Description

A kind of EPDM seal gasket of high abrasion

Technical field

The utility model belongs to rubber product field, is related to a kind of rubber mat, and especially a kind of EPDM of high abrasion is close Potting pad.

Background technique

Ethylene propylene diene rubber is the terpolymer of ethylene, propylene and non-conjugated diene hydrocarbon, and product price is lower, chemistry Stability is good, and wearability, elasticity and oil resistance are preferable, is often used as seal gasket use, is plate-type heat-exchange by it The seal gasket of device.

Plate heat exchanger is in use, and seal gasket is component that is most important, needing most rigors.Because board-like change Not only narrow space carries out between plate for hot device exchange, but also the seal gasket between plate also assists in heat exchange, sealing Rubber mat will not only seal up medium, and making it, external environment does not leak, but also prevent mutual mixed between exchange media.

Existing seal gasket mostly uses three kinds of forms of bonding, hidden discount and hanging buckle with the connection between plate heat exchanger.Hanging buckle Mode due to easy to operate, it is more welcome.The seal gasket of hanging buckle form is the inside and outside spacers in rubber mat ontology Uniformly distributed hanging buckle when connection, realizes quickly positioning on the plate body by the way that hanging buckle to be hung over to plate heat exchanger.Usual hanging buckle is and rubber mat Ontology is integrally formed EPDM material, in the case of long-term use, is easy to deform because of wear and aging at hanging buckle It is even broken, to not have the effect of position limiting sealed rubber mat, and then cannot be guaranteed the sealing performance of plate heat exchanger.

By the retrieval to patent document, patent document identical with present patent application is not found.

Summary of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of structure is simple, high abrasion ability is strong, Facilitate installation, good seal performance, the EPDM seal gasket being easily achieved.

The utility model solves its technical problem and adopts the following technical solutions to achieve:

A kind of EPDM seal gasket of high abrasion, including rubber mat ontology, it is characterised in that: the rubber mat ontology is cut Face is rectangle, and the outer surface of rubber mat plate body is provided with one layer of polytetrafluoroethylene film, polytetrafluoroethylene film and rubber mat ontology Collectively form hermetic unit, further include coupling part, the coupling part by one hook constitute, the hook by limit section, install section And section composition is mounted, it is coated with the section that installs of hook in the middle part of hermetic unit, the limit section of hook and mounts section difference position The both ends of hermetic unit.

Moreover, the hook is the metal material that corrosion-inhibiting coating is arranged in polytetrafluoroethylene (PTFE) material or surface.

Moreover, the polytetrafluoroethylene film with a thickness of 0.05-0.1mm.

The advantages and positive effects of the utility model are as follows:

1. the EPDM seal gasket of high abrasion, by squeezing out one layer outside the rubber mat of existing EPDM material Tetrafluoroethene housing reaches the superior performance of seal gasket using the property of tetrafluoroethene, meanwhile, it is installed in hermetic unit poly- The hook of tetrafluoroethene material or metal material, since its surface is smooth therefore installs conveniently, since its wear-resisting property is higher than three First the third material of second therefore, can be to avoid hook in the case where being chronically exposed to outer after being mounted on the plate body of heat exchanger It is rubbed, thus the problem of influencing leakproofness.

2. the EPDM seal gasket of high abrasion is by the way that polytetrafluoroethylene film is designed as 0.05-0.1mm Seal gasket can also maintain the ability of flexible deformation with certain degree of hardness, facilitate this seal gasket in heat exchanger plate Limit on body is avoided the problem that because of the existing pure excessively soft and inconvenient installation of EPDM seal gasket.

3. design is scientific and reasonable for the utility model, have that high abrasion ability is strong, facilitates installation, good seal performance, is easy to real Existing advantage is a kind of EPDM seal gasket with higher innovation.

Specific embodiment

The embodiments of the present invention are further described below in conjunction with attached drawing:

A kind of EPDM seal gasket of high abrasion, including rubber mat ontology 4, innovation is: the rubber mat sheet The section of body is rectangle, and the outer surface of rubber mat plate body is provided with one layer of polytetrafluoroethylene film 2, polytetrafluoroethylene film and glue Pad body collectively forms hermetic unit, further includes coupling part, the coupling part by one hook constitute, the hook by limit section 1, It installs section 3 and mounts the composition of section 5, be coated with the section that installs of hook in the middle part of hermetic unit, the limit section of hook and mount section The both ends of position seals part respectively.

The hook is the metal material that corrosion-inhibiting coating is arranged in polytetrafluoroethylene (PTFE) material or surface.

The polytetrafluoroethylene film with a thickness of 0.05-0.1mm.

The utility model utilizes four by squeezing out one layer of tetrafluoroethene housing outside the rubber mat of existing EPDM material The property of vinyl fluoride reaches the superior performance of seal gasket, meanwhile, polytetrafluoroethylene (PTFE) material or metal material are installed in hermetic unit The hook of matter, since its surface is smooth therefore installs conveniently, since its wear-resisting property is higher than EPDM material, hang After on the plate body of heat exchanger, in the case where being chronically exposed to outer, it can be rubbed to avoid hook, to influence leakproofness The problem of.

Although disclosing the embodiments of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be with Understand: departing from the utility model and spirit and scope of the appended claims, various substitutions, changes and modifications are all can Can, therefore, the scope of the utility model is not limited to the embodiment and attached drawing disclosure of that.
