Abstract
A cladding type non-joint sealing ring comprises a ring body and a cladding layer, and the cladding layer is covered on the inner circle of the ring body in a non seam mode. The cladding type non-joint sealing ring is strong in bearing capacity, good in elasticity, chemical corrosion resistant, good in sealing effect, and suitable for being used in rigorous strong corrosive medium heat exchange working condition. The cladding type non-joint sealing ring is various in geometrical shape of cross section and without joint, and capable of effectively preventing and isolating etching and swelling of acid-base and organic solvent on rubber materials, expressing high original elasticity of rubber base materials and enabling sealing effect for a heat exchanger to be good. Meanwhile, the cladding type non-joint sealing ring is capable of enhancing core bearing capacity of the ring body, enhancing sealing effect accordingly, further improving use value for the sealing ring, prolonging service life of a heat exchanger unit, and having a large pushing function for an enterprise to save energy and reduce consumption.
Description
Technical field
The utility model relates to a kind of technical field of heat exchanger, specifically a kind of clad type non junction sealing ring.
Background technology
Heat exchanger is a kind of high-efficient energy-saving environment friendly equipment that is widely used in the national economy all trades and professions, and this series products has the advantages such as heat exchange efficiency height, floor space are little, convenient disassembly.As the rubber seal parts of such equipment key part such as rubber sheet gasketing, rubber seal, bearing capacity is no more than 2.5MPa, operating temperature usually must be below 200 ℃, and can not be applicable to the special operation condition media such as strong acid, highly basic and organic solvent fully.In the prior art, heat exchanger seal member material, be generally ethylene propylene diene rubber, fluorubber, acrylonitrile-butadiene rubber, materials can satisfy instructions for use substantially under the medium of routine and temperature, but its rate of corrosion is accelerated under the special operation condition media such as strong acid, highly basic, organic solvent, causes the early stage seal failure of heat exchanger, and seal failure also occurs easily under high temperature, condition of high voltage, cause unit to move, and then limited the range of application of heat exchanger.
Summary of the invention
The purpose of this utility model is to provide a kind of clad type non junction sealing ring, and its bearing capacity is strong, excellent spring, resistance to chemical attack, and sealing effectiveness is better; Be applicable in the strong corrosive medium heat-exchanging state of harshness, use.
The utility model is achieved through the following technical solutions:
A kind of clad type non junction sealing ring is comprised of circle body and clad, and clad 2 covers the inner ring of circle body 1 without seam.
Above-mentioned circle body adopts ethylene propylene diene rubber, or acrylonitrile-butadiene rubber, or the fluorubber material.
Above-mentioned clad adopts polytetrafluoroethylene (PTFE) thermoplasticity macromolecule resin material.
Above-mentioned circle body sealing non junction can be circle, or oval, or rectangle, or rhombus.
Advantage of the present utility model and beneficial effect:
1, circle body of the present utility model adopts the special synthetic rubber material, the new type rubber material auxiliary agents such as peroxidating diethyl propyl benzene, assistant crosslinking agent VP-4 have been used simultaneously, vulcanize compressing, strengthened the rubber sealing ring physical and mechanical properties, its hot strength is reached more than the 20MPa, bearing capacity is brought up to 3.6 MPa from 2.5 MPa, has improved the bearing capacity of heat exchanger, has widened it and has used territory.
2, clad of the present utility model is polytetrafluoroethylene (PTFE) thermoplasticity macromolecule resin material; Carry out surface activation process by special rubber chemicals, rubber substrate and clad material organic composite are arrived together, sulfuration is pressed into the sealing ring of composite, and sealing non junction, stop and isolated strong acid-base and organic solvent to etch and the swelling of elastomeric material, brought into play the original high resiliency of elastomeric material, so that the sealing of heat exchanger is more effective.
3, the utility model is applied to heat exchanger, efficiently solve the rubber seal parts to the anti-patience of strong acid, highly basic, organic solvent, and improved its bearing capacity, further enlarge the range of application of heat exchanger, and then extension device service life, reduce the operating cost of equipment.
4, the utility model has solved the problem of the joint of the thermoplasticity macromolecule resin materials such as polytetrafluoroethylene (PTFE), make sealing ring not only surmount in appearance original joint and expose faulty state, and the inside and outside layer structure of one integrated mass, strengthened the core bearing capacity of circle body, thereby strengthened sealing effectiveness and then improved the use value of sealing ring, prolonged the service life of heat-exchanger, for the industry energy conservation consumption reduction plays huge impetus.
5, making of the present utility model needs through the specially-shaped sulfuration process, makes rear non junction, smooth surface is smooth, and sealing effectiveness is good, and cross sectional shape can design according to the heat exchanger seal request, to satisfy different instructions for uses.
6, the utility model is heat exchanger clad type non junction sealing ring, and its bearing capacity is strong, excellent spring, resistance to chemical attack, and sealing effectiveness is better; Be applicable in the strong corrosive medium heat-exchanging state of harshness, use.
