coupling 20 'is designed to function in a selected equivalent manner. Therefore, the service technician does not need to know or worry about what type of packing interface valve is being added to the system. For the purpose of discussion, both types of valves are partially shown in the packing interface 22, but in practice, one or the other valve will usually be added to the packing interface. The component symbols introduced above are incorporated into the coupler 20 to the extent that they are practically practicable and have the same purpose except for the other aspects mentioned. 200402518 As can be seen most clearly from Fig. 10, Fig. 10A and Fig. 'Maintenance coupling 20' includes a main body portion 58 'which extends from an adjustment end portion 60 to an outlet σ end The portion 62 is also rigidly held in place. In the second place, the main body portion 58 includes two sections 108 and 110 ', where the section 110 is substantially the same as that discussed above. However, the segment 108 'has some ^^^^^. First, the section of the section 108, has a slightly "Γ" shape and has a gripped outer, longitudinally extending foot 308, which is defined by an inner surface defined by an inner diameter 76 and- Between the outer surfaces defined by an outer diameter 212. The leg 308 includes at least two circulation holes 94 extending therethrough between the inner and outer surfaces, the holes having the holes disposed therein. Radial recesses # 31〇 on each side and entering the inner surface, these radial grooves are suitable for receiving annular sealing elements A-B. Although shown in the figure are elastic O-rings , Especially for this kind of application, it may be necessary to use other types of seals (such as the ρτρΕ discussed above to provide spring-powered "U_cup") to eliminate explosive reductions. A light part 3i2 The connecting foot is connected with a shorter radial inner foot 314 / in. The P foot 3 14 ends at the end W longitudinally separated from the two grooves. The foot 308 and the inner foot Feet 314 are generally three-dimensional cylindrical, and the feet 314 are radially on the feet 308 Internally, the light portion 312 is disposed between the legs. Therefore, the two legs, 314 and 312 define a cavity 3 j 8. A drainage hole is attached at ^ The cross section shown in the figure passes through the pedestal at the abutment ㈣312 and terminates in the cavity 318. An elastic member like a spring is restricted 29 200402518 Within the cavity 318, it has a connecting spoke 312 The first end and a second end extending longitudinally outside the cavity. A safety sleeve 324 acting like a valve housing is arranged at the end 316 adjacent to the inner leg 314 and in the cavity The exterior of 318 is directly opposite the inner surface of the contact foot 308. A radial outer surface connects the sealing element A and Shi Rutai; ^ v queen sleeve g 324 is defined at a first end 328 and a first Between the two end portions 33 °, one or more discharge holes are said to extend longitudinally through a safety sleeve between the two end portions 328, 33 °.

When a push-pin type valve 44 is used, the first end 352 is engaged with the valve for opening and closing the valve, as will also be discussed in more detail below. The shaft 350 includes a protruding portion 356 adjacent to the first end portion 352 which really has an outer diameter, and has a transition region defined by an inclined chamfer Mg and a top portion 360 adjacent to the hexagonal element. The outer diameter of the top portion 360 is larger than the outer diameter of the protruding portion 356 and a flat portion extending longitudinally. A groove 362 is disposed at a sharply inclined angle adjacent to the transition area, and a substantially vertical shoulder 3 64 is adjacent to the delimiting wire? 31 200402518 from the top 360 of one of the walls of the groove. A sealing element d is configured to bear against the shoulder 364. Generally, the sealing element D is bonded to the shoulder 3 64. However, a groove type configuration may also be used. The respective diameters of the tops 334 and 360, as well as the transition areas of the safety sleeve 324 and the various longitudinal positions of the shaft 350 will result in the selective engagement of the sealing element D against the chamfer 340 as discussed in more detail below. The shaft 350 uses the threads 37, 372 to engage the legs 314 of the valve body section 108, which is adjacent to the spoke 312, in a threaded manner. These threads are

From the adjacent 3 = with a longitudinal extension that adjoins the flat portion of the inclined surface 382, VI and One shoulder with a shallower angle of 384 is that the W part is adjacent to the other one of the top 386 and one is vertical to one of the rear recesses. 90, ..., Ai, and the termination of the price order, the The rear groove 39o has a sharply inclined, substantially vertical wall portion 392 at 32 200402518 relative to the end of the groove. The shaft 35o may include the indicated elements directly without relying on the use of a shaft sleeve 378. The knob 70 includes a simple restriction ring groove 394, which is applicable = accommodation-a restriction ring 396, so that when the knob is moved longitudinally between a connected position and a disengaged position, the limiting ring is 3% As will be explained in more detail in the text ^ between groove 38o and rear groove 39o 1 In the embodiment shown, a shaft sleeve 378 is included to allow the T control limit ring to The magnitude of the moment may be elastic, but this may also be the needlessly. An internal radial surface 392 of the knob 70, includes two longitudinally configured grooves 393, which are suitable for restricting seal elements: ^ H . The sealing elements G and H are selectively engaged with the main body portion μ, the outer surface of the segment leg 308 and are partially defined by the diameter 212, to provide a fluid tightness when the discharge hole 1 320 is disposed therebetween. = Male, Feng. A longitudinal inner end 398 of the knob 70 'includes a selective chamfer 400 so that when the knob 70 is in its fully retracted orientation, the discharge hole 320 opens to the external environment. , Showing the dual-function maintenance coupling 20, in one of the following directions and rotation of the 70, the system is fully retracted. The sealing elements A to 0 are combined to function and can be used regardless of the position of the knob 70, to prevent leakage from the pressurized supply hose connection '. It is pressurized by a supply hose 450 attached to the maintenance equipment. The sealing element A # B on either side of the circulation hole 94 is sealed with the same diameter. 6.89 33 200402518 seals and prevents leakage and leakage between the safety sleeve 324 and the main body portion 58. The sealed 7G pieces C and D prevent leakage between the shaft 35 and the safety sleeve 324. This arrangement of seals results in the safety sleeve being substantially pressure-balanced, so that only the biasing force of the elastic member 322 will act to keep the safety sleeve in a closed position against the seal, where the piece D is sealed. This orientation system reduces the required square rotation force to the minimum by turning the knob 70. In the positions shown in Fig. 10 and Fig. 丨, the other four sealing elements E to D are not pressurized. In FIG. 10, the knob 70, is fully retracted and the restriction of the knob. The ring 396 is positioned in the rear groove 39 of the shaft sleeve 358, and the shaft sleeve is rigidly connected. To the shaft 35. The drive pin π * confined in the shaft 350 (and optionally through the entire shaft) is disengaged from the corresponding drive slot 376 in the knob 70 ,. Therefore, the knob 70 'can be rotated without restriction. When the knob 70 'is moved to the position shown in the figure after the repair, the discharge hole 320 is not covered, allowing any blocked pressure to escape. The sleeve 184 may be retracted ' to allow connection to the male stuffing port 22 ' or to interrupt the connection to the male stuffing port 22 ', as already discussed above. Figure 11 illustrates the function of the safety sleeve 324. In this illustration, the knob 70 'is advanced from its disengaged position, but the valve is still closed as shown in FIG. There is no packing connection 22, which is connected to the maintenance coupling 20 ,. The discharge hole 320 is closed and sealed between the sealing elements G and Η, where the sealing elements are accommodated in one of the grooves 393 on the peripheral surface of the knob 70, 34200402518. ten. The restraint ring 396 is arranged in the 刖 square groove 380 and the restraint pin is restrained within the driving slotted hole 3 76. However, no undesired pressure release occurred. This is because, as shown in the figure, when the safety sleeve is not fixed to the filler joint 22, regardless of the position of the knob 70 ,, the safety sleeve 324 is spring-loaded to a closed position by the spring 3: 2. And will always be kept in its closed position. In FIG. 12, the maintenance coupling 20 shown in the figure is connected to the lubricating filler joint 22. During this connection, if applicable, the hexagonal elements 306, 307 will be enlarged, so that the shaft 35. Rotating clockwise results in longitudinal movement of the valve 302 toward the end flange 328 of the safety sleeve 324. In the case of using the push-pin valve 44, the protruding portion 356 of the shaft 35 includes a cut angle 452, which is suitable for engaging the valve when the shaft 350 has been advanced far enough. The end M # of 44 is used to engage the valve 44 and the valve 44 moves to the left in the figure. In the illustration, the system produces insufficient longitudinal advancement to produce an interactive joint. The knob 70 'has been pushed forward longitudinally with minimal effort until the restriction ring 396 rests on the shallow inclined shoulder 388, leaves the groove 39o, the oval top 386, and enters the front groove 38o. During this action, the driving pin 374 will engage a driving slot 376 in the knob 70, so that any clockwise rotation of the knob will be between the shaft 350 and the main body 58 '. The cooperation of the threads 37 and 372 is coupled to rotate and advance the shaft 350. In addition, 'by pushing the knob 35 6 / i 200402518 button 70' forward, the discharge hole 320 will be sealed as discussed in relation to FIG. Figure 13 illustrates the maintenance coupling 20 'in the attached and open position. The interlocking sleeve 208 will function in conjunction with the locking sleeve 184 as already discussed above. Compared with Fig. 12, the knob 70
