It should be understood, however, that the drawings and detailed description thereto are not intended to limit the disclosure to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims. The figures are for illustration and are not drawn to scale.
The existing X-ray or X-ray ball equipment needs to be filled with oil for cooling, and the filling mode is to vacuumize a cavity where the equipment is located or vacuumize an oil way of the equipment and then fill the oil. However, such a method is complicated to operate, is inconvenient to observe the injection process, and cannot circulate oil after the oil is injected, so that the insulativity of the oil cannot be detected, and pollutants and the like in the oil cannot be cleaned;
as shown in fig. 1, embodiments of the present disclosure provide an oiling apparatus 100 for a radiographic apparatus 200, comprising: an oil tank 50 defining an internal space 51, the internal space 51 of the oil tank 50 accommodating therein an insulating oil 52 for injection into the radiographic apparatus 200 and the insulating oil 52 filling a lower portion of the internal space 51 of the oil tank 50; a return line 20 comprising a return valve 21 configured to switch the return line 20 on or off, and a return end 101, wherein one end of the return line 20 is in fluid communication with an upper portion of the internal space 51 of said tank 50 to allow fluid to flow from the return end 101 of the return line 20 through the return line 20 into the internal space 51 of said tank 50; a filling line 30 comprising a filling valve 31 configured to switch the filling line 30 on or off, and a filling end 102, wherein the filling line 30 is in fluid communication with a lower portion of the inner space 51 of the tank 50 to allow the insulating oil 52 of the lower portion of the inner space 51 of the tank 50 to be discharged through the filling end 102 of the filling line 30. In the present embodiment, the return end 101 of the return line 20 is used for fluidly communicating with the first port 201 of the radiation apparatus 200, so that the fluid in the radiation apparatus 200 flows to the oil tank 50; the injection end 102 of the injection line 30 is adapted to be in fluid communication with the second port 202 of the radiographic apparatus 200 for injecting the insulating oil 52 into the radiographic apparatus 200 through the second port 202 of the radiographic apparatus 200. The tank 50 can thus form a fluid circuit with the radiation system 200 via the return line 20 and the filling line 30.
When the oil injection device 100 of the present embodiment is used for injecting oil into the radiographic apparatus 200, the return end 101 and the injection end 102 of the oil injection device 100 need only be respectively in fluid communication with two ports of the radiographic apparatus 200, and the oil tank 50 can form a fluid circuit with the radiographic apparatus 200 through the return line 20 and the injection line 30, so that the insulating oil 52 in the oil tank 50 flows into the radiographic apparatus 200, and the insulating oil 52 is injected, and simultaneously air, even residual oil, water and the like in the radiographic apparatus 200 can be discharged, and the operation is simple. The return line 20 in this embodiment can discharge not only air but also liquid and even the injected insulating oil 52 in the radiation apparatus 200 inside the radiation apparatus 200.
In one embodiment, the fill line 30 may further include a first one-way valve 32 therein, allowing fluid flow from the tank 50 to the fill end 102 of the fill line 30 while preventing reverse fluid flow.
In one embodiment, the injection line 30 further comprises an oil pick-up-and-fill 34 disposed in the injection line 30 downstream of the first one-way valve 32 in the fluid flow direction, the oil pick-up-and-fill 34 being configured to be able to suck the insulating oil 52 in the oil tank 50 and to be able to expel the insulating oil 52 towards the downstream injection end 102. The oil suction-injection device 34 sucks the insulating oil 52 from the oil tank 50, the insulating oil 52 can flow out of the oil tank 50 through the first check valve 32 and into the oil suction-injection device 34, and when the oil suction-injection device 34 discharges the insulating oil 52, the first check valve 32 prevents the insulating oil 52 from flowing to the oil tank 50, so that the insulating oil 52 discharged by the oil suction-injection device 34 only flows to the ray equipment 200.
In one embodiment of the present disclosure, as shown in FIG. 1, the oil suction-oiler 34 includes a sleeve 341; a piston 342 accommodated in the sleeve 341 in contact with an inner wall of the sleeve 341 and capable of reciprocating in the sleeve 341, a space where one surface of the piston 342 is sealed from the inner wall of the sleeve 341 for accommodating sucked insulating oil; and a bellows 343, one end of the bellows 343 being connected to the inner wall of the sleeve 341, and the other end of the bellows 343 being connected to the other surface of the piston 342 opposite to the one surface, so that a sealing connection is formed between the inner wall of the sleeve 341, the piston 342, and the bellows 343 to define a sealed space. In the present embodiment, when the injection valve 31 is opened, the piston 342 is moved rightward in the illustrated structure to draw the insulating oil 52 in the oil tank 50, and then the piston 342 is moved leftward to inject the insulating oil 52 into the radiographic apparatus 200 illustrated in the figure, and during this oil discharge, the first check valve 32 prevents the insulating oil 52 from flowing toward the oil tank 50. The piston 342 is moved to and fro (left and right direction) a plurality of times, and the insulating oil 52 is continuously sucked from the oil tank 50 and injected into the radiation apparatus 200. The oil pick-up-oiler 34 can have various embodiments. For example, one type of the oil suction-filler 34 may be a combination of the sleeve 341 and the piston 342, and the bellows 343 of the oil suction-filler 34 of the above-described embodiment is replaced with a seal. In some embodiments, the oil pick-up-oiler 34 may be an electrically powered device.
In one embodiment, the filling line 30 further comprises a second one-way valve 33, located downstream of said suction-filler 34 in the direction of fluid flow, allowing fluid to flow from the tank 50 to the filling end 102 of the filling line 30 while preventing reverse fluid flow. The provision of the second check valve 33 allows the oil suction-filler 34 to suck the insulating oil 52 in the oil tank 50 without sucking the gas or oil in the radiation device 200 into the oil suction-filler 34. It should be noted that in the case where the return valve 21 is turned off (the oil circulation valve is also turned off), the suction-injection pump 34 can suck the insulating oil 52 in the oil tank 50 without providing the second check valve 33.
In one embodiment, as shown in fig. 1, the oil injection device 100 may further include an oil circulation line 90 including an oil circulation valve 91 for controlling on-off of the oil circulation line 90, wherein one end of the oil circulation line 90 is connected to the oil tank 50, the other end is connected to the return line 20, and the oil circulation line 90 is connected to the return line 20 at a position between the return valve 21 and the return end 101 of the return line 20. In the present embodiment, the oil injecting apparatus 100 is configured such that the insulating oil 52 forms a fluid circuit between the oil tank 50 and the radiographic apparatus 200 in a state where the return valve 21 is off and the oil circulation valve 91 and the injection valve 31 are on. For example, when the oil suction/injection device 34 continuously sucks the insulating oil 52 from the oil tank 50 to inject the insulating oil 52 into the radiographic apparatus 200, the insulating oil 52 is returned to the oil tank 50 through the oil circulation line 90 after filling the radiographic apparatus 200, and the insulating oil 52 circulates in the oil tank 50-injection line 30-radiographic apparatus 200-oil circulation line 90-oil tank 50 fluid circuit. This is advantageous in that the circulation of the insulating oil 52 can carry away impurities, water or other substances in the radiation device 200. It should be appreciated that in other embodiments, the return line 20 may implement a fluid circuit of the tank 50-the injection line 30-the radiation device 200-the return line 20-the tank 50, and the insulating oil 52 may circulate therein, without providing the oil circulation line 90.
In one embodiment of the present disclosure, as shown in fig. 2, the oiling device 100 may include: a return line 20, an injection line 30 and an evacuation line 10, the evacuation line 10 being in fluid communication with an upper part of the inner space 51 of said tank 50. The evacuation line 10 includes: a vacuum unit 12 for pumping gas from an upper portion of the inner space 51 of the oil tank 50, and an air pumping valve 11 for controlling on-off of the vacuum pumping line 10. In one embodiment, the oiling device 100 may comprise an evacuation line 10, a return line 20 and an injection line 30, the oiling device 100 being configured to evacuate gas from the upper part of the inner space 51 of the tank 50 through the evacuation line 10, such that the insulating oil 52 flows from the tank 50 to the evacuated radiographic device 200 with the return valve 21 and the injection valve 31 being switched on.
In another embodiment, the oiling device 100 may include an evacuation line 10, a return line 20, an injection line 30, and an air line 40, the air line 40 being configured to fluidly communicate the outside air with the upper portion of the inner space 51 of the oil tank 50, and including an air valve 41 to control on-off of the air line 40; the oiling device 100 is configured such that gas in the upper portion of the internal space 51 of the oil tank 50 and gas in the inside of the radiographic device 200 are pumped through the evacuation line 10 with the injection valve 31 and the gas delivery valve 41 disconnected, and then the insulating oil 52 is caused to flow from the oil tank 50 to the radiographic device 200 by negative pressure by controlling the opening degree of the gas delivery valve 41 in the gas delivery line 40 with the suction valve 11 and the return valve 21 disconnected and the injection valve 31 connected.
In one embodiment of the present disclosure, the oil injection apparatus 100 includes the above-described vacuum pumping line 10, the return line 20, the injection line 30, and the air line 40, wherein the injection line 30 further includes the above-described first check valve 32, the oil suction-injection device 34, and the second check valve 33. In the present embodiment, the oil injection device 100 is configured to control the opening degree of the gas delivery valve 41 in the gas delivery pipe 40 to allow the insulating oil 52 to be injected from the oil tank 50 into the radiographic apparatus 200 under the action of the negative pressure, after the gas in the upper portion of the internal space 51 of the oil tank 50 and the gas in the radiographic apparatus 200 are extracted using the evacuation line 10, and then, in the case where the evacuation valve 11 and the return valve 21 are turned off and the injection valve 31 is turned on; the oil suction-injection device 34 may be used to suck the insulating oil 52 in the oil tank 50 and inject the insulating oil 52 into the radiation device 200.
In an embodiment of the present disclosure, the oil injection device 100 includes the above-mentioned vacuum pumping pipeline 10, the return pipeline 20, the injection pipeline 30, the gas pipeline 40, and the oil circulation pipeline 90 includes an oil circulation valve 91 for controlling on-off of the oil circulation pipeline 90, wherein the oil circulation pipeline 90 connects the oil tank 50 with the return pipeline 20, and the position where the oil circulation pipeline 90 is connected with the return pipeline 20 is between the return valve 21 and the return end 101 of the return pipeline 20. In the present embodiment, the injection line 30 further includes the first check valve 32, the suction-oiling device 34, and the second check valve 33, which have been described above. The oiling device 100 is configured such that the insulating oil 52 forms a fluid circuit between the oil tank 50 and the radiographic device 200 in a state where the return valve 21 is off and the oil circulation valve 91 and the injection valve 31 are on after the insulating oil 52 fills the radiographic device 200. Under the action of the suction-filling unit 34, the insulating oil 52 continuously flows from the oil tank 50 into the radiographic apparatus 200 and then flows back from the radiographic apparatus 200 into the oil tank 50. Since air has been drawn through the vacuum drawing line 10, in the case of a small vacuum degree, the gas in the insulating oil 52 escapes from the insulating oil 52, and particularly, when the insulating oil 52 containing gas returned from the radiographic apparatus 200 is mixed into the insulating oil 52 in the oil tank 50, the gas in the insulating oil 52 in the oil tank 50 escapes from the insulating oil 52 to reenter the insulating oil 52 in the radiographic apparatus 200 without containing gas, and the gas in the radiographic apparatus 200 is removed.
In an embodiment of the present disclosure, the oil tank 50 may be located higher than the radiation device 200, so that the insulating oil 52 in the oil tank 50 may automatically flow to the radiation device 200 under the gravity (the injection valve 31 is turned on). The oil tank 50 may be at the same level as the radiographic apparatus 200, however, when the level of the insulating oil 52 in the oil tank 50 is higher than the radiographic apparatus 200, the insulating oil 52 may autonomously flow from the oil tank 50 to the radiographic apparatus 200, thus greatly simplifying the structure of the oiling apparatus 100. In the embodiment where the oil suction-filler 34 is provided, the position of the oil tank 50 is not required, and the insulating oil 52 can be sucked from the oil tank 50 by the action of the oil suction-filler 34 and then injected into the radiation device 200. The oil pick-up-and-oil injector 34 may improve the efficiency of the oil injection into the radiographic apparatus 200 and may facilitate the removal of impurities such as gas or water from the radiographic apparatus 200.
Fig. 3 shows an embodiment of the present disclosure, and as shown in the drawing, the oiling device 100 may further include a heater 63 for heating the insulating oil 52 of the lower portion of the inner space 51 of the oil tank 50, and a temperature controller 62 for measuring the temperature of the insulating oil 52 to control the heating of the heater 63 so that the insulating oil 52 is at a desired temperature. For example, the temperature controller 62 may include a sensor 61 disposed in the insulating oil 52 for measuring the temperature of the insulating oil 52. For example, the insulating oil 52 is controlled to be around 60 degrees. This is advantageous in that when the insulating oil 52 is heated, water and gas in the insulating oil 52 are removed at an accelerated speed, and the insulating oil 52 is purified, so that the insulating oil 52 injected into the radiation device 200 is free of gas and moisture. In practical applications, which is particularly advantageous, the insulating oil 52 can be degassed or water-removed quickly, so that the insulating oil 52 injected into the radiation device 200 is free of water and gas; also, since the oiling device 100 itself can remove water and gas, the utilization efficiency of the insulating oil 52 can be improved, so that the water-and/or gas-containing insulating oil 52 returned from the ray device 200 can be reused without a separate device for removing water and gas.
