Description

A straight-through one-way valve and liquid cooling system

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 17, 2023, with application number 202311052546.7 and invention name “A straight-through one-way valve and liquid cooling system”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present invention relates to the technical field of connectors, and more particularly to a straight-through one-way valve. Furthermore, the present invention also relates to a liquid cooling system comprising the straight-through one-way valve. Background Art

[0003] In related technologies, in energy storage systems, energy storage batteries generate a lot of heat during the charging and discharging process, so they need to be cooled. Currently, liquid cooling systems are generally used to cool energy storage batteries. The entire liquid cooling system includes a water generator, a water replenishment system, and a cooling water circulation system. The water generator is a hot and cold water exchange system that cools the hot water returning from the battery end and then supplies cold water to the cooling water circulation system to cool the battery. The water replenishment system is used to replenish water pressure in the water circulation system when it is insufficient.

[0004] Typically, a one-way valve is installed between the water supply system and the cooling water circulation system to automatically replenish the cooling water in the cooling water circulation system. When the water pressure in the cooling water circulation system is too low, the one-way valve will automatically open after the water supply system pressure exceeds a certain pressure value in the cooling water circulation system, and perform the relevant fluid replenishment operations. When the water pressure in the cooling water circulation system returns to normal, the one-way valve closes, isolating the water supply system from the cooling water circulation system.

[0005] In the process of implementing the present invention, the inventors discovered that the prior art has at least the following problems:

[0006] In existing one-way valves, one end of the valve stem is slidably connected to the valve body, and the other end is slidably connected to the valve cover. If there is a coaxial discrepancy between the valve stem and the valve body, or between the valve stem and the valve cover, the valve stem can easily become stuck during movement, which can easily cause the elastic return member mounted on the outer periphery of the valve stem to fail, resulting in uneven sliding and, in turn, preventing the one-way valve from opening and closing properly. Furthermore, a valve stem installed in the direction of valve opening can easily cause impurities to accumulate, becoming lodged in the gap between the valve stem and the guide hole in the valve cover, which can also cause the valve stem shaft to become stuck during movement, further causing the elastic return member to fail, resulting in uneven sliding and preventing the one-way valve from opening and closing properly.

[0007] In summary, how to solve the problem of the one-way valve being unable to open and close normally due to the coaxiality difference between the valve stem and the valve cover or the deposition of impurities is an urgent problem to be solved by those skilled in the art.

[0008] Summary of the Invention

[0018] a base portion, the base portion dividing the valve body into the valve core cavity and the connecting cavity, and the base portion is provided with the first through hole;

[0020] Wherein: one end of the valve stem is movably arranged on the guide part, and one end of the elastic reset member is fixed in the guide part.

[0021] In one possible design, a first cavity is provided in the valve stem, and a second cavity is provided in the guide portion;

[0022] Wherein: one end of the elastic return member is fixedly arranged in the first cavity, and the other end is fixedly arranged in the second cavity.

[0023] In a possible design, one end of the guide portion is inserted into the first cavity, or one end of the valve stem is inserted into the second cavity, so that the valve stem can move along the guide portion.

[0024] In a possible design, the outer circumference of one end of the guide portion inserted into the first cavity is in contact with the inner circumference of the first cavity;

[0025] Alternatively, the outer circumferential surface of one end of the valve stem inserted into the second cavity is in contact with the inner circumferential surface of the second cavity.

[0026] In a possible design, a second through hole is further provided on the base portion, and the second through hole is used to connect the connecting cavity and the second cavity.

[0027] In a possible design, a sealing ring is sleeved on one end of the valve stem disposed in the valve core cavity;

[0028] A steel ring is provided inside the valve cover, and the steel ring is used to cooperate with the sealing ring to seal the flow channel;

[0029] Wherein: the sealing ring is provided with a PTFE coating.

[0030] In one possible design, the valve body is provided with a first thread on one end having the valve core cavity, and the valve cover is provided with a second thread on one end for connecting with the valve body. The valve body and the valve cover are detachably connected through the first thread and the second thread.

[0031] In a possible design, the guide seat and the valve body are an integrally formed structure.

[0032] A liquid cooling system comprises the straight-through one-way valve described in any one of the above items.

[0033] Compared with the prior art, the straight-through one-way valve and liquid cooling system provided by the present invention have at least the following advantages:

[0034] The straight-through one-way valve provided by the present invention includes a valve body, a valve cover, a valve stem, and an elastic return member. A guide seat is provided in the valve body, and the guide seat divides the valve body into a valve core cavity and a connecting cavity.

When the straight-through one-way valve is in a closed state, under the action of the elastic return member, the valve stem abuts against the valve cover to close the flow channel.

[0035] In a liquid cooling system using the straight-through one-way valve provided by the present invention, when the straight-through one-way valve is in an open state, the elastic return member is in a compressed state, the valve stem and the valve cover are separated, and the liquid in the liquid replenishment system of the liquid cooling system can enter the valve core cavity along the flow channel and then enter the connecting cavity through the first through hole; when the straight-through one-way valve is in a closed state, the elastic return member is in a released state, the valve stem and the valve cover abut against each other, closing the flow channel, thereby blocking the liquid flow between the liquid replenishment system and the straight-through one-way valve; since there is no matching relationship between the valve stem and the valve cover, the movement of the valve stem will not be affected by the coaxiality difference between the valve stem and the valve cover, and impurities in the liquid can flow normally along the flow channel, and the impurities are less likely to get stuck between the valve stem and the valve cover, so that the valve stem is less likely to get stuck during movement, and thus the one-way valve is less likely to be unable to open and close normally due to the valve stem getting stuck.

[0036] In summary, the straight-through one-way valve provided by the present invention can improve the problem of the one-way valve being unable to open and close normally due to coaxiality differences or impurity deposition.

[0037] In addition, since the liquid cooling system provided by the present invention includes the straight-through one-way valve, it can achieve the same technical effect as the straight-through one-way valve. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] The core of the present invention is to provide a straight-through one-way valve that can improve the problem of the one-way valve not being able to open and close properly due to coaxiality differences or impurity deposition. In addition, another core of the present invention is to provide a liquid cooling system including the straight-through one-way valve.

[0044] Please refer to Figures 1 and 2, wherein Figure 1 is a structural schematic diagram of the straight-through one-way valve provided by the present invention when it is in a closed state; Figure 2 is a structural schematic diagram of the straight-through one-way valve provided by the present invention when it is in an open state.

[0045] This specific embodiment provides a straight-through one-way valve, which can be used in a liquid cooling system. The straight-through one-way valve includes:

[0046] The valve body 1 has a guide seat 11 therein, which divides the valve body 1 into a valve core chamber 12 and a connecting chamber 13. The guide seat 11 has a first through hole 14, which is used to connect the valve core chamber 12 and the connecting chamber 13.

[0047] The valve cover 6 is detachably connected to one end of the valve body 1 where the valve core cavity 12 is located, and a flow channel is provided through the valve cover 6;

[0048] The valve stem 3 has one end movably disposed on the guide seat 11 and the other end movably disposed in the valve core cavity 12;

[0049] An elastic return member 2, one end of which is fixed in the guide seat 11, and the other end of which is fixed in the valve stem 3;

[0050] When the straight-through one-way valve is in the closed state, the valve stem 3 abuts against the valve cover 6 under the action of the elastic reset member 2, closing the flow channel;

[0051] When the straight-through one-way valve is in the open state, the elastic return member is in a compressed state, and the valve stem and the valve cover are separated, so the external liquid can flow into the valve core cavity 12 through the flow channel of the valve cover 6, and then flow into the target object through the first through hole 14 and the connecting cavity 13. It can be understood that when the straight-through one-way valve is applied between the water supply system and the cooling water circulation system of the liquid cooling system, that is, the two ends of the straight-through one-way valve are respectively connected to the water supply system and the cooling water circulation system of the liquid cooling system (the valve cover 3 is connected to the water supply system, and the valve body 1 is connected to the cooling water circulation system), when the straight-through one-way valve is in a closed state, the water supply system and the cooling water circulation system are separated by the straight-through one-way valve. At this time, the liquid in the water supply system will not flow into the cooling water circulation system; when the straight-through one-way valve is in an open state, that is, when the water pressure of the cooling water circulation system is too low, the liquid in the water supply system can flow into the cooling water circulation system through the straight-through one-way valve, so that the cooling water circulation system restores normal water pressure. After the cooling water circulation system restores normal water pressure, the straight-through one-way valve automatically closes to separate the water supply system and the cooling water circulation system.

[0052] It should be noted that in this embodiment, the elastic return member 2 can be a spring. Of course, in other embodiments, the elastic return member 2 can also be configured as other elastic structures. The guide seat 11 separates the valve core chamber 12 and the connecting chamber 13 in the valve body 1. The guide seat 11 is provided with a first through hole 14, which is used to connect the valve core chamber 12 and the connecting chamber 13, thereby allowing liquid to flow from the valve core chamber 12 to the connecting chamber 13. The valve cover 6 is provided with a through flow channel, and the valve cover 6 is detachably connected to the valve body 1. For example, the valve cover 6 and the valve body 1 are threaded.

[0053] It should also be noted that a sealing ring 4 can be sleeved on one end of the valve stem 3 located in the valve core cavity 12. Since one end of the valve stem 3 is movably provided on the guide seat 11, and the other end is movably provided in the valve core cavity 12, one end of the elastic return member 2 is fixed in the guide seat 11, and the other end of the elastic return member 2 is fixed in the valve stem 3. Therefore, the elastic return member 2 can provide an elastic force between the guide seat 11 and the valve stem 3. When the straight-through one-way valve is not connected to the water supply system and the cooling water circulation system of the liquid cooling system, under the action of the elastic return member 2, the valve stem 3 and the valve cover 6 can cooperate to close the flow channel of the valve cover 6, and the sealing ring 4 sleeved on the valve stem 3 can cooperate with the valve cover 6 to seal the flow channel of the valve cover 6.

[0054] During actual use, the shape, structure, size, material, position, etc. of the valve body 1, elastic return member 2, valve stem 3, sealing ring 4 and valve cover 6 can be determined according to actual conditions and actual needs.

[0055] When using the straight-through one-way valve provided by the present invention, when the water pressure of the cooling water circulation system of the liquid cooling system is normal, the straight-through one-way valve is in a closed state, and the structure is shown in Figure 1. The internal pressure of the cooling water circulation system of the liquid cooling system is always in a high-pressure state. This pressure and the elastic reset member 2 act on the valve stem 3 at the same time to support the valve stem 3, and the sealing ring 4 assembled on the valve stem 3 is in close contact with the valve cover 6 under the action of the lifting force, thereby playing a sealing role to avoid liquid leakage.

[0056] After the cooling water circulation system of the liquid cooling system has been running for a period of time, the residual gas in the system is discharged by the system exhaust valve, causing the system pressure to drop; or due to the partial poor sealing of the system, the liquid in the system will slowly overflow. After a period of time, the liquid in the system will decrease and the pressure will also drop; when the pressure drops to a certain level, it will exceed the rated force provided by the elastic reset member, that is, the pressure of the liquid replenishment system in the direction of the valve cover 6 exceeds the sum of the pressure (water pressure) of the cooling water circulation system and the pressure of the elastic reset member 2. At this time, the liquid replenishment system changes to a high-pressure area and the cooling water circulation system changes to a low-pressure area. This high pressure will push the valve stem 3 to open the straight-through one-way valve, and the seal between the sealing ring 4 and the valve cover 6 will be released. The liquid in the liquid replenishment system will be replenished into the cooling water circulation system until the pressure in the cooling water circulation system and the sum of the elastic force of the elastic reset member 2 reach equilibrium with the pressure of the liquid replenishment system. At this time, the sealing relationship between the sealing ring 4 and the valve cover 6 is re-formed, that is, the straight-through one-way valve returns to a closed state.

[0057] Among them, when the straight-through one-way valve is in the open state, the structure is shown in Figure 2. At this time, the elastic return two parts are in a compressed state, the valve stem 3 is separated from the valve cover 6, and the liquid in the liquid replenishment system of the liquid cooling system can enter the valve core cavity 12 along the flow channel, and then enter the connecting cavity 13 through the first through hole 14; when the straight-through one-way valve is in the closed state, the elastic return part 2 is in a released state, the valve stem 3 abuts against the valve cover 6, and the flow channel is closed, thereby blocking the liquid flow between the liquid replenishment system and the straight-through one-way valve; since there is no matching relationship between the valve stem 3 and the valve cover 6, the movement of the valve stem 3 will not be affected by the coaxiality difference between the valve stem 3 and the valve cover 6, and impurities in the liquid can flow normally along the flow channel, and impurities are less likely to get stuck between the valve stem 3 and the valve cover 6, so that the valve stem 3 is less likely to get stuck during movement, and then the one-way valve is less likely to be unable to open and close normally due to the jamming of the valve stem 3.

[0058] In summary, the straight-through one-way valve provided by the present invention can improve the problem of the one-way valve being unable to open and close normally due to coaxiality differences or impurity deposition.

[0059] In this embodiment, the guide seat 11 includes:

[0060] A base portion 15 , which divides the valve body 1 into a valve core chamber 12 and a connecting chamber 13 , and is provided with a first through hole 14 ;

[0061] A guide portion 16, one end of which is connected to the base portion 15 and the other end of which is located in the valve core cavity 12;

[0062] One end of the valve stem 3 is movably disposed on the guide portion 16 , and one end of the elastic return member 2 is fixedly disposed in the guide portion 16 , as shown in FIG1 .

[0063] A first cavity 7 is provided in the valve stem 3, and a second cavity 8 is provided in the guide portion 16;

[0064] One end of the elastic return member 2 is fixed in the first cavity 7 , and the other end is fixed in the second cavity 8 , to ensure that the elastic return member 2 does not separate from the guide portion 16 during use and can apply force to the valve stem 3 .

[0065] In this embodiment, one end of the guide portion 16 is inserted into the first cavity 7, allowing the valve stem 3 to move along the guide portion 16. Of course, in other embodiments, one end of the valve stem 3 may be inserted into the second cavity 8, allowing the valve stem 3 to move along the guide portion 16. This arrangement allows the guide portion 16 to accurately guide the movement of the valve stem 3, making the straight-through one-way valve less prone to malfunction.

[0066] The outer circumference of the end of the guide portion 16 inserted into the first cavity 7 is in contact with the inner circumference of the first cavity 7; or the outer circumference of the end of the valve stem 3 inserted into the second cavity 8 is in contact with the inner circumference of the second cavity 8. This arrangement of the guide portion 16 and the valve stem 3 helps maintain structural stability, prevents the valve stem 3 from swinging, and makes the movement of the valve stem 3 smoother, making the straight-through one-way valve less prone to failure.

[0067] In this embodiment, a second through hole 17 is further provided on the base portion 15 . The second through hole 17 is used to connect the connecting cavity 13 and the second cavity 8 .

[0068] It should be noted that the provision of the second through hole 17 on the base portion 15 facilitates assembly of the valve stem 3 and the guide seat 11. During assembly, air between the valve stem 3 and the guide seat 11 can be discharged outward through the second through hole 17, thereby reducing assembly difficulty. Furthermore, the second through hole 17 can also discharge liquid from the first cavity 7 and the second cavity 8, thereby preventing prolonged accumulation of liquid in the first cavity 7 and the second cavity 8.

[0069] In this embodiment, a sealing ring 4 is sleeved on one end of the valve stem 3 arranged in the valve core cavity 12, and the sealing ring 4 is provided with a PTFE coating; a steel ring 61 is provided in the valve cover 6, and the steel ring 61 is used to cooperate with the sealing ring 4 to seal the flow channel.

[0070] It should be noted that the sealing ring 4 mounted on the valve stem 3, under the action of a lifting force (the combined force of the pressure differential and the elastic return member 2), can closely contact the valve cover 6, thereby sealing the flow path. The PTFE coating, commonly known as a non-stick coating, effectively prevents impurities in the liquid from adhering, thereby forming a more reliable seal between the sealing ring 4 and the valve cover 6. Furthermore, when the sealing ring 4 on the valve stem 3 tightly abuts the steel ring 61 of the valve cover 6, the sealing ring 4 and the steel ring 61 work together to ensure that the flow path of the valve cover 6 is fully sealed, effectively sealing the one-way valve.

[0071] In this embodiment, the valve body 1 is provided with a first thread on one end having a valve core cavity 12, and the valve cover 6 is provided with a second thread on one end for connecting with the valve body 1. The valve body 1 and the valve cover 6 are detachably connected through the first thread and the second thread.

[0072] For example, an internal thread can be provided in the valve core cavity 12 of the valve body 1, and correspondingly, an external thread can be provided on the end of the valve cover 6 for connection to the valve body 1, so that the valve body 1 and the valve cover 6 are detachably threadedly connected via the internal and external threads. It is understandable that an external thread can also be provided on the end of the valve body 1 for connection to the valve cover 6, and an internal thread can be provided on the end of the valve cover 6 for connection to the valve body 1, so that a detachable threaded connection can also be achieved between the valve body 1 and the valve cover 6.

[0073] It should be noted that a third thread for connecting to an external component can be provided at the other end of the valve body 1. For example, an internal thread can be provided within the connection cavity 13 of the valve body 1, or an external thread can be provided on the outer wall of the other end of the valve body 1 (i.e., the end for connecting to the external component) to install the external component via a threaded connection. The external component can refer to a component of the cooling water circulation system in the liquid cooling system.

[0074] It should also be noted that a fourth thread for connecting to an external component can be provided at the other end of the valve cover 6. For example, an internal thread for connecting to an external component can be provided at the other end of the valve cover 6, so that the valve cover 6 can be connected to corresponding components of the water supply system of the liquid cooling system through the internal thread.

[0075] In addition, a sealing ring 5 may be provided at the connection between the valve cover 6 and the valve body 1. The sealing ring 5 can prevent liquid leakage at the connection between the valve cover 6 and the valve body 1 to ensure the sealing of the one-way valve.

[0076] In this embodiment, the guide seat 11 and the valve body 1 are integrally formed, so as to facilitate the processing and manufacturing of the guide seat 11 and the valve body 1 .

[0077] In order to further illustrate the use of the straight-through one-way valve provided by the present invention, an example is given below.

[0078] As shown in Figure 1, this is the one-way valve closed working state (i.e. closed state), that is, the one-way valve is in the working state when the water pressure in the cooling water circulation system of the liquid cooling system is normal. The pressure in the cooling water circulation system of the liquid cooling system is always in a high-pressure state. This pressure acts on the valve stem 3 and lifts the valve stem 3 together with the elastic reset member 2; the sealing ring 4 assembled on the valve stem 3 is subjected to the lifting force and is in close contact with the steel ring 61 on the valve cover 6 to play a sealing role; at the same time, the sealing ring 5 plays a role in sealing the connection between the valve body 1 and the valve cover 6.

[0079] As shown in Figure 2, the one-way valve is in the open state (i.e., the open state), which is the working state of the one-way valve when the water pressure in the cooling water circulation system of the liquid cooling system is too low. Specifically, after the cooling water circulation system of the liquid cooling system has been running for a period of time, the residual gas in the system is discharged by the system exhaust valve, causing the system pressure to drop; or the system may be partially leaking, causing the liquid in the system to slowly overflow. After a period of time, the liquid in the system decreases and the pressure also drops.

[0080] When the pressure drops to a certain level, it exceeds the rated force provided by the elastic return member 2, that is, the pressure of the fluid replenishment system in the direction of the valve cover 6 exceeds the sum of the pressure (water pressure) of the cooling water circulation system and the pressure of the elastic return member 2. At this time, the fluid replenishment system changes to a high-pressure area and the circulation system changes to a low-pressure area; this high pressure will push the valve stem 3 to open the one-way valve, and the seal between the sealing ring 4 and the steel ring 61 of the valve cover 6 will be released. At this time, the liquid in the fluid replenishment system will be added to the cooling water circulation system until the pressure in the cooling water circulation system and the sum of the elastic force of the elastic return member 2 reach a balance with the pressure of the fluid replenishment system. At this time, the sealing relationship between the sealing ring 4 and the steel ring 61 of the valve cover 6 is re-formed, and the one-way valve is closed.

[0081] When the one-way valve is in the open working state, the liquid in the fluid replenishment system will flow along the direction of the arrow in Figure 2. There is no matching relationship between the valve stem 3 and the valve cover 6 in the flow channel. The impurities in the liquid will flow normally along the flow channel and will not affect the normal movement of the valve stem 3 when the one-way valve is closed, that is, it will not affect the sealing between the sealing ring 4 and the valve cover 6.

[0082] In addition to the above-mentioned straight-through one-way valve, the present invention also provides a liquid cooling system including the straight-through one-way valve disclosed in the above embodiment.
