[0001] The embodiments of the present invention relate to the technical field of stop valves, and in particular, to a stop valve system and a control method. Background Art

[0002] Ball stop valves are usually used on hydraulic pipelines for fully mechanized mining in underground coal mines. However, the existing technology for controlling ball stop valves is relatively simple. A handle or motor is used to adjust the valve opening, and the start and stop of the motor are also manually controlled. The valve opening adjustment process is not intelligent enough. Moreover, due to the working environment, the load pressure often changes during underground work. The existing motor output cannot be adjusted automatically, and the valve opening cannot be adjusted in time, affecting the work process. Summary of the Invention

[0005] In some embodiments, the stop valve includes a valve stem, a valve body and a steel ball, a valve body channel is set in the valve body, the steel ball is set in the valve body and a medium channel is set to cooperate with the valve body channel, one end of the valve stem is connected to the steel ball, and the other end thereof passes through the valve body and is connected to the output shaft of the motor, and the controller is used to control the motor based on the operating information to drive the rotation of the steel ball through the valve stem to adjust the opening of the stop valve.

[0006] In some embodiments, a reducer is further included, and the output shaft of the motor is connected to the valve stem of the stop valve through the reducer; a temperature sensor is provided on the motor, and the temperature sensor is electrically connected to the controller.

[0007] In some embodiments, a manual device is further included, and the manual device is connected to the output shaft of the motor through a transmission member.

[0008] In some embodiments, the transmission member includes a first bevel gear and a second bevel gear meshing with each other, the first bevel gear is connected to the output shaft of the motor, and the second bevel gear is connected to the manual device.

[0009] Another aspect of the present disclosure provides a control method for a stop valve system, which is used in any of the above stop valve systems, comprising:

[0010] controlling the motor to start in response to a stop valve opening adjustment instruction;

[0011] updating the operation information of the motor based on the operation information of the motor collected by the encoder;

[0012] The motor is controlled to operate according to the updated operation information to adjust the opening of the stop valve.

[0013] In some embodiments, updating the operation information of the motor based on the operation information of the motor acquired by an encoder includes:

[0014] Acquiring position information of the motor collected by the encoder;

[0015] The current opening value of the stop valve is obtained based on the position information. When the current opening value is greater than or equal to a set opening threshold, the motor is controlled to stop running. When the current opening value is not less than the set opening threshold, the motor is controlled to continue running.

[0016] In some embodiments, after controlling the motor to continue to operate, the method further includes:

When the speed data is less than the set speed value, or even when the speed is equal to zero, it will affect the opening adjustment of the stop valve, thereby affecting the entire work process. This embodiment sets a controller and an encoder. When the controller determines that the opening of the stop valve 300 does not meet the set stop valve opening requirement and the speed data is less than the set speed value, the controller increases the output current to the motor and increases the motor torque, so that the stop valve can adjust the opening size, thereby improving the work efficiency of mine mining. The present disclosure can also automatically monitor the temperature, current and voltage of the motor to ensure the safety of the entire stop valve system.

[0041] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," each of which may refer to one or more of the same or different embodiments according to the present invention.

[0042] like Figure 1 、 Figure 2 and Figure 3 As shown, the first embodiment of the present disclosure provides a stop valve system, including a motor 100, a controller 800, a stop valve 300 and an encoder 900, wherein the controller 800 and the motor 100 are electrically connected to the encoder 900 respectively, and the controller 800 is also electrically connected to the motor 100, and the output shaft of the motor 100 is connected to the stop valve 300; the encoder 900 can collect the operating conditions of the motor 100 and transmit the collected motor operating information to the controller 800, and the controller 800 judges the operating information, controls the output data of the motor 100, and realizes the adjustment of the opening size of the stop valve 300.

[0043] Specifically, in this embodiment, the encoder 900 can collect the operating status of the motor 100 and transmit the collected motor operating information to the controller 800. The controller 800 judges the operating information and adjusts the operating data of the motor 100 to adjust the opening size of the stop valve 300, specifically including:

[0044] The encoder 900 can monitor the position information of the motor 100 and transmit it to the controller 800. The controller 800 determines the opening of the stop valve 300 based on the position information. If the set stop valve opening requirement is met, the controller 800 outputs a stop instruction to the motor 100. If the set stop valve opening requirement is not met, the controller 800 outputs a start instruction to the motor 100.

[0045] More specifically, in this embodiment, the encoder 900 can monitor the position information of the motor 100 and transmit it to the controller 800. The controller 800 determines the opening of the stop valve 300 based on the position information. If the set stop valve opening requirement is met, the controller 800 outputs a stop instruction to the motor 100. If the set stop valve opening requirement is not met, the controller 800 outputs a start instruction to the motor 100. The process also includes:

[0046] The encoder 900 can monitor the speed data of the motor 100 and transmit it to the controller 800. When the controller 800 determines that the opening of the stop valve 300 does not meet the set stop valve opening requirement, the controller 800 adjusts the operation data of the motor 100 according to the speed data. When the speed data is greater than the set speed value, the controller 800 controls the motor 100 to continue operating according to the speed data. When the speed data is less than the set speed value, the controller 800 controls the motor 100 to increase the torque output. More specifically, the controller 800 increases the torque of the motor 100 by increasing the output current to the motor 100.

[0047] In this embodiment, the output shaft of the motor 100 is connected to the reducer 200, and the output shaft of the reducer 200 is connected to the shut-off valve 300. When the speed data is less than the set speed value, the reducer 200 reduces speed and increases torque and opens.

[0048] During the mine production process, the pressure of the load 1100 will often change. When the pressure of the load 1100 increases, it will cause the rotational resistance of the motor 100 and the speed to drop. When the speed data is less than the set speed value, or even when the speed is equal to zero, it will affect the opening adjustment of the stop valve 300, thereby affecting the entire working process. In this embodiment, by setting a controller 800 and an encoder 900, when the controller 800 determines that the opening of the stop valve 300 does not meet the set stop valve opening requirement and the speed data is less than the set speed value, the controller 800 increases the output current to the motor 100, increases the torque of the motor 100, and enables the stop valve 300 to adjust the opening size, thereby improving the working efficiency of mine mining.

[0049] In this embodiment, the stop valve system also includes a host computer 1000, which is electrically connected to the controller 800. People skilled in the art can set the opening requirement of the stop valve 300 through the host computer 1000, and then the host computer 1000 transmits the opening requirement of the stop valve 300 to the controller 800. The controller 800 adjusts the operating data of the motor according to the opening requirement of the stop valve 300, thereby realizing the opening adjustment of the stop valve 300.

[0050] In this embodiment, the encoder 900 can monitor the current data of the motor 100 and then transmit the current data to the controller 800. The controller 800 judges the motor temperature based on the current data. When the temperature exceeds the set temperature value, the controller 800 outputs a stop instruction to the motor 100 to avoid overheating and damage to the equipment.

[0051] In this embodiment, the encoder 900 transmits the current data to the controller 800. When the difference between the minimum current data and the maximum current data within a set time interval is greater than a set threshold, it is judged as a current mutation, and the motor 100 is stalled. The controller 800 sends a stop signal or a reverse signal to the motor 100, and the controller 800 sends a fault warning signal to the host computer 1000 to remind the staff to take timely action.

[0052] In some embodiments, a temperature sensor is provided on the motor 100, and the temperature sensor transmits the collected temperature data to the controller 800. The controller 800 judges the motor temperature based on the temperature data. When the temperature exceeds the set temperature value, the controller 800 outputs an instruction to stop the operation to the motor 100 to avoid overheating and damage to the equipment.

[0053] In some embodiments, the encoder 900 can monitor the voltage data and current data of the motor 100, and then transmit the voltage data and the current data to the controller 800. The controller 800 respectively determines whether the voltage data and the current data exceed the set voltage threshold and the set current threshold. When the voltage data and / or the current data exceed the set voltage threshold and the set current threshold, the controller 800 cuts off the power supply to protect the device.

[0054] The encoder 900 is a single-turn encoder that can accurately control the opening of the stop valve (0-100% opening adjustment). The single-turn encoder is a sensor for measuring the rotational angle position, and its measurement range is limited to 0° to 360° (single turn). The resolution is 12-24 bits (such as 24 bits corresponding to 0.00002° per turn), which is suitable for precision control scenarios. There is no need to reset to zero after power failure, and the current position is read upon power-on. The uniqueness of the encoding ensures reliability. It is smaller in size and suitable for space-constrained applications (such as embedded systems). Supports digital interfaces (SSI, SPI, BiSS), analog output (voltage / current) or PWM signals. Industrial-grade protection (IP65-IP68), high temperature resistance (-40°C to +85°C), vibration resistance and electromagnetic interference resistance.

[0055] The disclosed embodiment can realize intelligent control of the stop valve, automatically adjust the valve opening size according to the set stop valve opening requirement, output different speeds and torques according to different working conditions, improve work efficiency, and speed up the work process compared with the existing technology; it can also automatically monitor the temperature, current and voltage of the motor to ensure the safety of the entire stop valve system.

[0056] In some embodiments, as Figure 2 and Figure 3 As shown, the stop valve 300 includes a valve stem 301, a valve body 302 and a steel ball 303. The valve stem 301 is arranged on the valve body 302 and is rotatably connected to the valve body 302. The valve stem 301 is used to receive external torque. A valve body channel is provided in the valve body 302. Here, the penetration direction of the valve body channel is perpendicular to the connection direction between the motor 100 and the stop valve 300. The steel ball 303 is arranged inside the valve body 302, wherein one end of the valve stem 301 is connected to the output shaft of the motor 100, and the other end thereof is connected to the steel ball 303. The rotation of the valve stem 301 drives the rotation of the steel ball 303. Here, the valve body channel is opened or closed by the rotation of the steel ball 303.

[0057] Furthermore, the valve body 302 adopts a split structure, comprising a first valve body 3021 and a second valve body 3022, which are connected to form an integral structure. A valve seat 304 is disposed within the valve body 302. The valve seat 304 comprises a first valve seat 3041 and a second valve seat 3042. The first valve seat 3041 is mounted within the first valve body 3021, and the second valve seat 3042 is mounted within the second valve body 3022. The steel ball 303 is disposed between the first valve seat 3041 and the second valve seat 3042. Furthermore, a sealing ring 600 is provided at the connection between the first valve body 3021 and the second valve body 3022 to prevent medium leakage.

[0058] Furthermore, in this embodiment, a first mounting hole for the valve stem 301 to pass through is opened on the first valve body 3021, the first mounting hole is rotatably connected to the valve stem 301, and a sealing ring 600 is provided between the first mounting hole and the valve stem 301 to prevent leakage of the medium.

[0059] In this embodiment, a medium channel 3031 is opened on the steel ball 303. The valve stem 301 drives the steel ball 303 to rotate, so that the medium channel 3031 and the valve body channel can achieve different degrees of connectivity, thereby adjusting the opening of the stop valve 300.

[0060] Furthermore, the bottom of the valve stem 301 is connected to the steel ball 303 , wherein a clamping groove 3032 is provided on the steel ball 303 , and the clamping groove 3032 is clamped and connected to the end of the valve stem 301 .

[0061] The motor 100 in this embodiment is an intrinsically safe motor with explosion-proof properties, suitable for use in mines. Specifically, in this embodiment, the intrinsically safe motor is made of low-power semiconductor devices (such as MOSFETs and IGBTs) to reduce the risk of heat generation and sparks. A Zener barrier or isolation barrier is added to the circuit to limit energy transmission to hazardous areas. Electromagnetic shielding and filtering technologies are used to suppress high-frequency interference and prevent accidental discharges. The housing is made of impact-resistant and corrosion-resistant materials (such as stainless steel or anti-static plastic).

[0062] In this embodiment, in the underground environment of a coal mine, workers can drive the valve stem 301 to rotate through the motor 100, and then rotate the steel ball 303 to open or close the channel in the valve body 302, thereby adjusting the opening of the stop valve 300, and can also overcome the technical problem of the existing spherical stop valve having a large pressure difference at both ends and difficult to adjust the opening of the stop valve.

[0063] In this embodiment, to prevent the shutoff valve 300 from being difficult to operate when the motor 100 fails, the electric shutoff valve assembly further includes a manual device 500. The manual device 500 is connected to the output shaft of the motor 100 via a transmission member 700. When the motor 100 fails, the manual device 500 can be used to manually open and close the shutoff valve 300 to avoid affecting the work progress. Preferably, the manual device 500 is a handle or a handwheel.

[0064] Furthermore, in this embodiment, the transmission member 700 includes a first bevel gear 701 and a second bevel gear 702 that are meshed with each other, the first bevel gear 701 is connected to the output shaft of the motor 100, and the second bevel gear 702 is connected to the output end of the manual device 700, and the teeth of the first bevel gear 701 and the second bevel gear 702 are meshed with each other.

[0065] When the manual device 700 is operated to rotate, the meshing of the first bevel gear 701 and the second bevel gear 702 can drive the output shaft of the motor 100 to rotate, thereby driving the valve stem 301 to rotate, and ultimately achieving the rotation of the steel ball 303. In addition, the bevel gear connection method used in this embodiment can change the direction of transmission, allowing the manual device 700 to be located on the side of the motor 100, avoiding occupying space in the axial direction of the motor 100 and facilitating operation by personnel.

[0066] In some embodiments, the electric stop valve assembly further includes a reducer 200, which is disposed between the motor 100 and the stop valve 300, wherein the output shaft of the reducer 200 is connected to the valve stem 301, and the reducer 200 can adjust the speed output by the motor 100.

[0067] Furthermore, the output shaft of the reducer 200 is connected to the valve stem 301 via an adapter 201 , which facilitates the connection between the reducer 200 and the valve stem 301 , thereby facilitating the transmission of the torque output by the reducer 200 to the valve stem 301 .

[0068] Specifically, the adapter 201 includes a first connecting part 2011 and a second connecting part 2012. The first connecting part 2011 is connected to the output shaft of the reducer 200, and the second connecting part 2012 is sleeved on the end of the valve stem 301. The adapter 201 can transmit power to drive the valve stem 301 to rotate.

[0069] Furthermore, if Figure 3As shown, a limiting member 400 is provided on the outer side of the adapter 201. More specifically, the limiting member 400 includes a first limiting member 401 and a second limiting member 402. The first limiting member 401 is sleeved on the outer side of the adapter 201, and the second limiting member 402 is provided on the upper surface of the valve body 302. A second mounting hole is opened on the upper surface of the valve body 302, and the second limiting member 402 is installed in the second mounting hole.

[0070] When the output shaft of the reducer 200 drives the first limit member 401 to rotate through the adapter 201, it can interfere with the second limit member 402, thereby limiting the rotation angle of the output shaft of the reducer 200 through the interference between the second limit member 402 and the first limit member 401, thereby preventing the steel ball 303 from excessive rotation.

[0071] In a specific embodiment, Figure 3 As shown, the first limiting member 401 is a ring-shaped structure, which is convenient for being mounted on the adapter 201. A notch 4011 is provided on the first limiting member 401, and the circumferential length of the notch 4011 here is related to the rotation range of the adapter 201. The second limiting member 402 is a positioning pin, and the positioning pin 402 matches the notch 4011 and moves within the range of the notch 4011, thereby limiting the rotation angle of the first limiting member 4011.

[0072] A second embodiment of the present disclosure provides a control method for a stop valve, which is implemented using any of the above-mentioned stop valve systems and includes the following steps:

[0073] Step S100: inputting a stop valve opening adjustment instruction to the controller 800;

[0074] Step S200: the controller 800 controls the motor 100 to operate;

[0075] Step S300: The encoder 900 collects the operation information of the motor 100 and transmits the motor operation information to the controller 800; the controller 800 makes a judgment based on the operation information and obtains a motor output plan; the controller 800 controls the operation data of the motor 100 according to the motor output plan;

[0076] Step S400: the motor 100 operates according to the operating data to adjust the opening of the stop valve 300.

[0077] Specifically, in this embodiment, in step S300, the encoder 900 collects operating information of the motor 100 and transmits the motor operating information to the controller 800; the controller 800 makes a judgment based on the operating information to obtain a motor output plan; and the controller 800 regulates the operating data of the motor 100 according to the motor output plan, including:

[0078] Step S310: The encoder 900 monitors the position information of the motor 100 and transmits it to the controller 800;

[0079] Step S320: The controller 800 determines the opening of the stop valve 300 based on the position information. If the set stop valve opening requirement is met, the controller 800 outputs a stop operation instruction to the motor 100. If the set stop valve opening requirement is not met, the controller 800 outputs a start operation instruction to the motor 100.

[0080] In a specific embodiment of the present disclosure, the stop valve system monitors the position information of the motor 100 in real time through the encoder 900 and transmits it to the controller 800. The controller 800 converts the position information from the cumulative number of pulses into an opening percentage (0-100%, corresponding to the stop valve's rotary rod rotating 0-90°), and then uses a PID closed-loop control algorithm to dynamically adjust the direction and speed of the motor 100.

[0081] Furthermore, in this embodiment, in step S320, the controller 800 determines the opening of the stop valve 300 based on the position information. If the set stop valve opening requirement is met, the controller 800 outputs a stop instruction to the motor 100; if the set stop valve opening requirement is not met, the controller 800 outputs a start instruction to the motor 100, including:

[0082] Step S321: The encoder 900 monitors the speed data of the motor 100 and transmits the data to the controller 800;

[0083] Step S322: When the controller 800 determines that the opening of the stop valve 300 does not meet the set stop valve opening requirement, the controller 800 adjusts the operation data of the motor 100 according to the speed data. When the speed data is greater than the set speed value, the controller 800 controls the motor 100 to continue to operate according to the speed data. When the speed data is less than the set speed value, the controller 800 controls the motor 100 to increase the torque output. More specifically, the controller 800 increases the output current of the motor 100 to increase the torque of the motor 100.

[0084] In this embodiment, the output shaft of the motor 100 is connected to the reducer 200, and the output shaft of the reducer 200 is connected to the shut-off valve 300. When the speed data is less than the set speed value, the reducer 200 reduces speed and increases torque and opens.

[0085] For example, the set stop valve opening requirement is 50%, and the encoder 900 monitors the position information of the motor 100 in real time and converts the accumulated pulse number into an opening percentage of 30%, which is less than the set stop valve opening requirement of 50%, and does not meet the set stop valve opening requirement. The encoder 900 monitors the speed data of the motor 100 and transmits it to the controller 800. If the speed data is 2000r / s and the set speed value is 3000r / s, the speed data is less than the set speed value, and it is considered that the pressure of the load 1100 increases. The controller 800 uses a PID closed-loop control algorithm to dynamically control the motor 100 to increase the torque output. More specifically, the controller 800 increases the torque of the motor 100 by increasing the output current to the motor 100.

[0086] During the mine production process, the pressure of the load 1100 will often change. When the pressure of the load 1100 increases, it will cause the rotational resistance of the motor 100 and the speed to drop. When the speed data is less than the set speed value, or even when the speed is equal to zero, it will affect the opening adjustment of the stop valve 300, thereby affecting the entire working process. In this embodiment, by setting a controller 800 and an encoder 900, when the controller 800 determines that the opening of the stop valve 300 does not meet the set stop valve opening requirement and the speed data is less than the set speed value, the controller 800 increases the output current to the motor 100, increases the torque of the motor 100, and enables the stop valve 300 to adjust the opening size, thereby improving the working efficiency of mine mining.

[0087] In this embodiment, the stop valve system also includes a host computer 1000, which is electrically connected to the controller 800. People skilled in the art can set the opening requirement of the stop valve 300 through the host computer 1000, and then the host computer 1000 transmits the opening requirement of the stop valve 300 to the controller 800. The controller 800 adjusts the operating data of the motor according to the opening requirement of the stop valve 300, thereby realizing the opening adjustment of the stop valve 300.

[0088] This embodiment provides a control method for a stop valve, further comprising:

[0089] The encoder 900 monitors the current data of the motor 100 and transmits the current data to the controller 800. The controller 800 determines the motor temperature based on the current data. When the motor temperature exceeds the set temperature value, the controller 800 outputs a stop instruction to the motor 100 to avoid overheating and damage to the equipment.

[0090] This embodiment provides a control method for a stop valve, further comprising:

[0091] The encoder 900 monitors the current data of the motor 100 and transmits the current data to the controller 800. When the difference between the minimum current data and the maximum current data within a set time interval is greater than a set threshold, it is judged as a current mutation and the motor 100 is stalled. The controller 800 sends a stop signal or a reverse signal to the motor 100, and the controller 800 sends a fault warning signal to the host computer 1000 to remind the staff to take timely action.

[0092] This embodiment provides a control method for a stop valve, including:

[0093] The encoder 900 monitors the voltage data and current data of the motor 100, and then transmits the voltage data and the current data to the controller 800. The controller 800 determines whether the voltage data and the current data exceed the set voltage threshold and the set current threshold respectively. When the voltage data and / or the current data exceed the set voltage threshold and the set current threshold, the controller 800 cuts off the power supply to protect the equipment.

[0094] The disclosed embodiment can realize intelligent control of the stop valve, automatically adjust the valve opening size according to the set stop valve opening requirement, output different speeds and torques according to different working conditions, improve work efficiency, and speed up the work process compared with the existing technology; it can also automatically monitor the temperature, current and voltage of the motor to ensure the safety of the entire stop valve system.
