Abstract
A composite pressure sensing anti-corrosion diaphragm box comprises a diaphragm seat (1), a metal diaphragm (2) and a connector (5), and is characterized in that an isolation diaphragm (3) is additionally arranged on the contact surface of the metal diaphragm (2) and a medium, a lining (4) is additionally arranged on the contact part of the connector (5) and the medium, and the isolation diaphragm (3) and the lining (4) are made of polytetrafluoroethylene materials, so that the defect that the metal diaphragm is extremely thin and is extremely easy to corrode by the medium is overcome, and the service life of a product is greatly prolonged.
Description
The utility model relates to the barrier film pressure transmission device of a kind of tensimeter and pressure unit.
Before the utility model, the prior art pressure tester has multiple: directly by pressure medium driving spring tubular type tensimeter, make the bourdon tube distortion, by physical construction and movement, pointer rotates and shows force value; The direct contact pressure pressure-sensitive diaphragm of pressure medium is also arranged, produce pressure drag and capacitance variations, measure the pressure medium value through metering circuit.
The tensimeter that state inner sensor factory produces and the bellows of transmitter, it comprises film seat, diaphragm and connector, and diaphragm is positioned between film seat and the connector, and diaphragm relies on being threaded between film seat and connector to compress.Be actually used in industrial occasions, because of medium is varied, factory often designs the diaphragm and the connector of various material, and wherein diaphragm has: 1Cr18Ni9Ti, OCr19Ni10, OCr19Ni10Mo2Ti, Hastelloy, Monel, tantalum etc.; Connector is commonly used to be had: 1Cr18Ni9Ti, OCr19Ni10, OCr19Ni10Mo2Ti etc.Because diaphragm plays conducting pressure, its manufactured size is all very thin, and only 0.05-0.2mm only in this way could guarantee that measured pressure has certain degree of accuracy.Because of diaphragm is very thin, in corrosive medium, very easily produce spot corrosion just, and diaphragm was lost efficacy.In some corrosive medium, the diaphragm of Ha Shi B, Ha Shi C alloy is also very short serviceable life even.
Connector is when selection in addition, and also difficulty satisfies the needs of various corrosive mediums, and in some medium, its corrosion speed is also very fast.
The purpose of this utility model provides the anticorrosion barrier film box of a kind of combined pressure sensing, prevents the corrosion of medium to diaphragm and connector.
The purpose of this utility model is achieved in that
By comprising in the bellows that film seat, metallic membrane and connector form, metallic membrane contacts on this side with medium, increases by an isolation diaphragm, and this isolation diaphragm and metallic membrane are fitted fully, and are full of oil between isolation diaphragm and metallic membrane; Connector and medium contact portion increase lining, and lining and isolation diaphragm are selected the teflon material for use.
The utility model reaches the part at the connector contact medium owing to increased isolation diaphragm, has increased lining, and medium is not directly contacted with connector with metallic membrane, has avoided the corrosion of medium to metallic membrane and connector.And, guaranteed the transmission of pressure, thereby guaranteed tonometric degree of accuracy owing between isolation diaphragm and metallic membrane, be full of oil.Because isolation diaphragm and lining are selected teflon for use, are applicable to most media in the industry.Material to metallic membrane and connector does not have specific (special) requirements, thereby reduces spare part quantity and cost greatly, and the anticorrosion instrument life-saving 3-5 that makes than metal material doubly has the unrivaled ratio of performance to price.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Accompanying drawing is the sectional view according to the anticorrosion barrier film box of combined pressure sensing that the utility model proposes.
Below in conjunction with accompanying drawing, describe in detail according to the concrete device that the utility model proposes.
This device comprises film seat (1), metallic membrane (2), connector (5), the direction of arrow is medium among the figure, on metallic membrane (2) and the medium surface of contact, increase an isolation diaphragm (3), this isolation diaphragm (3) is fitted fully with metallic membrane (2), and is full of oil between metallic membrane (2) and isolation diaphragm (3); Connector (5) contact medium part increases lining (4); Lining (4) is selected the teflon material for use with isolation diaphragm (3).
Claims (2)
1. the anticorrosion barrier film box of combined pressure sensing comprises film seat (1), metallic membrane (2), connector (5), it is characterized in that on metallic membrane (2) and medium surface of contact, increase an isolation diaphragm (3), be full of oil between metallic membrane (2) and isolation diaphragm (3); The part of connector (5) contact medium increases lining (4).
2,, it is characterized in that isolation diaphragm (3), lining (4) select the teflon material for use according to claims 1 described barrier film box.
