Description
Technical field
The present invention relates to a kind of salinometer, relate in particular to a kind of salinometer with asepwirator pump protective device.
Background technology
Salinity is the fundamental of all oceanographic survey projects, and existing SYA2-2 type laboratory salinometer is the instrument that a kind of pin-point accuracy has the measurement seawater sample salinity of intelligent function.This instruments design novelty, accuracy height, simple to operate, intelligent strong, cost an arm and a leg, maintain the leading position at home, its basic mechanical design feature reaches international level with quasi-instrument.The air-breathing sampling system of Cai Yonging has wherein reduced the use amount of standard substance and sample, has reduced the standard substance use cost, has improved work efficiency.But owing to comprise the closure of the air-breathing sampling system of asepwirator pump, in use, its asepwirator pump is taken into account removal waste fluid and is imported the function of liquid, directly link to each other with waste liquid pool,, when the waste liquid liquid level reach a certain height, need the artificial waste liquid of discharging in time if liquid level is too high in the waste liquid pool, if the big or misoperation of fluctuating range about the liquid level in the waste liquid pool, liquid very easily enters in the asepwirator pump, makes asepwirator pump corrosion even burns, and causes this instrument cisco unity malfunction and damages.Especially this instrument in marine on-the-spot the use, in case damage, has not only lost expensive instrument, and certainly will influence the carrying out that overall work is measured in oceanographic survey for a long time.
Summary of the invention
The object of the invention provides a kind of salinometer with asepwirator pump protective device, to overcome the deficiencies in the prior art.
The present invention is on the basis of existing laboratory salinometer, and consider to guarantee the normal operation of salinometer, between the entrance point of salinometer asepwirator pump and waste liquid pool specialized designs an asepwirator pump protective device.
Technical scheme of the present invention comprises the salinometer main body that has asepwirator pump and waste liquid pool, it is characterized in that also comprising that the upper end connects the asepwirator pump protective device of the entrance point of asepwirator pump, lower end insertion waste liquid pool, is divided into three chambeies from top to bottom by valve seat and guide way in the tubular body of this asepwirator pump protective device: the above cavity wall side of valve seat is provided with a safety valve that relies on air intake opening to communicate with ambient atmosphere; Cavity wall side between valve seat and the guide way is provided with an air admission hole; Be provided with a float in the cavity below the guide way, this float fulcrum pin is upwards fixed a valve rod that passes guide way, and the valve rod top is provided with a valve head.This buoys float arrives at valve head in waste liquid and along with liquid surface lifting in the waste liquid pool or lifts off a seat, and reaches to prevent that waste liquid from entering the purpose in the asepwirator pump.
Above-mentioned safety valve can be arranged on outside the waste liquid pool.
Technology of the present invention is simple and direct, can control the duty of asepwirator pump automatically, got rid of since jolt wait arround environment and the improper asepwirator pump that causes of manual operation corrode even burn, thereby guaranteed the continuity and the stability of on-the-spot salimity measurement, greatly prolonged the serviceable life of salinometer and reduced maintenance cost.

Embodiment
As shown in drawings, a kind of salinometer with asepwirator pump protective device, comprise the salinometer main body 14 that has asepwirator pump 1 and waste liquid pool 8, it is characterized in that also comprising that the upper end connects the asepwirator pump protective device of the entrance point of asepwirator pump 1, lower end insertion waste liquid pool 8, be divided into A, B, three chambeies of C from top to bottom by valve seat 3 and guide way 5 in the tubular body 2 of this asepwirator pump protective device: the wall side in valve seat 3 above A chambeies is provided with a safety valve 9 that relies on air intake opening 10 to communicate with ambient atmosphere; B chamber wall side between valve seat 3 and the guide way 5 is provided with an air admission hole 11; Guide way is provided with a float 7 in the C chamber below 5, and this float 7 is fixed a valve rod 6 that passes guide way 5 on axially, and valve rod 6 tops are provided with a valve head 4.This float 7 floats in the waste liquid and along with liquid surface liftings in the waste liquid pool 8 valve head 4 is arrived at or lift off a seat 3, reaches the waste liquid that prevents waste liquid pool 8 and enters in the asepwirator pump 1.
As shown in drawings, above-mentioned safety valve 9 also can be arranged on outside the waste liquid pool 8, but no matter how safety valve 9 is provided with, and its air admission hole 10 all will be connected with the atmosphere outside the waste liquid pool 8.Above-mentioned safety valve 9 is commercially available copper normally closed one-way relief valves.Sample suction port 13 and removal waste fluid mouth 12 are the existing import and exports up and down of waste liquid pool 8 walls.
As the tubular body 2 of the supporting body of above-mentioned asepwirator pump protective device, its height is 80mm, and diameter is 25mm, and its upper end is fixed on waste liquid pool 8 cover plates and with the entrance point of asepwirator pump 1 and is connected, in the waste liquid of its lower end insertion waste liquid pool 8.In the tubular body 2, be divided into three cavitys by valve seat 3 and guide way 5, the valve head 4 at valve rod 6 tops of float 7 forms a valve in valve seat 3 wherein and the C chamber, realizes the control to the air-breathing sampling system of salinometer.
Since specialized designs of the present invention the asepwirator pump protective device, when asepwirator pump starts the back waste liquid and is entered waste liquid pool 8 and liquid level and reach a certain height by sample suction port 13, float 7 promotes valve head 4 by valve rod 6 and rises to valve seat 3 places, cut off the path of air admission hole 11 and asepwirator pump 1, thereby avoid because the too high waste liquid that causes of waste liquid pool liquid level enters asepwirator pump; Simultaneously safety valve 9 is opened air intake opening 10 automatically because A chamber air pressure is lower than external pressure, and asepwirator pump 1 is communicated with the external world, prevents that excessive causing of asepwirator pump 1 load from burning.At this moment, the salinometer break-off needs by the waste liquid in the removal waste fluid mouth 12 discharging waste liquid pools 8 liquid level to be dropped to below the safety level.Valve head 4 makes air admission hole 11 be communicated with asepwirator pump 1 along with liquid level descends, and safety valve 9 cuts out air intake opening 10 automatically simultaneously, and salinometer works on.
