Description

Technical Field

[0001] The utility model relates to the field of supercharger fluid replenishing devices, in particular to a fluid replenishing device for a supercharger formed by filling a liquid into a vehicle structural pipe. Background Art

[0002] The refill device for the supercharger used in the liquid-filled molding of automotive structural pipe fittings rapidly replenishes liquid within the supercharger, which provides the high internal pressure during the molding process. During the supercharger refill process, the refill device is required to have a short refill time (controlled within 15 seconds) and a stable refill flow rate. However, the overflow valve of the refill pump in existing refill devices is easily damaged, resulting in unstable refill pressure and flow rate, increasing refill time and affecting production efficiency. Furthermore, if the refill device's one-way valve reverses during the high-pressure process on the supercharger, leaking (i.e., liquid backflow), it will cause serious damage to the refill pump and pipeline. Utility Model Content

[0003] In order to overcome the problems in the above-mentioned background technology that the overflow valve of the existing fluid replenishing device is prone to unstable fluid replenishing pressure and fluid replenishing flow, which increases the fluid replenishing time and affects production efficiency, and the backflow of liquid in the one-way valve during the high-pressure process will cause serious damage to the fluid replenishing pump and pipeline, the utility model provides a fluid replenishing device for a vehicle structural pipe filling and forming supercharger. By arranging a tubular overflow valve and a solenoid valve on the connecting pipeline, the fluid replenishing pressure and fluid replenishing flow can be better stabilized, and the problem of serious damage to the fluid replenishing pump and pipeline when the one-way valve has liquid backflow can be avoided. It has the beneficial effects of being able to quickly and stably replenish fluid to the supercharger, improving production efficiency, and increasing the safety of the fluid replenishing device.

[0004] The technical solution of the utility model is as follows:

[0005] A fluid replenishment device for a liquid-filled supercharger for a vehicle structural pipe fitting includes a fluid replenishment pump and a one-way valve arranged on a connecting pipeline. A relief valve is installed at the liquid outlet end of the fluid replenishment pump. The fluid replenishment pump is arranged on the connecting pipeline at the liquid inlet position, and the one-way valve is arranged on the connecting pipeline connected to the supercharger. A tubular relief valve and a solenoid valve are arranged on the connecting pipeline between the fluid replenishment pump and the supercharger, and the tubular relief valve is arranged between the solenoid valve and the fluid replenishment pump.

[0006] Compared with the existing technology, the beneficial effects of this technical solution are:

[0007] (1) When the refill pump is working, the solenoid valve is closed, the liquid channel in the solenoid valve is closed, and the liquid will not pass through the solenoid valve and flow directly to the booster. When the booster is fully replenished, the solenoid valve is disconnected before the booster works, and the liquid channel in the solenoid valve is opened. If there is leakage due to the reverse cutoff of the one-way valve during the high-pressure process on the booster, the high-pressure leaked liquid will be discharged from the solenoid valve. Therefore, by setting the solenoid valve, the refill pump, the overflow valve and the connecting pipeline will not be damaged by the high-pressure impact, thereby reducing system failures. In addition, whether there is leakage in the one-way valve and the amount of leakage can be observed at any time, which is convenient for early prevention.

[0008] (2) By setting a tubular overflow valve between the solenoid valve and the rehydration pump and using it in conjunction with the overflow valve of the rehydration pump, the dual effect enables the rehydration pressure and rehydration flow rate to be more stable, avoiding the problem in the background technology that the rehydration pressure and flow rate are unstable after the overflow valve of the rehydration pump is damaged, which increases the rehydration time and affects the production efficiency. It has the effect of ensuring the rapidity and stability of the rehydration pressure and flow rate, and achieving the effect of rapid and stable rehydration;

[0009] (3) The rehydration time of this rehydration device can be stabilized within 13 seconds, shortening the rehydration time and reducing the system failure rate by 2 / 3. At the same time, the production cycle is increased by 1 / 3 and the production efficiency is increased by 1 / 3.

[0010] Preferably, the solenoid valve is a two-position four-way solenoid valve.

[0011] Preferably, a plurality of one-way valves are provided, and are respectively arranged on connecting branches of the connecting pipelines that are in one-to-one communication with the superchargers.

[0012] Further preferably, two one-way valves are provided, which are respectively arranged on two connecting branches of the connecting pipeline, and the output ends of the two connecting branches are correspondingly connected to the liquid inlets of the two superchargers.

[0021] Reference numerals: fluid infusion pump 1 , overflow valve 11 , one-way valve 2 , connecting pipeline 3 , connecting branch 31 , middle connecting pipeline 32 , liquid inlet 33 , booster 4 , tubular overflow valve 5 , solenoid valve 6 , switch valve 7 . DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Example 1: Figure 1 The illustrated fluid replenishment device for a supercharger in a vehicle structural pipe fitting includes a fluid replenishment pump 1 and a one-way valve 2 disposed on a connecting pipe 3. The fluid replenishment pump 1 is disposed on the connecting pipe 3 at the location of the liquid inlet 33 and is in communication with the liquid inlet 33. Liquid entering the connecting pipe 3 from the liquid inlet 33 is transported along the connecting pipe 3 to the supercharger 4 under the action of the fluid replenishment pump 1. The fluid replenishment device can replenish the supercharger 4 with liquid through the connecting pipe 3 under the action of the fluid replenishment pump 1. The fluid outlet of the fluid replenishment pump 1 is equipped with a built-in overflow valve 11 for regulating and balancing the liquid flow in the connecting pipe 3. The one-way valve 2 is disposed on the connecting pipe 3 connected to the supercharger 4 and is in communication with the supercharger 4 to control the flow direction of the liquid and prevent reverse flow of the liquid in the connecting pipe 3.

[0024] A tubular relief valve 5 and a solenoid valve 6 are arranged between the rehydration pump 1 and the booster 4. The tubular relief valve 5 is arranged between the solenoid valve 6 and the rehydration pump 1 and is respectively fixed to the central connecting pipeline 3 (i.e., the central connecting pipeline 32) via threaded connections. The tubular relief valve 5 typically includes a valve body, a valve core, a spring, etc. The valve body has one or more channels inside for guiding the flow of hydraulic oil. The valve core is kept closed by the spring until the hydraulic oil pressure exceeds a set value, at which point the valve core opens, allowing the hydraulic oil to overflow. Compared to the relief valve 11 provided at the outlet of the rehydration pump 1, the tubular relief valve 5 is more durable and has greater pressure resistance. The solenoid valve 6 is a two-position, four-way solenoid valve 6. The two-position, four-way solenoid valve 6 includes an electromagnet, a valve core, and a spring. The valve core is moved by the operation of the electromagnet. Its working principle is to control the movement of the valve core by energizing and de-energizing the electromagnet, thereby achieving the flow of liquid and switching its direction.

[0025] When using this fluid replenishment device, first set the working time of the fluid replenishment pump 1 according to the actual situation of different boosters 4. When the fluid replenishment pump 1 is working, the liquid enters the connecting pipe 3 from the liquid inlet 33 under the action of the fluid replenishment pump 1 and passes through the fluid replenishment pump 1 and the tubular overflow valve 5 in turn to reach the one-way valve 2 and enter the booster 4. After the fluid replenishment is completed, the fluid replenishment pump 1 stops working and the booster 4 is high-pressure. When the fluid replenishing pump 1 is working, the solenoid valve 6 is closed, the liquid channel in the solenoid valve 6 is closed, and the liquid will not pass through the solenoid valve 6 and flow directly to the booster 4; when the booster 4 is fully replenished, the solenoid valve 6 is disconnected before the booster 4 works, and the liquid channel in the solenoid valve 6 is opened. If there is a leakage due to the reverse cutoff of the one-way valve 2 during the high-pressure process on the booster 4 (that is, the liquid flows back), the high-pressure leaked liquid will be discharged from the solenoid valve 6, ensuring that the fluid replenishing pump 1, the relief valve 11 and the connecting pipeline 3 will not be damaged by the high-pressure impact, thereby reducing system failures. In addition, whether there is a leakage in the one-way valve 2 and the amount of leakage can be observed at any time, which is convenient for early prevention. A tubular overflow valve 5 is arranged between the solenoid valve 6 and the rehydration pump 1, and is used in conjunction with the overflow valve 11 provided by the rehydration pump 1. The dual effect enables the rehydration pressure and rehydration flow to be more stabilized, avoiding the problem in the background technology that the rehydration pressure and flow are unstable after the overflow valve 11 provided by the rehydration pump 1 is damaged, which increases the rehydration time and affects the production efficiency. The device has the effect of ensuring the rapidity and stability of the rehydration pressure and flow, and achieving the effect of rapid and stable rehydration. In addition, the rehydration time of the present rehydration device can be stabilized within 13 seconds, shortening the rehydration time, and reducing the system failure rate by 2 / 3. At the same time, the production rhythm is increased by 1 / 3, and the production efficiency is increased by 1 / 3.

[0026] Example 2: Based on Example 1, the one-way valve 2 is optimally designed. There are multiple one-way valves 2, and they are respectively arranged on the connecting branches 31 of the connecting pipeline 3 that are connected to the supercharger 4 in a one-to-one manner. That is, the present fluid replenishing device can replenish liquid for multiple superchargers 4 at the same time. Therefore, the outlet end of the middle connecting pipeline 32 (that is, the connecting pipeline 3 located in the middle) is dispersed into multiple connecting branches 31, and each connecting branch 31 is arranged with a one-way valve 2, which can control the flow direction of the liquid in each connecting branch 31, disperse the pressure to prevent liquid backflow, and improve the service life of a single one-way valve 2.

[0027] Preferably, two one-way valves 2 are provided, which are respectively arranged on the two connecting branches 31 of the connecting pipeline 3. The output ends of the two connecting branches 31 are correspondingly connected to the liquid inlets of the two boosters 4, and can provide liquid to the two boosters 4 at the same time, avoiding that when there are too many connecting branches 31, the middle connecting pipeline 32 is prone to bursting due to excessive pressure or cannot meet the liquid replenishment time requirements of each booster 4.

[0028] Example 3: Based on Example 1, the infusion pump 1 is optimally designed. There are multiple infusion pumps 1, and they are respectively arranged on the connecting branches 31 at the output ends of the connecting pipeline 3 at the liquid inlet 33 position. The output ends of the connecting branches 31 are uniformly connected to the connecting pipeline 3 located in the middle, that is, the present infusion device is provided with multiple infusion pumps 1 to provide a power source for the booster 4 to transport liquid. Therefore, the output end of the connecting pipeline 3 connected to the liquid inlet 33 position is dispersed into multiple connecting branches 31, and each connecting branch 31 is arranged with a infusion pump 1. The liquid passes through the infusion pumps 1 in different connecting branches 31, and then is uniformly collected in the middle connecting pipeline 32 and transported to the booster 4, thereby increasing the total transport power and dispersing the transport pressure of a single infusion pump 1.

[0029] Furthermore, there are two fluid infusion pumps 1, which are respectively arranged on the two connecting branches 31 of the connecting pipeline 3. The output ends of the two connecting branches 31 are communicated with the tubular overflow valve 5, that is, the outlet ends of the connecting branches 31 of the fluid infusion pumps 1 are uniformly collected into the middle connecting pipeline 32 and communicated with the tubular overflow valve 5. When problems occur in the overflow valves 11 of any one or two fluid infusion pumps 1, the tubular overflow valve 5 can stabilize the fluid infusion pressure and fluid infusion flow in time, thereby maintaining stable liquid delivery. If too many fluid infusion pumps 1 are set, the working pressure of the tubular overflow valve 5 will undoubtedly increase, affecting the effect of the action.

[0030] Example 4: Based on Example 1, a preferred design is implemented, with the connecting pipe 3 being a high-pressure hose. A high-pressure hose is a flexible pipe capable of withstanding high pressures, exhibiting high-pressure resistance and capable of withstanding pressures up to 25 MPa. Preferably, the central connecting pipe 3 (i.e., the central connecting pipe 32) is constructed of steel pipe. Each branch pipe 31 converges into the central connecting pipe 32, which is subject to greater pressure, and steel pipes have a stronger pressure-bearing capacity.

[0031] Example 5: Based on Example 1, a preferred design for the rehydration pump 1 is employed. This pump utilizes a plunger pump. This pump achieves oil suction and pressure by reciprocating a plunger within a cylinder, causing the volume of a sealed working chamber to change. This pump offers advantages such as high rated pressure, compact structure, high efficiency, and easy flow rate regulation.

[0032] Example 6: Based on Example 1, a preferred design is performed, in which a switch valve 7 is provided on the connecting pipeline 3 at the position of the liquid inlet 33. The switch valve 7 serves as a main switch to control the overall circulation and disconnection of the liquid in the connecting pipeline 3.

[0033] The above embodiments merely represent specific implementation methods of the present application. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the technical concept of the present application, and these modifications and improvements are all within the scope of protection of the present application.
