Description
Technical field
The utility model relates to a kind of isolating valve, especially relates to a kind of telescopic isolating valve that can make the online dismounting of plug-in type pH electrode and installation.
Background technique
At present in a plurality of fields such as petrochemical industry, biofermentation, environmental protection water treatments, because production technology and the needs of controlling automatically, all be extensive use of the plug-in type pH electrode of online detection material pH value, the pH that directly inserts equipment or pipeline by connecting thread or flange detects the position.Because the continuity of these field production technologies, make the pH electrode onlinely overhaul or to change to become basic but also very urgent requirement, if because the pH electrode failure needs maintenance, also remove and change after the discharges material and have no alternative but stop production, will bring tremendous loss for manufacturing enterprise.
Based on this requirement, have dual mode to realize online dismounting and the installation of pH electrode now usually:
First kind is the mode that adopts the bypass water conservancy diversion, mouthful a common root cutting-off valve is installed detecting, and during valve opening feed liquid is guided to flow cell, and the pH electrode is installed on the flow cell to contact with the material of bypass and detects.When the pH electrode need overhaul or change, close the root cut-off valve.The defective of this mode maximum is the accuracy that detects for guaranteeing, continuous the passing through of material discharged behind the flow cell, discharging month after month throughout the year not only causes waste to go back serious environment pollution, and when tested material need adopt extraordinary material to the corrosivity of pipeline or equipment material, the material of flow cell selects difficulty big, the cost height, and maintenance workload and the maintenance cost of numerous flow cell system itself are also very big.
The second way is the valve sets to pH electrode deployment complexity, when the pH electrode needs on-bne repair or changes, and throttle down.The greatest drawback of this mode is that valve and pH electrode are two parts of split, there is feed liquid accumulation dead band, may cause the induction position of electrode tip can not in time touch the freshest feed liquid, especially at some pH regulons, variation according to material pH value, when in time feeding back testing signal and control automatically by the pH electrode, can cause pH electrode value to lag behind, can not realize the accurately technology purpose of control.
The model utility content
The purpose of this utility model is exactly the telescopic isolating valve that can make the online dismounting of plug-in type pH electrode and installation that a kind of simple in structure, cheap, good seal performance is provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of telescopic isolating valve that can make the online dismounting of plug-in type pH electrode and installation, this isolating valve comprises valve seat and valve head, wherein,
Described valve seat comprises valve sleeve, valve seat adpting flange and valve base seal, and described valve seat adpting flange is located at the bottom of valve sleeve, and described valve base seal is located at the top of valve sleeve,

The outside of described valve head sleeve openings end is offered and is that outside thread, the inboard of described valve sleeve offer the screw thread for being complementary with outside thread, and described valve head sleeve can precession or back-out in valve sleeve.
When the valve head sleeve in valve sleeve during precession, the gasket seal on the valve head sleeve and be located between the valve base seal on valve sleeve top and seal butt, opening is covered by valve sleeve inside.
The inboard of described valve head sleeve openings end is offered and is internal thread, and the valve head sleeve is connected with pH electrode thread in being located at the valve head sleeve by internal thread.
The opening end of described valve head sleeve is provided with adpting flange, is tightly connected by adpting flange and the pH electrode that is located in the valve head sleeve.
Described opening is provided with 6, evenly is laid in the circumferential of valve head sleeve.
Described valve seat adpting flange is installed in detection mouth place on equipment or the pipeline by bolt.
Be positioned at the end inductive head of pH electrode of valve head sleeve inner near the position of opening.
The pH electrode is installed the back and valve head becomes one, and when unlatching or closing operation isolating valve, rotates simultaneously with valve head, and the pH electrode is relative with valve head static.The position of opening is near the inductive head position, end of pH electrode, and guaranteeing isolating valve under opening state, the material flow of passing through from each opening direction makes inductive head can detect the pH value data information of tested material truly, timely through inductive head.
Valve head and valve seat can adopt composite materials such as metallic material, nonmetallic material or carbon steel lining PO according to the corrosivity requirement of material medium to material.Gasket seal adopts the F4 material.
Telescopic isolating valve of the present utility model, being directly installed on needs to detect on the equipment or piping design position of material pH value, and under the working state, valve head is lifted off a seat, and material enters in the valve head sleeve through opening, contacts with pH electrode inductive head.Flow or turbulent condition as long as the material in equipment or the pipeline is, the material of pH electrode inductive head contact is exactly runner or turbulent condition, this be in time, the key of actual response material pH value.
When the pH electrode needed online dismounting, the precession valve head until the gasket seal on the valve head sleeve and be located between the valve base seal on valve sleeve top and seal butt, illustrated between valve head and the valve seat and closes fully that opening is covered by valve sleeve inside.At this moment the pH electrode can be disassembled and overhaul or change.After reinstalling the pH electrode, valve head is screwed out when being positioned at outside the valve sleeve to opening, valve just has been in the normal working of unlatching again.This operation can be when equipment or pipeline normally move online carrying out, and do not need to stop production, thereby guarantee the continuity of producing.
Compared with prior art, the utlity model has following advantage and beneficial effect:
When (1) guaranteeing that the pH electrode normally moves, do not need discharges material, save production cost, reduce environmental pollution.
(2) detecting the position does not have the feed liquid dead band, makes pH electrode inductive head directly contact tested material in equipment or pipeline, can detect the pH value data of material really, timely.
(3) airtight performance is good: adopt the soft seal pad of F4 material, cooperates with valve base seal, can still guarantee the sealing load of two seal faces, thereby guarantee good sealing effect by rotating under the situation that the threaded adjusting impacting force guarantees to use repeatedly.The sealing thread at this position can adopt metric system, goods NPT made in Great Britain etc. to carry out accessory processing according to the screw type of pH electrode.
(4) simple in structure, cheap: as under the situation that many places pH electrode is installed, to compare with conventional valves prescription formula, can obviously reduce engineering cost.
