The invention provides a vacuum faucet, and relates to the technical field of faucets. The vacuum faucet comprises a main pipeline and a control handle. A vacuum chamber is arranged at the end, away from the control handle, of the main pipeline, and an adjusting screw tube is arranged on the top face of the vacuum chamber in a penetrating mode. An adjusting device is arranged in the adjusting screw tube and comprises a servo motor and a transmission worm, and a supporting seat is arranged in the adjusting screw tube. The end of an output shaft of the servo motor is connected with the bottom end of the transmission worm, and a sealing cap is fixedly arranged at the top end of the transmission worm. Pressure relief holes are formed in the two sides of the outer wall of the adjusting screw tube in a penetrating mode, and the adjusting device conducts pressure relief treatment through the pressure difference value between a first pressure sensor and a second pressure sensor. When the servo motor operates, the transmission worm drives the sealing cap to rotate in a threaded mode on the outer wall of the adjusting screw tube to enable the pressure relief holes to be exposed for pressure relief, so that the purpose of pressure relief adjustment of a vacuum valve is achieved, the vacuum faucet can adapt to pressure relief critical pressure needed by pipelines made of different materials, pressure adjustment is more accurate, and the use for pressure relief treatment of the faucet is facilitated.
Description
technical field [0001] The invention relates to the technical field of faucets, in particular to a vacuum faucet. Background technique [0002] A faucet is a popular name for a water valve, which is used to control the size of the water flow. The faucet is not only used in daily households, but also is often used as an important part to control the on-off of pipelines in some chemical fields. However, in the process of long-term use, existing chemical There are some problems in the faucets used in the field. For example, when there is a lack of solution in the faucet pipeline, a vacuum will be formed in the pipeline, which will cause some faucets immersed in the solution to open when the pipeline is vacuumed and form a siphon backflow phenomenon. The conventional method is Add vacuum valve. [0003] Existing vacuum faucets cannot be adjusted according to the pressure value inside the actual pipe when adjusting the pressure, so that the value is not accurate enough when the ...
