A digital display Martens flask and its manufacturing method

Abstract

The invention provides a digital display Marriotte bottle and a manufacturing method. The digital display Marriotte bottle is composed of a water storage pipe (1), a base (2), a bottom cover (3), a top cover (4), an air inlet pipe (5), a water outlet pipe (6), a water supplementing pipe (7), an exhaust pipe (8), a rubber plug (9), an air vent pipe (10), a digital display vacuum meter (11) and a cut-off valve (12). The manufacturing method of the digital display Marriotte bottle comprises the steps of Marriotte bottle manufacturing, wherein the water storage pipe (1) is in perforated communication with the air inlet pipe (5) and the water outlet pipe (6), the bottom cover (3) is in perforated connection with the water supplementing pipe (7), the top cover (4) is in perforated connection with the exhaust pipe (8) and the rubber plug (9), a pipe opening of the water storage pipe (1) is sealed by the bottom cover (3) and the top cover (4), and the bottom cover (3) is fixed to the base (2); 2 digital display system manufacturing, wherein the rubber plug (9) is in perforated connection with the air vent pipe (10), the other end of the air vent pipe (10) is connected with the cut-off valve (12), and the other end of the cut-off valve (12) is connected with the digital display vacuum meter (11).

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to the manufacturing technology of detachable digital display Martens bottles. Background technique [0002] The Martens bottle is a measuring device that can control the water level and can automatically and continuously replenish water. It is widely used in the soil infiltration evaporator of the groundwater balance field and the water supply measurement system of the laboratory. The traditional Martens jar is made of ordinary glass with a scale on the glass surface. During use, the change of the water level is judged by visually observing the scale of the concave liquid surface in the bottle, which often causes certain errors. Agricultural irrigation techniques such as drip irrigation, infiltration irrigation and micro-moisture irrigation require a certain working water head (2~10m). dangerous.

Problems solved by technology

The traditional Martens bottle is made of ordinary glass with a scale on the glass surface. During use, the water level change is often judged by observing the concave liquid surface scale in the bottle with the naked eye, which often causes certain errors.

Agricultural irrigation techniques such as drip irrigation, infiltration irrigation and micro-moisture irrigation require a certain working water head (2~10m). dangerous
