specific Embodiment approach 1

[0039] Combine below Figure 1-15 Describe this embodiment, a negative pressure steam generating device, including a device bracket 1, a negative pressure mechanism 2, a control mechanism 3, a one-way mechanism 4, a pushing mechanism 5 and an air extraction mechanism 6, which can be The screw threads of the two threaded rods I2-8 are in opposite directions. When the two threaded rods I2-8 rotate together, the two threaded rods I2-8 drive the two push pistons 2-11 to slide in the negative pressure cylinder 1-1. The two push pistons 2-11 are close to or far away from each other. When the two push pistons 2-11 are far away from each other, the negative pressure cylinder is in a sealed state under the action of the one-way mechanism 4. The volume between the two push pistons 2-11 Relatively becomes larger, the water vapor content between the two push pistons 2-11 is constant, and the water vapor between the two push pistons 2-11 forms a negative pressure, which is measured by the ...

Abstract

The invention relates to a negative pressure generating device, in particular to an efficient negative pressure steam generating device. The device comprises a device support, a negative pressure mechanism, a control mechanism, a one-way mechanism, a pushing mechanism and an air pumping mechanism. According to the efficient negative pressure steam generating device, the threaded rotation directions of two threaded rods I arranged on the negative pressure mechanism are opposite, the two threaded rods I drive two pushing pistons to slide in a negative pressure cylinder when the two threaded rodsI rotate together, the two pushing pistons are close to or far away from each other, when the two pushing pistons are far away from each other, the negative pressure cylinder is enabled to be in a sealed state under the action of the one-way mechanism, the volume between the two pushing pistons relatively becomes large, the content of water vapor between the two pushing pistons is unchanged, thewater vapor between the two pushing pistons forms negative pressure, and an air pressure meter is used for measuring the negative pressure; and the formed negative pressure is controlled through the control mechanism, the control mechanism is adjusted so that the movement of the negative pressure mechanism is certain and the formed negative pressure is certain, and the same negative pressure can be formed repeatedly and efficiently.

Description

technical field [0001] The invention relates to a negative pressure generating device, more specifically a negative pressure steam generating device. Background technique [0002] For example the one-way valve of publication number CN2652427 negative pressure generator. It includes a base, which is provided with a movable cork matched with the air nozzle of the base, and is also provided with a ventilation support behind the movable cork. The utility model has a relatively convenient assembly and a simple structure, overcomes the randomness and instability of the artificial valve cladding film, can not only ensure the working effect of one-way ventilation, but also control its quality, and meet the needs of industrial production. The utility model also provides a negative pressure generator for a disposable negative pressure container. It includes an airbag with an opening that cooperates with the negative pressure container and the outside world, and at least one opening ...
