Description
Technical field
The utility model relates to a kind of proving installation that valve member is carried out the impermeability test of withstand voltage and flap and valve rod.
Background technology
In the installation work of various metallic conduits, will be referred to method indigo plant, valve member structural member that plurality of specifications and diameter do not wait.According to designing requirement, normal water one by one or other medium carry out the impermeability test of withstand voltage test and flap and valve rod before valve is installed.By the convention of present working-yard, need one by one after the valve two ends install the shutoff blind plate additional and tighten with bolt, to carry out pressure test again.In this way large batch of valve member is tested one by one, obviously efficient is low, influences project progress, and operating personnel's working strength is big, and expends a large amount of labours, increases engineering cost.
The utility model content
At above-mentioned situation, the utility model will provide a kind of proving installation that is used for valve member, to address the above problem.
Valve test device of the present utility model has the position limiting structure of a tool accommodation space in the structure, at the place, both sides that can match with the two-port of tested valve, be respectively arranged with press water perfusion unit and telescopic shutoff unit in this accommodation space.In the said press water perfusion unit, include a closed pressure water injection case through the mouth of a river and pressure water source system connectivity, its with end face structure that tested valve port contacts on be provided with a pressure flow through passage; In the said telescopic shutoff unit, comprise a plugging structure that can match and have on it able to turn on or off exhausr port with tested valve another port and, be arranged at the telescopic roof pressure structure between itself and the position limiting structure.
When the utility model said structure form valve test device carries out pressure test to valve member, only need and to be tried between the accommodation space press water perfusion unit and telescopic shutoff unit that valve member places this position limiting structure by side, make the inlet end of valve member be matched with the pressure flow of the said end face structure of this pressure water injection case in the press water perfusion unit through the access site place, endpiece is matched with the plugging structure place in the telescopic shutoff unit, and after by the telescopic roof pressure structure pressurization of in the telescopic shutoff unit this its two-port being closed, pressure water source system by being provided with accessory structures such as forcing pump and tensimeter will meet pressure (hydraulic) water that test pressure requires through the pressure water injection case and be filled in the valve (in the valve air can by the able to turn on or off exhausr port discharging on this plugging structure) by the inlet end of tested valve member, can by institute accordingly rules carry out the test of required test event.
Based on this, the position limiting structure of said this tool accommodation space in the above-mentioned proving installation of the utility model, help in process of the test, keeping stablizing under institute's pressure state that bears satisfying, and conveniently under the situation about picking and placeing to tested valve member, generally adopt various forms of tower structures to get final product.
Leakage for the pressure (hydraulic) water avoiding being poured in the valve in the test process, the corresponding contact mating surface place that can contact with the port of tested valve in said this pressure water injection case and/or this plugging structure and cooperate, the elastic construction layer that has sealing function with the rubber that is coated with suitable thickness, plastic cement etc. is good.
Because the pressure (hydraulic) water to the valve member test pours into through said this pressure water injection case, therefore in this pressure water injection case, also can be provided with perisporium as required and strengthen structure, improve its reliability and security.
Said telescopic roof pressure structure is generally convenient to realize by the flexible roof pressure structure as common lifting jack forms such as spiral or fluid pressure type in the said structure.
For further facilitating test operation, particularly convenient to the loading or unloading operation in the large-scale valve member test, on the basis of said structure form, can also adopt said this pressure water injection case is arranged at the suitable structural form of removable support.
Be appreciated that the valve test device of the utility model said structure form thus, be very easy to testing experiment, particularly the testing experiment that valve member in enormous quantities is carried out one by one valve member.Compare with traditional approach, adopt the utility model device to test, can improve work efficiency more than 70%, and alleviate the labour intensity of testing crew.
Below in conjunction with the embodiment of accompanying drawing illustrated embodiment, foregoing of the present utility model is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
