[0002] Fire valves are crucial control accessories in fire protection pipelines in industrial and building applications. A fire valve consists of a valve body and an actuator. The valve body connects to the pipeline, while the actuator connects to the valve body, controlling the opening and closing of the valve. A valve box typically consists of a housing and multiple fire valves housed within it. The fire valves are closely arranged, and their actuators are secured to the valve bodies via connecting plates and multiple screws. Due to the limited space within the valve box, tightening the screws on the actuators and valve bodies is inconvenient. Furthermore, disassembling and assembling the actuators and valve bodies is difficult when inspecting, maintaining, or replacing the fire valves, resulting in low efficiency in fire valve assembly and disassembly. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to provide a connection mechanism for fire valves, fire valves and valve boxes, which can improve the efficiency of fire valve assembly and disassembly.

[0004] To solve the above-mentioned technical problems, this utility model provides a connecting mechanism for a fire valve, comprising: a first connecting member, the first connecting member including a connecting seat and a protrusion, the side wall of the protrusion being provided with a first locking block; a second connecting member, the second connecting member including a first through hole, the second connecting member being engaged with the first connecting member, and the protrusion penetrating through the first through hole; a movable member, the movable member including a second through hole, the end of the protrusion being located within the second through hole, the movable member being able to slide relative to the second connecting member, the side wall of the second through hole being provided with a second locking block, the movement path of the second locking block being located between the connecting seat and the first locking block, and the second locking block being able to abut against the first locking block.

[0006] In one embodiment of the present invention, the first locking block is located on the side wall of the protrusion away from the connecting seat, and the second locking block is located on the side wall of the second through hole near the connecting seat.

[0007] In one embodiment of the present invention, the sidewall of the protrusion is provided with a plurality of first locking blocks, the sidewall of the second through hole is provided with a plurality of second locking blocks, a first channel for the passage of the second locking blocks is formed between two adjacent first locking blocks, and a second channel for the passage of the first locking blocks is formed between two adjacent second locking blocks.

[0008] In one embodiment of this utility model, the movable member is connected to a handle, and the handle is provided with a locking hole on the side near the second connecting member.

[0015] This utility model discloses a connecting mechanism for a fire valve, a fire valve, and a valve box. The two ends of a movable component abut against a second connecting component and an actuator, respectively. By rotating the movable component to bring the first locking block into contact with the second locking block, friction exists between the two blocks, thus fixing the valve body and actuator relatively.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figures 1 to 6As shown, a connecting mechanism for a fire valve according to this utility model includes: a first connecting member 1, which includes a connecting seat 14 and a protrusion 11, and a first locking block 12 provided on the side wall of the protrusion 11; a second connecting member 2, which includes a first through hole 27, and the second connecting member 2 is engaged with the first connecting member 1, with the protrusion 11 penetrating through the first through hole 27; and a movable member 3, which includes a second through hole 36, with the end of the protrusion 11 located within the second through hole 36, and the movable member 3 and the second connecting member 2 being able to slide relative to each other, and a second locking block 32 provided on the side wall of the second through hole 36, the movement path of the second locking block 32 being located between the connecting seat 14 and the first locking block 12, and the second locking block 32 being able to abut against the first locking block 12.

[0028] In this embodiment, a connecting mechanism for a fire valve is provided. The valve body 4 is connected to the connecting seat 14, and the actuator 5 is connected to the second connecting member 2 and abuts against the movable member 3. When the valve body 4 needs to be connected to the actuator 5, the actuator 5 is moved so that the protrusion 11 of the first connecting member 1 passes through the first through hole 27 of the second connecting member 2 until the end of the protrusion 11 is located in the second through hole 36. At this time, the first locking block 12 and the second locking block 32 are staggered in the axial direction of the second through hole 36. Then, the movable member 3 is rotated so that the second locking block 32 moves between the connecting seat 14 and the first locking block 12. At this time, the second locking block 32 abuts against the first locking block 12, thereby fixing the valve body 4 and the actuator 5 relative to each other. The movable part 3 abuts against the second connecting part 2 and the actuator 5 at both ends respectively. After rotating the movable part 3 so that the first locking block 12 abuts against the second locking block 32, there is friction between the first locking block 12 and the second locking block 32, so that the valve body 4 and the actuator 5 can be relatively fixed. Then, by rotating the movable part 3, the connection and disassembly of the valve body 4 and the actuator 5 can be completed, which improves the disassembly and assembly efficiency of the fire valve.

[0029] Reference Figure 4As shown, the first connector 1 includes a connecting seat 14 and a protrusion 11. Both the connecting seat 14 and the protrusion 11 are cylindrical. The diameter of the protrusion 11 is smaller than the diameter of the connecting seat 14, and the protrusion 11 is located at the middle of one end of the connecting seat 14. The height of the connecting seat 14 is smaller than the height of the protrusion 11. A first locking block 12 is provided on the sidewall of the protrusion 11. The width of the first locking block 12 gradually increases away from the protrusion 11, and the side of the first locking block 12 away from the protrusion 11 is arc-shaped. The first locking block 12 is located on the sidewall of the protrusion 11 away from the connecting seat 14. Preferably, the sidewall of the protrusion 11 is provided with multiple first locking blocks 12, which are centrally symmetrically arranged about the center line of the protrusion 11. In this embodiment, the protrusion 11 has four first locking blocks 12. A first channel 13 for the passage of a second locking block 32 is formed between two adjacent first locking blocks 12. Preferably, the first connector 1 is integrally formed, thereby improving the overall strength of the first connector 1.

[0030] Reference Figures 2 to 5 As shown, the second connector 2 includes a first through hole 27. The second connector 2 engages with the first connector 1, and the protrusion 11 passes through the first through hole 27. Specifically, a plurality of positioning posts 26 are provided on the side of the second connector 2 that abuts against the connecting seat 14. Positioning holes 15 are provided on the connecting seat 14 at positions corresponding to the positioning posts 26. The positioning holes 15 are located axially between two adjacent first locking blocks 12 of the protrusion 11. The positioning posts 26 can engage with the positioning holes 15, thereby engaging the second connector 2 with the first connector 1 and positioning the second connector 2. The diameter of the first through hole 27 is greater than the maximum distance between the two first locking blocks 12, so that the first locking blocks 12 and the protrusion 11 can pass through the first through hole 27. Preferably, the second connector 2 is integrally formed, thereby improving the overall strength of the second connector 2.

[0031] Reference Figure 2 , Figure 3 and Figure 6As shown, the movable part 3 includes a second through hole 36, and the end of the protrusion 11 is located inside the second through hole 36, thereby preventing the end of the protrusion 11 from abutting against the actuator 5, which would reduce the friction between the first locking block 12 and the second locking block 32, and also preventing damage to the actuator 5 and the protrusion 11. The movable part 3 and the second connecting part 2 can slide relative to each other. Specifically, the second connecting part 2 has a groove 23 located on the edge of the first through hole 27, and a guide block 37 is provided at the end of the movable part 3 that abuts against the second connecting part 2. The second through hole 36 passes through the guide block 37, so that the guide block 37 is annular in shape. The end of the guide block 37 fits against the bottom of the groove 23, and the side wall of the guide block 37 fits against the side wall of the groove 23. The guide block 37 and the groove 23 are slidably connected, so that the movable part 3 and the second connecting part 2 can slide relative to each other, that is, the movable part 3 can rotate. The diameter of the second through hole 36 is greater than the maximum distance between the two first locking blocks 12, so that the end of the protrusion 11 and the first locking blocks 12 can both be located within the second through hole 36. A second locking block 32 is provided on the side wall of the second through hole 36. The second locking block 32 is located on the side wall of the second through hole 36 near the end of the connecting seat 14, and the movement path of the second locking block 32 is between the connecting seat 14 and the first locking block 12. By rotating the movable member 3, the second locking block 32 and the side of the first locking block 12 that are close to each other abut against each other. Preferably, the side wall of the second through hole 36 is provided with multiple second locking blocks 32, the number of which is the same as the number of first locking blocks 12. The multiple second locking blocks 32 are centrally symmetrically arranged about the center line of the protrusion 11. In this embodiment, four second locking blocks 32 are provided on the side wall of the second through hole 36. Two adjacent second locking blocks 32 form a second channel 33 for the passage of the first locking block 12. By moving the second connecting member 2 and the movable member 3, the first locking block 12 can move within the second channel 33, and the second locking block 32 can move along the first channel 13 until the rotation path of the second locking block 32 is located between the first locking block 12 and the connecting seat 14. Then, by rotating the movable member 3, the second locking block 32 abuts against the first locking block 12. Preferably, the movable member 3 is integrally formed, thereby improving the overall strength of the movable member 3.

[0032] The movable part 3 is connected to a handle 31, which extends radially along the second through hole 36 and away from the center line of the second through hole 36. A locking hole 35 is provided on the side of the handle 31 near the second connecting part 2. A limiting block is provided on the second connecting part 2, and the limiting block can engage with the locking hole 35. Specifically, the rotation path of the limiting block corresponds to that of the locking hole 35. The second connecting part 2 has a groove 24, and a mounting hole is provided at the bottom of the groove 24. The limiting block is slidably connected to the mounting hole. An elastic element is connected between the end of the limiting block and the bottom of the mounting hole. The elastic element can be considered as a spring, allowing the limiting block to move axially along the mounting hole. When the elastic element is in its natural state, the top of the limiting block is located outside the mounting hole, and the height of the limiting block protruding from the mounting hole is greater than the depth of the groove 24. A guide groove 34 is provided on the side of the handle 31 near the second connecting member 2. The depth of the guide groove 34 gradually decreases towards the end near the locking hole 35, so that the bottom of the guide groove 34 forms a guide slope, and the limiting block is located on the moving path of the guide groove 34. During the rotation of the handle 31, the guide slope abuts against the limiting block and drives the limiting block to move into the mounting hole. At this time, the elastic element is compressed until the limiting block corresponds to the position of the locking hole 35. Then, the elastic element drives the limiting block to move, so that the limiting block extends into the locking hole 35, thereby locking the limiting block with the locking hole 35, and thus fixing the position of the handle 31 and the movable member 3. Preferably, the top of the limiting block is arc-shaped, so as to facilitate the limiting block to disengage from the locking hole 35 by rotating the handle 31. Preferably, there are two limiting blocks, namely a first limiting block 21 and a second limiting block 22. When the first limiting block 21 is engaged with the locking hole 35, the first locking block 12 and the second locking block 32 are staggered in the axial direction of the protrusion 11, that is, the fire valve connection mechanism is in the unlocked state. When the second limiting block 22 is engaged with the locking hole 35, the first locking block 12 and the second locking block 32 abut against each other, that is, the fire valve connection mechanism is in the locked state.

[0033] In use, the valve body 4 is connected to the connecting seat 14, and the actuator 5 is connected to the second connecting member 2 and abuts against the movable member 3. When the valve body 4 needs to be connected to the actuator 5, the actuator 5 is moved so that the protrusion 11 of the first connecting member 1 passes through the first through hole 27 of the second connecting member 2 until the end of the protrusion 11 is located in the second through hole 36. At this time, the first locking block 12 and the second locking block 32 are staggered in the axial direction of the second through hole 36. Then, the handle 31 is pushed to make the movable member 3 rotate until the handle 31 locking hole 35 engages with the second limiting block 22. At this time, the second locking block 32 abuts against the first locking block 12, and the valve body 4 and the actuator 5 are relatively fixed. When the valve body 4 needs to be separated from the actuator 5, pull the handle 31 to rotate the movable part 3 until the handle 31 locking hole 35 engages with the first limiting block 21. At this time, the first locking block 12 and the second locking block 32 are staggered in the axial direction of the protrusion 11. Finally, move the actuator 5 to disengage the protrusion 11 of the first connecting member 1 from the first through hole 27 of the second connecting member 2.

[0034] Reference Figure 1 , Figure 4 and Figure 5 As shown, this utility model also provides a fire valve, including the aforementioned fire valve connection mechanism. The fire valve can be considered as an electric ball valve. The fire valve also includes a valve body 4 and an actuator 5. The valve body 4 is connected to the actuator 5 through the fire valve connection mechanism. Specifically, the valve body 4 includes a mounting plate 6, which has a first connection hole 61. A connecting seat 14 has a second connection hole 16. The first connection hole 61 and the second connection hole 16 are connected by bolts, thereby connecting the mounting plate 6 to the connecting seat 14. The actuator 5 is connected to multiple connecting posts. The second connecting member 2 has a third connection hole 25 corresponding to the position of the connecting post. The connecting post and the third connection hole 25 are connected by bolts, thereby connecting the connecting post to the second connecting member 2, and thus connecting the actuator 5 to the second connecting member 2. The side of the actuator 5 used for mounting the connecting post abuts against the movable member 3. Through the connection between the second connecting member 2 and the connecting post, the movable member 3 is clamped between the actuator 5 and the second connecting member 2, and the movable member 3 is slidably connected to the actuator 5, thereby allowing the movable member 3 to rotate.

[0035] Reference Figure 7 and Figure 8 As shown, this utility model also provides a valve box, which includes the aforementioned fire valve, a box body (not shown), a manifold 71, and a bellows 7. The bellows 7 penetrates the box body, and the manifold 71 is connected to the bellows 7. Multiple fire valves are arranged along the center line of the manifold 71 and connected to the manifold 71. Both the fire valves and the manifold 71 are located inside the box body. Specifically, the manifold 71 is provided with multiple connectors 72, and the valve body 4 of the fire valve is connected to the connectors 72, thereby connecting the valve body 4 to the manifold 71. The manifold 71 is also connected to a connecting plate 8, which is connected to the inner wall of the box body. Preferably, the valve box may include multiple bellows 7 and manifold 71.

[0036] This utility model discloses a connecting mechanism for a fire valve, a fire valve, and a valve box. The movable part 3 abuts against the second connecting part 2 and the actuator 5 at both ends. When the movable part 3 is rotated to abut against the first locking block 12 and the second locking block 32, friction exists between them, thus fixing the valve body 4 and the actuator 5 relatively. Therefore, the connection and disassembly of the valve body 4 and the actuator 5 can be completed by rotating the movable part 3, improving the efficiency of fire valve assembly and disassembly. The first limiting block 21 and the second limiting block 22 fix the position of the handle 31, thereby fixing the position of the movable part 3 and ensuring a stable engagement between the first locking block 12 and the second locking block 32.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
