Abstract
The utility model discloses a novel fuel oil liquid level pressure sensor. The novel fuel oil liquid level pressure sensor comprises a disc-shaped machine body, wherein the middle portion of the right end of the disc-shaped machine body is concaved leftwards to form a round hole cavity, the right end of the disc-shaped machine body is connected with an annular flange cover in a screwing mode through bolts, a nanometer material compound elastic membrane is clamped between the annular flange cover and the disc-shaped machine body, the nanometer material compound elastic membrane is located in the middle of the geometric dimension of the novel fuel oil liquid level pressure sensor, the nanometer material compound elastic membrane and the round hole cavity form a sealed cavity, a wire hole is formed in the lateral wall of the sealed cavity, and a signal wire penetrates through the wire hole in a sealed mode and is in electric connection with the nanometer material compound elastic membrane. The novel fuel oil liquid level pressure sensor is small in size, stable in performance, high in reliability, easy to install, low in manufacturing cost, and long in service life.
Description
Technical field
The utility model relates to pressure transducer, especially a kind of pressure transducer of fuel level.
Background technology
Existing oil gauge existing problems are a lot, and for example the useful life of resistance-type is very short, and what have only can use 3 months.Capacitive performance is subjected to oil product and environmental impact larger, have measuring error, and cost is higher.And no matter be the ultrasonic type that resistance-type, condenser type or just begun tested, to install complicatedly, quantities is large.For example to bore larger hole at fuel tank, also want a plurality of screws to install.Ultrasonic type then must carry out high-precision grinding and buffing to tank surface, and not only workload is large, and cost is high, and is not durable very much, and performance reduces rapidly after a period of time.
The utility model content
The purpose of this utility model is: a kind of novel fuel liquid level pressure transducer is provided, and volume is little, stable performance, and reliability is high, and low cost of manufacture, long service life easily are installed.
For achieving the above object, the utility model can be taked following technical proposals:
A kind of novel fuel liquid level of the utility model pressure transducer, comprise: the disc body, the right-hand member middle part of described disc body is recessed to form the circular hole chamber left, disc body right-hand member is bolted with the annular flange lid by bolt, between described annular flange lid and disc body body, be folded with nano material composite elastic film, this nano material composite elastic film is positioned at the centre of the physical dimension of this novel fuel liquid level pressure transducer, the sealed chamber that nano material composite elastic film and circular hole chamber consist of, the sidewall of sealing chamber is provided with wire guide, and signal wire penetrates and is electrically connected with described nano material composite elastic film by this wire guide sealing.
The left end that the right-hand member of described disc body is provided with inner seal ring, annular flange lid is provided with exterior seal ring.
The right-hand member of described disc body is evenly equipped with 3 pads.
Described wire guide is arranged on the screw, and this screw runs through the sidewall of disc body.
The lateral wall of described disc body is provided with and picks and places the rope screw.
Compared with prior art the beneficial effects of the utility model are: owing to adopting technique scheme, between described annular flange lid and disc body body, be folded with nano material composite elastic film, this nano material composite elastic film is positioned at the centre of the physical dimension of this novel fuel liquid level pressure transducer, the sealed chamber that nano material composite elastic film and circular hole chamber consist of, the sidewall of sealing chamber is provided with wire guide, signal wire penetrates and is electrically connected with described nano material composite elastic film by this wire guide sealing, this structure, what adopt is that (this technology has been applied for US Patent No. 8393229 to nano material composite elastic film, and produced by Hong Kong An Ruipu company), volume is little, reliability is high, easily install, low cost of manufacture (be approximately existing product half), stable performance, and can use for a long time by changing core part.Nano material composite elastic film is in the centre of physical dimension at centerline direction, such structure, no matter which face of the utility model novel fuel liquid level pressure transducer below, nano material composite elastic film all is in the same level position.
Further beneficial effect is: signal wire links to each other with the outside by the wire guide that is arranged on the screw, can guarantee the reliability of sealing and signal wire.The lateral wall of disc body is provided with and picks and places the rope screw, and the annular distance that picks and places the rope screw is worn thin tightwire or gimmal, in order to pick and place oil gauge.Pad is used for realizing 3 contacts.
