Description

Technical Field

[0001] This invention belongs to the field of fire protection accessories technology, and specifically relates to a control valve, a water stopper, and a water distributor. Background Technology

[0002] Firefighting equipment such as water stoppers, water distributors, and water guns are all equipped with on / off valves (or control valves). By turning the handle, the internal valve core rotates to open and close the water flow channel.

[0003] The applicant previously applied in China for an opening and closing device for a fire hose nozzle (publication number CN118178940A), which includes a slide tube, a plug, and a handle. The fire hose nozzle includes a body with a mounting cavity inside. A nozzle connected to the mounting cavity is located at the front end of the body. The slide tube is slidably disposed within the body. The plug is disposed within the body or the mounting cavity, and is adapted to the end of the slide tube. A water passage zone exists between the plug and the slide tube for the medium to pass through. The handle is connected to the slide tube and can drive the slide tube to slide, thereby adjusting the opening of the water passage zone. The slide tube has a clearance groove, and the body has a mounting hole with a turntable rotatably disposed within the mounting hole. The handle is connected to the turntable and has a lever eccentrically positioned on it. The inner end of the lever passes through the turntable and extends into the clearance groove. As the handle drives the turntable to rotate, the lever rotates around the central axis of the turntable. The lever then drives the slide tube to slide through the clearance groove, allowing the slide tube to move closer to or away from the plug, thereby adjusting the opening of the water passage zone.

[0004] This type of opening and closing device, also known as a control valve or switch valve, has a relatively large handle. Two rotary tables are respectively located on both sides of the gun body. The handle controls the rotation of two levers through the two rotary tables, thereby stably driving the slide tube to slide. The sliding tube requires many components. In other words, the overall lateral width of the assembled handle and valve body is large, and there are many components. This not only results in high production costs but also requires a lot of lateral storage space. This type of opening and closing device cannot be well adapted to commonly used fire-fighting equipment such as water stoppers and water diversion devices. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a control valve. The first technical problem this invention aims to solve is: how to improve the applicability of control valves on fire-fighting equipment.

[0006] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a water stop device. The second technical problem to be solved by this invention is: how to improve the applicability of the control valve on the water stop device.

[0007] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a water distributor. The third technical problem to be solved by this invention is: how to improve the applicability of the control valve on the water distributor.

[0008] The first technical objective of this invention can be achieved through the following technical solution: A control valve includes a valve body, a regulating pipe, a sealing plug, a rotary wheel, and a handle. The valve body has a communicating flow channel and an assembly hole. The regulating pipe is slidably disposed within the flow channel and has toothed grooves. The sealing plug is disposed within the valve body, and a water passage gap is provided between the sealing plug and the regulating pipe for fluid to pass through. The rotary wheel is rotatably disposed within the assembly hole and has a plurality of teeth distributed circumferentially, the teeth being adapted to the toothed grooves. The handle is directly or indirectly connected to the rotary wheel, and the handle can drive the rotary wheel to rotate, thereby controlling the sliding of the regulating pipe and adjusting the water passage gap.

[0009] Through the above technical solution, the handle drives the rotating wheel to rotate, causing the insert teeth to slide the regulating pipe, thereby adjusting the size of the water passage gap and thus regulating the water flow through the water passage gap. Since the regulating pipe adjusts the water passage gap by sliding without rotation, the high-pressure water flow is unlikely to directly act on the inner wall of the regulating pipe and force it to slide abnormally. This control valve will not experience abnormal opening and closing. Moreover, the insert teeth on the rotating wheel directly engage with the tooth groove, and the rotation of the rotating wheel drives the regulating pipe to slide. It is easy to assemble, has a small overall lateral width, and can be used as a switch valve on fire-fighting equipment such as water stoppers, water dividers, and water guns, thus having a wider range of applications.

[0010] In the control valve described above, the valve body has a mounting portion, the mounting hole is located inside the mounting portion, and the mounting portion is also provided with a mounting hole; a pivot is provided at the center of the rotary wheel, and the pivot is rotatably engaged with the mounting hole.

[0011] In the control valve described above, a bushing is rotatably disposed in the mounting hole, both ends of the pivot are adapted to the bushing, and the rotating wheel limits the circumferential movement of the pivot.

[0012] In the control valve described above, the handle is connected to both ends of the pivot.

[0013] In the control valve described above, the pivot passes through the handle, the handle has a positioning hole, the positioning hole has a positioning block, and the positioning block is detachably fixed to the pivot.

[0014] In the control valve described above, a cover plate is provided at the mounting hole to cover the mounting hole, and the cover plate is provided with a switch direction indicator.

[0015] In the control valve described above, a second bushing is detachably fixed in the mounting hole, and both ends of the pivot are rotatably engaged with the second bushing. The rotating wheel limits the circumferential movement of the pivot, or the rotating wheel is rotatably engaged with the pivot.

[0016] In the control valve described above, the handle is connected to the rotary wheel, and the handle can swing within the mounting hole.

[0017] In the control valve described above, the sidewall of the tooth groove is inclined towards the groove opening, and a convex ring is formed between two adjacent tooth grooves.

[0018] In the control valve described above, a damping mechanism is provided on the valve body. The damping mechanism includes a positioning bolt, a preload spring, and a ball bearing. The positioning bolt is connected to the valve body and has a mounting groove. The preload spring and the ball bearing are sequentially arranged in the mounting groove, and the preload spring presses the ball bearing against the rotating wheel.

[0019] In the control valve described above, a stroke groove corresponding to the damping mechanism is provided on the end face of the rotary wheel, and the preload spring presses the ball into the stroke groove; at least one positioning groove is provided at the bottom of the stroke groove, and the positioning groove allows the ball to enter.

[0020] In the control valve described above, at least two damping mechanisms are provided, with the two damping mechanisms distributed on both sides of the impeller, and the number of stroke grooves corresponds one-to-one with the number of damping mechanisms.

[0021] In the control valve described above, a support is provided inside the valve body, and the sealing plug is detachably fixed to the support. The sealing plug has a guide surface that protrudes toward the regulating pipe.

[0022] In the control valve described above, the end of the regulating pipe has a guide surface that guides the sealing plug. The sealing plug is inserted into the regulating pipe to seal the water passage gap, and the sealing plug and the regulating pipe are sealed by a sealing ring.

[0023] The second technical objective of this invention can be achieved through the following technical solution: A water stop device includes a first connector, a second connector, and the aforementioned control valve. The first connector and the second connector are respectively connected to both ends of the valve body, and both the first connector and the second connector are connected to the flow channel.

[0024] The third technical objective of this invention can be achieved through the following technical solution: A water distributor includes a water distributor body and the aforementioned control valve. The water distributor body has an inlet and at least two outlets, each of which is connected to the inlet. The valve body is connected to the inlet or an outlet.

[0025] In summary, the advantages of this invention compared to the prior art are as follows: The rotating wheel's center of rotation is horizontally positioned, minimizing the lateral space occupied by the valve body. A single rotation of the wheel directly drives the regulating pipe's sliding motion. The handle can connect to the wheel without spanning the valve body, allowing the small handle to rotate the wheel and thus change the distance between the regulating pipe and the sealing plug, thereby adjusting the size of the water passage gap. Compared to existing ball valves, this design offers lower production costs. Furthermore, the handle's direct connection to the wheel further reduces its lateral width. The guide surface on the sealing plug not only guides the fluid within the water passage gap but also ensures a uniform and gradual decrease in fluid flow as the regulating pipe closes the gap, preventing water hammer within the control valve. Moreover, this switch is smaller overall, requires fewer components, and is easier to assemble. It can be used as a switching valve on fire-fighting equipment such as stop valves, distributors, and water guns, broadening its applicability. This control valve also prevents abnormal displacement of the regulating pipe caused by high-pressure water flow.

[0026] In addition, the damping mechanism presses against the impeller, increasing the impeller's rotational resistance, which in turn indirectly increases the sliding resistance of the regulating pipe, preventing the regulating pipe from sliding abnormally due to the force of the high-pressure water flow and maintaining the opening of the water passage gap.

[0027] The positioning groove positions the ball bearing, requiring the handle to apply additional force to disengage the ball bearing from the positioning groove, further increasing the rotational resistance of the wheel. The positioning groove can also be used as a gear slot, with each positioning groove corresponding to the opening of the water passage gap, increasing the rotational feel of the handle and effectively improving the user experience.

[0030] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example 1:

[0031] A control valve, such as Figures 1-8As shown, the valve includes a valve body 100, a regulating pipe 200, a sealing plug 300, a rotary wheel 400, and a handle 500. The valve body 100 has a connected flow channel 110 and an assembly hole 120. The valve body 100 has a mounting part 130, and the assembly hole 120 is located inside the mounting part 130. The mounting part 130 also has an installation hole 131. The regulating pipe 200 is slidably disposed in the flow channel 110. Several toothed grooves 210 are provided at intervals on the outside of the regulating pipe 200. The sealing plug 300 is disposed inside the valve body 100. There is a water passage gap 220 between the sealing plug 300 and the regulating pipe 200 for fluid to pass through. The rotating wheel 400 is rotatably mounted in the mounting hole 120. The rotating wheel 400 has several teeth 410 distributed circumferentially, and the teeth 410 are adapted to the tooth groove 210. The handle 500 is directly or indirectly connected to the rotating wheel 400. The handle 500 can drive the rotating wheel 400 to rotate, thereby controlling the sliding of the regulating pipe 200 and adjusting the opening of the water passage gap 220. The larger the opening of the water passage gap 220, the greater the fluid flow rate that can pass through. Conversely, the smaller the opening of the water passage gap 220, the smaller the fluid flow rate that can pass through. After the sealing plug 300 blocks the regulating pipe 200, the fluid in the flow channel 110 stops flowing.

[0032] A shaft hole 420 is provided at the center of the rotating wheel 400, and a pivot 421 is provided in the shaft hole 420. The pivot 421 is rotatably engaged with the mounting hole 131. In other words, the pivot 421 is arranged horizontally and perpendicular to the rotating wheel 400, and the pivot 421 is the rotation center of the rotating wheel 400.

[0033] like Figures 2-6 As shown, specifically, a bushing 1311 is rotatably disposed inside the mounting hole 131, and both ends of the pivot 421 are adapted to the inner hole of the bushing 1311. In this embodiment, the cross-sectional shape of the shaft hole 420 is triangular or polygonal, and the cross-sectional shape of the pivot 421 is adapted to the shaft hole 420. The pivot 421 is circumferentially limited by the shaft hole 420, so that the rotating wheel 400 can drive the pivot 421 and the bushing 1311 to rotate synchronously.

[0034] Both ends of the pivot 421 extend out of the bushing 1311 and are connected to the handle 500, that is, the handle 500 is indirectly connected to the wheel 400 through the pivot 421.

[0035] Both ends of the pivot 421 pass through the handle 500. The handle 500 has positioning holes 510, and positioning blocks 520 are located within the positioning holes 510. The positioning blocks 520 are fixed to the pivot 421 with bolts. Furthermore, the positioning blocks 520 have limiting grooves 521 that fit the ends of the pivot 421. The limiting grooves 521 circumferentially limit the pivot 421, allowing the pivot 421 to rotate synchronously with the positioning blocks 520, the handle 500, and the rotating wheel 400. The handle 500 is connected to the pivot 421 via the positioning blocks 520 to distribute the rotational torque exerted by the handle 500 on the pivot 421, preventing breakage at the connection between the handle 500 and the pivot 421.

[0036] like Figures 1-4 As shown, a cover plate 132 is provided at the mounting hole 131 to cover the mounting hole 131. The cover plate 132 is provided with a switch direction indicator 1321 and a flow rate indicator 1322. The switch direction indicator 1321 indicates whether the handle 500 is swinging in the open or closed direction, and the flow rate indicator 1322 indicates the flow rate corresponding to the swing direction of the handle 500. Either the switch direction indicator 1321 or the flow rate indicator 1322 can be selected.

[0037] like Figures 3-6 As shown, the grooves 210 are distributed in a ring on the regulating pipe 200. The sidewalls of the grooves 210 are inclined towards the groove opening, so that the grooves 210 have a large opening, making it easier for the insert teeth 410 to be inserted and removed from the grooves 210. A convex ring 211 is formed between two adjacent grooves 210. In this embodiment, the outer diameter of the convex ring 211 is larger than the outer diameter of the regulating pipe 200. Each convex ring 211 can enhance the structural strength of the regulating pipe 200, and the arrangement of the grooves 210 will not encroach on the internal space of the regulating pipe 200, ensuring that the interior of the regulating pipe 200 is smooth and will not be interfered with by the fluid. In some embodiments, the outer diameter of the convex ring 211 is equal to the outer diameter of the regulating pipe 200.

[0038] like Figures 2-5 As shown, a damping mechanism 600 is provided on the valve body 100. The damping mechanism 600 includes a positioning bolt 610, a preload spring 620, and a ball bearing 630. The positioning bolt 610 is connected to the valve body 100 and has a mounting groove 611 facing the rotary wheel 400. The preload spring 620 and the ball bearing 630 are sequentially arranged in the mounting groove 611. One end of the preload spring 620 abuts against the mounting groove 611, and the other end abuts against the ball bearing 630, so that the preload spring 620 presses the ball bearing 630 against the rotary wheel 400.

[0039] The end face of the rotary wheel 400 is provided with a stroke groove 430 corresponding to the damping mechanism 600. The preload spring 620 presses the ball 630 into the stroke groove 430. At least one positioning groove 431 is provided at the bottom of the stroke groove 430, which allows the ball 630 to enter. The positioning grooves 431 are distributed at intervals in the stroke groove 430. When the rotary wheel 400 rotates, the ball 630 rolls along the bottom of the stroke groove 430. After the positioning groove 431 approaches the ball 630, the preload spring 620 pushes the ball 630 into the positioning groove 431. Only by increasing the thrust applied to the handle 500 can the rotary wheel 400 continue to rotate, forcing the ball 630 to leave the positioning groove 431 and re-enter the stroke groove 430. In other words, after the ball 630 enters the positioning groove 431, the rotational resistance of the rotary wheel 400 will further increase, making it difficult for the regulating pipe 200 to move abnormally due to the impact of high-pressure water flow.

[0040] At least two damping mechanisms 600 are provided, and the number of stroke grooves 430 corresponds one-to-one with the number of damping mechanisms 600. The two damping mechanisms 600 are distributed on both sides of the rotating wheel 400 to avoid uneven force distribution when the rotating wheel 400 rotates. In some embodiments, only one damping mechanism 600 is provided.

[0041] A bracket 140 is provided inside the valve body 100, through which fluid can pass. A sealing plug 300 is detachably fixed to the bracket 140. The sealing plug 300 has a guide surface 310 protruding towards the regulating pipe 200. The guide surface 310 guides the water flow entering the water passage 220, reducing the resistance of the sealing plug 300 to fluid movement. Furthermore, when the sealing plug 300 is inserted into the end of the regulating pipe 200, the guide surface 310 also guides the sealing plug 300, ensuring that the sealing plug 300 accurately seals the regulating pipe 200. Further, the end of the sealing plug 300 away from the regulating pipe 200 has a flow-stabilizing slope 320 or a weight-reducing groove 330. Figures 3-8 As shown, in some embodiments, the support 140 can be positioned close to the inlet or outlet of the flow channel 110, as long as the guide surface 310 faces the inlet direction.

[0042] like Figures 3-4 As shown, the end of the regulating pipe 200 has a guide surface 230. When the sealing plug 300 is inserted into the regulating pipe 200, the guide surface 230 further guides the sealing plug 300, and the sealing plug 300 blocks the end of the regulating pipe 200, thus sealing the water passage gap 220. The sealing plug 300 and the regulating pipe 200 are sealed by a sealing ring 341. Specifically, the outer wall of the sealing plug 300 is provided with a sealing groove 340, and the sealing ring 341 is disposed in the sealing groove 340. When the sealing plug 300 is inserted into the regulating pipe 200, the sealing ring 341 seals the sealing plug 300 and the regulating pipe 200.

[0043] like Figure 2, Figure 6 , Figure 7 As shown, the valve body 100 includes a main body 150 and a connecting pipe 160, which are detachably connected. Alternatively, the valve body 100 can be divided into multiple detachable components, or the valve body 100 can be used as a single, independent component.

[0044] like Figure 2 , Figure 8 As shown, in at least one embodiment, the body 150 and / or the connecting pipe 160 are provided with a threaded interface 170. Example 2:

[0045] The difference between Example 2 and Example 1 is as follows: Figures 9-13 As shown, a bushing 1312 is detachably fixed inside the mounting hole 131, and both ends of the pivot 421 are rotatably engaged with the bushing 1312; the detachable fixing method is snap-fit ​​or threaded connection.

[0046] Furthermore, the handle 500 is threadedly connected to the rotating wheel 400 or integrally formed, meaning the handle 500 is directly connected to the rotating wheel 400. The handle 500 swings within the mounting hole 120 around the pivot 421, thus driving the rotating wheel 400 to rotate. In this embodiment, the pivot 421 is only used as the center of rotation. The cross-sectional shape of the pivot 421 can be polygonal or cylindrical, and the cross-sectional shape of the shaft hole 420 is adapted to the pivot 421, allowing the pivot 421 to rotate synchronously with the rotating wheel 400, or the pivot 421 and the rotating wheel 400 to rotate in conjunction. Neither of these two methods of engagement affects the normal rotation of the rotating wheel 400.

[0047] The working principle of a control valve: The user holds the handle 500 and pushes the handle 500 to drive the rotating wheel 400 to rotate synchronously, so that the insert 410 moves the regulating tube 200 to slide, thereby adjusting the size of the water passage gap 220 and thus adjusting the flow rate of the fluid flowing through the water passage gap 220.

[0048] Since the regulating pipe 200 adjusts the water passage gap 220 by sliding, it does not require the rotation method of a ball valve. The high-pressure water flow is difficult to directly act on the inner wall of the regulating pipe 200, forcing the regulating pipe 200 to slide abnormally. Therefore, the control valve will not have abnormal opening and closing phenomena. During the process of the regulating pipe 200 moving towards the sealing plug 300 and closing the water passage gap 220, the fluid flow rate can be reduced gradually and uniformly, thereby avoiding the water hammer effect in the control valve.

[0049] Furthermore, the insert teeth 410 on the rotating wheel 400 directly engage with the tooth groove 210. Rotating the rotating wheel 400 with the insert teeth 410 drives the regulating pipe 200 to slide. The pivot 421 is set horizontally, and the handle 500 is smaller in size and has a smaller horizontal width, making it easy to assemble. It can be used as a switch valve on fire-fighting equipment such as water stoppers, water dividers, and water guns, and has a wider range of applications.

[0050] The damping mechanism 600 presses against the impeller 400, increasing the rotational resistance of the impeller 400, thereby indirectly increasing the sliding resistance of the regulating pipe 200, further preventing the regulating pipe 200 from sliding abnormally due to the force of the high-pressure water flow, thus maintaining the opening of the water passage gap 220.

[0051] A type of water stopper, such as Figures 14-16 As shown, this water stop includes connector 710, connector 720, and the aforementioned control valve. Connector 710 and connector 720 are respectively connected to both ends of the valve body 100, and both connector 710 and connector 720 are connected to the flow channel 110, with the guide surface 310 facing the water inlet direction. In this embodiment, connector 710 and connector 720 are quick-release connectors or threaded connectors.

[0052] A type of water distributor, such as Figure 17 As shown, the device includes a water distributor body 800 and the aforementioned control valve. The water distributor body 800 has an inlet 810 and at least two outlets 820, with each outlet 820 connected to the inlet 810. The valve body 100 is connected to either the inlet 810 or the outlet 820.

[0053] The specific embodiments described herein are merely illustrative of the spirit of the invention; those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, but without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
