Abstract
The utility model discloses a membrane for a flow control valve, wherein, a body is made of asbestos fiber cloth dipped fluorine glue solution, and a composite laminated structure made by polytetrafluoroethylene (PTFE) flake is adhered on the membrane body. With the composite laminated structure, the shearing resistance of the membrane is greatly improved, the mechanical performance of the membrane is good, the matched intensity is between 10 to 20MPa, the elongation at break is between 150 to 350%, and the tear resistance intensity is between 3 to 4KN/m. The utility model has the advantages of overcoming the shortcoming of weak shearing resistance and short service life in the prior art.
Description
Technical field
The utility model discloses a kind of flow control valve diaphragm, belongs to fluid flow control component of machine technical field.
Background technique
The flow control valve diaphragm is a kind of component of Flow valve special use, belongs to easily damaged parts, existing barrier film generally select for use elasticity preferably rubber make, adopt single layer structure, its anti-shearing force is relatively poor, damages easily, working life is very short, needs often to change.
Summary of the invention
The utility model discloses a kind of flow control valve diaphragm, has overcome the shortcoming of existing barrier film anti-shearing force difference.
Technical solution of the present utility model is as follows:
Adopting the asbestos fiber cloth of dipping fluorine glue is the body of barrier film, is attached with ptfe sheet and constitutes straticulate structure on the body of barrier film.
The asbestos fiber cloth of described dipping fluorine glue has the chemical stability of height, anti-petroleum base oils, di esters oil, silicon ethers oil, silicic acid class oil, inorganic acid resistance, the organic and inorganic solvent of anti-majority, medicine etc.At room temperature dipping its volumetric expansion in 27 days only is 13%～15% among 98% the HNO3.
Effect of the present utility model is: adopt asbestos fiber cloth and the compound stratiform structure of ptfe sheet, improved the anti-shearing force of barrier film greatly, mechanical property is good, the intensity that cooperates is between 10～20MPa, elongation at break is between 150～350%, and tearing toughness is between 3～4KN/m.It is poor to have solved existing flow control valve diaphragm anti-shearing force, the shortcoming that working life is short.
Description of drawings
Fig. 1 is the utility model structure principle chart.
Embodiment
According to shown in Figure 1, septum body 1 is by the fabric circular pad of asbestos fiber of dipping fluorine glue, and ptfe sheet 2 is adhesive on the septum body 1 by fluorine and makes straticulate structure.
Claims (1)
1. flow control valve diaphragm is characterized in that: adopting the asbestos fiber cloth of dipping fluorine glue is the body of barrier film, is attached with ptfe sheet and constitutes straticulate structure on the body of barrier film.
