Description

Technical Field

[0001] The utility model relates to the fields of railways and passenger transportation facilities, and particularly relates to an efficient water filling joint for passenger cars with an independent disconnection actuator. Background Art

[0002] At present, each carriage of high-speed EMU trains is equipped with a dedicated water injection port. The water filling process of the train is often completed manually. Generally, a water filling hose is used to connect the water injection port of the train to the water filling plug between the tracks, and the water filling plug is controlled to complete the water filling operation with the train. The connection between the hose and the train water injection nozzle is realized through a water filling joint provided at the front end of the hose. Before the water filling operation, the water filling worker needs to insert the water filling joint into the train water injection nozzle. After the water filling is completed, the water filling joint needs to be pulled out from the train water injection nozzle. Currently, both the insertion and extraction of the water filling joint need to be completed manually. During the water filling operation, a staff member usually needs to perform water filling operations on multiple carriages within the same time period, that is, needs to operate multiple water filling plugs simultaneously. Such accidents of forgetting to pull out the water injection pipe occur every year. Once forgotten to pull out, after the train starts, an accident of pulling the water injection pipe off will occur. Therefore, it is necessary to design a water filling joint that can automatically disconnect the water injection pipe.

[0003] Currently, the patent with the application number "201711064753.9" discloses a water filling joint device for passenger cars. In this technical solution, the friction between the rubber sleeve and the train water injection nozzle is used for clamping, and then the water pressure is used to make the two tightly connected and fixed. Even after the water injection stops, this friction will not disappear, that is, it will still be in a clamped state with the train water injection nozzle. Then, when gas is introduced, the gas is used to push the piston to drive the guide to move and push the train water injection nozzle, so as to overcome the friction between the rubber sleeve and the water injection nozzle. Therefore, during the process of separating the water injection nozzle, due to the continuous existence of the frictional clamping force, the air pressure required for removal is relatively large, there are unsafe factors, and even the above-mentioned joint may fly off.

[0004] Based on this, it is necessary to develop an efficient water filling joint for passenger cars with an independent disconnection actuator to overcome the above technical problems and achieve the purpose of smooth and safe separation. Summary of the Utility Model

[0029] Embodiment

[0030] As Figure 1 、 2 shown in Figures 3, 4, 5, the high-efficiency passenger car water supply joint with an independent shedding actuator in this embodiment includes an outer tube body 1, a rubber sleeve 2 and an inner top tube 3. One end of the outer tube body 1 is open, and the other end is sealed with a water supply hose connection body 4. The rubber sleeve 2 is installed inside one end of the outer tube body 1. The rubber sleeve 2 and the inner wall of the outer tube body 1 form a closed first chamber. One end of the rubber sleeve 2 close to the water supply hose connection body 4 is connected with a tubular sealing portion 411 extending towards the other end of the outer tube body 1. A tubular piston valve assembly 5 is slidably installed outside the sealing portion 411. A second chamber is formed between the piston valve assembly 5, the sealing portion 411 and the outer tube body 1. The inner top tube 3 passes through the piston valve assembly 5. One end of the inner top tube 3 is hermetically and slidably connected to the inner side of the sealing portion 411. The other end of the inner top tube 3 hermetically passes through the piston valve assembly 5. An elastic member 6 is connected between the other end of the inner top tube 3 and the piston valve assembly 5. A third chamber is formed between the inner top tube 3 and the piston valve assembly 5. A first inlet 31 is opened on the side wall of the other end of the inner top tube 3. A second inlet 32 is opened on the side wall of one end of the inner top tube 3. A piston member 34 in contact with the inner wall of the inner top tube 3 is provided between the first inlet 31 and the second inlet 32. The piston member 34 is connected with a top push pipe column (designated by f in the figure) extending towards one end of the inner top tube 3. An air inlet is provided in the water supply hose connection body 4, and the air inlet is respectively communicated with the first chamber and the second chamber.

[0031] Specifically as follows:

[0032] S11. First, ventilate through the air inlet. The air flow enters the first chamber and the second chamber respectively. The rubber sleeve 2 expands and tightly holds the train water injection nozzle. The air flow entering the second chamber pushes the piston valve assembly 5 to move. During the movement, the elastic member 6 is compressed, and the first inlet 31 is opened (as Figure 1 shown).

[0033] S12. Start water injection. After the water enters through the upper water hose connector 4, it enters from the other end of the inner top pipe 3, and then passes through the first inlet 31 - the third chamber - the second inlet 32 - the inner top pipe 3 - the train water injection nozzle for filling.

[0034] S13. After the water injection is completed, first disconnect the air path. The first chamber and the second chamber quickly deflate, and the rubber sleeve 2 no longer holds the train water injection nozzle tightly. At the same time, the elastic member 6 drives the piston valve assembly 5 to move back to its original position and close the first inlet 31 again (as shown in Figure 2 the figure).

[0035] S14. Next, the piston member 34 inside the inner top pipe 3 is pushed as a whole under the action of water pressure (as shown in Figure 3 the figure). Synchronously, the water pressure acts on the end of the inner top pipe 3, causing the inner top pipe 3 to drive the piston valve assembly 5 to move as a whole until the piston valve assembly 5 moves to the maximum stroke (as shown in Figure 4 the figure).

[0036] S15. The train water injection nozzle is "pushed" to be separated from the outer pipe body 1 (as shown in Figure 5 the figure).

[0037] During the whole process, first let the rubber sleeve 2 hold the train water injection nozzle tightly under the gas pressure, and introduce gas at this time. Use the gas to push the piston valve assembly 5 to open the first inlet 31 (that is, the water inlet), and the train starts to fill with water. After the water filling operation is completed, first turn off the air source power and quickly exhaust the air. The piston valve assembly 5 returns to its position and closes the first inlet 31. The water pressure quickly pushes the inner top pipe 3 out, and pushes the train water injection nozzle to realize the automatic separation of the water filling joint and the train water injection port, thus ensuring the safety of train water filling. Overall, there is no need for manual operation to unplug the joint. After the water injection is completed, it can fall off automatically, greatly improving the safety and eliminating the possibility of unsafe accidents caused by forgetting to unplug during the traditional operation process.

[0038] In this embodiment, an inner sleeve 13 is provided on the inner wall of the outer tube body 1. One end of the inner sleeve 13 is close to the outer wall of the inner sleeve 13, and an air groove penetrating through both ends thereof is provided. One end of the inner sleeve 13 is close to the positioning ring seat 112. One end of the sealing portion 411 is provided with an annular mounting portion (designated by e in the figure) fixedly connected to the inner wall of one end of the inner sleeve 13. The other end of the rubber sleeve 2 is clamped between the mounting portion and the positioning ring seat 112. One end of the piston valve assembly 5 is in sealed contact with the outside of the sealing portion 411 and the inner wall of the inner sleeve 13 respectively. The piston valve assembly 5 can slide relative to the sealing portion 411 and the inner sleeve 13. A third chamber is defined among the inner sleeve 13, the sealing portion 411 and the piston valve assembly 5. An overflow hole communicating the air groove and the third chamber is provided through the side wall of one end of the inner sleeve 13. A piston member 34 in contact with the inner wall of the inner top tube 3 is provided between the first inlet 31 and the second inlet 32. The piston member 34 is connected with a push tube column extending towards one end of the inner top tube 3. An air inlet is provided inside the other end of the outer tube body 1. An air hole penetrating through both ends thereof is provided in the positioning ring seat 112. One end of the air groove communicates with the air hole, and the other end communicates with the air inlet. In the whole embodiment, the air path part is arranged inside the outer tube body 1, and the overall design of the outer tube body 1 is relatively compact and beautiful. The diversion and delivery of the air path to the first chamber and the second chamber can be realized through the air groove and the overflow hole on the surface of the inner sleeve 13, and the structural design is relatively ingenious.

[0039] In this embodiment, an end cover is installed at the other end of the inner sleeve 13. An air inlet joint 15 is provided on the end cover. The end cover is provided with an overflow hole penetrating through both ends thereof. The port of the air inlet joint 15 extends into the water supply rubber tube connecting body 4 and forms the air inlet (designated by n in the figure, and this air inlet is connected to a trachea q). An air passage communicating the air inlet and one end of the air groove is provided inside the air inlet joint 15. The air inlet and the water supply rubber tube connecting body 4 are located at the same end of the outer tube body 1 and are concentrically distributed, that is, the external water pipe port is internally provided with an air path interface. When docking with the water pipe, after being inserted into each other, the conduction between the air path and the water path can be realized, and the connection of the pipe is relatively convenient.

[0040] In this embodiment, the piston valve assembly 5 includes a piston tube sleeve 55. One end of the piston tube sleeve 55 is hermetically sleeved outside the sealing portion 411, and the two can slide relative to each other. The piston tube sleeve 55 is in sealed contact with the outside of the sealing portion 411 and the inner wall of the inner sleeve 13 respectively. The other end of the piston tube sleeve 55 is provided with a joint portion 551 having a diameter smaller than it. The other end of the inner top tube 3 is hermetically penetrated through the joint portion 551 and is provided with an outwardly protruding limiting portion. An elastic member 6 is connected between the piston tube sleeve 55 and the limiting portion. The structural design of the piston valve assembly 5 is relatively simple. At the same time, the design of the narrowed joint portion 551 is conducive to the sealed sleeve fit between the inner top tube 3 and it.

[0041] In this embodiment, the above-mentioned water inlet hose connector 4 is threadedly connected to the other end of the outer tube body 1. Specifically, the water inlet hose connector 4 is a pipe shell-shaped component adapted to the outer tube body 1. One end of it is open, and the other end is provided with a water inlet, which is connected to the tap water pipeline. The inner wall of the open end of the water inlet hose connector 4 is provided with internal threads, and the outer wall of the other end of the outer tube body 1 is provided with external threads, and the two are threadedly connected, which is relatively convenient for disassembly and assembly. After the water inlet hose connector 4 is assembled, it will press the end cover, and the assembly between the osteotomies is relatively compact and stable.

[0042] In this embodiment, the above-mentioned elastic member 6 can adopt a conventional spring.

[0043] As a preferred embodiment, as Figure 6 shown, it further includes a control system. The above-mentioned control system includes a gas source P, an air inlet pipeline R, a first control valve S, a water supply pipeline T, and a second control valve U. The above-mentioned gas source is connected to the above-mentioned air inlet through the air inlet pipeline. The above-mentioned first control valve is arranged on the above-mentioned air inlet pipeline. One end of the above-mentioned water supply pipeline is connected to the tap water supply pipe, and the other end is connected to the above-mentioned water inlet hose connector 4. The above-mentioned second control valve is arranged on the above-mentioned water supply pipeline. The above-mentioned first control valve and the second electric control are respectively connected to the controller. A pressure gauge V and a filter W are arranged on the above-mentioned air inlet pipeline. The operation of this control system is as follows:

[0044] When the above-mentioned first control valve is opened, the gas source enters the first chamber and the second chamber. The gas entering the second chamber pushes the above-mentioned piston valve assembly 5 to move and compress the elastic member 6, and the above-mentioned first inlet 31 is opened. After that, when the above-mentioned second control valve is opened, the water source enters the train filling nozzle through the above-mentioned first inlet 31, the second chamber, and the second inlet 32 for filling. After the filling is completed, the above-mentioned first control valve is closed, the above-mentioned first chamber exhausts, and the elastic member 6 pushes the piston valve assembly 5 to move back to its original position, closing the above-mentioned first inlet 31. The inner push tube 3 moves towards one end of the above-mentioned outer tube body 1 under the action of water pressure, so as to push the entire water inlet joint out of the train filling nozzle.

[0045] In the above-mentioned implementation scheme, the on-off and flow state of the gas path and the water path in the whole pipeline can be controlled through the control system, that is, the operation of water inlet and terminal separation can be controlled.

[0046] In this embodiment, both the first control valve and the second control valve are electric control valves. It is convenient to control the flow state of the pipeline. Electronic control is very convenient.

[0047] In this embodiment, the first control valve and the second control valve are respectively connected to the controller. Through this controller, the operation can be automated and intelligentized, reducing the burden of manual operation.
