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 type of valve such that the user is not required to know which type of valve is present.

The service coupling can also be used to drain the coolant from a cold well system. 7 ”/ [Previous Technology] Traditional coolants such as fluorocarbons (CFCs) and fluorocarbons (HCFCs) are tightly controlled because they consume ozone in the atmosphere. They are used to replace Current exploration of new and environmentally friendly coolants for CFCs and HCFCs is directed towards the use of hydrofluorocarbons (HFCs) such as R134a. However, compared to natural coolants such as carbon dioxide or Armenia, HFCs still show a fairly high global temperature rise (GWP) and higher cost of use. These stakes have stimulated research needs for alternative refrigeration systems that use coolants other than HFCs. The use of carbon dioxide as cooling With the development of refrigerant refrigeration systems, the industry of automatic air conditioning has begun to address the challenge of replacing HFCs. It is used to supply coolant from a coolant through an inlet in the cooling system or a "charging" interface. The source leads to 1230235-a repair coupler or adapter for a refrigeration system that is well known to those skilled in the art ... a known repair coupler Utilization - :: be "quick-connect" to the cold; Characteristics of the East filler interface systems. Once connected, a maintenance valve in the maintenance connector will be connected to 1 and actuate a connection in the filler interface to open the connection between the continuous filler interface and the coupler. Between a cooling valve, a maintenance valve, and a maintenance valve, it is generally a rotatable knob that moves into the connection relationship between the person and the interface. In the basin, the green 4 is connected to the connector. . d. Money can be connected in a thread-like manner such as those used in the R134a automatic "system. The system-type maintenance couplings are usually designed to work at up to about _PSi (6.9 bar). However, ' The hoisting system of the refrigeration system using carbon dioxide as a coolant is significantly higher than that of the R134a cold rolling system, which means that it is higher than 100 psi (6.9 bar). The two phases § Pressure, traditional maintenance couplers will be subject to several restrictions in the east system that prevent them from being used for CO2 cooling.-The high cooling force of the material limit phase will be applied to the maintenance room, so An excessive amount of torque will be required to turn the knob. Magic 7-item is limited to 'Due to the pressurized refrigerant trapped between the real connector of the maintenance connector before the connection is interrupted, the "quick connection feature" of the maintenance connector becomes practical. Unable to operate. This clogging pressure can also cause the 4 service connection 11 to occur-an undesired violent disconnection from the filler interface. Yet another limitation is that the flow rate of the cooling meter through a 23023 conventional maintenance connection during the evacuation of a refrigeration system is relatively high. In a refrigeration system using carbon dioxide as the coolant, a rather high evacuation flow rate can cause the gaseous coolant to trap in a seal. A rather high flow rate may also cause "dry ice" to form in the packing interface or the repair coupling, which may prevent the repair coupling and the packing connection from resealing and allow coolant to escape. Therefore, for fillers and evacuation systems, such as those using a relatively high pressure of carbon dioxide, a maintenance coupler is required. [Summary] A maintenance coupler system is used to disperse a coolant. The supply source is connected to a cold; East system with a packing interface, the packing interface includes an interface valve that can be axially displaced. The maintenance coupling includes a main body with a central channel and a lateral interface Location, the central channel extends along a major axis from an adjusted end to an exit end, and the lateral interface is positioned to provide a space between the central channel cough and cold supplement supply Between the communicating ends. A valve housing system that can be moved axially is arranged in the central channel. The valve housing system is positioned on the side from one A first end portion between the interface and the outlet end portion extends to a second end portion positioned close to the adjusting end portion. The valve housing includes at least one passage therethrough from the first end portion. An end portion extends to a pressure equalizing channel at the second end portion, and a service valve system is sealingly engaged within the valve housing ... an actuator system is provided for the valve housing from one direction The rearward position of the adjusting end is moved to a forward position toward the outlet end. The axial movement of the valve housing to the forward position of the guide 1230235 / nuclear 6 valve is closely related to the interface valve and from Disengage the interface valve in the coupling relationship in the packing interface to open a coolant flow path. Axial movement of the valve housing to the forward position will also produce a second between the valve body A space between the end portion and the main body portion. The space is a passage through which the coolant flows through at least one passage extending through the valve housing, and communicates with one another on either end of the valve housing. The pressure is roughly balanced. The pressure that is generally balanced on the part is only generated by a minimum amount of force, which is required to move the valve housing in the central channel. In the example, the maintenance coupler is provided with at least one outflow passage for discharging the added coolant between the sinking coupler and the packing interface before the connection is interrupted. The valve housing reaches the forward position. The motion system of the flute seals the outflow path, and the motion of the valve housing in the rearward position closes the flow path and allows it to sink into the maintenance coupling. Residual coolant can be released through the unsealed outflow channel. In yet another example of the present invention, the lateral interface system is lifted to connect the maintenance coupling to a The coolant supply / discharge system is a joint structure. Xi 5. # ^ μ ,,,, ° The component includes a non-return valve or is limited by the direction finding interface and limits the coolant flow in one direction Generally speaking, the first part of the wife's heart is relative to the first direction. Wen the direction of coolant flow through the lateral limits of the interface. In another embodiment having a month, the packing interface may include a valve of the type or a valve of the screw type. The main body of the valve is-12 1230235 $ The shaft has extra functionality and the valve housing contains a safety sleeve, which is combined with the main body of the valve which is rigidly positioned. The service coupling will function in a manner that is equivalent to any valve in operation. … The other advantage is that the innovative Lai Lai design of the creative maintenance coupler allows a coolant flow path to be opened with minimal effort: The packing of a relatively high pressure system is connected to the maintenance Coupler between. Another advantage is that the coolant trapped between the packing connection σ and the maintenance coupling is closed after the maintenance coupling and the interface valve are closed: allowing the maintenance coupling to be easily and relatively The ground was disconnected from the filler in a less sighing manner. Yet another advantage is that the flow rate of the coolant evacuated from the refrigeration system can be immediately controlled by a check valve to minimize the occurrence of explosive decompression or dry ice formation. For those skilled in the art, when studying in accordance with the accompanying diagram: Temple, the other various concepts and advantages of the present invention will become clear from the detailed description of the following preferred embodiments.

At 22 disengagements, 'the locking sleeve f 184 will be in its non-retracted or forward position as shown in FIG. 2' and is held in this position by the biasing action of the elastic structure 190. As shown in FIG. 3, the repair coupling 20 is retracted with the locking sleeve 184 to be connected to the filler joint π 22 ', which allows the pawl ball 180 to be outward when the repair coupling 2q is engaged with the filler 21 1230235 bushing. mobile. "When the Tian, Yang couplers 20 are connected to the filler joint 22, the ^ 4 28 of the filler joint 22 will enter the exit end 62 of the maintenance coupler 20 and sealably engage the seal member i 50. The filler joint 22 faces the adjustment The progressive axial movement of the end 60 causes the pawl ball 80 to sit on one of the shoulders 22 on the padding interface 22 until the pawl ball is radially in contact with the padding interface 22 One groove is consistent. The result of pushing the sleeve # 184 as a result of the reaction pushing the elastic member 19G and the cone 幵 v cam surface 1 88 pushes the pawl ball 1 8 in a controlled manner inwardly φ the pawl ball The object 180 is pushed radially inward with force. The pawl ball 180 is connected to one side of the shoulder 220 which is moved from the inlet end 28 of the filler interface to the furthest distance to connect the maintenance. The device 20 is fixed to the packing interface 22. As shown in FIG. 1, when the maintenance coupling 20 is so connected to the packing interface 22, it should be noted that no coolant will flow through the combined components. Therefore, at the packing interface 22 Within, the sealing member 50 is hermetically sealed from the core , 42 are connected, and the maintenance coupler 8 series is sealedly connected with the sealing member 116 within the maintenance coupler 20. Before the maintenance valve 1 and the opening valve 44 are opened, the maintenance coupler 20 series passes through Maintenance hoses or other conduits attached to the coolant supply / evacuation system are pressurized. Sealing members 144 on either side of the lateral interface 66 prevent the coolant from attaching to the main body 58 Passes through the valve housing 82. For this reason, there will be no pressurizing force that will prevent the coupling 20 from rotating in the axial direction to act on the valve housing 82. 22 1230235 Maintenance couple, 纟士 7 n 、, and quot; and the filler interface 22 are opened for the movement of the coolant through the lateral interface 66. The knob 70 is turned on in the first-order :: Rotating, which causes Xuanzhi 70 to move axially to = shown by @ 2. By the action of the valve housing 82 in contact with the sealing member 14G * i44, as a result of the frictional resistance of the rotation of the material 7G, the government type does not cause the valve housing 82 to perform a solid f rotation. The axial movement of the valve housing 2 from the position of Fig. 1 to the position of Fig. 2 causes the maintenance coupling 20 to directly engage the interface valve 44.

However, this resistance is usually not significant due to the diameter phase J of the interface valve material. 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 is quickly filled with a pressurized coolant. At the same time, the passage 96 allows a second cavity or space 266 formed between the valve housing 82 and the shoulder 06 to reach the same pressure.

The minimum axial force on the Ugly 70 (usually combined with the offset force of the compression valve elastic yellow). Therefore, all that is required for turning the knob 70 is an acceptable amount of torque. Full rotation of the knob 70 in this first predetermined direction will cause the service valve 118 and the interface valve 44 to be actuated to be fully retracted or "opened," positions, allowing the coolant to flow completely. According to the resistance service valve 11 8 and interface valve 44 acting offset force 23 1230235 'It is possible that the service valve 118 will not be actuated to the fully "open" position. To ensure that the service valve 118 is fully actuated, a dark The dowel pin 228 extends through the maintenance valve 118 and extends out of the valve housing 82. During the insertion of the filler joint 22 into the maintenance coupling 20, the inlet end 22 of the filler joint 22 will be concealed. The dowels 228 and actuate the service valve 118 to the fully "opened" position shown in FIG. In order to disconnect the maintenance coupling 20 from the packing connection 22, it is only necessary to turn the knob 70 to close the valves 118 and 44 and manually retract the locking sleeve m to the position shown in FIG. This retraction moves the shoulder 188 of the locking sleeve m out of the ridge with the pawl ball 180 and thus aligns the pawl ball 180 with the enlarged cylindrical wall 182, allowing the pawl ball The 18G may move radially outward to disengage the shoulder 220 of the filler interface 22. However, it is difficult to implement (if not impossible) to retract the locking sleeve I 184 manually if it is blocked in the first cavity: the pressure of the tincture. The blocked coolant will exert an axial force on the filler interface 22, and this force will be re-introduced into the locking sleeve 184 via the pawl ball 18o. The pressure in it is discharged.

A light portion 312 connects the foot 308 with a shorter radial inner foot 314 '. The inner foot 3 14 ends at an end 316 longitudinally separated from the two grooves. The legs 308 and the internal legs 314 are substantially three-dimensional cylindrical 'and the legs 3 14 are radially inside the legs 3 0 8, and the jurisdiction 3 12 is disposed between the legs. Therefore, the two legs 3 0 8 and 3 14 and the spoke portion 312 define a cavity 318. A discharge hole 32o passes through the foot 308 at the adjacent spoke 312 in the cross section shown in the figure, and terminates in the cavity 318. An elastic member 322 like a spring is restrained. 29 1230235 Within the cavity 318 it has a first end that engages the spokes 312 and a second end that extends longitudinally outside the cavity. A safety sleeve 324 acting like a valve housing is disposed adjacent the end 316 of the inner leg 314 and faces the inner surface of the contact leg 308 outside the cavity 318. A radial outer surface 326 connects the sealing element A and the safety sleeve 324 is defined between a first end portion 328 and a second end portion 33. One or more discharge holes 332 extend longitudinally through Pass the safety sleeve between the two ends 328, 33. The second end portion 330 is selectively in contact with the end portion 316 of the inner leg 314 of the main body portion and is continuously in contact with the spring 322, and is described in the following. It is directed toward a closed position and toward the filler. Interface 22 'is skewed. The safety sleeve 324 also includes one or more flow-through holes 334 which extend from the exterior surface and terminate at an internal radial surface φ. The circulation hole ... does not intersect the discharge hole 332. The safety sleeve 324 has a thin projection 338 adjacent the end 328. A transition area including an inclined cut-off angle 340 and a crest with a longitudinally extending flat portion is arranged between the protruding portion and the circulation center. Preferably, the top 342 sentences of the ancient Jrn, a "dagger" has an inner diameter smaller than the inner radial surface 336. When the end post of the safety sleeve 324 is also + the magic foot 330 and the inner leg 314 of the main body part When the end 316 of the contact is in contact with each other, the selective intersection between the chamfered angle 34 and the top 342 and the sealing element, and ° 0 restrict the backward travel of one shaft 350 The radial inner surface of the safety sleeve 324 adjoining the second end 支 330 and the inner leg 314 adjacent 30 1230235 and then 邛 3 16 includes a recess suitable for restricting the sealing elements 1000 C and F. Slot 343. WA ^ ^ 7 and F series are partially arranged at any intersection between the safety sleeve 324 and the inner _, 0i L ^ and foot 314 set of 339 Lu Heng feet to seal except for discharge The cavity outside the hole 332 prevents the fluid from flowing into the cavity. The external characteristics and maintenance coupler components are described in another step below. The force at this position is combined with the advance θ — a longitudinal direction. The extension 35G system acts like a maintenance valve ι 但 8, but = the shaft also includes another function. The passageway seems to be accommodated radially and inwardly in an internal passage defined by Rong Jinju and 隹 by the queen sleeve 324. A shaft 350 extends from a sacral armor to a first end 352 and an Between the second end portion 4. The hexagonal element π is arranged on an outer side of the shaft 350 adjacent to the first end 352, and is suitable for a hexagonal element corresponding to the thread-valve 302. 306 cooperates to open and close the filler interface 22 when the filler interface includes this type of time, as discussed in more detail below. When using a push pin type g 44, the-end The portion 352 is connected to the valve for opening and closing the room, as will be discussed in more detail below. The shaft 350 includes a protruding portion 56 adjacent to the first end portion 352 having an outer diameter. There is a transition area bounded by a slanted chamfered state and the top of an adjacent hexagonal element. The outer diameter of the top 360 is greater than the outer diameter of the protrusions and a longitudinally extending flat portion.-_ 362 is a Severe tilt angle is matched Adjacent to the transition region, the substantially vertical shoulder 364 abuts the top 36 of one of the walls of the groove 31 1230235 $. — Dense == shoulder 364. Generally speaking, the sealing element D would end up X "P 364. However, a groove type configuration may also be used. Each of the relevant diameters of the top 334 and 360 and the safety sleeve-like passages and: the longitudinal position of the rod will produce a more selective joint of 70 seals D against the chamfer 340 as described in more detail. Shaft :: 2 uses threads 370, 372 to engage the legs 314 of the valve body section 1G8, which are adjacent to the spoke Γ through the threads, where these threads are connected to the threads 303, 304 and # 4 · m_ 3 304 relative, used to allow the longitudinal movement of the shaft relative to the valve body ^. As can be seen most clearly from FIG. 10B, one or more drive pins 374 extending outwardly and spaced apart are arranged between the thread 37 and the end 354 of the shaft, and such The "driving stud" 4 series is arranged within the matching hole of the shaft 350. The driving stud m is suitable for engaging the driving slotted hole W which is dislocated in a rotatable knob 7Q. One is not quilted It is nailed otherwise, the rod sleeve claw system fixed to the shaft 35 is positioned between the driving bolt 374 and the shaft end 3M and stands out ^, and the shaft sleeve 378 includes- With a play ... roughly the front groove 38 of the vertical front square wall portion 382, and the obliquely inclined bevel surface which is formed behind the front groove ^ ^-with- A longitudinally extending top 386 adjoining the flat portion of the bevel 382, and a shoulder having a shallower angle than the bevel 384, the shoulder is adjacent to the other longitudinal end of the orchid 386 and the line ends at Among the rear recesses 90, the rear recess 39 has a sharply inclined, 32 1230235 phase J at the end of the recess, Induced wall portion perpendicular to use. The 350 can include indicated components directly without having to rely on the use of a shaft sleeve 3 7 8. Fang Yuan Niu 70 'includes a simple limit sword ^ M Gen J-Jack groove 394, which is suitable for ordering a restriction ring 396, so that when the knob is fixed at a joint position: When moving longitudinally between the positions, the circumfluence system is restricted to move between the recess 380 and the rear recess as described in detail below. The embodiment includes a shaft sleeve 378. So that the magnitude of the moment of the control control limit ring can be a ^ ^ ^ M has elasticity, but this may also be considered as important. An inner radial surface 392 of the knob 70 'includes two longitudinally arranged grooves 393, which are suitable for restricting the sealing element. The sealing element 〇 and Η are selectively engaged with the main body part 58, which is the outer surface of the foot fan and is partially defined by the diameter 212. The Tian 32G is provided with a fluid spin ... a longitudinal inner end 398 includes a selectable chamfer 400 such that when the knob 70 is in its fully retracted orientation, the exhaust hole 320 will open to the external environment. The dual-function maintenance coupling 2q is shown in the broken heading direction and turns red 70, and the system is fully retracted. The sealing element A works together to prevent leakage from the pressurized supply port # 总仏应车人官连接 66 # wherever the position of the button 70 ′ can be prevented. After the maintenance device 20 'is attached to the packing interface, the difference between $ a ^ ^ 丄 * and the maintenance coupling 20 will usually be attached to the supply hose 45 of the maintenance equipment and any of the holes 94 will be added. From the side of λ t, you can seal 70 pieces of A and B through the hole of the machine and seal the same diameter 33 1230235 and prevent leakage between the safety sleeve 324 and the main part 58. Sealing element C and D prevent leakage between the shaft 35 and the safety sleeve 324. The arrangement of this seal causes the safety sleeve U4 to be approximately a pressure balancer, so that only the biasing force of the elastic member 322 will It acts to keep the safety sleeve in a closed position and is sealed against the sealing element D. This orientation system reduces the required rotational force by turning the knob 70, to a minimum. In the position shown, the other four sealing elements E to Η are not pressurized. In Figure 10, the knob 70, is fully retracted and the restriction ring 396 of the knob is positioned at In the rear groove 39 of the shaft sleeve 358, and the shaft sleeve is Rigidly connected to the shaft 35. The drive pin M * 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 maintenance, the discharge hole 320 is not covered, allowing any blocked pressure to Escape. The sleeve 184 can be retracted to allow connection to the male packing connection 22 'or to interrupt the connection to the male packing interface 22, as already discussed above. Figure 11 reveals the safety sleeve Function of 324. In this illustration, the knob 70 is advanced from its disengaged position, but the valve is still closed as shown in Fig. 10. There is no filler port 22, and it 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 a groove 393 on the peripheral surface of the rotating red 70, one of 34 1230235 The restriction ring 396 is arranged in the J square groove 3 80 and the restriction bolt system is limited to the driving slotted hole 376. However, no undesired pressure release has occurred. This is because as shown in the figure, regardless of the position of the knob 70, when the safety sleeve When the 324 is not fixed to the packing interface 22, the safety sleeve 324 is spring loaded to a closed position by a spring and will always be maintained in its closed position. The authentic interface 22 in the mulch. During this connection, the hexagonal '7C pieces 306 307 will be enlarged if applicable, so that the clockwise rotation of the shaft 35 () will cause the valve 302 to move longitudinally toward the end 328 of the safety sleeve 324. In the case of using the push-pin valve 44, the protrusion of the shaft 35o: the 356 series includes a cut angle 452 'This cut angle 452 is suitable for the shaft, the 35o has been advanced far enough The end of the hour engagement valve 44 is used to engage the valve 44 and the valve 44 moves to the left in the figure. In the illustration, the '' produced an insufficient longitudinal advancement, which resulted in an interactive joint. Xuanhong 7〇 'has been pushed forward longitudinally with minimal effort. The restriction ring 396 rests on the shallow inclined shoulders, leaves the groove carrying the ® shaped top 386 and enters the front groove. In doing this: the moving stud 374 will engage a drive shaft 35 in the knob 70. : The clockwise rotation of the main will rotate and advance due to the cooperation of the coupling rod 350 of the threads 37G and 372. In addition, by pushing forward the screw 35 1230235 11 is sealed as discussed 70. The exit hole 320 will be as shown in the figure.
