Abstract
The utility model discloses a device for measuring solution PH value, which mainly comprises a fixed seat, a press plate, a cover plate, joints and a PH probe sensor. A through hole is axially arranged in the fixed seat. The two ends of the through hole are respectively connected with two joints which are respectively connected with a solution inlet pipe and a solution outlet pipe. The press plate is fixed on the fixed seat through a bolt. A corresponding locking hole is arranged on the press plate and the cover plate. The bolt penetrates through the locking hole and fixes the cover plate on one side of the press plate. A wiring trough is arranged on the side of the press plate in contact with the cover plate. A contact is arranged at one end of the PH probe sensor and the other end of the PH probe sensor extends into the through hole of the fixed seat. Conducting wires are welded on the contact. The conducting wires are led out through the wiring trough. The utility model has the advantages that the structure is simple, the installation and the maintenance are convenient, the cost is low, the performance is stable, and the PH value of the solution used in the hemodialysis machine and the dialyzer reuse device can be accurately measured.
Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly a kind of device of measuring the solution pH value.
Background technology
Numerous industries all can be to the measuring of solution or liquid pH value, and is very extensively and significant.Especially the haemodialysis control unit in the medical industry, dialyser multiplexing machine, this kind equipment is measured even more important to used solution pH value, because whether these solution pH values meet the requirements directly influence is absolutely necessary so the pH value that uses solution in this quasi-instrument is measured monitoring to patient's curative effect and safety.Present measurement mechanism structure is comparatively complicated, and the making maintenance difficulty is big, and the cost height is so need to improve.
The utility model content
The purpose of this utility model is to disclose a kind of simple in structure, is applicable to measure haemodialysis control unit, dialyser multiplexing machine, the device of measurement solution pH value convenient for installation and maintenance.
For reaching the foregoing invention purpose, the technical scheme that is adopted is: a kind of device of measuring the solution pH value, mainly comprise holder, pressing plate, cover plate, joint and PH probe inductor, have a through hole in the holder vertically, the through hole two ends are connected with and advance/joint that drain pipe is connected, pressing plate by bolt on holder, PH probe inductor is arranged in the holder, pressing plate and cover plate are provided with corresponding locking hole, bolt penetrates on this locking hole and cover plate is fixed in a side of pressing plate, and a side that contacts with cover plate on the pressing plate also has metallic channel; One end of each PH probe inductor is provided with contact, and the other end extend in the through hole of holder, is welded with lead on the contact, and lead is drawn by metallic channel jointly.
Holder one side has the threaded hole of several through holes and fixation clip, is equally spaced at interval between through hole and the threaded hole; Have contact fixed orifice corresponding and the through hole corresponding on the pressing plate with threaded hole with the holder through hole.
Through hole on the described holder, wherein at least one through hole is embedded is connected to a cup cover, has been respectively charged into PH probe inductor in all the other through holes, and PH probe inductor inserts in the contact fixed orifice.Be incorporated with temperature sensor in the cup cover.The position that the cup cover outside contacts with holder is socketed with O-ring seal.
Of the present utility model simple in structure, convenient for installation and maintenance, with low cost, stable performance can be measured the pH value that uses solution in the haemodialyser multiplexing machine exactly.
