Embodiment Construction

[0015] A sealing gasket for a plate heat exchanger of the present invention uses relatively high content of aramid fibers and artificial rock wool (sepiolite) as reinforcing materials (i.e. fillers), and uses natural rubber, styrene-butadiene or NBR is used as the adhesive, organic and inorganic fibers are used as the frame, and the sheet is specially made by rolling method, that is, NY4250 oil-resistant and asbestos-free rubber sheet. The sheet is 100% asbestos-free and has excellent comprehensive performance. The prepared NY4250 oil-resistant asbestos-free rubber sheet with a thickness of 3.6 mm is laser cut into a shape corresponding to the sealing groove of the sheet, which is the sealing gasket of the present invention. Its main technical characteristics are shown in Table 1 below:

Abstract

The invention discloses a sealing gasket for a plate heat exchanger. The sealing gasket is prepared from an oil-proof non-asbestos rubber material. The oil-proof non-asbestos rubber is NY4250, the thickness is 3.5-4.0 mm, the highest temperature born by the rubber is 250 DEG C, the largest pressure is 1.6 MPa, and the compression rate is 7-12%. Conventional and traditional concepts are broken through, technical bias in the industry is overcome, the oil-proof non-asbestos rubber gasket is organically combined with the plate heat exchanger, pioneer application of the oil-proof non-asbestos rubber to the plate heat exchanger is created, an unexpected technical effect is achieved, and the sealing gasket has substantive features. The sealing gasket has remarkable advantages of being excellent in temperature resistance, high in pressure bearing capacity, non-poisonous, safe and environmentally friendly, simple in preparation process, convenient to disassemble, assemble and clean, wide in application range and the like.

Description

technical field [0001] The invention relates to the field of processing and manufacturing of plate heat exchangers, in particular to a sealing gasket used for sealing between plates of the plate heat exchanger. Background technique [0002] Plate heat exchanger is a high-efficiency, energy-saving and compact heat exchange equipment, which has the advantages of high heat transfer efficiency, compact structure, small footprint, wide application range, and convenient installation and cleaning. Its core components are plates and sealing gaskets. The sealing gasket is the key component of the detachable plate heat exchanger. The quality of the gasket has a direct impact on the pressure and temperature resistance, working performance and adaptability. For a long time, the sealing gaskets used in plate heat exchangers are mostly made of nitrile rubber, EPDM rubber or fluororubber, etc. Their general characteristics are good elasticity, large compression ratio and good sealing effec...
