Description

Technical Field

[0001] The utility model relates to the technical field of valve body equipment, and more specifically to a locking type interlocking ball valve. Background Art

[0002] The snap-on quick-connect liquid-cooled interlocking ball valve is a ball valve that can be quickly connected and disassembled and is used in the field of liquid cooling. The two ball valves are connected by a snap-on connection, and the external connection can be in various forms such as threads, pagoda heads and chucks, ensuring the sealed fluid connection and disconnection between the two fluid passages. It can also be locked to prevent accidental disconnection when the passages are connected, thereby avoiding fluid leakage.

[0003] The two ends of the existing liquid cooling ball valve are often connected by welding. When a problem occurs in one pipeline and needs to be repaired or replaced, it cannot be handled quickly and in time, causing downtime of the liquid circuit part of the thermal management system. On the other hand, although the double ball valve card connection valve makes up for the disadvantage of not being able to quickly remove one end of the ball valve for maintenance, it lacks an anti-mistaken disassembly device, which can easily cause fluid leakage and cause greater losses, reducing the safety factor.

[0004] However, the current double ball valve interlocking structure has too many parts, the design is too complicated, and the valve body has too many machining steps, which makes the cost high, and the shear resistance of the interlocking rod when locked is small.

[0005] In summary, how to provide a double ball valve with a stable locking effect is a problem that needs to be urgently solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a locking type interlocking ball valve, which uses a small number of parts and has good locking stability.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A locking interlocking ball valve, comprising:

[0009] Two valve bodies, each of which is provided with a ball valve and connected by a clamping method, and each of which is provided with a locking hole and a positioning hole corresponding to the position;

[0010] A locking assembly is installed on the valve body, and the locking assembly includes a locking rod sliding in the locking hole. When the locking rod is inserted into the positioning hole, the locking of the two valve bodies is achieved.

[0011] The utility model further comprises:

[0012] A pin shaft, the pin shaft is mounted on the valve body and connected to the ball valve;

[0013] A handle is rotatably mounted on the pin shaft and is used to control the sliding of the locking rod in the locking hole.

[0014] Furthermore, the handle is provided with a pushing part and a rotating part, the pushing part is used to control the sliding of the locking rod, the pin shaft is located between the handle and the valve body, and the distance between the rotating part and the pin shaft is greater than the distance between the pushing part and the pin shaft.

[0015] The utility model further comprises:

[0016] A connecting rod, one end of which is hinged to the pushing portion, and the other end of which is hinged to the locking rod.

[0017] The utility model further has two positioning grooves on the valve body, and the two positioning grooves are respectively located at the end points of the rotation limits on both sides of the handle;

[0018] A steel ball rotates with the handle, and when the steel ball is located in the positioning groove, the position of the handle is fixed.

[0019] Furthermore, in the utility model, the valve body is provided with a slideway coaxially arranged with the pin shaft, and the two positioning grooves are respectively located at two ends of the slideway.

[0020] Furthermore, the handle is provided with a steel ball hole, and when the steel ball enters the steel ball hole, the handle can rotate freely.

[0021] The utility model further provides a control hole on the handle, the control hole is connected to the steel ball hole, a control rod slides in the control hole, and an annular groove is provided in the middle of the control rod.

[0022] Furthermore, in the utility model, a top spring is sleeved on the control rod to drive the control rod to slide outside the control hole.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The core of the utility model is to provide a locking type interlocking ball valve which uses a small number of parts and has good locking stability.

[0037] Please refer to Figure 1-Figure 7 A locking interlocking ball valve comprises two valve bodies 1 and a locking assembly 5. Ball valves 2 are arranged in the two valve bodies 1 and are connected by a snap-fitting manner. A locking hole 4 and a positioning hole 3 corresponding to the position are arranged on the valve body 1. The locking assembly 5 is installed on the valve body 1. The locking assembly 5 comprises a locking rod 501 sliding in the locking hole 4. When the locking rod 501 is inserted into the positioning hole 3, the two valve bodies 1 are locked.

[0038] It should be noted that in the embodiment of the utility model, the sizes of the positioning hole 3 and the locking hole 4 can be selected according to the size of the valve body 1, and the sizes of the positioning hole 3 and the locking hole 4 are the same.

[0039] When in use, the contact position structure of the two valve bodies 1 is the same. Both valve bodies 1 are provided with ball valves 2 and are connected by a snap-fitting manner. The valve body 1 is provided with locking holes 4 and positioning holes 3 corresponding to the positions. The pipeline switch is controlled by opening and closing the ball valve 2. The locking assembly 5 is installed on the valve body 1. The locking assembly 5 includes a locking rod 501 sliding in the locking hole 4. When the locking rod 501 is inserted into the positioning hole 3, the two valve bodies 1 are locked. That is to say, after the two valve bodies 1 are fixedly connected by a snap-fitting manner, the locking rod 501 sliding in the locking hole 4 is controlled by the locking assembly 5. After sliding, the locking rod 501 will enter the positioning hole 3 of the other valve body 1. At this time, the two valve bodies 1 are locked, thereby preventing the two ball valves 2 from rotating relative to each other after the snap-fitting is docked, that is, preventing the connection between the two ball valves 2 from being interrupted by misoperation when the pipeline is in an open state, thereby avoiding leakage caused by accidental operation.

[0040] Please refer to Figure 1-Figure 7In order to improve the use effect of the valve body 1, in some embodiments, the locking assembly 5 also includes a pin shaft 502 and a handle 505. The pin shaft 502 is installed on the valve body 1 and connected to the ball valve 2. The handle 505 is rotatably installed on the pin shaft 502 and is used to control the sliding of the locking rod 501 in the locking hole 4. That is to say, the locking rod 501 is controlled by the handle 505 to meet the fixed connection of the two valve bodies 1. At the same time, the handle 505 is fixed on the pin shaft 502, and the pin shaft 502 is rotatably installed on the valve body 1, so that the handle 505 can be used as a handle. When the handle 505 rotates, the ball valve 2 will be driven to rotate synchronously. Therefore, when the handle 505 rotates to control the locking rod 501 to be inserted into the positioning hole 3 of the other valve body 1, the ball valve 2 is opened. At this time, the pipeline passage is opened. Under the action of the fluid, there is a certain resistance to the ball valve 2, and effectively there is a certain resistance to the handle 505. Therefore, a certain fixing effect is achieved on the position of the locking rod 501, which reduces the malfunction of the locking rod 501 during the pipeline opening process, which is beneficial to the stability of the pipeline passage during use.

[0041] It should be noted that, in the embodiment of the utility model, the handle 505 and the pin 502 are fixedly connected by plugging through a limiting column.

[0042] Please continue to refer to Figure 1-Figure 7 In some embodiments, a pushing portion and a rotating portion are provided on the handle 505, and the pin 502 is located between the handle 505 and the valve body 1. The distance between the rotating portion and the pin 502 is greater than the distance between the pushing portion and the pin 502. That is, the rotating portion is used to provide power for the rotation of the handle 505, and the pushing portion is used to push the locking rod 501. By increasing the distance between the rotating portion and the pin 502 to make it greater than the distance between the pushing portion and the pin 502, the operating effect of the locking rod 501 is improved by increasing the operating force arm, and the resistance of the locking rod 501 during the locking process is improved.

[0043] Optionally, in some embodiments, the distance between the rotating portion and the pin shaft 502 is more than three times the distance between the pushing portion and the pin shaft 502 .

[0044] Optionally, in some embodiments, a handle is provided on the rotating portion to facilitate the user to perform grasping operation.

[0045] Please continue to refer to Figure 1-Figure 7 In some embodiments, the locking assembly 5 also includes a connecting rod 503, one end of the connecting rod 503 is hinged to the pushing portion, and the other end of the connecting rod 503 is hinged to the locking rod 501. The connecting rod 503 is used for the transition connection between the locking rod 501 and the handle 505, so that it can control the sliding of the locking rod 501 when the handle 505 rotates.

[0046] Optionally, in some embodiments, the pushing portion is a protruding structure protruding from the handle 505 , which is used to increase the driving radius of the connecting rod 503 while reducing the size of the handle 505 .

[0047] Please refer to Figure 1-Figure 7 In order to further improve the firmness of the locking rod 501 after being locked, in some embodiments, two positioning grooves 6 and steel balls 8 are provided on the valve body 1. The two positioning grooves 6 are respectively located at the end points of the rotation limit on both sides of the handle 505. The steel balls 8 rotate with the handle 505. When the steel balls 8 are located in the positioning grooves 6, the position of the handle 505 is fixed. That is to say, the steel balls 8 move with the handle 505, and the two positioning grooves 6 are respectively located at the end points of the rotation limit on both sides of the handle 505. Therefore, when the handle 505 moves to one of the positioning grooves 6, the steel balls 8 enter the positioning groove 6 to fix the position of the handle 505, thereby ensuring that the locking rod 501 is effectively locked and firmly locked.

[0048] Optionally, in some embodiments, the size of the positioning groove 6 can be selected according to the size of the steel ball 8 .

[0049] Optionally, in some embodiments, a steel ball hole 9 is provided on the handle 505. When the steel ball 8 enters the steel ball hole 9, the handle 505 can rotate freely. That is to say, the steel ball 8 can enter the steel ball hole 9 on the handle 505, so that the steel ball 8 moves out of the positioning groove 6, thereby canceling the restriction on the position of the handle 505. At this time, the handle 505 can rotate freely.

[0050] It should be noted that in the embodiment of the utility model, the diameter of the steel ball hole 9 is larger than the steel ball 8, so that the steel ball 8 can enter and exit freely.

[0051] Optionally, in some embodiments, a slideway 7 coaxially arranged with the pin shaft 502 is provided on the valve body 1, and two positioning grooves 6 are respectively located at both ends of the slideway 7. The slideway 7 is used to limit the steel ball 8 when the steel ball 8 rotates with the handle 505 to prevent the steel ball 8 from falling.

[0052] It should be noted that in the embodiment of the utility model, the depth of the positioning groove 6 is greater than the depth of the slideway 7 .

[0053] Please refer to Figure 1-Figure 7In order to further facilitate the control of the steel ball 8, in some embodiments, a control hole 10 is provided on the handle 505, and the control hole 10 is connected to the steel ball hole 9. A control rod 504 slides in the control hole 10, and an annular groove 507 is provided in the middle of the control rod 504. That is to say, the sliding of the control rod 504 in the control hole 10 realizes the position change of the annular groove 507 of the control rod 504. Therefore, when the annular groove 507 moves to the position of the steel ball hole 9, the steel ball 8 enters the annular groove 507, and the steel ball 8 is moved out of the positioning groove 6. After the position of the control rod 504 is moved, the steel ball 8 is squeezed out of the annular groove 507, so that the steel ball 8 enters the positioning groove 6, thereby fixing the position of the handle 505.

[0054] Please refer to Figure 1-Figure 7 In some embodiments, the control rod 504 is covered with a top spring 506 that drives the control rod 504 to slide outside the control hole 10. That is to say, the top spring 506 can control the control rod 504 to always keep the annular groove 507 away from the steel ball hole 9. Therefore, when a pre-tightening force is applied to the position of the steel ball 8, the fixing firmness of the handle 505 is further improved.

[0055] Optionally, in some embodiments, the side surface of the annular groove 507 is provided with a chamfer, that is, the chamfer is used to reduce the resistance when the steel ball 8 is pushed out of the annular groove 507, thereby improving the smoothness of the position change of the steel ball 8.

[0056] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0057] The above is a detailed introduction to a locking interlocking ball valve provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
