Description
Technical field
The utility model relates to the technical field of measurement and test of valve leak point.
Background technology
Conventionally, pipeline valve at the construction field (site) before installing and using all needs its sealing to detect, accomplish that " zero " leaks, because if in use there is leakage phenomenon, now again change valve just more loaded down with trivial details, keep in repair also more difficultly, conventionally need to spend more human and material resources.The main Types of valve leak is divided into and leaks outside and interior leakage, and generally more difficult discovery of the interior leakage of valve but produces significant impact to the safe operation of valve, easily cause the serious accident of burst, as contaminated in actuating medium, some fire explosion, intoxication accident are all caused by valves leakage.
The detection of valve leakage still lacks effective means, relies on people's sense organ and experience more, and judgement gets up to lack the foundation of science, and error in judgement rate is high.The patent of invention of being declared by Zhangjiagang chemical machinery incorporated company for 2012, application publication number is that CN 102426080 A have announced a kind of valve internal leakage detection tooling, the patent of invention of being declared by Dezhou Golden Elephant non-ferrous metals casting company limited for 2013, Granted publication number discloses a kind of pick-up unit with clamping device for CN 203349997 U, all can be used to detect the leakage situation of valve arrangement, but these two kinds of leak test plants are made more loaded down with trivial details, operation takes up room larger, carrying inconvenience.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of simple and compact for structure, convenient to operation, detect accurate and visual, carry valve leakage detection apparatus easy to carry.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of valve leakage detection apparatus, comprise left chamber, right chamber and tensimeter, described tensimeter is connected with left chamber, described left chamber is equipped with the open end of right chamber the Hermetical connecting structure being connected with valve to be hunted leak, described left chamber is provided with draft tube, right chamber is provided with escape pipe, and described draft tube is provided with gas admittance valve, and escape pipe is provided with air outlet valve.
Preferably, described tensimeter is located in the draft tube between gas admittance valve and left chamber.
Preferably, described Hermetical connecting structure is flange connection, comprises the flange and the retention mechanism that coordinate with valve to be hunted leak that are arranged on left chamber and the open end of right chamber.
Preferably, described retention mechanism is bolt pair.
The beneficial effect that adopts technique scheme to produce is: by being connected with valve to be hunted leak is sealed at both ends of left chamber and right chamber open end, draft tube is connected with pressurized air, in valve, inflate, by observing manometric numerical value change, detect valve and whether have leakage, under the state of closing at valve open to be hunted leak, air outlet valve, tensimeter numerical value declines, and proves that valve housing has leakage; Under the state of opening at valve closing to be hunted leak, air outlet valve, the decline of tensimeter numerical value, proves that valve leaks in existing, otherwise tensimeter numerical value remains unchanged, proof nothing is leaked.The utlity model has simple and compact for structure, convenient to operation, detect accurate and visual, carry advantage easy to carry, handled easily personnel detect the leakproofness of valve at the construction field (site), avoided valve in follow-up use procedure to occur leakage situation, there is the phenomenon that maintain and replace is difficult, delay production, can reduce labor intensity of operating staff, increase work efficiency and construction quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model;
In figure: 1-left chamber, 2-draft tube, 3-gas admittance valve, 4-tensimeter, 5-flange, 6-valve, 7-bolt pair, 8-air outlet valve, 9-escape pipe, the right chamber of 10-.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of valve leakage detection apparatus as shown in Figure 1, comprise left chamber 1, right chamber 10 and tensimeter 4, described tensimeter 4 is connected with left chamber 1, described left chamber 1 is equipped with the open end of right chamber 10 Hermetical connecting structure being connected with valve 6 to be hunted leak, described left chamber 1 is provided with draft tube 2, right chamber 10 is provided with escape pipe 9, described draft tube 2 is provided with gas admittance valve 3, escape pipe 9 is provided with air outlet valve 8, described tensimeter 4 is located in the draft tube 2 between gas admittance valve 3 and left chamber 1, described Hermetical connecting structure can be flange connection, comprise the flange 5 and the retention mechanism that coordinate with valve 6 to be hunted leak that are arranged on left chamber 1 and the open end of right chamber 10, described retention mechanism is bolt pair 7, utilize bolt pair 7 that left chamber 1 is fixed together with valve 6 to be hunted leak with right chamber 10.
During concrete enforcement, the flange 5 of left chamber 1 and right chamber 10 open ends is connected to valve to be hunted leak 6 two ends, draft tube 2 is connected with pressurized air, toward the interior inflation of valve 6, until tensimeter 4 pointers, point to while requiring numerical value, close gas admittance valve 3, by observing the numerical value change of tensimeter 4, detect valve 6 and whether have leakage.It is under the state that valve 6 to be hunted leak is opened, air outlet valve 8 cuts out that detection leaks outside, if tensimeter 4 numerical value decline, proves that valve 6 housings have leak source; In detecting, leaking is under the state that valve 6 to be hunted leak is closed, air outlet valve 8 is opened, if tensimeter 4 numerical value decline, prove valve 6 exist in leakage, otherwise tensimeter 4 numerical value remain unchanged and prove without leak source.
When detection leaks outside, also can as valve 6 housings have bubble outward, occur in the peripheral spraying one deck of valve 6 to be hunted leak test fluid, prove that valve 6 housings have leak source, otherwise without leak source; While leaking in detection, in escape pipe 9 mouths of pipe spraying test fluid, the mouth of pipe occurs if any bubble, proves the interior leakage of valve 6, on the contrary the not interior leakage of valve 6.
It is more than a preferred embodiment of the present utility model, tensimeter 4 also can be arranged on left chamber's 1 outer wall, left chamber 1 is different and different according to the import and export syndeton of valve 6 with the syndeton of valve 6 to be hunted leak from right chamber 10, if the import and export of valve 6 are screwed connection mode, left chamber 1 can adopt screw thread pipe fitting joint structure with right chamber 10 and the syndeton of valve 6 to be hunted leak; In addition, left chamber 1 also can other fastening means be fixed with right chamber 10 and the connected mode of valve 6 to be hunted leak, as adopted the U-shaped buckle of strap bolt pin fastening.
In sum, utilize the utility model can detect quickly valve 6 and whether have leakage, along with the convenient transfer of construction site is carried transportation, the utlity model has simple and compact for structure, convenient to operation, detect accurate and visual, carry advantage easy to carry, handled easily personnel detect the leakproofness of valve at the construction field (site) in advance, as find valve leak, can place under repair in time or change, avoided valve in follow-up use procedure to occur leakage situation, there is maintain and replace difficulty, the phenomenon that delays production, reduced labor intensity of operating staff, increase work efficiency and construction quality.
