Abstract
The utility model relates to an improved structure of an adhesive-free sealing gasket body for a plate heat exchanger. The improved structure comprises a bar-shaped sealing gasket body, wherein the outer side of the bar-shaped sealing gasket body is provided with a hook which is integrated with the sealing gasket body; and the hook is positioned at the middle-upper part of the centerline on the lateral surface of the sealing gasket body. The improved structure is characterized in that the upper surface and the lower surface of the sealing gasket body are provided with grooves. Because the form that middles of the double planes are provided with the grooves is adopted and face sealing is adopted as the sealing manner, the improved structure has stronger sealability and stronger friction force; a gasket and a plate are combined more firmly, and the grooves also reserve a space for the sealing gasket, the situation that internal stress is too high can be eased, so that physical properties, such as breaking strength, tearing strength and hardness of the sealing gasket are enhanced, and the situation that the sealing gasket is extruded out of a gasket groove to generate cracks or being crushed and the like can be prevented from happening.
Description
Technical field
The utility model belongs to heat exchanger manufacturing technology field, particularly relates to a kind of plate type heat exchanger and improves with exempting from sticking formula sealing gasket main body structure.
Background technology
Reasonably sealing gasket is to guarantee that plate type heat exchanger can carry the assurance of not revealing than big pressure, and traditional plate type heat exchanger generally adopts the strip gasket seal, and its gasket seal is inlaid in the heat exchanger plate body, is prone to come off at the assembling process Intermediate gasket; Influence product efficiency, in order to address this problem, operating personnel are when the fitting tight pad, at its surface-coated adhesive; Also need use the clear adhesive of cleaning agent after the assembling, otherwise adhesive can cause corrosion to pad, thereby cause the swelling of pad; Forfeiture elasticity, and then cause the easy corrosion cracking of spacer groove, and contaminated-fluid; And there is certain harm in health, occurs a kind of sticking formula sealing gasket of exempting from present, the sealing pad can hanging support on plate body; Solved caducous defective, the upper surface of existing sealing gasket body is the single line sealing, poor sealing performance.Original common form of the bottom surface of sealing gasket body is the plane, because gasket seal compression does not have deformation space, and causes internal stress too high easily; Be prone to take place fatigue failure; Gasket seal also can occur when serious and extrude spacer groove, cause leaking, shorten heat exchanger service life.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, be easy to make, the plate type heat exchanger of easy to assembly, good seal performance, long service life is with exempting from sticking formula sealing gasket main body structure improvement.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of plate type heat exchanger improves with exempting from sticking formula sealing gasket main body structure; Comprise bar shaped sealing gasket body; The outside of said bar shaped sealing gasket body is provided with the hook with sealing gasket body one; Said hook is positioned at the middle and upper part of diaphragm seal body side surface center line, it is characterized in that: the upper and lower surfaces of said sealing gasket body is equipped with groove.
The utility model can also adopt following technical measures:
The cross section of said sealing gasket body is rectangular, and four drift angles of rectangular pad lamellar body are equipped with chamfering.
Said sealing gasket body is processed Long Circle.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly the upper and lower surfaces at the sealing gasket body is provided with groove, adopts the middle form that has groove of this biplane; Seal form is the face sealing; Sealing is stronger, and frictional force is stronger, and pad combines more firm with plate; And groove also leaves deformation space to gasket seal; It is too high to alleviate internal stress, makes its physical property (like breaking strength, tearing strength and hardness etc.) be able to strengthen, and avoids being extruded spacer groove, cracks or situation such as crushed takes place.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is a sealing gasket body cross section structure sketch map;
Fig. 3 is the another kind of cross section structure sketch map of sealing gasket body;
Fig. 4 is a prior art sealing gasket body construction sketch map.
Among the figure: 1, sealing gasket body; 1-1, groove; 2, hook.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 to Fig. 4; A kind of plate type heat exchanger improves with exempting from sticking formula sealing gasket main body structure; Comprise bar shaped sealing gasket body 1, the outside of said bar shaped sealing gasket body 1 is provided with the hook 2 with sealing gasket body one, and said hook 2 is positioned at the middle and upper part of diaphragm seal body side surface center line.In order to increase the contact area with plate, the upper and lower surfaces of said sealing gasket body 1 is equipped with groove 1-1,
In the said structure, the cross section of said sealing gasket body is rectangular, and four drift angles of rectangular pad lamellar body are equipped with chamfering.Also can said sealing gasket body be processed Long Circle.
Adopt the middle form that has groove of this biplane, seal form is the face sealing, and sealing is stronger; Frictional force is stronger; Pad combines more firm with plate, and groove also leaves deformation space to gasket seal, and it is too high to alleviate internal stress; Make its physical property (like breaking strength, tearing strength and hardness etc.) be able to strengthen, avoid being extruded spacer groove, crack or situation such as crushed takes place.
