Description

Technical Field

[0001] This invention relates to the field of water valve technology, and more specifically, to a manual actuator for a water valve and an actuator monitoring device. Background Technology

[0002] A water valve is a control element installed in a pipeline to control water flow, cut off water flow, regulate water pressure and flow, and change the direction of water flow. Water valves adjust the size of the water flow or stop the water flow by opening and closing the valve. They are widely used in various industrial equipment (gate valves, globe valves, or discharge valves, etc.), buildings, home decoration, and other related fields. By adjusting the degree of valve opening, water valves can precisely control the water flow. They are suitable for occasions that require precise control of water flow, such as laboratory water use. During pipeline inspection or maintenance, it is necessary to close the valves on the pipeline to cut off the water flow and ensure maintenance safety.

[0003] Among them, the patent with announcement number CN104373608A discloses an airtight and watertight fireproof windbreak, including a windbreak body, a rotating shaft and a valve plate. The two sides of the windbreak body are flange joints. A lower mechanism seat is connected to the top opening of the windbreak body. An upper mechanism seat is welded to the upper surface of the lower mechanism seat. The bottom end of the rotating shaft passes through the upper and lower mechanism seats from the top of the windbreak body and extends into the shaft hole at the bottom of the inner cavity of the windbreak body. A ball bearing is provided between the bottom surface of the shaft hole and the end face of the rotating shaft. A valve plate is provided inside the windbreak body. The valve plate is fixedly connected to the rotating shaft. A temperature sensor is also provided inside the windbreak body. The temperature sensor is sealed and installed on the upper mechanism seat and extends into the windbreak body through the lower mechanism seat. A manual actuator is provided above the upper mechanism seat. The manual actuator is connected to the rotating shaft. The temperature sensor is connected to the manual actuator.

[0004] In use, this structure is welded to the gate body via a lower mechanism seat, and a sealing ring is installed between the upper and lower mechanism seats to ensure the overall sealing of the gate body. The rotating shaft and the temperature sensor are respectively sealed to the upper mechanism seat via bearings with sealing rings and temperature-sensing sealing sleeves to ensure airtightness and watertightness. The temperature sensor is installed on the upper mechanism seat by a temperature-sensing sealing sleeve, which is fixed to the upper mechanism seat by screws. This not only serves a sealing function but also facilitates the replacement of the temperature-sensing fin on the temperature sensor. However, this structure is not easy to quickly adjust and switch during use, and it is not easy to alarm according to the situation, making the device inconvenient to use. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a manual water valve actuator and an actuator monitoring device, which aims to solve the problems mentioned in the background art.

[0006] The present invention provides the following technical solution: a manual actuator for a water valve, comprising a reinforced valve body, wherein a connecting component is provided on the reinforced valve body.

[0007] The connecting assembly includes a connector located at the bottom of the reinforced valve body. The reinforced valve body and the connector are connected by a flange. An inner liner is fixedly installed inside the connector. A through hole is opened through the inner liner. A sealing element is provided on the top of the inner liner. A flow meter for sealing is embedded inside the sealing element.

[0008] The flow meter has an inner liner tube in the middle, and a threaded cylinder is fixedly installed at the top end of the inner liner tube. The threaded cylinder passes through the reinforced valve body and extends to the top of the reinforced valve body.

[0009] The top of the reinforced valve body is rotatably connected to a turntable. A first reinforcing connecting tray is positioned on top of the turntable. A limiting cavity is formed through the middle of the first reinforcing connecting tray. A second reinforcing connecting tray is positioned on top of the first reinforcing connecting tray, and a third reinforcing connecting tray is positioned on top of the second reinforcing connecting tray. The first, second, and third reinforcing connecting trays are stacked, and each of them is fitted onto the outside of a threaded cylinder. A spring positioning cylinder is fixedly mounted on the top of the third reinforcing connecting tray. A limiting pin is inserted for limiting the position. The limiting pin is slidably connected to the spring positioning cylinder. The upper surface of the second reinforcing connecting tray body has several limiting slots. One end of the limiting pin passes through the spring positioning cylinder and the third reinforcing connecting tray body and extends into the limiting slot. A spring is sleeved on the outside of the limiting pin body. A handle is inserted into the outside of the inner liner plate. A connecting pipe is fixedly installed at the bottom end of the first reinforcing connecting tray body. The connecting pipe is located at the top of the threaded cylinder. An internal threaded nest is threaded to the outside of the threaded cylinder. The internal threaded nest is embedded in the middle of the first reinforcing connecting tray body. Both the connecting pipe and the threaded cylinder are hollow and are connected to each other.

[0010] As can be seen, in the above technical solution, by pulling the limiting pin, the spring on the limiting pin is compressed. Then, by rotating the handle, the handle drives the spring positioning cylinder, the third reinforcing connecting tray, and the limiting pin to rotate. This allows the limiting pin to pass through the third reinforcing connecting tray and the spring positioning cylinder and extend into the limiting slot. By rotating the turntable, the first reinforcing connecting tray and the inner thread nest are rotated. This causes the threaded cylinder and the inner liner tube to move due to the traction force of the first reinforcing connecting tray, the turntable, and the inner thread nest rotating. When the inner liner tube moves, it causes the flow meter and the seal to move, and the through hole loses its seal. This allows the medium to pass through the barrier of the inner liner plate and then be discharged through the through hole when it is transported through the connector, thus realizing the function of flow control.

[0011] An actuator monitoring device includes a temperature sensor and the aforementioned manual water valve actuator. The temperature sensor is located at the bottom of the inner cavity of the reinforced valve body and is wrapped around the outside of the inner liner tube. An alarm is embedded in the middle of the third reinforced connecting tray body, and a controller is embedded in the middle of the alarm. A pad is provided at the bottom of the controller, and the pad is located between the second and third reinforced connecting tray bodies. A locking block is fixedly provided on the outside of the controller, and the locking block engages with the third reinforced connecting tray body.

[0012] As can be seen, in the above technical solution, through the setting of the inner liner and temperature sensor, the conveyed medium is flow-sensing through the flow meter, and the temperature of the medium can be transmitted to the temperature sensor through the inner liner. The temperature sensor senses the temperature transmitted by the inner liner, thereby realizing the function of monitoring the temperature and flow of the conveyed medium. At the same time, the controller analyzes and processes the data. When the flow or temperature of the conveyed medium reaches the preset value, the alarm is triggered to facilitate the operation and control by the staff.

[0013] The technical effects and advantages of this invention are as follows:

[0014] 1. The present invention rotates the first reinforcing connecting tray body and the inner thread nesting, thereby causing the threaded cylinder and the inner liner tube to move due to the traction force of the first reinforcing connecting tray body, the turntable and the inner thread nesting rotating. When the inner liner tube moves, it will cause the flow meter and the sealing element to move, and the through hole will lose its seal, so that the medium can be discharged through the through hole after passing through the partition of the inner liner plate when it is transported through the connector, thus realizing the function of flow control.

[0015] 2. The present invention compresses the spring on the limiting pin by pulling the limiting pin, and then rotates the handle to drive the spring positioning cylinder, the third reinforcing connecting tray and the limiting pin to rotate, so that the limiting pin can pass through the third reinforcing connecting tray and the spring positioning cylinder and extend into the limiting slot, so as to facilitate the linkage of various structures and improve the convenience of the device in use.

[0016] 3. With the setting of the inner liner and temperature sensor, the medium being transported is flow-sensing through the flow meter, and the temperature of the medium can be transmitted to the temperature sensor through the inner liner. The temperature sensor senses the temperature transmitted by the inner liner, thereby realizing the function of monitoring the temperature and flow of the transported medium.

[0017] 4. The present invention analyzes and processes the data through a controller. When the flow rate or temperature of the transported medium reaches a preset value, the alarm will be triggered to facilitate the operation and control by the staff, thereby realizing the function of synchronous monitoring of the flow rate and temperature during the transport of the medium.

[0018] In summary, through the coordinated use of various structures, the through hole loses its seal, allowing the medium to pass through the inner liner plate and discharge through the through hole when transported via the connector, thus achieving flow control. The limit pin can penetrate the third reinforced connecting tray and the spring positioning cylinder and extend into the limit slot, facilitating the linkage of various structures and improving the convenience of use. The transported medium is flow-sensing via a flow meter, while the temperature of the medium is transmitted to a temperature sensor via the inner liner. The temperature sensor senses the temperature transmitted by the inner liner, thereby achieving the function of monitoring the temperature and flow of the transported medium. After analysis and processing by the controller, when the flow rate or temperature of the transported medium reaches the preset value, the alarm is triggered, allowing operators to make adjustments and achieving the function of synchronous monitoring of flow rate and temperature during medium transport.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] As attached Figure 1 - Figure 8 The manual actuator for a water valve shown in the figure strengthens the connecting components on the valve body 1. The through-hole 4 is sealed, allowing the medium to pass through the inner liner 3 and then discharge through the through-hole 4 when transported via the connector 2, thus achieving flow control. The limiting pin 15 can penetrate the third reinforced connecting tray 13 and the spring positioning cylinder 14 and extend into the limiting slot 24, facilitating linkage between various structures and improving the ease of use. The transported medium is flow-sensing via the flow meter 6, while the temperature of the medium is transmitted to the temperature sensor 19 via the inner liner 7. The temperature sensor 19 senses the temperature transmitted by the inner liner 7, thereby achieving the function of monitoring the temperature and flow of the transported medium. The controller 21 analyzes and processes the data. When the flow or temperature of the transported medium reaches a preset value, the alarm 20 is triggered, allowing for operator adjustment. This achieves the function of synchronous monitoring of flow and temperature during medium transport. The specific structural configuration of the components is as follows.

[0031] The connection assembly includes a connector 2 located at the bottom of the reinforced valve body 1. The reinforced valve body 1 and the connector 2 are connected by a flange. An inner liner 3 is fixedly installed inside the connector 2. A through hole 4 is opened through the inner liner 3. A sealing element 5 is provided on the top of the inner liner 3. A flow meter 6 for sealing is embedded inside the sealing element 5.

[0032] The flow meter 6 has an inner liner 7 in the middle, and a threaded cylinder 8 is fixedly installed at the top of the inner liner 7. The threaded cylinder 8 passes through the reinforcing valve body 1 and extends to the top of the reinforcing valve body 1.

[0033] A turntable 9 is rotatably connected to the top of the reinforced valve body 1. A first reinforced connecting tray 10 is mounted on the top of the turntable 9. A limiting cavity 11 is formed through the middle of the first reinforced connecting tray 10. A second reinforced connecting tray 12 is mounted on the top of the first reinforced connecting tray 10. A third reinforced connecting tray 13 is mounted on the top of the second reinforced connecting tray 12. The first reinforced connecting tray 10, the second reinforced connecting tray 12, and the third reinforced connecting tray 13 are stacked and all are fitted onto the outside of the threaded cylinder 8. A spring positioning cylinder 14 is fixedly mounted on the top of the third reinforced connecting tray 13. A spring positioning cylinder 14 is inserted into the spring positioning cylinder 14. The limiting pin 15 is used for limiting the position. The limiting pin 15 is slidably connected to the spring positioning cylinder 14. The upper surface of the second reinforcing connecting tray 12 is provided with several limiting slots 24. One end of the limiting pin 15 passes through the spring positioning cylinder 14 and the third reinforcing connecting tray 13 and extends into the limiting slot 24. A spring is sleeved on the outside of the limiting pin 15. A handle 16 is inserted into the outside of the inner liner 3. A connecting pipe 17 is fixedly provided at the bottom end of the first reinforcing connecting tray 10. The connecting pipe 17 is located at the top of the threaded cylinder 8. An inner threaded nest 18 is threadedly connected to the outside of the threaded cylinder 8. The inner threaded nest 18 is embedded in the middle of the first reinforcing connecting tray 10. Both the connecting pipe 17 and the threaded cylinder 8 are hollow and are connected to each other.

[0034] An actuator monitoring device includes a temperature sensor 19 and the aforementioned manual water valve actuator. The temperature sensor 19 is located at the bottom of the inner cavity of the reinforced valve body 1 and is wrapped around the outside of the inner liner tube 7. An alarm 20 is embedded in the middle of the third reinforced connecting tray body 13, and a controller 21 is embedded in the middle of the alarm 20. A pad 22 is provided at the bottom of the controller 21 and is located between the second reinforced connecting tray body 12 and the third reinforced connecting tray body 13. A locking block 23 is fixedly provided on the outside of the controller 21 and engages with the third reinforced connecting tray body 13.

[0035] When using the device according to the above structure, the operator installs it at the designated location and installs the water pipe at the end of the connector 2. When adjusting, by pulling the limiting pin 15, the spring on the limiting pin 15 is compressed. Then, by rotating the handle 16, the handle 16 drives the spring positioning cylinder 14, the third reinforcing connecting tray 13 and the limiting pin 15 to rotate, so that the limiting pin 15 can pass through the third reinforcing connecting tray 13 and the spring positioning cylinder 14 and extend into the limiting slot 24.

[0036] The rotating turntable 9 drives the first reinforcing connecting tray 10 and the inner threaded nest 18 to rotate, which in turn causes the threaded cylinder 8 and the inner liner tube 7 to move due to the traction force of the first reinforcing connecting tray 10, the turntable 9 and the inner threaded nest 18 rotating. When the inner liner tube 7 moves, it will drive the flow meter 6 and the sealing element 5 to move, and the through hole 4 will lose its seal, so that the medium can be discharged through the through hole 4 after passing through the partition of the inner liner plate 3 when it is transported through the connector 2, thus realizing the function of flow control.

[0037] Furthermore, through the setting of the inner liner 7 and the temperature sensor 19, the conveyed medium is flow-sensing through the flow meter 6, and the temperature of the medium can be transmitted to the temperature sensor 19 through the inner liner 7. The temperature sensor 19 senses the temperature transmitted by the inner liner 7, thereby realizing the function of monitoring the temperature and flow of the conveyed medium. At the same time, the controller 21 analyzes and processes the data. When the flow or temperature of the conveyed medium reaches the preset value, the alarm 20 senses and alarms, so that the staff can make adjustments.

[0038] Unlike existing technologies, this application discloses a manual actuator for a water valve and an actuator monitoring device. The through-hole 4 is unsealed, allowing the medium to pass through the inner liner 3 and then discharge through the through-hole 4, thus achieving flow control. The limiting pin 15 can penetrate the third reinforcing connecting tray 13 and the spring positioning cylinder 14 and extend into the limiting slot 24, facilitating the linkage of various structures and improving the ease of use. The transported medium is flow-sensing via the flow meter 6, while the medium's temperature is transmitted to the temperature sensor 19 via the inner liner 7. The temperature sensor 19 senses the temperature transmitted by the inner liner 7, thereby achieving the function of monitoring the temperature and flow of the transported medium. The controller 21 analyzes and processes the data. When the flow rate or temperature of the transported medium reaches a preset value, the alarm 20 triggers an alarm, allowing for operator intervention and achieving synchronous monitoring of the flow rate and temperature during medium transport.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
