Abstract
The utility model belongs to the design of formula gas sensor is inhaled by force to electrochemistry. The utility model relates to a have big electrolyte apotheca and adopt bonding cooperation sealing washer to make it reach sealed effect, the air chamber adopts polytetrafluoroethylene to make the lining, prevents that the easy absorption of adsorbed gas to the measurement accuracy of sensor has been improved. The large electrolyte storage chamber prolongs the service life of the sensor, and the sensor has reasonable design and simple structure.
Description
The utility model belongs to the design that galvanochemistry is inhaled the formula gas sensor by force.
The strong suction formula gas sensor that U.S. Hua Cheng company produces wherein three electrodes all is arranged on a side, and sealing effectiveness is relatively poor, easy-to-leak liquid, and accumulate to separate liquid measure few, make its serviceable life short.
The purpose of this utility model is that a kind of galvanochemistry of design is inhaled the formula gas sensor by force, this sensor has big electrolytic solution apotheca and adopts bonding fitted seal circle to make it reach sealing effectiveness, air chamber adopts teflon to make lining, prevent easily by the absorption of absorption gas, thereby improved the measuring accuracy of sensor.
Embodiment accompanying drawings of the present utility model is as follows:
Accompanying drawing 1 is the synoptic diagram that galvanochemistry is inhaled the formula gas sensor by force, connect five lines above the socket among the figure (1) and be respectively the work utmost point, to the utmost point, with reference to the utmost point and two thermistors, socket (1) is installed in loam cake (2) centre, there are two bleeder vents the socket both sides, loam cake (2) matches with shell body (13), shell body (13) is a metal buckets, upper press cover (3) has a bleeder vent in the center of circle, below upper press cover (3), there is the shelves ring of a projection to be used for fixing O type circle (4), form a cavity in the shelves ring, O type circle (4) is pressed on the electrode (5), cooperate upper press cover (3) to install, make and form an air storage chamber (21) between upper press cover and the electrode (5), play sealing function, on the bucket wall of drum type upper shell (6), form re-entrant cavity, in the bottom of drum inwall one step is arranged, drum shape lower house (11) is bonding with upper shell (6), on the bucket wall of drum shape, an air admission hole and a venthole are arranged, in inboard, drum shape bucket wall end one step is arranged, one grade of ring is arranged at the step top, on the bucket wall inlet opening (7) is arranged, imbibition material (8) is contained between electrode (5) and the electrode (9), working electrode (9) is connected on the top of lower house (11), O type circle (10) matches with lower cover (16) to seal and pushes down electrode (9), lower cover (16) is a concave body, an air admission hole and a venthole that the bucket wall of corresponding lower house (11) is arranged on the concave wall of lower cover, the draft tube that PTFE makes (12) is passed the air admission hole that lower house (11) connects tetrafluoro inner chamber (14) at the center of lower cover (16) by shell body (13), tetrafluoro inner chamber (14) is installed in the lower cover inwall, its top is pressed in working electrode (9) and goes up a formation air chamber (21), tetrafluoro inner chamber (14) is a concave body, having two holes to divide other at the recess of concave body is air admission hole and venthole, concave body is set in the lower cover (16), the projection of concave body forms one grade of ring, escape pipe (15), pass venthole and lower cover (16) and tetrafluoro inner chamber (14) coupling that shell body (13) enters tetrafluoro inner chamber (14), adding behind the O type circle coincide with lower house is used for fixing electrode (9), lower cover (17) and shell body (13) coupling, the liquid injection hole (18) of electrolytic solution apotheca (19) lower end seals with sealing-plug (20).
The utility model has designed big electrolytic solution apotheca, and its life-span is prolonged, and air chamber adopts teflon to prevent that effectively the absorption of easy adsorbate from improve the sensor measurement precision.
