Description
Technical field
The utility model relates to a kind of plug, particularly relates to the automatic swelling plug of a kind of heating radiator air-leakage test.
Background technology
Detect heating radiator sealing property by leak detector, need sealed heat-dissipating device intake-outlet, now use polyurethane taper plug, by manpower by plug and heating radiator intake-outlet jam-pack, thus play the effect of sealing.There is following shortcoming: 1. by manpower by plug jam-pack, take time and effort, manipulation strength is large, and efficiency is low; 2. human factor is large, and plug reliability is not high, and airtight detector precision is very high, often reports to the police because of plug tiny leaks, thus can occur erroneous judgement to product hermeticity, causes waste.
Summary of the invention
The purpose of this utility model is the deficiency existed for prior art, and provide a kind of easy and simple to handle, impermeability is good, and sealing is reliable, the automatic swelling plug of the heating radiator air-leakage test that detection efficiency is high.
For achieving the above object, the technical scheme that the automatic swelling plug of the utility model heating radiator air-leakage test adopts is:
The automatic swelling plug of a kind of heating radiator air-leakage test, comprise the cylinder closed one end and the piston coordinated with cylinder, described cylinder comprises the diapire of cylinder body and closed cylinder, described piston is connected with cylinder seal, diapire is provided with through hole, piston is provided with the boss running through through hole, boss and through hole are tightly connected, resilient sleeve is socketed with in the outside of boss, the end of boss is provided with the step limiting resilient sleeve and move axially, described piston is provided with the first air admission hole be subjected to displacement between driven plunger and cylinder, and the first air admission hole is facing to the diapire of cylinder.
Described boss is provided with the second air admission hole inflated in heating radiator, and the second air admission hole runs through boss and piston.
The sidewall of described piston is provided with the piston ring sealed with cylinder block.
The inwall of described through hole is provided with the O-ring seal sealed with boss.
Described resilient sleeve is rubber sleeve.
The step that boss end is arranged is the end cap be connected with boss, and the middle part of end cap is provided with the center pit communicated with the second air admission hole.
Described piston ring is O-ring seal.
The utility model compared with prior art, has the following advantages:
Resilient sleeve is inserted water inlet or the water delivering orifice of heating radiator, pressed gas is passed into the first air admission hole, piston driving boss moves up, resilient sleeve shortens to length under the drive of boss, external diameter is thicker to be blocked the water inlet of heating radiator or water delivering orifice, achieves quick blocking water inlet or water delivering orifice, easy and simple to handle, sealing is reliable, improves detection efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the automatic swelling plug of heating radiator air-leakage test.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1, the automatic swelling plug of a kind of heating radiator air-leakage test comprises the cylinder 1 closed one end and the piston 2 being arranged on cylinder interior, this cylinder comprises the diapire 12 of columned cylinder body 11 and closed cylinder, this diapire is provided with through hole 13, piston is provided with the columniform boss 21 running through through hole, the medial surface of through hole 13 is provided with O-ring seal 14, gap between O-ring seal 14 seal boss and through hole, the outside of boss is socketed with rubber sleeve 3, rubber sleeve 3 is limited between the end cap 22 of diapire and boss end, and end cap is threaded with boss.The outer peripheral face interlocking of piston has O-ring seal 23, the gap between O-ring seal 23 packed-piston and inboard wall of cylinder block.Piston offers the first air admission hole 24 be subjected to displacement between driven plunger and cylinder, first air admission hole 24 is facing to the diapire of cylinder, boss offers the second air admission hole 25 inflated in heating radiator, second air admission hole 25 runs through boss and piston, end cap offers the center pit communicated with the second air admission hole, and end cap and boss are threaded connection.
Principle of work: by joint, the second air admission hole and air-leakage detector are detected gas circuit and connect, the first air admission hole connects with expansion gas circuit, and the internal diameter according to water inlet of radiator or water delivering orifice selects rubber sleeve.During work, inserted by rubber sleeve into intake-outlet, press device button, the first air admission hole ventilation, the relative cylinder of piston moves upward, and boss drives end cap compressing rubber cover, and rubber sleeve closely engages with water inlet or water delivering orifice inwall, reaches sealing function.Second air admission hole ventilation starts air-leakage test, the first air admission hole automatic vent after having detected, and piston playbacks, and is taken out by plug, fulfils assignment.
