Detailed description of the invention
A kind of novel utilidor repaired mouth described in the utility model needs two people to coordinate when sealing the test of shape assay device
Operation.The one stifled steam vent of human hand held solid rubber rod pressure is also responsible for observing Pressure gauge, the stifled note of another human hand held hollow rubber rod pressure
Operation control valve is also responsible in material hole.
A kind of utilidor repaired mouth seal test device, it include the stifled rod 1 of solid rubber, the stifled rod 2 of hollow air inlet rubber, the
One connects flexible pipe 3, threeway element 4, Pressure gauge 5, control valve the 6, second connection flexible pipe 7 and hydraulic quick coupler 8；Hollow air inlet rubber
The stifled rod 2 of glue is connected flexible pipe 3 with threeway element 4 with the first of 500mm length and is connected.Pressure gauge 5 connects with double thread with threeway element 4
Head tube part is connected, and Pressure gauge is closed.Threeway element 4 is connected flexible pipe 7 phase with hydraulic quick coupler 8 with the second of one meter long
Even, the second connection flexible pipe 7 arranging control valve 6, hydraulic quick coupler 8 is connected with air compressor by the 3rd connection flexible pipe, empty
Air compressor is connected with electromotor.Tamper used by described this utility model is a kind of soft rubber rod, and one end is fabricated to
Taper, is beneficial to seal, and one is that solid rubber blocks up rod 1, another root is the stifled rod 2 of hollow air inlet rubber, adhesive rubber flexible pipe, permissible
Conveying gas.Each connecting portion to require to install according to relevant criterion, coupling stiffness and sealing use to be met requirement,
It is 300mm that solid rubber blocks up excellent 1 total height, diameter of phi 50mm, and plug is 120 ° of cone angles, and cone height is 50mm.
When utilidor repaired mouth sealing experimental provision uses at the construction field (site), supporting air compressor 9 need to be equipped with, as
Field construction place does not has power supply, also needs to be equipped with corresponding electromotor 10.These equipment are all common apparatus, according to gas consumption and
System gas pressure requires the electromotor selecting air compressor and matching.All elements all connect intact after, it is possible to open
Dynamic electromotor 10, air compressor 9 supply is tested.Two people press simultaneously the stifled rod of rubber (the stifled rod 1 of solid rubber and hollow enter
The stifled rod 2 of gas rubber) block the sprue on repaired mouth and steam vent, the most slowly open control valve 6 and inflate.When Pressure gauge 5 shows
When value reaches test requirements document force value, and indicating value stable after notify that another people closes control valve 6 pressurize, and start timing.Protect
The indicating value of Pressure gauge 5 is examined with or without declining or checking that the soap liquid spreading upon seam crossing has bubble-free to produce during pressure.As
Pressure gauge 5 indicating value does not has pressure drop or the soap liquid smeared not to produce bubble i.e. to show that the sealing of this repaired mouth reaches requirement,
Slowly unclamp the rubber bar of pressing closure, make gas discharge.It is decreased obviously or smears the soap of seam crossing as Pressure gauge 5 indicating value has
Liquid produces bubble and i.e. shows that repaired mouth exists the place of gas leakage, and sealing is undesirable.Needs repair after the most again by
Test according to above-mentioned steps, until pass the test.
The above, preferably detailed description of the invention the most of the present utility model, but protection domain of the present utility model is also
Being not limited to this, all those familiar with the art are in technical scope disclosed in this utility model, according to this reality
All should contain of the present utility model by novel technical scheme and design of the present utility model thereof in addition equivalent or change
Within protection domain.
The beneficial effect of the present embodiment: height and the diameter dimension of the stifled rod 1 of hollow air inlet rubber are suitable for manually holding, and energy
Use power.120 ° of sprues being easy to repaired mouth of its cone angle or steam vent fitted seal, the conical surface reduces sealing and coordinates contact area,
Be conducive to increasing sealing effectiveness.Rubber bar material selection to select certain rigidity, has enough frictional force with hands when holding,
Feel will be good natural rubber.As hollow air inlet rubber blocks up excellent 2 specifications rod 1 stifled with solid rubber, centre bit is equipped with Φ
12 through holes, test gas enters repaired mouth test space by Φ 12 hole.Special process is passed through in the upper end of the stifled rod 2 of hollow air inlet rubber
Connect the soft rubber trachea of one section of 500mm length, it is ensured that the stifled rod of rubber and trachea bonding strength and sealing.Utilidor is mended
The middle part of mouth sealing experimental provision is the threeway element 4 of a special nylon material, and one end of threeway element 4 connects
The soft rubber tracheas that the stifled rod 2 of hollow air inlet rubber picks out, by this section of 500mm length trachea hollow air inlet rubber is blocked up
Rod 2 is connected with threeway element 4, and ensures the sealing connected.Install on the arm of threeway element 4 range be 0～
The air special pressure table 5 of 0.1MPa, for the force value of detecting system during test.Pressure gauge 5 must be the list through there being qualification
The product that position is qualified, and use before the deadline.The other end of the supervisor of threeway element 4 installs one by connecting pipe fitting
Control valve 6, if control valve 6 also has the most qualified valve that pressure elements produces the manufacturer production of qualification.Adjust
Joint valve 6 controls to stop inflation during size and the pressurize of air inflow in time testing.The other end of control valve 6 is by pipeline even
Connecing element and connect the soft rubber trachea (second connects flexible pipe 7) that a segment length is a meter, the second end connecting flexible pipe 7 is installed
One Quick replacing gas joint 8, for quickly connecting gas source pipe, is connected one complete gas circuit of composition with air supply system.This reality
Being an entirety with 4 hollow air inlet rubber bars 2 of novel employing threeway element, Pressure gauge 5, control valve 6 connection, composition seals
The core component of property assay device.This connection combining form simple in construction, it is easy to operation, work efficiency is high.
