Description
Technical field
This utility model relates to a kind of test device for air tightness, particularly a kind of steel and moulds the air tightness test machine of conversion pipe fitting.
Background technology
When the conveyance conduit of natural gas is laid, the connectivity problem being frequently encountered steel pipe and mould pipe, the transition as two kinds of materials of the conversion pipe fitting moulded by steel, special installation and technique is utilized to be coupled together with moulding pipe by steel pipe, the tubing of two kinds of unlike materials carries out overlapping combination in port, remaining two ports respectively with steel pipe or mould pipe and carry out the connection of same material, steel is moulded conversion pipe fitting and is divided into two kinds intuitively, one is that conversion pipe fitting moulded by straight tube steel, one is that conversion pipe fitting moulded by 90 degree of bent angle steel, steel pipe with mould pipe overlapping interface position because being the interference fit coupling part of two kinds of unlike materials, owing to the coefficient of expansion of unlike material is different, there is the probability of poorly sealed gas leakage in theory, when the pipeline connected has the natural gas of certain pressure to pass through, if it is poorly sealed, the gas of seepage can cause security incident.
At present, the air tightness test of conversion pipe fitting moulded by known steel two ways, the first is that steel is moulded conversion pipe fitting clamping on equipment, but do not have what water circulated to put, after steel plastic pipe is by hydraulic pressure or the closure of cylinder two ends, one end wherein passes into test gas, liquid soap is coated now by moulding overlapping interface position hairbrush at steel, see whether that bubble occurs, there is subregion leakage brush and be difficult to stop for a long time aloft with fluid itself in this kind of method, cause the soap film that cannot form all standing, thus producing detection leakage phenomenon, in order to exempt from the generation of missing inspection, the mode smeared only by multipass and uninterruptedly smear is to guarantee the effect of detection, this kind of mode detects not only inefficiency, and it is seriously polluted, it is difficult to accomplish the requirement that cleaning produces, additionally, due to being artificial proportioning soap lye, matched proportion density is directly influenced to the effect of foaming, so anthropic factor is too many on the impact of test effect.
The second is to utilize special fixture steel loading to mould the closure of conversion pipe fitting two ends in outside, and at one end pass into test gas, ready steel is moulded conversion pipe fitting by manual operation or lifting arm, put into the test container being filled with water, bubble-free produces at the appointed time, it is then certified products, this kind of method of testing is extremely inefficient, additionally the labor intensity of operator is big, simultaneously the installation of fixture is because part needs and moulds pipe and overlap, so be easier to damage the surface of surface and the steel pipe moulding pipe, thus cause secondary product quality problem.
Summary of the invention
Technical problem to be solved in the utility model is: how to solve conventional steel and moulds the defect existed in the test process of conversion pipe fitting.
This utility model be the technical scheme is that the air tightness test machine of conversion pipe fitting moulded by a kind of steel, including frame, what be connected with the first hydraulic jack moulds conversion pipe fitting one end or the first flange changing pipe fitting one end moulded by 90 degree bent angle steel for connecting short straight steel, the second flange moulding conversion pipe fitting one end for connecting long straight steel being connected with the second hydraulic jack, the three-flange moulding the conversion pipe fitting other end for connecting 90 degree of bent angle steel being connected with the 3rd hydraulic jack, connect short straight steel and mould the first closure plate of the conversion pipe fitting other end, connect long straight steel and mould the second closure plate of the conversion pipe fitting other end, air compressor machine, Pressure gauge, programmable logic controller (PLC), testing flume, water circulating pump, water tank, control panel, first flange and the first closure plate are corresponding in level, second flange and the second closure plate are corresponding on vertically, first flange and the second flange connect air compressor machine by Pressure gauge pipeline, inspection groove is connected with water tank by water circulating pump.
As a kind of optimal way: also include the extension adjustment device for regulating length being arranged on both sides, testing flume upper end, the with holes lower steel pipe of upper steel pipe, the bolt through upper steel pipe and lower steel pipe hole for connecting are inserted in upper steel pipe with holes, one end that extension adjustment device includes being arranged on the top board of frame.
As a kind of optimal way: also include moulding conversion pipe fitting or 90 degree bent angle steel are moulded telescopic first backing plate of conversion pipe fitting, moulded conversion pipe fitting or telescopic second backing plate changing pipe fitting moulded by 90 degree of bent angle steel for supporting long straight steel for supporting short straight steel.
As a kind of optimal way: there is the condensate tank of dehumidifier being connected with programmable logic controller (PLC) inside testing flume.
As a kind of optimal way: the import of testing flume has defecator, has water discharging valve with the groove of testing flume.
The beneficial effects of the utility model are: conversion pipe fitting moulded by straight tube steel by this utility model and 90 degree of bend pipe steel are moulded the pipe fitting test changing two kinds of different patterns of pipe fitting and focused on an equipment, simultaneously in order to adapt to the product specification of more different length, upper and lower steel pipe of the present utility model is telescopically adjustable structure, this utility model has installed circulating water device and separate multistation test function additional, this utility model utilizes programmable logic controller (PLC), improve the degree of automatization, improve detection efficiency, alleviate labor intensity, eliminate the anthropic factor impact on test result, this utility model can concentrate the test event of the different durations of the two kinds of different air pressure required in two kinds of national standards on a machine, this utility model has installed the recirculated water guiding device of Circulated water filter and hommization additional.
