Negative-pressure cabin humidifying device with isolating and sealing functions

Abstract

The invention discloses a negative-pressure cabin humidifying device with isolating and sealing functions. The negative-pressure cabin humidifying device with the isolating and sealing functions comprises a heating tank and a water supplementing tank, wherein the left side of the water supplementing tank is connected with the right side of the heating tank; the top of the water supplementing tank is communicated with a water inlet pipeline; and a water inlet electromagnetic valve is arranged on the surface of the water inlet pipeline. The invention relates to the technical field of negative-pressure cabin humidifying equipment. According to the negative-pressure cabin humidifying device with the isolating and sealing functions, when an environment simulation cabin simulates a normal-pressure environment, no pressure difference exists inside and outside the cabin, and the negative-pressure cabin humidifying device can still work normally, so that the interior of the cabin is humidified; a humidifying tank is formed by combining the two tanks, one tank is the heating tank, the other tank is the water supplementing tank, and water level information is collected in the water supplementing tank, so that the water level can be prevented from being influenced by water level fluctuation caused by water vaporization, and more accurate control is achieved; and meanwhile, the two tanks are connected through a pressure balance pipe, so that pressure balance and the same water level of the two tanks are guaranteed, isolating and sealing with the outside atmosphere can be achieved, and the stable humidifying effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of humidifying equipment for a negative pressure chamber, in particular to a humidifying device for a negative pressure chamber with the function of isolation and sealing. Background technique [0002] The current multi-environmental load simulation cabin, this kind of simulation cabin can realize the simulation of environmental parameters such as temperature and humidity, air pressure, oxygen concentration, etc., and can carry out high-altitude animal and plant survival experiments, so in the high-altitude environment, the other components in the cabin are relatively low, compared with ordinary Compared with the air pressure at altitude, it is a negative pressure environment in the cabin. In a negative pressure environment, it is necessary to control the humidity in the cabin. When humidification is required, if an ordinary humidifier is used for humidification, the negative pressure will affect the working...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a negative pressure chamber humidification device with the function of isolation and sealing, which solves the problem of using ordinary humidifiers for humidification. The tank is sucked into the cabin, which will not only cause the pressure in the cabin to be unstable, but also cause the problem that the humidifying water cannot be boiled or humidified due to the low temperature of the outside air.
