[0024] Please see Figure 1-4 This utility model provides an embodiment: an industrial valve assembly, including a battery compartment 16 and a ball valve body 28.

A ball sealing ring 12 is disposed on the left side of the rotating ball 13. Spring bodies 10 are disposed inside both sides of the ball valve body 28, and spring caps 15 are disposed on both sides of the ball valve body 28. A flow detection module 36 is installed on the left side of the top of the ball valve body 28, and a microchannel 26 is disposed on the flow detection module 36. A motor body 24 is fixed to the left side inside the reducer housing 3, and the motor body 24... A motor gear 29 is fixedly installed at the middle position of the top. A first-stage gear 30 is movably installed at the rear end of the left side of the top of the motor body 24. A gear shaft 33 is movably connected to the rear end of the top of the motor body 24, and a second-stage gear 32 is fixed to the outside of the gear shaft 33. A fourth-stage gear 25 is movably connected to the right side of the front end of the top of the motor body 24, and a third-stage gear 31 is fixed to the top of the fourth-stage gear 25. An output shaft 5 is vertically arranged on the right side inside the reducer housing 3, and an output gear 4 is fixed to the outside of the output shaft 5. A ball shaft body 7 is vertically arranged inside the right side of the top of the ball valve body 28, and a backstop pad 8 is arranged on the outside of the ball shaft body 7. A retaining ring 22 is arranged on the top of the backstop pad 8. A ball shaft sealing ring 6 is fixed to the top of the outside of the ball shaft body 7. A display PCB 27 is fixed to the front end of the ball valve body 28. A circuit board 23 is fixed to the left side of the bottom end of the ball valve body 28. A housing sealing ring 9 is fixed to the outside of the ball valve body 28.

[0025] The top end of the ball shaft body 7 is fixedly connected to the bottom end of the output shaft 5. The bottom end of the ball shaft body 7 passes through the top end of the ball valve body 28 and is inserted into the interior of the top end of the ball shaft body 7. The motor gear 29 is meshed with the first-stage gear 30. The first-stage gear 30 is meshed with the second-stage gear 32. The second-stage gear 32 is meshed with the fourth-stage gear 25. The third-stage gear 31 is meshed with the output gear 4. The spring cover 15 is threaded and rotatably connected to the interior of both sides of the ball valve body 28. The microchannel 26 is connected to the interior of the reducer cover 2. The rear shell 1 is installed and fixed to the battery compartment 16 by bolts.

[0026] Specifically, such as Figures 1-4 As shown, in the open state, gas enters the ball valve body 28. When it passes through the damping pipe section 11, the gas pressure changes, and the gas pressure in the microchannel 26 generates a pressure difference. The flow detection module 36 senses the pressure difference and measures the gas flow and pressure. The main control circuit board 23 collects the gas flow and pressure signals and judges whether there are abnormal flow such as overflow and abnormal pressure such as underpressure or overpressure according to the set parameters. When abnormal flow or pressure occurs or the user does not use gas, the main control circuit board 23 sends a valve closing signal. The rotating ball 13 is controlled to rotate through the deceleration component and the output shaft 5 to cut off the gas pipeline. An alarm is displayed on the PCB 27 to realize gas safety monitoring and valve closing when gas is not used.

[0027] When the valve is closed, the flow detection module 36 can sense the differential pressure of the microchannel 26 in real time to measure the gas flow and pressure. The main control circuit board 23 collects the gas flow and pressure signals and judges whether there is micro-leakage or pressure abnormality of the gas according to the set parameters. When micro-leakage or pressure abnormality occurs, the alarm prompt is displayed on the PCB 27 and the valve is prohibited from being opened, so as to realize the online automatic safety inspection of the gas pipeline and the safety monitoring of gas leakage.

[0028] When the gas stove is ignited in the closed state, the pressure at the gas outlet drops, creating a pressure difference in the gas pressure of the microchannel 26. The flow detection module 36 senses the pressure difference and measures the gas flow and pressure. The main control circuit board 23 collects the gas flow and pressure signals and, under the condition that there is no abnormal gas microleakage, issues a valve opening signal. The rotating ball 13 is controlled to rotate through the deceleration component and output shaft 5 to open the gas pipeline, realizing automatic ignition of gas, ensuring safe and convenient gas use, and providing a prompt through the display PCB 27.

[0029] Battery positive electrode plates 18 are fixed to the rear ends of both sides inside the battery compartment 16, battery positive and negative electrode plates 19 are fixed to the middle positions of both sides inside the battery compartment 16, and battery negative electrode plates 20 are fixed to the front ends of both sides inside the battery compartment 16. Dry cell batteries 34 are installed between the battery positive electrode plates 18, battery positive and negative electrode plates 19 and battery negative electrode plates 20, and four sets of dry cell batteries 34 are provided. Battery compartment cover 17 is snapped onto the bottom of the battery compartment 16.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, by using the positive electrode 18, positive and negative electrode 19 and negative electrode 20 on both sides of the battery compartment 16, four sets of dry batteries 34 are connected in series to power the flow detection module 36 and the motor body 24. When replacing the power supply, the battery compartment cover 17 can be closed at the bottom of the battery compartment 16, and then the four sets of dry batteries 34 installed inside the battery compartment 16 can be quickly disassembled and replaced.

[0031] A fixing screw 21 is provided at each of the four corners at the bottom of the ball valve body 28, and the bottom end of the fixing screw 21 penetrates the interior of the ball valve body 28. A column 35 is fixed at each of the four corners at the bottom of the battery compartment 16, and a screw hole is opened in the interior of the top of the column 35. The bottom end of the fixing screw 21 is threaded and rotated to connect to the interior of the top of the column 35.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, the ball valve body 28 is installed and fixed to the inside of the battery compartment 16 by four sets of fixing screws 21. The split structure allows for quick disassembly, assembly, inspection and maintenance of the internal components of the industrial valve.

[0033] Working Principle: When this utility model is in use, the industrial valve assembly is connected to a gas pipeline. Gas enters from the right side of the ball valve body 28 and then exits from the left side. In the open state, gas enters the ball valve body 28. When it passes through the damping section 11, the gas pressure changes, and a pressure difference is generated in the microchannel 26. The flow detection module 36 senses the pressure difference and measures the gas flow and pressure. The main control circuit board 23 collects the gas flow and pressure signals and, based on the set parameters, determines whether there are abnormalities such as overflow or pressure abnormalities such as underpressure or overpressure. When abnormalities occur in flow or pressure, or when the user does not use gas, the main control circuit board 23 sends a valve closing signal. Through the deceleration component and output shaft 5, it controls the rotating ball 13 to rotate, cutting off the gas supply. The pipeline, and through the alarm prompt on the display PCB27, realizes gas safety monitoring and valve shut-off when gas is not needed. When the industrial valve assembly is in use, four sets of dry batteries 34 are connected in series by the positive electrode 18, positive and negative electrode 19 and negative electrode 20 on both sides of the battery compartment 16 to power the flow detection module 36 and the motor body 24 on the valve, to detect and drive the opening and closing of the rotating ball 13. When the power supply is replaced, the battery compartment cover 17 can be put off at the bottom of the battery compartment 16, and then the four sets of dry batteries 34 installed inside the battery compartment 16 can be quickly disassembled and replaced. The ball valve body 28 is installed and fixed to the inside of the battery compartment 16 by four sets of fixing screws 21, which is a split structure.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
