FIELD: heat engineering.
SUBSTANCE: invention relates to heat engineering and can be used in plate heat exchangers. In a plate heat exchanger, consisting of bearing steel plates with lodgements, and thinner plates of corrugated shape located between them, the thickness of which is 15–20 times less than the thickness of the bearing plates, and seals connected to each other by pins fixed in the holes of the bearing plates, each of the pins is equipped on one side with a head in the form of a nut fixed on the pin by means of a pin, on the other side - by a nut inserted into a locking bushing with a retainer, wherein each bearing plate has recesses communicating with the holes for the pin, with the possibility of fixing a retainer in them, made on the locking bushing and having a shape mating the recess on the bearing plate.
EFFECT: simplification of plate heat exchanger installation and usage of maximally unified parts.
