Problems solved by technology

Through the above design, the sealing groove and the sealing gasket can be fitted together more closely, but because the matching relationship is a flat fit, the elastic deformation range is small, and the sealing performance needs to be further improved. The processing of the triangular protrusions in the sealing groove relatively complex

Embodiment 1

[0032] Such as figure 1 , figure 2 As shown, this embodiment provides a plate heat exchanger with good sealing performance, including a number of heat exchange plates 100 that are alternately turned over and stacked on each other and sealing gaskets 200 located between adjacent heat exchange plates 100 , the sealing gasket 200 includes a first sealing portion 210 and a second sealing portion 220 integrally formed on one side of the first sealing portion 210, the first sealing portion 210 includes an embedded arc from bottom to top Shaped bottom 211, slot part 212 and choke top 213, one side of the second sealing part 220 is in contact with one side of the choke top 213 and integrally formed, the second sealing part 220 is opposite to the The other side of the blocking top 213 is provided with a flange 221 downwards, and the heat exchange plate 100 is provided with an embedded arc-shaped groove 110 compatible with the first sealing part 210 and with the flange. The edge 221 ...

Embodiment 2

[0036] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the sealing gasket 200 further includes a third sealing portion 230 located on the side of the first sealing portion 210 and symmetrical to the second sealing portion 220 , The structure of the third sealing portion 230 is symmetrical to that of the second sealing portion 220 . The setting of the third sealing part 230 widens the sealing surface, and the sealing gasket 200 in the symmetrical arrangement state can better resist the uneven force caused by the unstable extrusion force, and reduce the possibility of the sealing gasket 200 detaching from the groove. Yes, in this embodiment, the top of the second sealing part 220 and the first sealing part 210 can be arranged to meet in an arc as shown in the figure, the third sealing part 230 is symmetrical to the second sealing part 220, and the heat exchange plates 100 is provided with a groove matching with the third sealing part 2...

Embodiment 3

[0042] Such as Image 6 As shown, the difference between this embodiment and Embodiment 1 is that the inside of the first sealing portion 210 is hollow, and the groove portion 212 is provided with an air outlet hole 2121 communicating with the hollow structure of the first sealing portion 210 . The interior of the first sealing part 210 is set to be hollow, and the top surface of the blocking top 213 is an arc surface and the arc surface of the embedded arc bottom 211 is conducive to further increasing the elastic deformation range of the first sealing part 210, making it There is a larger deformation space when under pressure, thereby improving the problem of uneven stress on the sealing gasket 200 during compression assembly, and helping to avoid the problem of extravasation of individual parts caused by the inconsistent deformation of the sealing gasket 200 as much as possible.

[0043] The heat exchange plate 100 and the sealing gasket 200 are connected together by a fixed...

Abstract

The invention relates to the technical field of plate type heat exchangers, and discloses a plate type heat exchanger with a good sealing property. The plate type heat exchanger includes a plurality of heat exchanging plate pieces alternately flipped and stacked with each other and sealing gaskets located between every adjacent heat exchanging plate pieces, each sealing gasket comprises a first sealing part and a second sealing part which is located on one side of the first sealing part and integrally formed with the first sealing part, and each first sealing part comprises an embedded arc-shaped bottom, a clamping groove part and a flow stopping top from bottom to top; and one sides of the second sealing parts are in butt joint with one sides of the flow stopping tops and formed integrally, the other sides, opposite to the flow stopping tops, of the second sealing parts are downwardly provided with flanges, and each heat exchanging plate piece is provided with an embedded arc-shaped groove matched with the correspondingly first sealing part and a positioning sealing groove matched with the correspondingly flange. According to the plate type heat exchanger with the good sealing property, installation is simple, the tightness between the heat exchanging plate pieces is good, the sealing gaskets are easier to suffer stress evenly, and sealing is firm.

Description

technical field [0001] The invention relates to the technical field of plate heat exchangers, in particular to a plate heat exchanger with good sealing performance. Background technique [0002] In the pre-treatment of the coating production line, the bath solution in hot water washing, degreasing, phosphating and other processes needs to be heated to the working temperature, and the temperature of the bath solution should be kept as constant as possible during work. Compared with the traditional tube heater heating method, the plate-type replacement The heater is widely used in the pre-treatment heating process of the coating production line because of its higher thermal efficiency, good flexibility, no effective space in the tank, small footprint, and convenient maintenance and cleaning. [0003] At present, in the existing plate heat exchanger, the bottom of the sealing groove of the heat exchange plate adopts a flat form, and the sealing gasket is made of elastic materia...
