2results about How to "Resolve inaccuracies" patented technology

This utility model discloses a battery health detection circuit and detection terminal, including: a voltage detection module, a load module, a control module, and a load switching module; the control module is electrically connected to the load module through the load switching module; the load module is electrically connected to the control module through the voltage detection module; the positive terminal of the load is electrically connected to the positive terminal of the battery. Beneficial effects: Through dynamic load switching and voltage difference detection, the battery health status can be predicted in advance, avoiding the interruption of backup power function due to sudden battery failure, and ensuring that the equipment can still work normally when the mains power is lost.

This invention discloses a pressure regulating and stabilizing device for a casing gas venting valve in oil wells, belonging to the field of oilfield well maintenance technology. It includes a connecting pipe connected to a nitrogen source, a venting valve, and a pressure gauge. The venting valve is equipped with an adjustment knob. This invention involves adding nitrogen to the connecting pipe to reach the required pressure for the venting valve. Once the required pressure is reached, the venting valve is adjusted using the adjustment knob until it begins to release gas and pressure normally. This pressure regulating method ensures accurate setting of the venting valve. This invention also discloses a pressure regulating and stabilizing method for a casing gas venting valve in oil wells. Using the aforementioned pressure regulating and stabilizing device, first, the venting valve and pressure gauge are connected to the connecting pipe. Then, nitrogen is injected into the connecting pipe. After observing the pressure gauge reading and reaching the required stabilizing pressure value, nitrogen injection is stopped. The venting valve is then adjusted using the adjustment knob until it begins to release gas and pressure normally.
