The sealing gasket in the plate heat exchanger is a part of the sealing heat exchanger embedded in the plate heat exchanger plate, seals the fluid channel and guides cold and hot fluid to alternately flow into the respective channels.
The plate heat exchanger adopts a sealing gasket as a rubber material, the general working pressure is less than 2.5MPa, and the working temperature is less than 170 ℃. There are three ways of fixing the sealing gasket of the plate heat exchanger on the plate, one is to directly adhere the sealing gasket in the sealing groove of the plate by using an adhesive, the sealing gasket is called as an adhesive pad, the second is to set a hook structure around the sealing gasket, the sealing gasket is fixed in the sealing groove of the plate by matching the hook with the periphery of the plate, the sealing gasket is called as a hanging pad, the third is to set a snap fastener structure on the sealing gasket or around the sealing gasket, the sealing gasket is fixed in the sealing groove of the plate by pressing, and the sealing gasket is called as a buckling pad. The snap fastener type sealing gasket is used, so that the plate heat exchanger can be overhauled and maintained more rapidly, the gasket is replaced conveniently and rapidly, the service life of the gasket is prolonged, and the maintenance cost is reduced.
The current snap fastener gasket structure is through setting up a plurality of cylindrical or rectangle snap fasteners above that, cylindrical structure is through being connected with the snap fastener hole in the slab seal groove, because the connecting hole is in the seal groove bottom, causes the seal to be not tight easily, and influence slab seal groove intensity, rectangular structure is through linking to each other with slab edge and fixing in the seal groove, snap fastener connected position is single thin, connect unstably, the gasket is liable to scurry the position, deviate from the seal groove, the sealing function decline that above-mentioned two kinds of connected mode all can make the gasket leads to leaking even actual effect, influence plate heat exchanger's performance.
The patent document with application number 201621001556.3 discloses a rectangular snap fastener sealing gasket for a plate heat exchanger, as shown in fig. 1 and 2, a plurality of snap fasteners are arranged on the outer side of the upper edge of a gasket main body 1, each snap fastener is composed of two symmetrically arranged connecting ribs 3 and a rectangular snap fastener main body 4 connected between the two connecting ribs 3, the connecting ribs 3 are vertically connected with the gasket main body 1, when the rectangular snap fastener sealing gasket is used, the gasket main body 1 is arranged at a corresponding position of a heat exchange plate, a clamping hole 5 which is matched with the rectangular snap fastener main body 4 in shape is processed on the heat exchange plate, and each rectangular snap fastener main body 4 is fixed in the clamping hole 5 in a pressing mode. The rectangular snap fastener sealing gasket is characterized in that the snap fastener main body 4 is fixedly clamped by processing the clamping holes 5 around the plate, and the clamping holes are processed around the plate, so that the rigidity and strength of the plate are reduced, the service life of the plate is prolonged, and meanwhile, the deformation of the plate is easy to cause, so that the service performance of the plate heat exchanger is affected.
Disclosure of Invention
The utility model aims to provide a snap fastener gasket and plate fastener fixing structure of a plate heat exchanger, which has reasonable structure and accurate positioning, namely realizes quick overhaul and maintenance of snap fastener sealing gaskets, convenient and quick gasket replacement, prolongs the service life of the gaskets and reduces maintenance cost, ensures the sealing effect of the gaskets, simultaneously avoids punching positioning holes on the plate, ensures the rigidity and strength of the plate, prolongs the service life of the plate, avoids deformation of the plate caused by punching, and ensures the service performance of the plate heat exchanger.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the snap fastener gasket and plate buckle fixing structure of a plate heat exchanger, the shape of a main body sealing strip of the snap fastener gasket is matched with that of a sealing groove of the plate, a plurality of snap fasteners are arranged on the outer side of the main body sealing strip of the snap fastener gasket, the whole snap fastener is T-shaped, and one side of the transverse edge of the T-shaped is connected with the main body sealing strip into a whole; the outer edge of the plate and the snap fastener gasket are provided with snap fastener positions corresponding to the positions of the snap fasteners, are concave parts of the plate corrugations, two transverse bulges are arranged between the two corrugated bulges, a groove gap is reserved between the two transverse bulges, and the groove gap is exactly matched with a T-shaped snap fastener with a groove formed by the concave parts of the plate corrugations.
The snap fasteners are uniformly arranged on the periphery of the snap fastener gaskets.
Compared with the prior art, the utility model has the beneficial effects that:
the snap fastener gasket and plate buckle fixing structure of the plate heat exchanger is reasonable in structure and accurate in positioning, namely the snap fastener sealing gasket is rapidly overhauled and maintained, the gasket is conveniently and rapidly replaced, the service life of the gasket is prolonged, the maintenance cost is reduced, the sealing effect of the gasket is guaranteed, positioning holes are avoided being drilled in the plate, the rigidity and strength of the plate are guaranteed, the service life of the plate is prolonged, deformation of the plate caused by punching is avoided, and the service performance of the plate heat exchanger is guaranteed.
