Description
Technical Field
The present invention relates to the field of aerosol containers for the delivery of liquid or semi-liquid contents by internal gas pressure, and in particular to aerosol canisters for gas leak detection, such as those suitable for gas leak detection, particularly for the detection of natural gas leaks.
Background
The detection agent for detecting the leakage condition is a leakage detection agent or a gas leakage detection spray, and is used for detecting the sealing performance in scenes such as pressure containers, gas cookers, air-conditioning pipelines, automobile maintenance, locomotive maintenance, oil pressure machines, large storage tanks, natural gas conveying pipelines and the like, and the sealing detection of gas container pipelines, particularly natural gas, is particularly common. The sealing integrity of the pipeline, the valve, the joint, the welding line and other parts is ensured no matter in the production process or the maintenance process, and the sealing structure is the basis for ensuring the good operation of the whole set of equipment. The gas leakage has many hazards, reduces the pressure of the container pipeline, brings dangerous hidden dangers, influences the operation and even can have serious consequences.
The detection of gas leakage commonly used in industrial inspection is different according to different gas modes, and combustible, toxic and other special gas leakage is detected by special detection technologies and tools. If the common compressed air leaks, the automobile tire and bicycle tire can be pricked according to life experience, and the automobile tire and bicycle tire are generally smeared with soap water to see where the leakage point exists during maintenance, and then repair measures are taken. Leak detection is performed based on the principle: when a pressure difference exists between the two sides of the leakage hole, the gas flows from the high-pressure side to the low-pressure side through the leakage hole, and if proper display liquid (such as detergent, soap solution, special leakage detection liquid and the like) is applied to the low-pressure side, bubbles can emerge from the leakage position, so that the position of a leakage point is indicated. And then carrying out next sealing and maintenance treatment according to the position of the leakage point.
The leak detector can be filled in an aerosol can for convenient operation, the aerosol can is a spray can which is used for pushing another fluid out of the spray can by the fluid stored under high pressure, and the complete pressure packaging container consists of a valve, a container and contents (including a product material and a propellant), the valve can be a pressing valve, when the pressing valve is pressed, the valve is opened, the contents are released in a predetermined pressure and control mode, and the spray-shaped projection of the product is realized. The aerosol system can be divided into two types of mixed two-phase systems, the two types of separated two-phase systems, and the specific structure has various sizes and shapes and serves as a container for various substances. If natural gas is subjected to leakage detection, methane is a main component, and is worth noting, methane is a greenhouse gas, and methane is the second largest greenhouse gas in the world next to carbon dioxide, and the unit greenhouse effect of methane is more than 20 times of that of carbon dioxide, and is one of the main gases causing the greenhouse effect.
In the prior art, on the one hand, when checking the condition of leaking, there is the arduous problem of pressing the valve operation, when using in normal atmospheric temperature or the environment more than 0 ℃, this problem can not show basically, but when using under the environment that is less than 0 ℃, this problem just can be obvious, can appear pressing down the unable blowout of product material of leakage detection agent, leads to being difficult to the effectual effective detection that carries out natural gas high pressure vessel and pipeline under low temperature, ultralow temperature.
On the other hand, in order to reach better foamability, when the product material is the polycomponent, behind the long-time placing of aerosol jar, can appear, because of the action of gravity, there is partial product material to precipitate in jar body bottom, this partial product material will be difficult to spout, even can spout, the inhomogeneous spun problem of product material appears very easily when casting, not only cause the jam to the aerosol jar valve easily when casting, and also can lead to the steady bubble performance of spun product material poor, be difficult to realize fine steady bubble nature, thereby lead to spun leak testing agent to spout behind the leakage position of waiting to examine, can not reach anticipated detection effect.

In the embodiment, in order to realize the situation that the product material in the aerosol tank valve cannot be sprayed, considering that the common liquid material can be frozen when used in the environment below 0 ℃, the inventor adds the colloid material on the basis of the existing liquid material to detect the spray, the colloid material capsule body 2 is arranged in the tank body 1 and is used for containing the colloid material, for example, guar gum can be selected as the colloid material to be added, the colloid material has lower freezing point, the liquid material capsule body 3 is arranged and is used for containing the liquid material, for example, the bubble liquid capable of generating bubbles, in order to avoid the bubbles being frozen, on one hand, different types of antifreeze can be respectively added into the liquid material capsule body and the colloid material capsule body, the antifreeze can not be frozen below 0 ℃ like automobile glass water, thereby realizing that the colloid material and the liquid material cannot be frozen below 0 ℃, when the valve 5 is pressed, the colloid material and the liquid material can be well sprayed, and the problem that the leakage detection agent cannot be sprayed when the valve 5 is pressed down when the device is used in an environment at the temperature of less than 0 ℃ is avoided.
In the initial stage of research and development, colloid material is added, the primary purpose is mainly to increase the foam stability of liquid material so that the thrown liquid can achieve the best foaming effect, the colloid material capsule body 2 and the liquid material capsule body 3 are not separately designed at first, but one capsule body is designed to contain the mixed colloid material and liquid material at the same time, and an antifreezing agent is added, although the problem of freezing under low-temperature environment can be solved to a certain extent, the actual problem is faced, the problem that the sprayed leakage detection product material is uneven due to layering of the colloid material and the liquid material is caused, because the product material is a multi-component combination and contains the colloid material, after the aerosol can is placed for a long time, part of the colloid material is deposited at the bottom of the can body due to the action of gravity, the part of the product material is difficult to be sprayed, even if the product material can be sprayed, the problem of uneven spraying of the product material is easy to occur during the spraying, and not only the aerosol valve is easy to be blocked during the spraying, and the sprayed product material has poor foam stabilizing performance and is difficult to realize good foam stabilizing performance, so that the sprayed leakage detection agent cannot achieve the expected detection effect after being sprayed to the leakage position to be detected. In order to solve the problem, through continuous improvement design for two sacks, colloid material utricule 2 and liquid material utricule 3 carry out the splendid attire to the colloid material respectively, carry out the splendid attire to foaming liquid material, thereby the emergence of colloid material sinking tank bottoms has been avoided, and liquid material utricule 3 has added antifreeze and has avoided it to freeze below 0 ℃, use also consider adding antifreeze in the colloid material to prevent frostbite if need under lower temperature environment, thereby make still can carry out leak detection under winter day low temperature environment, certainly if need add other components, also can increase the mixing that the material was carried out to the fourth utricule of third when using.
At this moment, the colloid material passes through the independent splendid attire of colloid material utricule 2, the liquid material passes through the independent splendid attire of liquid material utricule 3, and add antifreeze, though solved colloid material and liquid material can the layering problem, the problem that can freeze below 0 ℃, face a new problem, colloid material and liquid material mix if getting into and valve outlet 502 blowout time from the valve entry 501 according to pressing valve 5 promptly, whether can realize required mixed effect, the foaming effect, the foam stabilizing effect, through the actual experiment, actual foaming effect and foam stabilizing effect do not reach the best foaming, and do not realize strong foam stability, for this inventor has designed mixing element 4 and has carried out the pre-mixing before throwing to colloid material and liquid material specially, in order to realize having improved actual mixed effect, the foaming effect, reach strong foam stability.
It should be noted that, in this embodiment, the mixing chamber 401 is a cavity, and the cavity can achieve better mixing at first, but there is no partition to partition the colloid material and the liquid material in the mixing chamber 401, and although better mixing at first can be achieved, the implementation of the cavity still has the problem that the colloid material sinks to the bottom of the mixing chamber 401 in a bag where the colloid material and the liquid material coexist, so that the product material is not uniformly sprayed out, and the situation that the aerosol can valve is easily blocked during projection still has a certain probability and possibility, and therefore, the subsequent embodiments are further improved to perfect the tiny problem.
