Abstract
Description
Technical Field
[0001] This invention relates to the field of gas valve technology, and in particular to a novel high-precision gas pressure regulating valve structure. Background Technology
[0002] A gas pressure regulating valve, commonly known as a gas pressure reducing valve, is an important gas appliance in household gas appliances that reduces and stabilizes output pressure. It boasts advantages such as simple structure, stable pressure, light weight, and convenient adjustment and installation. From a fluid mechanics perspective, a pressure reducing valve is a throttling element with variable local resistance. By altering the throttling area, it changes the flow velocity and kinetic energy of the fluid, resulting in varying pressure losses and thus achieving pressure reduction.
[0003] Currently, most gas pressure regulating valves require electrical power due to their internal electronic components. If the battery is depleted, the pressure valve readings become inaccurate, affecting operator judgment. Furthermore, the constant power consumption of the regulating valve adds a burden to the power grid. Therefore, those skilled in the art have proposed a novel high-precision gas pressure regulating valve structure to address the problems mentioned in the background section. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel high-precision gas pressure regulating valve structure. This novel high-precision gas pressure regulating valve structure utilizes the principle of kinetic energy to automatically generate electricity, thereby facilitating the supply of power to the battery and ensuring that the battery is always fully charged. This effectively prevents the valve from failing to function properly due to battery depletion. At the same time, the valve also has the function of automatically detecting the airtightness of the pressure regulating valve, thus making the pressure regulating valve more precise.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A novel high-precision gas pressure regulating valve structure includes a valve body. Two gears are rotatably mounted on one side of the valve body's inner wall. A rotating bracket is fixedly mounted on one side wall of each of the two gears and rotatably connected to the inner wall of the valve body. The two gears are meshed together. A converter and a battery are embedded in one side wall of the valve body. The converter is fixedly connected to one of the rotating brackets. Solenoid valves are installed through both ends of the valve body. A sealing cover is fixedly mounted on the upper surface of the valve body by multiple bolts. A pressure gauge is mounted on the upper surface of the sealing cover, and a sensor is fixedly mounted on its lower surface and electrically connected to the sensor.
[0006] Through the above technical solution, the two gears work together to drive the two rotating frames to rotate using the principle of kinetic energy. The converter can convert kinetic energy into electrical energy, which facilitates better detection of the airtightness of the pressure regulating valve. The sensor can also better sense the pressure.
[0007] Furthermore, a groove is provided on the lower surface of the sealing cover, a sealing block is slidably disposed on the inner wall of the groove, and a screw is rotatably disposed on the upper surface of the sealing block, with one end of the screw threaded through the sealing cover; The pressure can be controlled using the sealing block through the above technical solution.
[0008] Furthermore, the battery is electrically connected to the solenoid valve and the sensor; The above technical solution facilitates the supply of power to electronic devices.
[0009] Furthermore, the upper surface of the sealing cover is provided with a connector and is fixedly connected to the screw; The above technical solution facilitates the control of the screw.
[0010] The present invention has the following beneficial effects: 1. The present invention proposes a novel high-precision gas pressure regulating valve structure. Compared with the existing novel high-precision gas pressure regulating valve structure, when put into use, the two gears work together to drive the two rotating frames to rotate through the valve using the principle of kinetic energy. This causes the two gears to rotate, and the converter converts the kinetic energy into electrical energy, thereby generating electricity. The generated electrical energy is stored in a battery and used to power the electronic components inside the pressure regulating valve, thus achieving energy saving.
[0011] 2. This invention proposes a novel high-precision gas pressure regulating valve structure. Compared to existing high-precision gas pressure regulating valve structures, this novel structure, upon deployment, pumps gas into the valve body while simultaneously closing the solenoid valves at both ends, placing the valve body in a gas-storing state. Through the combined action of the sensor and pressure gauge, the valve body's sealing performance can be determined by observing the pressure gauge reading, thus facilitating the assessment of the pressure regulating valve's accuracy. If inaccurate, replacement is necessary to ensure the valve's precision. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.
[0015] Reference Figure 1-5 The present invention provides an embodiment of a novel high-precision gas pressure regulating valve structure, comprising a valve body 1, with two gears 14 rotatably disposed on one side of the inner wall of the valve body 1, and a rotating frame 13 fixedly disposed on one side wall of each of the two gears 14 and rotatably connected to the inner wall of the valve body 1, the two gears 14 being meshed and connected to each other, a converter 2 and a battery 3 being embedded in one side wall of the valve body 1, the converter 2 being fixedly connected to one of the rotating frames 13, and under the mutual cooperation of the two gears 14, the two rotating frames 13 can be driven to rotate using the principle of kinetic energy, and under the action of the converter 2, kinetic energy can be converted into electrical energy.
[0016] Solenoid valves 4 are installed through both ends of the valve body 1 to facilitate better detection of the airtightness of the pressure regulating valve. A sealing cover 7 is fixed to the upper surface of the valve body 1 by multiple bolts 5. A pressure gauge 8 is installed on the upper surface of the sealing cover 7, and a sensor 9 is fixedly installed on its lower surface and electrically connected to the sensor 9. The sensor 9 can better sense the pressure. A groove 10 is provided on the lower surface of the sealing cover 7. A sealing block 11 is slidably installed on the inner wall of the groove 10. A screw 12 is rotatably installed on the upper surface of the sealing block 11. One end of the screw 12 is threaded through the sealing cover 7. The pressure can be controlled through the sealing block 11. The battery 3 is electrically connected to the solenoid valve 4 and the sensor 9 to facilitate power supply to the electronic devices. A connector 6 is provided on the upper surface of the sealing cover 7 and is fixedly connected to the screw 12 to facilitate control of the screw 12.
[0017] Working principle: In use, this invention first pumps air into the valve body 1 to bring it to full pressure. Then, the solenoid valves 4 at both ends are closed simultaneously. Through the cooperation between the sensor 9 and the pressure gauge 8, the sealing performance of the valve body 1 can be measured. If the sealing performance is poor, it needs to be replaced. If the sealing performance is good, the solenoid valves 4 at both ends are opened simultaneously, thus ensuring that the pressure regulating valve is always in a high-precision state. Then, using the principle of kinetic energy, the gas flows through the valve and drives the rotating frame 13 and gear 14 to rotate. Under the action of the converter 2, the kinetic energy can be converted into electrical energy and stored in the battery 3 for later use to power the internal electronic components, thereby saving energy.
