Description
Technical Field
The utility model relates to a plate heat exchanger especially relates to a high pressure resistant plate heat exchanger.
Background
The plate heat exchanger is a new type high-efficiency heat exchanger formed by stacking a series of metal sheets with certain corrugated shapes. The heat exchanger mainly comprises plates, a sealing gasket and a supporting frame, wherein a channel is formed between every two adjacent plates, and heat exchange is carried out through the plates. The frame is composed of a fixed pressure plate, a movable pressure plate, an upper guide rod, a lower guide rod, a clamping bolt and the like. The plate heat exchanger plate is formed by installing plate sheets between a fixed pressing plate and a movable pressing plate in a superposed mode and then clamping the plate sheets by using clamping bolts.
Because the plate of the plate heat exchanger always punches 4 corner holes at four corners, the strength of the position of the edge of the plate close to the corner holes is very low, and the plate is a place which is often leaked in a high-pressure working condition.
The cross section of the plate heat exchanger sealing gasket is generally in a triangular roof structure shape, the sealing effect is good under the operating pressure of 2.5MPa, but the sealing gasket is always extruded out of a sealing groove by high pressure when the operating pressure exceeds 2.5MPa, so that fluid leakage is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a high pressure resistant plate heat exchanger has solved the low problem of plate heat exchanger pressure-bearing among the prior art, improves plate heat exchanger pressure-bearing effect 60%.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a high-pressure-resistant plate heat exchanger comprises a fixed clamping plate, a plate bundle and a movable clamping plate, wherein the plate bundle consists of a plurality of plates, and the plates are tightly sealed with plate sealing grooves through sealing rubber gaskets; the cross-section of the sealing rubber gasket is serrated, and the two sides of the edge of the plate corner hole are provided with pressing table folding edges.
The center line of the pressing table folding edge penetrates through the center of the corner hole, the bending height of the pressing table folding edge is 5mm, and the length of the pressing table folding edge is 100-150 mm.
The number of teeth of the sawteeth of the sealing rubber gasket is 3.
The number of the corner holes of the plate is 4.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model relates to a high pressure resistant plate heat exchanger, plate corner hole department intensity increase more than 2 times, and the sealed effect of seal gasket is showing more, improves complete machine pressure-bearing effect 60%. The utility model discloses can be applicable to the higher operating mode of some operating pressure.
