Abstract
The utility model relates to a groove gasket for a plate heat exchanger. The groove gasket is made of rubber, and is sealed in a gasket groove between an upper plate and a lower plate of the heat exchanger; grooves are formed in the upper surface and the lower surface of the groove gasket; when the groove gasket is extruded by the upper plate and the lower plate, projections formed by the grooves bear pressure; each projection can form a sealing surface.
Description
Technical field
The utility model belongs to technical field of heat exchangers, and concrete is a kind of groove pad for plate type heat exchanger.
Background technology
When the flat shim using on existing plate type heat exchanger is subject to the extruding of upper and lower plate, upper and lower two planes of pad will be born whole pressure, when pressure is excessive, there is deformation in the pad to the left and right gap of both sides, if pad is subject to excessive pressure for a long time, pad can be out of shape and power is distributed to the left and right sides of pad, the power of the left and right sides also will extend to heat exchanger plate, thereby cause the spacer groove distortion of heat exchanger plate, the sealing property of plate is declined, bearing capacity declines.Can not meet user's normal working pressure.
Utility model content
In view of this, in order to reduce the pressure to the upper and lower plate of plate type heat exchanger, and improve sealing effectiveness.This is novel provides a kind of groove pad for plate type heat exchanger.
For achieving the above object, the utility model adopts following technical scheme:
A kind of groove pad for plate type heat exchanger, material is rubber, be sealed in the spacer groove between upper and lower two heat exchanger plates, it is characterized by: in described groove pad upper and lower surface, have groove, when described groove pad is subject to the extruding of upper and lower plate, the projection being formed by described groove is born pressure, and described each projection can form a sealing surface.
Further, described groove pad upper and lower surface respectively has twice groove, makes upper and lower surface respectively form 3 projections.
Further, the twice groove of described groove pad upper and lower surface departs from the longitudinal centre line of described groove pad cross section separately, makes the projection area of formed centre maximum, and the projection of described centre and the contact area of described upper and lower plate are also maximum.
After adopting above technical scheme, when described groove pad is subject to the extruding of upper and lower plate, six projections that formed by the upper and lower twice groove of groove pad are born pressure.Each projection can form a sealing surface, has also just improved sealing effectiveness.When described upper and lower plate pushes described groove pad and makes it produce distortion, on described groove pad, the deformation that therefore described groove pad produces can be accepted in each projection space around, the pressure that described spacer groove is born reduces, be unlikely to make plate distortion, affect the use of plate, thereby improved the bearing capacity of heat exchanger.Plate type heat exchanger groove pad is more economized than flat shim materials simultaneously, and price is more excellent.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of groove pad for plate type heat exchanger of the utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1:
With reference to figure 1, a kind of groove pad for plate type heat exchanger, material is rubber, be sealed in the spacer groove 2 between upper and lower two heat exchanger plates 1, in described groove pad 3 upper and lower surfaces, have groove 5, the extruding that described groove pad 3 is subject to upper and lower plate 1 produces while being out of shape, and the projection 4 being formed by described groove 5 is born pressure, and described each projection 4 can form a sealing surface.
Embodiment 2:
With reference to figure 1, to compare with embodiment 1, the difference of embodiment 2 is that described groove pad 3 upper and lower surfaces respectively have twice groove 5, make upper and lower surface respectively form 3 projections 4.
Embodiment 3:
With reference to figure 1, compare with embodiment 2, the difference of embodiment 3 is that the twice groove 5 of described groove pad 3 upper and lower surfaces departs from the longitudinal centre line of described groove pad 3 cross sections separately, make the projection area of formed centre maximum, the contact area of the projection of described centre and described upper and lower plate 1 is also maximum.
After adopting above technical scheme, when described groove pad 3 is subject to the extruding of upper and lower plate 1, by described groove pad six projections 4 that Shang Xia 3, twice groove 5 forms, bear pressure.Each projection 4 can form a sealing surface, has also just improved sealing effectiveness.When the described groove pad 3 of described upper and lower plate 1 extruding makes its distortion, on described groove pad 3, the deformation that therefore described groove pad 3 produces can be accepted in each projection 4 space around, the pressure that described spacer groove 2 is born reduces, be unlikely to make plate 1 distortion, affect the use of plate 1, thereby improved the bearing capacity of heat exchanger.Plate type heat exchanger groove pad 3 is more economized than flat shim materials simultaneously, and price is more excellent.
Claims (3)
1. the groove pad for plate type heat exchanger, material is rubber, be sealed in the spacer groove between upper and lower two heat exchanger plates, it is characterized by: in described groove pad upper and lower surface, have groove, when described groove pad is subject to the extruding of upper and lower plate, the projection being formed by described groove is born pressure, and described each projection can form a sealing surface.
2. as claimed in claim 1 for the groove pad of plate type heat exchanger, it is characterized in that: described groove pad upper and lower surface respectively has twice groove, make upper and lower surface respectively form 3 projections.
3. as claimed in claim 1 or 2 for the groove pad of plate type heat exchanger, it is characterized in that: the twice groove of described groove pad upper and lower surface departs from the longitudinal centre line of described groove pad cross section separately, make the projection area of formed centre maximum, the projection of described centre and the contact area of described upper and lower plate are also maximum.
