Abstract
A PH probe flow-through cell comprises a cell cover, a clamp, an O-shaped sealing ring and a cell body, wherein the outer periphery of the bottom of the cell cover is in a chuck shape, and the inner surface of the cell cover is provided with internal threads for fixing a PH probe with threads; the tank body is provided with three connectors, wherein the outer periphery of the top of the upper connector is in a chuck shape and is detachably connected with the tank cover through a clamping hoop, and the left connector and the right connector are used for being in butt joint with a field pipeline; the O-shaped sealing ring is arranged between the tank cover and the tank body; the clamp equipment is used to pond lid and cell body, only needs open the clamp during calibration probe, takes out PH probe and pond lid from the cell body together again, does not need rotatory PH probe body, and the assembly is simple and convenient, need rotatory PH probe body when having solved current flow-through cell and dismantling, and then causes the cracked problem of probe tail end signal line.
Description
Technical Field
The utility model relates to an environmental protection field especially relates to a circulation pond of PH probe.
Background
Along with the implementation of the new pollution source on-line monitoring standard of the environmental protection department, the requirement on the accuracy of PH monitoring is higher, the frequency of field PH probe calibration and verification is correspondingly increased, the conventional PH probe flow cell generally adopts a common tee joint, the upper port is an internal thread, a screw-in probe is screwed in, and the left port and the right port are connected with a field pipeline. The PH probe has the following defects that the tail end of the PH probe is provided with a signal wire fixed on a display, the front end of the PH probe is screwed in a flow cell, a worker calibrates the probe at each time and needs to rotate the probe out of the flow cell, the signal wire at the tail end can be stressed like a clockwork spring, the disassembly frequency is high, and the wire at the tail end of the probe can be broken. Most of the probes are imported products, the damage and replacement cost is high, the probes need to be rotated for multiple circles during disassembly and installation, the probes need to be rotated, the stress of the signal lines is adjusted, and time and labor are wasted.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned weak point of current flow-through cell, an object of the utility model is to provide a PH probe flow-through cell aims at solving current PH probe flow-through cell and dismantles inconvenient and easily cause the cracked problem of probe tail end signal line when calibration probe.
The utility model provides a technical scheme that its technical problem adopted is:
a PH probe flow-through cell comprises a cell cover, a clamp, an O-shaped sealing ring and a cell body, wherein the outer periphery of the bottom of the cell cover is in a chuck shape, and the inner surface of the cell cover is provided with internal threads for fixing a PH probe with threads; the tank body is provided with three connectors, wherein the outer periphery of the top of the upper connector is in a chuck shape and is detachably connected with the tank cover through a clamping hoop, and the left connector and the right connector are used for being in butt joint with a field pipeline; the O-shaped sealing ring is arranged between the tank cover and the tank body.
Furthermore, the O-shaped sealing ring is made of FKM materials.
Further, the pool body is made of UPVC material, the hoop is made of stainless steel material, and the pool cover is made of UPVC material.
The utility model has the advantages that:
when the PH probe is installed for the first time, the PH probe is screwed on the tank cover, and the tank cover is connected and assembled with the tank body through a clamp. When regularly calibrating the PH probe in later stage work, only need open the clamp, together take up PH probe and pond lid, need not repeated back-out probe and screw in probe again, the effectual cracked problem of probe tail end signal line because repeated rotatory atress that has avoided has also saved the time of whole calibration operation simultaneously.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a schematic perspective view of a PH probe flow cell according to the present invention;
fig. 2 is an exploded view of the PH probe flow cell of the present invention.
In the figure, 1-tank cover, 2-clamp, 3-O-shaped sealing ring and 4-tank body.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, in an embodiment of the present invention, a PH probe flow cell includes a cell cover 1, a clamp 2, an O-ring 3, and a cell body 4, wherein an outer periphery of a bottom of the cell cover 1 is in a chuck shape, and an inner surface of the cell cover is provided with an internal thread for fixing a PH probe with a thread; the tank body 4 is provided with three ports, wherein two ports are arranged on the left and right of the tank body 4 and are a liquid input port and a liquid output port, and the field pipelines are butted in a mode of insertion and viscose sealing; the outer periphery of the top of the upper opening is provided with a chuck shape matched with the tank cover 1 and assembled with the tank cover through a chuck. A circular groove is arranged on the plane of the chuck opening for fixing an O-shaped sealing ring, the inner diameter of the chuck opening is consistent with the inner diameter of the O-shaped sealing ring 3, the outer diameter of the chuck opening is consistent with the outer diameter of the O-shaped sealing ring 3, the O-shaped sealing ring 3 is placed on the plane of the chuck opening at the upper opening of the tank body 4, the bulge of the O-shaped sealing ring corresponds to the groove on the chuck opening at the upper end of the tank body 4,
and then the lower chuck opening of the tank cover 1 is correspondingly placed on the O-shaped sealing ring, the bulge of the O-shaped sealing ring corresponds to the groove on the lower chuck opening of the tank cover 1, and then the tank body 4, the O-shaped sealing ring 3 and the tank cover 1 are clamped and fixed together by the hoop 2.
