Abstract
A piston type differential pressure gauge, is provided with pointers and a meter dial at the outer surface of the gauge body, a pipeline is arranged in the gauge body, one end of the pipeline is provided with a modulus linear elastic device, one end of which is connected with one end of a piston sensor, the other end of the piston sensor is connected with one surface of an unidirectional seal diaphragm, the other surface of the unidirectional seal diaphragm is connected with a magnet which is linkaged with pointers. Pipe joints are arranged at both end ports of the pipeline. The utility model has the advantages that the indication range is greatly improved because of unidirectional seal diaphragm and the modulus linear elastic device and is between 0 and 35 kPa or between 0 and 1000kPa according to the user requirement. The differential pressure gauge is in particular used in the environment of high differential pressure value and low-rise indication precision.
Description
Technical field
The utility model belongs to the optical, mechanical and electronic integration instrument and meter, particularly a kind of piston type differential pressure gauge.
Background technology
Existing machinery formula differential pressure gauge adopts dish-type spring wire structure mostly, can only indicate minute-pressure poor.The differential pressure gauge that can indicate High Pressure Difference is adopts pressure sensor formula structure all, must need power supply to work.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of piston type differential pressure gauge is provided.
The technical solution of the utility model is:
A kind of piston type differential pressure gauge, it is characterized in that: pointer and index dial are arranged at the table external surface, in the table body, a pipeline is arranged, one pipeline, one end is provided with the linear Billiard apparatus of permanent modulus, linear Billiard apparatus one end of permanent modulus connects piston sensor one end, the piston sensor other end connects one-way sealing diaphragm one side, and one-way sealing diaphragm another side connects magnet, magnet interlock pointer.
The two-port of pipeline has pipe connecting piece.
The utility model characteristics are:
The linear Billiard apparatus of novel uniaxial pressure diaphragm and permanent modulus makes indicating range increase greatly, and actual indicating range can be according to customer requirements at range: optional between 0～35kPa to 0～1000kPa.
This product is specially adapted to differential pressure numerical value height, and the less demanding environment of pointing accuracy uses.
Shape: physical dimension: 92 (wide) * 96 (height) * 56 (deeply); Mounting hole: 2-φ 5, pitch-row 83mm; Dial plate diameter: 2.5 inches.

Fig. 2 is the inner structure synoptic diagram of piston type differential pressure gauge
Among the figure: 1, table body, 2, pointer, 3, index dial, 4, the linear Billiard apparatus of permanent modulus, 5, piston sensor, 6, magnet, 7, the one-way sealing diaphragm, 8, pipeline, 9, pipe connecting piece
Embodiment
Piston type differential pressure gauge as shown in Figure 1, 2, its structure: adopt hydraulic jack, piston structure sensed pressure poor, drive needle deflection by magnetic coupling mechanism, indication pressure reduction.
Its annexation:
The back connects, and the standard interface size is 1/4 " taper-thread, also can be according to the customer requirements specific customization.
When being installed, differential pressure indicator to distinguish the mark of HI (high pressure) and LO (low pressure).The high pressure port that HI represents, what LO represented is low pressure end.If equipment has been installed reverse and will do not worked.
Because magnet movement, instrument necessarily can not be directly installed on the steel body surface, otherwise deviation of reading will occur.To lay this instrument with the pad or the aluminum fixed support of no magnetic away from magnetic conductive metal face 30mm at least.
Instrument should be installed on the horizontal level, with the site error of avoiding producing because of gravity.
Operating principle:
Pressure on monitored intrasystem two differences acts on the relative both sides of a piston sensor of 5. 7. being made up of jointly with the one-way sealing diaphragm piston.The variation of pressure reduction will cause piston sensor and the 6. proportional motion change of attached magnet.
Linear displacement takes place in piston sensor under the acting in conjunction 4. of the linear Billiard apparatus of two ends differential pressure and permanent modulus, it on attached magnet 6. be embedded in independent endoceliac armature and produce magnetic coupling and drive armature and rotate.2. pointer on the armature demonstrates pressure difference at index dial on 3..
