Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments.

[0018] A plate heat exchanger gasket for easy installation, such as figure 1 As shown, it includes a body 1 and a positioning part 2. The outer edge of the body is integrally formed with a plurality of positioning parts at intervals. The positioning part is a T-shaped structure. The two ends of the positioning part are integrally extended to the body and formed with protrusions. 2A, the gasket can be quickly installed and positioned on the plate (not shown in the figure) through the protrusion, and the left and right ends of the body are formed with corner holes 4 .

[0019] In this embodiment, eight positioning parts are installed at intervals. During the production process of the heat exchanger, the gasket is placed on the front of the plate, and then the protrusion of the positioning part is installed on the back of the pla...

Abstract

The invention relates to a sealing gasket convenient to install, of a plate heat exchanger. The sealing gasket comprises a body and location parts, wherein a plurality of location parts are integrally produced on the outer edge of the body at intervals; each location part is of a T-shaped structure; and lugs are integrally produced on two end parts of each location part in a manner of extending towards the body. The section structure of the body is that the front surface of the body is composed of two inclined surfaces, and the back surface of the body is composed of a plane and two symmetrical inclined surfaces. The sealing gasket is installed in a sealing groove between two plates, and can be conveniently and rapidly installed on the plates through the location parts, without movement, thus the sealing performance is effectively improved. According to the sealing gasket, a fluid can be only drained from the positions of rectangular grooves through the arrangement of the rectangular grooves, and mixing of two mediums is avoided, thus operation is safer.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, in particular to a sealing gasket for plate heat exchangers which is easy to install. Background technique [0002] The plate heat exchanger is made of many punched corrugated thin plates at a certain interval, sealed by gaskets around them, and overlapped and compressed by frames, etc. The four corner holes between the plates and the gaskets form fluid distribution pipes and collecting tubes. [0003] During use, the temperature inside the heat exchanger will continue to change, which will reduce the overall sealing ability of the gasket, resulting in fluid leakage and internal leakage, and poor corrosion resistance, thus reducing the quality of the heat exchanger. [0004] After searching, the following two published patent documents were found, and the specific disclosure content is as follows: [0005] 1. Patent document: A gasket for a plate heat exchanger (notification number CN20...
