The utility model has the advantages of simple structure, and high reliability. The utility model can be used for the automatic detection and the control of industries, such as chemical industry, pharmacy, food, biochemistry, etc.
Description
The present utility model is the contrast electrode device that the automatic detecting sensor of a kind of pH value is used.
Conventional forms pH value detecting sensor contrast electrode with glass electrode, the domestic normal pressure sampling and testing that only is used at present, and abroad in detecting pressure-vessel during the pH value of material, the counter-infiltration measure of contrast electrode is to adopt the way of sealing/pump-up to realize.
The purpose of this utility model be to provide a kind of simple in structure, can follow the tracks of in the tested pressure-vessel material pressure and prevent that effectively the automatic pressure of micropore ceramics counter osmosis from following the tracks of the contrast electrode device.
Above-mentioned purpose realizes by following approach.
Automatic pressure of the present utility model is followed the tracks of the contrast electrode device and is made up of pressure chamber (20), outer cover (1), sealing supporting base (2), self-constriction storage capsule (3), support (4), spring (5), retaining head (6), pressure measuring valve (8), blowdown valve (9), woven hose (10), contrast electrode (14), flexible pipe (15), contrast electrode head (16) etc.Its main feature is by a self-constriction storage capsule (3) that fills with saturated KCL solution (21) being housed and by the automatic extension mechanism of the support (4) that is contained in sealing supporting base (2), spring (5), retaining head (6) formation in outer cover (1) and the pressure chamber (20) formed of sealing supporting base (2); Saturated KCL solution (21) in the self-constriction storage capsule (3) links to each other with contrast electrode (14) by woven hose (10).Make the saturated KCL solution in the self-constriction storage capsule (3) under the automatic pressure tracer action, pass through woven hose (10) and flexible pipe (15).
Another feature of this device is on the outer cover (1) of forming pressure chamber (20) and sealing supporting base (2) pressure measuring valve (8) and blowdown valve (9) to be housed respectively, by pressure measuring valve (8) pressure chamber (20) is linked to each other with the tested container air intake opening; (also can directly this device be installed on the tested container, make it directly to contact with measured matter) make the indoor pressure of pressure all the time with tested container in pressure identical, simultaneously under self-constriction storage capsule and automatic extension mechanism effect, automatically realize the supply of contrast electrode pressure tracking and saturated KCL solution, thereby reached the effect that the pressure that can follow the tracks of in the tested pressure-vessel can prevent the micropore ceramics counter osmosis again effectively, realized purpose of the present invention.
Automatic pressure of the present invention is followed the tracks of the contrast electrode device, has reliable operation, simple in structure, pressure from motion tracking; The self-constriction counter-infiltration advantage that has progradation simultaneously.The pH value detecting sensor that itself and glass electrode are formed, the robotization that can be widely used in industries such as chemical industry, pharmacy, food, biochemistry detects and control.
Below in conjunction with accompanying drawing the utility model is elaborated:
Accompanying drawing is the structural representation that automatic pressure is followed the tracks of the contrast electrode device.
Automatic pressure is as shown in the figure followed the tracks of the contrast electrode device and mainly is made up of pressure chamber (20), outer cover (1), sealing supporting base (2), self-constriction storage capsule (3), support (4), spring (5), retaining head (6), pressure measuring valve (8), blowdown valve (9), woven hose (10), contrast electrode (14), flexible pipe (15), contrast electrode head (16), hole pottery (18) etc.Be characterized in by outer cover (1) and have being equipped with one in the pressure chamber (20) that the sealing supporting base (2) of O-ring seal (19) forms and filling with the self-constriction storage capsule (3) of saturated KCL solution (21) and the automatic extension mechanism of being made up of the support (4), spring (5), the retaining head (6) that are contained on the sealing supporting base (2), the interior saturated KCL solution of self-constriction storage capsule communicates with contrast electrode (14) by woven hose (10).
Another characteristics of this device are on outer cover (1) that constitutes pressure chamber (20) and sealing supporting base (2) pressure measuring valve (8) and blowdown valve (9) to be installed respectively; This device is connected with tested container by pressure measuring valve (8), directly contact with measured matter, make the pressure in the pressure chamber (20) identical with pressure in the tested container all the time, (this device can remove outer cover (1), will install directly to be fixed on the pressure vessel) under certain condition.Under self-constriction storage capsule (3) and automatic extension mechanism acting in conjunction, automatically realize the supply of contrast electrode head (16) pressure tracking and saturated KCL solution simultaneously.
In order to realize this purpose preferably, the automatic extension mechanism of this device is to constitute like this:
Self-constriction storage capsule (3) one ends are sleeved in the circular ring plate on support (4) top, between circular ring plate and retaining head (6), spring (5) is housed, this end of self-constriction storage capsule then is sleeved on the retaining head of being made by teflon (6), and both are tightened together by becket (7); The other end of self-constriction storage capsule (3) then penetrates in the center pit of sealing supporting base (2), be packed on the cross web member (13) that has string heart hole by T type sealing pressure head (11) and U type seal pressure cap (12), the woven hose (10) that inserts in its string heart hole can make contrast electrode (14) communicate with self-constriction storage capsule.Make automatic extension mechanism and sealing supporting base (2) keep self-constriction storage capsule to be in normal operating conditions together on the one hand just because of this structure; On the other hand in case when the saturated KCL solution in the self-constriction storage capsule reduces by micropore ceramics (18) infiltration, the tension force of spring (5) can promote the automatic storage capsule (3) that shrinks of retaining head (6) extension makes it return to the optimal retraction state, thereby can prevent the counter-infiltration phenomenon of micropore ceramics all the time effectively, guarantee the operate as normal of contrast electrode.
For guaranteeing that contrast electrode can adapt to the working environment of higher temperature, the present invention makes the contrast electrode head (16) that micropore ceramics (18) is housed separate with contrast electrode (14), is communicated with flexible pipe (15) in addition.
Blowdown valve (9) generally is in closed condition (can open during the gas pressure) when this device duty, only carry out the pressure release can when needs replenish saturated KCL solution.
