The electric control ball valve is prior art, so it is not described in detail.
[0005] The improvement of the utility model lies in that a gas collection module is arranged on the gas pipeline in front of the electric control ball valve, which is used to lead out gas from the pipeline; the gas collection module is connected with a gas combustion module, which is used to burn the led-out gas and convert the generated heat into electric energy; and an electric energy storage module is further arranged, which is used to store electric energy and provide power output through an interface to supply power for the electric control ball valve.

[0012] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0013] Referring to Figure 1 A gas-driven self-powered ball valve.
[0014] It mainly includes the following parts:
[0015] Electric control ball valve 1: composed of electric actuator 101 and ball valve 102, its working principle is to receive control signals by electric actuator 101 and convert them into mechanical movement, and then drive the ball of ball valve 102 to rotate, so as to realize the on-off and flow regulation control of the medium in the pipeline. The electric control ball valve 1 here is prior art, so it will not be described in detail.
[0016] Gas collection module 2: located on the gas pipeline in front of the electric control ball valve 1, used to draw out gas from the pipeline. This module can draw out the medium in the pipeline to provide a basis for subsequent power generation.
[0017] Gas combustion module 3: connected between gas collection module 2 and subsequent electric energy storage module 4, used to burn the drawn gas, and convert the heat energy of the gas into electric energy by using the generated heat.
[0018] Electric energy storage module 4: used to store electric energy and provide power output through the interface to power the electric control ball valve 1 and the entire system. This module can store energy in various ways, such as lithium-ion batteries, fuel cells, etc. When there is no power in the field or when the power is off, the electric energy storage module 4 can provide the required electric energy to enable the electric control ball valve 1 to continue to operate.
[0019] The control module 5 comprises sensors, power detection devices and control circuits, can monitor the power storage state in real time, and starts the combustion module to generate power again when the power is insufficient, and controls the start and stop of the gas combustion module 3 as required to ensure the normal work of the electric control ball valve 1. The communication module 6 is arranged in the control module 5, and is responsible for information interaction and instruction receiving of the device and the control center. When there is no power, the communication module 6 can receive the instructions of the control center through wireless signals, and convert them into appropriate control signals, so as to drive the work of the electric control ball valve 1. At the same time, the communication module 6 can also send the state information of the electric control ball valve 1 to the control center.
[0020] The safety module is mainly used for preventing backfire and ensuring system safety. When the gas combustion module 3 starts, the safety module monitors the combustion process and takes measures as necessary to ensure safety. At the same time, the safety module can also monitor the state of the electric energy storage module 4 and issue an alarm as necessary to remind the operator to handle in time.
[0021] In the embodiment, the electric opening and closing valve 7 with a check device between the gas collection module 2 and the gas combustion module 3 can control the supply of gas, and the check device can prevent backflow and also serve as a safety protection. In some necessary cases, a pressure reducing valve can be additionally arranged.
[0022] In the embodiment, the gas combustion module 3 can usually be a gas internal combustion engine generator set, which usually comprises a combustion system that can burn the gas provided by the gas collection module 2 to generate high-temperature and high-pressure gas, a gas turbine that expands the high-temperature and high-pressure gas to do work and push the impeller of the gas turbine to rotate at high speed to convert the heat energy of the gas into mechanical energy, and a generator connected with the gas turbine through a shaft coupling to convert the mechanical energy into electric energy. The generator usually comprises a stator and a rotor, the stator is fixed and has a coil wound therein, and the rotor rotates in the stator to generate an alternating magnetic field to induce an electromotive force in the stator coil to output electric energy. This part is prior art and will not be described in detail. Of course, a simple design can also be adopted, for example, the gas combustion module 3 is a combustion chamber, and a thermoelectric conversion system 8 is arranged outside the combustion chamber to directly convert heat into electric energy by using thermoelectric conversion technology.
