When the fire extinguishing agent bottle(1) is put into a pool, leakage can be observed through reading of the meter(4). The utility model is simple in structure, easy in handling, low in manufacturing cost and can qualitatively and quantitatively detect of leakage of the fire extinguishing agent groups.

Description

The leakage detection apparatus of extinguishing agent bottle group

Technical field

The utility model relates to the leakage detection apparatus of extinguishing agent bottle group, belongs to fire-protection equipment detection device.

Background technique

At present, the inert gas fire-fighting system that domestic manufacturer produces, its critical piece---extinguishing agent bottle group, traditional leak hunting method is that extinguishing agent bottle group is put into the pond by observing the qualitative leak detection of bubble.The shortcoming of this traditional leak hunting method is: (1), extinguishing agent bottle group need be placed in the swimmer's pool with the perusal leak detection, do not have the quantitative statistics device; (2), owing to have higher pressure difference inside and outside the bottle, guarantee to store bottle and leak anything but and be difficult to accomplish; (3), the not equal personal factor of the small and observing angle of bubble can cause error in judgement; (4), micro-leakage is difficult to detect, and causes legal dispute.

Domestic bigger fire extinguisher factory once adopted portable induction detector to breathing out fire extinguishers such as dragon, can send " toots " in the time of detecting certain position of bottle group leak by strafing and call, and can make needle of instrument deflection, the size of qualitative reflection leakage rate.Be characterized in: easy to operate, laborsaving, cost is low, suitable batch production, but can only qualitatively reflect, can not be quantitative; And the position shows one by one, can't accurately add up the leakage total amount.

It is reported, abroad some companies are on the performing leak test operation of fire extinguisher production line, adopt the whole sealing cover of fire extinguisher is lived, vacuumized, and regularly collect leakage and carry out quantitative detection method by instrument.Its characteristics: method is rationally advanced, but the technology cost is higher, is applicable to less containers such as fire extinguisher.As the single bottle group of suppression system because bottle group volume is big, seal, vacuum and carry out difficulty such as instrument analysis and cost all higher, be not suitable for the present situation of domestic production.

For the tightness of bottle group, stipulated in Ministry of Public Security's industry standard that bottle is organized the immersed in liquid level degree of depth to be not less than in the 0.3m water, the bottle group should not have bubble and leaks.The UL2127 standard code: MANUFACTURER should be tested each complete vessel valve system unit, and leak-down rate should not surpass 0.139% each year of extinguishing agent total amount.

The inventor's practical experience is thought: the leakage of general extinguishing agent bottle group mostly occurs in being connected of cylinder valve and bottle and valve and fills sealing behind the extinguishing agent or sealing surface and have that foul causes, so the leakage that bottle is organized mainly is at the bottle head.Catch this principal contradiction, just much more simply the processing of bottle group Leak testtion problem.The inventor also thinks: the requirement that proposes year leak-down rate more science, more meet objective reality, problem is that the method that how leakage rate is quantitatively detected and detects is the key of dealing with problems.

Summary of the invention

The purpose of this utility model is intended to solve prior art problems, design the leakage detection apparatus of the extinguishing agent bottle group of measurable statistics leakage rate, it have simple in structure, easy to use, low cost of manufacture, not only can be qualitative but also can quantitatively detect the device of the leakage situation of extinguishing agent bottle group.

For this reason, the technical solution adopted in the utility model one is: a metering mechanism (4) is directly installed on the top in the extinguishing agent bottle group (1) that stands vertically; Extinguishing agent bottle group (1) is placed in the pond, grasps leakage rate by the reading of observing on the metering mechanism (4).Perhaps carrying out improved plan two according to technological scheme one is: the metering mechanism (4) that will be located at extinguishing agent bottle group (1) top is drawn the reading of observing on the metering mechanism (4) in the pond by a water pipe and is grasped leakage rate.

The technical solution of the utility model three is: making one and can cover cylinder valve and cylinder valve and being filled with water of connection part of bottle group used trap, specifically is to be provided with a trap on the extinguishing agent bottle group top that stands vertically, and trap comprises cover body, water intake and gauge table.The connection part of cover body and extinguishing agent bottle group need seal up.The method of measurement of this device is: with trap cover body filled with water (the inside air must drain), cover cylinder valve and bottleneck connection part.After a period of time, just can record the leakage tolerance of collection.Measuring accuracy increases with measurement time and improves.

Embodiment:

Further describe the utility model below in conjunction with drawings and the specific embodiments.

The leakage detection apparatus of a kind of extinguishing agent bottle group of the present utility model is at the upper vertical installing metering mechanism 4 of the extinguishing agent bottle group 1 that stands vertically.After being placed on extinguishing agent bottle group 1 in the pond 10, can grasp leakage rate by the reading of observing on the metering mechanism 4.Also can be as shown in Figure 2, organize the metering mechanism 4 on 1 top and draw the reading of observing on the metering mechanism 4 in the pond by a water pipe 11 and grasp leakage rate being located at the extinguishing agent bottle.

The leakage detection apparatus of second kind of extinguishing agent bottle group of the present utility model is to organize 1 top at the extinguishing agent bottle that stands vertically to be provided with a water containing trap 2.Trap 2 comprises cover body 3, is provided with metering mechanism 4 on the top of cover body 3, and metering mechanism 4 communicates with cover body 3.Described metering mechanism 4 is the transparent meter device of milliliter (ml) scale value, and the top of metering mechanism 4 is provided with venting stifled 9.The proportion of whole trap 2 should be greater than water.Cover body 3 can be inverted U type/ball-type or other cavity body.Be provided with O RunddichtringO 8 at a cover body 3 and bottle connection part of group 1, the connection part of cover body 3 with bottle group 1 can be sealed.Below cover body 3, be provided with water intake 5, water intake 5 external intake pipes 6.Described intake pipe 6 can be made flexible pipe or adjustable pipe.During use, cover body 3 seals with the connection part of bottle group 1, and need drain air.Fills with water in cover body 3 just can record the leakage tolerance of collection after a period of time.

The utility model is tested through the inventor, and has designed the quantitative leak computational methods of a cover leakage rate.Detection during with 20 ℃ in 70L, 15Mpa level storage bottle is an example, and 0.139% is foundation with the year limit leak-down rate of UL2127 standard code, and calculate: per hour leakage rate is 1.65 cubic centimetres.

The advantages such as quantitative leak device of the present utility model has simply, easily row, running cost be low have very Good market popularization value.
