Abstract
A kind of material reducing supercharging grommet type seal of the part installation small for sealing surface fastening force is provided, including the first sealing strip, the second sealing strip and the 3rd sealing strip, 3rd sealing strip both ends are respectively by bending sealing strip and the first sealing strip and second sealing strip one end vertical connection, the first sealing strip other end is set to end I, the second sealing strip other end is set to end II, the termination of the end II is connected with L-type sealing strip, and the outside of the end I and end II is formed with arc notch.The utility model reduces the area of sealing gasket by making arc notch on sealing gasket, so as to reduce the contact area between sealing surface and sealing gasket, increases the pressure of sealing surface, improves sealing effectiveness.
Description
Technical field
The utility model category equipment air locking manufacturing technology field, and in particular to one kind is used for the small portion of sealing surface fastening force
The material reducing supercharging grommet type seal of part installation.
Background technology
In equipment production installation, installed for the less equipment part of sealing surface fastening force, as flange face or housing are close
Front cover, due to being influenceed by sealing surface fastening force, sealing surface sealing pressure reduces, along with sealing gasket area is big, such as Fig. 4 institutes
Show, the sealing effectiveness for installing parts is bad, and to improve sealing property, it is necessary to be finished to sealing surface, processes
Cost is high.It is therefore desirable to propose to improve.
Utility model content
The technical problem that the utility model solves：A kind of material reducing supercharging for the installation of sealing surface fastening force widget is provided
Grommet type seal, the utility model reduce the area of sealing gasket by making arc notch on sealing gasket, so as to reduce sealing
Contact area between face and sealing gasket, increase the pressure of sealing surface, improve sealing effectiveness.
The technical solution adopted in the utility model：Material reducing boosting type sealing for the installation of sealing surface fastening force widget
Pad, including the first sealing strip, the second sealing strip and the 3rd sealing strip, the 3rd sealing strip both ends are respectively by bending sealing strip
With the first sealing strip and second sealing strip one end vertical connection, the first sealing strip other end is set to end I, and described second is close
The strip of paper used for sealing other end is set to end II, and the termination of the end II is connected with L-type sealing strip, the outside of the end I and end II
It is formed with arc notch.
Wherein, multiple semi-circular projections, the semicircle are uniformly provided with first sealing strip and the second sealing strip
Protuberance is provided with positioning hole, and the junction of the 3rd sealing strip and the first sealing strip and the second sealing strip also is provided with positioning
Hole, positioning hole also is provided with the L-type sealing strip end and knuckle.
The utility model compared with prior art the advantages of：
1st, this programme reduces the area of sealing gasket by making arc notch on sealing gasket, so as to reduce sealing surface with
Contact area between sealing gasket, increase the pressure of sealing surface, improve sealing effectiveness, simple in construction, easy to use, service life
It is long；
2nd, sealing surface pressure, institute are increased due to reducing the contact area between sealing gasket and sealing surface in this programme
Need not be finished again to the sealing surface on flange or housing, so as to reduce processing charges, lower die cost.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model；
Fig. 2 is Fig. 1 I schematic enlarged-scale view；
Fig. 3 is Fig. 1 II schematic enlarged-scale view；
Fig. 4 is the structural front view of existing sealing gasket.
Embodiment
1-3 describes embodiment of the present utility model below in conjunction with the accompanying drawings.
Material reducing for the installation of sealing surface fastening force widget is pressurized grommet type seal, as shown in figure 1, including the first sealing strip
1st, the second sealing strip 2 and the 3rd sealing strip 3, the both ends of the 3rd sealing strip 3 are respectively by bending the sealing strip of sealing strip 4 and first
1 and one end vertical connection of the second sealing strip 2, the other end of the first sealing strip 1 be set to end I 7, second sealing strip 2 is another
One end is set to end II 6, and the termination of the end II 6 is connected with L-type sealing strip 5, the sealing strip of the first sealing strip 1 and second
Multiple semi-circular projections 9 are uniformly provided with 2, the semi-circular projection 9 is provided with positioning hole 10, the 3rd sealing strip 3
Positioning hole 10 also is provided with the junction of the first sealing strip 1 and the second sealing strip 2, at the end of L-type sealing strip 5 and knuckle
Provided with positioning hole 10, as shown in Figures 2 and 3, the outside of the end I 7 and end II 6 is formed with arc notch 8.The utility model
The area of sealing gasket can be reduced by making arc notch 8. on sealing gasket, so as to reduce between sealing gasket and sealing surface
Contact area, increase the pressure of sealing surface, improve sealing effectiveness, sealing surface fastening force is small, simple in construction, easy to use, uses
Long lifespan；Meanwhile the utility model increases sealing face pressure due to reducing the contact area between sealing gasket and sealing surface
By force, so need not be finished again to the sealing surface on flange or housing, so as to reduce processing charges, reduce mould and take
With raising stock utilization.
Above-described embodiment, simply preferred embodiment of the present utility model, not it is used for limiting the utility model practical range,
Therefore all equivalence changes done with content described in the utility model claims, the utility model claims model all should be included in
Within enclosing.
