Description

Technical Field

[0001] The utility model relates to the technical field of safety ball valves, in particular to a safety ball valve for a gas pipeline. Background Art

[0002] Ball valves were introduced in the 1950s. With the rapid development of science and technology, the continuous improvement of production technology and product structure, in just 40 years, they have rapidly developed into a major valve type. In Western industrially developed countries, the use of ball valves is increasing year by year. In my country, ball valves are widely used in oil refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electricity, municipal administration, steel and other industries. Safety ball valves play a vital role in gas pipelines.

[0003] A gas pipeline safety ball valve disclosed in the Chinese utility model patent application disclosure CN221034057U, although the device uses an alarm device, when gas leakage occurs, the gas detector identifies the gas, when the gas is identified, the gas detector will transmit a signal to the alarm, so that the alarm sounds an alarm, reminds the personnel, and prevents the occurrence of property loss to others due to gas leakage, but the existing device does not solve the problem that when the safety ball valve leaks, the gas leakage may continue when the personnel are not around, thus causing a dangerous accident. The safety ball valve is usually installed in the kitchen, and the excessive oil fume content in the kitchen may cause a large amount of oil and impurities to adhere to the valve stem rotation, so that the safety ball valve cannot be closed normally after the gas leak, resulting in continuous gas leakage. Therefore, we propose a new device to solve the above problem. Utility Model Content

[0015] In summary, the technical effects and advantages of the utility model are:

[0016] 1. The utility model has a reasonable structure. It senses gas leakage around the valve body through the combustible gas sensor, and reminds personnel of gas leakage through the alarm. After the reminder, the fixed motor drives the fixed shaft to rotate the fixed turntable and the fixed block. The rotation of the fixed block can drive the valve stem to rotate to close the internal pipeline of the valve body to prevent gas from continuing to leak. It solves the problem that when there is gas leakage in the safety ball valve, there is no personnel around, which may cause continuous gas leakage and cause dangerous accidents. It achieves the effect of first reminding personnel through the alarm and then closing the safety ball valve by rotating the fixed block to reduce gas leakage after gas leakage occurs, thereby greatly enhancing the safety of the safety ball valve.

In the utility model, the cleaning agent in the cleaning box is discharged into the pipeline through a hose by a water pump, and then the cleaning agent is sprayed on the rotating part of the valve stem through a nozzle, thereby solving the problem that the safety ball valve is usually installed in the kitchen and the oil smoke content in the kitchen is too high, which may cause a large amount of oily impurities to adhere to the rotating part of the valve stem and affect the normal rotation of the valve stem. The cleaning agent can be sprayed on the rotating part of the valve stem regularly to soften the oily impurities at the rotating part of the valve stem and facilitate subsequent cleaning. The cleaning roller is rotated by the cleaning motor to clean the rotating part of the valve stem after the cleaning agent is sprayed. After cleaning, the cleaned part is dried by the fan, thereby solving the problem that the safety ball valve cannot be closed normally after gas leakage due to a large amount of oily impurities adhering to the rotating part of the valve stem, resulting in continuous gas leakage. The effect of continuously cleaning the surface of the rotating part of the valve stem after the oily impurities are softened to remove the oil on its surface can be achieved, thereby greatly reducing the situation where the valve stem cannot rotate.

[0026] As a preferred implementation in this embodiment, Figure 1-Figure 3As shown, the surface of the valve body 1 is fixedly connected to a base 2, the upper surface of the base 2 is fixedly connected to a bracket 3, the front surface of the bracket 3 is fixedly connected to a combustible gas sensor 4, the interior of the bracket 3 is fixedly connected to a fixed motor 5, one end of the fixed motor 5 is plugged with a fixed shaft 6, a docking hole is provided on the lower surface of the front end of the bracket 3, the bracket 3 is rotatably connected to the fixed shaft 6 through the docking hole, the surface of the fixed shaft 6 is fixedly connected to a fixed turntable 7, the lower surface of the fixed turntable 7 is fixedly connected to a fixed block 8, the combustible gas sensor 4 is located near the lower part of the front side of the bracket 3, and the fixed block 8 is fixedly connected to the fixed motor 5. 8 is located at the lower surface of the fixed turntable 7 near the back, the upper surface of the bracket 3 is fixedly connected to an alarm 9, the left side of the base 2 is fixedly connected to a cleaning box 10, the front of the cleaning box 10 is fixedly connected to a water pump 11, one end of the water pump 11 is plugged with a hose 12, one end of the hose 12 is plugged with a positioning rod 13, the upper surface of the valve body 1 is provided with a groove, the valve body 1 is fixedly connected to the positioning rod 13 through the groove, the lower surface of the positioning rod 13 is plugged with a nozzle 14, the interior of the positioning rod 13 is provided with a pipeline, the hose 12 is adapted to the nozzle 14 through the through-pipe, and the nozzle 14 is adapted to the nozzle 14 through the through-pipe. During the process, the combustible gas sensor 4 senses the gas leakage around the valve body 1, and the alarm 9 reminds the personnel of the gas leakage. After the reminder, the fixed motor 5 drives the fixed shaft 6 to rotate the fixed turntable 7 and the fixed block 8. The rotation of the fixed block 8 can drive the valve stem to rotate to close the internal pipeline of the valve body 1 to prevent the gas from continuing to leak. This solves the problem that when the safety ball valve leaks gas, the absence of personnel around may cause continuous gas leakage and cause dangerous accidents. After the gas leak occurs, the alarm 9 is used to remind the personnel first, and then the safety ball is rotated to make the fixed block 8 The valve closing reduces the effect of gas leakage and greatly enhances the safety of the safety ball valve. The cleaning agent inside the cleaning box 10 is discharged into the pipeline through the hose 12 by the water pump 11, and then the cleaning agent is sprayed on the rotating part of the valve stem through the nozzle 14 to soften the oil and dirt impurities attached to the rotating part of the valve stem.

The effect of continuously cleaning the surface of the valve stem rotation part after the oil impurities are softened to remove the oil on its surface has been achieved, which greatly reduces the situation where the valve stem cannot rotate.

[0028] How this utility works:

[0029] During use, the combustible gas sensor 4 senses the gas leakage around the valve body 1, and the alarm 9 reminds the personnel of the gas leakage. After the reminder, the fixed motor 5 drives the fixed shaft 6 to rotate the fixed turntable 7 and the fixed block 8. The rotation of the fixed block 8 can drive the valve stem to rotate to close the internal pipeline of the valve body 1 to prevent the gas from continuing to leak, which solves the problem that when the safety ball valve leaks, the gas leakage may continue when the personnel are not around, thus causing a dangerous accident. After the gas leak occurs, the alarm 9 is used to remind the personnel first, and then the safety ball valve is closed by rotating the fixed block 8 to reduce the gas leakage, which greatly enhances the safety of the safety ball valve. The detergent in the cleaning box 10 is discharged into the pipeline through the hose 12 through the water pump 11, and then the detergent is sprayed on the rotating part of the valve stem through the nozzle 14 to soften the oil and impurities attached to the rotating part of the valve stem, which solves the problem that the safety ball valve is usually installed The kitchen and the excessive oil smoke content in the kitchen can easily cause a large amount of oil and impurities to adhere to the valve stem rotation point, affecting the normal rotation of the valve stem. The valve stem rotation point can be sprayed with detergent at regular intervals to soften the oil and impurities at the valve stem rotation point for subsequent cleaning. The driving seat 17 is moved backward by the hydraulic rod 16, and the driving motor 18 rotates the driving shaft 19 to rotate the driving turntable 20, and then the cleaning motor 21 is used to rotate the cleaning roller 22, so that the valve stem rotation point after spraying the detergent can be cleaned. After cleaning, the cleaned point is air-dried by the fan 15 to avoid rust at the valve stem rotation point, and the problem of a large amount of oil and impurities adhering to the valve stem rotation point, which leads to the inability to normally close the safety ball valve after gas leakage, resulting in continuous gas leakage, is solved. The surface of the valve stem rotation point can be continuously cleaned after the oil and impurities are softened to remove the oil on its surface, which greatly reduces the situation where the valve stem cannot rotate.
