Abstract
The utility model relates to a slide block type differential pressure gauge. An outer surface of a gauge body is composed of a slide block with a pointer and a scale plate. The inside of the gauge body is provided with a pipeline. One end of the pipeline is provided with a constant modulus linear elastic device. One end of the constant modulus linear elastic device is connected with one end of a piston sensor. The other end of the piston sensor is connected with one side of a unidirectional seal membrane. The other side of the unidirectional seal membrane is connected with a magnet. The magnet is connected with a magnet slide block. The slide block type differential pressure gauge is characterized in that a unidirectional pressure membrane and the constant modulus linear elastic device greatly increase the indicating scope, and the actual indicating scope can be chosen at will in a measuring range from 0-300kPa to 0-1000kPa based on the requirement of a user. The slide block type differential pressure gauge is especially suitable for the environment which has a high differential pressure value and does not have the requirement of high indication precision.
Description
Technical field
The utility model belongs to the optical, mechanical and electronic integration instrument and meter, particularly a kind of slide block 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
The utility model technical matters to be solved is: a kind of slide block type differential pressure gauge is provided.Do not use power supply.
The technical scheme of the utility model is:
A kind of slide block type differential pressure gauge; It is characterized in that: in the table body pipeline is arranged; End cap is equipped with at the two ends of pipeline, and the end with the linear Billiard apparatus of permanent modulus in the end cap of one of which end is connected, and the linear Billiard apparatus other end of permanent modulus connects piston; Piston is equipped with the one-way sealing diaphragm on the outer border, and the piston outer end connects magnet; In the pipeline outside one axial groove is arranged, the magnet slide block is housed in the axial groove, this magnet slide block matches with the magnet of piston outer end, and the outer table surface of axial groove is the scale dial plate, and the scale dial plate has glass outward.
On the pipe ends end cap through hole is arranged, through hole connecting pipe fitting.
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 0～300kPa to 0～1000kPa.
It is higher that this product is specially adapted to differential pressure numerical value, and the less demanding environment of pointing accuracy uses.
Shape: physical dimension: 45 (wide) * 34 (height) * 113 (deeply); Mounting hole: 2-φ 5, pitch-row 80mm.
Do not use power supply.Energy savings.

Embodiment
As Fig. 1,2, shown in a kind of slide block type differential pressure gauge; In the table body pipeline is arranged; End cap is equipped with at the two ends of pipeline, and the end with the linear Billiard apparatus of permanent modulus in the end cap of one of which end is connected, and the linear Billiard apparatus other end of permanent modulus connects piston; Piston is equipped with the one-way sealing diaphragm on the outer border, and the piston outer end connects magnet; In the pipeline outside one axial groove is arranged, the magnet slide block is housed in the axial groove, this magnet slide block matches with the magnet of piston outer end, and the outer table surface of axial groove is the scale dial plate, and the scale dial plate has glass outward.On the pipe ends end cap through hole is arranged, through hole connecting pipe fitting.
The slide block type differential pressure gauge, its structure: adopt linear Billiard apparatus (critical piece is a spring) of permanent modulus and piston structure sensed pressure poor, drive the skew of magnet slide block through the magnetic coupling mechanism, indication pressure reduction.
Its annexation:
Two ends connect, and the standard interface size is 1/4 " pipe thread, also can be according to the customer requirements specific customization.
, differential pressure indicator to distinguish the mark of HI (high pressure) and LO (low pressure) when being installed.The high pressure port that HI representes, 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. 6. being made up of jointly with the one-way sealing diaphragm piston.The variation of pressure reduction will cause piston sensor and the 7. proportional motion change of attached magnet.
Linear displacement takes place down in the acting in conjunction 10. of the linear Billiard apparatus of two ends differential pressure and permanent modulus in piston sensor, it on attached magnet 7. and the magnet slide block of showing in the body mutual attraction is arranged between 8., thereby drive magnet slide block is subjected to displacement.The indicator graduation lines that carries on the magnet demonstrates pressure difference at the scale dial plate on 9..
