Abstract
The utility model relates to an air-vent valve diaphragm, including the rubber substrate, compound one deck resistance to deformation, withstand voltage, corrosion-resistant complex film below the rubber substrate, the complex film can adopt the aluminium foil, wash materials such as lun. The rubber composite diaphragm not only has the characteristics of corrosion resistance and elasticity of the rubber diaphragm, but also improves the deformation resistance and pressure resistance of the diaphragm. The bearing strength, the swelling resistance and the corrosion resistance of the pressure regulating membrane are greatly superior to those of the currently used single-layer rubber pressure regulating membrane.
Description
Technical field
The utility model relates to a kind of pressure regulator valve diaphragm, is applicable on the pressure regulator valve of industry and conveying, adjusting and the control of Vehicular liquefied petroleum gas and natural gas.
Background technique
At present, voltage regulation diaphragm on the pressure regulator valve of use in liquefied petroleum gas (LPG) and natural gas system all adopts the individual layer elastomer diaphragm, the effect about composition produces diaphragm swelling and corrosion in liquefied petroleum gas (LPG) and the natural gas because rubber material is subjected to, cause the voltage regulation diaphragm dilatancy to follow the string and can't continue and use, so the working life of ordinary rubber voltage regulation diaphragm is lower.
Summary of the invention
In order to overcome the above-mentioned defective that existing rubber voltage regulation diaphragm exists, the utility model provides a kind of pressure regulator valve diaphragm, and it can improve the compressive strength and the anti-dissolubility of pressure regulator valve diaphragm, thereby prolongs its working life.
The technical solution adopted in the utility model be on the rubber substrate compound one deck by resistance to deformation, withstand voltage, corrosion resistant composite membrane.This rubber combined diaphragm had both had the corrosion-resistant and whippy characteristics of elastomer diaphragm, had improved the resistance to deformation of diaphragm, withstand voltage performance again.Its bearing strength and anti-swelling, decay resistance are better than the voltage regulation diaphragm of the individual layer rubber of use at present greatly.
Be described further below in conjunction with the technology contents of drawings and Examples model utility.
Description of drawings
Accompanying drawing is a kind of embodiment's of the utility model pressure regulator valve diaphragm a structural representation.
Among the figure, 1, pallet, 2, the rubber substrate, 3, sealing gasket, 4, the diaphragm link, 5, composite membrane.
Embodiment
Shown in accompanying drawing, present embodiment pressure regulator valve diaphragm comprises pallet 1, rubber substrate 2, sealing gasket 3, rubber substrate 2 following compound one deck resistance to deformations, withstand voltage, corrosion resistant composite membrane 5.Above-mentioned part is combined into an integral body with connection piece 4.Composite membrane 5 can adopt aluminium foil, wash material such as human relations, and present embodiment adopts to be washed the human relations film and be compounded on the rubber substrate.
Claims (1)
- A kind of pressure regulator valve diaphragm comprises rubber substrate (2), it is characterized in that rubber substrate (2) upward compound one deck resistance to deformation, withstand voltage, corrosion resistant composite membrane (5).
