Quick Details

Product Details

Fiber-rubber diaphragm

Rubber diaphragm with pressure control/diaphragm/seal function is our main product.  

The product combines the unique sealing property of rubber with the strength of the base cloth, which can accurately control the pressure and the movement stroke of parts, and is used by many users.  

The company specializes in producing laminated rubber diaphragm, from the processing of all kinds of flat diaphragm, is now widely used as automobile parts diaphragm, is evaluated as the leading domestic diaphragm production enterprises.  

Rubber diaphragm is divided into

1. Isolation film  

Diaphragm, for short, only isolates the flow, with no pressure difference between the two isolated parts.  

2. Permeable film  

The use of rubber film on gas or liquid has a certain permeability and selectivity of this feature, the role of some fluids.  The membrane itself moves very little or no.  

3.  Sports film  

These films act as seals between stationary and moving parts.  At the same time are generally transmitted power!  

This type of film is most widely used.  

Rubber laminated diaphragm

It is mainly used in valves, control valves, automatic mechanical follow-up devices, switches and counters of flow, pressure, differential, liquid level, constant temperature volume thermal compensation, etc.  Its advantages lie in high reliability, good complexity, long working life and low cost.  

The rubber diaphragm produced by the company is more than 2 million times of bending, thickness in 0.5-5 mm, and can be processed according to the special requirements of customers, meet the temperature of -40℃–300℃, special media, pressure, non-toxic and other requirements.  

1. Develop all kinds of large, small, thick, thin clip cloth diaphragm.  

2. Clamping cloth compressive intensity, according to customer demand, the use of suitable glue, cloth bonding molding.  

3. Rubber materials include NBR, EPDM, CR, NR, SILICONE, FKM, etc.  

4. Fiber cloth has a variety of warp and weft yarn of nylon, dacron, cotton canvas, telescopic cloth, long service life, can accurately and other control components synchronous operation, to ensure the pulse compressed air blowing.
