Abstract
It is a kind of quick opening manhole bearing container the utility model is related to arrive harmful influence tank car field.It is characterized in that lower grip tab and upper grip tab, in handle, connecting flange has shell ring to be connected outside lid in connecting flange；There are attachment lug, connection ear mount to be fixed by wing nut outside connection ear mount, connecting in ear mount has eyelet bolt；In casing, connection sheet A, connection sheet B, the both ends connection sheet C are compressed connecting shaft by nut.As a result of the technical program, meeting can use in the operating mode in 0.6MPa, increase the intensity and leakproofness of quick opening manhole；Since using trapezoidal polytetrafluoroethylene (PTFE) cladding pad, service life extends；Structure is highly practical, simple in structure.
Description
Technical field
It is a kind of quick opening manhole bearing container the utility model is related to arrive harmful influence tank car field.
Background technology
The quick opening manhole of tank container application, was operating as defined in existing harmful influence tank car and JB/T4782-2007
When bearing instantaneous pressure in journey, dielectric leakage is often resulted in since sealing is bad, medium could be laid down by increasing operating pressure,
The applying working condition that product design is is changed, harmful influence safety accident is directly contributed.Existing producer opens people soon for what is produced
Pressure test is not done in hole, and many company's buyings return just to leak everywhere less than 0.25MPa when quick opening manhole's pressure test；Client
Medium just will appear gasket damage later several times for handling, need replacing.
Invention content
The purpose of this utility model is to provide for a kind of quick opening manhole bearing container.Solve harmful influence tank car, JB/
It needs to bear internal pressure or instantaneous pressure in tank container as defined in T4782-2007 under the operating mode of use≤0.6Mpa not
Dielectric leakage can occur or need additional increase operating pressure to lay down medium；Make than the common quick opening manhole with silicagel pad
With long lifespan, common quick opening manhole's Reusability with silicagel pad just will appear gasket damage, specially gasket 10 times substantially
" misrun " " stinging meat " phenomenon, influences usability and leakproofness, and can be with the quick opening manhole coated with nonstandard polytetrafluoroethylene (PTFE)
Solves the above problem.This programme is in quick opening manhole using polytetrafluoroethylene (PTFE) cladding pad, the intensity for increasing by 8 pawl ear mounts, use
GB150《Pressure vessel》The required intensity of manhole cover is calculated in detail.And the quick opening manhole in market is using silica gel
Either rubber pad manhole cover does not make with the thickness of cylinder or is more than cylinder thickness 2mm, silicon to pad by calculating only to rely on
- 40 DEG C of rubber cushion temperature in use ~ 230 DEG C are not suitable for prominent face flange, male and fomale(M＆F), tongue and groove flange structure, by test of many times table
Bright silicagel pad is easily used to damage in tongue and groove flange；Polytetrafluoroethylene (PTFE) cladding pad -180 DEG C of temperature in use ~ 250 DEG C, are fitted
For the face of dashing forward, male and fomale(M＆F) and tongue and groove flange structure.
The utility model is achieved like this：A kind of quick opening manhole bearing container, it is characterized in that lower grip tab and upper
For grip tab in handle, connecting flange has shell ring to be connected outside lid in connecting flange；There is engaging lug outside connection ear mount
Piece, connection ear mount are fixed by wing nut, and connecting in ear mount has eyelet bolt；Connecting shaft is in casing, connection sheet A, connection sheet
B, the both ends connection sheet C are compressed by nut.
By adopting the above-described technical solution, meeting can use in the operating mode in 0.6MPa, increase quick opening manhole's
Intensity and leakproofness；Since using trapezoidal polytetrafluoroethylene (PTFE) cladding pad, service life extends；Structure is highly practical, simple in structure.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1, lower grip tab；2, upper grip tab；3, handle；4, connecting flange；5, lid；6, shell ring；7, engaging lug
Seat；8, attachment lug；9, wing nut；10, eyelet bolt；11, nut；12, connecting shaft；13, casing；14, connection sheet A；15、
Connection sheet B；16, connection sheet C.
Specific implementation mode
The utility model is described in further detail with example below in conjunction with the accompanying drawings.
In Fig. 1, lower grip tab 1 and upper grip tab 2 are in handle 3, and connecting flange 4 is outside lid 5, connecting flange 4
Inside there is shell ring 6 to be connected；There are attachment lug 8, connection ear mount 7 to be fixed by wing nut 9 outside connection ear mount 7, connecting has in ear mount 7
Eyelet bolt 10；In casing 13, connection sheet A14, connection sheet B15, the both ends connection sheet C16 are compressed connecting shaft 12 by nut 11.
Before pressure test starts, trapezoidal polytetrafluoroethylene (PTFE) is coated in the groove for padding embedded piece number connecting flange 4, it is trapezoidal poly-
Outside, small size is in groove for the large scale of tetrafluoroethene cladding pad, after pressure test starts, under being acted on due to internal pressure, and people
The bending stress of port lid gradually increases.Expansion, quick opening manhole tightly seal a bit in the shear action of pawl bolt outward, and gasket uses
Be trapezium structure, therefore polytetrafluoroethylene (PTFE) cladding pad is fastened by bolt, and cladding pad has a good compression ratio, rebound degree,
Stress relaxation rate and sealing leak rate so that in fastener cycle, gasket is not in damage.Pressure test is mainly identifier
Intensity, the leakproofness of port lid, whether fillet weld is defective to cause to leak.Pressure test requires to leak, and manhole cover exists
It does not deform in pressure-resistant experimentation and abnormal voice.
