Abstract
The utility model discloses a compound diaphragm sheet used for a diaphragm pump and a diaphragm valve, which is mainly characterized in that a fluoroplastic layer is arranged on a working surface for medium contacting of a film body, a plurality of concentric-ring-shaped strengthening ribs are arranged on the film body and the fluoroplastic layer. The utility model has the advantages of corrosion prevention, aging resistance, strong fatigue resistance, good self-cleaning capability, and convenient changing and washing.
Description
The utility model relates to a kind of diaphragm that is used for diaphragm pump and membrane valve.
Diaphragm pump is a kind of as the positive displacement reciprocating pump, relies on the diaphragm motion, makes the seal operation spatial volume produce cyclically-varying, to transmit energy, so the quality of diaphragm directly influences the working efficiency and the working life of diaphragm pump.The anti-solvent of existing diaphragm of rubber sheet, ageing-resistant and fatigue performance is relatively poor, and teflon diaphragm flexible resistance is poor, working life is shorter.
The purpose of this utility model provides a kind of anti-solvent, ageing-resistant and fatigue resistance good, the composite diaphragm sheet of long service life.
The utility model is made up of film body (1) and bolt (2), and the working surface of film body (1) is provided with fluorine and moulds layer (3).Film body (1) and fluorine are moulded on the layer (3) can set up stiffening rib.The quantity of stiffening rib is to be five on the film body (1), and it is six that fluorine is moulded on the layer (3).
Because inwall of the present utility model, i.e. medium contact working surface has additional fluoroplastics layer, and film body and fluorine are moulded layer and be provided with stiffening rib, thus anti-solvent, ageing-resistant and fatigue resistance is high, and easy cleaning, self-cleaning is good, long service life.
Accompanying drawing 1 is the utility model structural representation.
Further describe the utility model below in conjunction with drawings and Examples.
Film body (1) can be made of high elasticity and ozone proof special synthetic rubber, moulds the stable of layer (3) morpheme to guarantee fluorine.Bolt (2) is positioned at the boss center hole of film body (1), in order to connect transmission part, guarantees the diaphragm proper functioning.Fluorine is moulded layer (3) and is provided with six annular concentric stiffening ribs, and film body (1) is provided with five annular concentric stiffening ribs, with the working life and the service behaviour of abundant raising diaphragm.
The utility model mainly can be applicable to membrane pump and barrier film valve, compares the fluid resistance with existing barrier film sheet Power is littler, except simple substance fluoride and molten alkali metal, and the most chemical industry media of ability, stability is high. Can super-long-term under the normal pressure work condition continuous operation not indeformable, not damaged, and change and clean very square Just.
Claims (3)
1, a kind of composite diaphragm sheet of forming by film body (1) and bolt (2), it is characterized by film body (1) inwall be provided with fluorine mould the layer (3).
2,, it is characterized by film body (1) and fluorine and mould layer (3) and be provided with stiffening rib by the described composite diaphragm sheet of claim 1.
3, by claim 1,2 described composite diaphragm sheets, it is characterized by film body (1) and be provided with five stiffening ribs, fluorine is moulded layer (3) and is provided with six stiffening ribs.
