Abstract
The invention discloses a method for detecting sealing performance. The method comprises the following steps of: putting a liquid container into a closed container; injecting water into the liquid container, and then sealing the liquid container; enabling the instant temperature in the closed container to rise, and transforming the water into water vapor; monitoring the instant concentration of the water vapor in the closed container; if the instant concentration rises, the liquid container is proved to have leakage; and if the instant concentration is not changed, the liquid container is proved to have no leakage. The method can be used for detecting the sealing performance of a product, thus accurately detecting the product quality, and preventing the accidents from happening in the subsequent using process.
Description
Technical field
The present invention relates to technical field of ships, relate in particular to a kind of sealing property detecting method.
Background technology
Sealing property is a very important index, but seldom be concerned, especially concerning boats and ships, its sealing property is its important index, otherwise can affect the ability to bear of boats and ships when meeting with fortuitous event, and for some boats and ships that can move under water, its sealing property needs more concerned, yet, lack the equipment that the sealing property of opposite house detects in the prior art, demand urgently improving.
Summary of the invention
Problem for prior art exists the object of the invention is to propose a kind of sealing property detecting method, can the sealing property of product be detected, thereby product quality is accurately detected, and prevents the generation of security incident in follow-up use procedure.
A kind of sealing property detecting method comprises the steps:
Described liquid container is placed in the closed container;
Seal behind the injected water in the described liquid container;
Improve the real-time temperature in the described closed container, described water is converted into water vapor;
Monitor the instant concentration of described water vapor in the described closed container, if described instant concentration raises, then leaking appears in described liquid container;
If described instant concentration is constant, then leaking does not appear in described liquid container.
The described sealing behind the injected water in the described liquid container is specially: seal after filling with water in the described liquid container, and make air pressure in the described liquid container greater than the outer air pressure of described liquid container.
The present invention proposes a kind of sealing property detecting method, can the sealing property of product accurately be detected, thereby product quality is detected, and prevents the generation of security incident in follow-up use procedure.
Description of drawings
Fig. 1 is the schematic flow sheet of a kind of sealing property detecting method in the embodiment of the invention.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
As shown in Figure 1, Fig. 1 is the schematic flow sheet of a kind of sealing property detecting method in the embodiment of the invention.
With reference to Fig. 1, a kind of sealing property detecting method that the present invention proposes comprises the steps:
S1, described liquid container is placed in the closed container.
Particularly, at first liquid container is placed in the closed container, then closed container is sealed.
S2, seal behind the injected water in the described liquid container.
Particularly, seal after filling with water in the described liquid container, and make air pressure in the described liquid container greater than the outer air pressure of described liquid container, if liquid container exists the position that water is overflowed all can detect.
Real-time temperature in S3, the described closed container of raising is converted into water vapor with described water.
Particularly, improve the temperature in the closed container, evaporate the water, form water vapor.
The instant concentration of described water vapor in S4, the described closed container of monitoring, if described instant concentration raises, then leaking appears in described liquid container.
If described instant concentration is constant, then leaking does not appear in described liquid container.
Even liquid container only exists minor amount of water to reveal, also can it be detected by the variation of measuring water vapor concentration, thereby accurately detect the sealing property of liquid container.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
Claims (2)
1. a sealing property detecting method is characterized in that, comprises the steps:
Described liquid container is placed in the closed container;
Seal behind the injected water in the described liquid container;
