Description
Technical field
The utility model belongs to pick-up unit field, especially relevant with a kind of coil pipe air-tightness detection device.
Background technology
Air-leakage test is needed after coil pipe machines, detect coil pipe whether to leak gas, be vented phenomenons such as having some setbacks, good being tightly connected is needed at the air-leakage test hour indicator mouth of pipe and high voltage interface, coil pipe needs to bear high-pressure medium circulation, air-leakage test is carried out to coil pipe, needs to connect high-pressure air source during inflation and to be connected with metal dish tube cavity device, because metal dish thickness of pipe is thinner, easily sustaining damage during connection, causing when detecting impermeability unstable.
Utility model content
The purpose of this utility model is exactly to solve the defect easily sustained damage when high-pressure air source is connected with metal coil pipe, provides a kind of easy for installation, the simple coil pipe air-tightness detection device of structure that connect between coil pipe and high-pressure air source.
For this reason, the utility model is by the following technical solutions: coil pipe air-tightness detection device, it is characterized in that, described pick-up unit comprises anchor ear cover, neck bush and end cap, the body that anchor ear cover is split vertically by two, the radial involutory screw that is combined through of body connects, described anchor ear cover is set in coil pipe external diameter makes anchor ear cover internal diameter and coil pipe external diameter closely cooperate, described end cap is fixedly connected on anchor ear by screw and overlaps one end, described end cap arranges central through hole, described neck bush comprises annular body, one end end face of annular body is provided with center axial projection, annular body is flush-mounted in described coil pipe, annular body is resisted against on the inner side end of described end cap, the periphery of annular body is provided with at least one annular groove, be embedded with O-ring seal in annular groove to make to play sealing between the external wall of annular sleeve and coil pipe inwall, described axial projection is stretched out from the central through hole of described end cap, axial projection is provided with axially inflation through hole and is communicated with annular sleeve intracoelomic cavity, neck bush is spacing by end cap, the aperture place of described inflation through hole front end is fitted with a gas filling valve.
As to technique scheme supplement and perfect, the utility model also comprises following technical characteristic.
The internal diameter of the inflation through hole of described neck bush is by the annular body side internal diameter axially staged expansion of neck bush front end to neck bush, and available buffer air-flow reduces the impulsive force of air-flow.
Described anchor ear cover periphery arranges venting valve opening, and described venting valve opening is for placing the air release on coil pipe.
The utility model can reach following beneficial effect: metal coil pipe is connected with the joint of high-pressure air source by this device, the radial involutory external diameter being set in coil pipe of anchor ear cover fits tightly, high-pressure air source in the process of inflation impermeability better, easy accessibility and structure simple.
