Description

Technical Field

[0001] This utility model relates to the field of fluid control components for water supply systems, and in particular to an operating valve for a water supply system. Background Technology

[0002] Water supply systems are the infrastructure of municipal engineering and industrial production. As a key component in the system that controls the flow of water and regulates the flow rate, the operating stability of the valve directly affects the safety of the pipeline and the user experience. It needs to be adapted to the water pressure change requirements under different working conditions.

[0003] The operating valves in existing water supply systems typically consist of a valve body, an internal valve core, and a matching operating mechanism. The valve body is mostly a hollow cavity structure, with its inlet and outlet sealed to the water supply pipeline to form a water flow channel. The valve core is installed inside the valve body cavity and, by changing its relative position to the valve body channel (such as rotation or lifting), realizes the opening and closing of the water flow or the regulation of the flow rate.

[0004] However, existing operating valves have the following drawbacks: When the main water valve in the water supply system is opened, the water pressure in the main pipeline experiences a severe disturbance. This disturbance is quickly transmitted to the connected bypass pipeline, causing instantaneous pressure fluctuations in the bypass pipeline. If the bypass pipeline's operating valve was originally closed, the pressure fluctuations will cause the bypass pipeline's operating valve to rotate slightly. This rotation will generate high-frequency vibrations in the operating mechanism connected to the valve core, resulting in noticeable noise in the water supply pipeline. Furthermore, it will reduce the sealing performance of the operating valve, increasing the risk of leakage. Utility Model Content

[0005] This application provides an operating valve for a water supply system, which solves the problem in the prior art where the main water pressure disturbance causes slight rotation of the bypass operating valve and high-frequency vibration of the operating mechanism, thus avoiding the noise generated in the pipeline and reducing the risk of water leakage.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an operating valve for a water supply system, including a valve body and a valve core installed in the valve body. The valve core is connected to an operating mechanism, which includes a rotating shaft connected to the valve core and a fixed seat fixed to the outer periphery of the rotating shaft. A rotating disk that can only move vertically relative to the fixed seat is assembled below the fixed seat. The outer periphery of the rotating disk is provided with toothed grooves evenly distributed along its center circumference. A toothed block adapted to the toothed grooves is fixed on one side of the valve body. When the rotating disk moves downward relative to the fixed seat, the toothed block can be engaged in the toothed groove to restrict the circumferential rotation of the rotating disk. When the rotating disk moves upward relative to the fixed seat, the toothed block can disengage from the toothed groove to release the circumferential restriction on the rotating disk.

[0007] In use, when it is necessary to adjust the flow or volume of water in the water supply system, the rotating disk is first moved upwards, causing the toothed grooves arranged along the central circumference of the rotating disk to disengage from the toothed blocks fixed on one side of the valve body, thus releasing the circumferential restriction of the rotating disk by the toothed blocks. Then, the rotating shaft connected to the valve core is rotated, causing the valve core to move synchronously, thereby adjusting the water flow, closing the circuit, or adjusting the flow rate. After the valve core is adjusted to the target working state, the rotating disk is moved downwards, causing the toothed blocks on the valve body to re-engage into the toothed grooves of the rotating disk. The cooperation between the toothed blocks and the toothed grooves restricts the circumferential rotation of the rotating disk, thereby fixing the position of the rotating shaft and the valve core, preventing the valve core from shifting due to changes in pipeline water pressure. Because the cooperation between the rotating disk and the toothed blocks on the valve body can circumferentially lock the rotating shaft after the valve core adjustment is completed, it prevents the disturbance to the valve core caused by the main water supply system pressure fluctuations transmitted to the bypass. Therefore, the valve core will not rotate slightly due to water pressure fluctuations, and the operating mechanism will not generate high-frequency vibrations, effectively avoiding noise and leakage risks caused by high-frequency vibrations of the operating mechanism.

[0008] As a further improvement to the above solution, the rotating disk includes a toothed disk with toothed grooves on its outer periphery and an annular ring coaxially fixed to the center of the upper end face of the toothed disk; the lower end face of the fixed seat is provided with an annular groove adapted to the annular ring, and the annular ring can be embedded in the annular groove and slide vertically along the groove wall; the side wall of the annular groove is provided with a vertical groove, and the outer side wall of the annular ring is provided with a protrusion adapted to the groove, and the protrusion can slide vertically in the groove; thus, through the cooperation of the groove and the protrusion, a stable guide is provided for the vertical movement of the rotating disk relative to the fixed seat, and the circumferential rotation of the rotating disk relative to the fixed seat is restricted.

[0009] As a further improvement to the above solution, two symmetrically arranged vertical support rods are fixed on the upper end face of the toothed disc, and the top ends of the two vertical support rods are connected to a horizontal limiting rod, which spans across the top of the rotating shaft; a strip-shaped limiting bolt is rotatably installed on the upper end face of the rotating shaft, and when the limiting bolt rotates to a preset position, it can span across the top of the horizontal limiting rod to restrict the upward movement of the horizontal limiting rod.

[0010] As a further improvement to the above solution, one end of the limiting bolt is rotatably connected to the upper end face of the rotating shaft via a pin, and the other end is fixed with a magnet at its bottom. When the limiting bolt spans above the transverse limiting rod, the magnet can be attracted and fixed to the upper end face of the rotating shaft. Thus, after the rotating disk moves down and the tooth block is inserted into the tooth groove, the position of the rotating disk is fixed by the limiting action of the limiting bolt on the transverse limiting rod, preventing it from accidentally moving upward and causing the tooth block to detach from the tooth groove.

[0011] As a further improvement to the above solution, a spring is installed in the annular groove of the fixed seat. The upper end of the spring is fixed to the top wall of the annular groove, and the lower end is fixed to the upper surface of the annular ring. When the limiting bolt spans across the horizontal limiting rod and the toothed block is engaged in the toothed groove, the spring is in a stretched state. The stretched spring can generate a continuous upward traction force on the rotating disk. In conjunction with the limiting bolt limiting the horizontal limiting rod, the position of the rotating disk can be fixed to prevent the toothed block from separating from the toothed groove. When it is necessary to release the limit, simply rotate the limiting bolt to disengage from the horizontal limiting rod. The traction force of the spring can drive the rotating disk to move automatically upward, so that the toothed block separates from the toothed groove. There is no need to manually move the rotating disk, which improves the convenience of operation.

[0012] As a further improvement to the above solution, multiple telescopic rods are vertically connected between the top wall of the annular groove of the fixed seat and the upper end face of the annular ring. The telescopic rods include an inner rod body and an outer tube body. The outer tube body is nested outside the inner rod body and can extend and retract vertically relative to the inner rod body.

[0013] As a further improvement to the above solution, the spring is nested outside the telescopic rod, and the extension and retraction direction of the spring is consistent with the extension and retraction direction of the telescopic rod.

[0014] As a further improvement to the above solution, the upper end of the rotating shaft is connected to a ring-shaped handle, and the inner ring of the handle is fixedly connected to the outer periphery of the upper end of the rotating shaft through multiple evenly distributed connecting rods; the handle can provide the operator with a more comfortable gripping point for applying force.

[0015] As can be seen from the above technical solutions, this utility model has at least the following technical effects or advantages: In use, when it is necessary to adjust the flow or volume of water in the water supply system, the rotating disk is first moved upwards, causing the toothed grooves arranged along the central circumference of the rotating disk to disengage from the toothed blocks fixed on one side of the valve body, thus releasing the circumferential restriction of the rotating disk by the toothed blocks. Then, the rotating shaft connected to the valve core is rotated, causing the valve core to move synchronously, thereby adjusting the water flow, closing the circuit, or adjusting the flow rate. After the valve core is adjusted to the target working state, the rotating disk is moved downwards, causing the toothed blocks on the valve body to re-engage into the toothed grooves of the rotating disk. The cooperation between the toothed blocks and the toothed grooves restricts the circumferential rotation of the rotating disk, thereby fixing the position of the rotating shaft and the valve core, preventing the valve core from shifting due to changes in pipeline water pressure. Because the cooperation between the rotating disk and the toothed blocks on the valve body can circumferentially lock the rotating shaft after the valve core adjustment is completed, it prevents the disturbance to the valve core caused by the main water supply system pressure fluctuations transmitted to the bypass. Therefore, the valve core will not rotate slightly due to water pressure fluctuations, and the operating mechanism will not generate high-frequency vibrations, effectively avoiding noise and leakage risks caused by high-frequency vibrations of the operating mechanism.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.

[0019] This utility model discloses an operating valve for a water supply system, which includes a valve body 1 and a valve core. The valve core is connected to an operating mechanism. The operating mechanism includes a rotating shaft 2 and a fixed seat 3. A rotating disk 4 that can only move up and down relative to the fixed seat 3 is installed below the fixed seat 3. The outer periphery of the rotating disk 4 has toothed grooves arranged circumferentially along its center position. A toothed block 5 is fixed on one side of the valve body 1.

[0020] In this embodiment, as Figure 1As shown, the valve body 1 is a hollow cavity structure. The valve core is installed inside the cavity of the valve body 1 to control the flow of water within the valve body 1. The operating structure is connected to the valve core; operating the operating structure can drive the valve core to move, thereby controlling the flow of water. The rotating shaft 2 is arranged vertically, and its lower end is connected to the valve core. The fixed seat 3 is an annular block structure, fixedly fitted around the outer circumference of the rotating shaft 2. The rotating disk 4 is located directly below the fixed seat 3, with a through hole at its center for the rotating shaft 2 to pass through. The rotating disk 4 can move up and down relative to the fixed seat 3 along the axis of the rotating shaft 2. Multiple toothed grooves are evenly distributed on the outer circumferential wall of the rotating disk 4, and the shape and size of the toothed grooves are adapted to the toothed block 5. The toothed block 5 has a toothed structure and is fixedly installed on one side of the upper end face of the valve body 1. When the rotating disk 4 moves downward to a specific position, the toothed block 5 can be precisely inserted into the tooth groove of the rotating disk 4, thus limiting the circumferential rotation of the rotating disk 4. When the rotating disk 4 moves upward, the toothed block 5 disengages from the tooth groove, releasing the circumferential limitation on the rotating disk 4.

[0021] In actual use, when it is necessary to adjust the valve core state to control water flow, first move the rotating disk 4 upwards, causing the toothed grooves on the outer circumference of the rotating disk 4 to disengage from the toothed blocks 5 on the valve body 1, thus releasing the circumferential restriction of the rotating disk 4 by the toothed blocks 5. Then rotate the shaft 2, which drives the valve core to rotate synchronously, realizing the opening, closing, or opening degree adjustment of the valve core. After the valve core is adjusted to the target state, move the rotating disk 4 downwards, causing the toothed blocks 5 to engage in the toothed grooves of the rotating disk 4. The engagement between the toothed blocks 5 and the toothed grooves restricts the circumferential rotation of the rotating disk 4, thereby restricting the rotation of the shaft 2 and keeping the valve core in the current adjusted state.

[0022] In the above structure, a movable rotating disk 4 engages with a toothed block 5 fixed on the valve body 1 to limit the rotation of the rotating shaft 2. When the valve core needs adjustment, the limit is released to allow the rotating shaft 2 to rotate flexibly. After adjustment, the position of the rotating shaft 2 is fixed by the limit, preventing the valve core from vibrating due to water pressure fluctuations. This effectively solves the problem in the prior art where water pressure fluctuations cause vibration of the bypass water valve core, generate noise, and affect service life, thus improving the stability and durability of the operating valve.

[0023] In the specific structure of the rotating disk 4 and the toothed block 5, the rotating disk 4 includes a toothed disk 401 and an annular ring 402, and the bottom of the fixed base 3 is provided with an annular groove 301, which can accommodate the annular ring 402 of the rotating disk 4. Figure 1 , Figure 2 , Figure 3As shown, the outer peripheral wall of the toothed disk 401 is machined with toothed grooves that mate with the toothed block 5. The circumferential positioning of the rotating disk 4 can be achieved through the engagement of the toothed grooves and the toothed block. The annular ring 402 is a metal ring coaxial with the toothed disk 401 and is fixed at the center of the upper end face of the toothed disk 401. The annular ring 402 and the toothed disk 401 are together sleeved on the rotating shaft 2. The lower end face of the fixed seat 3 is provided with an annular groove 301. The inner diameter and outer diameter of the annular groove 301 are adapted to the outer diameter and inner diameter of the annular ring 402, respectively. The annular ring 402 can be completely inserted into the annular groove 301 and slide up and down along the groove wall to guide the vertical movement of the rotating disk 4. The inner wall of the annular groove 301 is symmetrically provided with strip-shaped grooves 302 in the vertical direction. The length of the grooves 302 is adapted to the height of the annular ring 402. The outer wall of the annular ring 402 is provided with strip-shaped protrusions 403 corresponding to the position of the grooves 302. The size of the protrusions 403 matches the grooves 302. The protrusions 403 can slide in the vertical direction in the grooves 302 and cannot rotate around the annular groove 301, thereby restricting the overall circumferential rotation of the rotating disk 4.

[0024] In the above structure, the engagement between the annular ring 402 and the annular groove 301 of the fixed base 3 can provide guidance for the up-and-down movement of the rotating disk 4. At the same time, the engagement between the groove 302 and the protrusion 403 can restrict the rotation between the rotating disk 4 and the toothed block 5.

[0025] like Figure 1 , Figure 3 , Figure 4 As shown, two vertical support rods 6 are fixed to the upper surface of the toothed disk 401. Both vertical support rods 6 are cylindrical rods, symmetrically fixed on both sides of the upper surface of the toothed disk 401 along the vertical direction, and located outside the annular ring 402. The upper ends of the two vertical support rods 6 are connected by a horizontal limiting rod 7. The horizontal limiting rod 7 is horizontally positioned, with its two ends fixedly connected to the tops of the two vertical support rods 6 respectively. The middle position of the horizontal limiting rod 7 spans directly above the rotating shaft 2. The upper surface of the rotating shaft 2 is a planar structure, with a pin 9 fixed at one edge. The pin 9 is vertically positioned. A limiting bolt 8 is rotatably installed on the upper surface of the rotating shaft 2. The limiting bolt 8 is a long, block-shaped structure, with one end rotatably connected to the upper surface of the rotating shaft 2 via the pin 9. The limiting bolt 8 can rotate around the pin 9 on the horizontal plane. When the limiting bolt 8 rotates to the position where it intersects with the transverse limiting rod 7, the limiting bolt 8 can span across the transverse limiting rod 7, thus limiting the transverse limiting rod 7 upwards. When the limiting bolt 8 rotates to the position where it is offset from the transverse limiting rod 7, the limitation on the transverse limiting rod 7 is released. A magnet 10 is fixed to the bottom of the other end of the limiting bolt 8. The magnet 10 is a block-shaped permanent magnet, fixed to the lower surface of the end of the limiting bolt 8 away from the pin 9. The corresponding position on the upper end face of the rotating shaft 2 is made of magnetic metal. When the limiting bolt 8 rotates to span across the transverse limiting rod 7, the magnet 10 just contacts and attracts the metal part of the upper end face of the rotating shaft 2.

[0026] In the above structure, the cooperation of the vertical support rod 6 and the horizontal limiting rod 7 provides the operator with a convenient point of force application. The operator can move the rotating disk 4 up and down by moving the horizontal limiting rod 7 upwards or downwards, without directly contacting the rotating disk 4, making the operation more convenient and labor-saving. Utilizing the cooperation of the limiting bolt 8 and the horizontal limiting rod 7, after the rotating disk 4 moves downwards until the toothed block 5 engages in the toothed groove, the limiting bolt 8 can be rotated to span the horizontal limiting rod 7, restricting the upward movement of the horizontal limiting rod 7, thereby fixing the position of the rotating disk 4 and preventing the toothed block 5 from disengaging from the toothed groove of the rotating disk 4. Simultaneously, the magnet 10 ensures the stability of the limiting bolt 8 in the limited position, preventing it from rotating on its own and releasing the limit, further improving the reliability of the structure.

[0027] Specifically, such as Figure 3 , Figure 5 As shown, a spring 11 is installed in the annular groove 301 of the fixed base 3. The spring 11 is a cylindrical helical spring, and multiple springs are provided. The spring 11 is installed in the annular groove 301 of the fixed base 3 and fixed to the upper end face of the annular ring 402. The upper end of the spring 11 is fixedly connected to the center of the top wall of the annular groove 301, and the lower end is fixedly connected to the upper end face of the annular ring 402. When the toothed block 5 is not engaged in the toothed groove of the rotating disk 4, the spring 11 is in a naturally extended state or a slightly stretched state; when the operator moves the rotating disk 4 downwards, causing the annular ring 402 to move downwards, the spring 11 is gradually stretched, generating an upward pulling force on the rotating disk 4. When the rotating disk 4 moves to the position where the toothed block 5 is engaged in the tooth groove, the limiting bolt 8 is rotated so that it spans above the transverse limiting rod 7. At this time, the spring 11 is in a stretched state, and the upward force it generates causes the rotating disk 4 to tend to move upward. However, due to the limiting effect of the limiting bolt 8 on the transverse limiting rod 7, the rotating disk 4 cannot move upward, thus keeping the toothed block 5 stably engaged with the tooth groove. When it is necessary to release the limit, the limiting bolt 8 is rotated so that it is displaced from the transverse limiting rod 7. The tension of the spring 11 causes the rotating disk 4 to move upward automatically, causing the toothed block 5 to disengage from the tooth groove.

[0028] In the above structure, the spring 11 enables the automatic reset function of the rotating disk 4. When the limiting bolt 8 is released, the spring 11 can drive the rotating disk 4 to move upward automatically, without the need for the operator to manually move the horizontal limiting rod 7 upward. At the same time, in the limiting state, the tension of the spring 11 ensures that the rotating disk 4 always has an upward tendency. Combined with the limiting effect of the limiting bolt 8, this effectively prevents the tooth block 5 from disengaging from the tooth groove due to vibration or slight external force causing the rotating disk 4 to move upward.

[0029] In this embodiment, as Figure 1 , Figure 5As shown, a telescopic rod 12 is vertically connected between the top wall of the annular groove 301 inside the fixed base 3 and the upper end face of the annular ring 402. The number of telescopic rods 12 is the same as the number of springs 11, and they are arranged in a one-to-one correspondence. The telescopic rod 12 is installed in the annular groove 301 of the fixed base 3, with its upper end fixedly connected to the top wall of the annular groove 301 and its lower end fixedly connected to the upper end face of the annular ring 402. The inner rod body and the outer tube body of the telescopic rod 12 are both cylindrical tubular structures. The inner diameter of the outer tube body is adapted to the outer diameter of the inner rod body. The inner rod body can slide vertically inside the outer tube body, thereby realizing the telescopic function of the telescopic rod 12. The spring 11 is sleeved on the outer circumference of the telescopic rod 12. The inner diameter of the spring 11 is slightly larger than the outer diameter of the telescopic rod 12 to ensure that the spring 11 will not interfere with the telescopic rod 12 when it extends or retracts. The telescopic rod can further ensure the degree of freedom between the rotating disk 4 and the fixed base 3, so that the rotating disk 4 can only move up and down relative to the fixed base 3.

[0030] In addition, a ring-shaped handle 13 is connected to the upper end of the rotating shaft 2, and the inner ring of the handle 13 is fixedly connected to the outer periphery of the upper end of the rotating shaft 2 through a connecting rod 14. Figure 1 , Figure 3 As shown, the handle 13 is a circular ring structure with a diameter larger than that of the rotating shaft 2, making it easy for the operator to grip. The connecting rod 14 is a cylindrical rod, with 3-4 rods evenly distributed circumferentially between the inner ring of the handle 13 and the outer ring of the rotating shaft 2. One end of the connecting rod 14 is fixedly connected to the inner ring of the handle 13, and the other end is fixedly connected to the outer peripheral wall of the upper end of the rotating shaft 2. The connecting rod 14 ensures a secure connection between the handle 13 and the rotating shaft 2. When the operator rotates the handle 13, the rotating shaft 2 rotates synchronously via the connecting rod 14, making operation less strenuous compared to directly rotating the rotating shaft 2.

[0031] In actual operation, the device of this invention exists in two states: The first state is the valve core locked state. In this state, the toothed block 5 is engaged in the toothed groove of the rotating disk 4, and the spring 11 is in a stretched state. The spring 11 exerts an upward traction force on the toothed disk 401 of the rotating disk 4. However, since the limiting bolt 8 spans above the horizontal limiting rod 7, it restricts the upward movement of the horizontal limiting rod 7. In turn, the vertical support rod 6 restricts the upward movement of the toothed disk 401, so that the toothed block 5 and the toothed groove remain engaged. The rotating shaft 2 cannot rotate because the rotating disk 4 is limited. The valve core is fixed in the current working state. Even if there is water pressure fluctuation in the water supply pipeline, the valve core will not vibrate with the fluctuation, effectively avoiding pipeline noise and protecting the valve core from vibration damage.

[0032] The second type is the valve core adjustment state. When it is necessary to change the valve core state, such as opening, closing, or adjusting the flow rate, first rotate the limiting bolt 8 around the pin 9, so that the limiting bolt 8 moves away from above the transverse limiting rod 7, releasing the upward movement restriction on the transverse limiting rod 7. At this time, the toothed disc 401 moves upward under the upward traction force of the spring 11, driving the rotating disc 4 to move upward as a whole. The toothed grooves on the outer circumference of the rotating disc 4 separate from the toothed blocks 5, and the circumferential restriction of the rotating shaft 2 is released. The operator holds the handle 13 and rotates it, driving the rotating shaft 2 to rotate (fixed seat 3, rotating disc 4, ...). The vertical support rod 6 and the horizontal limiting rod 7 rotate synchronously. The rotating shaft 2 drives the valve core to rotate until the valve core reaches the target state. Then, the horizontal limiting rod 7 is pressed down, and the toothed disc 401 moves downward against the traction force of the spring 11 through the vertical support rod 6. This causes the tooth groove of the rotating disc 4 to align and engage with the toothed block 5 again. The spring 11 is stretched again. Finally, the limiting bolt 8 is rotated so that it crosses over the horizontal limiting rod 7 again. The position of the limiting bolt 8 is fixed by the magnet 10. The device returns to the valve core locked state, completing one valve core adjustment.
