Description

Technical Field

[0001] The utility model relates to a test tool, in particular to an auxiliary tool for applying airtightness test reagents. Background Technique

[0002] At present, for the inspection of horizontal containers containing flammable and explosive media, the internal and external conventional methods are used for inspection plus the final airtightness test to ensure the inspection quality and use safety of the horizontal containers. At present, the regular inspection mainly focuses on the partial inspection of the internal and external parts of the horizontal containers to analyze the equipment quality. Therefore, the overall airtightness test is very important. It is the last step of the inspection link and also the last safety defense line before putting into use. Inspectors also participate in the inspection throughout the airtightness test process. The airtightness test is mainly divided into two steps. One is the application of airtightness reagents, and the other is the observation after reaching the test pressure. Among many horizontal containers inspected, the manhole cover on the top of the container and the flange seals of each nozzle are the key points of the airtightness test. Especially for the flange seals of the nozzles on the top, the traditional reagent application is particularly difficult. Inspectors often have to lie on the container with a traditional sprayer to apply the reagent. It is very difficult to apply the reagent to the nozzles in places with inconvenient positions, such as the nozzles close to the wall or the guardrail. Due to the uneven application and the parts where the reagent cannot be applied, it often causes missed inspection in the airtightness test, which in turn affects the inspection quality and leaves a very large potential safety hazard.

[0003] Therefore, the defects of the existing technology are as follows: (1) It is easy to apply the airtightness reagent unevenly with a sprayer, and it is impossible to apply the reagent in some cases, which affects the detection efficiency and quality of the airtightness test and leaves a potential safety hazard for the container. (2) Applying the traditional airtightness test reagent requires a separate person. For places with inconvenient positions, it is necessary to lie on the stomach to apply the reagent, which makes the inspectors very hard and also increases the safety risk of the inspection.

[0004] The information disclosed in this background art section is only for increasing the understanding of the overall background of the present utility model, and should not be regarded as an admission or any form of suggestion that this information has constituted the prior art known to those of ordinary skill in the art.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1:

[0028] The invention discloses an auxiliary tool for applying reagents for a horizontal container air tightness test, comprising a nozzle 1 made of hard material, a reagent water tank 2, and a water pipe 3; the reagent water tank 2 is connected to one end of the water pipe 3, and the other end of the water pipe 3 is connected to the nozzle 1; the top end of the nozzle 1 is bent; the top of the reagent water tank 2 is connected to a pressurizing device 4.

[0029] In this embodiment, the middle section of the nozzle 1 is a telescopic pipe. The telescopic pipe can be connected to the middle section of the nozzle 1 in the form of an existing telescopic pipe. It can also achieve the change of the final length of the nozzle 1 by adjusting the position between the first branch pipe 11 and the second branch pipe 12. As in this embodiment, the nozzle 1 includes a first branch pipe 11 and a second branch pipe 12. The bottom end of the first branch pipe 11 is inserted into the top end of the second branch pipe 12 to achieve connection. A sealing ring is connected between the first branch pipe 11 and the second branch pipe 12. The sealing ring can achieve the seal between the two to prevent reagent leakage, and can also increase the friction between the first branch pipe 11 and the second branch pipe 12 to achieve the adjustment of the depth of the first branch pipe 11 inserted into the second branch pipe 12.

[0030] In addition to the method of this embodiment, it can also be that the bottom of the first branch pipe 11 is provided with an external thread, and the inside of the second branch pipe 12 is provided with an internal thread. By adjusting the length of the threaded connection, the length of the nozzle 1 can be adjusted to meet the needs of different heights and different space sizes. The threaded connection method can also adjust the spraying direction of the end of the first branch pipe 11.

[0031] The telescopic setting can be in multiple segments. The first branch pipe 11 and the second branch pipe 12 are not limited to straight pipes, and can also be set as pipes with arcs or angles according to the actual use situation.

[0032] In this embodiment, the top of the first branch pipe 11 is bent 90 degrees to change the flow direction of the reagent. The bottom end of the second branch pipe 12 is bent to one side for easy holding.

[0033] The end of the first branch pipe 11 is connected to a nozzle. The nozzle can be formed by reducing the diameter of the nozzle 1. As in this embodiment, the first branch pipe 11 is a stainless steel seamless steel pipe with an outer diameter of 20 mm and a thickness of 5 mm, and the end is a nozzle with an outer diameter of 8 mm. The smaller outer diameter of the nozzle can penetrate into smaller spaces or gaps. The nozzle can also be a nozzle threadedly connected to the end of the nozzle 1. The nozzle can be an atomizing nozzle or other nozzles to make the sprayed reagent more uniform.

[0034] A flow rate controller 5 is connected to the nozzle 1 to achieve the control of the flow rate.

[0035] The pressurizing device 4 is a bicycle pump. The air outlet end of the bicycle pump extends into the reagent water tank 2, and the reagent is pressed from the reagent water tank 2 into the water pipe 3 and the nozzle 1 through air pressure. The structure is simple and easy to use.

[0036] In this embodiment, the water pipe 3 and the nozzle 1 can be connected through a pipe joint, and the water pipe 3 and the reagent water tank 2 can also be connected through a pipe joint.

[0037] When the present embodiment is used, the length and expansion direction of the nozzle 1 are adjusted according to the height of the user and the position where the reagent needs to be sprayed. The bottom of the nozzle 1 is held in the hand, and the top of the nozzle 1 reaches the flange cover at the top of the horizontal container. The nozzle 1 extends the path of the spray reagent. The reagent water tank 2 sprays the reagent onto the flange of the horizontal container through the water pipe 3 and the nozzle 1 through the pressure device 4; the nozzle 1 can also be deeply inserted into the pipe near the wall, the pipe near the position of the guardrail and other positions with smaller space to spray the reagent. Then, the size of the reagent flow rate is adjusted according to the needs of the on-site inspection. Generally, the inspector can accurately make the nozzle enter the flange seal of the pipe (the spacing of the flange seal of the pipe is generally greater than 10mm) whether the nozzle is upward or downward, and the reagent is applied. The inspector can complete the reagent application of the entire pipe sealing surface by turning the body or adjusting the nozzle angle. The top of the nozzle 1 is bent and connected by a soft water pipe 3, all for improving the flexibility of the nozzle 1.

[0038] This embodiment allows the nozzle to accurately enter the sealing part of the pipe flange to apply the reagent. The inspector turns his body and the nozzle 1 can complete the application of the reagent on the entire pipe sealing surface. The structure is simple and the operation is convenient.

[0039] Embodiment 2:

[0040] In this embodiment, the middle section of the spray pipe 1 is connected by a gooseneck tube. Whether it is a telescopic tube or a gooseneck tube, or a segmented setting, it can meet the spraying requirements of people of different heights and different angles to a certain extent, and is more flexible to use.

[0041] The above embodiment is a 100 cubic meter liquefied petroleum gas horizontal storage tank at a gas station in a certain city. The horizontal container is 2 meters above the ground. There are 6 pipes and 2 manhole flange covers on the top of the container. In addition, pedestrian walkways are laid on both sides of the top pipe. The height of the man-shaped steel surface reaches 100 mm, which is just at the position of the high neck flange of the pipe. When conducting an air tightness test, it takes 40 minutes to apply the reagent with a traditional spray pot, and many positions are unevenly applied, which affects the detection quality of the air tightness test. In this case, after using this new patent, the inspector adjusts the telescopic spray pipe 1 to a position that is convenient for application, and then turns the body to apply 360 degrees continuously to each pipe flange position, and it takes a total of 12 minutes to complete the application. The detection quality and detection continuity are improved, and the detection speed is also improved. The same horizontal container is detected 20 to 30 minutes faster after using this patent, which is convenient for the production and operation of the enterprise, directly saves costs for the enterprise, and also escorts the safe use of the equipment.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
