Description
Technical field
A kind of groove pipe fitting quality detection apparatus is the utility model is related to, specifically a kind of threeway groove pipe fitting is airtight
Property detection device.
Background technology
Groove pipe fitting is a kind of conduit coupling, main to play connection transitional function, and groove pipe fitting mainly includes threeway groove
Pipe fitting, elbow groove pipe fitting, reducing fittings etc., the groove pipe fitting described by the utility model is primarily referred to as conventional threeway groove
Pipe fitting.
There are various ways to carry out air-leakage test, conventional method to common pipeline or pipe-line system in the prior art
It is to utilize pulsometer punching press into pipeline, judges the air-tightness of pipe-line system or pipeline, this method by measuring atmospheric pressure value
The advantages of be it is fairly simple directly but the equipment employed is more, cost is higher, and this method is relatively specific for larger
And pipeline slight crack or the obvious pipeline of leak, due to threeway groove pipe fitting small volume, and pipeline slight crack or leak are not
Substantially, if still utilizing the method for punching press, because air pressure crosses conference so that slight crack aggravates, simultaneously as air pressure is rushed in big, split
Lacking for trace leakage, can to have been at high pressure conditions inside pipeline, the unobvious that air pressure reduces, moreover, the side for passing through punching press
Method testing cost is higher, and inapplicable threeway groove pipe fitting.
Utility model content
In view of the above-mentioned problems, the utility model proposes a kind of threeway groove pipe fitting air tightness detection equipment, it is above-mentioned to solve
Existing technical problem.
Specifically scheme is：A kind of threeway groove pipe fitting air tightness detection equipment, the equipment include monitor station, and monitor station is left
Side is provided with the fixed mount for fixing threeway groove pipe fitting, is provided with heater below fixed mount, heater is hot blast
Other can discharge the heat resource equipment of heat to mechanical, electrical hot stove etc., and stylobate is provided with the right side of heater, Sheng is placed with the top of stylobate
Water receptacle, the container side wall of water container is transparent plastics or glass material, facilitates inspection personnel to observe；
The equipment also includes being used for the air-tightness mechanism for controlling gas to flow, and the air-tightness mechanism includes main flexible tube, main
Flexible pipe one end is deep into water container, and the main flexible tube other end is arranged with three branch flexible pipes, three branch flexible pipes and main flexible tube UNICOM,
Branch hose end described in every runs through the sealing-plug being fixed with for blocking the threeway groove pipe fitting mouth of pipe.Fixed mount is by three thorough cuts
Barrel part is fixed, and is then blocked the mouth of pipe of threeway groove pipe fitting by sealing-plug, now threeway groove inside pipe fitting belongs to close
Closed state, heater start to heat threeway groove pipe fitting, according to the principle expanded with heat and contract with cold, gas in threeway groove pipe fitting
Body expanded by heating, air pressure rise, now, if threeway groove air tightness of pipe fitting does not have slight crack well, air pressure can pass through branch flexible pipe
Main flexible tube is aggregated into, then by being discharged at the termination mouth of pipe of main flexible tube, can now observe in water container has bubble to emerge；
If threeway groove pipe fitting has slight crack, air pressure can be discharged by slight crack, can now observe in water container bubbles volume very little or
There is no bubble to emerge.
Described main flexible tube and the branch flexible pipe outer layer described in every are enclosed with glass fibre, and glass fibre has good
Heat-insulating property, prevent the heated device of the gas in main flexible tube and branch flexible pipe heat radiation influence and expand, guarantee bubble
Only discharged by the air pressure in threeway groove pipe fitting, strengthen the accuracy of detection.
Check valve is provided with the branch flexible pipe mouth of pipe described in every, the circulating direction that check valve is allowed is：Threeway groove
Pipe fitting flows to branch flexible pipe.The effect of check valve is to prevent in flexible pipe gas backstreaming so as to influence detection accuracy, and three thorough cuts
For gas in barrel part when being passed into branch flexible pipe, check valve can also provide faint resistance to gas, now, if threeway groove
Pipe fitting inner wall is leaky or crack, gas preferred can flow out at leak or crack, without selecting to overcome check valve to be flowed into
In branch flexible pipe, now, main flexible tube termination does not have bubble and emerged, and considerably increases the accuracy of detection.
Described fixed mount includes column, and the column top is fixed with cross bar, and cross bar one end is provided with for fixing three
The caliper of thorough cut barrel part vertical tube.Described caliper is clip, the size of clip and the stack dimensions shape of threeway groove pipe fitting
It is corresponding.
The threaded post being engaged with threeway groove pipe fitting mouth of pipe internal thread, described sealing are provided with described sealing-plug
Plug inner bottom part place mat has sealing rubber pad, and the effect of sealing rubber pad is to strengthen the sealing effectiveness of sealing-plug.
Gas flow control valve is provided with described main flexible tube, is mainly needed to control bubbles volume and tune according to experiment
Pressure control is poor.
Movable sleeve is connected to travelling folder on described main flexible tube, and travelling folder includes a shelf, and a collar is fixed in shelf body, covers
Ring and main flexible tube pivot bush unit, travelling folder can be slided arbitrarily on main flexible tube, for main flexible tube to be fixed.
The specification of described branch flexible pipe caliber is 0.15cm~0.25cm, the orifice area corresponding to the caliber of flexible pipe with absolutely
The area of most of slight crack is close, when threeway groove pipe fitting has slight crack, can effectively reduce what air pressure was discharged by branch flexible pipe
Gas flow, bubbles volume is greatly reduced, add the accuracy of detection, considered according to economy and practicality, preferably
0.20cm pipe diameter size cost performance highest.
The beneficial effects of the utility model are:The application cleverly make use of the physical principle expanded with heat and contract with cold, heater
Threeway groove pipe fitting is heated, when gases are heated, they expand in threeway groove pipe fitting, by observing the bubble in water container water
Situation judges the sealing of threeway groove pipe fitting, has the advantages of operation principle is simple, portable construction, while check valve, glass
Glass fiber and branch flexible pipe caliber specification considerably increase the accuracy of detection.
