The utility model aims at providing a plate heat exchanger slab seal structure, the slab is closely connected with the rubber packing pad, and multiple seal is sealed effectual.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a plate heat exchanger slab seal structure, includes the sealed seal groove on sealed pad and the slab, sealed angular hole and the periphery of filling up set up to twice sealing strip, and local connection between the twice sealing strip, the seal groove on the slab sets up to the recess with the corresponding position of sealing strip and sealing strip junction, the corresponding position in fretwork position sets up to the arch between seal groove on the slab and the twice sealing strip, the sealing strip outside is equipped with T type couple, be equipped with the couple groove with the corresponding position of T type couple on the slab.
The hollow-out is in a long strip shape, and the hollow-out is uniformly arranged between two sealing strips in a subsection mode.
The sealing gasket is provided with four corner holes, and two corner holes on the upper side and the lower side of one side are provided with corner hole secondary sealing strips.
The plate comprises angle holes, a plate flow guide area and a plate heat exchange area, wherein the plate heat exchange area is arranged in the middle of the plate, and the plate flow guide area is arranged at two ends of the plate heat exchange area.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a slab seal structure adopts the sealed form of twice, and sealed effect is better, has solved the heat exchanger installation and has accomplished the back, because installation error, perhaps live time overlength, the heat exchanger outside that causes leaks and interior hourglass-cold and hot runner phenomenon of crossing water mutually, has saved plate heat exchanger whole manufacturing equipment cost of labor, has increased plate heat exchanger whole life simultaneously. Additionally, the utility model discloses a double-pass is sealed to adopt integrated configuration, and the outside is passed through T type couple and is connected with the slab, and the slab is connected more closely with rubber seal pad, can effectively avoid the installation error, strengthens sealed effect, and the installation of being convenient for moreover is dismantled.
